I am writing an expository book for myself(It is just some notes which I want to convert into electronic format). I have divided it into chapters.
I have this idea in my mind.
Instead of writing
Chapter $0$
I think it will look more beautiful("mathematically beautiful") and aesthetically pleasing if I write
Chapter $e^{i\pi}+1$
Any suggestions for other numbers. I have around $12$ chapters excluding Chapter $0$.
P.S. Kindly correct the tags, if they are not OK.
Here are some sites that are effectively museums of numbers, which should offer plenty of inspiration:
What's Special About This Number?
Number Gossip
The Secret Lives of Numbers
Notable Properties of Specific Numbers
Zoo of Numbers
The Database of Number Correlations: Properties and Meanings
