Glenn Seaborg: Shaking Up the Periodic Table
Hank synopsizes the life and work of Glenn Seaborg, pioneer of synthetic elements, member of the Manhattan Project, and the architect of the last great shake-up of the periodic table.

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...

Conservation of Charge in Reactions
In this video Paul Andersen explains how the charge is conserved in nuclear reactions. When elementary particles are created or destroyed in a reaction the net change in charge will remain constant. Alpha, beta -, and beta+ decay are...

This Tank of Water Could Change Physics Forever
No one has ever conclusively seen a proton turn into other, lighter particles, but fifty million liters of water in Japan might change that and our ideas about subatomic particles forever.

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...

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: How polarity makes water behave strangely - Christina Kleinberg
Water is both essential and unique. Many of its particular qualities stem from the fact that it consists of two hydrogen atoms and one oxygen, therefore creating an unequal sharing of electrons. From fish in frozen lakes to ice floating...

TED-ED: Could we create dark matter? - Rolf Landua
Eighty-five percent of the matter in our universe is dark matter. We don't know what dark matter is made of, and we've yet to directly observe it, but scientists theorize that we may actually be able to create it in the Large Hadron...

Strong Interaction: The Four Fundamental Forces of Physics #1b
Hank continues his primer on the strongest of the four fundamental interactions of physics, the strong interaction. Today he talks about the nuclear force and a force carrier called a pion.

TED-Ed: The science of static electricity - Anuradha Bhagwat
We've all had the experience: you're walking across a soft carpet, you reach for the doorknob and - ZAP. But what causes this trademark jolt of static electricity? Anuradha Bhagwat sheds light on the phenomenon by examining the nature of...

Water: A Polar Molecule
In this video Paul Andersen explains how the polarity of water makes life on the planet possible. Oxygen is highly electronegative and pulls the electrons closely creating a partial negative charge. The polarity of water (and the...

Coulomb's Law
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 of...

Strong Interaction: The Four Fundamental Forces of Physics #1a
Part one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong interaction - which on the small scale holds quarks together to form protons, neutrons and other hadron particles.

Elementary Charge
In this video Paul Andersen explains how electric charge is quantized and how the smallest unit of charge is 1.6x10^-19 C, or the elementary charge. Robert Millikan discovered the elementary charge using the oil drop experiment....

Strong Nuclear Force
In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons...

Acid-Base Reactions in Solution: Crash Course Chemistry
Last week, Hank talked about how stuff mixes together in solutions. Today, and for the next few weeks, he will talk about the actual reactions happening in those solutions - atoms reorganizing themselves to create whole new substances in...

Radiation and Radioactive Decay
Mr. Andersen explains why radiation occurs and describes the major types of radiation. He also shows how alpha, beta, and gamma radiation affect the nucleus of a radioactive atom. Nuclear equations are also discussed.
