NMT to disinvite Harrison Schmitt?

I posted the following to an alumni group’s Facebook page in response to a post that cited this article and invited alumni to ask the school’s president to disinvite Schmitt.

I have difficulty believing there is a serious movement to disinvite Dr. Harrison Schmidt as commencement speaker. He’s an astronaut who’s explored — as a trained geologist — another planet, on foot. If he’s wrong about climate science, well, he won’t be the first person to demonstrate the Dunning Kruger effect. I’m think in particular of a physics professor who was determined to bring back punched card media for his simulation software.

But more than that, I am appalled that the professors at Tech are failing to teach their students that Science is not a collection of orthodoxies that must not be questioned. When I went to Tech, I heard from my petroleum engineering friends that one of the geology faculty refused to subscribe to the theory of plate tectonics. I don’t know if that was true, but it was believable because people were allowed to hold unpopular opinions. When I was at Tech, we read “The Structure of Scientific Revolutions” and learned the big problem in science is overcoming the informal orthodoxies that creep in despite our best intentions. We watched Carl Sagan’s “Cosmos” and shook our heads at the medieval clergy who treated Galileo as a heretic and refused to look through his telescope.

But worst, I think, is the boorish gauchery of disinviting a speaker from an event after the invitation had been made and accepted. What kind of people would even consider it? A few years ago, I thought President Trump was 50% vulgarian, 50% clown, and 100% reality show personality. Today, I’m afraid he embodies the spirit of our age. The idea that Techies would outdo him in classlessness… it’s #Sad.

Phobos not a captured asteroid?

New research suggests that Phobos, the larger of Mars’ two moons, isn’t a captured asteroid after all. It’s still not clear if it was ejected from Mars in some kind of impact, or if it’s all that’s left after an earlier moon broke apart and augured in.
