Assignment Overview: This discussion helps you review Chapter 1 topics about mathematics and some of the ways physics affects our world. Instruction select and discuss one of the concept questions drawn from Chapter 1 topics - this forms your initial post. The remainder of the discussion will be responses to your peer's posts as outlined in the Discussion Instructions. Concept Questions (Select One) Before we started using an atomic clock as a time standard how did scientists, from the beginning of science to pre-atomic clocks, make time measurements in their experiments/observations? Claim your method by stating it in your Subject heading and describe the method and who used it. Also discuss the importance of having a time standard in experimental research. Pick one the following early physicists, who lived between 1544 and 1960, and summarize at least one or two contributions they made to their field of study. Discuss why you think their contributions were important.
