Integrating Factors

?=?e^[P(x)]dx (Though Wikipedia appears to use different variable names). This math pun was a result of me studying for a differential equations exam that I have tomorrow.

Retrievers

Last Wednesday in chem lab, after using the magnetic stirrer, I forgot the magnet was still in the beaker, so I accidentally dumped it into the chemical waste storage along with the rest of the contents of the beaker. I heard the sound of it falling in, and then I thought “did I really just do that?” and so later I had to use the retriever to get it back from the chemical waste storage container. But this week, I actually remembered to take the magnet out of the beakers before dumping the contents, hooray!

Also, this is relevant to the daily flash.

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!!
