Extended oddments

Some more items, but these ones are categorized in groups.

Shakespeare:

I read Niven's story "Chicxulub" in a recent issue of Asimov's, and wasn't sure what the title meant, so I looked it up. Turns out in real life it's the location of the asteroid impact believed (at least by some) to have caused the mass extinction at the K/T boundary (end of Cretaceous period, beginning of Tertiary), 65 million years ago. Also turns out there's some amazing stuff about it online:

  • Astronomy Picture of the Day for 26 February 2000 shows gravity and magnetic field data for the region. If you turn it upside down, it looks a little like a C-in-circle character, leading me to wonder if perhaps someone was just putting a Copyright stamp on the Earth, to prevent piracy.
  • The NASA/UA Space Imagery Center has web pages at the U. Arizona Lunar and Planetary Laboratory with information about Chicxulub.
  • That whole site is worth looking at, but particularly astonishing are the pages on the regional effects ("Because part of the crater was in a shallow sea, giant tsunamis radiated across the Gulf of Mexico. . . . If the impact had occurred in a deep ocean basin, these waves might have been 4 to 5 km high and affected coastlines as far away as 10,000 km. Because the Chicxulub impact occurred in relatively shallow water, approximately 100 m deep, the waves were probably not nearly as large. One estimate suggests waves that hit the Texas coast were 'only' 50 to 100 m high.") and global effects. ("Current estimates suggest that the dust made it too dark to see [worldwide] for 1 to 6 months and too dark for photosynthesis for 2 months to 1 year. . . ." And then there were the greenhouse gases, the acid rain, the ozone layer damage, the massive forest fires, etc.)

A couple of movies of note:

You may be familiar with the idea of face-blindness/prosopagnosia. I sometimes think that I may have a very very minor form of it, but more likely I'm just not very observant. Anyway, I find it fascinating.

    I found this item only a few hours too late to add it to the entry: turns out that the asteroid may’ve killed off the dinosaurs by changing their sexes. Specifically, temperature affects what sex a crocodilian egg turns into (!), and the temperature change from the asteroid may’ve resulted in too many male dinos and too few females.

    “Franz Kafka’s It’s a Wonderful Life” has been on my to-see list for years, but I can never convince my fellow movie-renters to go for it when I see it on the shelf. When it comes up in conversation elsewhere, half the time people think I’m just making up the title as a joke.
