So, there's a line in Elantris that has always fascinated me. Raoden is reading really old books, and he says that some of these books mention words such as "frequency" and "pulse length." I'm a physics major, this reminds me a lot of quantum physics.
Brandon Sanderson
Yes, it does!
Questioner
So, my question is, how much is quantum physics a part of the magic in the cosmere?
Brandon Sanderson
Here's the thing. I don't know quantum physics well enough. That's a rabbit hole; I am an armchair scientist, I do not have a degree in physics. And so, while I really like it, I build it in... When I'm doing this, what I usually do is I build in cosmere versions, so I can't be held accountable to getting some little thing wrong. So, yes, quantum physics is important. But, in some ways, some of the things in the cosmere are more like the pop science version of quantum physics, what everyone thinks quantum physics is but really isn't, are actually some of the things in the cosmere. The fun, awesome version of quantum physics. I try to make some of it as accurate as I can, not having a physics degree. But I have to be aware that... I am not writing science fiction, I'm writing fantasy, so there will be things that you're like, "That's not quite right," but it works in the cosmere.
Questioner
Anywhere I should keep my eye out for more stuff like that.

In Words of Radiance... when was the interlude, is it in the first book? The spren, they took their measurements. That's part of it. We're gonna have, just, little things like that around that are relevant, but I'm not gonna dig into it deeply until [Mistborn] Era 4, probably.
