Posted by Christie Davies Science we are told is something that every child should and must study. Most children hate it, fail to master it and never use it or think about it again after they have left school. It is forced upon unwilling and inept pupils because it is supposed to be good for them.
Born 15 May ; died 19 Apr at age His studies of radioactive substances were made together with his wife, Marie Curie, whom he married in They were achieved under conditions of much hardship - barely adequate laboratory facilities and under the stress of having to do much teaching in order to earn their livelihood.
Together, they discovered radium and polonium in their investigation of radioactivity by fractionation of pitchblende announced in Later they did much to elucidate the properties of radium and its transformation products.
Their work in this era formed the basis for much of the subsequent research in nuclear physics and chemistry. Fleming Born 15 May ; died 21 May at age Edward Pickering, director of the Harvard Observatory first employed Fleming as a maid, but in hired her to do clerical work and some mathematical calculations at the Observatory.
She further proved capable of doing science. After devising her system of classifying stars by their spectra, she cataloged over 10, stars within the next nine years.
Her duties were expanded and she was put in charge of dozens of young women hired to do mathematical computations as now done by computers. German neurologist who related nerve diseases to specific areas of the brain.
Interested in psychiatry, traditionally he studied anatomy initially and neuropathology later. He published a small volume on aphasias disorders interfering with the ability to communicate in speech or writing which vaulted him into international fame.
In it was precise pathoanatomic analysis paralleling the clinical picture. He is best known for his work on sensory aphasia and poliomyelitis hemorrhagia superior. Both of these descriptions bear his name, as well as a form of encephalopathy induced by thiamine deficiency.
He wrote books on the disorders of the internal capsule and textbooks on diseases of the nervous system. Wernicke died in a road accident. He was one of the first to describe protozoan parasites found in the blood of vertebrates.
Lankestrella a parasite related to the causative agent of malaria carries his name. His work contributed to an understanding of the disease. Based on his investigation into the comparative anatomy of the embryology of invertebrates, Lankester endorsed Darwin's theory of evolution, In anthrolopology, his activities included the discovery of flint implements, evidence of early man, in Pliocene sediments, Suffolk.
After the civil war, while still an army officer, fromhe assisted in Powell's survey of the Rocky Mountains. From until his retirement from the army inhe worked for the U.
He made geological investigations of the Grand Canyon in Colorado, the plateaus of Utah, and the Charleston earthquake. In seismology, he pioneered a method to determine the depth of the focus of an earthquake and the speed of its seismic waves.
Inhe became the first head of the USGS division of volcanic geology. Henri Mouhot Born 15 May ; died 10 Nov at age He is remembered for his reports of the ruins of Angkor, capital of the ancient Khmer civilization of Cambodia.
The location was known to the local population, had been visited by several westerners since the 16th century, but it was Mouhot's evocative accounts and detailed sketches that popularized the Angkor series of sites with the western public. He drew the attention of western scholars to the many ancient terraces, pools, moated cities, palaces and temples as important archaeological sites.
His books were published posthumously as he died in Laos at the young age of 35 from malarial fever on his fourth jungle expedition.
Joseph Loschmidt Born 15 May ; died 8 Jul at age He deduced the size of air molecules to be around one nanometer, with two approaches: Completing Avogadro's insight that all gases have the same number of molecules in a given volume, Loschmidt measured Avogadro's constant to be 6.How Invention Begins: Echoes of Old Voices in the Rise of New Machines [John H.

Bibliography. Biographies for and images of Past Presidents of the Institution of Mechanical Engineers (IMechE) starting with our first President in , George Stephenson. Includes portrait pictures. Air Commodore Sir Frank Whittle OM KBE CB FRS FRAeS (1 June – 9 August ) was a British Royal Air Force air officer.
He is credited with single-handedly inventing the turbojet engine. A patent was submitted by Maxime Guillaume in for a similar invention; however, this was technically unfeasible at the yunusemremert.com: 1 June , Earlsdon, Coventry, England.
