Darwin’s children’s drawings on display

Charles Darwin used sheet after sheet of paper when writing On the Origin of Species, since redrafting before the days of Microsoft Word meant writing the whole thing out again. Only a handful of these draft papers have survived, mostly because Darwin gave his used sheets to his children for use as drawing paper.

Next week one such sheet will go on display in a new exhibition at Cambridge University Library. Named “Battle of the Vegetables” by Library staff, it depicts a battle between one man riding a carrot and another on what could possibly be a stale potato.

Did Michael Jackson’s death contribute to climate change?

Duncan Graham-Rowe of the Guardian asks whether we should consider the carbon cost of all the increased web activity following the singer’s death. I’ve discussed the carbon cost of Googling before – 0.2g per search, according to the company’s own figures.

As one commenter points out, if you added up the tiny contributions of all the tributary Tweets and YouTubes they probably wouldn’t exceed the Jackson’s personal carbon footprint, considering the lavish life he led.

The Guardian’s James Randerson also chimes in to say the point of the article isn’t really the carbon cost of Jackson’s death, but to highlight the issue of unsustainable internet growth. Whilst this is a problem, I can’t imagine that alternative methods of information distribution are any greener. As with many climate change conundrums, the answer is far from clear.

What’s on alien TV?

Webcomic Abstruse Goose has this rather nice image of what aliens might be watching on TV. When TV signals are broadcast some of them radiate out from the Earth, and could be picked up by any extraterrestrials out there. Like all electromagnetic radiation, the signals travel at the speed of light, so depending on how far from Earth the aliens are it’s going to take them a while to receive our latest programmes.

Whilst inhabitants of the relatively near Sirius system might have been enjoying episodes of Family Guy and The Sopranos for the past few years, everyone out in Aldebaran is still waiting for coverage of World War II to arrive. I just hope any aliens out there will forgive us for polluting space with broadcasts of Big Brother…
