George Armitage Miller was an American psychologist who was one of the fathers of modern cognitive psychology, and helped to establish psycholinguistics as an independent field of research in psychology. His early studies were in speech production and perception. Later he worked on human memory. In his most famous paper, The Magical Number Seven, Plus or Minus Two: Some Limits on our Capacity for Processing Information (1956) he described some limits on the human capacity to process information. Since 1985, Miller oversaw development of WordNet, a lexical database for the English language, funded in part by government agencies interested in machine translation. In 1991 he was awarded the National Medal of Science.[Ref: The Psychological Review (1956), 63, 81-97.]

Danish botanist and geneticist whose experiments in plant heredity offered strong support to the mutation theory of the Dutch botanist Hugo de Vries (that changes in heredity come about through sudden, discrete changes of the heredity units in germ cells). Many geneticists thought Johannsen's ideas dealt a severe blow to Charles Darwin's theory that new species were produced by the slow process of natural selection. In 1909, Johannsen proposed that each portion of a chromosome that controls a phenotype be called a "gene" (Greek: "to give birth to").

American inventor of explosives, much used in WW I. In his early career, a printing business at Pittsfield, Mass. (1883) he invented a method of color printing in newspapers. He turned to improving explosives and made the first smokeless powder in the U.S. It was adopted by the U.S. Army. In 1901, he invented maximite, a high explosive bursting powder 50% more powerful than dynamite. When used in torpedoes, maximite resisted both the shock of firing and the greater shock of piercing armour plate without exploding until it was then set off by a delayed-action detonating fuse, another Maxim invention. Later, he perfected a new smokeless powder, called stabillite because of its high stability, and motorite, a self-combustive substance to propel torpedoes. more

iguanadon
British physician, geologist, and paleontologist, who discovered 4 of the 5 genera of dinosaurs known during his time. As the son of a shoemaker, to a becoming physician, he began a hobby that became all-consuming. An early identification was of the fossil teeth he found while walking with his wife in 1822. When he saw the connection with teeth of the present lizard, the iguana, in 1825, he named the animal the iguanodon (“iguana tooth”). Subsequently, he made additional finds of fossil bones of other large animals which he described accurately: the hylaeosaurus, pelorosaurus, and regnosaurus. His contemporary, paleontologist Sir Richard Owen, coined the word dinosaur (“terrible lizards”). Mantell's books include Medals of Creation (1844).

Ernst Walter Mayr was a German-American biologist who merged genetics with evolution to explain how new species evolve. As a youth, he enjoyed bird watching, and by age 10, could recognize all the local bird species by sight or call. By age 21, he had earned a Ph.D. in ornithology (Jun 1926). In 1928-30, aged in his 20s, Mayr headed three scientific expeditions to New Guinea and the Solomon Islands to study the effects of geographic distribution among various animal species. He became a leader developing the modern synthetic theory of evolution (in which ideas of gene mutation and their molecular evolution over time are merged with the effects of reproductive isolation and natural selection). In 1940, Mayr presented a definition of species to identify similar but different species.«

Félix-Édouard-Justin-Émile Borel was a French mathematician who (with René Baire and Henri Lebesgue), was among the pioneers of measure theory and its application to probability theory. In one of his books on probability, he proposed the thought experiment that a monkey hitting keys at random on a typewriter keyboard will - with absolute certainty - eventually type every book in France's Bibliothèque nationale de France (National Library). This is now popularly known as the infinite monkey theorem. He was first to develop (1899) a systematic theory for a divergent series. He also published (1921-27) a number of research papers on game theory and became the first to define games of strategy.

English physicist and electrical engineer who predicted the existence of the ionosphere. In 1870, he became a telegrapher, but increasing deafness forced him to retire in 1874. He then devoted himself to investigations of electricity. In 1902, Heaviside and Arthur Kennelly predicted an ionised layer in the upper atmosphere that would reflect radio waves—useful for long distance communication. Radio signals can travel to distant parts of the earth by bouncing off the underside of this layer, as short-wave radio hams well know. The existence of the Heaviside layer (ionosphere) was demonstrated in the 1920s, when radio pulses were transmitted vertically upward and the pulses returning from the reflecting layer were received.«

Of these, his Birds of Australia was particularly significant (1840-69) as the first comprehensive record of the continent's birds and mammals. With its plates of the birds were descriptions, notes on their distribution and adaptation to the environment. He assisted Charles Darwin with identification of the specimens collected during the voyage of the Beagle. By informing Darwin that the finches belonging to separate species, he provided essential information giving Darwin insight leading to his later development of the theory of evolution.«[Image right: Plate from Vol III of Birds of Australia showing a male and two young Dusky Robins, Petroica Fesca.]

By 1769, he was using the word “technology,” which he coined for the science of trades. From an educational trip (1765-66), by inspecting factories, mines and foundries he had a good background in the manufacture of natural products and the mining of metals. He published the first advanced textbook (1777) with a systematic approach describing the processing of raw materials in different trades. With his influence, secondary schools introduced a technology curriculum. By researching primary sources, he was also a reliable historian of inventions.«

Italian mathematician, poet, and brother of the mathematician Giovanni Ceva. At the age of fifteen he entered the Society of Jesus. His education was entirely within the Jesuit Order and he obtained a degree in theology. His first scientific work, De natura gravium (1669), dealt with physical subjects, such as gravity and free fall, in a philosophical way. Tommaso Ceva's mathematical work is summed up in Opuscula Mathematica (1699) which examines geometry (geometric-harmonic means, the cycloid, and conic sections), gravity and arithmetic. He also designed an instrument to divide a right angle into a given number of equal parts. He gave the greater part of his time to writing Latin prose. His poem Jesus Puer was translated into many languages.«

German inventor and printer who invented movable type. Johann Gensfeisch zur Laden zum Gutenberg, was a German craftsman and inventor of movable type used together with a new type-metal alloy, a new press, and an oil based printing ink. In combination, this was a new method of printing never used before. Gutenberg prepared his type by casting any quantity of precise copies of a letter stamped into the mold. His screw press pressed paper lying on an inked type forme in a manner similar to presses used in winemaking.[Birth year circa 1394-99.] more

In 1984, a Long Beach, Calif., hospital announced the birth of the world's first baby conceived by embryo transplant.
In 1966, three days after its takeoff, the unmanned Soviet Luna 9 spacecraft landed safely on the moon in the Ocean of Storms. It was the first ever soft landing on another celestial body, and opened the way for manned trips to the moon, by removing doubts lest the surface was an unsafe dusty quicksand. On striking the surface, the Soviet probe ejected a 250-lb capsule which then rolled upright and unfolded four spring actuated petals to steady itself. A TV camera with a revolving mirror system enabled Luna 9 to take pictures, including panoramic views of the lunar landscape and closer views of nearby rocks, which were transmitted back to earth until 6 Feb when the batteries ran out and contact with the spacecraft was lost.
In 1966, the U.S. launched its first operational weather satellite, ESSA-1 to provide cloud-cover photography to the U.S. National Meteorological Center for preparation of operational weather analyses and forecasts. The spacecraft was an 18-sided polygon, 42-in. diameter, 22-in. high and weight 305-lb. It was made of aluminum alloy and stainless steel, then covered with 9100 solar cells. The solar cells served to charge the 63 batteries. Its two cameras were mounted 180 degrees opposite each other along the cylindrical side of the craft. A camera could be pointed at some point on Earth every time the satellite rotated along its axis. ESSA-1 was able to view the weather of each area of the globe, photographing a given area at the exact same local time each day.
In 1958, Rachael Carson wrote to E.B. White, editor of The New Yorker magazine, to urge him to write a book. The environmental content she had in mind became her famous book, The Silent Spring. However, because White replied that although he felt unable to do it himself, he encouraged her to write it herself. So she did.
In 1925, a report of the first “missing link” fossil, found by Raymond Dart, was published in a newspaper. The Star of Johannesburg, South Africa announced the find, instead of the professional journal Nature, when the editors of the journal changed their mind. In 1924, Dart found the skull that made him famous. Mr. Dart with his students made the find in the Taung limestone works in the Harts Valley of Bechuanaland. When an endocranial cast was found, at first it seemed to be just another primate skull. Then, Dart noticed how amazingly close to human it looked. Dart had discovered the Taung child, who was only three years old at the time of death. He named it Australopithecus africanus. “Australis” meaning south and “pithecus” meaning ape.
In 1891, the city-wide electrical lighting of London streets was marked by a ceremony where the Mayor laid the foundation stone of the principal junction box. This committment came after a dozen years of experiments. Contracts had been awarded to the Brush Electrical Engineering Company and the Laing, Wharton and Down Construction Syndicate for different sections of the city. Each provided their own generating station. The junction box allowed each company to provide back-up power to the other in case either lost production due to any serious accident at a generating station. Every street, lane, court and alley was to be lighted with a total of 400 arc lamps with 2,000 nominal candle power and 1,000 incandescent lamps of varying candle power. Illumination was hoped to be twenty times more than that provided by gas in the past. The cost was expected to be about £20,000 per year.«
In 1880, African-American inventor, Joseph W. Waller of Baltimore, Maryland, was issued a U.S. patent for a “Shoemaker’s Cabinet or Bench” (No. 224,253). The design combined a cabinet and a calf-skin seat. The cabinet was designed with compartments and divisions for boxes, jars and bottles; and pockets for holding various tools. It was also provided with a lamp for heating purposes and a groove for stones for sharpening tools. The seat and its back were hinged to make the cabinet lid, and the seat legs were detachable, so the entire assembly could be shipped as a compact box.

In 1879, the first practically usable incandescent filament electric light bulb was demonstrated to an audience of 700 by its inventor Joseph Wilson Swan at the Literary and Philosophical Society of Newcastle upon Tyne. Following his successful demonstration, Swan established the world's first electric light bulb factory at Benwell in the western subburbs of Newcastle. Later, Swan's bulbs were used to light up Mosley Street in the Newcastle city centre, the first street in the world to be lit by electric light. By 1881, Swan had introduced his bulbs in London where 1,200 of them were used in the lighting the Savoy Theatre in front of an astonished audience.
In 1862, as a boy almost 15 yrs old, Thomas Edison (1847-1931), became the first publisher of a newspaper produced and sold on a moving train. He had set up a small press in the baggage car of the Grand Trunk Railroad train from Port Huron to Detroit, Mich. Already obsessed with telegraphy, he worked out the logistics of getting advance news. His weekly Grand Trunk Herald, a single sheet measuring 7-in. x 8-in., included local news and advertisements for his father's store. He had been selling candy and newspapers on commission on that train run since age 12. Now, promoting his own newspaper he earned more. Edison became renowned as a pioneering boy journalist. At its peak, he sold about 200 copies a day to train riders.
