If gravity is so attractive, why doesn't the earth just crash into the sun? Or the moon into the earth? The answer: Stable Orbits

As much as we like to talk about vibes, actual vibrations underlie pretty much everything about the universe. From the patterns of galaxies created by the Big Bang to the existence of subatomic particles, here's how the universe runs on...

Hank introduces us to the most beautiful numbers in nature - the Fibonacci sequence.

Throughout history humans have come up with lots of different ways to build shelters for themselves. But sometimes, inspiration for better construction materials comes from nature, in structures you might not expect — like the scales on a

Our Milky Way galaxy is alive and well, producing new stars all the time. But there’s another group of galaxies out there, populated only by venerable red dwarf stars - the young stars are nowhere to be seen. In effect, these galaxies...

There’s a massive black hole next door that appears far too big for its host galaxy! And in another galaxy, TWO supermassive black holes formed, giving us a glimpse at a true rarity in astronomy!

Most galaxies that we know of are spirals, including the Milky Way, but how do they form and keep their shape over billions of years?

There are many fossils that challenge our ability to form even the most basic idea of how a living thing looked, or lived, or functioned. One of the longest-running of these mysteries involved a 270-million-year-old sea creature called...

A curious pattern in polar plots with prime numbers, together with discussion of Dirichlet's theorem

In the 1700s, sailors used sextants to navigate the seas. Centuries later, these old-timey tools saved the day on not one, but two of the Apollo missions!

Humans don't have interconnected teeth for slicing, or a secondary set of jaws to clamp down on prey already in our mouths, however, the rest of our animal kingdom is full of strange and awesome adaptations.

Jessi and Squeaks explore our home galaxy, The Milky Way!

Your body is made of cells -- but how does a single cell know to become part of your nose, instead of your toes? The answer is in your body's instruction book: DNA. Joe Hanson compares DNA to detailed manual for building a person out of...

With so many galaxies in the universe, some are bound to astound us. Here are three of the most extreme galaxies scientists have discovered so far.

Hank introduces us to the most beautiful numbers in nature - the Fibonacci sequence.

This video is about cutting, taping, and rearranging the periodic table into the Left Step form, the Mendeleev's flower form, the cake form, the wide form, the standard form, and so on. A great holiday...

The Milky Way is our neighborhood in the universe. It’s a galaxy and there are many others out there. Galaxies contain gas, dust, and billions of stars or more. They come in four main shapes: elliptical, spiral, peculiar, and irregular....

Now that we have an understanding of the principles of forensic science, we can begin to examine crime scene investigation. CSI involves many steps, but the first three are protecting the crime scene, recognizing evidence, and searching...
