Maybe the universe is a trillion years old and has experienced several big bangs and big collapses over the years. “People have inferred that time began then, but there really wasn’t any reason for that inference. What we are proposing is very radical. It’s saying there was time before the big bang.”

Richard Dawkins has a new book coming out in October called The God Delusion. For some reason, I don’t see this being a big seller in the US.
Wired magazine reports on the revolutionary food and strange equipment (antigriddle!) used by chef Grant Achatz in the kitchen at Alinea. “The technology allows us to get to the essence of food. It allows you to be more true with flavor, not less true.”
Google can be used for finding scientific papers that are more popular (and influential?) than their number of citations would otherwise indicate. “The technique might also emerge as a more useful measure of scientific impact than merely the number of citations alone.”

In the 1960s, a young Al Gore had the good fortune to study under Roger Revelle at Harvard University. Revelle was one of the first scientists to claim that the earth may not be able to effectively deal with all of the carbon dioxide generated by the earth’s rapidly increasing human population. The American Institute of Physics called Revelle’s 1957 paper with Hans Suess “the opening shot in the global warming debates”. Gore took Revelle’s lessons to heart, becoming a keen supporter of the environment during his government service.
Since losing the 2000 Presidential election to George W. Bush, Al Gore has focused his efforts on things other than politics; among other things, he’s been crisscrossing the world delivering a presentation on global warming. Gore’s presentation now forms the foundation of a new film, An Inconvenient Truth (view the trailer).
In organizing my thoughts about the film, I found I couldn’t improve upon David Remnick’s review in the New Yorker. In particular:
It is, to be perfectly honest (and there is no way of getting around this), a documentary film about a possibly retired politician giving a slide show about the dangers of melting ice sheets and rising sea levels. It has a few lapses of mise en scene. Sometimes we see Gore gravely talking on his cell phone—or gravely staring out an airplane window, or gravely tapping away on his laptop in a lonely hotel room—for a little longer than is absolutely necessary. And yet, as a means of education, “An Inconvenient Truth” is a brilliantly lucid, often riveting attempt to warn Americans off our hellbent path to global suicide. “An Inconvenient Truth” is not the most entertaining film of the year. But it might be the most important.
Watching the film, I realized — far too late to move to Florida and vote for him in 2000 — that I’m a fan of Al Gore. He’s smart & intellectually curious (the latter doesn’t always follow from the former), understands science enough to explain it to the layperson without needlessly oversimplifying, and despite his reputation as somewhat of a robot, seems to be more of a real person than many politicians. As Remnick says:
One can imagine him as an intelligent and decent President, capable of making serious decisions and explaining them in the language of a confident adult.
The film has some small problems; many of the asides about Gore’s life (particularly the 2000 election stuff) don’t seem to fit cleanly into the main narrative, the connection it makes between global warming and Katrina is stronger than it should be, and the trailer is a little silly; this is a documentary about Al Gore and global warming after all, not The Day After Tomorrow or Armageddon. But the film really shines when it focuses on the presentation and Gore methodically and lucidly making the case for us needing to take action on global warming. An Inconvenient Truth opens in the US on May 24…do yourself a favor and seek it out when it comes to your local theater.
A Manchester scientist has come up with a mathematical formula to assess the perfection of the female derriere. “Dr Holmes said that Kylie Minogue, whose celebrated bottom relaunched her career with the help of a pair of hotpants, would almost certainly score a perfect 80.”

Profile of Daniel Dennett, “Darwinian fundamentalist” and author of a new book that argues that “religion, chiefly Christianity, is itself a biologically evolved concept, and one that has outlived its usefulness”.

Sociology study indicates that atheists are the least trusted group of people in America. “Researchers found that Americans rate atheists below Muslims, recent immigrants, homosexuals and other groups as ‘sharing their vision of American society.’ Americans are also least willing to let their children marry atheists.” Also, “those surveyed tended to view people who don’t believe in a god as the ‘ultimate self-interested actor who doesn’t care about anyone but themselves.’” (via dg)

Watched America’s Stone Age Explorers on PBS this evening, a summary of recent findings about who the first Americans were, where they came from, and when they arrived. Recent genetic and archeological evidence suggests they arrived earlier than generally accepted and may have originated from Europe rather than Asia.
20-year-long study shows that children who were whiny and insecure tend to grow up to be conservatives and “confident, resilient, self-reliant” children tend to grow up to be liberals. “He reasons that insecure kids look for the reassurance provided by tradition and authority, and find it in conservative politics. The more confident kids are eager to explore alternatives to the way things are, and find liberal politics more congenial.”
To Dr. David Hague, human pregnancy is a struggle between the fetus and mother. Evolutionarily speaking, the fetus “wants” as many resources as possible for itself while the mother “wants” to do what she can to spread her resources across as many children as possible. In theory, this is a cause of the many serious health problems surrounding pregnancy.
Update: Carl Zimmer has more about this on his blog.
Short Elizabeth Kolbert article on the conservative response to climate change. “The new argument making the rounds of conservative think tanks, like the National Center for Policy Analysis, and circulating through assorted sympathetic publications goes something like this: Yes, the planet may be warming up, but no one can be sure of why, and, in any case, it doesn’t matter — let’s stop quibbling about the causes of climate change and concentrate on dealing with the consequences.”

Now that I’ve closed the comments on the question of the airplane and the conveyor belt, I’m still getting emails calling me an idiot for thinking that the plane will take off. Having believed that after first hearing the question and formulating several reasons reinforcing my belief, I can sympathize with that POV, but that doesn’t change the fact that I was initially wrong and that if you believe the plane won’t take off, you’re wrong too[1].
The only thing is, I’m not sure how to prove it to you if you don’t understand the problem and the physics involved. I guess I could urge you to read the question and answer again carefully. I could tell you that not only does the conveyor belt not keep the plane stationary with respect to the ground but it *can’t* keep that plane stationary with respect to the ground[2] and once you know that, of course it’ll take off. My pal Mouser has a Ph.d in Physics from MIT and he says the plane will take off:
The airplane would take off normally, with the wheels spinning twice as fast as normal and a *slight* reduction in acceleration due to added friction.
Is that enough to convince you?
[1] This situation reminds me of Richard Dawkins’ and Jerry Coyne’s assertion that “one side can be wrong”.
[2] The motion of the conveyor belt does nothing[3] to affect the movement of the plane when the plane is in motion…it doesn’t matter if it’s moving forward, backward, at 2 MPH, or at 400 MPH. If the plane were on castors that could spin freely from side to side as well as front to back, that treadmill could be spinning 100 MPH to the left and the plane would take off.
[3] Well, almost nothing. The friction of the turning wheels will slow things down a bit, but not enough to not make the plane take off. After all, the main function of the wheels of a plane is to provide a near-frictionless interface with the ground (or whatever the plane happens to be taking off from).
