Wow

I decided to pull this up into a separate post, because I think it illustrates exactly the problem that Frank Tipler was identifying. Two comments:

“I’ll add that General Relativity is sort of a “dead end” in physics in the sense that practically nothing depends on it. You can’t really use it for anything.

and

Rand, I think you just cited the exception that proves the rule when you referenced GPS. Where else do you use general relativity on a regular basis? It’s an interesting topic, but doesn’t seem to be core to a physics degree.

Well, I provided at least one more example–tracking NEOs that might hit us in the next few decades.

But the point is that if you don’t understand general relativity, you won’t even know whether or not you need to consider it. I’m simply staggered by the notion that it’s an esoteric field that has no use.

Any time you do an orbital calculation, you have to know whether or not you can get by with Newton, or whether or not you need to incorporate Einstein. It may be that in many cases you don’t need to, but to not even consider it would be professional malpractice, just as someone doing a suborbital rocket would need to decide whether a flat-earth (i.e, Galileo) model was good enough, or if they had to do it Newtonian, and consider the differences in the model. And how could you possibly make such an assessment if you don’t understand General Relativity?

To me, this simply reinforces Tipler’s point.

Whose Ox Is Being Gored?

Literally, in this case, given the name of the high priest.

I wish I’d thought of this:

I keep reading about how hybrid cars and compact fluorescent lightbulbs can reduce the production of greenhouse gases, but I have yet to see an article about the savings that could be achieved if we were to stop delivery of newspapers and magazines and do all of our news reading on line.

Hey, I think it could rival toilet paper usage reduction as a solution to the problem. Maybe even beat it.

Hey, now I’m thinking dual-use here. I’m a genius (no need for applause in comments, but you know you want to…). It’s not just for training puppies and parakeets any more!

Darwinism Debate

Andrew Ferguson has a report on the debate that I asked about last week, that (sort of) answers my question. And I see that Derbyshire had the same question:

Darwinism, viewed one way, can easily be considered morally disastrous. But, responded pro-Darwin Derbyshire, Is it true? “The truth value of Darwinism is essential,” he said. “The truth value always comes first.” If Darwinism is true–and its undeniable success in explaining the world suggests that it is–and if Darwinism undermines conservatism, as West had claimed, “then so much the worse for conservatism.”

I’d like to think that he was influenced by the email I sent him with a link to my post before the debate, but I suspect that he was already loaded for that particular bear. And I agree with Gilder, despite his disbelief:

“Darwinism may be true,” he said, “but it’s ultimately trivial.” It is not a “fundamental explanation for creation or the universe.” Evolution and natural selection may explain why organic life presents to us its marvelous exfoliation. Yet Darwinism leaves untouched the crucial mysteries–who we are, why we are here, how we are to behave toward one another, and how we should fix the alternative minimum tax. And these are questions, except the last one, that lie beyond the expertise of any panel at any think tank, even AEI.

It is possible to try to build an ethical system out of evolutionary theory, I suppose, but it’s certainly not necessary, and not necessarily desirable.

[Afternoon update]

Derbyshire cites my previous post, and has further thoughts.

A New Wrench In The Works

for climate models? And Warmmongers like Gore?

Precisely accounting for everything in the atmosphere that can influence changes in global temperatures is critical to scientists’ quest to accurately predict what Earth’s climate will be in the future. The latest report from the Intergovernmental Panel on Climate Change, which assessed the potential risks of human-induced climate change, notes that the overall effect of clouds and aerosols on the amount of heat held in the atmosphere is still uncertain. Finding a previously unknown ingredient in the mix further complicates an already complex picture, but it also holds out the promise of resolving some nagging problems in climate change science.
