I'm wondering if I'm alone, but is anyone having a hard time trying to understand how technologically advanced Roshar is, or if it's simply being inconsistent?
At first glance, I thought it was like a classic fantasy setting historically, but then we're in RoW, we discovered a bunch of things. We are told the relationship between math and music, specifically wavelength and frequency. Both of which are much more modern discovered, and the relationship between frequency and music which is even more modern. And the first theories about frequency were about electromagnetic fields and light, not sound. We learn that Navani has a vacuum tube, courtesy or a Barometric Institute, but why would they have invented that? A vacuum tube is much different than a barometer. Like, a barometer uses a Torricellian vacuum, it is not the same principles of a vacuum chamber, so I have to wonder why a barometric institute would have this device. The process to extra air from the vacuum tube makes it pretty clear that it's not the same kind of vacuum used when taking barometric readings. Then Navani talks about waves not traveling through a vacuum, but how do they know that? Because again, that's a fairly modern theory. How does she know what a vacuum less environment is, let alone that sound waves can't travel through it? And a major statement that Navani keeps making is that oil and water can mix, but theory behind emulsification is again, another fairly modern idea.
I think there's more, but I'm just extremely confused, because Roshar does not know the existence of bacteria. Because if we remember, Kaladin didn't understand why he had to wash his hands before surgery, other than that was the wisdom of the Heralds. So how are complex theories about frequency, wavelength, even emulsification known as such common ideas to Navani? Because we know Raboniel does not know emulsification, and much of the wisdom of the Heralds was lost in time.
I'm just wondering if anyone else has an opinion to help try to bridge this gap. I mean, the more I look, the more I see that it's not exactly medieval fantasy, but maybe pre-industrial, but even then, a lot of these ideas weren't even thought of, and yet it's common knowledge to Navani. Just hoping someone can make a more rational argument, because I felt like all the science being thrown at us through the experiments felt completely out of place based on my perceived technological level of their society.
