[Music] Hey, it's me, DTin. Welcome back to Smarter Every Day! The cat is disturbing homework time, so we're going to take a break and make an intro.

Every time I've observed a butterfly flying across a field, he looks like he's a very poor flyer. He looks like he's bouncing along, and because of the really large surface area on the wing and low mass, it looks like the wind's just making him flutter back and forth. He doesn't really have control over what he's doing.

But it wasn't until I recorded this next video with a Miro at 2,000 frames per second in the Amazon that I realized that I've probably been wrong this entire time.

All right, see if we can high-speed—what is this called? This butterfly? Uh, I believe it is [Music] Metha. Yep, I got it. Is it gone? [Music] Oh, oh, oh! [Music] It stayed in focus! Oh my [Music] God, dude, that was amazing!

All right, let's take this opportunity to change the battery since this one's low. Sure, that nuts J. You want some water? Fine, fine, of course you are. You don't need water, do you?

Derivatives of inverse functions | Advanced derivatives | AP Calculus AB | Khan Academy

So let’s say I have two functions that are the inverse of each other. So I have f of x, and then I also have g of x, which is equal to the inverse of f of x, and f of x would be the inverse of g of x as well. If the notion of an inverse function is comple…

The pre-equilibrium approximation | Kinetics | AP Chemistry | Khan Academy

The pre-equilibrium approximation is used to find the rate law for a mechanism with a fast initial step. As an example, let’s look at the reaction between nitric oxide and bromine. In the first step of the mechanism, nitric oxide combines with bromine to…

Solving equations by graphing: graphing calculator | Algebra 2 | Khan Academy

We are told we want to solve the following equation: that the negative natural log of 2x is equal to 2 times the absolute value of x minus 4, all of that minus 7. One of the solutions is x is equal to 0.5. Find the other solution. They say hint: use a gra…
