Like.
You don’t even have to think the universe actually is discrete. All you have to do is show that your discrete math matches observation. -

Matterwave replied to the thread How do atoms build thoughts and emotions?.I would say so, for Descartes' dualism is not the only alternative. Which concrete predictions were these?
-
Matterwave replied to the thread How do atoms build thoughts and emotions?.Yes. A position around what there is, not necessarily around what can be known. It is just my understanding of it. :)

Matterwave replied to the thread Undergrad Problem in understanding composition of covariant derivatives.Could you explain your notation? Are you using abstract index notation? That is the notation I know that looks like what you used. In...
