Joseph Leonard Goldstein is an American molecular geneticist who, along with Michael S. Brown, was awarded the 1985 Nobel Prize for Physiology or Medicine for their elucidation of a key link in the metabolism of cholesterol in the human body. They compared cells of normal persons with those of persons having familial hypercholesterolemia, (who inherit a tendency to abnormally high blood cholesterol levels and circulatory ailments). They traced a genetic defect that resulted in their being deficient in cell receptors for LDL (low-density lipoproteins - the primary cholesterol carrying particles). These cell receptors draw the LDL particles into the cells as a prelude to breaking them down, and thus remove them from the bloodstream.

Austrian-American physicist who devised an experiment to show that neutrinos always rotate in one direction (only counterclockwise). His method was simple, elegant, and used an apparatus small enough to fit on a benchtop, rather than employing a huge accelerator. He also discovered that the nucleus of the deuterium atom consists of a proton and a neutron. In the decade (1961-73) that he headed the Brookhaven National Laboratory in New York, he oversaw the experiments there which led to three Nobel Prizes. He died at age 100.«

American pharmacologist was a medical research pioneer who was awarded a share of the Nobel Prize for Physiology or Medicine in 1988 (with Gertrude B. Elion and Sir James W. Black) for development of drugs for several major diseases. In the 1950s, he and colleague Elion developed thioguanine and 6-mercaptopurine, that treated leukemia, and in 1957, azathioprine, used in treating severe rheumatoid arthritis and other autoimmune disorders. Their drug allopurinol was effective treatment for gout. Other important drugs they developed include pyrimethamine, an antimalarial agent; trimethoprim, a treatment for urinary and respiratory tract infections; and acyclovir, the first effective treatment for viral herpes.«

Hugh Longbourne Callendar was an English physicist who was famous for work in calorimetry, thermometry and especially, the thermodynamic properties of steam. He published the first steam tables (1915). In 1886, he invented the platinum resistance thermometer using the electrical resistivity of platinum, enabling the precise measurement of temperatures. He also invented the electrical continuous-flow calorimeter, the compensated air thermometer (1891), a radio balance (1910) and a rolling-chart thermometer (1897) that enabled long-duration collection of climatic temperature data. His son, Guy S. Callendar linked climatic change with increases in carbon dioxide (CO2) resulting from mankind's burning of carbon fuels (1938), known as the Callendar effect, part of the greenhouse effect.«

French chemist who developed improved spectroscopic methods which had recently been developed by Kirchhoff. In 1859, he set out to scan minerals for unknown spectral lines. Fifteen years of persistence paid off when he discovered the elements gallium (1875), samarium (1880), and dysprosium (1886). He ranks with Robert Bunsen, Gustav Kirchhoff and William Crookes as one of the founders of the science of spectroscopy. Guided by the general arrangement of spectral lines for elements in the same family, he believed the element he called gallium (in honour of France) was the eka-aluminium predicted by Mendeleev between aluminium and indium. Since it is liquid between about 30 - 1700 deg C, a gallium in quartz thermometer can measure high temperatures.

Norwegian ethnologist and adventurer who organized and led the famous Kon-Tiki (28 Apr 1947) and Ra (1969-70) transoceanic scientific expeditions. Both expeditions were intended to prove the possibility of ancient transoceanic contacts between distant civilizations and cultures. The Kon Tiki voyage from Peru to Polynesia was a 101-day, 4,300-mile drifting voyage on the 40-sq.ft. raft, a replica of pre-Inca vessels. He wished to show that Polynesia's first settlers could have come from South America. Few scholars at the time, and almost none today, endorsed the idea. They discount the Heyerdahl hypothesis largely on linguistic, genetic and cultural grounds, all of which point to the settlers having come from the west, not the east.

John Ambrose Fleming was an English electrical engineer who invented, and coined the name for, the diode—first thermonic valve (tube). It was a vacuum tube with two electrodes in which the electrons flowed from filament to anode only. Thus, it acted as a rectifier in a circuit, restricting current to flow in only one direction (patented 1904). For an alternating current, only the positive halves of the waves were passed, rectifying from a.c. to d.c. It was used in circuits for the growing telecommunications industry, because it stripped the intermittent Morse code signal from its radio carrier wave. His name is remembered in the Fleming “Left Hand Rule” mnemonic for relating the directions of motion, current and magnetic field for a motor.«

Édouard Albert Roche was a French mathematical astronomer who studied the internal structure of celestial bodies and was the first to propose a model of the Earth with a solid core. He determined (1850) the Roche Limit for a satellite to have a stable orbit around a planet of equal density. The smaller body could not lie within 2.44 radii of the larger body without breaking apart from effect of the gravitational force between them. He later made a rigorous mathematical analysis of Pierre Laplace's nebular hypothesis and showed (1873) the instability of a rapidly rotating lens-shaped body.«

Prominent English physician, poet , philosopher, botanist, naturalist and the grandfather of naturalist Charles Darwin and the biologist Francis Galton. Erasmus Darwin was one of the leading intellectuals of 18th century England. As a naturalist, he formulated one of the first formal theories on evolution in Zoonomia, or, The Laws of Organic Life (1794-1796). Although he did not come up with natural selection, he did discuss ideas that his grandson elaborated on sixty years later, such as how life evolved from a single common ancestor, forming "one living filament". Although some of his ideas on how evolution might occur are quite close to those of Lamarck, Erasmus Darwin also talked about how competition and sexual selection could cause changes in species.

He tasted an unexpectedly sweet trace of a substance that had, he realized, earlier splashed onto the outside of a flask he had handled. It contained L-aspartyl-L-phenylalnine methyl ester. The patent was issued 27 Jan 1970, assigned to his employer, G.D. Searle & Co.

In 1950, the first U.S. jet passenger international trip was a flight from Malton Airport in Toronto, Canada to the International Airport, New York City. The Avro Canada jetliner carried a crew of three, with three passengers, and 15,000 airmail letters (which became the first airmail letters carried in the U.S. by jet plane). The 359 mile flight took one hour, powered by four Rolls-Royce Derwent jet engines.
In 1925, the first U.S. commercial transcontinental radio transmission of a radio facsimile was sent from San Francisco, California to New York City. The photograph showed Marion Davies receiving a make-up box as a gift from Louis B. Mayer of Metro-Goldwyn-Mayer Pictures. The service had been tried out the previous month by the American Telephone and Telegraph Company on 4 Mar 1925.

In 1885, in Japan, a Patent Monopoly Act was proclaimed, which effectively established the Japanese Patent Office at that time. The need for a patent system had become clearly apparent in order to speed up modernization efforts (An earlier patent law passed in 1871 had been short-lived, but was abandoned in the following year because it was poorly understood by the people and the government office experience problems with its operation.) The first patent issued by the new office, on 14 Aug 1885, was to Zuisho Hotta for his formulation of an antifouling paint for ship hulls made of lacquer, powdered iron, red lead, persimmon tannin, and other ingredients. A New Utility Model Law was enacted in the 1905 to complement the patent system.«
In 1846, the first U.S. patent for a telegraph ticker that would print letters of the alphabet was issued to R.E. House of New York City (No. 4,464). It was able to print at the rate of 50 words a minute in Roman letters. It had first been publically exhibited in 1844 at the American Institute Fair in New York City. It was widely used for ten years, until replaced by improved versions.
