Submission + - CalTech astronomers predict that 1 in 10,000 stars is composed entirely of metal

porkchop_d_clown writes: A recently discovered aerodynamic phenomena of turbulence, called 'preferential concentration' causes heavier materials to be sorted out of more turbulent areas, increasing their concentration in eddies.

Now astronomers are theorizing that this effect could lead to the formation of stars with no hydrogen or helium in them.

Submission + - Blood of world's oldest woman hints at limits of life ( 1

porkchop_d_clown writes: When Hendrikje van Andel-Schipper died in 2005, she was the oldest woman in the world. Today New Scientist is reporting that, at the end of her life, most of her white blood cells had been produced by just two stem cells — implying the rest of her blood stem cells had already died, and hinting at a possible limit to the human life span.

I made the mistake of buying a Ti-89 in the 90s... I liked its higher resolution screen but because it had a symbolic algebra solver it was not allowed on the SATs so I had to do the SATs without a calculator.

Later, when I took the GREs and they didn't allow a calculator of any sort I felt vindicated :P

The SATs are a total joke. They have been trying to make them more GRE-like, but I don't think they'll ever be able to get to the point where they expect High School students to do simple arithmetic without a calculator. That is a skill I picked up in college, as funny as that sounds. It's something you're supposed to learn in elementary school, but because of the prevalence of calculators it doesn't take long before students (myself included) simply forget from lack of actual practice.

As for not being different from a modern Ti calculator, I beg to differ on that one. Have you seen the Ti NSpire? They're color now and finally TI solved the issue of symbolic algebra by selling two versions - one with the feature and one without.

How do you color the whole issue as him only resigning, when three board members quit over his presence there. That's a lot of pressure from the company.

It looks an awful lot like coercion...

But, isn't it up for him to sue if he feels he did not resign voluntarily? It seems like he probably would not do so.

The problem is, the CEO's job is to be the figurehead for the company. He's not the President -- he's not in an operational position, his sole job is to represent the company to the board and the public. His inability to do so effectively is absolutely grounds for removing him. Its a fine line to walk when you get arcane labor laws into the picture, but the fact is, with the uproar he wasn't capable of doing the singular thing his job exists to do. If he was the President of the company, I doubt he would've been pressured to resign. (Its very much like the laws against things like weight or sex discrimination -- when someone's job is specifically related to their fitness or gender, its been shown repeatedly that laws like these don't apply.)
