It was a challenge to hang a bird feed that they couldn’t get at. I did it by building a platform above it that they couldn’t get below.
We Are All Overconfident Idiots

…with an “undercurrent of cheesiness.” It looks like, as with Gravity, it will be beautifully annoying.
Interstellar
[Tuesday-morning update]
Christopher Nolan’s epic new sci-fi film Interstellar has received measured acclaim from critics, who have praised its ambitious scale and effects but were less convinced about the story.
That was the problem with Gravity, too.

Bias In Academia
…is destroying scientific integrity:
OK, it’s not exactly a “Sopranos” plot. But it’s pretty shady for the world of higher education. Chen went to great lengths to make up fake email addresses and even assume the names of other scientists to write approvingly of his own research.
In a sense, though, he was just exploiting the deep flaws of the peer review system. The academy has become a kind of club where friends give friends flattering assessments of research, which essentially guarantees promotions and tenure.
Here’s how the former editor of the British Medical Journal explained peer review:
“The editor looks at the title of the paper and sends it to two friends whom the editor thinks know something about the subject. If both advise publication the editor sends it to the printers. If both advise against publication the editor rejects the paper. If the reviewers disagree the editor sends it to a third reviewer and does whatever he or she advises. This … is little better than tossing a coin.”
But it’s not just the clubbiness of academia that is to blame. There is such ideological uniformity in the ivory tower that no one ever questions the important assumptions behind anyone else’s research.
Gee, where have we seen that sort of thing before?
I’d note, though, that contra the headline, it’s not a “liberal” bias. It’s a leftist bias.
Babying Mars
Is it time to stop worrying about contaminating it?
As I’ve often said, wannabe Mars colonists’ biggest fear should be the discovery of indigenous life there.

The “97%” Nonsensus
As I noted on Twitter:
Anyone who continues to push "97%" nonsense is either pig ignorant or a lying demagogue. No other options. http://t.co/BVKTYuC3Tw

Judith Curry explains:
I think we need to declare the idea of a 97% consensus among climate scientists on the issue of climate change attribution to be dead. Verheggen’s 82-90% number is more defensible, but I’ve argued that this analysis needs to be refined.
Climate science needs to be evaluated by people outside the climate community, and this is one reason why I found Kahan’s analysis to be interesting of people who scored high on the science intelligence test. And why the perspectives of scientists and engineers from other fields are important.
As I’ve argued in my paper No consensus on consensus, a manufactured consensus serves no scientific purpose and can in fact torque the science in unfortunate ways.
And José Duarte is appropriately brutal:
