So called fat tailed distributions are a random walk. It’s just that their sample distribution is a power law (no mean hence fat tail). Example of which is a Lévy flight: a random walk with a heavy tail.
Yep any size particle should. But gravity is described by classical physics through general relativity. When you have situations of very small quantum scales and large gravitational fields both general relativity and quantum field theory don’t work well together. This is a big problem in physics.

This company did a slight pivot to building autonomous collectors anchored in rivers which have the most plastic dumped into them leading to the ocean.
Peer-review is free. Editing and Lay-out etc is done with the journal (not much though as they supply latex templates for your work). So there is some cost associated with this.
That sounds very inefficient. Here’s something that gets good results quickly. Tie a string/top to a filled 2L bottle. Attach the other end of the rope to the center of a short wooden pole. Wind up the bottle. Wind down the bottle. Repeat ad infinitum. Quick and easy.
There is so much on the plate of the academic that to learn yet another piece of software — like docker which can be trying at the best of times — is yet another straw that can break the back.
You do realize that often artist don’t physically make a large portion of larger art pieces. Nor do they set them up in galleries it is often done by teams but the artist gets the sole credit.
