There have been several city-killer-class impacts since 2001. We were just lucky they didn’t hit cities. And Chelyabinsk really dodged a bullet last year. You should support the B612 Foundation. Don’t expect the government to do anything about this.

Vegetarians
…are less healthy than meat eaters.
Not surprising — evolutionarily, we’re omnivores. Vegetarians have to rationalize that they’re eating healthier to justify their unwillingness to eat animals, but they’re not.
High-School Physics
Regrets about sleeping through it.
A California Earthquake
Are we overdue?
There is a lot of energy stored in the southern San Andreas, but I don’t worry about that one, as much, because it’s sixty miles away at its closest. I’m much more concerned about a seven on the Newport-Inglewood fault, which runs just few miles from our house.
Cosmos
Chad Orzell has some problems with the reboot. So do I and while it’s not his main concern, he puts his finger on it:
The bit where he called out young-Earth creationism for the impoverished scale of its vision was cute, too, though I’m not sure it was all that necessary or useful (in that the people who believe that won’t be watching, and wouldn’t be convinced), but then the show has clearly established a pattern of throwing red meat to the anti-religious from time to time.
Yes, if by “from time to time” he means every episode so far. I’m not traditionally religious, but I find it gratuitous and off putting. The writers and Tyson seem to get some sort of righteous satisfaction from putting a rhetorical thumb in the eyes of believers. It does not advance science, or their own secular religious cause.
Oculus Rift
Is the device sexist?
Saturated Fat
The science is (finally) settled:
Since the 1970s almost everyone in this country has been subjected to a barrage of propaganda about saturated fat. It was bad for you; it would kill you. Never mind that much of the nonsaturated fat was in the form of trans fats, now demonstrated to be harmful. Never mind that many polyunsaturated fats are chemically extracted oils that may also, in the long run, be shown to be problematic.
Never mind, too, that the industry’s idea of “low fat” became the emblematic SnackWell’s and other highly processed “low-fat” carbs (a substitution that is probably the single most important factor in our overweight/obesity problem), as well as reduced fat and even fat-free dairy, on which it made billions of dollars. (How you could produce fat-free “sour cream” is something worth contemplating.)
But let’s not cry over the chicharrones or even nicely buttered toast we passed up. And let’s not think about the literally millions of people who are repelled by fat, not because it doesn’t taste good (any chef will tell you that “fat is flavor”) but because they have been brainwashed.
And this junk-science nutritional advice almost certainly contributed to my father’s death thirty-five years ago. I hope, at some point, that they stop putting all the “fat free” labels in the candy section.
The Physics Of Roller Coasters
This article appears to have the physics right, but the spelling isn’t so great. No, the car doesn’t “loose” speed.
Norman Borlaug
He probably saved more lives than anyone in history. And he understood how anti-human and anti-poor modern environmentalism is.
The American Physical Society
Just as the AAAS seems to be going all ass hat, the APS is rethinking its position on the “consensus.” Mann’s, Romm’s et al heads must have exploded when they saw that Curry, Lindzen and Christie are half of the working committee.
