In this article, I will also grapple with the fascinating question of “where do ideas come from?” Since I was a student, I have always wondered how ideas came about. ![]() When I enquired as to how these two areas “got lost,” I was told that there wasn’t room for them-despite the glaringly empty space following the last (important but rather arbitrary) entry, Education.Įmbellished Pastorale in F (Johann Sebastian Bach). As you can see, neither gravitational physics nor precision measurement made the list of “ALL” areas of physics. In March of 1999, when the American Physical Society had its centennial celebration, it provided a viewgraph (for the use of a group of centennial speakers-I was one) that was entitled “Throughout the Year we are Celebrating ALL (capitalization theirs) Areas of Physics” ( Fig. In spite of the importance of this field to scientific progress, precision measurement science is often overlooked. The reason is that this area of physics is not just a collection of accurate measurements rather it is an area of fundamental importance that involves measurement science applied to a broad range of related experiments and therefore no “s.” I also want to reflect on precision measurement-not, the reader needs to understand, precision measurements-by using these various measurements as examples of experiments of this type. The final measurement in this group of related experiments was a test of the inverse-square law of gravitation on the scale of meters to kilometers. ![]() The other equivalence test that I will mention was a result of the lunar laser-ranging experiment. One experiment that I will describe tested the equivalence of free fall for different masses in response to local attracting matter (the Earth) rather than to more distant matter (the Sun, which has been used in recent equivalence tests). ![]() Reprinted by permission of Universal Press Syndicate. ![]()
