Photons are massless particles that always move at the speed of light when in vacuum. The photon belongs to the class of boson particles.

Grandfather Cuts Loose the Ponies (also known as the Wild Horse Monument) is a public art sculpture created by David Govedare in 1989–1990 and situated near Vantage, Washington. It consists of 15 life-size steel horses which appear to be galloping across a ridge above the Columbia River. Presented as a gift for the centenary of Washington’s statehood, the sculpture was conceived as a memorial to the wild horses which once roamed the region. According to the Seattle Times, it is one of the most-seen public artworks in Washington state.
