awkwardsituationist:

though usually hidden to the human eye, naturally occurring marine biofluorescence can be seen under certain wavelengths of light (like ultraviolet), which causes the cells of the organisms seen here to absorb the light — and some of the photon’s energy — and then emit back a now less energetic light that consequently has a longer wavelength and thus a different colour.

A water droplet can rebound completely without spreading from a superhydrophobic surface. The photo above is a long exposure image showing the trajectory of such a droplet as it bounces. In the initial bounces, the droplet leaves the surface fully, following a parabolic path with each rebound. The droplet’s kinetic energy is sapped with each rebound by surface deformation and vibration, making each bounce smaller than the last. Viscosity damps the drop’s vibrations, and the droplet eventually comes to rest after twenty or so rebounds. (Image credit: D. Richard and D. Quere)

Amazing electron microscope imagery! (some of these have been artificially colored)
