*I need to get a better grasp on what a universal machine is, yes. I am
interested in finding out how Tegmark's argument for mathematicalism is
invalid, especially since I'm using it to motivate my research.*

*I'll have to think more on Jannes' paper. As I basically resting the
motivation of my research on the correctness of "ERH implies MUH," I'm
trying to formulate a good refutation to his paper.*
