Can Humans Even Reach 1% the Speed of Light Ever?

Posted by in category: transportation

While 1% of anything doesn’t sound like much, with light, that’s still really fast — close to 7 million miles per hour! At 1% the speed of light, it would take a little over a second to get from Los Angeles to New York. This is more than 10,000 times faster than a commercial jet.

Bullets can go 2,600 mph (4,200 km/h), more than three times the speed of sound. The fastest aircraft is NASA’s X3 jet plane 0, with a top speed of 7,000 mph (11,200 km/h). That sounds impressive, but it’s still only 0.001% the speed of light.

Pitt Scientists who Regrew Retina Cells to Restore Vision in Tiny Fish set their Sights on Humans

Posted by in category: quantum physics

(PhysOrg.com) — By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it’s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life.

Chip Industry May See Overcapacity in 2023

Posted by in categories: computing, government, mobile phones

“The industry will see normalization and balance by the middle of 2022, with a potential for overcapacity in 2023 as larger scale capacity expansions begin to come online towards the end of 2022,” the research firm predicts.

Indeed, major semiconductor makers—including Intel, TSMC and Samsung—have all boosted investment in expanding chip capacity amid the current shortage. At the same time, the US government wants to spur more domestic chip manufacturing with billions in potential funding.

The big question is which sectors will see the semiconductor supplies improve to the point of overcapacity. Current shortage have ensnared a wide range of products, including PCs, graphics cards, video game consoles, in addition to cars, smartphones, and smart home devices.

Physicists Explain How Human Eyes Can Detect Quantum Effects

Posted by in category: quantum physics

(PhysOrg.com) — By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it’s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life.

The group of physicists is from the University of Geneva, and includes Pavel Sekatski, Nicolas Brunner (also from the University of Bristol), Cyril Branciard, Nicolas Gisin, and Christoph Simon. In their study published in a recent issue of Physical Review Letters, the scientists theoretically show how human eyes can be used to detect a large Bell inequality violation, which proves the existence of .

As the physicists explain, the key to achieving detection of quantum effects is to use the process of quantum cloning by stimulated emission. Recently, using quantum cloning, researchers in Rome have experimentally created tens of thousands of clones starting from a single-photon. Then, by amplifying one photon of an entangled pair, the researchers managed to demonstrate entanglement. In order to do this, specific detectors are required, which can distinguish two orthogonal amplified states with a high success rate.

Amprius Reports Extreme Fast Charge Battery: 0–80% In 6 Minutes

Posted by in categories: energy, nanotechnology

Amprius Technologies announced that its lithium-ion battery cells with silicon anode (Si-Nanowire platform) achieved a breakthrough fast charging capability of 0–80% state-of-charge (SOC) in just 6 minutes (10C current).

The capability of extreme fast charging has been validated and confirmed by Mobile Power Solutions for three 2.75 Ah sample pouch cells (see report here). It actually took less than 6 minutes to achieve 80% SOC.

0–70% charging takes less than 5 minutes, and 0–90% is usually above 8 minutes. Then, the charging rate is much slower, so 100% is achieved after 25–27 minutes (90–100% takes 17–19 minutes).

Inside Clean Energy

Posted by in categories: energy, sustainability, transportation

The price of the batteries that power electric vehicles has fallen by about 90 percent since 2010, a continuing trend that will soon make EVs less expensive than gasoline vehicles.

This week, with battery pricing figures for 2021 now available, I wanted to get a better idea of what the near future will look like.

First, the numbers: The average price of lithium-ion battery packs fell to $132 per kilowatt-hour in 2021, down 6 percent from $140 per kilowatt-hour the previous year, according to the annual battery price survey from BloombergNEF. The new average is a step closer to the benchmark of $100 per kilowatt-hour, which researchers say is the approximate point where EVs will cost about the same as gasoline-powered vehicles.

Nuclear Fusion: Why the Race to Harness the Power of the Sun Just Sped Up

Posted by in categories: computing, physics

A nervous excitement hangs in the air. Half a dozen scientists sit behind computer screens, flicking between panels as they make last-minute checks. “Go and make the gun dangerous,” one of them tells a technician, who slips into an adjacent chamber. A low beep sounds. “Ready,” says the person running the test. The control room falls silent. Then, boom.

Next door, 3 kilograms of gunpowder has compressed 1,500 liters of hydrogen to 10,000 times atmospheric pressure, launching a projectile down the 9-meter barrel of a two-stage light gas gun at a speed of 6.5 kilometers per second, about 10 times faster than a bullet from a rifle.

On the monitors the scientists are checking the next stage, when the projectile slams into the target—a small transparent block carefully designed to amplify the force of the collision. The projectile needs to hit its mark perfectly flush. The slightest rotation risks derailing the carefully calibrated physics.
