Much to my embarrassment, I hadn’t considered some of the mortal dangers faced by giraffes. 

“If there’s a lightning leader already approaching the ground, it will certainly look for something tall to hit in its immediate vicinity,” says Professor David Smith of the University of California’s physics department. “Since water is pretty conductive (particularly salty water), your giraffe is a pretty good conductor and probably does attract lightning pretty well.”

Oh, it gets sadder and a little bizarre:  

Lightning strikes may be a significant danger to giraffes in environments that have few tall trees and are topographically or geologically predisposed to attract lightning. One eyewitness report suggests that, during lightning storms, giraffes lower their heads and may even compete with one another to become lower in height… Between 1996 and 1999 the Rhino and Lion Reserve near Krugersdorp, South Africa, had two of its three giraffes killed by lightning – the third animal, a juvenile, was also struck but survived. Betsy the giraffe was killed by lightning at Walt Disney World in Florida in 2003 in front of lots of witnesses.

I’m guessing the combination of giraffes and lightning isn’t something readers had given much thought either. See? We’re learning together.

The astronauts were more than excited to feel the ground, though standing on it was too hard for them after spending so many days in the state of weightlessness.

After 191 days, Soyuz TMA-11 and its three human occupants returned to Earth from the International Space Station, landing in Kazakhstan, April 19, 2008. A partial separation failure caused a ballistic re-entry that in turn caused the spacecraft to land 475 km from its intended landing site. The occupants, Yuri Malenchenko, Peggy Whitson and Yi So-Yeon, were assisted by local residents who discovered the charred spacecraft resting in their fields.

40 years ago today, some hairless apes did a very daring and clever thing. Around half a billion other hairless apes watched it happen on TV. Such was the daring and cunning involved, and such was the uncertainty of the outcome, it’s worth reposting this. Here’s David Sington’s 2007 documentary, In the Shadow of the Moon, in which the surviving Apollo crew members recount their remarkable, 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.

For newcomers, three more items from the archives.

Freeloading and Snobbery. 

Arts establishment claims to be “suppressed,” sneers at the little people, demands free money.

I’m not convinced that the reduction of taxpayer subsidy for loss-making plays qualifies as “suppression.” And reluctant taxpayers please take note: Despite all the years of providing handouts, you’re now on the side of the oppressor.

Womanier Stuff.

The comedic potential of Women’s Studies newsgroups.

As a result of all this “questioning” and “confronting” of logic perhaps we can look forward to the first feminist computer, which will presumably operate on more “wholistic” non-logical principles. If such a device could be built, I’m confident it would generate answers that are ideologically agreeable, if not actually correct.

Exposure.

Atom bombs and Moon landings. The photographic essays of Michael Light.

One incidental detail… illuminates the unique comic potential of practical nuclear physics. Ted Taylor was a miniaturisation expert involved in many of the early atmospheric experiments. On June 5th, 1952, during the test explosion of a 14 kiloton device in the Nevada Desert, Taylor used a parabolic mirror to focus the bomb’s glare and light his cigarette.

Poke about in the greatest hits.

No, seriously. See for yourselves. 

I quote:

In January 2004, the carcass of a 50-ton sperm whale explodes in a Taiwanese city centre. [National Geographic Channel] examines the physics and the biology of this 100,000-pound animal whose body was destroyed by its own internal forces. On the way to Tainan University for research, the whale exploded due to volatile gas build up in the abdomen.

At this point, further comment seems unwise. It would only lead to jokes involving the ending of Watchmen and “volatile gas build-ups.”

Oliver Kamm on the inversions of being “progressive”:

Notions once considered reactionary, even extreme, have insinuated themselves into the mainstream of right-thinking (that is, left-thinking) social idealism. When you encountered someone of professed left-of-centre opinions, you used to be able to draw broad but important, and generally reliable, inferences about what these entailed. They included, at a minimum, commitments to secularism, freedom of expression, individual liberty against collective authority, women’s rights, homosexual equality and the combating of xenophobia. Times have changed. Now these stances are unusual, even heterodox. […]

When, last year, suicide bombers attacked the Danish Embassy in Pakistan, killing six people and wounding more than 20, a Danish journalist writing for The Guardian commented that the attack was “of course, indefensible, but it raises questions about the wisdom of the much-debated cartoons and Danish reactions to Muslim wrath.”

(For more on the Guardian journalist in question and his “of course, but” manoeuvre, see, for instance, this.)

The “of course, but” formulation is worse than a dreary cliché. It indicates a liberalism evacuated of content. Those who prize social unity and order will tend to believe that people’s deepest feelings and beliefs should be accorded respect. But respect for ideas is never an entitlement. It depends on their intellectual resilience in public debate. No free society can treat people’s deepest beliefs as sacrosanct. They are fair game for hostile and derisive criticism. That is how knowledge advances. […]

No one has a right to the protection of feelings. If politics concerns itself with mental states, there is no limit to how far legislation can intrude on people’s lives. The task of progressive politics is to protect liberty, not least by attacking the accumulation of bad ideas. Yet to many on the Left, the individual, inquiring mind is of far less importance than the representation of designated groups.

Colliding Particles is a series of short films by Mike Paterson following a team of physicists at the Large Hadron Collider. The latest film, Problems, covers helium mishaps, staring at blackboards and the search for missing music.
