Random rants, part one

I wonder if football players and coaches care that their every move at a game is being televised, right down to the seemingly private moments on the sidelines when their mug shot fills the screen. What's up with that also? I don't want to see random photos of some guy's face on my screen! I want to see the flipping GAME. Well, not always. In fact I don't always watch foot ball. But still. They do it with baseball too, which ticks me off to infinity, since baseball is a game I do watch.

The number infinity irks me. There are only two mathematical functions which can equal infinity at all ever, and they're two that a lot of people might not recognize: summation (∑) and limits (abbr. lim). Those are both calculus functions by the way. I've noticed that not a lot of people I meet understand too much about calculus. What is this world coming to?!

Another irksome number is infinity's evil twin, epsilon (ε) or 1/infinity. It's a strange number, because if ) 0.9999999... equals one (proof at the end of this post) than 0.00000...1 must be zero, right? Apparently not. Because 5-ε<5, or so they say.

Proof:

Step one: 1/3=0.33333...
Step two: 2/3=0.666666...
Step three: 3/3=0.9999999...
Step four: 3/3=1
Step five: use "if a=b and b=c then a=c" proof format: if 1=3/3 and 3/3=0.999999..., then 1 must equal 0.9999999...

Q.E.D. :)
