Why can you stand on a glacier but not the ocean? The answer seems simple enough: Liquids flow. Solids don’t. The atoms in liquids can slosh around. In solids, they fall lockstep into a crystal ...

In middle and high school, most people learn about the three states of matter we interact with in our everyday lives: solid, liquid and gas. Some students may have even been introduced to the idea of ...

Before scientists discovered the new state of matter last week, we were basically all used to just three states of matter. After all, during our daily lives we encounter some variety of solids, ...

Plasma happens when gas gets heated to a very high temperature and the atoms lose their electrons. Find out more about this state of matter. Science Trek is available to stream on pbs.org and the free ...

Glass and other strange materials have long confounded textbook definitions of what it means to be solid. Now, two groups of physicists propose a new solution to the riddle. The answer seems simple ...

The state of matter is a deceptively simple concept. It turns out that any material, no matter what it is made of, can exist in one of three forms: solid, liquid or gas. These are categories of stuff ...
