If your father is an English professor, how do you respond to poorly written signs in a kiddie park? Everywhere I go, I like taking pictures of signs with mistakes that make good classroom proofreading examples. Shortly after I moved to Western Pennsylvania, I learned that Idlewild Park is the regional version of Disneyland. Every…
NYT: T. rex shared more of its genetic makeup with ostriches and chickens than with living reptiles, like alligators. On this basis, the research team has redrawn the family tree of major vertebrate groups, assigning the dinosaur a new place in evolutionary relationships. Similar molecular tests on tissues from the extinct mastodon confirmed its close…
One hundred different people hitting a drum, from age 1 to 100. A short film by Lenka Clayton and James Price.
Jay Dixit, in Psychology Today, surveys research that considers dreams to be the brain’s training grounds for real-world emergencies. The idea that dreams are a dojo for perfecting waking activities fits well with what is already known about practice. Mental rehearsal through visualization improves skills, enhances learning, and changes the brain, polishing performance in almost…
The New Statesman: With only few days remaining in 2007, the indications are the global temperature for this year is the same as that for 2006 – there has been no warming over the 12 months. But is this just a blip in the ever upward trend you may ask? No. The fact is that…
Blogged as a reference, for the next time I have to introduce students to semiotics (ytmnd.com).
Footage from a NASA camera, via CBS:
From the New Yorker: It may seem strange that this last observation could have surprised anyone, but in Galileo’s time people assumed that the Milky Way must be some kind of continuous substance. It truly resembled a streak of spilled liquid–our word “galaxy” comes from the Greek for milk–and it was so bright that it…
In Texas, spiders have learned to cooperate. And I, for one, salute our new arachnid overlords. But Tuesday afternoon, thousands of Texas spiders were back at it, working to rebuild an immense spider web at Lake Tawakoni State Park that at one time stretched about 200 yards, covering bushes and trees to create a creepy…
This evening, I was out in the yard playing with the kids, when they noticed the full moon rising above a house a little ways down the street.
Roy F. Baumeister One can imagine an ancient battle in which the enemy was driven off and the city saved, and the returning soldiers are showered with gold coins. An early feminist might protest that hey, all those men are getting gold coins, half of those coins should go to women. In principle, I agree.…
Today we drove to the Thunder Mountain Lenape powwow, which was full of color and music. There were two drums — that is, groups of singers who sat around the same drum, chanting in rhythm. Dancers mostly moved around the circle. The younger the dancer, the fancier the footwork and the more the likelihood of…
Because so little primary historical work has been done on the classic text computer game “Colossal Cave Adventure”, academic and popular references to it frequently perpetuate inaccuracies. “Adventure” was the first in a series of text-based games (“interactive fiction”) that emphasize exploring, puzzles, and story, typically in a fantasy setting; these games had a significant…
An octopus with a porcelain plate stuck to its suckers has led to the discovery of a hoard of ancient pottery, South Korean scientists say. —Treasure trove ‘found by octopus’ (BBC) Thanks for the link, Rosemary.
Statistics collected over two decades show an alarming decline in the performance of America’s boys–in some respects, a virtual free fall. Boys were doing poorly in school, abusing drugs, committing violent crimes and engaging in promiscuous sex. Young males lost ground by many behavioral indicators at some point in the 1980s and ’90s: sharp plunges…
Sometimes called the reptilian brain because its basic structure dates back to our reptile ancestors, the brain stem is largely devoted to our most primal instincts, far removed from the complex, higher-brain skills that allow us to understand humor. And yet somehow, in this primitive region, we find the urge to laugh. —Steven Johnson —What’s…
“At first I didn’t believe a seagull was capable of stealing crisps. But I saw it with my own eyes and I was surprised. He’s very good at it.” —Seagull becomes crisp shoplifter (BBC) Very strange. My brother-in-law Robert sent it to me.
“I have never forgotten the magic night that my own father, like his father and his father’s father before him, gently woke me, bundled me up in a warm blanket and quietly led me outside to see the Northern Lights for the first time,” said the elder Meier, dejectedly sipping a cup of hot cocoa…
I used to think that things like rocks and buildings and my own skeleton were fairly solid. But they’re made up of atoms, and atoms, as you can see here, contain so little actual material that they can barely be said to exist. We are all phantoms. —Hydrogen Atom Scale Model (Phrenopolis)
‘One approach to seeing the future is through scenarios — carefully crafted “what if?” stories that let us imagine several different outcomes’, the book says. It suggests holding a ‘scenario party’ (seriously) where you can ‘pool the imaginations and experiences of your friends’. In short: we have no idea what the future will look like,…
