Does your toilet water drain differently than in the other hemisphere? Is it because of the Coriolis effect? Hank has some things to clarify about these questions, and more in this edition of I Don't Think It Means What You Think It Means.

Earth has its share of monster storms, but even our most powerful hurricanes are a breeze compared to the great, planet-sized tempests of the gas giants.

We're always learning more about far away galaxies and exoplanets, but we still have some pretty big mysteries hanging out here in the solar system, like why Venus spins the way it does.

Research has found some human brains can pick up on rotations of geomagnetic-strength fields as evidenced by drops in alpha wave power following stimulus.

Hurricanes, cyclones and typhoons are formed due to violent storms that originate over oceans and seas and move towards land, potentially causing extensive damage to both life and property. But there is a very interesting thing related...

In this video, let's create a new view, “SpeechBubbleView”, and pass arguments with the CGFloat function. You will learn to alter the tail size and radius of the bubble and try different values until we find an optimal tail size...

This video explains what congruent shapes are. I.e. shapes that are the same shape and size, but may have different orientation (e.g. could have been rotated or reflected).



This video is suitable for maths courses around...

This video examines the force of gravity and looks at its critical role in the formation of the sun and planets of our solar system.

In this music theory lesson we look at the circle of fifths. It can seem complicated at first, but the circle of fifths can be a really useful tool when learning music theory. It organizes key signatures, and it can tell you what kinds...

Now that we've built the circle, how do we use it? What all can we do with the Circle of Fifths?

👉 Learn how to rotate a figure and different points about a fixed point. Most often that point or rotation will be the original but it is important to understand that it does not always have to be at the origin. When rotating it is also...

👉 Learn how to sketch angles in terms of pi. An angle is the figure formed by two rays sharing the same endpoint. Angle is measured in radians or in degrees. One complete revolution about a point is equivalent to 2pi radians and 360...

n this video, I explain the abdominal reflex. More specifically, we discuss the reflex arc and how to determine whether or not the reflex is present/normal or abnormal.
