Even Concorde, which topped out at a supersonic 1,350 mph (2,172 kph), was shut down after 27 years due to safety issues and cost concerns [source: Novak]. Physics is a harsh taskmaster. As a plane speeds toward the sound barrier, air stops "getting out of the way" and compresses...
Now, in 2023, the latest X-plane – the X-59 Quiet SuperSonic Technology (QueSST) aircraft – is aiming to repeat a feat achieved by the first X-plane – break the sound barrier again. Only this time, if all goes to plan, nobody on the ground will notice. 现在,2023年,最新的X系...
More importantly, it was new against Chevy's second facelift in two years. Unfortunately, the Fords had some structural weaknesses (principally roof panels) and were prone to rust, one reason you don't see that many today. But though Plymouth arguably won the styling stakes with its finned ...
The moment an aircraft’s speed exceeds the speed of sound, it is said to have broken the sound barrier. At what speed do you break the sound barrier? The speed at which you break the sound barrier depends on many conditions, including weather and altitude. It’s approximately 770 mph or...
A '49 Ford couldn't quite reach 100 mph, but hopping up the flathead V-8 was still simple, cheap, and easy. Multiple carburetors, headers, dual exhausts, and other "speed parts" were as close as local auto stores. Though Ford briefly considered retaining it, the low-selling Sportsman ...
The fuel is partially burned in a pre-chamber to produce high pressure, hot gases that drive the turbo-pumps (fuel pumps). The fuel is then fully burned in the main combustion chamber and the exhaust gases (water vapor) leave the nozzle at approximately 6,000 mph (10,000 km/h). Each...
Many Montrealers, especially those in the travel industry, are fully bilingual so there's hardly a language barrier. But a smile and a salut, bonjour, merci (hello, good day, thank you) on your part go a long, long way. The best tip of all -- Montreal is a treasure waiting to be...
To become the fastest sailor in the world, he’s going to have to break through the nautical equivalent of the sound barrier—the so-called 50-knot barrier (about 57 miles per hour). The name is something of a misnomer, because the barrier can drift slightly higher or lower depending on...

"Too much retinol will produce too much cell division, causing large numbers of immature cells to rise up to the surface without the proper bonds to hold them together." When too many cells rise up to the surface, the skin can start to peel, as the lipids and bonds that are needed to...
