In the microscopic world, as long as there are only two particles, things are relatively simple. When other particles are introduced, however, the situation soon becomes more complicated. Imagine there are two people pushing ...

Liquid water is a very good heat storage medium – anyone with a Thermos bottle knows that. However, as soon as water boils or freezes, its storage capacity drops precipitously. Physicists at the University of Bonn have ...

If you put water on the stove and heat it up, it will at first just get hotter and hotter. You may then conclude that heating water results only in hotter water. But at some point everything changes – the water starts to ...

When a material undergoes a phase transition from a disordered to an ordered state, its properties change and these changes are observed via macroscopic observables such as specific heat capacity measurements.

The swirling field of a magnet—rendered visible by a sprinkling of iron filings—emerges from the microscopic behavior of atoms and their electrons. In permanent magnets, neighboring atoms align and lock into place to ...

Fluid flows can take one of two forms: well-ordered "laminar" or highly disordered "turbulent" motion. Although everyday experience shows that laminar motion in simple shear flows as in pipes or channels gives way to turbulence ...
