The Revival of Science:17th and 18th Centuries Galileo Discovers: Gravitational acceleration- velocity a body achieves while falling, is independent of weight Earth moves around the sun Torricelli and Pascal Discovers: hydrostatics and dynamics develop the barometer Boyle Discovers: expansion quality of air and the correlation between temperature, volume, and pressure

44. The Revival of Science:17th and 18th Centuries Hooke Discovers: material lengthens in proportion to the force exerted on it, up to the elastic limit, and in compression it shortens in a similar fashion Huygens develops spiral watch spring and the pendulum clock and measures gravitational acceleration Newton who is famous for his three basic laws of motion developed differential calculus, essential to mathematical analysis of most physical systems

It weighted over 30 tons and occupied over 1500 square feet. John Bardeen, Walter Brattain, and William Shockley, at Bell labs, discovered that current changes in one part of a diode caused current changes in another part of a diode and create the transistor.

49. 20th Century Technology Texas Instruments and Fairchild Semiconductor discovers that the transistor’s silicon crystal could be made to be its own circuit board. “transistors - the switch that controls the world” Pratt & Whitney develop turbojet engines Boeing Airplane Company develop the Boeing 707 capable of transporting 180 passangers at speeds of 600 mph Theodore Maiman produces the first working laser which has mushroomed to encompass surgeons, transmit telephone calls, track storms, to checkout in supermarkets, to weld steel, to cut fabric and to produce holograms
