Students will learn how to categorize matter as either pure substances or mixtures. Students will apply tests, based on physical properties of matter samples, to determine whether a mixture is ...

One of the most important tasks for physics is to describe natural observations using a minimal set of principles. This approach allows researchers to understand phenomena of impressive complexity ...

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, ...

At the end of a lecture on astronomy, describing how the planets orbit the Sun, a little old lady at the back of the room stood up and said: "What you've told us is all rubbish. The world is really a ...

Active matter can have macroscopic properties that defy the usual laws of hydrodynamics. Now these tell-tale properties have been traced down to the non-equilibrium character and handedness of ...
