I’ve seen these little spherical magnets before, but had no idea they were called Buckyballs. I thought it might be an English thing at first but apparently it’s an actual brand name. Anyways, get yourself some Buckyballs, copper wire, a battery, and a strong washer-shaped magnet and you[...]

Incredible jumping robot
I’ve now realized that every movie in which the robots are nothing more than metal humans is very silly. There’s no reason to base a robot’s mobility on normal human limitations. That is unless we don’t want them to rise up and overtake us. Unfortunately many of the advanceme[...]
Why dogs might be the key to learning about learning.
A bit of a longer video today, but it’s worth it. Neil deGrasse Tyson takes us through an in-depth look as to how dogs might be a key figure in discovering more about the learning process. There’s something about dogs that make them unique. They care about humans and what humans want the[...]
Breathtaking video of Shuttle Discovery launch
If you got a chance to see a shuttle launch, you’re a very fortunate person. Even this HD video is amazing to watch, I can’t imagine what it’s like in the future. Hopefully seeing a launch of whatever takes us to space in the future will be as common as seeing an airplane takeoff, [...]

Different Sizes of Infinity
Don’t you love how math is so in-depth that you can study sets of numbers the same way you can study numbers? This video shows how different sets of infinity can be determined to have different sizes between themselves. I wonder when in math studies you learn this stuff. I haven’t gotten[...]
Enormous K’nex contraption
There are plenty of videos or Rube Goldberg-like machines on the internet, but this is the first one I’ve seen made entirely out of K’nex. Apparently took them a year to build but I can’t even imagine the planning that went in to this kind of thing. Well done these guys, they deser[...]
Area of a Circle – A Proof Without Words
A quick and very interesting video here that you might need to watch a couple times before you fully understand. Basically proving the formula for area of a circle by turning it in to a triangle. Another reason it would be good for math books to be animated.[...]
5 Historical Misconceptions
There are always little incorrect facts that are constantly streamed through our education and occasionally you have moments in your life when you realized you had something completely wrong. This video is trying to do that for you. It features some interesting misconceptions and gets to the bottom [...]
The left and right brain
Here’s a pretty interesting video in which Alan Alda takes us through a few experiments with a man who had the two halves of his brain separated. It can really give you a good idea of the way the two brains work together and the difference between someone with a normal brain and one that [&hel[...]
