Better Explained

Oy.  Things I have been missing all my life, and I’m not sure how I missed them.  Maths for people who like maths, but who think technical Wikipedia is mostly useful for illustrating the distinction between explanations and Ramsey sentences.

Bonus: intuitive understanding of Euler’s formula.  For free. Seriously.
