10) Here's how you convert Cartesian (rectangular) to Polar Coordinates

In short, rectangular coordinates and polar coordinates are two ways that you can use two numbers in order to locate a point on a specific plane. Rectangular coordinates are in the form (x,y), where 'x' and 'y' are the horizontal and vertical distances from the origin. Polar coordinates are in the form: (r,q), where 'r' is the distance from the origin to the point, and 'q' is the angle measured from the positive 'x' axis to the point. Sound confusing? This gif may help.

9) This is how Exterior Angles of Polygons work

This one really isn't that difficult: They add up to 360 degrees.

8) This is a Hyperboloid made up of straight lines

A hyperboloid is a quadratic surface. The one-sheeted hyperboloid is a surface of revolution obtained by rotating a hyperbola about the perpendicular bisector to the line between the foci, while the two-sheeted hyperboloid is a surface of revolution obtained by rotating a hyperbola about the line joining the foci. That is, admittedly, a lot of complicated math. Here's a simpler view.

6) This is how White Blood Cells keep you safe

White blood cells help us fight off infections and diseases by literally chasing down and attacking bacteria, viruses, and germs that invade our bodies. In this video, a white blood cell chases and engulfs a bacteria. Make sure you watch until the end.

5) This is Earth’s ice and vegetation cycle over a year

Each year, as our planet revolves around the Sun, ice forms and recedes. This happens not because of the path that we follow around the Sun, but because of the tilt of the Earth. You can see the impact that this has with your own eyes in the gif below.

4) There is flammable matter in smoke

Smoke isn't just nothingness, obviously. It's matter. It burns.

2) This is vortex pinning

Here, a superconductor levitates over a magnetic track. A superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance.

1) This is how Tension works in relation to falling objects

Watch a slinky fall to the Earth, and understand how tension works in relation to gravity. This video was filmed with a slow-motion camera that records 300 frames per second. Learn how the physics works in the fantastic video below the gif.
