Everybody's physics
Give me a moment of your day, and let me put a picture in your mind. Imagine you and a friend each have a soup in a plate, and each soup has two carrot pieces, one potato and not so much broth in it. You are bored, it is a slow afternoon, so you decide to perform a little experiment.
This post is a continuation of our last post on chaos. We therefore recommend you to read that one first, but it’s by no means necessary.
Time only moves forward – this is what we experience in our everyday lives. Often, people connect this to the fact that there are clearly processes in nature which cannot be undone: when you boil an egg you can not make the egg-white transparent again, your coffee is very unlikely to go back into the coffee powder, which will never become a full bean again itself.
Science can be sometimes daunting for the unexperienced. Have you ever seen a scientific talk, or read a paper? There tends to be a lot of jargon flying around, circling the speaker to then buzz aggressively around the audience before it goes out the windows into the oblivion of the coffee break.

We really should have started with some fancy quote, spoken in the past, and reverberating into the ages to come. But we didn’t. So let’s start instead with a small experiment. Fill a cup with something. No, not coffee, we know you were thinking about it. Something clear. You need to see through it. You also need to have some little pieces of something floating homogeneously around in your cup, like chia seeds once they are really squishy, or that weird aloe drink they sell at the supermarket. The latter, in fact, proves to be the best for this experiment.
