The Sun is saying that the sick bastards of Al Qaeda had stuffed 2 dogs with bombs, explosives and detonators back in 2008. The dogs were meant to board a flight from Baghdad to Los Angeles and explode in the air. More »
We have hundreds of 3-phase, 400/440 volts, 50 C/s, 1450 rpm, 0.8 Pf electric motors of SIEMENS origin coupled with 750 to 2500 IGPM Water pumps. All are controlled through Star/delta Starters. Recently, due to increased electricity tariff and other issues, we are considering to replace the star/
Edward Horsford has taken a series of high-speed pictures that captures a water balloon...without the balloon. The shots are snapped at the point of explosion, when the balloon skin breaks open. It looks like he's somehow holding a ball of water. More »
The idea of a single general-purpose "computation" device is fading into the same historical background as having a single steam engine to power a whole factory, or a single electric motor to power every appliance in a house. As it fades, designers and developers have to learn to design smart things that serve the interests, abilities, and needs of people. We must create a practice of ubiquitous computing user experience design.
Asteroids headed for Earth are scary. So get to know them a little! You can use the Impact: Earth! calculator to see what kind of damage an asteroid will cause. It's totally not as scary when you crunch the numbers. More »
The guest this week on Point of Inquiry is blogger, podcaster, and philosopher-skeptic Massimo Pigliucci of “rationally speaking” and CUNY. Here’s the show description:
It’s a longstanding debate in the philosophy of science: Is “demarcation” possible? Can we really draw firm lines between science and pseudoscience?
Massimo Pigliucci thinks so. In his new book Nonsense on Stilts: How to Tell Science from Bunk, Pigliucci attempts to rescue the notion that there are claims we can rule out, and claims we can rule in—a real means of determining what’s science and what isn’t.
Along the way, Pigliucci touches on howlers like creationism and astrology, and borderland areas of research like SETI—and weighs whether science can ever hope to test claims about the supernatural.
Massimo Pigliucci is chair of the philosophy department at CUNY-Lehman College. He was formerly a professor of ecology and evolution at Stony Brook. He’s a prolific blogger and commentator on issues concerning science and skepticism and a prominent battler of creationists and other nonsense peddlers.
Once again, you can listen to the show here, and you can order Pigliucci’s book Nonsense on Stilts here.

Scientists have found dead and dying coral reefs 4,500 feet deep in the Gulf of Mexico. The dead coral means that oil from the BP oil spill is harming marine life in the deep ocean too. More »

The Great Florida Beachwalk is a campaign to make people aware that Florida’s beaches are NOT covered in oil. They are clean and healthy. The idea was to assign each mile of Florida’s 825 miles of sandy beaches to a volunteer, who would show up Saturday morning, walk the mile of beach, take a photo [...]

Does anyone have a general diagram or schematic drawing of a typical barber chair mechanism? This would be very helpful in understanding some of the Q & A's s well as being able to confidently fish around an learn for myself.
Thanks
I have a 600VA invertor which is found to be consuming a lot of electricity at my home. It is connected to a 150Ah tubular battery. But the electricity meter keeps reading always when the supply is provided to the invertor even if no charging indication is seen there. Why is this so? How can I fi
Gaming on the iPhone is great! That is, until you try to hadouken. Then you realize its limitations. So if you're sick of using those stupid touchscreen controls, here's a desperately bright idea: attach plastic stickers to moonlight as physical buttons. More »
There are spark and chemical tests to identify different metals, but what about plastics?

Happy Saturday to all. I hope the weather has been nice where you live; I’m having a lovely Indian Summer… the best part of the South/Central United States weather patterns. Cold nights, mild days, lots of sunshine, and an overall freshness to the air.
Wouldn’t it be great if we could have weather like that more often?
Okay, enough out of me. Are you ready to tackle the riddle? I think this one is pretty straightforward, and you should nail it right off. You will be looking for a thing.
Public image found on PhotoBucket
This thing exists in the real world.
It exists as a single object.
It’s not known for sure if our ancient ancestors knew about this thing. Maybe… but more than likely not.
There is a subtle, but recognizable beauty associated with this object.
That’s interesting, because usually this “type” of object is rather flashy.
This object is something of the definition of its type.
You need to pay special attention to the images.
especially pay attention to this image
How’s that? You know where to find me!

This isn't really surprising when you think about it, but the fact that the data is in is exciting: Personal genomics tests prompt lifestyle changes. From New Scientist:
David Kaufman of the Genetics and Public Policy Center in Washington DC quizzed 1048 customers who had ordered genome scans from Decode Genetics of Reykjavik, Iceland, 23andMe of Mountain View, California, or Navigenics, based in Foster City, California.
Asked about changes in their behaviour between two and six months after receiving the results, 34 per cent of respondents said they were being more careful about their diet, 14 per cent said they were doing more exercise, and 16 per cent had changed their medications or dietary supplements.
"I was surprised at the number of people who said they'd made changes already," says Kaufman, who revealed the results this week at the annual meeting of the American Society of Human Genetics (ASHG) in Washington DC.
That's impressive because getting people to adopt more healthy lifestyles is notoriously difficult – even when family history shows a high risk of conditions like type 2 diabetes and heart attacks.
There's obviously a selectional effect at play here. People who have gone about personalized genomics are already primed to act on that data, otherwise they wouldn't have gone about it in the first place. A bigger question would be: How would a random sampling of individuals respond to the acquisition of personal genomic data and a listing of their potential risks?
My guess is that the figure would be a bit lower than that of the early adopters used in the study. Denial can be a pretty powerful de-motivational factor; people in the pre-contemplative phase of behavior change overtly ignore or dismiss information, even when it's overwhelmingly evident that their lifestyle choices have to change.
That said, these results are very encouraging; it points to a future in which behavior modification can be facilitated through the dissemination of highly personalized genetic information.
