In case you missed this simple demonstration i shared a month ago: A rotating ball casts a shadow that perfectly matches a mass on a spring, revealing how circular motion and simple harmonic motion are linked. A visual proof of sine-wave physics in action.

I did some checking up on the values in meme that was making the rounds on social media. Unfortunately about every value they share is wrong! Watch the video to see how bad math leads to massive misinformation.

Here is the follow up video to last week's. How to do a change of basis, and how to make sense of it, from a simple context.

A cool introduction to what change of basis really means (converting between units but in a multi-dimensional space) and some really cool applications to show why it is important.

Did you know that when you watch a 3D animation you are actually watching a shadow of a 4D figure cast down to 3D that is then projected on your 2D screen? Below is a link to a video that explains why animations are actually done in 4D.

We do the math behind this amazing story where water from an 8 in (20 cm) pipe blows an 8 ton block of concrete out of the ground and back 27 feet (8 meters).

A cool problem I used on my Linear Algebra class to show that their preferences on the first day of class help to predict their midterm scores.

A cool video on the power of good boardwork in math class.

An analysis of me and my rollaboard, and why it causes me (and others) headaches when I travel.

@mark_mkram Mark, I am so sorry. I was facing some medical issues when you sent this. I did not mean to be unresponsive. Email me at maththeworld AT mathed D0T byu D0T edu

What is the cost of the American Dream? https://t.co/4meSYQS3Ny says 4.4 million. We tried a more accurate analysis and got MUCH less. Our analysis is not perfect, what would you change? What did we miss?

My son swallowed a nail! We figure out how long it is based off of an x-ray image.

This is the funniest math story that I have with my kids. I actually got them to do math to see how long it would take them to burn their math book at the end of the school year! (my 10 year old didn't like math then).

We order some astronomically large numbers, and show how scientists actually estimate things like the number of stars in the universe, and number of words ever uttered in the history of mankind.

Here is a video that can help you really understand the idea of a mean, and why there are so many different kinds of means in math/stats.
