Re: Registration 2017
Victoria Park simply got moved to the top of the district event listing. Sometimes the order of events on FIRST's page is a little scrambled, and my page only reflects that.

Re: Optimization, when to stop
Sometimes we have to forgive the theoretically minded for exploring the realm of possibilities.

Re: Hex Turning - Runout Question
Shouldn't this be just as good as the runout from turning anything else while held in a 3 jaw chuck? If the chuck is not holding the part concentric, the turned diameter won't be concentric,...

Re: Math Quiz 9
It's hard to disagree with your first figure.
If you can switch the order of integration and then integrate the pdf over theta, then you should have a pdf for L only. I'm trying to wrap my head...

Re: Math Quiz 9
FTFY. When discussing cardinality, distinction between aleph-0 and aleph-1 is key. The integers (aleph-0) have measure 0 in the real line (aleph-1), so any "proportion" there would be 0.
