Unfortunately, lasers have become so cheap, and super powerful laser-pointers (which has no real world use whatsoever)

I have my physical chemistry students build a Raman spectrometer using a 300 mW green laser pointer. So they absolutely do have a real-world use. The cheapness and power is what makes it a worthwhile and feasible experiment to do.

Most resources are recyclable, but simply end up in trash heaps because (for now) the energy and sorting costs of recycling makes it inefficient.

Personally, I like the idea of 21st century miners working in old landfills to get metals instead of chopping off mountaintops.

Exactly.. Every time I throw a "recyclable" tidbit into the regular trash I like to think of some descendant in the far future having his day made when he unearths my piece of valuable trash.

That was certainly the experience I witnessed in both undergraduate and graduate school.

Again I'm calling BS on this, at least in science. Where I work, almost the entire graduate department seems to be Chinese. But these are smart guys, and gals. They have a lot to learn, but they earned their way here.

It is a mixed bag, honestly. And seems a lot of the best and brightest stay here while the dregs return home.

This makes me want to throw-up.

Having "the people" review NSF grants, the same people of whom half believe that antibiotics kill viruses (imperiling all of us when they strong arm their spineless doctors into prescribing antibiotics for colds) and think that humans and dinosaurs lived at the same time, is a freaking ridiculous idea. Furthermore, the idea that targeting grants individually in NSF, whose budget, at $7 billion is 0.2% of the total budget is an effective way of cutting the deficit is asinine. And to top it all off, that measly $7 billion is one of the major reasons the United States is still a power in science and technology at all, especially as private R&D collapses in the face of the recession (in the short term) and Wall Street's fetish for quarterly results.

Fuck you, Eric Cantor. Fuck you, ignorant Republican douche-bags. I am D-O-N-E done. We are going to Hell in a handbasket, and instead of rearranging the deck chairs on the Titanic (which would be bad enough), you are stealing life jackets from children and setting them ablaze because the water is cold and we need to keep warm.


The Placebo Effect Not Just On Drugs 824

dvdme writes "It seems the placebo effect isn't just valid on drugs. It's also a fact on elevators, offices and traffic lights. An article by Greg Ross says: 'In most elevators installed since the early 1990s, the 'close door' button has no effect. Otis Elevator engineers confirmed the fact to the Wall Street Journal in 2003. Similarly, many office thermostats are dummies, designed to give workers the illusion of control. "You just get tired of dealing with them and you screw in a cheap thermostat," said Illinois HVAC specialist Richard Dawson. "Guess what? They quit calling you." In 2004 the New York Times reported that more than 2,500 of the 3,250 "walk" buttons in New York intersections do nothing. "The city deactivated most of the pedestrian buttons long ago with the emergence of computer-controlled traffic signals, even as an unwitting public continued to push on."'"

If you are going to link to a graph, you might actually want to look at it in detail first. Notice how almost every year it starts low in January, jumps up in the summer, and then in January it drops back to roughly the same spot it was the previous January? Notice how in 2009 that didn't happen? The summer gain was very, very small, and then the winter drop is way lower than the previous january? Now for 2010 we see that the summer gain was much bigger, pretty much on par what it has been almost every other year (other than 2001 and 2009). So that's a positive indication right there that at least things have stabilized. Yes, employment is dropping, but that's the normal cyclical adjustment. We won't be able to tell for a few more months (probably closer to 6 month) whether things overall are better, worse, or about the same.

Huh? According to the graph, employment was 64% in January 1999. In January 2010 it was 58%. There is a cycle in there, yes, but the over alltrend is down.

Its a pretty ordinary name in german speaking countries. It basically means "The lucky tree gardener". Daredevil indeed.

Yes, but in English speaking countries it comes across as "The man who trims arse hair".

That is one of the funniest exchanges I have ever read.

"One Architecture, One OS" also translates as "One Egg, One Basket".
