The Eclipse In Southern California

10 Comments

Would have liked to see totality (guess it remains on the bucket list, maybe 2024 or somewhere else sooner), but we got about sixty percent coverage here. There was a thick marine layer when we awoke, but the clouds broke up in time for us to watch the whole thing. As I saw the moon slice along the left side of the sun, it was easy to imagine it projecting the full shadow a thousand miles north. I took a picture of a natural pinhole camera with hundreds of crescents in our driveway.

A few of my eclipse jokes on Twitter:

…has reviewed Nina Teichholz’s book:

Many readers will be incensed by this book. If you think saturated fats and cholesterol are bad for you, you’ll be incensed. If you think the fat story is exaggerated, you’ll be incensed. If you trust in the objectivity of science to inform health policy, you’ll be incensed. Stories of shocking scientific corruption and culpability by government agencies are all to be found in Nina Teicholz’s bestseller The Big Fat Surprise. This is a disquieting book about scientific incompetence, evangelical ambition, and ruthless silencing of dissent that has shaped our lives for decades.

Good for her.

…feel weird.

I wonder if the breaking down in tears is a current phenomenon, or if it’s traditional from when most people didn’t know what was going on, and thought it was the end times?

I disagree with this, though:

…for an eclipse with specific properties (such as total versus partial, long versus short, and tropical versus arctic) to make a repeat appearance in any particular region, one has to wait while eclipses work their way around the world like a set of gears, which requires three Saroses—a length of time equal to fifty-four years and around one month, or, more precisely, thirty-three days. Because this surpasses human life expectancy in that era four thousand years ago, it’s astonishing that the cycle was noticed at all.

Only if you don’t understand that life expectancy is an average, with a high standard deviation. Many, and particularly ancient astronomers, would have likely lived much longer than average.

We were in Denver over the weekend, and went up to Wondervu Saturday might for a meeting of the Sky Watchers club (invited by Leonard and Barbara David, who have a place up there in the mountains above Boulder). One of the lecturers (retired from the National Renewable Energy Lab in Golden) gave a talk on NREL’s analysis of probability of not having clouds along the entire path. He had seen the one in Aruba in the ’90s, and he and most of the people there planned to go up to Casper to see it. I’d like to, but I can’t justify time/money right now.

…”scientists” zero:

…in a sense, the video doesn’t even refute the straw man it set up. It’s not that climate science consists only of models: obviously there are observations too. But all the attribution claims about the climatic effects of greenhouse gases are based on models. If the scientists being interviewed had any evidence otherwise, they didn’t present any.

When you can’t even knock down your own straw man, you don’t have much of an argument.

So how did the video do refuting Scott Adams’ cartoon? He joked that scientists warning of catastrophe invoke the authority of observational data when they are really making claims based on models. Check. He joked that they ignore on a post hoc basis the models that don’t look right to them. Check. He joked that their views presuppose the validity of models that reasonable people could doubt. Check. And he joked that to question any of this will lead to derision and the accusation of being a science denier. Check. In other words, the Yale video sought to rebut Adams’ cartoon and ended up being a documentary version of it.

They would appear to lack self awareness.
