Leo Szilard along with Albert Einstein started the manhatten project. This infor/thermos connection doomed Maxwell's demon!<br /><br />Scientists in 2015 showed that entanglement increases the free energy available.flashgordonhttps://www.blogger.com/profile/06494729248223186195noreply@blogger.comtag:blogger.com,1999:blog-5350615302660579874.post-85678723478794806392016-04-10T16:03:52.297-07:002016-04-10T16:03:52.297-07:00I posted relatively early in this blog Spectr R, o...I posted relatively early in this blog Spectr R, or RadioAstron, a Russian space orbiting radio interferometer telescope. It orbits almost to the length of the moon, and it combines(interferometry) it's signals with radio telescopes here on Earth, to make a radio telescope diameter almost the Earth/Moon distance. <br /><br />It's been cranking out papers. I've heard they've done some data/imaging of SagA, our galactic nucleus where a Black-Hole resides. I would think a surprise announcement is immenant.<br /><br />But anyways, one recent scientific paper that has come from RadioAstron, is finding trillion degree gas around a quasar. This really isn't that surprising; but, it took RadioAstron to be able to measure it to a trillion degrees, and not say, a billion degrees which was the previous measurement. One wonders what the temperature would be measured with an even more sensitive and larger radio interferometer!flashgordonhttps://www.blogger.com/profile/06494729248223186195noreply@blogger.comtag:blogger.com,1999:blog-5350615302660579874.post-9917181868893464242016-04-10T15:58:52.058-07:002016-04-10T15:58:52.058-07:00Some more exciting science/tech news I didn't ...Some more exciting science/tech news I didn't get around to posting in the main article . . .<br /><br />Scientists/engineers first began to use terahertz radiation in the 2000s. It was one of the big discoveries next to perfect lenses. For some strange reason, it took microtechnology to be able to use terahertz radiation. Terrahertz falls between infrared and microwaves. <br /><br />- Here's a quote right out of the wiki, "Similarly, the generation and modulation of coherent electromagnetic signals in this frequency range ceases to be possible by the conventional electronic devices used to generate radio waves and microwaves, requiring the development of new devices and techniques."<br /><br />Here's an article where they created a terahertz lens, http://esciencenews.com/articles/2016/03/14/researchers.develop.new.lens.terahertz.radiation?utm_source=twitterfeed&utm_medium=twitter&utm_campaign=Feed%3A+eScienceNews%2Fpopular+%28e%21+Science+News+-+Popular%29flashgordonhttps://www.blogger.com/profile/06494729248223186195noreply@blogger.com
