What is Electronics? is the branch of science that deals with the study of flow and control of electrons and the study of their behavior and effects in vacuum, gasses, semiconductors and with devices using such electrons. This controls of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate and exploit electrons. Electronics actual history began with the invention of vacuum diode by J.A. Fleming, ( John Ambrose Fleming) in 1897. Lee De Forest implemented vacuum triode to amplify electrical signals. This led to the introduction of tetrode and pentode tubes that dominated the world until the World War II. Samuel Finley Breese Morse (1791-1872) Joseph Henry (1799-1878) Heinrich F.E. Lenz (1804-1865) Brought a telegraphy system to He independently He states that the induced the forefront with electromagnets discovered electromagnetic current’s electrodynamics & invented the code in 1844 and induction in the year 1831 – action equally resists the named after him. a year before faraday’s mechanical inducing action. discovery.  James C lerk Maxwell (1831-1879) Sir William C rookes (1832-1919) Heinrich Rudolph Hertz He developed the electromagnetic He developed electrical (1857-1894) field equations in the year 1864. discharges using “Crookes tubes” He was the first scientist to And formulated an important which are highly evacuated in demonstrate the radio theory – that is, electromagnetic 1878. waves’ existence theory of light.  AndreMarie Ampere Wilhelm Eduard Weber (1804- Thomas Alva Edison (1847- (1775-1836) 1891) 1932) He studied the effects of electric He investigated terrestrial He developed many devices current and invented solenoid. The magnetism with his friend like, practical electric bulbs, SI unit of electric current (the Karl friedrich. He devised an motion picture cameras, Ampere) was named after him. electromagnetic telegraph photographs, and other such in the year 1833 things.  Nikola Tesla (1856- Gustav Robert Kirchhoff (1824- James Prescott Joule (1818- 1943) 1887) 1889) He invented the Tesla coil. The He developed Kirchhoff’s law He discovered the law of Tesla coil was invented and used in that allows calculation of the conservation of energy. electronic equipment, television, voltages, currents, and and radio sets. resistances of electrical networks.  Albert Einstein (1879- Walter Schottky (1886- Edwin Howard Armstrong 1955) 1997) (1890-1954) Einstein employed the quantum He defined shot noise- He invented electronic hypothesis of Planck to explain random electron noise in oscillator and regenerative observable electromagnetic thermionic tubes and feedback. In 1917, he invented radiation, otherwise light invented the multiple grid the super heterodyne radio and vacuum tube. patented the FM radio in the year 1933. Jack St. Clair Kilby (1923-2005) Robert Norton Noyce (1927-1990) Seymour C ray (1925-1996) Invented the IC (integrated circuit) Implemented the IC using a The father of at Texas instruments practical approach for scaling supercomputers namely the circuit size. Seymour Cray & George Amdahl was defined as the industry of supercomputers.  Ray Prasad (1946-Still Going 2019) He initiated SMT (Surface Mount Technology) into airplanes as well as security systems at Boeing. A SMT is an area of electronic assembly used to mount electronic components to the surface of the printed circuit board (PCB) as oppose to inserting components through holes as with conventional assembly
