Completely fascinated with VSauce videos on the theory of relativity (and why there is actually no gravity, and weight vs mass), Banach-Tarski Paradox (and other paradoxes, including those by Zeno) and counting pas infinity lately. The big questions, where math kisses Philosophy and Physics.

Last night, Simon was lecturing Dad about the Alpha Null (the number of cardinal numbers), various infinities and cardinal vs ordinal.
