Gun Control

18 Comments

A statistician changes her mind after actually looking at the data:

“A reduction in gun deaths is most likely to come from finding smaller chances for victories and expanding those solutions as much as possible,” Libresco concludes. “We save lives by focusing on a range of tactics to protect the different kinds of potential victims and reforming potential killers, not from sweeping bans focused on the guns themselves.”

Libresco says she still does not endorse gun ownership, “but I can’t endorse policies whose only selling point is that gun owners hate them.”

What a concept.

Dissing Virgin Galactic

You can find a NASA astronaut to come up with any opinion you want, but Andy Thomas isn’t impressed with SpaceShipTwo. I share the criticisms (which were made by me and others when the SpaceShipOne concept was first revealed), but I don’t think it’s doomed to failure. It offers a different experience than New Shepard, and will have its own market. I continue to find it ironic that the systems Burt added for “safety” probably added hazards instead.

Nadia Drake has the latest. We continue to not have a gravity lab to study this.

[Update after reading the whole thing]

They seem to be proposing a gravity lab (still unfunded), but they want to put it in lunar orbit. I see no reason to do this, other than to give the Gateway something to do; LEO (and probably in the ISS orbit) makes a lot more sense to me.

Good Food Advice

…for the wrong reasons:

Breads made with white flour have not only been stripped of all of their nutrients, but they might even contain remnants of the chemical used in the bleaching process. Our obsession with white foods (sugar, I’m looking at you) is totally odd and unfounded. The natural, unbleached version tastes the same (if not better) and is far more nutritious.

Not really. You should cut out the bread, period.

Why must everything that tastes so good be so bad for us? Our beloved creamy, fulfilling ice cream is extremely high in sugar and fat. And since milk is an animal protein, it’s also high in cholesterol. Sure, you can opt for some yogurt or a vegan dessert, but they’re not the same.

The problem with ice cream is the sugar, not the fat or cholesterol.

There is nothing wrong with ordering a regular cup of coffee (and you can even toss in a little half and half if you need it), but the calories add up very quickly when it comes to those fancy $7 coffee beverages. They taste so good because of all the added sugar and fat. You’ll get an immediate boost from a huge sugar rush, and then you’ll crash hard. Then you need another high-calorie coffee drink to feel better.

Again, it’s the sugar, not the fat or the calories that’s the problem here. Counting calories is junk science.

Bacon, sausage, and even cold cuts: they’re oh-so-yummy, but they’re just awful for your health. They contain high levels of unsaturated fat and sodium.

No, bacon has saturated fat. Which is good. And there is more danger from underconsumption of sodium than over.

A guaranteed way to add inches to your waist is to indulge in fried food. High in calories, fat, saturated fat, and carcinogens (yup, in those beloved french fries), there is nothing good about this. Except for their scrumptious flavor, obviously.

The problem with fried foods is not the fat, saturated fat, or calories (unless you’re frying it in seed oils, in which case the fat is bad because of the omega 6s). The problem with fried foods is carbohydrates in the batter. Deep frying dusted veggies in lard or tallow is fine.

An interesting space-related profile from Princeton, his alma mater.

I did an interview a few months ago for the upcoming documentary, even though I didn’t really know O’Neill (I met him once). He had a large indirect influence on my life. The last question I was asked was what single word came to mind when I thought about him. My answer: “Hope.”

[Afternoon update]

It’s important to understand that The High Frontier came out in the mid-70s, a time of doom and gloom. Paul Ehrlich and the Club of Rome were always banging on about overpopulation and running out of resources, and instead of global warming, we were supposed to be worried about a return of the glaciers. In addition to O’Neill’s book, Peter Vajk (himself inspired by O’Neill) came out with a book meant to be a palliative, titled Doomsday Has Been Canceled. Anyway, that’s the context in which I said that he brought hope.

Would it be a tragedy?

Note that he doesn’t consider the possibility of homes for both humanity and other terrestrial life off planet.

FWIW, if I had to choose between saving a few lives and all of the art in the Louvre, it’s not at all obvious that the lives have higher value. I can certainly imagine some people willing to sacrifice themselves for it, but that issue isn’t in his question.
