Squeaks is back from his trip around the world! In this episode, he and Jessi discuss the final stop on his trip: Vatnajökull National Park in Iceland.

Camouflage is nature’s ultimate game of hide-and-seek, and the secret to winning this game is all in the brain. By studying the masters of disguise, we can see how they trick the brain to make themselves invisible — and what this can...

The Limb of the Sun

Now that we have a primer on the aspects of the Big Bang Theory that we know definitely happened, let’s look further into what we don’t yet know, and how the theory could progress in the future. Since there is a discrepancy between...

It may produce creepy images with way too many dogs and eyeballs, but Google’s DeepDream program is actually a valuable window into artificial intelligence.

Moser's circle problem, and its solution.

The Kepler mission has determined that terrestrial planets are extremely common, and may orbit most stars in the Milky Way. But these planets are difficult to directly image because they're dense and small. Our Sun is about ten billion...

What is Pick's Theorem and how can we prove it?

Optical illusions are images that seem to trick our minds into seeing something different from what they actually are. But how do they work? Nathan S. Jacobs walks us through a few common optical illusions and explains what these tricks...

What shape do you most associate with a standard analog clock? Your reflex answer might be a circle, but a more natural answer is actually a torus. Surprised? Then stick around.

Imagine you have four cubes, whose faces are colored red, blue, yellow, and green. Can you stack these cubes so that each color appears exactly once on each of the four sides of the stack?

As your country's top spy, you must infiltrate the headquarters of the evil syndicate, find the secret control panel, and deactivate their death ray. But your reconnaissance team is spotty, and you have only limited information about the...

Vera Rubin graphed the rotation curves of galaxies, helping astronomers better understand the accelerated orbits of stars on the outskirts of galaxies. Her life's work generated some of the first solid evidence for dark matter in the...

Let's look further into what we don't yet know about the Big Bang, and how the theory could progress in the future. Since there is a discrepancy between general relativity and quantum mechanics, we continue to search for a grand unifying...

Why isn't the internet just covered in naked people? Algorithms! However, designing them to distinguish between pornography and people in skin tone clothing or swimsuits is harder than you'd think.

It may produce creepy images with way too many dogs and eyeballs, but Google’s DeepDream program is actually a valuable window into artificial intelligence.

What do you do with an outdated encyclopedia in the information age? With X-Acto knives and an eye for a good remix, artist Brian Dettmer makes beautiful, unexpected sculptures that breathe new life into old books.

Moser's circle problem, and its solution.

The theory of social networks allows us to mathematically model and analyze the relationships between governments, organizations and even the rival factions warring on Game of Thrones.

A very clever proof of Euler's characteristic formula using spanning trees.

Ragnarok: The fabled end of the world, when giants, monsters, and Norse gods battle for the future. The gods were winning until the great serpent Jörmungandr emerged. It swallowed Valhalla and contorted itself across the land. Odin has...

There might be a galaxy made mostly of dark matter orbiting the Milky Way!

How did the periodic table of elements revolutionize our understanding of the world? What scientists contributed to the table we have today? Eric Rosado discusses the key people and discoveries that have molded our understanding of...
