German physicist who developed the Paul trap, an electromagnetic device that captures ions and holds them long enough for study and precise measurement of their properties. During the 1950s he developed the so-called Paul trap as a means of confining and studying electrons. The device consists of three electrodes - two end caps and an encircling ring. The ring is connected to an oscillating potential. The direction of the electric field alternates; for half the time the electron is pushed from the caps to the ring and for the other half it is pulled from the ring and pushed towards the caps. For his work he shared the 1989 Nobel Prize for Physics with Hans Georg Dehmelt and Norman F. Ramsey.

American inventor and manufacturer of electronic musical instruments, including the first solid-body electric guitar to be mass-produced: the Fender Broadcaster (1948, renamed the Telecaster two years later). He was an electronics enthusiast and radio repairman who got involved with guitar design after guitar-playing customers kept bringing him their external pickups for repair. Before Fender came along, guitarists met their amplification needs by attaching pickups to the surface of their hollow-bodied instruments. The Stratocaster (1954), had a flashier, contoured, double-cutaway body, with three (as opposed to two) single-coil pickups and a revolutionary string-bending (tremolo) unit. It became a much favored model of rock guitarists.

Arne Wilhelm Kaurin Tiselius was a Swedish biochemist who won the Nobel Prize for Chemistry in 1948 for his work on electrophoresis and other new methods of separating and detecting colloids and serum proteins. In electrophoresis - a method of separating chemically similar charged colloids - an electrical field is applied to the sample, and particles with different sizes migrate at different rates to the pole of opposite charge, enabling them to be detected and identified. Using the technique on blood serum Tiselius confirmed the existence of four different groups of proteins - albumins and alpha, beta, and gamma globulins. Tiselius also conducted work on chromatography (from 1940) and partition and gel filtration (from the late 1950s).

English builder who invented Daylight Saving Time. He claimed he had the idea while taking an early summer morning ride in Petts Wood near to his home in Chislehurst, London. He observed that many blinds were still down, although there was already good daylight, yet many made no use of it. He used his wealth as a prominent home builder to campaign for a scheme of adjusting clocks with the season and published a pamphlet in 1907. His original idea was to make four weekly changes of 20-mins each, for a total of 80-mins. The first Daylight Saving Bill, proposing a single one hour at the change of season failed in 1908. After his death, the idea was adopted during WW I for wartime fuel savings. A memorial was erected in Petts Wood.[Image right: Sundial on the Willett memorial tin Petts Wood.]

German explorer, natural scientist and botanist who acted as a natural historian on the imperial scientific expedition led by Friedrich Müller in eastern Siberia (1733-43). From barometric pressure readings, he was first to determine that the shores of the Caspian lay below sea level. In 1735, at the town of Yeniseysk, he recorded a record low temperature. He also detected the permafrost in eastern Siberia, which, a little way below the surface of the ground remained frozen year round. Gmelin spent the period 1747-69 preparing a book recording his finds there. In Flora sibirica sive historia plantorum Sibiriae, he detailed 1,178 species and provided 294 illustrations. His original degree was in medicine (1727), but his fields of study included chemistry, natural resources, geology, zoology, ethnography and geography. He was Leopold Gmelin's great uncle.«

Sidney Walter Fox was an American biochemist who was interested in the biological origin of life, rather than tracing a strictly biochemical path. He gave the name proteinoid to the protein-like polymer that results from a mixture of amino acids subjected to such considerable heating as would be present during the volcanic primordial earth. Fox observed that when proteinoids or "thermal proteins," are placed in water, they self-organize into microspheres or protocells, possible precursors of the contemporary living cell. Fox argued that RNA or DNA need not date back to the origin of life, and he showed that proteinoid microspheres exhibit growth, metabolism, reproduction (by budding), and responsiveness to stimuli - all properties of life - though without a genetic system.

German physicist noted especially for his work with Otto Stern on the deflections of atoms in a nonhomogeneous magnetic field. The Stern-Gerlach experiment is a demonstration of the restricted spatial orientation of atomic and subatomic particles with magnetic polarity, performed in the early 1920s by the German physicists Otto Stern and Walther Gerlach. In the experiment, a beam of neutral silver atoms was directed through a set of aligned slits, then through a nonuniform (nonhomogeneous) magnetic field.

Felix Andries Vening Meinesz was a Dutch geophysicist and geodesist who was known for his measurements of gravity at sea for which he devised the Vening Meinesz pendulum apparatus with comparable accuracy as on land. Starting in 1923 he conducted several global gravity surveys on voyages on submarines, particularly to and in the Indonesian Archipelago. He detected strong gravity anomaly belts running parallel to the Indonesian deep sea trenches. He explained these Meinesz belts as sites of downbuckling of the Earth's crust. He introduced the concept of regional isostasy taking flexure of an elastic crust into account. He also contributed to physical geodesy: The Vening Meinesz formula connects the deviation of the vertical from the plumbline to gravity anomalies.

American mathematician who made important contributions in early topology, and in projective and differential geometry - work which found applications in atomic physics and the theory of relativity. In 1905, he proved the Jordan curve theorem, which states that every non-self-intersecting loop in the plane divides the plane into an "inside" and an "outside". Although it may seem obvious in its statement, it is a very difficult theorem to prove. During WW II, he was involved in overseeing the work that produced the pioneering ENIAC electronic digital computer. His name is commemorated by the American Mathematical Society's Oswald Veblen Prize. Awarded every five years, it is the most prestigious award in recognition of outstanding research in geometry.«

His major report was published in 1873. Pumpelly sensed the increasing importance of steel, and advised investors to search for iron rather than gold. Some who followed his advice made fortunes. He surveyed the coal fields of China (1864) and made the first extensive survey (1865) of the Gobi. He journeyed across Siberia by sleigh. Pumpelly found evidence that central Asia had once been occupied by vast inland seas or lakes, which had slowly diminished in size, leaving behind the Aral Sea and numerous small lakes.

Henry Gwyn-Jeffreys Moseley was an English physicist who experimentally demonstrated that the major properties of an element are determined by the atomic number, not by the atomic weight, and firmly established the relationship between atomic number and the charge of the atomic nucleus. He began his research under Ernest Rutherford while serving as lecturer at the Univ. of Manchester. Using X-ray photographic techniques, he determined a mathematical relation between the radiation wavelength and the atomic numbers of the emitting elements. Moseley obtained several quantitative relationships from which he predicted the existence of three missing elements (numbers 43, 61, and 75) in the periodic table, all of which were subsequently identified. Moseley was killed in action during WW I.

American photographer and manufacturer who made the first U.S. self-portrait photograph (a daguerrotype, Nov 1839), opened the first U.S. portrait photography studio (Feb 1840), and published the first photographic advertisement. He was helped by his prior study of chemistry. That enterprise he operated only as a side-interest until 1843, for his life's career was with the business started by his father, the leading maufacturer of oil lamps and gas fixtures. After 1831, when he became a partner, the business was known as Cornelius and Son. He is creditted with designing mechanical devices to facilitate the various factory processes in working metal. Before the availability of gas, the “solar lamp” he invented and patented (U.S. No. 3030, 1843) enabled burning simple lard (from fatted pigs: “prairie whales”) instead of more expensive whale oil.«[Image: detail from Cornelius self-portrait daguerrotype, believed to be the earliest extant American portrait photo, and is now in the Library of Congress.]

Other achievements of Aepinus include improvements to the microscope, and his demonstration of the effects of parallax in the transit of a planet across the Sun's disk (1764).Image: Aepinus Condenser,1880
German mathematician and physicist whose Tentamen theoriae electricitatis et magnetismi (1759; "An Attempt at a Theory of Electricity and Magnetism") was the first work to apply mathematics to the theory of electricity and magnetism. Aepinus' experiments led to the design of the parallel-plate capacitor, a device used to store energy in an electric field. He also discovered the electric properties of the mineral tourmaline and investigated pyroelectricity, the state of electrical polarization produced in tourmaline and various other crystals by a change of temperature.

On 8 Aug 2010, the record low surface temperature in Antartica was -135.8ºF (-93.2ºC), colder than the freezing point of dry ice. It was determined from analysis of remote-sensing satellite data later announced on 9 Dec 2013 at the annual meeting of the American Geophysical Union. The location was in pockets scattered near a high ice ridge between Dome Argus and Dome Fuji, two summits on the East Antarctic Plateau. August is winter in the Southern Hemisphere, and the temperature resulted from the geographical nature and weather conditions in the pockets. The World Meteorological Organization official records are for air temperatures made a couple of meters above the surface. That recorded lowest temperature, made in Jul 1983 at the Vostok Research Station, Antarctica, remains at -128.6ºF (89.2ºC).«
In 1990, the space probe Magellan arrived at its planned polar orbit around Venus. As the planet rotated slowly beneath it, Magellan circled once every 3-hr 15-min, collecting radar images of the surface in strips about 17-28 km (10-17 mi) wide and radioed back the information. Magellan was carried into space in the shuttle cargo bay of STS-30 Atlantis, launched 4 May 1989, and was the first planetary spacecraft to be released from a shuttle in Earth orbit. The Magellan mission also provided gravity, atmospheric and other measurements. On 11 Oct 1994, it was directed towards the surface, collecting data until it broke up and partially vaporized in the atmosphere.«
In 1960, an ejected space capsule from Discoverer 13 was recovered when it returned from orbit; it was the first human-made object recovered from space.
In 1904, Ford Motor Company of Canada was organized when Henry Ford signed an agreement with Gordon McGregor, a Canadian wagon builder. McGregor, age 31, had taken the initiative to vist Ford in Detroit earlier in the year because he wanted to begin making cars at his wagon works in Windsor, Ontario. Incorporation of Ford Motor Company of Canada was in the form of a Provinicial Charter issued on 17 Aug 1904. McGregor would finance his own operation, and 51% of the stock would be assigned to the Shareholders of Ford U.S.A. McGregor also obtained the rights to sell Ford products in the then existing British Empire outside of the British Isles. This foresight led to Ford of Canada to later having wholly-owned subsidiaries in Australia, New Zealand and South Africa.«

In 1859, the first full-time Inspector of Milk in the U.S. was appointed by the city of Boston, Massachusetts, as authorized by a state law passed on 6 Apr 1859. Three years earlier, a state law against adulteration of milk had been signed by the Governor (30 May 1856), but it was ineffective, as it depended on individuals making a claim in court. The 1859 law provided an official to crack down on fraud. It established a ten dollar fine for selling “swill milk,” the poor, thin output of cows kept in unsanitary conditions and fed on distillery refuse. Contaminated milk was a serious public health hazard, sometimes deadly to infants. A milk inspector was authorized to enter the premises of handlers of milk and to take specimens for analysis, the results of which were to be held as evidence and used for prosecution.«[Image: A New York City inspector at a grocery testing milk with a lactometer, c.1887] more

In 1846, an Act of Congress signed by President James K. Polk established the Smithsonian Institution as a trust to administer the generous bequest of James Smithson, an amount over $500,000. In 1826, James Smithson, a British scientist, drew up his last will and testament, naming his nephew as beneficiary. Smithson stipulated that, should the nephew die without heirs (as he would in 1835), the estate should go “to the United States of America, to found at Washington, under the name of the Smithsonian Institution, an establishment for the increase and diffusion of knowledge among men.” The motives behind Smithsons bequest remain mysterious; he had never traveled to the U.S. and seems to have had no correspondence with anyone there.

In 1675, King Charles II laid the foundation stone of the Royal Observatory, Greenwich. It had been created by Royal Warrant from the King on 22 Jun 1675. The building was designed by Sir Christopher Wren (who was also a Professor of Astronomy). Construction was finished the following year. John Flamsteed was appointed as the first Astronomer Royal. Its primary uses were very practical—using astronomy for navigation and timekeeping by determination of star positions. In 1767 the observatory began publishing The Nautical Almanac, which established the longitude of Greenwich as a baseline for time calculations. This led in part to the international adoption (1884) of the Greenwich meridian as the Earth's prime meridian.«
