This week Hank introduces skepticism, exploring everything from the nature of reality through the eyes of a 17th century philosopher and, of course, The Matrix.

We make a Cartesian diver using a drinking straw and sticky tack. When the diver is placed in a sealed bottle of water it can be controlled by squeezing and releasing the bottle, which makes it rise and fall within the water. Physics -...

The development of the Cartesian Coordinates system, and linear and non-linear equations, by the mathematician who fled the small hometown that now reveres him. Maths - History Of Maths A Twig Math Film. Reinforce and extend the learning...

In this latest episode of What the Theory? I take a look at phenomenology, time and dasein (Heidegger's concept of consciousness) through the example of Christopher Nolan's Dunkirk, the narrative of which is incredibly playful with...

This is the first video in a soon to be series exploring all of the basics of 3D printing. These videos are intended to be watched in order by someone just now getting into 3D printing. In this first video we examine the types of...

Learn how to convert points between rectangular and polar. Rectangular points measure the horizontal and vertical distance away from the origin whereas polar coordinates measure the direct distance and angle in standard position from the...

👉 Learn how to find the midpoint between two points. The midpoint between two points is the point halfway the line joining two given points in the coordinate plane. To find the midpoint between two points we add the x-coordinates of the...

Convert polar coordinates to rectangular coordinates

Cartesian and polar coordinates are introduced and how to switch from one to the other is derived. The concept of angular displacement and arc length are demonstrated. Circumference is shown to be an arc length.

An introduction to Displacement including many different descriptions of displacement. This video also describes the differences between displacement and distance. There are also three different examples illustrating those differences.
