How Do We Know What Time It Really Is? (Part 2)
The role of the Universe in Keeping Time
Methods of keeping track of time date back to ancient days, but it wasnt until the 19th and 20th centuries that the science behind more accurate timekeeping and how that relates to the universe around us was more understood — or at least investigated. Key players in science and mathematics also played an important role in trying to understand how time works. Prominent scientific figures such as Galileo and Dutch astronomer Christian Huygens led the understanding of time in the 16th and 17th centuries, but it was Albert Einstein, Carl Neumann, and the like who looked at absolute and mathematical time at the end of the 19th and beginning of the 20th centuries and then questioned those theories even further to try to explain the workings of modern timekeeping.
Sir Isaac Newton (1643-1727) was an English mathematician upon whose theory more investigation into time was based. Newtons law of inertia, which meant that one particle in space, not acted upon by other forces, continued to move in the same direction and would remain at the same speed, was the basis of Carl...
