 Born 28
Aug 1919; died 12 Aug 2004.
English electrical engineer who shared the 1979 Nobel Prize for Physiology or Medicine (with Allan Cormack) for creation of computerised axial tomography (CAT) scanners. He originated the idea during a country walk in 1967 when he realized that the contents of a box could be reconstructed by taking readings at all angles through it. He applied the concept for scanning the brain using hundreds of X-ray beams imaging cross-sections that were reconstructed as high-resolution graphics by a computer program handling complex algebraic calculations. By 1973 his CAT scanner could produce cross-section images of a brain in 4-1/2-min, invaluable for the diagnosis of brain diseases. He later built larger machines able to make a full body scan.«  Godfrey

Born 28
Aug 1903; died 13 Mar 1990.
Austrian-born American psychologist known for his work in treating and educating emotionally disturbed children. Bettelheim was a revered author of influential clinical studies on the lives of autistic children as well as popular Freudian interpretations of myth and fairy tale; and founder of the Orthogenic School of psychoanalysis in Chicago. After his suicide, at the age of 86, a scandal followed when his reputation as a benevolent sage was besmirched by former patients who claimed that he had sadistically beaten them. |

Born 28
Aug 1878; died 1 Feb 1976.
George Hoyt Whipple was an American pathologist who shared the 1934 Nobel Prize for Physiology or Medicine with George R. Minot and William P. Murphy for "their discoveries of a treatment of pernicious anemia with a special diet of liver." Whipple began a study in 1920 of the influence of food on blood regeneration. From experiments on dogs bled to reduce blood volume, he found the best food to stimulate the bone marrow for the production of the new red blood corpuscles was raw liver. Other foods, including kidney and apricots were also found helpful. Minot and Murphy applied Whipple's discovery of the value of liver. They designed a special diet for humans with a particular noninfectious disease - pernicious anemia. The three researchers made a major advance with a non-drug treatment of this condition.« George

| Charles Stewart Rolls | |
| Born 28
Aug 1877; died 12 Jul 1910
British motorist, aviator, and automobile manufacturer who was one of the founders of the Rolls-Royce Ltd. automobile company. He was the first aviator to fly across the English Channel and back nonstop (June 1910). Rolls drove a 12-hp Panhard car in the Thousand Miles Trial of 1900 and took part in many of the early long-distance European classic races. In 1902 he became a motor dealer and in 1906 merged his firm with that of Sir Henry Royce to form Rolls-Royce Ltd. Rolls died in a flying accident, the first British pilot to do so. eb |

Born 28
Aug 1863; died 15 Nov 1938.
André-Eugène Blondel was a French physicist who invented (1893) the electromagnetic oscillograph, a device that allowed electrical researchers to observe the intensity of alternating currents. In 1894, he proposed the lumen and other new photometric units for use in photometry, based on the metre and the Violle candle. Endorsed in 1896 by the International Electrical Congress, his system is still in use with only minor modifications. Blondel was a pioneer in the high voltage long distance transport of electric power, and also contributed to developments in wireless telegraphy, acoustics, and mechanics. He proposed theories for induction motors and coupling of a.c. generators.« |

Born 28
Aug 1801; died 31 Mar 1877.
French economist and mathematician, who was the first economist who applied mathematics to the treatment of economic questions. In 1838, he published Recherches sur les principes mathématiques de la théorie des richesses (Researches into the Mathematical Principles of the Theory of Wealth) which was a treatment of mathematical economics. In particular, he considered the supply-and-demand functions. Further, he studied the conditions for equilibrium with monopoly, duopoly and perfect competition. He included the effect of taxes, treated as changes in production costs, and discussed problems of international trade. His definition of a market is still the basis for that presently used in economics. In other work, he applied probability to legal statistics.« |

Paul Beattie MacCready was an American engineer who invented not only the first human-powered flying machines, but also the first solar-powered aircraft to make sustained flights. On 23 Aug 1977, the pedal-powered aircraft, the Gossamer Condor successfully flew a 1.15 mile figure-8 course to demonstrate sustained, maneuverable manpowered flight, for which he won the £50,000 ($95,000) Kremer Prize. MacCready designed the Condor with Dr. Peter Lissamen. Its frame was made of thin aluminum tubes, covered with mylar plastic supported with stainless steel wire. In 1979, the Gossamer Albatross won the second Kremer Prize for making a flight across the English Channel.«

28 Aug 1966 (born 31 Mar 1907)
U.S. microbiologist who researched arthropod-borne viral diseases such as rabies and encephalitis. While working for the Rockefeller foundation, Johnson isolated a strain of virus from the spinal chord of a 14-year-old girl that died from rabies, introduced the virus to the brain of young chicks, transferred from one chick to another 138 times. In 1945, he gave a sample of this Flury virus (named after the girl) to Dr Hilary Koprowski who spent another ten years developing from it a new vaccine eventually used for dogs in the 1960's. In later work, Johnson took an ecological approach to understanding diseases transmitted by animals and travelled extensively to track down the natural foci of disease agents in wildlife.« Rabies,

28 Aug 1940 (born 6 May 1872)
American geodesist who investigated isostasy, a principle that rationalizes the tendency of dense crustal rocks to cause topographic depressions and of light crustal rocks to cause topographic elevations. He made systematic observations of gravity anomalies on land and encouraged gravity surveys in the oceans. He found the anomalies correlated with topographic features and validated the isostasy phenomenon. With John F. Hayford, he computed tables of the depth of isostatic compensation (the surface above which the weight of the crust per unit area is equalized). Bowie felt that this zone would occur at a uniform depth as predicted by John Henry Pratt, rather than at the varying depth predicted by Sir George Airy. He wrote Isostasy (1927). |

28 Aug 1934 (born 28 Jan 1858)
Sir T(annatt) W(illiam) Edgeworth David was a Welsh-born Australian geologist who produced an extensive study of the geology of Australia, including the first geological map of the Sydney-Newcastle Basin. He also researched the evidence of major glaciations in Australia of the Upper Paleozoic time (from 345- to 225- million years ago). In 1897, he drilled to a depth of 340-m at Funafuti Atoll in an effort to verify Darwin's theory of the formation of coral atolls. Whereas his results supported Darwin's ideas, they were short of absolute proof. He served as scientific officer of the Shackleton Antarctic Expedition from 1907-9, and led the party that first reached the southern magnetic pole on 16 Jan 1909, which was on land at that time.« |
| Emile Haug | |

Died 28 Aug 1927 (born 19 Jun 1861)
Gustave-Émile Haug was a French geologist and paleontologist known for his contributions to the theory of geosynclines (trenches that accumulate thousands of metres of sediment and later become crumpled and uplifted into mountain chains). From the position of the Alp he theorized that geosynclines form between stable continental platforms. He showed that geosynclinal subsidence accompanies marine regressions on the continental platform and that geosynclinal uplift accompanies marine transgressions on the continental platform. His Traité de géologie (1907-11), rapidly became an indispensible reference work. He also produced important works on the fundamentals of paleotology, stratigraphy and tectonics.

Died
28 Aug 1880 (born 21 Jun 1805)
American physician, chemist, and pioneer geologist and mineralogist. Jackson's professional career consisted of a series of spectacular claims to the work of others which continued until he finally became insane in 1873. In 1832, during a voyage, he discussed with the portrait painter Samuel Morse the possibilities of electric telegraphy. Morse exhibited his telegraph to Congress in 1837 but had to spend seven years to establish a right to his own invention against Jackson's claim that Morse had stolen it from him. Jackson similarly claimed priority in the idea of use of ether as an anaesthetic, which he had suggested to a dentist, William Morton. Though the effects of ether were somewhat known at the time; it was Morton who made the idea practical. |
| Stephen McCormick | |
| Died
28 Aug 1875 (born 26 Aug 1784)
American inventor and manufacturer of a practical cast iron plow with detachable components. An earliest achievement was to increase the productivity of a water-powered grist-mill by improving the shape of its nether millstone (the lower of the two millstones used to grind flour). By 1816, he had invented, made, and used a cast-iron plough superior to Charles Newbold's earlier design. McCormick's first of several patents was issued on on 3 Feb 1819. His cast-iron mould board had an adjustable wrought-iron point mounted beneath, able to decrease the draft, while deepening the furrow, and breaking up the soil more effectively. Standardization of the replaceable parts led to the development of improved manufacturing processes.«  |

Died
28 Aug 1839 (born 23 Mar 1769)
English engineer and geologist who extended the science of stratigraphy. His early work was as a miner and an engineer, for a canal-digging company. From this experience he observed the difference in rock layers. He also recognized that the same succession of fossil groups from older to younger rocks could be found in many parts of England, which he called the principle of faunal succession. He travelled the entire country to verify that relationships between the strata and their characteristics were consistent everywhere. Thus Smith created a profile of the entire country of England. His great geologic map of England and Wales (1815) set the standard for modern geologic maps. Many of the colourful names he gave to the strata are still in use today.« [Image: portrait of William Smith by Abner Lowe in the 1920s] The

| Asteroid's moon | |
(source) |
In 1993, a picture was taken showing the first moon of an asteroid. The
asteroid 243 Ida and its newly-discovered moon, Dactyl was imaged by NASA's
Galileo
spacecraft, about 14 minutes before its closest approach (within 2,400-km
or 1,500 miles) to the asteroid. Ida is about 52 km (32 mi) in length and
is irregularly shaped. It shows numerous craters, including many degraded
craters, indicating Ida's surface is older than previously thought. Dactyl
is only about 1.4-km in diameter, and it is spectrally different from Ida
data. The picture was released on 26 Mar 1994. Galileo had encountered
the first asteroid - 951 Gaspra - on 29
Oct 1991. Galileo continued on its mission to study Jupiter,
beginning its orbit of the planet on 7 Dec 1995. |
| Floating bridge | |
(source) |
In 1963, the longest floating pontoon bridge
in the world opened. The Evergreen Point Floating Bridge, connecting Seattle
and Bellevue carries state road 520 with a floating length of 7,578 ft
- almost 1000-ft more than the second-longest bridge (Lacey V. Murrow Bridge).
Like the Hood Canal Bridge, the 520 bridge has a retractable drawspan in
the middle, which is opened to protect the bridge when the windspeed reaches
40mph. Experts believe the bridge will reach the end of its useful life
by 2025, by which time at least the pontoons will have to be replaced.
However, it already has been plagued by crippling mechanical problems over
the past ten years. On 3 Mar 1999, it was stuck open when one of the drawspan
rollers broke.« |

In 1845, the first issue of the Scientific
American was published
by Rufus Porter (1792-1884), a versatile if eccentric Yankee, who was by
turns a portrait-painter, schoolmaster, inventor and editor. While the
paper was still a small weekly journal with a circulation less than 300,
he offered it for sale. It was bought for $800 in July 1846 by 20-year-old
Alfred Ely Beach (1826-1896) as editor, and Orson Desaix Munn (1824-1907).
Together, they built it over the years into a great and unique periodical.
Their circulation reached 10,000 by 1848, 20,000 by 1852, and 30,000 by
1853. |
