Divide by Zero
You can't divide by zero. Computers and mathematicians choke up, and you'll never get an answer. That's assuming, of course, Dr. James Anderson, of the University of Reading, is not batty. The professor has come up with a new mathematical concept, which he calls 'nullity,' that allows you to divide by zero. I don't really understand the math, possibly because the explanation is so brief, but I think it's cool, even if it is just an example of something that pisses me off: making up a new 'imaginary' number to solve a real problem you can't just solve.
It's a big day for the previously-believed-impossible: analysis of satellite imagery suggests that there may be periodic flash floods on Mars. Liquid water on Mars would change how we think about the planet, and what life might be like there. Also, the Conservative Jewish movement has decided to allow gay marriage and ordination of gays. But it still bans anal sex. This is a major step in a good direction; I hope that it will be followed soon with full 'decriminalization' - these rabbis (even, or perhaps especially, those who resigned in protest) know that there are bigger gefilte fish to fry.
Similarly improbable, researchers claim that MRI scans of the temporal gyrus reveal pre-schizophrenia. If this turns out to be real, it is a massively huge finding - even if nothing can be done really to prevent the disease today, knowing that such 'priming' conditions exist would give researchers all kinds of direction in searching. Very cool!
