RADIOLOGY: HISTORY OF PERSPECTIVE Cabalog K.J BSRT 1-51A Evangelista Torricelli was an Italian Isaac Newton built and improved the scientist to create a sustained vacuum and Electrostatic generator the principle of a barometer. (1643) Otto von Guericke invented the spool vacuum air pump. That was capable of removing air from a vessel/tube He also the first to build an Electrostatic generator 19th century (1649) Robert Boyle & Hermann Sprengel invented mercury vacuum pump, now known as Sprengel pump which sucked the air out of a light bulb and preserved the filament. Charles du Fay a french chemist, (1865) discovered the existence of two types of electricity and named them “vitreous” and William Gilbert of England - the first man “resinous” who study electricity and magnetism. He also invented the first electroscope Abbé Jean-Antoine Nollet made a around (1600) and it was a pivoted needle significant improvement in the called “versorium” electroscope, a vessel for discharging electricity under vacuum conditions. He William Watson demonstrated a current of electricity by transmitting electricity from a Leyden Jar through wires and a vacuum also discovered law of attraction repulsion tube. between magnets; ‘De Magnete’ (1600) William Morgan a British physician, Gave food for thought to Galileo who physicist and statistician, who is proposed that the ‘Earth revolves around considered the father of modern actuarial the Sun’ science. He is also credited with being the first to record the "invisible light" Robert Boyle, an Irish philosopher, produced when a current is passed through chemist and physicist discovered that a partly evacuated glass tube: "the first electric force could be transmitted through x-ray tube". a vacuum and observed attraction and 1785 repulsion. RADIOLOGY: HISTORY OF PERSPECTIVE Cabalog K.J BSRT 1-51A presented a paper to the Royal Society of London Michael Faraday was an English scientist who contributed to the study of electromagnetism and electrochemistry. Aug 29th 1831 He is credited for the discovery of electromagnetic induction.
