In ~90% of the time, when people are talking about energy, they should actually be talking about entropy.
There is a wonderful new video about "The Most Misunderstood Concept in Physics" - Entropy
by @veritasium
Though, actually I would say ENERGY is the most misunderstood concept and as a consequence ENTROPY is the most neglected one.

Simulation is the best way to learn anything, and I would highly recommended using it to learn why it's cold up on mountains.
Why is it really cold in the mountains?
It sounds like a simple question, but it is actually really not that trivial.
I did a lot of digging, and came up with a few simple interactive simulation models to illustrate some key concepts, that lead to cold mountains. #ScieneTwitter
You can find the full story on my website:

In this simulation, for example, white dots represent visible light, and the orange dots represent heat radiation. The heat radiation is stochastically emitted based on the temperate of each slab, which is indicated by its color.

Wow... @hankgreen just commented my latest video about AI and temperature. This is so exciting!

In my new video I explore how you can use the new AI #ChatGPT and #threejs to create 3D animations. It is wild!

What a beautiful example of a Monte Carlo simulation!
My new story out today is about a technological revolution that has made it harder for politicians to get away with gerrymandering. But some fear it could also threaten minority voting rights.

In case you are interested, I used @openmm_toolkit to run the #Simulation , and @matplotlib for plotting.

Also, check out this amazing video by @smartereveryday with Incredible slow motion footage of whips breaking the sound barrier!

As this progresses towards the tip, more and more kinetic energy is concentrated in fewer and fewer beads, leading to the highest velocities in the tip!
because they are moving too fast in terms of angular velocity compared to the outer beads. In the process they transfer kinetic energy to the outer beads.
So what is going on? If you look at the velocities of the different beads over time, you can see that initially all beads accelerate equally. Then, one after another, the inner beads are slowing down,
