Magnetic Stirrers

Magnetic stirrers are super awesome. I wonder what it would be like to stir everything with a magnetic stirrer rather than using a spoon or stick or something. Though of course, for drinkable things, the magnet would have to be used just for drinks, because using the same magnet as ones used for chemistry lab experiments would be dangerous.

Uncertainty

I am uncertain as to how interesting this is because I made this in about 10 minutes. However, I am quite certain that I find it interesting that there is an equation for uncertainty. And here is a Wikipedia page about it. There’s probably an equation somewhere for how uncertain you are about the accuracy of the uncertainty calculated from that equation.

Gravitational Potential Energy

Please note that this flash lacks a punchline because I was too lazy to think of one. In regards to the actual discussion in the flash, it may be incredibly unlikely, but what would happen?! I would like to know the answer, and hopefully someone can answer it!!

Ideal Pulleys

Someone asked something like this and it was an actual response. Also suggested was the idea that the pulley and string were made of light and this was on an atomic level but I’m not sure if that would work at all. But the only logical solution is that it is magic.

Entropy

This daily flash is an example of the second law of thermodynamics. If anyone tells you are messy or disorganized, you can tell them that you are just obeying the second law of thermodynamics and that your entropy is not at equilibrium and will tend to increase anyway so it is inevitable. Entropy!!
