Neil DeGrasse Tyson

…and the science of smug condescension:

Here we see, in action, the signature scientific style of the Neil deGrasse Tyson era. Present a scientific theory in crudely oversimplified form, omitting any uncertainties or counter-arguments. Pass off complex claims as if they are obvious “basic physics.” Then dismiss any skepticism as the resentment of the primitive, ignorant, unscienced masses against their enlightened betters.

Or, you know, file law suits against critics.

It’s not a very good way to get valid scientific results—nor, for that matter, to promote the scientific method. But it’s what we get when we substitute, in place of respect for the actual methodology of science, an attitude of superior posing and smug condescension.

I’d like to say that I was disappointed with the Cosmos reboot, but honestly, I wasn’t that big a fan of the original. But I’d love to buy Tyson for what I think he’s worth, and sell him for what he does.

[Afternoon update]

Some more thoughts:

It seems to me that Neal deGrasse Tyson is a scientist. Heck, I don’t actually know, because I don’t read technical astronomy papers, but I assume he’s published something somewhere, actually done some science in his life. But that doesn’t appear to be his current day job. His current job, near as I can tell, is carnival barker. He’s a salesman, or an advertiser. That’s not science. Inspiring others to want to learn more may be laudable, but it’s not science. Making crap up isn’t science, either, but I’ll let the serial stalkers at the Federalist worry about that.

But here’s a misconception that I’ve discussed before:

Thing is, I’m no scientist. So while I would like to call myself a Science-ist – that is, one who believes in the nature of science and the good results it can produce – I certainly can’t pretend I am a scientist, which is one who does science. Stuff like collecting data, analyzing it, proposing hypotheses, testing hypotheses. You know, stuff that scientists do. Not just looking at cool pictures of galaxies and pretending that makes me smart. (Um, NSFW language at that link)

No. Science isn’t a profession, it’s a way of thinking about the world, and learning about it. Everyone does it, to some degree or another, every day. Check a door knob to see if it’s unlocked? You just did an experiment.

People who believe in “science” as some kind of special realm that “scientists” live in, and that “science” reveals “truth” (as many global warm mongers do, even though they don’t understand the science or, often, even basic math) are members of a religion, that is in fact properly called scienceism. I believe in science as the best means to learn about the natural world, and as the basis for engineering and creating technology, but I don’t worship scientists, and I don’t delude myself that scientific results are “truth.”

Anyway, finally, note this comment:

you make an ass out of neal tyson when it’s pointed out that he has not, in fact, published A SINGLE PIECE of academic work since having talked some committee into accepting the dissertation it took him 11 years (and an expulsion!) to co-author.

no, seriously. if you don’t believe me, you can put his name into the search bar at arxiv.org, where practicing physicists post our preprints:

“Search gave no matches

No matches were found for your search: all:(neal AND tyson)

Please try again.”

In the next comment, he notes that there is in fact one post-doc paper, but it appears that he’s just participating because the actual authors wanted a bigger name on it.

The SLS Frenzy

So apparently, the SLF fanbois (and fangirls) going crazy over a giant welder on Twitter.

Anyway, I was rereading this essay I wrote half a decade ago. It was depressing. Here’s how little of some of it I’d have to change to keep it relevant to today.

KSC Versus MSFC

I had an interesting Twitter discussion this morning, that gave me an insight that had been floating around in the back of my mind, but that I’d never articulated, either to myself or others. It sort of crystallized when someone said that Bob Cabana, head of KSC, was an SLS supporter.

One of the tenets of the Apollo Cargo Cult is that we can’t go beyond earth orbit without a really big rocket. The conventional wisdom has been that the biggest constituency for SLS is Marshall, because that’s were it is being developed. But if you think about it, there are a lot of things Marshall could be applied to — it doesn’t have to be developing big rockets (something it hasn’t successfully done in almost four decades). For instance, it could be developing technology and demonstrators for orbital fuel storage and transfer. That would be at least as much in its wheelhouse as SLS.

KSC, on the other hand, has little justification for existence if NASA doesn’t have its own (big) rocket to launch. Without a big rocket, it doesn’t need the VAB, and the VAB and the crawler are really the only unique capability it has, in terms of physical infrastructure. If everything is going up on commercial rockers, even from Pads 39, KSC doesn’t have much to do, other than integrating NASA’s payloads onto them. That’s not a trivial task, but it’s not one that justifies the center’s budget or workforce. So, while Marshall could in theory be redirected to something useful, KSC can’t really. That’s why Nelson supports it so strongly.

It struck me in fact that the VAB is the high cathedral for the cargo cult. What would happen to the religion if it was taken out by a hurricane?

The Hubble Group

So the big news today is that they’ve named the supercluster we live in:

Scientists previously placed the Milky Way in the Virgo Supercluster, but under Tully and colleagues’ definition, this region becomes just an appendage of the much larger Laniakea, which is 160 million parsecs (520 million light years) across and contains the mass of 100 million billion Suns.

Which kicked off this Twitter exchange between me and Lee Billings.

Accordingly, I propose that we rename the Local Group the Hubble Group, in honor of its namer, and making it consistent with the other names. I will henceforth call it that. If anyone asks, I’ll explain.

The Apollo 11 Moon Landing

Some reflections from Bill Whittle.

[Monday-morning update]

It’s long past time to rethink NASA:

Unrealistically, the NRC committee recommends a 5 percent annual increase in NASA’s budget to carry out its recommendations, which are to spend billions for many decades with the eventual result of putting a few civil servants on Mars. My assessment, as a space enthusiast and a taxpayer? As Senator William Proxmire once famously quipped, on the topic of funding for space colonies: “I say not a penny for this nutty fantasy.” I don’t know what the future of human spaceflight is, but I do know that the NRC’s recommendations are not it.

Read the whole thing. It was written by someone who knows what he’s talking about, one of the great minds of our age.

[Update a couple minutes later]

Some of the comments over there are amusing, albeit predictable.

[Update a few minutes later]

Should we go back to the moon? I participate in a debate on the topic, over at US News. I have to say that Etzioni’s remarks are certainly ignorant. And you’ll be shocked to discover that Bob Zubrin wants to go to Mars.

[Update mid morning]

I have a roundup of my and others’ apollo anniversary pieces over at Ricochet. Plus, hey moon! We’re coming back soon.

[Late-afternoon update]

I’m tied with Peter over there for thumbs up, if you want to go vote. Also, Bob is getting lots of negative ratings, but nothing like Etzioni.

[Bumped]

[Late evening update]

I assume that, thanks to my readers, I’m Number One!

Why NASA Is Stagnant

Thoughts from Bob Zubrin. I haven’t read yet, but I’ll have some of my own over there tomorrow, I think.

[Update a few minutes later]

OK, I read it. I disagree with his diagnosis of the problem, but I absolutely agree that we need to have a serious national discussion of why we have a government-funded human spaceflight program. That hasn’t happened in half a century. Until we do, we’ll continue to flounder, and be hostage to the whims of the rent seekers in Congress.
