...Today, there are practically no more cars with turbos (except for a few exceptions). I paid to fix the problems, not Nissan.

Are you kidding me? Let me try to list a few of the many cars that now come with turbos: Mitsubishi Lancer Evolution, Subaru WRX, Dodge Caliber SRT4, Chevrolet Cobalt SS, Mini Cooper S, BMW 135i (and all other -35i cars), Mercedes Kompressor models, Hyundai Genesis Coupe, Nissan GT-R, Ford Taurus SHO, Mazdaspeed 3, Volkswagen/Audi GTI and TDI models, Bugatti Veyron, and pretty much any diesel vehicle out there.

Turbochargers have become very popular since they allow a smaller engine to achieve higher power ratings under heavy load but still get good fuel economy under lighter loads.

Comment Re:Homeopathy != All Non-Pharmaceutical Medication (Score 1) 507

To be fair, there is little evidence for vitamins and minerals either (or, more specifically, no evidence that supplements would help anyone with a moderately balanced diet). Specific deficiencies are known to increase the risk of certain problems, but there is little evidence that you actually need 100% of the USDA allowance for most, or that taking more than the USDA allowance decreases the risk even further. The largest controlled study I'm aware of (News report) found no benefits in any of the 10 categories studied, including "the rate of breast or colon cancer, heart attack, stroke, blood clots or mortality." Studies show benefits from fruit and vegetable intake (which contain vitamins and minerals), but not from supplements.

Comment Re:Heomeopathy = Placebo (Score 1) 507

FYI, every large scale, properly blinded study of acupuncture done so far has found it to be as effective as sham acupuncture - and depending on how you define some of those other modalities you mentioned (light and air therapy are basically bullshit, but going outside isn't), they may also be just as effective as placebo.

I'm glad homeopathy is getting a beatdown in the UK, but it's really just the most obvious bullshit in health care.

NHS Should Stop Funding Homeopathy, Says Parliamentary Committee 507

An anonymous reader writes "Homeopathic remedies work no better than placebos, and so should no longer be paid for by the UK National Health Service, a committee of British members of parliament has concluded. In preparing its report, the committee, which scrutinizes the evidence behind government policies, took evidence from scientists and homeopaths, and reviewed numerous reports and scientific investigations into homeopathy. It found no evidence that such treatments work beyond providing a placebo effect." Updated 201025 19:40 GMT by timothy: This recommendation has some people up in arms.

I'm not saying advancing more gifted students is a bad thing, but what's the rush? Will it really matter in 20 years if they graduated at 16 or 18 years old?

It might, in the face of NCLB, those last two years could kill any motivation they might have. Going to college 2 years early is not just an advancement, it's recognition of excellence, the same sort of recognition that's quashed in high school because of "A winnar is everyone!"

Comment How they are doing it? (Score 4, Interesting) 224

Unfortunately, the linked to post and video doesn't give much details. Naively, I expect that the computer program is first figuring out very quickly what the series of movements to solve the cube and then implementing those. There are around 4 * 10^19 possible configurations for a Rubik's cube, but the group theory allows one to work out what steps to take without having to do very exhaustive searches since the Rubik's group is very well-behaved. However, this assumes one is in an actually solvable configuration. I'd be curious to find out if they've debugged the device well enough to make sure it doesn't hang or get in some infinite loop if one gives it an unsolvable cube (not all possible permutations of squares are solvable. Most trivially, edges need to stay on edges, corners on corners and centers on centers. But some configurations are still not solvable. For example, if one swaps two center stickers it isn't hard to see that that lays outside the Rubik's group of reachable permutations).

Do you know that MRI scanners use SQUIDs?

Seriously: http://en.wikipedia.org/wiki/SQUID

Not really. If you read the wiki article carefully, you will see that SQUIDS are used in "microtesla" MRI. This is not the normal MRI. If you go to a hospital you will probably get a 1.5 Tesla scan. If you volunteer as a research subject you might get a 3 T scan or rarely a 7 T scan.

SQUIDS are used for MEG though. If you are being prepped for brain surgery for epilepsy you might get one of those, although most places still just use EEG, which is an order of magnitude (or 2) cheaper.

Comment Electric Zamboni (Score 3, Interesting) 356

Zamboni has had electrics for a long time.

I've been watching US College hockey for a long time. Most rinks have a Zamboni. They last a long time. I've seen a few new ones and usually the go electric because the propane ones generate CO2 and that's not good indoors. I've seen rinks add a 2nd Zamboni for faster resurfacing between periods too.

Zamboni isn't the only maker of ice resurfacers. I bet most rinks in the US are Zamboni though. I remember Union College in Schenectedy had another brand.

FWIW Clarkson University gave Mr Zamboni and honorary degree in 1988 in recognition of his engineering achivement in creating the ice resurfacer.

I have found that asking them how antibiotic resistant strains of bacteria have come about so quickly usually shuts them up.

I must deal with more up to date creationists than you. They believe in natural selection, but evolution requires speciation events, which they don't believe in. Good thing that several of those have been documented (one was just published last week or so...).

Lies was a great book, BTW.

I always wondered, would a laser be defeated if you gave the missile a mirror paint coat?

If you can create a perfect mirror, which can also stand temperatures of reentry into atmosphere without losing reflective quality, then yes. But we live in a real world and mirrors are not perfect and are not that tough. They don't deflect 100% of light. High power laser beam will melt mirror. Mirror might reflect laser for some really short period of time. Once mirror starts melting, it will stop deflecting laser.
