    Some people are sure they know more than the experts, but it can take a lot of knowledge to realize just how wrong an idea is.

  • Our Need to Know
    We crave certainty, even when it is only an illusion

    The human brain craves the sensation of knowing like a drug addict craves the next fix. If real knowledge is uncomfortable or not at hand, we are quite content to just make something up, then convince ourselves it’s real. In a world where knowledge matters, that’s dangerous.

  • A Saguaro’s universe
    Building a cactus starts with the Big Bang

    The iconic saguaro cactus gives the desert an otherwordly beauty. That beauty does not exist in isolation. It embodies the fascinating and awe-inspiring processes that have shaped the universe, going all the way back to the Big Bang itself.

  • Oklahoma Skies
    To all the amateurs out there, thanks!

    Looking at room full of amateur astronomers, gathered for the Okie-Tex Star Party under the spectacularly dark skies of the Oklahoma Panhandle, I am reminded of my own roots and those who helped me discover the universe.

  • Fight-or-Flight
    How our Pleistocene brains (mis)handle modern threats

    A strong fight-or-flight reaction served our evolutionary ancestors well. If the leopard catches you, that’s it! But today a visceral response to a not-so-mortal threat seldom improves things. If you want to get a handle on those intense, counterproductive bouts of emotion, start by understanding where fight-or-flight came from in the first place.

  • In a Shark’s Eye
    Science and the experience of wonder

    Alone, 100 feet underwater, with a shark in its element, I am overwhelmed by a mixture of awe, beauty, joy, and intellectual wonder at the world that brings us together. In that moment, I experience just what science is all about.

  • The Quandry of Unpredictability
    Chaos, climate and an unpredictable future

    Chaos is a sticky wicket for science. There are things a correct theory like climate change cannot predict, but there are a lot of things that it can. It’s important to understand which is which.

  • Why I March for Science

    On Earth Day, April 22, 2017, people around the nation will March for Science. It seems strange to need to march in support of the idea that pronouncements from politicians cannot change the nature of reality, or that evidence matters when making decisions. But such are the peculiar times in which we live.

  • Waiting for Skynet
    The benefits of being a machine

    For biological organisms, interstellar travel is hopelessly difficult, and probably pointless. For sentient machines, however, home is the environment you were built for.

  • Where Are They?
    Why E.T. might stay home

    It would be fun to think there is a flourishing interstellar civilization of humanoid aliens out there. But then it would also be nice to believe in unicorns and midichlorians. It would be nice, but they probably aren’t there.

  • Pulsars and Neutrinos
    The history that LIGO forgot

    Gilding the lily makes everybody look bad. When the Laser Interferometer Gravitational-Wave Observatory detected ripples in the fabric of space-time from a pair of merging black holes, it was a technological and scientific accomplishment without peer! But LIGO did not “discover” gravity waves.

  • Not The End of Science
    The emerging science of process

    Fundamental change is always messy. As science tackles the complex processes that shape the real world it is having to reinvent itself on the fly. Welcome to the Wild West!
