…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:
The Hubble Group
So the big news today is that they’ve named the supercluster we live in:
Scientists previously placed the Milky Way in the Virgo Supercluster, but under Tully and colleagues’ definition, this region becomes just an appendage of the much larger Laniakea, which is 160 million parsecs (520 million light years) across and contains the mass of 100 million billion Suns.
Which kicked off this Twitter exchange between me and Lee Billings.
Your cosmic address: Earth, Sol System, Orion Arm, Milky Way Galaxy, Local Group, and now, the Laniakea Supercluster. http://t.co/eKbFMzJC8r

@LeeBillings Does this mean we need more numbers for our zip codes? Also, "Local" Group doesn't seem very descriptive. Everyone has one.
— Rand Simberg (@Rand_Simberg) September 3, 2014
@Rand_Simberg Given that we'd have to travel a few megaparsecs to shift our perspective to another "Local Group," I think the name is okay!
— Lee Billings (@LeeBillings) September 3, 2014
@LeeBillings Not consistent. Why does every other level get a name? Why not "Local Star System," "Local Galaxy," "Local Supercluster," etc.
— Rand Simberg (@Rand_Simberg) September 3, 2014
@Rand_Simberg You'd need to ask Edwin Hubble, who coined the term. Or maybe other mid-20th-century astronomers who adopted it?
— Lee Billings (@LeeBillings) September 3, 2014
Accordingly, I propose that we rename the Local Group the Hubble Group, in honor of its namer, and making it consistent with the other names. I will henceforth call it that. If anyone asks, I’ll explain.

So he came over before the land bridge, by water?
I think it’s crazy for the Corps of Engineers to acquiesce to the demands of the Siberian-Americans. They have no legitimate claim here.
