Sprinter vs. Marathoner

Sprinter vs. Marathoner

We all now that a sprinter and a long distance runner will both train in different ways, but maybe not exactly why and how. This video does a great job of showing us the different kinds of muscles we can work out and how they help us.

Stop the phantom traffic jams!

Stop the phantom traffic jams!

Phantom traffic jams have the unique effect of both fascinating and infuriating me. I always knew there had to be some pseudo-scientific or mathematic reason for it but I never took the time to figure it out. Thankfully last night I stumbled upon some videos that explain the very phenomenon. This is the kind of stuff they should teach in driving class so people don’t lose their minds on their morning commutes.

Gravity Visualized

Gravity Visualized

These were always my favorite kinds of lessons in school. I think there’s something about getting up and watching something happen that kicks your mind out of bored at a desk mode and in to a more engaged and interested mindset. I never took a physics class, so I don’t have much of an understanding of this lesson, but I do know that something like this would have gotten me very excited to learn that day.

When water flows uphill.

When water flows uphill

I love it when people use science to create things that don’t seem physically possible. I think we all do. Using something called the Leidenfrost Effect, these students have been experimenting with ways to make liquids move up inclines. It’s really not that magical when they explain it but it still doesn’t fail to mesmerize.

Circuit Scribe, the new way to teach and use circuits.

Circuit Scribe, the new way to teach and use circuits.

This is one of the cooler products I’ve ever come across while looking for these videos. I’ve never really learned much about electronics or circuits, but I feel like this pen would be quite nearly the perfect tool to use to start to learn about that world. This thing could be invaluable to teachers of certain subjects in the future.

Astronaut tries to pick up hammer

Astronaut tries to pick up hammer

I never thought I’d post a video of such a simple action, but I also never thought I’d actually see a video of something like this happening on the moon. This is apparently video of American astronaut Charles Duke trying to overcome a simple problem in an unusual setting.

Turning your smartphone in to a microscope

Turning your smartphone in to a microscope

This kind of experiment really blows my mind. You can take what is one of the simplest cameras we have around these days and basically add one accessory to it to turn it in to a serious microscope.
