Science Teachers’ Assocation of NSW inc 2016/17 Calendar MONDAY TUESDAY WEDNESDAY THURSDAY 1 1903; birth of English physicist Cecil Powell, who won the 1950 Nobel Prize for Physics for his development of the photographic method of studying nuclear processes and consequent discovery of the pion, a heavy subatomic particle. 5 1888; birth of Libby Henrietta Hyman, a US zoologist who wrote two laboratory manuals and a comprehensive six-volume reference work, ‘The Invertebrates from 1940-67 covering most phyla of its subject, a fine reference still in use. 6 DECEMBER 1805; birth of Johann von Lamont, a Scottish scientist who discovered that the magnetic field of Earth fluctuates with a 10.3-year activity cycle, but it does not correlate with the period of the sunspot cycle. 12 13 2004; Herbert Brown died; he was an English chemist who developed organoboranes, opening up many new techniques in synthetic organic chemistry. For this he shared the 1979 Nobel Prize for Chemistry. 19 Boxing Day 26 20 1910; Ian Donald, an English physician, was born. Having become familiar with sonar in WW2 he was first to probe organs with ultrasound when he investigated tumours in human organs with an industrial metal flaw detector. 1816; Cláudio Villas-Boas, was born. He was a Brazilian anthropologist and activist whose life was dedicated to finding and protecting indigenes whose lands were stolen and developed; with brother Orlando he helped create Xingu National Park. 7 1989; Soviet Andrei Sakharov died. He was a nuclear scientist; at the end of WWII he worked on cosmic rays, but 2 years later began developing a hydrogen bomb with a secret research group. He became an outspoken human rights advocate. 14 8 1916; birth of Maurice Wilkins, a New Zealand born biophysicist whose X-ray diffraction studies of DNA were significant in the determination of the molecular structure of DNA accomplished by James Watson and Sir Francis Crick. 15 1988; Dutch ethologist Nikolaas Tinbergen died. He studied behaviour of animals in their natural habitats, constructing tests to observe responses and animal aggression, to explain human violence as rooted in an animal instinct for survival. 21 JANUARY 27 28 1941; birth of Donald Keck, an American research physicist, who with colleagues Robert Maurer and Peter Schultz invented fused silica optical waveguide - optical fibre, a break-through creating a telecommunications revolution. 1932; Johan Vogt died. He was a Norwegian geologist and petrologist who pioneered in the use of physical-chemical methods in the study of the origin of igneous rocks and ores. 2004; ‘Spirit’, a robot rover landed on Mars to analyse the planet’s rocks, looking for evidence of water. It has taken the only photo of Earth from another planet. 2 3 4 1950; birth of Sir Alec Jefferys, the English geneticist who discovered the technique of DNA fingerprinting, used for unique identification of humans, animals and other organisms from their DNA material on 10 Sep 1984. 1989; Soviet rocket scientist Valentin Glushko died. He was a pioneer developer of rocket engines, working with Sergey Korolyov . In Aug 1957, they launched the first ICBM, and in October sent the first artificial satellite into orbit. 9 10 FRIDAY SATURDAY SUNDAY 2013; China launched its Chang’e-3 lunar probe carrying the Jade Rabbit rover. The spacecraft went into orbit, then on to the Moon. It was hoped to become China’s initial extraterrestrial landing craft to showcase their technological abilities. 1877; birth of Richard Pearse, a New Zealand inventor. At age 21 he stopped farming, built a workshop, and had soon patented a new type of bicycle. He built a twostroke motor by 1902, then a plane from tubular steel, wire, bamboo and canvas. 1798; Luigi Galvani, an Italian physician and physicist, died. While he investigated body organs and tissues he noticed frogs’ muscles moved if touched by two wires of distinct metals, which he believed incorrectly to be ‘animal electricity’. 2 3 1996; Mary Leakey, a British archaeologist who made several of the most important fossil finds died. Every vivid claim made by husband Louis about the origins of man, the supporting evidence came from Mary’s scrupulous scientific approach. 9 10 1968; Dorothy Garrod died. She was an English archaeologist who arranged a series of pioneering excavations from 1929-34, notably the 22-month excavation at Mt. Carmel, Palestine, spanning 200,000 years of human occupation. 16 17 18 1901; Sir Henry Gilbert died. He was an English chemist who for 50 years researched chemistry, meteorology, botany, animal and vegetable physiology and geology to determine practical improvements for agricultural methods. 1856; Hugh Miller, a Scottish geologist and theologian, died. He was self-taught, no college education, gaining his experience from time spent in the field, taking an interest in the local Devonian rocks and the fossil fish within them. 22 23 1954; Rodney Brooks was born, an Australian engineer and inventor, a pioneer in building robots with artificial intelligence. Director of MIT’s AI Lab from 1997-2007, he has also made robots for Mars (NASA), drones for Iraq and to clean floors. 30 31 1906: birth of Dame Kathleen Mary Kenyon. an English archaeologist who excavated Jericho to its Stone Age foundation, proving it to be the oldest known continuously o ccupied human settlement. 1990; Russian physicist Pavel Cherenkov died. He discovered Cherenkov radiation in 1934, a faint blue light emitted by electrons passing at speeds faster than light through a transparent medium. 1745; Danish entomologist Johann Fabricius was born. After studying with the Swede Linnaeus, he travelled widely in Europe to observe insect collections, and wrote describing all the new species he saw. 5 1729; Lazzaro Spallanzani, an Italian physiologist, was born. He showed microorganisms arise not by spontaneous generation but from spores in the air. He also studied regeneration and spermatozoa. 11 12 —4— 11 1778; birth of English chemist Sir Humphry Davy who invented the miner’s safety lamp. He epitomised the scientific method, isolating several compounds and elements (Na, K, Ca, B, Sr, Ba and Mg) by electrolysis of their salts. 1989; Austro-German rocket pioneer Hermann Oberth died. Injured in WWI, he drafted a plan for a longrange, liquid-propelled rocket the War Ministry dismissed as fanciful, yet Werner von Braun chose him to help build the V1 and V2 rockets. 29 4 1863; birth of Annie Jump Cannon, a deaf US astronomer hired by the Harvard Observatory to classify stars by their spectra. She organised the classification of stars into spectral classes O, B, A, F, G, K, M in terms of surface temperature, 6 1404; The ‘Act of Multipliers’ was passed in English Parliament to forbid alchemists from creating the precious metals gold and silver by transmutation. It had fascinated the imagination of many in England, but was made to be felony. 13 24 Christmas Day Sir Isaac Newton was born on Christmas Day, 1642. He made major discoveries in most scientific fields, such as gravity, motion, force, light and calculus and was the leading scientist of his era. 25 New Year’s Eve New Year’s Day 1934; Cornelia Maria Clapp, a US zoologist and educator, died. Her influence as a teacher was great and enduring at a time when the world of science was just opening to women. 1894; birth of Indian physicist Satyendra Bose, who collaborated with Einstein to develop a theory of statistical quantum mechanics, now called Bose-Einstein statistics. 7 1898; English mathematician and novelist Charles Dodgson (pen-name Lewis Carroll) died. He was a lecturer at Christ Church College at Oxford but was better remembered for writing “Alice in Wonderland” and its sequel. 14 1 1823; birth of Alfred Wallace, English naturalist who studied the distribution of organisms, best known for his theory of the origin of species through natural selection made independently of Darwin. 8 1850; birth of Sofia Kovalevskaya the first Russian female educated in mathematics; while just aged 11, her nursery walls were covered with pages of calculus lecture notes. She became the first female full professor in Europe. 15
