When a magnet will attract iron for , well who knows. Why do physics still teach that energy can't be created when It seems obvious it is.

Seriously, this day is dragging on for no reason. Does anybody know how to make the clocks go faster? Sadly, I'm at work, so "having fun" is simply not an option...

On a relitively cool summer morning in Phoenix AZ ( a rare and precious thing) it was noticed that traffic noise was particularly loud....It was hypothesized that the reason that the noise was louder was because the cool morning made tires noisier. Is that person even a little correct? ( lower temps mean that tires have denser air making them "flattter" What do you say?

Where would you go? Imagine that there was a big flying pod into whic you could get in. It would protect you, give you fresh air, and food. You could fly around on a planet in it. The temperature inside is always monitored. So where would you go?

In a certain village, there are 50 couples. As it turns out, everyone in the village is having an affair. This despite a particularly gruesome custom which requires a wife, upon discovering that her husband is having an affair, to kill him the following morning. Even more oddly, the women in the town talk quite freely about their activities! In fact they are all perfectly aware that any woman who is having an affair will tell EVERY other woman in the village except, of course, for the wife of the man with whom they are having the affair. Yet life there goes on quite peacefully since no woman can know for sure that her husband is actually having an affair. One day, a well revered wise man visits the village and announces that someone is having an affair. What happens after this?

For statistical purposes please include name of community/city you live in (i.e. North Park, Chula Vista, Del Mar, University City/UTC, La Jolla, etc. I'm trying to determine if this is popular with San Diegans and will share my results with those who e-mail me to request the final tally. IF you're really daring, give me your street name (but NOT your actual address - that can be dangerous as you don't know me & I don't know you) - I will do a plot of those who give me a street name and will share it once it's done.
