Certainty Principles in Physics

Near-perfect physics. ‘Using better instruments and more powerful computers, scientists are demonstrating key aspects of physics with unprecedented precision. Three weeks ago, an international team showed how observations of an unusual double star system verify an effect predicted by Einstein’s general relativity to an accuracy of 99.95 percent. That leaves little wiggle room for doubts […]

About Science Blogs

If Einstein were a blogger…: At first glance, the wild, wooly world of blogs and the sober, serious world of science shouldn’t mix. After all, blogs — or personal Web logs — are all about opinions and attitude, with logic playing second fiddle to outrage. Turns out, however, that science and attitude combine quite well. […]
