The energy released was mind-numbing: in one-fifth of a second, this supercharged magnetic neutron star blasted out as much energy as the Sun does in 250,000 years!"

There's no way for me to get my head around these numbers to "truly" feel it. What methods can you use to visualize such extreme numbers?

A fifth of a second is about the time it takes to blink. It's about 12 frames of a 720P HD video signal.

NASA Tests Flying Airbag Screenshot-sm 118

coondoggie writes "NASA is looking to reduce the deadly impact of helicopter crashes on their pilots and passengers with what the agency calls a high-tech honeycomb airbag known as a deployable energy absorber. So in order to test out its technology NASA dropped a small helicopter from a height of 35 feet to see whether its deployable energy absorber, made up of an expandable honeycomb cushion, could handle the stress. The test crash hit the ground at about 54MPH at a 33 degree angle, what NASA called a relatively severe helicopter crash."

Zombie Pigs First, Hibernating Soldiers Next Screenshot-sm 193

ColdWetDog writes "Wired is running a story on DARPA's effort to stave off battlefield casualties by turning injured soldiers into zombies by injecting them with a cocktail of one chemical or another (details to be announced). From the article, 'Dr. Fossum predicts that each soldier will carry a syringe into combat zones or remote areas, and medic teams will be equipped with several. A single injection will minimize metabolic needs, de-animating injured troops by shutting down brain and heart function. Once treatment can be carried out, they'll be "re-animated" and — hopefully — as good as new.' If it doesn't pan out we can at least get zombie bacon and spam."

Fact: Every year, the temperature rose on average 0.01K or 0.0039 percent.

Fact: Temperature differences of less than 0.01 K require very sensitive equipment to be measured correctly.

...

Let's imagine that out of 73000 temperature readings only 3 values were only 1 degree Celsius off. The person reading the temperature scale made an error and incorrectly reported 21 degrees when the true daily average was 20 degrees.

If we have 3 erroneous readings out of 73000, the error is 50% higher than the assumed increase in global temperature.

Fact: 3 measurements out of 73000 being 1 degree off is an error of 0.00004 degrees. This is 1 day's worth of global warming.

If we thought we were able to predict when a specific global warming event would occur, and we we were actually wrong by an entire day, then obviously global warming is a crock.

Fertility Clinic Bows To Pressure, Nixes Eye- and Hair-Color Screening 847

destinyland writes "A fertility service in L.A. and New York screens embryos for breast cancer, cystic fibrosis, and 70 other diseases — and lets couples pick the sex of their babies. But when their pre-implantation diagnostic services began including the baby's eye and hair color, even the Pope objected — and the Great Designer Baby Controversy began. '[W]e cannot escape the fact that science is moving forward,' the fertility service explained — before capitulating to pressure to eliminate the eye and hair color screenings."

The neutrinos from a core collapse supernova would be lethal to humans at the distance of Jupiter. Any given neutrino has very little chance of hitting interacting with normal density matter it passes through, but there are a LOT of neutrinos: about 0.05 solar masses of them.

Furthermore, they are the first things that escape from the core (apart from gravitational waves) since they move at near-lightspeed and have very little chance of interacting with the envelope of the star. The big flashy special effects are driven by the shockwave from the core reaching the surface, and that takes hours. So if you were at the distance of Jupiter, you would have time to die from neutrino effects before the blast hit you.

Admittedly, Betelgeuse is somewhat further away than Jupiter, and the only neutrino effects are likely to be a lot of very excited astrophysicists. But both Jupiter and Betelgeuse are much closer than 99.9999999999999999999% of the Universe, and much further away than everyone you've ever met, so the distance scales aren't that different.

Comment Re:Punched cards - there was a machine for that (Score 2, Interesting) 731

Around 1980, there was a program called SPIKE, which was a virtual keypunch. It put an image of a punch card up on the screen (character graphics on a Z-100). As you typed, it wrote the characters (uppercase) at the top of the card, and blacked out the appropriate squares.

It had a mode to do blind typing (not all keypunches printed the characters at the top of the card--that cost extra). It also had a 'dropdeck' command to shuffle the lines of your file.
