11/12/1877, Englishman Eadweard Muybridge, photographer of the American West, used a novel photographic technique to resolve a bet made by the Governor of California, rail magnate Leland Stanford. Stanford believed that all four legs of a racehorse left the ground simultaneously as it galloped. Muybridge proved Stanford right by stringing tripwires across a racecourse and galloping a horse down it, setting off camera shots to obtain a series of still shots. Muybridge then used the novel technique to study dancers and runners in action.

Methods to find this speed include, 1) timing the eclipses of Jupiter�s satellites when at closest and furthest point from Earth, 2) Adjusting the speed of a rotating cog wheel so it turns just one tooth-breadth whilst light travels to a distant mirror and back, and 3) Send a light beam from a source to a rotating mirror and thence to a distant mirror and back, by which time the first mirror has rotated a little, and see how the beam direction has changed.

1801, Ultra-violet radiation was discovered in 1801 when the German physicist Johann Wilhelm Ritter observed that invisible rays just beyond the violet end of the visible spectrum darkened silver chloride-soaked paper more quickly than violet light itself. He called them �oxidizing rays� to emphasize chemical reactivity and to distinguish them from �heat rays�, discovered the previous year at the other end of the visible spectrum.
1800, Sir William Herschel discovered infra-red radiation, by using a sensitive thermometer.
10/10/1797, Thomas Drummond was born. Along with Goldsworth Gurney (born 1798) he invented ;limelight�, an intense beam of light produced by the combustion of lime (calcium oxide) in an alcohol flame with added oxygen, and focussed by a parabolic mirror.
