Soviet physicist who, in 1941, recognized that uranium undergoes spontaneous fission (needing no neutron bombardment). He was one of the early Russian investigators of nuclear fission. In early 1942 , Flerov noticed that articles on nuclear fission were no longer appearing in western journals. Recognizing the implication that such research had become secret, he wrote to Premier Joseph Stalin, insisting that "we must build the uranium bomb without delay," (subsequently led by Igor V. Kurchatov.) In later research, Flerov announced synthesis of isotopes of element 104 (1965) and 106 (1974). Co-discoveries were made in the U.S. Several names were suggested. Eventually the adopted names were rutherfordium and seaborgium.«

German electrical engineer who invented the Phase Alternating Line (PAL) colour television system adopted in Europe. On a trip to America in 1953, he found inadequacies in the system as first developed there (NTSC, National Television Standards Committee). He returned to German employer, Telefunken, and researched a way to improve colour stability without need for tint and hue controls. By 1961, a preliminary patent was filed, but was superceded on 30 Dec 1962 with a definitive version of the PAL system. There followed a struggle for to be recognized as the best coding method. Britain selected PAL as superior to NTSC and introduced it on 1 Jul 1967. Germany followed on 25 Aug 1967. Eventually most of the world, too.«

Edward Uhler Condon was an American physicist who is remembered for the Franck-Condon principle (1928), development of radar and contributing to the design of magnetic separation equipment subsequently applied to process uranium for atomic bombs. The Franck-Condon principle (1928) is a quantum-mechanical treatment of the earlier statement by James Franck (1925) that in any molecular system the transition from one energy state to another occurs so near to instantaneously that the nuclei of the atoms involved are stationary. During the Manhattan project, he assisted J. Robert Oppenheimer assemble the team of scientist that created the first atomic bombs at Los Alamos, N.M. He led a scientific study of UFO's, which found no credible evidence.«

American locksmith and inventor who patented the laminated steel padlock, and founder of Master Lock Company (1921). As a locksmith, Soref had realized that the cheaper padlocks, made with stamped metal sheels, were poor security because they were easily damaged. He patented (1924) his invention of a laminated padlock which, like bank vault doors and battleships, was built in laminations of layer on layer of steel for greater strength. Unable to sell his invention to a padlock manufacturer, he began making them himself. Master Lock opened its first tiny factory in Milwaukee, Wisc. In 1928 Master Lock gained national recognition for shipping 147,600 padlocks to federal prohibition agents in New York for locking up the speakeasies they raided.« more

English pharmacologist and medical researcher who found an effective treatment for puerperal (childbed) fever and improved the treatment of burns. Puerperal fever resulting from infection after childbirth or abortion had affected women for centuries with severe abdominal pain, or even death. Coleman read of Domagk’s successful use of Protonsil, the first sulfonamide drug, against streptococcal infection in tests on mice and a few human subjects. In 1936, Coleman published the results of his clinical trial of Protonsil curing streptococcal puerperal fever, and launched a new era of antimicrobial chemotherapy. During WW II, he supervised the use of sulphonomides in the military. He then investigated control of infection in burns.«

Prince Boris Borisovich Golitsyn was a Russian physicist and seismologist who developed scientific methods and instruments for earthquake observations and mineral prospecting. His early studies were in molecular physics, mathematical physics and electromagnetism, From 1899 his interests turned to seismology. In 1906, he invented the first effective electromagnetic seismograph and continued to improve it. It had a pendulum carrying a coil of insulated wire around a magnetic core fixed to the ground. The small current generated in the coil by relative motion caused by earth tremors is amplified to operate a pen recorder. The part of the Earth's mantle at a depth of 400-800 km, in which seismic waves travel rapidly, is named the Golitsyn layer in recognition of his work.«[Name also spelled Galizin ot Golicyn.

American physicist who was a pioneer in condensed-matter physics investigating the physical and chemical properties of materials, and contributed to the fields of nuclear physics. He was Eugene Wigner's first doctoral student. Late in 1932, their joint work developed the cellular method of deriving solid-state wave functions. Use of this Wigner-Seitz method is now widespread. By the time he was 29 years old, Seitz’s book, The Modern Theory of Solids (1940) was his 24th publication. His treatment of all properties of all solids in terms of the electronic structure provided an outline distinguishing the field of solid state physics. Seitz was prominent in debating threats of nuclear weapon proliferation and global warming.«

American mathematician, a topologist, who led development of “new math.” When the Soviet Union launched the Sputnik satellite (1957), beating the U.S. into space, the effectiveness of science and mathematics education in American schools came under scrutiny. Begle's idea was to replace the traditional focus on mathematics as memorization and algorithmic computation. Instead, he designed a program to emphasise the fundamental importance of understanding the principles of mathematics. He directed (1958-72) the School Mathematics Study Group, funded by the National Science Foundation. SMSG produced teaching materials for all grade levels with this approach. Ultimately, initiating lasting reform through teachers was unsuccessful.«

Italian sociologist, criminologist and statistician who extended his original career as a criminologist into a study of the criminal from biological and psychology viewpoints. Then to understand the normal man in his social environment, he applied statistics to analysis of social phenomena. He proposed that every person has a “deep ego’' of driven by subconscious primitive instincts for antisocial, egotistical or infantile behaviour. This co-exists with a “superior ego” responsible for social-adjusted attitudes of values, rules and norms. A person’s conduct is the result which of these is dominant. He published this theory in 1902, in La transformation del delito and continued to publish further elaborations upon it for years later.«

German botanist whose natural system of plant classification (1886) was one of the first to become widely adopted. He studied the symmetry of the parts of a flower. His system of plant classification was based on earlier work of de Jussieaus and others. Eichler assumed complexity indicated more advanced development. His plant kingdom had four divisions: Thallophyta: algae, fungi; Bryophyta: liverworts, mosses; Pteridophyta: club mosses, horsetails, ferns; Spermatophyta: seed plants (angiosperms: flowering plants and gymnosperms: pines, spruces, and firs). Eichler wrote a syllabus of pharmaceutical botany and made significant collection on the flora of Brazil.«

In 1969, the Concorde SST Supersonic jet aircraft, prototype 001, made its first flight from Toulouse airport in France. With tons of test instruments aboard, test pilot Captain Andre Turcat took off at 3:40 pm, followed by two chase aircraft for filming the historic flight, and for calibration purposes. The flight lasted only about a half hour, remaining at a subsonic speed with its landing gear and nose in the down position. The aircraft made a clean landing at 4:08 pm. It was not the first supersonic-capable airliner to fly, however, as the Russian Tupolev-144 first flew several months earlier, on 31 Dec 1968. The British prototype Concorde 002 made its first flight from Filton Airport, Bristol on 9 Apr 1969. It was not until its 45th test flight, on 1 Oct 1969, that prototype 001 flew at a supersonic speed, above Mach 1.«

In 1949, the first round the world nonstop airplane flight was completed in a U.S. Air Force B-50 Superfortress bomber, the Lucky Lady II with a crew of 14 headed by Captain James Gallagher. They landed back at Carswell Air Force base, Fort Worth, Texas, which they had left on 26 Feb 1949, about 94 hours earlier. The airplane was refueled several times in midflight on its 23,452 journey. Its average speed was 249-mph. This was at the time of the Berlin Airlift and the Cold War. The flight showed that the USAF was capable of projecting air power anywhere in the world. The first jets - three U.S. Air Force B-52 Stratofortress bombers - to fly nonstop around the world - took 45 hours (16-18 Jan 1957), completing 24,325 miles at an average speed of 525-mph.«

In 1825, work began on the Thames Tunnel in London, the world's first tunnel under a navigable river, between Rotherhithe and Wapping. Excavation was engineered by Marc Brunel, for which he used a tunneling shield to reduce the danger of collapse while digging through soft sediments. Beginning his own engineering career, his son Isambad K. Brunel assisted. Together they persevered through 18 years, dealing with floods, human disasters, and delays caused by financing difficulties. It opened for pedestrians on 25 Mar 1843. Planned ramps for use by carts and freight traffic were never added due to cost. The tunnel re-opened with a railway line on 7 Dec 1869, and it continued in use as the oldest part of the London Underground.«[Image: detail of the first vertical shaft excavated for access to Thames Tunnel, Rotherhithe, showing workers and ladders between floors.] more
