Adam Savage builds a brachistochrone curve, which is the same curve as an Isochronous, just with potentially different starting/ending points, with Vsauce's Michael Stevens. It's a pretty bizarre phenomenon: https://youtu.be/skvnj67YGmw https://youtu.be/skvnj67YGmw
- agumonkey 8y agoThey should build tautochronous pendulums. Or just add a spring bouncer on the end of the tracks so to enjoy multiple simultaneous bounces of different heights.
- monochromatic 8y agoFor small displacements, pendulums are already approximately isochronous.
- tprice7 8y agoHence pendulum clocks.
- pantalaimon 8y agoOne of the first definitions of the meter was a pendulum with a period of 1s afaik
- hexane360 8y agoSurely you mean 2 seconds? T = 2*pi*sqrt(L/g) = 2*pi*sqrt(1 m / 9.81 m/s^2) = 2.01 s
