...Prove Their Worth...

"Problems worthy of attack
prove their worth

A kind of running diary and rambling pieces on my struggles with assorted books, classes, and other things, as they happen. You must be pretty bored to be reading this...

For some reason, I'm having trouble following Needham's description of the 'quick way' (as opposed to the painful, confusing, yet naive and simple way) of figuring out winding numbers. FWIW, a 'winding number' is an integer describing how many times a (directed) squiggle loops around some point. One can just, well, count, to find the winding number, but for complicated curves, this can be difficult and frustrating. And Needham shows a way of doing it 'just like that'. And I'm having trouble seeing why it works. Harrumph. What else is new?



In other news, the South Park episode entitled 'Proper Condom Use' is a masterpiece of comedy. Just to give you a hint of the delightful flavor of this engrossing tale, the episode both begins and ends with one of the South Park kids (Cartman, if memory serves), digitally* stimulating a neighbourhood canine. A delightful and gut-busting episode. It should also be noted that it would be perfect for a middle-school level health and human sexuality course.



* - By digitally, I mean to refer to the root word 'digit', meaning finger, rather than 'digit', meaning a number.
