Sergei Nikolaievich Winogradsky  (1 September 1856 – 25 February 1953) was a Ukrainian-Russian microbiologist, ecologist and soil scientist who pioneered the cycle of life concept.  Winogradsky discovered the first known form of lithotrophy during his research with Beggiatoa in 1887. He reported that Beggiatoa oxidized hydrogen sulfide (H2S) as an energy source and formed intracellular sulfur droplets. This research provided the first example of lithotrophy, but not autotrophy.

On April 6, 1802, Norwegian mathematician Niels Henrik Abel passed away. Abel is well known in mathematics for proving the impossibility of solving the quintic equation by radicals. In parallel to Évariste Galois - who also died young - , he laid the foundations of group theory.

Paul Gottlieb Nipkow from Germany first patented the idea of TV system in 1884 when he was a 23 year old university student. Although he never built a working TV model, his spinning disk model laid the groundwork for the first working model created in 1927 by Alan Archibald Campbell-Swinton.

Jean Bernard Léon Foucault (18 September 1819 – 11 February 1868) was a French physicist best known for the invention of the Foucault pendulum, a device demonstrating the effect of the Earth's rotation. He also made an early measurement of the speed of light, discovered eddy currents, and although he did not invent it, is credited with naming the gyroscope. Wikipedia

A Manhattan Project participant, this Polish Jewish mathematician is the latter half of the Teller-Ulam thermonuclear weapon design.  Besides his work in nuclear physics, Stanislaw Ulam also developed the Monte Carlo method of simulation. This method involves running hundreds of simulations to estimate an event's probability. This strategy is consistently & pervasively used in modeling today.

On March 31, 1890, British physicist and X-ray crystallographer William Lawrence Bragg was born. He discovered the Bragg law of X-ray diffraction, which is basic for the determination of crystal structure and was joint winner (with his father, Sir William Bragg) of the Nobel Prize for Physics in 1915.
