If we ever want to simulate a universe, we should probably learn to simulate even a single atomic nucleus. But it’s taken some of the most incredible ingenuity of the past half-century to figure out how that out. All so that today I can...

The chemistry behind film photography is pretty fascinating. How do film cameras help us turn light into a physical image?

Diamonds are iconic, but some of them might make others a little green with envy.

JoAnn Kuchera-Morin demos the AlloSphere, a new way to see, hear and interpret scientific data. Dive into the brain, feel electron spin, hear the music of the elements ... and detect previously unseen patterns that could lead to new...

In this video Paul Andersen explains how ionic solids form when cations and anions are attracted. When atoms lose or gain electrons they form ions. The strength of the attraction between ions is based on the amount of charge and the...

In this explosive episode of SciShow Quiz Show, Hank Green and SciShow writer Dave Loos test their knowledge of diamonds, the environment, and the many reasons why humans are very strange creatures.

In this video Paul Andersen explains how ionic solids form a lattice between cations and anions. According the Coulomb's Law the lattice energy increases as the ions carry a larger charge and are smaller. Some of the properties of...

Can you grow a human bone outside the human body? The answer may soon be yes. Nina Tandon explores the possibility by examining how bones naturally grow inside the body, and illuminating how scientists are hoping to replicate that...

In this video Paul Andersen explains how thermal conductivity measures the ability of material to transfer heat from a hot to a cold object. The thermal conductivity of conductors is high because the heat travels through the delocalized...

From corundum to alexandrite, there are rare minerals have multi-colors caused by how they form their structure!<br/>

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...

The Schottky defect and its consequences

Ionic crystals of type A B exhibit a Schottky defect, where an equal number of anions and cations are absent from lattice sites to maintain electrical neutrality. This defect is present...

An amorphous solid is one whose atoms or molecules are not arranged in an ordered crystalline lattice.

What exactly are alloys? What is it about their properties that make them so useful for a huge variety of purposes, from construction to jewellery? Chemistry - Periodic Table - Learning Points. Alloys are metals mixed with other...

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...

In a metal, each metal atom readily gives up its outer shell electrons, resulting in a sea of free electrons flowing throughout a lattice of positively charged metal ions. A Twig Science Glossary Film. Key scientific terms defined in...

In this lesson, you will learn to create 3D roof supports or beams using modeling techniques in Blender and create the structural elements that support the roof. You will learn techniques for modeling the beams, adjusting their...

Princeton University physicist Paul Steinhardt describes how physicists can reveal the underlying atomic structure of materials by scattering other particles off them.

Physicist Paul Steinhardt, Princeton University, describes his sense of excitement when, shortly after he determined the diffraction pattern his theoretical new material would produce in a laboratory, someone showed him an experimental...
