The never-ending conundrums of classical physics. During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes.
In the old physics, mass and energy were separately conserved; particles’ positions and momenta could be arbitrarily specified; gravity acted instantaneously at a distance; the equality of gravitational and inertial mass was just a coincidence; and there was no speed limit. All these ideas and assumptions are now known to be in some way untenable. They're either inaccurate or theoretical dead-ends. To put it plainly, classical physics is wrong. As such, there's really only one thing to do—physicists have since abandoned the old, mistaken ideas, right?
Not quite. Weak electrical field found to carry information around the brain. In a development that could lead to improved understanding of memory formation and epilepsy, scientists have discovered a new way information may be traveling throughout the brain.
The team has identified slow-moving brainwaves it says could be carried only by the brain's gentle electrical field, a mechanism previously thought to be incapable of spreading neural signals altogether. "Researchers have thought that the brain's endogenous electrical fields are too weak to propagate wave transmission," says Dominique Durand, professor of biomedical engineering at Case Western Reserve University. "But it appears the brain may be using the fields to communicate without synaptic transmissions, gap junctions or diffusion.
" What led Durand and her team of researchers to this conclusion was the recording of neural spikes traveling too slowly to be carried by conventional means, indicating something else was at play. Not Just White Noise: The Many Colors of Sound. Most people are familiar with white noise, that static sound of an air conditioner that lulls us to sleep by drowning out any background noise.
Except technically, the whirl of a fan or hum of the AC isn’t white noise at all. Many of the sounds we associate with white noise are actually pink noise, or brown, or green, or blue. In audio engineering, there’s a whole rainbow of noise colors, each with its own unique properties, that are used to produce music, help relaxation, and describe natural rhythms like the human heartbeat. German Chancellor fires hydrogen plasma with the push of a button. Pics and video Angela Merkel has witnessed the first hydrogen plasma being created by the Wendelstein 7-X fusion reactor experiment as part of Germany's push to take the lead in future power generation.
Doubts have been raised about a Cambridge professor’s acclaimed battery breakthrough — Quartz. There is a man waiting for the doctor and his time is running out.
It is late evening, just over an hour after the doctor first groped for his ringing phone. “Can you help us?” The woman on the other end had asked, her voice breaking. Now, preparing for the procedure, the doctor is alert. He moves quickly. The doctor sits over the patient ready to perform the surgery. Having verified that the procedure was a success, the doctor carefully sutures the patient back up. The patient is dead. He has, in fact, been so for a while–over 30 hours, according to his chart–but some of him survives.
BILL GATES INTERVIEW: Energy miracle coming. Mike Nudelman / Business Insider The most remarkable thing about meeting Bill Gates in person is beholding his mental map of the world — how advances in technology, the well-being of humanity, and the fate of our world are all intertwined.
Tech Insider met with Gates on Monday to talk about his 2016 annual letter, in which he discusses the balance of bringing electricity to the billion people who don't have it and finding power sources that don't kill the earth. Scientists Turn Nuclear Waste Into Diamond Batteries - Slashdot. Scientists at the University of Bristol have found a way to convert thousands of tons of nuclear waste into man-made diamond batteries that can generate a small electric current for thousands of years.
New Atlas reports: How to dispose of nuclear waste is one of the great technical challenges of the 21st century. The trouble is, it usually turns out not to be so much a question of disposal as long-term storage. Disposal, therefore is more often a matter of keeping waste safe, but being able to get at it later when needed. Launch set for GOES-R satellite capable of 30-second weather updates. NASA meteorologists have given a 90 per cent chance of good weather for the launch of the revolutionary Geostationary Operational Environmental Satellite – R Series (GOES‑R) on Saturday.
GOES-R is possibly the most advanced weather satellite ever produced, capable of providing high-definition, multi-spectrum snapshots of weather systems every 30 seconds, as well as keeping an eye on the Sun to spot solar flares that could be heading our way. The one-hour launch window begins at 1742 EST (2242 GMT) for the Atlas V 541 rocket.
“Positioned over 22,000 miles above the Earth, GOES‑R will take weather observation to new heights. An adhesive that holds tight in cold, gets stronger in heat. Researchers have developed a new dry adhesive that not only bonds in extreme temperatures, it even gets stronger as the heat goes up.
The gecko-inspired material maintains its hold in extreme cold and actually gets stickier in extreme heat. Building on previous research, a team of engineers from Case Western Reserve University and Dayton Air Force Research Laboratory created a double-sided tape made of carbon nanotubes that they claim would lose no traction whether applied to cold liquid nitrogen or hot molten silver.
