Why are we using tech from 100 years ago to deliver the world's electricity? Materials scientist Jason Huang shows how we could massively upgrade the global power grid by replacing the wires in existing transmission lines with new,...

If you're flying on a plane in a thunderstorm, you should be more worried about the wind than the lightning.

Roller coasters give people the opportunity to experience physics in dramatic ways. In this episode of SciShow, we break down how physics work on roller coasters to give you the ride of your life!

3 Surprising Things Matter Does Under Extreme Pressure

If you're flying on a plane in a thunderstorm, you should be more worried about the wind than the lightning.

The United States' Constitution is not a very detailed document. It lays out the basic structure of government, and the details are filled in with legislation, and clarified and reinforced by court decisions. One of the most...

First of all, DON'T DO IT! But if you WERE to stick your tongue to a cold flagpole, why would it stick?

In this video Paul Andersen explains how electric permittivity of a material resists the formation of electric fields. Capacitors store energy be preventing the formation of electric fields in dielectric material. The electric...

In this video Paul Andersen explains how metallic bonding structure creates the different properties of metals. The electron sea model explains how the positive nuclei are locked into a negative sea of delocalized electrons. This...

Learn the key principles of electrostatic equilibrium in this clear and engaging physics lesson from Flipping Physics. Discover why the electric field inside a conductor is zero, how excess charges distribute themselves on the surface,...

Electrical conductivity varies from metals to insulators. Solids can be divided into three categories: conductors, insulators, and semiconductors. Conductors are solids through which electricity can flow to a large extent, classified as...

Beautiful Bonds: The World of Covalent and Metallic Solids

Covalent solids, also known as network solids, are materials with atoms bonded together in a continuous network by covalent bonds, resulting in large, rigid structures....

Molecular Matters: Polar and Non-Polar Solids

Polar molecular solids are crystalline solids with a permanent dipole moment due to differences in electronegativity between atoms. These solids have strong dipole-dipole...

Exploring Crystalline Ionic Solids.

Crystalline solids have a regular internal arrangement of particles, a long range order, and sharp melting points. They are hard and rigid, with a characteristic heat of fusion. They are...

Band Theory Dissection: Conduction in Various Substances

The band theory of solids is a fundamental concept in solid-state physics that explains the conduction of electricity in substances based on the arrangement of energy levels...

Great lengths are taken by energy companies to keep our electricity supply on. To spot any potential power cuts, they use sophisticated equipment, and take to the skies. Physics - Electricity And Circuits - Learning Points. Networks of...

Metals can be strong and hard, or they can be flexible. It's the special behaviour of ions that give metals their different properties. Chemistry - Atoms And Bonding - Learning Points. Metal atoms bond together and create giant lattice...

We use a metal box holding rods of different materials to test their ability to conduct heat. The box is filled with boiling water and a paperclip is attached to the end of each rod using petroleum jelly. As the heat moves through the...
