### Yesterday

I had a good day yesterday, as far as both productivity and personal happiness go. I read all of The Brief And Frightening Reign Of Phil, which

I told her I knew the primitive roots of all the prime numbers less than 100. That was not what she was asking, but I could not resist showing off. After flexing my math muscles for her, I explained to her what primitive roots are.

For those unfamiliar, r is a primitive root of a prime number p if the smallest number k such that r

I just reread that last sentence and realize there are two things I need to put on my to-do list:

I felt so manly.

**lexvonrockets**had loaned to me and got two of the three tests I'd given this week graded. That night Elle called me with a math question. She was reading a paper about an algorithm that used primitive roots. She was not familiar with primitive roots, and asked me what I knew about them.I told her I knew the primitive roots of all the prime numbers less than 100.

^{k}mod p=1 is p.I just reread that last sentence and realize there are two things I need to put on my to-do list:

- learn how to write predicate calculus in HTML
- quit showing off about stuff nobody cares about

I felt so manly.
