Did anything else break the sound barrier prior to 1947? While bullets and cannonballs had exceeded the speed of sound for years, conventional wisdom held that humans could not exceed it. Further, there was skepticism that aircraft propulsion systems could ever propel an aircraft to the speed ...
, an Air Force test pilot, broke the sound barrier in an X-1 rocket plane flying over Victorville, Calif. Although Yeager himself didn't become part of the Mercury manned spaceflight program, he served as a prototype for the kind of person NASA felt could succeed as an astronaut. By the...

Cannabis plants grow very fast in a short amount of time, and need a lot of energy from the light to grow and produce buds. In the wild, a cannabis plant can grow to the size of tree in less than a year, and it uses energy from light to power that growth. Many new growers who...
Observation 2:This lock-free,volatilebusiness is obviously fishy. The programmer clearly expects things to happen in a very specific, precise order. If we could somehow violate those assumptions, it may lead to a race condition. It's a common misconception thatvolatileacts like a barrier. Althou...
through an electric arc. The breakthrough discovery was that charging the gas with an electric current formed a barrier around the weld, which protected it from oxidation. This new method -- called plasma arc cutting -- made for much cleaner lines at the joints and much sturdier construction....
But — how do they cross the barrier? How does an ion enter or exit a cell? Well, that’s where ion channels come in. As the name implies, these are channels located in the membrane that grant passage to specific kinds of ions. (Note: In most cells, the potassium channels outnumber...
It is recommended that you keep feeding to a minimum during travel. Be sure to feed them their regular pet food and resist the temptation to give them some of your fast food burger or fries (that never has a good ending). Don't Leave Them Alone Never leave your pet unattended in a ...
Scientists at the Harbin Institute of Technology in China and Northumbria University recently developed a low-power system to control the synaptic devices in the bionic eyes, with lead professor Professor PingAn Hu describing it as a ‘significant breakthrough’ according to Northumbria University’s ...
One day, perhaps, she’ll want to know. “You know why—right?” I holler. “He broke the sound barrier.” “No, I mean, you know why anyone knows Chuck Yeager broke the sound barrier, or cares?” He shakes his head. He’s busy declaring to the airport authorities his improbable ...
