All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck’s law. If, however, the radiating object is smaller than the thermal wavelength, it behaves according to different rules and cannot emit the energy efficiently.
It's not just artistic types that find math a turn-off and try to avoid having to deal with it - scientists do the same.
In the beginning was the equation - and University of Michigan researchers say they've demonstrated mathematically that it's possible to make something out of nothing.
