U.S. Navy Test-Fires First Working Prototype Railgun

The Ultimate Bullet Train: Watch The Amazing Video Of The Railgun That Can Hit Targets 100 Miles Away At Seven Times The Speed Of Sound -- Daily Mail

* Futuristic weapon is another step closer to being deployed
* Navy reveals industry-built prototype is now being tested
* Uses magnetic field and electric current to generate energy

A futuristic supersonic weapon which fires ammunition up to 100 miles is another step closer to being deployed by the U.S. Navy.

Officials have revealed an industry-built prototype of the electromagnetic railgun is now being tested at its Naval Surface Warfare Centre Dahlgren Division in northern Virginia.

The weapon, which it is hoped will be fitted on ships from 2017, uses a magnetic field and electric current, instead of chemicals, to generate energy to fire the rounds.

Explaining Quantum Computing

MIT's Scott Aaronson Explains Quantum Computing -- Forbes

MIT’s Scott Aaronson, who works with the physics of quantum computing and is a friend of the blog, has a really great, down-to-earth article on quantum computing in the New York Times that I highly recommend reading as a nice primer for what’s possible and what isn’t.

Probably most interesting to me – and I follow quantum computing a lot – is one of the more overlooked aspects of quantum computing, and that’s its application to physics and chemistry research. Here’s a brief snippet.

How Heels Damage The Body

Fashion's High Price: How Heels Damage The Body -- Live Science

The laundry list of damage that high heels can do to your body just got longer: According to podiatrists, high-heeled shoes are one of the most common causes of ingrown toenails.

This toenail problem, which occurs when the toes are compressed so that the big toenail grows into the skin, is usually nothing more than a painful annoyance. But ingrown toenails can become infected, sometimes necessitating the removal of the entire nail.

Visual Comparison of Earthquake Strength

An Excellent Visual Comparison of Earthquake Strength -- The Atlantic

Think the 1994 Northridge quake was strong? How about Haiti's 2010 quake? This United States Geological Survey video by NOAA employee Nathan Becker puts the energy released by earthquakes over the last 50 years in startling perspective. While I know that the scale that we use to measure earthquakes is not linear, it is difficult to make my brain believe it until I see it laid out like this. Take a look for yourself, and give thanks that you weren't in Chile in 1960 when the strongest quake ever recorded struck.

Android Takes The Fight To iPhone With Trio Of Next Generation Quad-Core Smartphones That Are TWICE As Fast - -Daily Mail

Android smartphones have taken the fight to Apple after launching the first quad-core handsets that work faster than iPhones.

HTC, LG and Huawei all showcased the new technology – which will be released later this year – at the Mobile World Congress fair in Barcelona.

The phones, which all use Android 4.0 operating systems, should work twice as fast as the iPhone 4S, which uses a dual-core A5 processor.

Snowfall In Baghdad 1,000 Years Ago, And Again In 2008

Ice one: Snow fell on Baghdad in 2008 for the first time in memory

The Ancient Arabic Writings That Reveal Desert City Of Baghdad Was FROZEN Over 1,000 Years Ago In New Clue Over Climate Change -- Daily Mail

* It snowed three times between 908 and 1007 - but not again until 2008

Temperatures in Baghdad range from around 2C in winter to 45C in the summer – but ancient Arabic writings have revealed that the city experienced a dramatic frozen period around 1,000 years ago.

Spanish researchers from the University of Extremadura found 9th and 10th century (3rd and 4th in the Islamic calendar) sources that refer to snowfalls in the Iraqi capital in 908, 944 and 1007 and even rivers being frozen.

These are extreme events for Baghdad - for example, the only snowfall in the modern era took place in 2008 - and help meteorologists better understand today's climate.

Trillion-Frame-Per-Second Video -- Physorg.com

By using optical equipment in a totally unexpected way, MIT researchers have created an imaging system that makes light look slow.

MIT researchers have created a new imaging system that can acquire visual data at a rate of one trillion exposures per second. That’s fast enough to produce a slow-motion video of a burst of light traveling the length of a one-liter bottle, bouncing off the cap and reflecting back to the bottle’s bottom.

Media Lab postdoc Andreas Velten, one of the system’s developers, calls it the “ultimate” in slow motion: “There’s nothing in the universe that looks fast to this camera,” he says.

Double-Blind Violin Test: Can You Pick The Strad? -- NPR

In the world of violins, the names Stradivari and Guarneri are sacred. For three centuries, violin-makers and scientists have studied the instruments made by these Italian craftsmen. So far no one has figured out what makes their sound different. But a new study now suggests maybe they aren't so different after all.

OK, here's a test. Clip one is a musical phrase from Tchaikovsky's Violin Concerto in D Major. Clip two is the same phrase. The same musician plays both. But one is on a Stradivarius violin, the other on a violin made in 1980. See if you can tell the difference.

100,000 Times More ‘Nomad Planets’ Than Stars?

Galaxy May Swarm With 100,000 Times More ‘Nomad Planets’ Than Stars -- Kurzweil

There may be 100,000 times more wandering “nomad planets” in the Milky Way than stars, and some may carry bacterial life, according to a new study by researchers at the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC).

If any of these nomad planets are big enough to have a thick atmosphere, they could have trapped enough heat for bacterial life to exist,” said Louis Strigari, leader of the team that reported the result in a paper submitted to the Monthly Notices of the Royal Astronomical Society.

100 Billion Stars In The Milky Way

An Otherworldly Discovery: Billions of Other Planets -- Wall Street Journal

Astronomers said Wednesday that each of the 100 billion stars in the Milky Way probably has at least one companion planet, on average, adding credence to the notion that planets are as common in the cosmos as grains of sand on the beach.

The finding underscores a fundamental shift in scientific understanding of planetary systems in the cosmos. Our own solar system, considered unique not so long ago, turns out to be just one among billions.

Until April 1994, there was no other known solar system, but the discoveries have slowly mounted since then: The Kepler space telescope, designed for planet-hunting, now finds them routinely.

Is Google 'Dumping' Search

Why Google Is Ditching Search -- CNET

There has been a huge maelstrom about Google integrating Google+ into its search links. And it all misses the point.

Twitter and others are complaining that Google is throwing its massive 65 percent plus market share weight around and quashing smaller competitors. The reason Twitter and others are so threatened is that the pattern of shared links within Google+ provides a decent enough indicator as to what links are interesting. What's important is what's trending, and algorithms can get a sense of that with just a subset of everything that's getting shared on the Web.

How Apps Have Taken Over The World -- The Guardian

Steve Jobs initially resisted apps, fearing sabotage. But when the late Apple chief relented in 2007, the floodgates opened

A ticker on the front of Apple's website rolls over relentlessly, increasing by about 500 a second as it moves relentlessly towards 25bn.

It is counting the number of units of application software downloaded from the company's App Store – and the rise of a business that barely existed five years ago, but which now dominates daily conversation so much that the phrase, "There's an app for that", has become both an offer of help and a joke.

The counter is expected to hit the target by early March. By then, users will have spent about £3.6bn buying apps through the store, of which Apple will have passed on £2.5bn and retained £1.1bn.
