Genius of Einstein, Fourier key to new humanlike computer vision

Genius of Einstein, Fourier key to new humanlike computer vision: The heat-mapping method works by first breaking an object into a mesh of triangles, the simplest shape that can characterize surfaces, and then calculating the flow of heat over the meshed object. The method does not involve actually tracking heat; it simulates the flow of heat using well-established mathematical principles, Ramani said...

Einstein's theory applied to superconducting circuits

Einstein's theory applied to superconducting circuits: Horowitz and his research team found what could be called a gravitational model, or a gravitational dual — a dual description of a superconductor using gravity, black holes, and all of the traditional ingredients of general relativity. "This came as quite a surprise because this is a totally different area of physics, which is now being connected to this condensed matter area," said Horowitz.

Physicists Dispute Table-Top Relativity Test: Scientific American

Physicists Dispute Table-Top Relativity Test: Scientific American: The debate comes down to whether a fundamental atomic oscillation, based on the rest mass of a cesium atom, can be used as a clock. The table-top setup relied on an atom interferometer, which tracked the offset in oscillations, or phase difference, of the cesium atoms as they flew on paths of marginally different heights. But Blanchet's team argue that the phase difference between any two atoms due to the fundamental oscillation will always be zero, and therefore could never be used to detect a gravitational redshift.

They say that the Berkeley researchers were instead using their interferometer as an accelerometer to measure a different aspect of general relativity: the universality of free fall. That is no less interesting in its own right, but it has already been tested to greater levels of precision.

Einstein's sceptics: Who were the relativity deniers? - physics-math - 18 November 2010 - New Scientist

Einstein's sceptics: Who were the relativity deniers?: A few years ago, I had the opportunity to access papers belonging to the physicist Ernst Gehrcke, one of the most outspoken critics of Einstein in Germany. As I delved into the material he had neatly collected in banana boxes, a whole world of anti-relativity emerged from hundreds of pamphlets, thousands of newspaper clippings, and piles of letters from Einstein's opponents across Europe and the US.

I discovered that the group opposing relativity was much broader than many historians believed till now, and that their tactics had much in common with those used by creationists and climate-change deniers today. Their reasons for countering relativity were also more complex and varied than is usually thought. Even Einstein misjudged the motivations of many of his opponents.
