Planck's law … fails … - SlideRule - 10-28-2019 11:48 AM Excerpts from A Fundamental Physics Law Just Failed a Test Using Nanoscale Objects, MIKE MCRAE, 5 SEP 2018 "Planck's law of radiative heat transfer has held up well under a century of intense testing, but a new analysis has found it fails on the smallest of scales. Exactly what this means isn't all that clear yet, but where laws fail, new discoveries can follow. Such a find wouldn't just affect physics on an atomic scale – it could impact everything from climate models to our understanding of planetary formation. The foundational law of quantum physics was recently put to the test by researchers … Not only does the law fail, the experimental result is 100 times greater than the predicted figure … It's important to experimentally measure something, but also important to actually understand what is going on. … This hyper-efficient rate of energy transfer could feasibly change how we understand heat transfer in the atmosphere, or in a cooling body the size of a planet. The extent of this difference is still a mystery, but one with some potentially profound implications .… This research was published in Nature." BEST!
