Lectures for a New Year: Parrots, the Universe, and Everything

Today I've got a doozy of a lecture for you. I present what is likely Hitchhiker's Guide to the Galaxy author Douglas Adams's last public appearance -- he died of a heart attack on May 11, 2001, mere days after this talk at UC San Diego was filmed. This is a man in the prime of his life, about to be struck down. And he is cracking wise throughout, telling truly wonderful, engaging stories, but with a shattering message: just as our world is being pulled together by information technology, we are destroying species faster than ever before (unless you count, as he says, the points at which Earth has been hit by asteroids).

In the lecture, Adams recounts his hilarious adventures traveling the world studying endangered wildlife, learning about the odd, endearing lives of vanishing species...and what animal extinction means for the lives of humans. The talk was given about a decade after Adams published his favorite book, Last Chance to See. He took to the stage eleven years after the book was released, to tell its story -- this was a lecture of love, not promoting a hot new book. As Adams says in his introduction: "Virtually every author I know, their own favorite book is the one that sold the least."

Even if you're a fan of The Hitchhiker's Guide, you may not have read Adams's other work, or even heard of it. (I haven't read Last Chance to See and have only the vaguest familiarity with his Dirk Gently novels.) This lecture will convince you that the man's most under-appreciated book is well worth a read.

Topics: a monkey looking at a lemur, advances in twig technology, dragons, snakes, the Venom Fridge, forgetting how to fly, the Blue-footed Booby, the Friendship Store, condoms for recording dolphins, humans, and Carl Sagan.

Not covered: life, the universe, and everything.

For: anyone interested in nature, people who like jokes, fans of Douglas Adams, anyone who enjoys a good yarn about the natural world, and those who are not scandalized by a fleeting f-bomb or two.

Representative quote:

So just imagine if you will, this male Kakapo sitting up here, making all this booming noise which, if there's a female out there--which there probably isn't--and if she likes the sound of this booming--which she probably doesn't--then she can't find the person who's making it! (Laughter.) But supposing she does, supposing she's out there--but she probably isn't--she likes the sound of this booming--she probably doesn't--supposing that she can find him--which she probably can't--she will then only consent to mate if the Podocarpus tree is in fruit! (Laughter.)

Now we've all had relationships like that ... (Laughter.) (Applause.)

Further Reading

The book is Last Chance to See, and it was made into a BBC 2 series featuring Stephen Fry. There was also a BBC Radio series in 1989, which is now available online for free...if you're in the UK.

If you're unfamiliar with Adams (which I find unlikely), check out his website, which notes that there is a Douglas Adams Memorial Lecture series. Hmm, I'll have to check that out. See also, his Wikipedia entry. Oh, and if you're going to be in London on March 11, 2012, there's a 60th birthday celebration for DNA!

Stones, Bones, and Wrecks
3500-Year-Old Mummy Discovered in Forgotten Egyptian Tomb

As the site of the ancient city of Thebes, the modern-day Egyptian city of Luxor is filled with archaeological treasures. But until recently, two forgotten tombs—both located in the necropolis of Dra' Abu el-Naga, an important non-royal cemetery—hadn’t been fully explored. Now, National Geographic reports that experts have finally excavated these burial sites and discovered a 3500-year-old mummy, along with ornate funerary goods and colorful murals.

While excavating one of the two tombs, known as Kampp 150, experts found linen-wrapped remains that Egypt's Ministry of Antiquities believes belong to either "a person named Djehuty Mes, whose name was engraved on one of the walls ... [or] the scribe Maati, as his name and the name of his wife Mehi were inscribed on 50 funerary cones found in the tomb's rectangular chamber."

In addition to the mummy, archaeologists discovered wooden statues, masks, earthen pots, a cache of some 450 statuettes, and around 100 funerary cones—conical mud objects, which were often positioned outside a tomb's center, and could have served as identifying markers or as offerings—inside Kampp 150.

The Associated Press reported that the second tomb, known as Kampp 161, is thought to be approximately 3400 years old—about 100 years newer than its neighboring chamber—as its design is characteristic of other such structures dating back to the reigns of Amenhotep II and Thutmose IV.

Inside Kampp 161, archaeologists discovered wooden funerary masks, a decorated coffin, furniture shards, and the mural of a festival or party depicting the tomb's unknown resident and his wife receiving ceremonial offerings.

German scholar Friederike Kampp-Seyfried surveyed and numbered both tombs in the 1990s, which is how they got their names, but she did not fully excavate nor enter either one.

Officials celebrated the rediscovery of the tombs on Saturday, December 9, when they publicly announced the archaeological finds. They hope that discoveries like these will entice foreign travelers to visit Egypt, as political unrest has harmed the country's tourism industry in recent years.

“It’s truly an exceptional day,” Khaled al-Anani, Egypt's antiquities minister, said in a statement. “The 18th dynasty private tombs were already known. But it’s the first time" anyone's ever entered them.

Check out some pictures of the newly revealed relics below.

Can You Figure Out This Newly Discovered Optical Illusion?
Kohske Takahashi, i-Perception (2017)
Kohske Takahashi, i-Perception (2017)

Ready to have your mind boggled? Take a look at the image above. What shape are the lines? Do they look like curves, or zigzags?

The image, spotted by Digg, is a new type of optical illusion published in the aptly named journal i-Perception. Discovered by Japanese psychologist Kohske Takahashi, it’s called the “curvature blindness illusion,” because—spoiler—the contrast of the lines against the gray background makes our eye see some of the lines as zigzags when, in fact, they’re all smooth curves.

The illusion relies on a few different factors, according to the three experiments Takahashi conducted. For it to work, the lines have to change contrast just at or after the peak of the curve, reversing the contrast against the background. You’ll notice that the zigzags only appear against the gray section of the background, and even against that gray background, not every line looks angled. The lines that look curvy change contrast midway between the peaks and the valleys of the line, whereas the lines that look like they contain sharp angles change contrast right at the peak and valley. The curve has to be relatively gentle, too.

Go ahead, stare at it for a while.
