The fluid straightened the dog’s hair so a great deal that its operator supposedly unsuccessful to identify it afterward.

Arithmetic led Gladys West from the Virginia farm of her childhood 100 miles north to a United States naval facility, where she did sophisticated calculations and programmed personal computers for four a long time right up until her retirement in 1998. She led groups on groundbreaking satellite projects checking the world’s oceans and producing a comprehensive product of Earth’s area, a branch of science named geodesy (gee-ODD-es-see). Her function grew to become the basis for the Worldwide Positioning Procedure (GPS). Satellite-dependent mapping methods are used all over the world, but not by West. She prefers paper maps.
