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...

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...

So far in this series we’ve focused on molecules with tens of atoms in them, but in organic chemistry molecules can get way bigger! Polymers are molecules that contain hundreds, thousands, or even millions of identical subunits. In this...

In this video Paul Andersen compares and contrasts the properties of solids and liquids. Solids have a more organized structure which can either be amorphous or crystalline. In liquids the intermolecular forces are lower and so the...

What makes crystals grow into their signature shapes? Dig into the atomic patterns and unique properties of crystals. -- Many crystals have signature shapes— like the cascade of pointed quartz or a pile of galena cubes. Every...

Is Glass a Liquid?

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

Nobel Laureate in Physics Anthony Leggett (Illinois) describes how we could well explore different models to explain the structure of many glassy materials.

Nobel Laureate Antony Leggett details the logical fallacy of "affirming the consequent", stressing that we must always make sure that another model might explain the phenomenon in question, giving a concrete example to illustrate his point.

Physicist Paul Steinhardt, Princeton University, describes his early experiences that led him on the road towards the discovery of so-called quasicrystals, a new state of matter.

Explore how gemstones get their colors. We learn that gemstones absorb and reflect certain light waves based on their chemical structures, resulting in different colors. Some gemstones are self-colored, while others are colored by...

This video is answering the question of are there different types of solids.
