That&#8217;s very good, and a good sign for plans to do precision spectroscopy and other such experiments. As always, <a href=\"http:\/\/physicsworld.com\/cws\/article\/news\/45912\">Physics World offers a nice write-up<\/a>.<\/p>\n<p>2) As noted in the comments of <a href=\"http:\/\/scienceblogs.com\/principles\/2011\/05\/proving_einstein_wrongish_meas.php\">Monday&#8217;s ResearchBlogging post about Brownian motion<\/a>, the same group has a <a href=\"http:\/\/www.nature.com\/nphys\/journal\/vaop\/ncurrent\/full\/nphys1953.html\">new experiment extending their previous work<\/a>. They&#8217;ve beefed up their detection system to the point where they can measure displacements in picometers, and used it to observe the jittering of a glass bead suspended in water. In this case, because the time scales involved are much shorter, they see both the &#8220;ballistic&#8221; behavior and the more traditional Brownian motion described by Einstein&#8217;s model. It&#8217;s a really nice experiment, if you have access to the paper.<\/p>\n<p>That&#8217;s science for you&#8211; just when I think I&#8217;ve written the definitive blog post on a subject, researchers go and improve their experiment by three orders of magnitude&#8230;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>It&#8217;s been a hectic day here, so I haven&#8217;t had time to do any substantive blogging.
