Restoration of Third Law of Thermodynamics in Spin Ice Films Unexpected, Researchers Say

Scientists say that contrary to popular belief, the third law of thermodynamics can be restored in thin film of spin ice. Spin ice were seen as an exception to the Third Law of Thermodynamics, which states that “the entropy of a perfect crystal is zero when the temperature of the crystal is equal to absolute zero (0 K or minus 273 degrees centigrade.” The study on spin ice (a type of crystal with ions placed in a tetrahedral shape) was conducted by researchers at the London Centre for Nanotechnology (LCN) in collaboration with scientists from Oxford and Cambridge. “Restoration of the … Continue reading Restoration of Third Law of Thermodynamics in Spin Ice Films Unexpected, Researchers Say

Missing Malaysia Airlines Flight May Be Visible On Chinese Satellite Images

A Chinese government agency reportedly released satellite images that could possibly show parts of the missing Malaysia Airlines plane, CNN reported on Wednesday. Satellite Images aired on CNN could show missing Malaysia Airlines plane.  According to the network, the images were distributed by China’s State Administration for Science, Technology and Industry for National Defense and were captured on March 9, one day after the plane went missing. The three images appear to show white objects floating in the water. Coordinates released with the images place the objects in the sea between Malaysia and Vietnam, the BBC notes. The Guardian notes that the site appearing on the … Continue reading Missing Malaysia Airlines Flight May Be Visible On Chinese Satellite Images

Mapping out Earth’s place in the universe among ‘Council of Giants’

We live in a galaxy known as the Milky Way – a vast conglomeration of 300 billion stars, planets whizzing around them, and clouds of gas and dust floating in between. Though it has long been known that the Milky Way and its orbiting companion Andromeda are the dominant members of a small group of galaxies, the Local Group, which is about 3 million light years across, much less was known about our immediate neighbourhood in the universe. Now, a new paper by York University Physics & Astronomy Professor Marshall McCall, published today in the Monthly Notices of the Royal … Continue reading Mapping out Earth’s place in the universe among ‘Council of Giants’

How NASA Sold Us The Moon

When President John F. Kennedy first roused the nation with his 1962 challenge to send astronauts to the Moon and back, most Americans took it on faith that it was a worthwhile quest. But they likely didn’t fully appreciate that in the decade that followed, NASA would also marshal all its marketing and public relations know-how to ensure that the court of public opinion would continue to give the space agency’s lunar efforts a hearty thumbs-up. You note that Apollo was the most important marketing and PR case study in history. How so? Scott: Imagine convincing the American public to … Continue reading How NASA Sold Us The Moon

We all owe our EXISTENCE to lovely VOLCANOES, say boffins

Antarctica lava blasts kept Earth warm ‘n’ cozy during global cold snaps Pic Research by the British Antarctic Survey has found that volcanos played a crucial role in preserving life when our world went through one of its periodic ice ages. From time to time in Earth’s history, the planet cools and an ice cover extends from the poles to cover large sections of the planet’s surface. It’s even hypothesized that about 650 million years ago the entire world was covered with an ice sheet – the Snowball Earth scenario. Current scientific thinking is that as ice extends from the … Continue reading We all owe our EXISTENCE to lovely VOLCANOES, say boffins
