No, science requires much more work watching Cosmos, as evidenced by [Ast]’s adventures in analyzing data to measure the speed of sound with a microcontroller. After [Ast] built a time to ...

Venus Aerospace just tested a hypersonic engine that could someday enable aircraft to fly at five times the speed of sound or ...

Sound waves travel at approximately 750 mph at sea level, but slow down at higher altitudes. The speed of sound is called "Mach 1." Supersonic refers to speeds from Mach 1 to Mach 5 (1 to 5 times ...

A person fires a starting pistol. A distant observer stood 200 metres away (measured using a 20 m tape measure or trundle wheel) records the time between seeing the flash of light from the ...

But you may feel like you have a pretty intuitive understanding of fairly simple macro objects, for instance, a pole. So here's a question; when you take a long metal pole and push it at one end, how ...

US prioritizes hypersonic weapons. The AFRL contract covers a flight demonstration as well as the integration of Ursa Major’s ...

A2 is an unmanned, aircraft built by California-based firm Stratolaunch, founded by the late Microsoft co-founder Paul Allen ...

Japan has shown off a railgun it would use to shoot down hypersonic missiles. The weapon fires projectiles at 2,500 meters per second - seven times the speed of sound - enabling rapid engagement of ...

Although sound travels quite fast, it is still possible to measure its speed in air. To do this, you need to measure the time it takes a sound to travel a measured distance. To reduce errors ...

Mach 10, ten times the speed of sound, would be about 7,600 mph. It hasn't been reached yet, but could a pilot even survive ...
