How does wood hardness affect the sound of a TT on a wood TT platform?

Electron microscope?

Gravitational waves detectors?

nanotube resonator? for measuring down to yoctogram (one septillionth of a gram – 10 to the -24th grams) or the mass of a single proton.

Ok i'm running out of ideas.

I was just discussing that a couple weeks ago on these fora. Coincidence? 😳

Back from Google. Global earthquake detection. The glass (silica fibers) are 400microns thick so chosen as they are immune to expansion and contraction from temperature changes. This thermal noise would impact negatively on measurements.

The wood in a plinth of turntables has much more influence for example than the wood used for making table tennis rackets.
Have you ever tried to use table tennis rackets with identical rubber but different woods?

I have been trying for a long time and there are macroscopic differences.
I believe that for the plinths the same thing is the same, the problem is that nobody has ever built plinths with different woods and then made tests and measurements with laboratory instruments.
