What do you like about this subject?

What is there not to like? I like the numbers and the equations. And the puzzles they allow you to solve.

What do you still hope to achieve/learn in this field?

Though I am good at math, there is still huge amounts I don't know. I'd love to learn it all. But mostly, I just want to learn to how to make everyone love math like I do. (Sorry to be so gushy but it is true.)

Something interesting about this subject that others may not know:

While physics and chemistry have marvelous theories for how the world works, none of it can be proven definitely to be true. But math is truth, by definition.

Something controversial or provocative about this subject

If you type 55378008 in a calculator, turn it upside down and read the display, it might make you laugh.
