In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but...

Marine mammals are famously large, but why is that? And is there a polar bear-sized sea otter in our future?

In this video Paul Andersen explains how gravitational forces differ from the other three fundamental forces; electromagnetic, strong, and weak. Gravitational forces are always attractive and operate at all scales. Even though...

If you've ever wanted to get up-close and personal with the Moon, you might want to look up this Monday, because the moon will look larger and brighter than it has for decades.

Cats and dogs have it tough: They can't use straws, or tip a cup up to their mouths to drink. Instead, they have to use their tongues and a few different physics tricks to quench their thirst.

Today we’re going to create memory! Using the basic logic gates we discussed in episode 3 we can build a circuit that stores a single bit of information, and then through some clever scaling (and of course many new levels of...

Our need for data storage grows everyday... but by how much?

How can the tiny moon eclipse the sight of the gargantuan sun? By sheer coincidence, the disc of the sun is 400x larger than the disc of the moon, but the sun is 390x farther from Earth -- which means that when they align just right, the...

Hank and physiologist Jon Harrison discuss the question of insect size and major theories that attempt to explain why there is a limit to how large insects can get with current conditions on Earth.

When it comes to our blood-producing stem cells, biologists have learned that bigger is not better. And a study has taken a look at the accomplishments and obstacles of an in-progress attempt to restore a large belt of degraded land...
