Joseph Carl Robnett “Lick” Licklider was an American computer scientist who created the idea of a universal computer network to easily transfer and retrieve information which his successors developed into the internet. In 1959, in his first book, Libraries of the Future, Licklider expanded Vannevar Bush's idea of an automated library system to describe how computers could distribute library resources from a single database to multiple remote users. In 1962, while director of the Information Processing Techniques Office of the U.S. Dept. of Defense Advanced Research Projects Agency (DARPA), he sent a memo to colleagues envisioning a time-sharing network of computers. Subsequently ARPANET was built, which became the model for the Internet. He also was a visionary for human-computer interaction, remembered for his 1960 paper, 'Man-Computer Symbiosis.'«

American electrical engineer who headed the U.S. Office of Scientific Research and Development during WW II to stimulate scientific research. His office contracted with, and coordinated research by, universities and industry. The office funded a wide field of activities, such as antibiotic research, improving explosives, and devising blood substitutes. Before the war, in 1925, at age 35, he developed the differential analyzer, the world’s first analog computer. It was capable of solving differential equations. (This put into productive form, the mechanical concept left incomplete by Charles Babbage, 50 years earlier; and theoretical work by Lord Kelvin). The machine filled a 20×30 ft (6×9 m) room.

Joseph-Louis-François Bertrand was a French mathematician and educator and educator remembered for his elegant applications of differential equations to analytical mechanics, particularly in thermodynamics, and for his work on statistical probability and the theory of curves and surfaces. In 1845 Bertrand conjectured that there is at least one prime between n and (2n-2) for every n>3, as proved five years later by Chebyshev. In 1855 he translated Gauss's work on the theory of errors and the method of least squares into French. He wrote a number of notes on the reduction of data from observations.

French chemist and geologist who began the first industrial production of aluminium. His career started with research of turpentine. By 1849, turning to inorganic chemistry, he synthesized nitrogen pentoxide. Friedrich Woehler had isolated aluminum using costly potassium, as a laboratory curiosity. In 1854, Deville made aluminium, from aluminium chloride and less costly sodium. By 1860, he was producing aluminium at a factory in Javel, Paris, and later in Nanterre. The metal was more expensive than gold until Charles Hall invented the cheap electrolytic process. Deville also studied platinum and other minerals. As a geologist, he visited the coastal sites of Vesuvius and Stromboli. He proposed that volcanic eruptions resulted when sea water entered the fissures of the earth's crust where contact with hot rocks produced the explosive eruptions.« more

French astronomer who predicted by mathematical means the existence of the planet Neptune. He switched from his first subject of chemistry to to teach astronomy at the Ecole Polytechnique in 1837 and worked at the Paris Observatory for most of his life. His main activity was in celestial mechanics. Independently of Adams, Le Verrier calculated the position of Neptune from irregularities in Uranus's orbit. As Camille Flammarion said, he discovered a planet with the tip of his pen, without any instrument other than the strength of his calculations alone. In 1856, the German astronomer Johan G. Galle discovered Neptune after only an hour of searching, within one degree of the position that had been computed by Le Verrier, who had asked him to look for it there. In this way Le Verrier gave the most striking confirmation of the theory of gravitation propounded by Newton. Le Verrier also initiated the meteorological service for France, especially the weather warnings for seaports. Incorrectly, he predicted a planet, Vulcan, or asteroid belt, within the orbit of Mercury to account for an observed discrepancy (1855) in the motion in the perihelion of Mercury.

Scottish bacteriologist who discovered penicillin. In 1928, while working on influenza virus, he observed that mould had developed accidently on a staphylococcus culture plate and that the mould had created a bacteria-free circle around itself. He experimented further and he found that a mould culture prevented growth of staphylococci, even when diluted 800 times. The active substance, which he named penicillin, initiated the highly effective practice of antibiotic therapy for infectious diseases. Fleming shared the Nobel Prize for Physiology or Medicine in 1945 with Ernst Boris Chain and Howard Walter Florey, who both (from 1939) continued Fleming's work.

Canadian-American physicist who in 1918 built the first mass spectrometer (based on the invention of Francis W. Aston) and discovered isotope uranium-235 (1935). The mass spectrometer is an instrument that uses electric and magnetic fields to separate and measure a sample's atoms according to their mass and relative quantity. In 1935, he discovered that naturally occurring uranium, though mostly uranium-238, contained 0.7% U-235 (later used as the primary fuel in atomic bombs and reactors after Niels Bohr predicted it could be used to produce a chain reaction releasing huge amounts of nuclear fission energy). During WW II, Dempster worked with the secret Manhattan Project that developed the world's first nuclear weapons.«

Christen Christensen Raunkaer was a Danish botanist and ecologist remembered for the Raunkiaer's classification he used to categorize vegetation with regard to “life-forms” and study the abundance of plant species in different climates. He recognized that the position of the perennating buds of plants offered greater protection in conditions of cold or drought when they were closer to the ground. His frequency method (cirklingsmetoden) was to register all plants within within 0.1 m², in the form of a square or a circle laid out in several places in the area, with data collected then treated statistically. This was first published in 1905, and expanded in form in 1907. It continues to be used worldwide for vegetation analysis. He was a scientific assistant of the Botanical Garden, Copenhagen (1893-11) and thereafter was a professor of botany at the University of Copenhagen until 1923.«

He wrote these landmark ideas in a paper to be submitted to the French Academy of Sciences through his superior, Adolphe Wurtz. Sadly for Couper, that paper was not forwarded from the lab in a timely fashion, and meanwhile another chemist, August Kekulé had published the same, though independent, idea of tetravalence, depriving Couper of his due fame.

It was reset by Congress in the Energy Policy Act of 2005, signed into law by the president on 8 Aug 2005. Among hundreds of other provisions giving incentives and subsidies concerning energy production and conservation, the Act set the change to DST to begin three weeks earlier, on the second Sunday of March, and end a week later on the first Sunday of November. When it was first introduced in the U.S., On 31 Mar 1918, the U.S. first began daylight saving time (DST) on Easter Sunday, when clocks were set ahead by one hour. The concept was introduced earlier in Great Britain during WWI as a coal-conserving measure.«

In 1960, Pioneer V was launched from Cape Canaveral, Florida, in one of the first in-depth attempts to study the solar system. The spacecraft was carried into space on a Thor-Able three stage rocket. It was a beach ball sized spacecraft equipped with four paddle like solar cells that recharged the on-board batteries that provided electrical power. Pioneer V entered an orbit around the Sun between Earth and Venus. It provided a wealth of new data on interplanetary space including measurements of magnetic fields, cosmic radiation, electrical fields and micrometeorites. It was stabilized by slowly spinning about its axis. The spacecraft transmitted information until 26 Jun 1960 when it was 22.5 million miles (36 million km) from Earth.
In 1919, a wireless telephone call was made by Secretary Josephus Daniels at his Navy Department desk, Washington D.C., to Ensign Faganwater, piloting a seaplane 150 miles away. A newspaper report said this was a record distance for such communication. Development began aided by Bell system experts since Feb 1917, with a successful test in Oct 1917. On 21 Nov 1919, President Wilson used a wireless telephone at the White House to direct maneuvers of a formation of planes nearby. Three years earlier, on 6 May 1916, the Secretary of the Navy had given orders, connected by AT&T Co. ship-to-shore radio telephone, to the captain of the battleship New Hampshire. Alexander Graham Bell had transmitted the first wireless telephone message using light in an experiment with his Photophone on 3 Jun 1880.«[Entry previously shown on this site for 16 Mar 1919, but that was date of a Washington newspaper article.] more
In 1918, the first cases of "Spanish Influenza" in the U.S. were reported. Early in the morning, a young private reported to the Army hospital at Fort Riley, Kansas, complaining of fever, sore throat, and headache. By noon, the hospital had more than 100 cases; in a week, there were 500. During the Spring, 48 soldiers died at Fort Riley. No one knew why until the cause of death was identified as influenza - but unlike any strain ever seen. As the killer virus spread across the country, hospitals overfilled, death carts roamed the streets and helpless city officials dug mass graves. It was the worst epidemic in American history, killing over 600,000 - until it disappeared as mysteriously as it had begun. Worldwide, up to 40 million people died in its wake.

In 1851, James W. Fowle was issued he first U.S. Patent for a direct-action percussion rock-drill (No. 7,972). He had filed a caveat in 1849, about two months after Joseph J. Couch received a patent for the first steam-powered percussion rock-drill. In Couch's design, the drill bar was not fastened to the piston head, but at each stroke was alternately caught, drawn back and thrown against the rock, like a lance. Both employed steam power. At first, Couch and Fowle had collaborated, but Fowle separated to pursue his own design, which is the real precursor of the drills developed in the following decades. To employ the direct action on the drill-bar Fowle had to solve the problem of how to avoid damage to the piston cylinder. He used compressed air to drive his “S” shaped drill.«

In 1811, the Luddite riots began in Nottingham, England. There was poverty and misery, made worse by the new inventions - machinery which could do jobs better and faster than people. In those days of low wages and the ever-present threat of actual starvation should those wages stop for any reason, these innovations must have made the prospect even more gloomy. There were food shortages resulting from the Napoleonic Wars, and high unemployment. A group of laborers attacked a factory, breaking up 63 stocking and lace manufacturing frames, the machines which they feared would replace them.

In 1791, Samuel Mulliken of Philadelphia, Penn. became the first person to receive more than one U.S. patent. The Secretary of State issued him the first patent on a threshing machine for corn and grain, being the seventh in the records of the office. On the same day he was granted three more letters patent: for breaking and swingling hemp; for cutting and polishing marble; and to raise the nap on cloths. Although his threshing machine was too complicated to work efficiently, no other inventors made significant improvements until 1820. The Patent Office records concerning these patents were destroyed in the 1836 fire. Most were not reconstructed, and the full patents are not now available in the Patent Office records.«
In 105, Ts'ai Lun invented paper, made from bamboo, mulberry, and other fibers, along with fish nets and rags. He lived and served as an official at the Chinese Imperial Court at the Han Dynasty in China. He presented samples of paper to Emperor Han Ho Ti. He was promoted by the Emperor for his invention and became wealthy. Later he got involved in palace intrigue, which led to his downfall. Finally he ended his life drinking poison. In China, before Tsai, Lun, books were made of bamboo, which were heavy and clumsy. Some books were made of silks, which were very expensive. In the West at that time, books were made of sheepskin or calfskin.
