The comedic potential of academic feminism will not be unknown to regular readers of this site. Some of you may have fond memories of Dr Sandra Harding, an alleged “feminist philosopher of science,” who claims that Einstein’s theories of relativity are “gender-biased” and thus disreputable. Ms Harding famously described Newton’s Principia as a “rape manual” and claimed that rape and torture metaphors could be used to usefully describe its contents. Harding’s most famous “work” is essentially a pile of unsupported claims, false equivalences and comical non sequitur. That she’s employed in academia is, or should be, a minor scandal. Before you snigger too much, though, it seems Ms Harding’s worldview is not entirely without influence. Over at B&W, Ophelia Benson has been trawling through a Women’s Studies discussion group and unearthed the following gem:
Biology is a socially constructed concept too – dated. It categorizes and defines ‘organisms’ a certain way – not wholistically – and not the only way possible, I might add.
I am no science major,
A shock to us all.
but I know Einstein’s theories and physics has already proven most of the fundamentals of biology to be faulty.
Readers may be wondering how exactly the theories of General and Special Relativity – or some unspecified “physics” – have “proven most of the fundamentals of biology to be faulty.” Alas, our Women’s Studies devotee doesn’t seem to know and so, alas, nor will we.
I admit, I am a science heretic. It is a belief system and I’ve confronted it’s [sic] limitations – quite soundly and concretely – for my own understandings…
This is a surprisingly popular assertion – that the scientific method is a “belief system” and thus, allegedly, no better or more deserving of “privilege” than whatever it is it suits one to believe. As, for instance, when the Guardian’s Madeleine Bunting told her readers that “rationality is a social construction” while taking umbrage with the Enlightenment on grounds that it was now “being used against Islam.” This, one must suppose, is a very bad thing and to be avoided at all costs. To suggest that someone is wrong on points of fact or incoherent or amazingly credulous would be terribly unfair.
I was once told that “science is based on assumptions; an assumption is essentially a belief, so science is based on belief.” But the scientific method is actually based on the testing of formal hypotheses, as opposed to beliefs, which are not the same thing at all. Strictly speaking, a scientific hypothesis must be self-consistent, must explain existing observations and must predict new ones. These formal obligations and restraints are not comparable with the acceptance of erroneous or unverifiable assumptions as a priori truth. The scientific method is one of the best practical lessons in intellectual humility. As the mathematician Ian Stewart pointed out: “Science is the best defence against believing what we want to.” And the willingness to defer to evidence – as opposed to one’s own preferences – is the antithesis of fundamentalism, whether religious or political.
Brilliant Noise, by Ruth Jarman and Joe Gerhardt, is a short film about the Sun. Not so much twinkling as seething, spitting and flaring.

Starting up a major new particle accelerator takes much more than flipping a switch. Thousands of individual elements have to work in harmony, timings have to be synchronized to under a billionth of a second, and beams finer than a human hair have to be brought into head-on collision.
Attention nerdlings. Tune in to the LHC “first beam” broadcast, 9am-6pm. So far, so good.
Thanks to The Thin Man, here’s the 2007 documentary, In the Shadow of the Moon, in which the surviving Apollo crew members recount their remarkable, and at times moving, experiences. There’s previously unseen mission footage, an excellent score by Philip Sheppard, and keep an eye out for Kennedy’s extraordinary speech, about 13:20 in.
The film is also available in six parts here. Related: Freefall, Craters, Astronomical Odds.
Here’s a thing. Japanese surgeon Dr Norihiko Ishikawa demonstrates the precision of the da Vinci Surgical System by using its remote-control robotic arms to indulge in a spot of origami. The object he’s making – a crane – is about the size of a penny.

Related rather tenuously to yesterday’s comments:
A panoramic tour of the International Space Station. I can’t seem to find the sofa. Or the bar.
And because I know you like quizzes,
How long could you survive in the vacuum of space?
Here’s the third episode of the excellent BBC documentary series, The Planets. Titled Giants, the film follows the ingenuity and serendipity of the 1977 Voyager mission and its “grand tour” of the outer planets.
A happy alignment. Slingshot. Magnetic Jupiter. 3 million amps. Rings and ghosts.
Fearsome weather. Saturn’s other side. Shattered. Perfect timing. Still listening.

Further to Dr Abd al-Baset al-Sayyed’s call for the global adoption of “Mecca Time” – and the shocking discovery that “in Mecca there is no magnetic force” – here’s another nugget. In this clip from Saudi Arabia’s al-Majd TV, first broadcast in January 2005, Dr al-Sayyed shares the extraordinary news that people living in Mecca are “less affected by gravity.” No less remarkable is the claim that NASA discovered “short wave radiation” emanating from Mecca – a discovery hastily concealed from the world at large. However, Dr al-Sayyed is sure this sacred Mecca radiation is “infinite” and extends well past the planet Mars.

For some reason I’m reminded of this.
