For Your Consideration

From our place in the universe, to the relationship between science and art, to the very nature of knowledge itself, I have fun getting a little philosophical in these articles from my monthly column for Astronomy Magazine.

Art and Science: A False Dichotomy

Is there no beauty in truth?

During the Dutch Golden Age, did Johannes Vermeer use optical devices to capture light, detail, and perspective as never before? If he did, does that make him a fraud, or instead an altogether different kind of genius?

Intentional Ignorance

Climate change deniers are trying to make NASA conveniently blind

There are a record breaking three Category 4 hurricanes and a new tropical depression in this August 30, 2015 image of the Pacific Ocean taken with NASA’s GOES-15 satellite. We depend on our ability to observe Earth from space. So why is Congress gutting the program?

  • On a cold day in April, 2017 scientists gathered in Washington DC and cities around the world for the March for Science. Their message was a single powerful idea. Truth is not a political expediency. Reality cannot be ignored. In the year that has followed the vital importance of that message has only grown.

  • When I look at NASA’s new Administrator, Jim Bridenstine, it is his fellow Oklahoman Scott Pruitt’s EPA that jumps to mind. As politically uncomfortable science is pushed aside, NASA’s history of nonpartisanship appears headed for an abrupt end. Will a strongly partisan NASA have a target on its back?

  • Some years ago, NYU physicist Alan Sokal wondered whether anti-science postmodernists could recognize politically-correct-sounding nonsense even if he rubbed their noses in it. The unwitting subjects of the Sokal Hoax jumped at the bait.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

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