Joseph Priestley is best known as the discoverer of oxygen.\nHe isolated 'depholgisticated 'air, or 'good air' in 1774. Our understanding today of the chemical reaction of oxygen comes from Antoine Lavoisier's systematic theory of combustion.\n\nToo bad contributors like the above 'opinion' can't use this forum as a means of increasing knowledge, rather than \ngiving silly answers in order to get points. Some never grow up i suppose.\nSource:www.woodrow.org./teachers/chemistry/institutes/priestley.

The first reasonably accurate mechanical clocks measured time with weighted pendulums, which are useless at sea or in watches. The invention of a spring mechanism was crucial for portable clocks. In Tudor England, the development of "pocket-clockes" was enabled through the development of reliable springs and escapement mechanisms, which allowed clockmakers to compress a timekeeping device into a small, portable compartment. In 1524, Peter Henlein created the first pocket watch. It is rumoured that Henry VIII (the portrait of Henry VIII at this link shows the medallion thought to be the back of his watch) had a pocket clock which he kept on a chain around his neck. However, these watches only had an hour hand - a minute hand would have been useless considering the inaccuracy of the watch mechanism. Eventually, miniaturization of these spring-based designs allowed for accurate portable timepieces which worked well even at sea. Aaron Lufkin Dennison founded Waltham Watch Company in 1850, which was the pioneer of the industrial manufacturing by interchangeable parts, the American System of Watch Manufacturing.

Thomas Alva Edison invented the light bulb, the phonograph, automatic telegraph, motograph, paraffin paper(which was used to wrap candy), electric pen, carbon rheostat, microtasimeter, sockets, switches, insulating tape, gummed paper tape, magnetic ore separator, life-sized electric railway, motion picture camera, steel alkaline storage battery, and many other things.  He had 1,368 different patents.

"A better battery? A better mousetrap." \n\n"Every laptop and cell phone owner I know wants more battery time.  If it works as advertised, we'll soon see laptops with 10 hour batteries."\n\n"Saphion technology is superior because Saphion technology possesses safety and excellent cost/performance characteristics that cathode materials currently used in Lithium-ion batteries do not."

Inventor of Luminol\n\nIn 1895, two scientists named Wiedemann and Schmid, dissolved cathode-ray irriaded alkali halides such as NaCl, NaBr, KCl, and KBr, in water.  They noticed a very weak bluish light.  They also detected light production when irriaded calcium carbonate was “attacked” by aqueous hydrochloracetic acid, or phosphoric acid4.\n\nLater in 1928, a chemist by the name of Albrecht discovered a specific chemical, that when placed in an aqueous alkaline solution emitted a blue-green light with a fair amount of intensity.  Along with the light, virtually no heat was produced.  This solution contained hydrogen peroxide along with a catalyst.  The catalyst was an alkaline medium with a pH between ten and eleven.  This specific chemical was to later on be called luminol.

Read the link below\n\nJames Prescott Joule\n\n(born Dec. 24, 1818, Salford, Lancashire, Eng.-died Oct. 11, 1889, Sale, Cheshire) English physicist. After studying under John Dalton, in 1840 he described “Joule's law,” which stated that the heat produced in a wire by an electric current is proportional to the product of the resistance of the wire and the square of the current. In 1843 he published his value for the amount of work required to produce a unit of heat, called the mechanical equivalent of heat, and established that heat is a form of energy. He established that the various forms of energy are basically the same and can be changed from one into another, a discovery that formed the basis of the law of conservation of energy, the first law of thermodynamics. In his honour, the value of the mechanical equivalent of heat is usually represented by the letter J, and a standard unit of work is called the joule.
