If a Skimmer stored most of their weight, then got a running start. Could they run across the surface of water? I'm not a physicist and I can't bothered to try, so I'm asking you guys if this is plausible.

Steelrunners are a bit wonky in how they deal with physics (like F-iron); they are able to resist the force of the Gs put on their body from moving quickly, but aren't able to endure the extra heat caused by friction or air compression. The thing that I'm confused on right now is that F-steel is somewhat temporal in nature (i.e., they can even Allomantically burn their metals faster), which probably means their interaction with physical objects is similar to that of A-Bendalloy. Does this mean that if a Steelrunner punched an enemy while tapping 3x their normal speed that it still wouldn't hit with any more force than if they hadn't tapped speed, similar to how A-Bendalloy siphons off the extra energy of things that enter and exit it? What if they instead picked up a club and swung it at an enemy at 3x speed? It's not technically effected by their Feruchemy (F-steel being completely internal as opposed to A-Bendalloy), so the extra speed shouldn't be siphoned off no matter how Feruchemical speed works. But if this is the case, would the Steelrunner have to put 3x the strength into swinging it, making it much, much harder to actually use their speed? And if part of a Steelrunner's adaptation of their Spritweb to the use of steel Feruchemy is to enhance their strength to deal with this difficulty with interacting with objects at high speed, would this contribute to a Steelrunner's Feruchemical attribute being overall less efficient than other Feruchemical powers, as more Investiture must be siphoned off to deal with the consequences of using that power?

I've introduced myself in other places, but I'm a physics professor who is also a big fan of Sanderson's works. There are a lot of in-depth physics discussions on various topics all over this forum. This isn't that. I wanted to start a thread for those who have simple questions about Cosmere (or other Sanderson works) physics, but without diving off the deep end. So, if you have a question but don't want to debate the proper way to model a steelpush (or if those threads just feel way too intimidating), ask it here and I'll do my best to answer. If we run into a topic that could use a more in-depth discussion, we can spin it off into a new thread and I'll edit this original post to include a brief summary and a link.

So I designed this and it works beautifully (for me). But I'm looking for some ways to upgrade it, more realistic factors, etc. Does anyone have any ideas? (Also I made an SU about it, explaining an earlier edition).

I started reading the cosmere on the first year of my degree in physics and sociology, and after reading most of it (reading Edgedancer now, and missing Shadows of Silence and SP4), I looked at some of the spoiler streams and saw that someone asked about E=mc^2, and Brandon said that he didn't develop the math for this, since it would be to restricting, and that there were some problems, like how a sphere can emit light without losing energy. So, being a young eager physics student, I sat down and found solutions, for the sphere and for the restriction issue. Then... I developed these solutions. I found why Investiture acts at times like matter and at times like energy, how it causes effects in the Physical Realm, and what, assuming the solutions are turn, must be the structure of the Spiritual and Cognitive Realms. This allowed me to formulate a quantum description for Investiture and a General Relativity description for Realmatic Theory (which I think still needs some work). Anyway, I wanted to share this, so I wrote a paper called "A Quantum Description of Invesisutre". It's presumebly written in world, so no scientific names are there, though there are a lot of scientific terms. I used one side of the alethi caligrapher's script for some of the equations. Please tell me what you think, A Quantum Description of Investiture.pdf

Hi, I'm Kelsier's son, and I may have figured out the formula for Steelpushes and Ironpulls, but specifically Steelpushes. Allow me to explain. This is all assuming the Cosmere abides by the normal laws of physics. We know, thanks to Newton, that Force is equal to mass times acceleration, F = ma. Well, what's acceleration? It's the change in velocity (Vf - Vi)/t Thus, we get F = m((Vf - Vi)/t) Now, where would we get the velocity? Well, when Vin or Wax pushes on an object, it's giving it kinetic energy, whose formula is KE = (1/2)mV^2 Solving for V, we get sqrt(m/(2KE)) Now, this energy isn't coming from nowhere. I theorize that a certain gram amount of steel/iron has a certain amount of Potential Energy, what I call Metallic Potential Energy, whose formula I have derived to be MPE = bMt, where b is the burn rate (half burn, flaring, etc.), M is the energy at b = 1, and t is time. We can set the MPE equal to the KE, so that MPE = KE, which we can substitute their respective equations: bMt = (1/2)mV^2. Solving for V, sqrt(m/(2(bMt)). Now, we can take this velocity and plug it into the force equation from earlier Fs = m((sqrt(m/(2(bMt2) - sqrt(m/(2(bMt2) )/t2 -t1). This gives us the Average force from Time one to Time two. If we want the instantaneous force, we have to get a little advanced. Let's make Fs a function of time, Fs(t), where Fs(t) is our Force equation from earlier. Let's slap a Limit in there. Now, Fs(t) = m lim(t1->t2) ((sqrt(m/(2(bMt2) - sqrt(m/(2(bMt2) )/t2 -t1). Well, wait, that's a derivative. If we take advantage of that, and do a little bit of algebra, we get Fs(t) = t/(2sqrt(2bMt/m)) This my friends is my Theory of Steelpushes I hope this makes sense. If it doesn't, I understand. .

I was wondering something, I have always found the mecahnics of steel pushing somewhat vauge when I read, so I wanted to ask a couple questions. First, when you are burning steel you can see the blue lines, when you push on these lines does it take more steel? if not, can you just push on a ton of different objects to create a higher total net force out of a small amount of steel? Second, I have heard contradicting things on this, does the weight of the allomancer effect the strength of the push at all? if so does it just make the push stronger for the same amount of steel, or does it allow you to use more steel to push harder? Third, in the books it mentions that larger objects have larger lines pointing to them, and are easier to detect from further away, does this mean you can push harder on these large objects. At a longer range? and if so does this require a greater amount of steel, or does it just become more effeciant? Thank you!

So, I havn't found anything on this, so if there is already an answer out there please tell me. I was wondering about storing weight and the whole conservation of momentum thing. For example according to science, if you let yourself fall while being 200kg you would be falling with an incredible amount of energy (at terminal velocity (66m/s) it would be about 435600 joules), if you then suddenly stored your weight untill for example you were 10kg you would suddenly accelerate to 20 times your previous velocity (about 1320m/s) untill air resistance slowed you back down, but it does not really seem like the books emphasize this that much and I was wondering if anyone has an explenation? also as a fun thought, if that is how it works, an iron compounder+lashings could effectivly become a rocket, all they would have to do is make themselves like 10000kg then triple lash themselves in a direction and let themselves get to terminal velocity, they could then store weight until they weighed 1kg and go 10000 times faster (around 198000 m/s), and they can just heal from the damage casused by this with stormlight.

So we know that a Mistborn Era 1 year is shorter than a Mistborn Era 2 year. So if you're 20 in Era 1 you might be 17 in Era 2. Then what are the shortest and longest years on Worlds from your perception?

So Allomantic Iron allows a Metalborn to 'Pull' metals. So what if a Lurcher (or Mistborn) wore metal boots and pulled on them, would they be lifted up? Would this be a more effective, though more tricky, form of flight through Allomancy than using Allomantic Steel?

So could the Surges of Cohesion and/or Tension be used on liquids like water, or would that not work? And could they be used on gases as well? Thoughts?

So I've been reading Mistborn Era 2, and found a big problem with the bendalloy allomantic power. So the power is greatly increasing time flow in a bubble by burning the metal. I had no issues with that, until a scene where Wax falls out of one. He only describes a slight discomfort doing it. This makes no sense if you look at the actual physics of how that would work, and since Brandon and this community are generally interested in integrating "realistic" physics into these worlds with magic, I thought I would share my thoughts. So the biggest problem is that you should absolutely not want to move in or out of the time bubble. You might've heard of a phenomenon regarding black holes called "spaghettification". Since black holes have such a great gravitational pull, if any part of your body is closer to the singularity than another (which would always happen), you get stretched out by the differing pull on your, let's say feet, compared to your upper body. Essentially, by moving out of the bubble, a reverse spaghettification effect would happen to you. Since time flows slower on the outside, the part of you out of the bubble would also move much slower, while the part of you inside much faster. I think this would compress your body to an extreme degree, maiming, or in the worst case, killing you in the process. What are your thoughts on this? I just wanted to share my opinion, because it nagged at me. I'm not very far into the books, so there might be an explanation for it later on. If so, hit me with a RAFO

Watching the newest WoB shardcast made it apparent to me that there differing views on Shard/Planet Interaction. I want to get people's opinion on how I view it. I would post some of the WoBs supporting but I'm new and can't do links. WOB: asmodeus You've said before that a lot of the magics we see across the cosmere come from an interaction of Shards and their Investiture with the planets they Invest in. What does this mean practically? If Scadrial explodes tomorrow, will Hemalurgy stop working across the cosmere? Brandon Sanderson Hemalurgy wouldn't stop working, most likely, but it could. There are ways that you could make it stop working. I kind of mean that the Shards are an innate part of physics in the cosmere, and the magics that arise are an innate part of physics because of that. Like atium seeped out into the Pits of Hathsin, in the same way, these magics are just gonna leak out, and different places are going to affect them. You'll see Lightweaving happening in different places, and the way the Shard is interacting with the local... The way the Shard is is going to affect how Lightweaving is administrated in the various magics, but it's still gonna be there. Hemalurgy is kind of a similar thing to that. You will see Midnight Essence, you will see some of these recurring ideas popping up, and these are like natural parts of the physics, but they're influenced by the Shards on the local planets. I don't know if that answer, that's gonna be a really fun one for them to transcribe into the Q&A thing, because I go around in circles on that question a ton. Put this part in when you do it. Footnote: It was a really fun one. YouTube Spoiler Stream 4 (June 16, 2022) Other Known things: Rosharan Magics Ashyn Uses similar surges as the Rosharan magic system does today. The magic is now sickness based. The magic was not always sickness based. All of the rosharan system was specifically set up by adonalsium for a specific purpose. Shards can have investiture in parts of the cosmere that they are unaware of until they look for it. When aware of it, they can shape it in a way. "Shards influence and tweak certain Investiture, giving it a kind of spin or magnetism, but all Investiture ever predates the Shattering--and in the cosmere matter, energy, and Investiture are one thing" Scadrial was created by Ruin and Preservation but they didn't create the atoms themselves. My Interpretation: I think my interpretation is much like Argent's was in the recent WoB video, but I don't think he had all of the main points readily available to push this idea forward. While I don't think it's totally accurate, I think it helps understanding to think of all investiture and magic as particles for the sake of this. In any given spot you may have matter, light, gravity, magnetism, electric charge, magic (such as midnight essence or lightweaving particles), ect. With these raw materials from a location, magic systems are formed. I would liken it to how different communities would use stone vs wood vs clay as base building materials for their civilizations based on the materials available and the weather forces they see regularly, except on a galactic scale. While typically not cognizant, the shards (either the power or the vessel or a mix of the two) bring magic systems into being based on what is available in that vicinity and how those magics interplay with the shard. It may be possible for a shard to intentionally bring more materials to in area to allow a specific interaction between themselves and the materials to come forward, but probably don't do things more than that to create a magic system. For Roshar, we know that Adonalsium created the entire system for a specific purpose. While we don't know what that purpose is or how it works, if we think of the system as a singular thing it would make sense that the system has a specific set of raw materials. If all investure is just a part of physics then these magics would be part of the raw materials of the system. That may explain why pre-sickness Ashyn, post-sickness Ashyn, and Roshar all powers relating to those surges. There's something about the area that makes those magics more prevalent. I think it would explain it better than the surges are of Honor/Cultivation. That would mean that Honor/Cultivation had a hand in the creation of the unchecked surgebinding that destroyed Ashyn, and then also mimicking/forbidding it on Roshar. We know that Ruin and Preservation very intentionally made Scadrial by jointly gathering and arranging atoms in a way that subfused every atom with thier... attunement? We know that Lord Ruler and Fuzz at times have tweaked the world to have the magics play in their favor (creating mistwraiths, forming the Pits, or changing the metals used to include Atium). But it makes sense that it would be outside of their abilities to have it be "if you burn iron you can now lightweave", because lightweaving particles don't seem to be one of the materials that are readily available in that system. One of the talking points in the stream was that it could be inherent to the shard and that endowment would likely do breaths wherever she was, but that breaths may look different. I would agree with this based on this model. The breath, the magic endowed to each person at birth and the possibility to come back and be endowed with extra life, is likely an effect of how that shard's essence interplays with the materials around it. We may think of Nalthis as a place with a lot of the magic particles that power Tin at scadrial, and other magic particles that can bring awareness/ect for awakening. If endowment was instead on a planet with a lot of gravitation surge and connection surge maybe instead your breaths would help you fly and you could use them to forge a connection between things, but the mechanic of being born with a little and being able to pass them around would likely stay. Let me know what you think. Feel free to add ideas if you think you can support it or bring up some counter arguments. I just was listening to the podcast and I couldn't help but feel the ideas weren't fully fleshed out when Argent was talking about it, and it didn't sound like the other people that disagreed were necessarily disagreeing with the key points. Thanks all!

Uhh... where did we leave off? Dyson Sphere... system-wide production... extensive use of all immediately available resources... Gotcha. Kay. We're back. Stellar Engine! Left y'all hanging on that. It's a real piece of work, taking the power of a dyson sphere to do the unimaginable: Move the solar system. All the planets, asteroids, and stuff in our system are tidally-locked to our star: "the Sun" (as it is rather uncreatively named). Therefore, by moving the Sun, you can move the entire solar system. How would we do this? Good question. The nitty-gritty engineering bits are all pretty foreign to me (check out Kurzgesagt's video if you're interested), but essentially you just need to make a massive booster using the Dyson Sphere as an engine. You plug it into the sun and fire it up, scooching our solar system along at a few thousand kilometers per hour or something. The main reasons we would want to accomplish such a thing would be to avoid potential interstellar threats, like rogue stars and planets kareening into our solar system and throwing everything around like a furious toddler. Such threats would be apparent to us for thousands of years in advance, giving us plenty of time to move the solar system successfully out of the way. Bear in mind, of course, a rather important thing: the solar system is heavy. While we'd be moving pretty fast compared to your old prius, this would be absolutely nothing on the scale of galaxies. Such movements would still be sufficient over long periods of time, as evidenced by space maneuvers used on smaller scales in real life currently (for example, one of the primary ways we move around satellites is by the use of mirrors. The minute amount of energy light puts into these things are enough to slightly change the movements of the satellites, which over the vast span between planetary bodies is all we really need). Some concerns, addressed: But Faaaadrannnnnn, what happens if Earth swings around to where the engine is shooting its propulsion stuff? Relax. We're not stupid. The engine would be facing downwards in relation to our orbit around the sun. But if it's facing downwards, then wouldn't we push ourselves out of the solar system? First of all, you're really overestimating the overall power of this device, and second of all... no, actually! Our solar system is actually facing closer to perpendicular our galaxy's plane than parallel to it. The exact number is close to 60 degrees, I believe. So the engine would be blasting us more or less along the same plane. Would this even get us anywhere??? No. It would not. Reminder: this is useful for minute changes in our solar system's placement for long-predicted threats. This wouldn't be any useful in a space battle or overall travel. If this sucker's moving at 20 m/s, it would take a million years to move 0.003 light-years. Proxima Centauri, our closest star, is 4.246 light years away. Crunching the numbers shows that it would take such an engine 1.415 billion years in order to get our system over there. And also putting a solar system inside another solar system would be really stupid. So, at the end of the day, while Stellar Engines are cool, they aren't exactly great. We need some real speed if we're going to be traveling from star to star, colonizing distant planets and meeting friendly aliens. Which means now we're getting to the real numbers. Sub-lightspeed This isn't anything new. We go at less than the speed of light all the time! Such is perfectly normal behavior for literally anything that we can consider to be a "thing." The laws of physics dictate that in order to get things moving, you have to impart energy into it. Therefore, in order to make something go fast, you need a lot of energy. Good thing we got a lot of energy, then. Currently, the fastest human-controlled things are little neutrons and such, shooting about through massive particle accelerators to do... things, apparently (depends on how much of a conspiracy theorist you are)--and they go FAST. The numbers say they go at 99.9999991% the speed of light, then collide into each other to create MINI BLACK HOLES (depending, also, on how much of a conspiracy theorist you are). This is proof enough that it is within the boundaries of our current knowledge and technology to achieve such speeds, meaning that it's possible that we could do the same with larger objects. Of course, it's not really that simple. Protons are really small and really light, so accelerating them to lightspeed is kind of a cinch. There was literally a boy scout who made a working one for his Eagle Scout project. When we kick up the mass a bit, though, things get more finnicky. In order to understand this, you have to look at the fundamental laws of physics. The speed of light (or "C", as you might know from the famous equation E=MC^2) denotes the finite and immutable constant of a massless particle. A photon is the single smallest amount of energy you could possibly have: it is, essentially, your perfect "1" for the ultimate calculus of the universe. Therefore, if C is the speed it goes, then C is the fastest anything can go. Ever. Which, of course, is a problem. We can look at energy in another way, though, in its kinetic form: force. F=MA is Force equals Mass times Acceleration. If acceleration is C, then to move anything of literally any mass ever (let's say one kilogram. We'll be using SI units, as C is defined by the meter). Force would equal 1 X C, meaning you would have to have almost three hundred million joules of energy. To move your car at the speed of light, you'd need about 390 billion joules of force. To get your massive party bus going that fast, it comes out to almost 5500000000000 joules. So you can see now just how ludicrous that is. For comparison, the average annual consumption of energy on Earth is... uhh... let's see... 580 million trillion joules... so to get your bus going that fast you'd need about 1/100th of the annual energy consumption... Uh. wait. Hang on. That's global consumption, but by now we've colonized the entire solar system; not to mention the Dyson Sphere. It's ludicrous still, but... Hold up. Are you telling me that this is actually doable??? Alright, it'd take a LOT of energy to get your spaceship going at close to the speed of light--but by this point in time we'll have increased energy production and consumption by several factors. We've nearly tripled energy consumption since the industrial revolution, which was again triple the amount than humanity in late agricultural periods, which was again about triple(ish) the amount used in early agricultural periods. That said, interstellar travel would be to a system-wide species as regular space travel is to us now. It would be incredibly expensive, but still doable. You'd likely have private investors and crazy gazillionaires funding private scientific and exploratory missions into the closest star systems. Such journeys would be decently long, spanning between five and twenty years. It's possible that by now humanity's life expectancy and quality would've drastically increased, so such time spans would be feel shorter comparatively; however, they'd still be incredibly long and arduous missions. Voyagers would have to take large amounts of supplies and perhaps live in more luxurious ships than what average planetgoers would usually use in order to maintain their mental states. The Speed of Light This is a problem. You see, Einstein was at it again with his massive breakthroughs, learning about things like the fundamentals of space and time--y'know. The usual. I imagine he was driving a car when he came up with the idea of General Relativity: the basic philosophy of frames of reference and such. Let's say he was going at 60 mph on the local highway, then passed an older bloke going only 50. To the police officer watching for speeders from the side of the road, they are going 50 and 60 miles per hour, as he watches them pass. His frame of reference has, effectively, a speed of 0. Einstein's car is going at a speed of 60 (gosh, miles; what have I done to myself?). However, he isn't constantly observing the speed of his car, as he is moving with it. Therefore, from Einstein's frame of refence, his speed is 0. That means to him, the old bloke is going at a speed of -10; the officer, -60. To the old bloke, Einstein is going at 10 mph, and the officer -50. And then he crashes into the median because he'd forgotten something his mother had taught him ages ago: don't math and drive. Of course, it's a lot messier in reality. The easy maths work well if you can't observe your own speed, which is a hard thing to do if you're rolling across a bumpy road during rush hour. The numbers would work better if there wasn't any resistance or external things to observe (like the Carmax ads or bridge overhead). If, say, Einstein was in a spaceship going through the cold vacuum of nothing--no friction, no gravity, no nothing--then these numbers work a lot better. Still, the concept remains. Now we get into special relativity, which is a wonderful can of worms that I will gladly open here. Let's say Einstein drags himself out the burning wreckage of what was once his faithful prius and decides to take the trolley home instead. As he arrives at the station, though, it's just pulling out, forcing him to wait for the next one. Annoyed, Einstein watches all the happy passengers rolling out towards their destination through the window. First, he observes Passenger One: a small child bouncing his toy up and down. To the boy, he's dropping the ball one meter down, and then the ball bounces one meter back up. Because he and the ball are moving with the trolley, he only observes two meters of overall movement. However, to Einsten, he also observes the moving trolley. In the time it takes the boy to bounce his ball, the trolley also moves a meter away from its previous position. So while the boy observes a basic up-and-down, Einstein observes an angled down followed by an angled up, creating a sort of triangle. One meter up, one meter down, and one meter across: therefore, Einstein observes three meters of movement. This is what general relatively says. We already went over this. Moving on. Second of all, Einstein observes someone turn on the overhead lights to read the morning paper. However, the light reflects off the floor into the man's eyes, blinding him and making his spill his coffee everywhere. To the man, the light moved one meter down and one meter up (simplified, because I felt like it), meaning it moved two meters at a speed of yes. On Einstein's end, however, he saw it move three meters along with the trolley. Here's where the problem is. For the ball, the maths are simple. Speed is equal to distance over time: the distance was different, the time was the same - therefore, the only difference between the boy's and Einstein's observations was the speed. This makes sense, because the boy wasn't observing the additional motion of the trolley, but Einstein was. S = 2/1 for the boy, and S = 3/1 for Einstein. But light has a constant speed. Always. ALWAYS. We don't actually know why this is, but it is THE RULE. That means that we can't apply the rules of general relativity to the man who used to have a coffee and Einstein. If we did, then S = 2/[fast] for the man, and S = 3/[fast] for Einstein... this would mean a difference in speed, which is totally not okay. Something that we also can't dispute is the distance covered, because the distance isn't a constant or randomly variable in any way. They have to remain at what each of them saw, or the law of general relativity wouldn't hold up, and suddenly traveling by car would get a whole lot weirder. This, of course, leaves us with one thing we're allowed to mess around with: Time. If the distance is x and lightspeed is the constant, then time is the variable. Let's put Einstein back in his brand-new, top-of-the-line Prius Spaceship, then send him for a joyride out into the cold heart of space. As he passes other, inferior spaceshippers along the space highway, he observes them at varying speeds due to the law of general relativity. However, he also observes light from his headlights shooting forwards at their own speed: the speed - you guessed it - of light. The way to conceptualize it is to remind yourself that frames of reference don't need to be human or animal or even alive at all. Literally everything is its own frame of reference: your shoe, your shoebox, the shoe store... even the old shoes left in your closet from years ago! This means that Einsten is in his frame of reference; the space prius is in its frame of reference; and the photons shot out from his headlights are their own frame of reference. What are the implications of this? Well, remember that light has its constant speed of roughly 300 million m/s, and from EVERY frame of reference, it must be going at this speed. That means that for Einstein, who is going at a speed of... let's say 500k m/s (it's a good prius and also in space), he sees the light shoot out from his car towards the rapidly-approaching Space Starbucks at 300m meters in a second. However, for the space highway cop waiting for something to actually happen, he sees the light go at 300m meters in a second... PLUS 500k meters. The difference in apparent spacialities is due to general relativity, as I explained earlier. Remember that Einstein is observing the rest of the universe moving towards and then zipping by him at the speed of his prius due to his frame of reference, while the cop is observing Einstein zip by at the speed of his prius from his own. That means when Einstein sees the light, he's seeing it move at 300m m/s away from him as apparent from his own reference frame of 0; while the cop observes light moving at this speed, but already effectively "pushed" by the prius's speed of 500k m/s. Now there's only one thing left to do: plug in the numbers and see how much time got dilated. speed = distance / time. Distance covered for Einsten going to be 300m, as he observed over the course of one second. The speed of light, of course, is constant, meaning we can plug that in right away. 300m/s = 300m / x. 300m/s (x) = 300m - > x = 300m / 300 m/s. x = 1. Easy. Now for the cop. He saw a distance of 300500000. 300000000 m/s = 300500000m / x. Do all the same stuff as above and you find a brand-new number: 1.006666666...7 So at a speed of 500k m/s, Einstein is experiencing time 1.007 times faster than a person sitting still and doing nothing. Time travel is real, guys. And we're doing it all the time.

Throughout the series of Era 1, the ash is described as black: "The dry plants, the angry sun, the smoky-black sky." -Kelsier, Chpt. 12, TFE "the black flakes covered up everything beneath," Chpt. 61 and 63, HoA I absolutely love Sanderson's world building and the scenes he creates; it makes sense from an emotional point of view that things need to look dark and depressing. But the Lord Ruler should've known that black colored ash would absorb sunlight and heat up the planet more. White/reflective would've been more appropriate, though snow-like-covered landscapes might not bring as dreary a picture to mind. Perhaps gray would've been a good compromise.

I believe that the behavior of different Lights, their combinations and anti-Lights can be easily described using simple physics analogies. Shardic Intents are pure states, that, like quantum states, can be added together in any proportions, creating custom Intents / Rhythms. The easiest examples are Investitures of two different Shards mixed in 50%-50% proportions e.g. Harmony (ettmetal) = Ruin + Preservation, War (Warlight) = Honor + Odium, Science (Towerlight) = Honor + Cultivation Rosharan spren are different mixes of X% Honor + Y% Cultivation, where X and Y add up to 100. This would, fortunately, make creating custom anti-Lights rather difficult. Anti-Lights are Investitures of opposing Intents, for example Ruin and Preservation. As Odium seems to lack a directly opposing Shard, anti-Voidlight is some combination of other Intents that doesn't occur naturally. I would assume some mix of Honor, Devotion and maybe Dominion (since they share the Unity theme) and maybe others, mixed in the exact proportions that create the Rhythm exactly opposing that of Odium. With this assumption, two planets of Cosmere (Scadrial and Roshar) correspond nicely to the behavior of two types of hadron particles: mesons and baryons. Mesons are built from a quark and an anti-quark and are inherently unstable. Ruin and Preservation's Investitures being their own anti-Investitures explains a lot: the explosion of power that kills Vin and Ati, Ati being unable to splinter Preservation to Khriss' confusion, mists avoiding hemalurgic spikes. Ettmetal exists only because both powers are held by one individual, and, as mesons, is extremely unstable. Baryons are made of three quarks, so neither can each other's anti-quark. They are bound together in a way that makes them confined together: pulling one quark would require more and more power the further you take it from the particle. It is exactly the same behavior that seems to bind Odium to Braize and H&C to Roshar, the latter described exactly by Mraize in his talk with Shallan

Okay, I really should be doing my homework, but I just finished Dawnshard, boi oh boi, was it a good time. Anyway, I am a physics student, and have been thinking quite a bit about what Nikli said during the deal with Rysn. He said, "The most powerful forms of Surgebinding transcend traditional mortal understanding... All their greatest applications require Intent and Command. Demands on a level no person could ever manage alone. To make such Commands, one must have the reasoning--the breadth of understanding-- of a deity. And so, the Dawnshards. The four primal Commands that created all things" (pg189,190). He goes on to say that the Commands were used to undo Adonalsium, but what I am interested in is his what he said about the four primal commands. I've seen a lot already of people talking about how these relate to the Intents of the shards, but I have not yet seen how anyone has talked about how these may relate to the four fundamental interactions we know and love as the Strong nuclear force Holds together atomic nuclei Weak nuclear force Is responsible for radioactive decay Gravity The curvature of spacetime due to mass/energy Electromagnetism Responsible for much more than you might think, like light and chemistry The reason I connect these to the four commands is because Nikli implies that the Dawnshards allow one to surgebind at the most primal level. We already understand that surgebinding is the ability to manipulate one of the ten surges or what Rosharans perceive as the ten fundamental forces of physics. Basically, the reason there are ten surges is because everyone kind of agrees that it looks like there are ten, though there are actually only four interactions. These four fundamental interactions govern how literally everything in the universe is structured, behaves, etc. Thus, the dawnshards are the ultimate surgebinding tool that allow one to plug their will (Intent) directly into one of the four fundamental interactions (Commands) of the universe. There probably is some sort of relation to the Shards and their Intents, but I think the Dawnshards are primarily a god tier tool that allow people to directly influence the world without going through a Shard. What are your thoughts?

This post is the consequence of the most recent chapter epigraph about how the metal "conducts" stormlight, but it took a bit of a left turn and I actually barely theorize about what that metal might be. It is also sort of an extension of a comment I posted almost three months ago. If you're interested, here it is: (Although I will be reiterating most of the information there, so it is not necessary for you to read first) In this comment, I provided a theory about how and why stormlight moves in terms of changes in potential energy. To be clear here, the potential energy I refer to is not the energy of the investure that makes up the stormlight, but rather the potential energy of the stormlight's position in the environment. For example, if you put an infused sphere at the top of Urithiru, it would have a lot more potential energy than the same sphere at ground level. This potential energy is due to the sphere's ability to drop, not because of the amount of stormlight it contains. Without any barriers, any system will tend towards having the lowest potential energy. Balls will roll downhill. Stormlight will move from positions of higher potential energy to positions of lower energy. In addition to differences in potential energy, we need to talk about "activation energy" here, which is a concept from chemical kinetics. Basically, activation energy acts as a barrier to a process. Rather than determining whether a process will happen*, it determines how quickly it will happen. (*Note: if you make the barrier high enough, you can stop something from happening by making it ridiculously slow). This barrier is the reason why the processes I describe will not happen instantaneously. So, here's my energy diagram for stormlight: Here are my justifications for the features of this diagram: All stormlight eventually returns to a free, gaseous state not held in any object. However, that does not guarantee that it is the lowest energy state. If it behaves like water in the water cycle, then it could "evaporate" despite the fact that this process increases energy. I have no true evidence that stormlight is lower in energy at a free state than when it is in a gemstone, but this is the simplest placement. You could place it between "Gemstone (Small)" and "Radiant" without really changing this thoery, although small adjustments would have to be made. Large gemstones leak stormlight slowly, so there is a large barrier which slows down this process. Small gemstones leak more quickly, so the barrier for this process is smaller. Stormlight will automatically transfer from a smaller gemstone to nearby larger gemstones during the process of trapping a spren. This process is spontaneous, so the potential energy of stormlight in a large gemstone is lower than that in a high gemstone. EDIT: I don't know why I didn't think of this sooner. Perhaps the best explanation for why larger gemstones are lower energy has to do with the "concentration" of stormlight. It's very possible that the energy density of stormlight in a fully charged small gemstone and large gemstone are equal. The same quantity of stormlight in a smaller gemstone, however, occupies less volume. Thus, when given the opportunity it will "diffuse" to a larger empty gemstone where it takes up more volume. Basically, the potential energy of stormlight in a gemstone increases as the concentration does. This is more in line with the description of stormlight as moving along a pressure gradient, since this is how pressure works in gasses. If you have gas in a small container and you allow it to move to a larger one, it will diffuse between the two. The only difference is that it would leave some gas in the small container. Don't know if that happens for stormlight. Features of gemstones such as their cut determine the size of the barriers, but not the energy of stormlight within the gemstone. Stormlight is at a higher energy when held by a Radiant than when held by a gemstone. I know this because when Kaladin swears the third oath, stormlight entering him from nearby gems causes the air to grow cold and form frost. This means the process consumed energy. Objects other than Radiants and gemstones are even higher in energy. We know this because when Szeth or Kaladin infuse an object with a lot of stormlight, the object grows cold and forms frost. Again, this is a consequence of energy being consumed. (That is what the arrows saying "endothermic" in my diagram mean). A really common demonstration in chemistry classes is to perform an endothermic reaction in a beaker above a block of wood, with some water in between. The water will freeze, binding the beaker to the wood. High-investure conditions refers to states such as Honor's perpendicularity, from which stormlight will burst out and fill gemstones. So far, this is identical to the theory in my much earlier comment, except with the additional evidence of the frost-formation, which I didn't think of three months ago. Now, you can probably see how the conductive metal does its thing according to this theory—it reduces the energy barrier between a Radiant and a gemstone, therefore facilitating this transfer quickly. This is the point where I decided to focus too much on the word "conducting" and went off the rails by drawing circuits. (Disclaimer: I am a chemistry student, so I'm pretty well versed with thermodynamics but am less confident with circuits. Please help me out if you actually know circuits super well) So, how do circuits relate to thermodynamics? Well, the driving force behind the current in any circuit is a difference in potential energy of electrons at the beginning of a circuit versus the end of a circuit. In this analogy, I well be relating the movement of stormlight to the current. (And yes, I'm using positive current. Despite the fact electrons flow the other way. Maybe that's dumb, go ahead and flip all the signs if you wish). Stored stormlight will be represented as stored charge—a capacitor! Here is where things get a bit tricky though. A capacitor, in the simplest case, consists of two parallel sheets of metal which each store opposing electric charge. The capacitor will fill with charge when it is connected to a battery, and without a battery it will act as a source of charge and produce a current in a closed circuit. Now, in order for this to work with stormlight I had to make some... adjustments. The object holding the stormlight cannot really be represented by the capacitor itself, but rather by one of the sheets of the capacitor. The other sheet of the capacitor represents the object that the stormlight is flowing to or from. As I switch between different processes, I will be switching these sheets out. Which is not really a thing that happens in circuits. It felt weird. (I think there might be an easier way to do this that has to do with something called "ground" but uhhh as I said I'm not too well versed at this so any electrical engineers please help). (Also, for those unfamiliar with circuit notation: a capacitor is two parallel lines of equal length. A battery is two parallel lines of unequal length. Resistors will be zig-zags). Let's apply this to the simplest case: stormlight being held in a gemstone. The infused gemstone acts like a positively charged plate in a capacitor. Freedom represents the negatively charged plate. Stormlight, represented as current, which flows from the positive plate to the negative plate, escapes the gemstone. The barrier to this process is represented by a resistor, which slows the transfer down. In this case, the resistance is very high and the transfer takes a long time (days). Next, we can look at the process of a Radiant drawing in stormlight from a gemstone. This is an endothermic process (it increases energy) so energy must be supplied to facilitate it. In this case, the Radiant has the power to act as a battery: On the left is the initial state. On the right is the final state. This is also the first example of the weirdness that was a consequence of using capacitor plates to represent objects. Why is the gemstone, which begins infused, initially uncharged? Well, if I had given it a positive charge, the battery (Radiant) wouldn't have been needed to drive the flow of current. In order to represent the fact that the gemstone is lower in energy than the Radiant, despite containing stormlight, I had to make the plate begin as uncharged. Afterwards, the Radiant will look like this: Basically, the same as with an infused gemstone. The only difference here is that the resistance is much lower, allowing current to flow faster (the stormlight leaks faster). When a Radiant gets stabbed by one of those special conductive Fused spears, the resistance essentially disappears: Thus, current (stormlight) flows very quickly from the positive plate (Radiant) to the negative plate (gemstone). When a Windrunner like Kaladin infuses an object with stormlight, the process looks very similar to when the Radiant draws stormlight from a gemstone. The Windrunner acts as a battery and transfers stormlight from lower energy to higher energy. (Okay these are the last ones I promise) What happens after the object is infused? There are two subtly different possibilities that involve circuits, and one which doesn't: The first possibility is that, as the stormlight leaves the object, some of the potential energy that it is releasing is converted into the effect of the surge. At first, this option seems to be the most appealing because it is how stuff gets powered in real-life electrical circuits. (like lightbulbs) (by the way, this process also involves some resistance so it doesn't happen all at once) However, there's a bit of an issue here. If the surge is produced by stormlight leaving the object, the an object like a gemstone, which has a much higher "resistance" and thus slower stormlight loss, should exhibit the surge less strongly. Since this is not the case, I believe the second possibility is more accurate: that there is a small amount of resistance which leads to the object losing stormlight quickly, and that the effect of the surge is maintained as long as there is stormlight left in the object. The third explanation kind of defies circuits and it is that stormlight is actually consumed to produce the surge. Since current is never consumed when an electrical circuit, I couldn't figure out a way to represent that. This is also the reason why I haven't represented stormlight healing or surges such as Soulcasting or Progression, which appear to consume stormlight. The same conundrum applies to fabrials: do they consume the stormlight, or do they consume potential energy as the stormlight escapes them? Anyway, thank you to anybody who actually read this whole thing. Wow. You're almost as crazy as I am for writing this. For those who didn't, I totally understand. Although I can't quite come up with a good TL;DR. I might include that later. (Edit: wow a lot of the formatting here is wonky. There's extra blank lines and weird indents all over the place)

---- Main topic here! Download the current demo here! Imagine you're a Mistborn in Luthadel and you're jumping over rooftops through the mists. That's what this game project is. It's 100% spoiler free if you're familiar with the basic allomantic powers. I'm a student at Future Games in Stockholm, and this is a pet project I'm working on between classes. I'm working in Unreal Engine 4 and its Blueprint visual coding system. I started this a couple of months ago when I was just done with the Hero of Ages and really into the allomancy magic system. The goal of this project is to make an FPS-style Mistborn game, where you can play around with some schmexy allomancy. It's not finished, and probably won't be for a while. However! I'm updating the demo as I go along, so you can see where it's going. What's in it? Currently, it's a playground with the physical powers (steel, iron, pewter and tin), set in Skaa areas of Luthadel by the wall. There are a couple of NPCs (some friends, some not), a koloss, the fabulous mist, coins, vials and plates. There are some tutorial signs posted in the level to help you control your powers. Read the main topic (linked above) to get specifics about the content. What's coming? The mental powers, a progression system, levels and storyline. It'll take a while, but I'm going at it when school's not overwhelming! What now? I dunno! Go play it and tell me what you think!

-> Download Version 0.10 here! <- Hey, y'all! First thread on this forum. I'm a student at Future Games in Stockholm, and this is a pet project I'm working on between classes. I'm working in Unreal Engine 4 and its Blueprint visual coding system. I started this a couple of months ago when I was just done with the Hero of Ages and really into the allomancy magic system. I'm currently on Shadow of Self. No plot spoilers! Goal The goal of this project is to make an FPS-style Mistborn game, where you can play around with some schmexy allomancy. As a fan-made game, this will stay free-to-play. Caveat I want to make a good game representation of the Mistborn books, but some things are blocking the way. School. My time is spontaneously devoted to this project. Me. I'm not the most passionate die-hard fan, I just like the idea of a properly made game, as in true to the material. Controls. I want that feeling of being a cool Mistborn, jumping through the mists, throwing things around. But. Computer/console controls are severely limiting to a magical power that should take your whole body to control (Yeah, who knew, huh?). I want the player to have a good time, regardless of having read the books or not, so I will keep controls from being overly complicated. More advanced moves from the books will probably not be possible, so I will focus on making the general moves feel really cool and make sense for the player. Current features These are the features that I have right now. These will be updated as I go along. The most recent additions are in bold.

Note: This is written from an unbiased, nonreligious standpoint using the assumption that if something cannot be proven it should not be used in science. So, fi you religiously disagree with this, my apologies. Free will is not, in fact, real. Our brains are simply chemical cocktails getting bombarded with electrical stimuli caused by an utterly random formation of our bodies in a perpetuating form, that became a pattern. When something happens, it sends stimuli to our minds, which causes those balls of matter to send a different signal which causes our bodies to move in a certain way. It is actually utterly random, and we do not control it. In fact, the entire universe is just bouncing particles, and we have just become, this. A different element you might consult is the probability illusion. Probability is an illusion. As in, even if we were to say, "There's a ninety percent chance of object A getting hit by object B, instead of object C," and had statistics and science to back it up, and object C hit object A, then there was never any chance of object B being the thing to hit it. This relates because our brains work like that, but infinitely more complex. We are receiving constant stimuli which is causing constant response. In truth, if you think about it, death is simply a total lack of stimuli. On the bright side, this proves the scientific necromancy would actually be possible once we understand how the mind works, we can start the stimuli reaction again.

I've released another major update - see here! Original post: I haven't posted in this subforum before, so I thought I'd mention it here. I've been working on a game/physics demonstration that implements the physics of Allomancy. You can find a longer description (and a lot more pictures and videos) at the full post here: Let me know what you think!

Update 1.2.1 – The Zinc Peripheral In Invested 1.2.1, the sphere's had a zinc peripheral installed, letting it use feruchemical zinc to increase its processing speed and slow down time. This makes it easier to fire coins while flying and select targets for Pushing and Pulling in the heat of the moment. See the changelog for all changes, but here's one in particular: you don't have to select targets before Pushing or Pulling on them. Trying to Push with no targets selected will Push on whatever metal you're looking at (dubbed "vacuous" Push/Pulling). This means you can fly around Luthadel without touching the keyboard. Since some of the controls have changed, be sure to check the in-game Help Overlay as a refresher. Next step: Means of quickly choosing different methods of controlling Pushes and Pulls. One of these will be a method for Pushing on all targets in a general direction, which Wax does a lot in the books. Another is the famous steel bubble. If math gets anyone excited, here's the fun differential equation I wrote for the intensity of the visual effect during zinc time. Fiddle with the variables and try to figure out what they're for, 'cause I ain't telling. X-axis is percentage of zinc remaining in the bank, and y-axis is intensity. Hope everyone's having a good summer. As always, let me know your thoughts. Update 1.2 Last year, I began working on a game/simulation implementing the magic system of Allomancy. I made a thread several months ago to document the initial state of the game and discuss different ways to mathematically model Pushing and Pulling. I establish a lot of the physics of the game there, so I recommend you read it if you haven't already. I've worked on the project a lot over the past few months. This post will be separated into three main sections: the first, focusing on the physics; the second, focusing on the game (with an interlude for more physics); and my plans for the future. Here is the second update on the progress of Invested. The Physics In Pagerunner's famous thread, I made several simulations comparing different models of Pushing and Pulling, showing off how Pushing duels could work as well as what happens when the coin you're Pushing suddenly hits a solid wall/ground. Those simulations can be all viewed in-game, so feel free to examine them yourself and experiment with the Allomancy settings. If we assume anchors do nothing special for your Pushes, Allomancy behaves like an undamped spring. If you push off of a coin into the air, you'll oscillate up to your max height, then fall all the way back down to the ground, then back up, and so on. Changing the relationship between distance and strength doesn’t change the behavior of the system. Pushing duels work in a similar way. The 10 cubes are allomancers, anchored to the ground. Without any dampening, you get a boring spring. The only model I could find that solved both of these problems was the infamous theory that the strength of Pushes is a function of velocity. In case you haven't been following those conversations, this theory (in its most basic form) claims "the higher the relative velocity between the Allomancer and target, the weaker the Allomantic force." Pushes on anchored coins will be stronger than Pushes on unanchored coins because anchored coins are completely stationary (that is, the relative velocity between the Allomancer and target is much smaller). The flavor of this theory that works best in the game (in my opinion) reverses the effect when the relative velocity is negative, i.e. when the Allomancer and target are moving towards each other. This means that Pushes on targets flying towards you are even more stronger than Pushes on targets flying away from you. When you're falling and throw a coin down, your Push will be weak until the coin hits the ground. Then, your relative velocity will be negative, and the Allomantic force will increase significantly, giving you a "jolt" as soon as the coin hits. This is the effect we see in the books, so it's what I have enabled by default in the game. With this model, Allomancers stabilize near their maximum height, rather than oscillate about it: Changing the constant used in the calculation of this velocity factor makes the system more critically/under-damped: Watch how duels play out. I've also unanchored the Allomancers, and this looks a lot more like how I envision Pushing duels in the books. The strength of the Allomancer is important, but weight determines who will move in the end. Again, you can experiment with these settings at any moment. The Game The player is a "primer sphere" - an Allomechanical construct or fabrial. It is an experimental device designed to test the limits of Scadrian magic. The sphere's mechanical nature gives it full control of its body and moment, allowing it to roll across surfaces and jump. This is enhanced by the first metal the sphere can burn: pewter. This is used for sprinting and pewter-jumping. By passively burning pewter, the sphere exerts a greater force while moving, allowing it to better anchor itself or move while Pushing and Pulling. While burning pewter and jumping, the sphere jumps further in that direction and can jump off or up walls or kick away small objects. Secondly, the primer sphere can burn iron and steel. Passively burning either of these metals reveals all nearby sources of metals. The wider the line, the heavier the source. The brighter the line, the stronger the potential Push on that metal. The sphere can "Pull-target" and "Push-target" one or more metals at once. When a metal is Pull-targeted, it can be Pulled on - likewise for Push-targets and Pushing. (Interlude: physics) After all the calculations are done, the player has some Allomantic Force they exert on the target. The mass of iron or steel burned is directly proportional to the net force they exert. If you're pushing with 1000N of force, you're burning 1000mg, or 1g, of iron every second. There's actually a WoB that mildly contradicts this: according to Brandon, metal burning speed is proportional to power drawn, not force. There are two reasons for why I make burn rate proportional to force. First, I can't be sure if Brandon is talking about "power" with the definition used in physics (i.e. a change in energy over time). If not, then there's nothing to worry about; the novels are wobbly enough to not be sure how precisely metals are burned. Still, in the future, I might shift things around to have all calculations work around power/energy rather than force, but the former is harder to calculate than the latter. My college-level textbook only talks about power in regards to applying a force to an object such that it moves at a constant velocity, so the math would get… difficult. I'm working on a model called "Distributed Power" based off of Pagerunner's model 3 that does something similar to this, but it's a work in progress. The main difference between force and power (in this context) is that power is a function of velocity; but, if we're using the Exponential with Velocity model, force still changes with velocity, just with a different relationship. There's potential for a fair bit of discussion in regards to this. The second, more important reason for making burn rate a function of force is reduce obfuscation - if you're consistently Pushing with 1000N, you know you're losing exactly 1g of steel every second. If you have only 10g of steel left, your intelligent lizard brain can figure out how long you can keep up that push. This relationship is more intuitive for the player, and changing this to power would lose that clarity. (end interlude) It wouldn't be Mistborn if you couldn't throw coins. You can toss coins. If you Push while doing this, you'll fire coins directly towards the crosshair. Holding "jump" while tossing a coin will throw it downward, useful for cruising above the ground or a smooth landing. There's also a "Coinshot mode." With this, holding down Push (right-click) and pressing Pull (left-click) will instead throw a coin. This makes throwing coins work more like a conventional FPS where the LMB fires bullets. This (along with all of the controls, I guess) is a WIP. There are a few scenes for the player to play around in: a tutorial and several sandboxes (as well as the Sandbox, which has some fun zero-gravity targets). cracks knuckles cries in GTX 965M Turns On Motion Blur it's gamer time (recorded back when I only had my laptop at school) There is an assortment of other videos here. The Future We've talked a lot about Newton's third law a lot, but let's take a look at Sanderson's third law: "Expand on what you have already, before you add something new." Better ways of throwing coins Changing between semi-automatic and fully-automatic coin-throwing Throwing multiple coins in different patterns Oftentimes in the books, you see Mistborn throwing a "spray" of coins at an enemy like a shotgun blast. Pewter From the start, my plan with pewter was for it to work like a shield in other games, where burning it will prevent you directly losing health. Once health actually becomes a thing, pewter will serve this purpose. HUD General polish is needed. It should be more clear when metal reserves are refilled, coins are picked up, on-screen text changes, etc. Sound The game's completely mute at the moment. I have little experience with sound design and production, so having a meaningful sound system is still a ways away. Controls I've been living in my own bubble, so I've grown accustomed my choice in keybinds. I am absolutely certain think that they're not the most intuitive. If you play the game, please let me know which controls make sense and which ones don't. Argent threw in the idea of using bullet time (or, perhaps, Feruchemical zinc time) for steel and iron. It would help a lot to make Pushing, Pulling, and target selection easier. In general, make target selection better. When you're surrounded by metal objects, there is a lot of visual clutter on the screen. I need to make a better system of prioritizing target selection so that you can say "I want to choose this target" and not accidentally select a target in front of or behind it. I definitely plan on adding macros/techniques for Pushing and Pulling. Vin's Horseshoe Wheel is one example. What I call the "centrifuge" is another - Pulling an object such that it orbits around your body, then releasing it such that it flies in the targeted direction. Lurchers never got their fair share of offensive combat in the books, so I want to show how formidable they can be, with a spicy little feedback loop or two. Other Allomantic metals Tin: zooming in, informative HUD elements about the environment, dispelling mists/visible stars in Luthadel. Bronze: see nearby sources of kinetic Investiture, such as puzzle elements or enemies that would try to Push on you. My requests for you: Play the game! You can download it from my GitHub. What controls make the most sense for you? What bugs and physics kinks do you find? Sanderson's 0th law says to err on the side of awesome. What should I add that would be fun? Mistborn is a fantasy novel, after all - so what are your fantasies for Allomancy in a game?
