This sort of cuts down on my ability to think Deep Thoughts and post the results here.<\/p>\n<p><P>I can, however, carry out mechanical tasks like tallying the nominations for the <A HREF=\"http:\/\/scienceblogs.com\/principles\/2006\/01\/greatest_experiment_ever.php\">Greatest Physics Experiment<\/A> (to go with Clifford&#8217;s <A HREF=\"http:\/\/cosmicvariance.com\/2006\/01\/16\/the-greatest-physics-paper-the-result\/\">Greatest Physics Paper<\/A> on the theory side). The list of experiments mentioned by at least two different people in the comments comes to eleven, listed here in order of age:<br \/>\n<UL><br \/>\n<LI>Galileo Galilei: ~1610: Discovery of the moons of Jupiter, and measurements of the acceleration of falling objects.<br \/>\n<LI>Ole Roemer ~1675: Measurement of the speed of light by timing the eclipses of Io.<br \/>\n<LI>Isaac Newton ~1700: Dispersion of light and measurements of circulating fluids.<br \/>\n<LI>Henry Cavendish, ~1797: Measurement of the graviational constant G.<br \/>\n<LI>Michael Faraday ~1831: Discovery of electromagnetic induction.<br \/>\n<LI>Michelson and Morley ~1887: Disproving the existence of the luminiferous aether.<br \/>\n<LI>Heinrich Hertz ~1888: Creation and detection of electromagnetic waves.<br \/>\n<LI>Ernest Rutherford ~1909: Discovery of the nucleus of the atom.<br \/>\n<LI>Edwin Hubble ~1929: Determination of the distance to galaxies, and measurement of the expansion of the universe.<br \/>\n<LI>Rudolf Mossbauer ~1957: Discovery of the Mossbauer Effect and gamma-ray spectroscopy.<br \/>\n<LI>Alain Aspect ~1981: Experimental tests of Bell&#8217;s Inequality.<br \/>\n<\/UL><\/p>\n<p><P>(Dates are pulled off Wikipedia, and hence highly approximate. In some cases, I&#8217;ve lumped together votes for two different experiments by the same person in order to draw up the list. Newton just barely squeaks on by this method, but he&#8217;s such a prickly bastard that it wouldn&#8217;t be wise to leave him off&#8230;)<\/p>\n<p><P>It&#8217;s a pretty impressive list, really, spanning four centuries and a great many important and historic experiments. The list of people left out (go look at the comments to the other thread) is just as impressive.<\/p>\n<p><P>So, here&#8217;s the plan. Over the next indeterminate period of time, I will endeavor to write up short pieces describing the various experiments and observations on the list, and where they fit in the history of modern physics. After that, if I haven&#8217;t lost interest, I may put it up for another vote, which I promise will be every bit as scientific as the last one.<\/p>\n<p><P>If you&#8217;d like to complain about voting irregularities, or castigate me for leaving out your personal favorite experiment, well, you know where the comments are.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Evil elves have apparently snuck into the house in the middle of the night, and stuffed my sinuses with cotton and motor oil (the dog is sitting here muttering &#8220;I told you there were evil elves out there but did you listen? &#8216;Stop barking at nothing,&#8217; you said&#8230;&#8221; Or maybe that&#8217;s the drugs.).
