My favorite experiments are not necessarily the groundbreaking ones. I love those too, don't get me wrong; but I like the ones that make me take a good hard look at the way in which I picture the physics.
One critical skill in physics is knowing what to leave out. For instance, if I can predict and describe a physical system with classical physics, why add quantum mechanics? But a recent paper highlights that it is always important to bear in mind that every classical picture has a quantum background. You may be able to neglect that background, but should never forget that it is there.
The experiment involves thinking about optical cavities, which are sort of on the border between quantum and classical worlds. Normally, we think about optical cavities in terms of the color, or wavelength of light that an optical cavity will accept. The distance between the mirrors must be commensurate with the wavelength. This can be described by both classical and quantum physics. The amount of light in the cavity, however, is almost always thought of in terms of classical physics.

Hitching a ride to low Earth orbit, LightSail A accomplished a challenging test mission, unfurling its 32 square meter mylar solar sail on June 7. This dramatic image from one of the bread loaf sized spacecraft's fisheye cameras captures the deployed sail glinting in sunlight. Sail out and visible to Earthbound observers before its final orbit, LightSail A reentered the atmosphere last weekend. Its succesful technology demonstration paves the way for the LightSail B spacecraft, scheduled for launch in April 2016. Once considered the stuff of science fiction, sailing through space was suggested 400 years ago by astronomer Johannes Kepler who observed comet tails blown by the solar wind. But modern solar sail designs, like the one tested by LightSail A, rely on the small but continuous pressure from sunlight itself for thrust.The air around us is a chaotic superhighway of molecules whizzing through space and constantly colliding with each
