The value of citrus juice had been established by James Lind, with his Treatice on Scurvy (1754). Blane also improved sanitary conditions in the Navy by providing supplies of soap and medicines, and was involved with designing rules that were precursors to modern quarantine conditions. He required every surgeon in the service to make regular returns or journals of the state of health and disease onboard their ship. In 1829, he established a prize medal as an incentive for the surgeon producing the best journal. Pic. | ||

The largest warship in the world at the time of launching, she saw service during the Seven Years' War including being Admiral Sir Edward Hawke's flagship at the Battle of Quiberon Bay and later taking part in the Battle of Cape St Vincent. She sank undergoing routine maintenance work whilst anchored off Portsmouth on 29 August 1782 with the loss of more than 800 lives, one of the most serious maritime losses to occur in British waters.

He asserted that the infection was carried from patient to patient by physicians and nurses. Because that defied the conventional wisdom, he received abuse from the obstetricians of the time. (A few years later, Ignaz Semmelweiss demonstrated the importance of hand-washing and hygiene. Before them, John Burton in 1751, and Charles White in 1773 had suspected the role of medical attendants.) Holmes coined the term “anesthesia,” from Greek words meaning “no feeling”.

Faraday wound a thick iron ring on one side with insulated wire that was connected to a battery. He then wound the opposite side with wire connected to a galvanometer. He found that upon closing the battery circuit, there was a deflection of the galvanometer in the second circuit. Then he was astonished to see the galvanometer needle jump in the opposite direction when the battery circuit was opened. He had discovered that a current was induced in the secondary when a current in the primary was connected and an induced current in the opposite direction when the primary current was disconnected. | ||

In the U.S. it was called Joe No. 1 ("Joe" was nickname for Y. Stalin.) This event came five years earlier than anyone in the West had predicted, largely due to one man, the spy Klaus Fuchs. As a Los Alamos physicist, Fuchs had passed detailed blue prints of the original American Trinity bomb design to the Russians. With the emergence of the USSR as a nuclear rival, America's monopoly of atomic weaponry was ended giving the U.S. strong motivation for intensifying its program of nuclear testing. Thus the Cold War was launched. On 23 Sep 1949, President Truman announced the Soviet detonation to the American public. | |||

Physicists at the Heavy Ion Research Laboratory, Darmstadt, West Germany made and identified element 109 by bombing a target of Bi-209 with accelerated nuclei of Fe-58. After a week of target bombardment a single fused nucleus was produced. The combined energy of two nuclei had to be sufficiently high so that the repulsive forces between the nuclei could be overcome. The team confirmed the existence of element 109 by four independent measurements. The nucleus started to decay 5 ms after striking the detector. This experiment demonstrated the feasibility of using fusion techniques as a method of making new, heavy nuclei. | |||
||1982: The 52,000-mile “Transglobe” expedition completed the first circumnavigation of the world's polar axis. Beginning in 1979, British explorer Ranulph Fiennes with Charles Burton had travelled for three years around the Earth via the Poles circling the earth on longitude 0, the Greenwich Meridian. They had reached the North Pole on 11 Apr 1982, and the South Pole sixteen months before that. Their journey across Antarctica took 67 days, despite the advantages of motorised skidoos. The ocean voyage was undertaken in a craft named Benjamin Bowring. The expedition cost an estimated $18 million. | |||

Washington. Pic. | |||

Horace invented and built many astronomical instruments, including a ruling engine which produced excellent diffraction gratings, the solar magnetograph, and microphotometers, automatic guiders, and exposure meters for the 100 and 200-inch telescopes. By combining his polarizing analyzer with the spectrograph he discovered magnetic fields in other stars. He developed important models of sunspots and their magnetism, and was the first to propose adaptive optics (1953). Pic: https://aas.org/obituaries/horace-welcome-babcock-1912-2003 | |||
