Favorite (mathematical) theorems:
- Pythagoras' theorem.
- There exist irrational numbers.
- Euler's theorem: exp(i*pi)=-1.
- The fundamental theorem of algebra: every polynomial equation has a complex root.
- Lagrange's theorem: the order of any subgroup is a divisor of the order of the group.
- The fundamental theorem of ultraproducts (too complicated to explain, but a great theorem).
- Fermat's last theorem (as proved by Andrew Wiles et al.)
- Cantor's theorem: the irrational numbers are uncountable.
- The prime number theorem.
- The classification of finite simple groups.
- Lagrange's theorem: every integer is the sum of no more than four squares.
- Cayley-Hamilton theorem: every square matrix satisfies its characteristic equation.
- The Brouwer fixed point theorem: any continuous mapping of a unit disk onto itself will leave at least one point unchanged.
- Gödel's incompleteness theorem: in any system powerful enough to include arithmetic, there are true theorems which cannot be proved within the system.
- Turing's theorem: the halting problem is undecidable.
I know that once I post this I'll think of plenty of others...
