Medical laboratory technologists (commonly known as medical laboratory scientists) and medical laboratory technicians collect samples and perform tests to analyze body fluids, tissue, and other substances.owever, technologists perform more complex tests and laboratory procedures than technicians do. For example, technologists may prepare specimens and perform manual tests that are based on detailed instructions, whereas technicians perform routine tests that may be more automated.
But how fast does the Earth rotate? You might be surprised to know that a spot on the surface of the Earth is moving at 1675 km/h or 465 meters/second. Thatâs 1,040 miles/hour. Just think, for every second, youâre moving almost half a kilometer through space, and you donât even feel it.
If you divide Earth's equatorial circumference  by the 24 hours it takes to complete each rotation, you get about  1038 miles per hour or about 1670 km/h. Gravity keeps everything  from flying off into space like someone on one of those small  carousels in the park.    BTW, to get the approximate speed due to rotation of Earth's  surface where you are, multiply the speed above by the cosine of  your latitude.
