Re: Nondeterministic Universe, posible?

Re: The natural structure of mathematics

I certainly did not start with foundational set theory... However, my first analysis class did start with taking about a dozen given properties of numbers and building the calculus from that. My first algebra class was similar, taking the eight field axioms and deriving properties of fields and line...

Re: Misconceptions within Physics and Astronomy

People misinterpret various theories all the time. The average layman would probably attribute everything in modern cosmology to Einstein and MAYBE Hawking. Plus, people often fixate on certain results of a theory, thinking that that's the theory itself (E = mc^2). I once got the crazy idea of findi...
