Ever wonder what a vinyl record looks like under an electron microscope? Okay, probably not. Luckily, there’s people who do, including Chris Supranowitz, who created a number of electron microscope images for a course at the University of Rochester.
Here’s a photograph of the record grooves captured by Supranowitz at 500x magnification. Those dark chunks you see are dust particles.
This one was shot at 1000x magnification. The record begins to look like the Grand Canyon.
These images were created in the Spring of 2005 for the course Opt 307/407: Practical Electron Microscopy and Advanced Topics. Other projects used the electron microscope to examine such things as snowflakes and bird feathers.

Ive never seen the gramophone as an invention. Ive seen it more as a discovery of how to reproduce sound. Also more than one inventor discovered it at the same time so I believe it to be a universal knowledge known elsewhere in this great Universe
