How Long To Fall Through the Earth?

How Einstein (& others) discovered Special Relativity. Pi day (3.14) is Albert Einstein's Birthday! To celebrate, we'll explain 4 of his most groundbreaking papers from 1905, when he was just 26 years old.

What exactly are fractals? A common misconception is that they are shapes which look exactly like themselves when you zoom in. In fact, the definition has something to do with the idea of "fractal dimension".

This video is about the Schwarzschild radius of a black hole, (its "event horizon"), and how much mass and density is required to reach the point of no return where an object like a star, neutron star, red giant, etc...

Earthquakes have always been a terrifying phenomenon, and they've become more deadly as our cities have grown - with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be...

The professional astronomer or astrophysicist is a pretty recent phenomenon. In the past, astronomy was often performed by nobility and extremely enthusiastic amateurs. Although it seems like the scientific exploration of our universe is...

Black Holes should have no entropy, but they in fact hold most of the entropy in the universe. Let's figure this out.

On this Space Time Journal Club we look at how gravitational waves can be used to search for extra dimensions of space!

Physics seems to be telling us that it's possible to simulate the entire universe on a computer smaller than the universe

Why Raindrops Are Mathematically Impossible

This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the...

Because smaller animals have to eat more relative to their bodyweight, Tolkein’s hobbits need to eat a lot - not for comfort, but for survival.

Hank continues our series on the four fundamental forces of physics with a description of gravitation -the interaction by which physical bodies attract with a force proportional to that of their masses, and which is responsible for...

We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first...

In this video Paul Andersen shows conceptual thinking in a mini-lesson on proportional relationships. TERMS Quantities - the amount (or number) of a thing Proportional relationship - relation of one dataset to another dataset Directly -...

In this video Paul Andersen explains how we can use Coulomb's law to predict the structure of atoms. These predictions can be verified through the use of Photoelectron Spectroscopy (PES). Electron's are help around the nucleus because...

In this shorts video we will find an unknown side length. We are given a pair of triangles and told they are similar figures. Using the definition of similar figures, similar figures have corresponding sides that are proportional, we...

In this short math video we will discuss similar triangles & proportionality. We will understand that if two figures are similar that their corresponding sides are proportional. We will identify the corresponding sides and write a...

In this Grade 7 math video, we dive into how to determine if a table represents a proportional relationship between two quantities — a key skill aligned with standard 7.RP.A.2.



Students will analyze four real-world...

A video entitled "Testing Graphing" which shows how to use a graph to test if ratios are proportional.

In this video, Mrs. C explains how to determine whether two variables, x and y, form a proportional relationship using tables and graphs. 🔹 *What You’ll Learn:* ✅ How to plot ordered pairs from a table ✅ How to check if a graph shows a...

In this video, we’re diving into **ratios and proportions* with four thought-provoking questions. 🔢 *Here’s what we’ll cover:* ✅ Finding the value of a ratio: Is 1/10 the correct value for 1/2:1/5? ✅ Checking for proportional...
