| Robert B. Laughlin | |
(aource) |
American physicist who (with Daniel C. Tsui and Horst Störmer) received the Nobel Prize for Physics in 1998 for research on the fractional quantum Hall effect. In a current-carrying conductor, the classic Hall effect is the voltage produced at right angles to a magnetic field, as first discovered in 1879. A century later the German physicist Klaus von Klitzing discovered that in a powerful magnetic field at extremely low temperatures the Hall resistance of a semiconductor is quantized in integral "steps". Using even stronger magnetic fields and lower temperatures, Störmer and Tsui discovered fractional steps, explained by Laughlin's theory that the electrons can form a new type of quantum fluid with quasiparticles carrying fractions of an electron's charge. |
| Sir Hermann Bondi | |

Austrian-born British mathematician and cosmologist who, with Fred Hoyle and Thomas Gold, formulated the steady-state theory of the universe (1948). Their theory addressed a crucial problem: "How do the stars continually recede without disappearing altogether?" Their explanation was that the universe is ever-expanding, without a beginning and without an end. Further, they said, since the universe must be expanding, new matter must be continually created in order to keep the density constant, by the interchange of matter and energy. The theory was eclipsed in 1965, when Arno Penzias and Robert Wilson discovered a radiation background in microwaves giving convincing support to the "big bang" theory of creation now accepted. |

American physicist who invented the betatron (1940), the first device to accelerate electrons ("beta particles") to speeds high enough to have sufficient momentum to produce nuclear transformations in atoms. The electrons are accelerated by electromagnetic induction in a doughnut-shaped (toroidal) ring from which the air has been removed. This type of particle accelerator can producing high-energy electrons up to 340 MeV for research purposes, including the production of high-energy X-rays. For such high velocities, the magnetic field is increased to match the relativistic increase in mass of the particles. During WW II, Kerst worked at Los Alamos on tue atomic bomb project. He completed the largest betatron in 1950, at the University of Illinois. |

Sir Gavin Rylands de Beer was an English zoologist and morphologist who contributed to experimental embryology, anatomy, and evolution. He refuted the germ-layer theory and developed the concept of paedomorphism (the retention of juvenile characteristics of ancestors in mature adults). From examination of the fossil Archaeopteryx, De Beer proposed mosaic evolution with piecemeal evolutionary changes to explain the combination of bird and reptile features. He was director of the British Museum's Natural History section (1950-60). Applying knowledge of biology (plant pollen) and geology (glaciology) to his study of original documents, he proposed the route taken by Hannibal across the Alps for his attack on ancient Rome. |
| Anton Flettner | |

German inventor who produced a practical helicopter for the German navy (1940). He also developed a device that allowed airplane pilots to raise or lower a plane's nose for better control. It evolved into a mechanism called the Flettner trim-tab control which is still used on all airplanes. He designed a rotor ship (1924) on which he replaced sails with unique propulsion - two 50-ft cylinders, electrically rotated, mounted vertically on the deck. A transatlantic voyage was accomplished using the aerodynamic power of the Magnus Effect which builds pressure behind a rotating cylinder. After WW II, he went to the U.S., and conducted helicopter research for the U.S. Army. He also invented a windmill and the Flettner marine rudder.« |
| Alfred L. Wegener | |

Alfred Lothar Wegener was a German meteorologist and geophysicist who first gave a well-developed hypothesis of continental drift. He suggested (1912) that about 250 million yrs ago all the present-day continents came from a single primitive land mass, the supercontinent Pangaea, which eventually broke up and gradually drifted apart. (A similar idea was proposed earlier by F.B. Taylor in 1910.) Others saw the fit of coastlines of South America and Africa, but Wegener added more geologic and paleontologic evidence that these two continents were once joined. From 1906, interested in paleoclimatology, he went on several expeditions to Greenland to study polar air circulation. He died during his fourth expedition. |
| Oskar Barnack | |

German engineer who designed the first miniature camera (1913), the Leica I. Its commercial introduction, delayed by WW I, was made in 1924 by the Ernst Leitz optical firm at Wetzlar, Germany where he was employed. Barnack was an enthusiastic photographer from when only heavy plate cameras were available. As early 1905, he conceived using a reduced format negative, to be enlarged after exposure. He adapted his idea from equipment he made to take still exposures on samples of cine film to test their sensitivity and consistency before movie use. For this camera, Barnack established the standard 35-mm film picture size by doubling the standard 18x24mm cine frame. His invention had only 1/250 of the weight of a plate camera. |

George Safford Parker was an American inventor who perfected the fountain pen and founded the Parker Pen Company to manufacture it. He began in a teaching career which introduced him to the unreliability of existing fountain pens used by his students. Through selling and repairing them, he learned of their construction. He ceased teaching in 1888 to experiment with his own design. By 8 Mar 1892, he incorporated Parker Pen Company. He subsequently patented many improvements, and was particularly successful in creating a reliable ink-flow system. During WW I, his Trench Pen utilized a tablet of pigment to be inserted into the pen and turned to fluid ink by filling the barrel with water. |

Irish geologist, physicist and inventor whose interests spanned several fields. Using Edmond Halley's method of measuring the degree of salinity of the oceans, and then by examining radioactive decay in rocks, he estimated Earth's age at 80-90 million years (1898). Later, he revised this figure to 100 million years. He published Radioactivity and Geology (1909) in which he demonstrated that the rate of radioactive decay has been more or less constant through time. He also developed a method for extracting radium (1914) and pioneered its use for cancer treatment, and invented a constant- volume gas thermometer, a photometer, and a differential steam calorimeter for measuring the specific heat capacity of gases at constant volume. |
| Giacomo Doria | |
Italian naturalist and explorer who conducted important research in systematic zoology. Pursuing his work, he made expeditions to Persia (1862), Borneo (1865-66) and Tunisia (1879). In 1867, he founded the civic museum of natural history in Genoa. The collection he donated became the nucleus of the museum, which he directed for more than 40 years. He was also director of Societa Geografica Italiana (1891-1900). The museum he founded now contains important zoolological, paleontological, botanical, and mineralogical collections from all over the world. These collections are continually growing, now estimated to be more than 3.5 million exhibits. |

Scottish meteorologist and geophysicist noted for his studies of terrestrial magnetism and radiant heat. His researches on radiant heat contributed to foundation of spectrum analysis. He was the first to discover that bodies radiate and absorb energy of the same wavelength. In meteorology, he pioneered in ionospheric science, making a special study of terrestrial magnetism. He proposed (1882) that the daily variation in the Earth's magnetic field could be due to air currents in the upper atmosphere, which act as conductors and generate electrical currents as they pass through the Earth's magnetic field. He also investigated sunspots. In 1887, he died, age 59, soon after suffering a stroke while crossing to spend Christmas at his estate in Ireland. |

Crawford Williamson Long was an American physician who was the first in the U.S. to use ether as anesthetic in surgery. On 30 Mar 1842, practicing in rural Georgia, he first used ether anesthetic while he removed a tumour from a patient's neck. Although he operated more times with ether before 1846, he was apparently unaware of its full significance and did not publish a description of his procedure until 1849. By that time, W.T.G. Morton of Boston had filed a patent for discovery of ether in 1846 and Long would never get much credit or gain from claim to priority. In 1850, he moved to Athens, Georgia, acquiring a large practice and an apothecary shop. There he used ether in obstetrical cases and did much charitable work for the poor. |

American chemical engineer who inventedPampers disposable diapers. He joined Proctor& Gamble company in 1926, and soon after developed a continuous process to superheat the liquid soap and spray it in concentrated form through an extruder producing bars of Ivory soap. That cut the production time from seven days to just a couple of hours. He improved Duncan Hines cake mixes by passing ingredients through large milling drums designed to polish aluminum foil but made the finished cake less lumpy. He developed a process for preventing the oil from separating in Jif peanut butter. His invention of disposable diapers as a product was created to utilize the clean, absorbent paper available from a pulp mill acquired by the company. |
| Alexander George McAdie | |
1893 (source) |
American meteorologist who was a pioneer in employing kites in the exploration of high altitude air conditions. As a college graduate, McAdie in Jan 1882 joined the Army Signal Service, which preceded the civilian U.S. Weather Bureau. He invented and patented devices to protect fruit from frost. He examined the influence of smoke pollution on the atmosphere, McAdie studied the relation between atmospheric electricity and auroral phenomena, and wrote about lightning as a hazard both in the air and on the ground. He believed that the units used in meteorology should be standardized by adoption of the metric system. McAdie was a founder of the Seismological Society of America. Mt. McAdie (13,799 ft.) in the Sierra Nevada was named for him. [Image: Cloud and Multiple Flash from Pop. Sci. Monthly, 1893] |
