Our planet is full of beautiful places, but it’s also full of wonderfully weird places. We've put together some of our favorite episodes about our planet’s weirdest lakes!

Inside chemistry labs, chemists work with what they call superacids. No one's found a specific use for such a fantastically strong acid yet, but chemists are actively looking for one.

Everything is made of chemicals, including the human body, but there are some especially weird ones

In the early 1800s, Michael Faraday showed us how a changing magnetic field induces an electromotive force, or emf, resulting in an electric current. He also found that electric fields sometimes act like magnetic fields, and developed...

Hank continues our series on the four fundamental forces of physics by describing the weak interaction, which operates at an infinitesimally small scale to cause particle decay.

As we learn more about electricity, we have to talk about fields. Electric fields may seem complicated, but they're really fascinating and a crucial part of physics. In this episode of Crash Course Physics, Shini chats about capacitors,...

During peak thunderstorm season, Lake Maracaibo has an average of 28 lightning strikes per minute hit its surface. But why?

Vinegar may have a powerful smell, but did you know it's actually a weak acid? In the chemical economy, acids actively give away their protons while bases actively collect them -- but some more aggressively than others. George Zaidan and...

Hank reaches the fourth and final of the four fundamental interactions in physics: electromagnetism. In this part, he teaches us about the electrostatic force, which builds up a charge in an object and can travel in the form of an...

In 1908, Dutch physicist Heike Onnes figured out how to turn helium gas to liquified helium for the first time. He cooled Mercury and found that all its electrical resistance went away. Electricity in a superconducting...

Pupil outcome: I can describe how magnets can attract magnetic materials, as well as attract and repel other magnets. Key learning points: - All magnets have a north–seeking pole and a south–seeking pole. - Unlike magnetic poles attract...

Isoelectric focusing (IEF) is a high-resolution protein separation technique that separates proteins based on their isoelectric points (pI) using a pH gradient in an electric field. Proteins migrate to the region where their net charge...

In 1803, John Dalton formulated his renowned theory of atoms. The principal tenets of his theory were as follows: ₷ Atoms were thought to be the smallest, hardest, densest, and indivisible particles of matter. Every element is...

In 1897, J.J. Thomson conducted an experiment that led to the discovery of the electron and revolutionized atomic theory by demonstrating that atoms are composed of smaller subatomic particles. Before this, atoms were considered...

Cathode Rays: Key Properties

• Straight-Line Travel: Cathode rays travel in straight lines, casting sharp sha
dows.
• Negatively Charged: Composed of negatively charged particles, specifically electrons, deflected by...

The Moon's polar regions are a shocking place for humans to be.

Anions, formed by electron gain, contribute to ionic bond formation. Larger anions with higher charges enhance the bond's electrostatic attraction

The charge that an object has due to a lack of electrons.

A build up of static electricity is usually harmless, resulting in only small shocks. But in some cases it can be deadly. Discover the danger static electricity poses for helicopters and their crew. Physics - Electricity And Circuits -...

Dr. Forrester defines the terms: atoms, protons, electrons, and neutrons. She explains that atoms are made up of protons, electrons and neutrons. She also teaches that all electricity comes from the electrically charged particles.

This problem is about determining how charge moves in two conducting spheres when a charged rod is brought near them.

In this video, we explore the theory, use, and parameters with wound care and edema control using high-voltage pulsed current.
