Why Do We Dance To Music?
Why do we dance? We dance to music because of neural connections in our brain. These connections link the part that perceives music, the auditory cortex to the regions that help us move, the motor regions. We might have started creating...

Why Do Power Lines Buzz?
The buzzing sound that power lines produce is caused by corona discharge. Corona discharge is an electrical discharge that occurs when a fluid (like air) surrounding an electrically-charged conductor becomes ionized. In simple terms, its...

Why Do Our Faces Look So Weird In The TikTok Inverted Filter?
TikTok's inversion filter reverses a facial selfie and shows you what your face looks like when its not reflected in a mirror. Or, in other words, how the world sees you and not what the mirror shows. Thus, the effect of this reversal is...

Kinetic Molecular Theory and the Ideal Gas Laws
I bet many of you think that the ideal gas law must prohibit passing gas on the elevator. That's a very good guideline, but there are other important laws we must know! Let Professor Dave run you through the details.

Ideal Gas Problems: Crash Course Chemistry
We don't live in a perfect world, and neither do gases - it would be great if their particles always fulfilled the assumptions of the ideal gas law, and we could use PV=nRT to get the right answer every time. Unfortunately, the ideal gas...

Why Do Tightrope Walkers Carry Long Poles when Walking on A Rope?
Carrying a pole helps the walker increase their rotational inertia, which aids in maintaining stability while walking over the narrow rope. The pole also adds more weight below the center of gravity of the walker, which is another bonus...

Practice Problem: Graham's Law of Effusion
We know that molecules will travel at an average velocity that is inversely proportional to their molar mass. This means that lighter gases travel faster. We can relate the rates of effusion for two gases using Graham's law, and we can...
