“Exploring the Role of Time Standards and Notable Contributions in Physics”

This discussion helps you review Chapter 1 topics about mathematics and some of the ways physics affects our world.
Instructions
For this discussion, you must 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.
Find a recent discovery that has to do with physics from these sites:
Science Daily
Scientific American
Physics World
Briefly tell us: who the primary investigator is and what they are researching or found. Make sure to provide a hotlink to your site and proper citation.
Before you post please look through all Subject lines. If there have already been 3 posts on one question, please pick from the other questions so that all questions are selected evenly. Only after all questions have been selected with 3 posts should you start to repeat questions.
Make sure your Subject line very briefly notes the question you’ve selected and include a few words that tells your classmates what makes your post unique, trying to keep your Subject line under 6-7 words.
