A hundred million years from now, when we're all dead and gone, a team of geologists will be digging in a field somewhere ...and they will discover, buried in the rocks below, a thin layer of sediment — very thin, about the width of a cigarette paper, says British stratigrapher Jan Zalasiewicz. That skinny strip, when … Continue reading Is Planet Earth Under New Management? : Krulwich Wonders… : NPR

Artificial intelligence is what we can do that computers can’t…yet

A classic experiment published in 2000 seemed to provide overwhelming evidence that a particular behavioral choice (whether individuals of a species of swallow breed in a small … Continue reading The importance of (experimental) design — ScienceDaily
Brian Greene on free will
Ignostic Atheist called my attention to this video of Brian Greene contemplating free will. Greene's take: useful to buy into but illusory. I know many readers will disagree about the 'useful' bit, while I prefer 'emergent' instead of 'illusory', but basically agree with his sentiment. http://www.youtube.com/watch?v=KBNzaXx6eKg
Searching for empirical anomalies
Ars Technica has an article about the most accurate measurement yet of the mass of the electron. It was an interesting article, particularly in describing how the scientists went about making the measurement. But I was struck by something said at the end: Physicist know that the Standard Model—great for explaining the world of the … Continue reading Searching for empirical anomalies
