The lads at How Ridiculous are back at the drop tower.
On the morning of December 1st, 2020, one of the most iconic astronomical instruments in the world collapsed. The Arecibo Telescope was not only one of the largest radio telescopes in the world, it was also a fascinating problem in structural engineering. Its loss was felt across the world. Practical Engineering provides a quick lesson on radio telescopes, a summary of the failure, and some discussion about the engineering lessons learned in the wake of the event. I hope that eventually, they can replace the telescope with an instrument as futuristic and forward-looking as the Arecibo telescope was when first conceived. It was an ambitious and inspiring structure, and we sure will miss it.
Gav of The Slow Mo Guys plays a wine glass’s least favorite sound at extreme volumes and captures the results at 187,500 fps. That’s around 7500x slower than you can see with your own face.
How high will it bounce?
A bold move, to be sure. This guy has a Ph.D in physics. Says Derek, “A UCLA Physics Professor bet me $10,000 that my video about going downwind faster than the wind was wrong.”
