Think of Schrödinger’s cat, the standard paradox for illustrating this particular aspect of quantum theory. A cat in a closed box that also contains a vial of poison could be thought of as either alive or dead, so long as we can’t see inside the box, as National Geographic has explained. To see that the cat is not occupying both states simultaneously, but either one or the other, we need to directly observe it by looking inside the box.
“For invisibility cloaking, we need to both transmit and manipulate light in very precise ways, and that’s very difficult today,” said Rachel Goldman, professor of materials science, engineering and physics.
Electric eels generate voltage through long stacks of thin cells that run end-on-end through their bodies. Called electrocytes, these cells create electricity by allowing sodium ions to rush into one end and potassium ions out the other, all at the same time.
Breakthroughs Could Make Commercial Laser Nuclear Fusion Through Billion Times Improvements In Yield
A research paper claims experimentally confirmed reaction gains one billion times higher than the classical values, placing it far ahead any DT fusion approaches. Lasers are being demonstrated as more and more important in scientific research and in the access to new processes.
Researchers 3D-print WiFi-connected Objects That Don’t Need Power – The Objects Contain Antennas That Reflect Surrounding WiFi Signals.
“But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That’s something that no one has been able to do before.” To do this, the team used things like 3D-printed springs, gears and switches that could be used to translate motion into antenna-transmitted information.
There are other differences. While traditional 3D printers build parts from computer files, the cold-spray machine uses digital scans of actual jet engine parts to accurately reconstruct the broken part.
