I'm definitly not complaining but I've been having to run the A/C and it's January and I just thought it was a little odd. I figured it was just going to take a while for it to get really cold then winter would end up being later in the year but at this point I guess it's just a really mild winter season. Anyone know any reasons why it's like this this year?

I read the book PREY By Michael Chriton and it spoke about small naomachines that took on a form of their own. being able to think on their own.

Well...thats one time ive heard nanomachines mentioned. however....

mainly...i heard of nanomachines in a video game. metal gear solid. where the main characters, working for secret government services. anyways....calls would be taking in frequencies using these nanomachines. is this possible? if so, how?

in the game the characters had these nanomachines in their ears, i pressume. small enough no one could notice yet able enough to be able to receive and make frequency calls.

warmings of the past. For instance the end of the ice age? There were no cars, no factories, etc...Did the men of old burn too many bonfires? And what about the unusually cold temps in California which is threatening the citrus crops? Is this evidence of global warming?

I'm all for cleaning up pollution, but isn't global warming being blamed on mankind just hype?

I want to write two "3-digit" numbers as one "3-digit number" and be able to sort both original 3-digit numbers out later too.

For example: 222+152=374. Now, once I get 374, is there ANY way to determine that 374 came up by adding the values 222 and 152?

Its not a problem if the final number (374 here) increases to anything betweeb 0 and 999, but it should be a 3-digit number as well.

Any help greatly appreciated. Thanks.
