I may have to stop talking about sub-atomic physics as 'Alice in Wonderland' territory, and invoke Cinderella's glass slipper instead. I sense Derrida and Planck are going to collide quite soon now. There could be an interesting puff of something resembling smoke. The non-imaginary world inhabited by unwitting devotees of ontological realism will shrug its shoulders and carry on. -------- Forwarded Message -------- Subject: [LINK] Space-Time Crystals Date: Thu, 4 Mar 2021 07:51:04 +0000 From: Stephen Loosley <[email protected]> To: [email protected] <[email protected]> Space-Time Crystals .. https://is.mpg.de/news/world-s-first-video-recording-of-a-space-time-crystal “All crystals are a solid whose atoms or molecules are regularly arranged into a particular structure in space. And it is the same with space-time crystals: however, the recurring structure exists not only in space, but also in time. The smallest components are constantly in motion until, after a certain time, they re-arrange themselves into their original pattern again. https://youtu.be/kUY3TglEUCU World's first video recording of a space-time crystal Max Planck Institute for Intelligent Systems Periodic pattern consisting of magnons is formed at room temperature A team of researchers has succeeded in creating a micrometer-sized space-time crystal consisting of magnons at room temperature. With the help of an ultra-precise X-ray microscope, they were able to capture the recurring periodic magnetization structure in a movie. The research project “Real space observation of magnon interaction with driven space-time crystals” was published in Physical Review Letters: _______________________________________________ Link mailing list [email protected] https://mailman.anu.edu.au/mailman/listinfo/link -- Roger Clarke mailto:[email protected] T: +61 2 6288 6916 http://www.xamax.com.au http://www.rogerclarke.com Xamax Consultancy Pty Ltd 78 Sidaway St, Chapman ACT 2611 AUSTRALIA Visiting Professor in the Faculty of Law University of N.S.W.
