AI Thread Summary
Mersenne's Law describes the relationship between the fundamental frequency of a vibrating string and its tension, length, and mass per unit length. It states that the frequency is proportional to the square root of the tension and inversely proportional to both the length and the square root of the mass. The discussion also touches on Mersenne primes, highlighting the connection to the mathematician Marin Mersenne. Additionally, there is a reference to Pythagoras, suggesting he expressed similar concepts regarding frequency and vibration. Understanding these principles is essential for exploring the mathematical foundations of sound and music.

Can someone please explain what Mersenne's Law is?

Above from a google search - you can get a lot more by doing it yourself.

Interesting that Mersenne gets the credit for that. Pythagoras said something very similar if I recall.
 
I am following someone on Youtube who has built a rocket shaped (4 proprllers) drone for the world speed record ... He was having problems with internal heat from electical control gear and battery inside the sealed rocket (about 1kw waste heat) Speed is 500km/hr , I suggested a 4mm hole in the tip of the nose and 8mm hole at rear which should alow sufficient air cooling .. I said this will increase thrust because the air exiting is hotter .. a bit similar to a ram jet ... was I correct...
