Journey to the Center of a Neutron Star
There are a lot of incredible things in space, but neutron stars are some of the most mind-blowing. From liquid plasma oceans on the surface to a possible neutron superfluid in the core — as you go deeper into a neutron star, the physics...

TED-ED: What is metallic glass? - Ashwini Bharathula
Steel and plastic are essential to much of our infrastructure and technology. Steel is strong and hard, but difficult to shape intricately. Plastic can take on just about any form, but it's weak and soft. Wouldn't it be nice if there...

TED-ED: The genius of Marie Curie - Shohini Ghose
Marie Sk_odowska Curie's revolutionary research laid the groundwork for our understanding of physics and chemistry, blazing trails in oncology, technology, medicine, and nuclear physics, to name a few. But what did she actually do?...

TED-Ed: How to squeeze electricity out of crystals - Ashwini Bharathula
It might sound like science fiction, but if you press on a crystal of sugar, it will actually generate its own electricity. This simple crystal can act like a tiny power source because sugar happens to be piezoelectric. Ashwini...

Redox Reactions: Crash Course Chemistry
All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons jump from...

Why You Can't Bake a Mason Jar
Regular old glass like the kind that makes up a mason jar can shatter and explode if put in the oven. But we do have types of glass that you can bake your pie or brownies in and it's all thanks to some neat chemical tricks.

Why Carbon Dating Might Be in Danger
Carbon dating transformed fields like archeology and paleontology, but its use might be in danger.

The Nucleus: Crash Course Chemistry
Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of...

Do You Need a Copper Pot?
Some chefs swear by copper pots and pans, but they are much more expensive than other materials. Are they worth it? Well, it all comes down to electrons!

Bond Length and Bond Energy
In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...

Who decides how long a second is? | John Kitching
In 1967, researchers gathered to answer a long-running scientific question: just how long is a second? It might seem obvious at first. A second is the tick of a clock, the swing of a pendulum, the time it takes to count to one. But how...

The Real Philosopher's Stone: Turning Lead into Gold
With scientists’ efforts and their creativity, we finally found “the real philosopher’s stone.” That's right, we can now turn lead into gold... a little bit.

Polar & Non-Polar Molecules: Crash Course Chemistry
Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or...

TED-ED: The 2,400-year search for the atom - Theresa Doud
How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

Bonding Models and Lewis Structures: Crash Course Chemistry
Models are great, except they're also usually inaccurate. In this episode of Crash Course Chemistry, Hank discusses why we need models in the world and how we can learn from them... even when they're almost completely wrong. Plus, Lewis...

Passing Gases: Effusion, Diffusion and the Velocity of a Gas - Crash Course Chemistry
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 appears. In...

Quantum Tunneling Takes a Surprisingly Long Time
Quantum tunneling happens when a particle seemingly teleports across a barrier. But despite how instantaneous this event sounds, recent research suggests that it doesn’t happen nearly as fast as you might think.
