Welcome to c/science_memes @ Mander.xyz!

A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules

  1. Don't throw mud. Behave like an intellectual and remember the human.
  2. Keep it rooted (on topic).
  3. No spam.
  4. Infographics welcome, get schooled.

This is a science community. We use the Dawkins definition of meme.

I mean, it would be some 25 years until the radio was invented. And Hertz' machine required a 30kV spark on a 2.5m meter long antenna with 2 solid 30cm zinc spheres, and his transmission range was something like "barely down the hall".

Not the most practical method.

I'm sure someone thinks it's perfect for their use case, semi relevant xkcd:

At least physics will never get patched. The spark device with zinc spheres will always do that thing.
