These dandelion children–equivalent to our “normal” or “healthy” children, with “resilient” genes–do pretty well almost anywhere, whether raised in the equivalent of a sidewalk crack or a well-tended garden. Ellis and Boyce offer that there are also “orchid” children, who will wilt if ignored or maltreated but bloom spectacularly with greenhouse care…. Gene variants generally considered misfortunes (poor Jim, he got…
In Pensylvania, homeshool kids have to take standardized tests every few years (at grades 3, 5, and 8). When he took the grade 5 exams last year, Peter did very well in all subjects, including math, though he 1) often says he hates math and 2) wastes a lot of time not doing math (staring…
I can’t say I understand, but someone invented every symbol and bit of notation that we use from emoticons to the alphabet. It’s cool to see the story of the need to invent new symbols. via Wired.
My sixth-grader has scored very well on standardized tests for math, but he finds a blank page of math problems intimidating and boring. He spends hours — literally hours — wasting time at the kitchen table, not doing his long division or word problems. Yet for pleasure, he reads Death by Black Hole: And Other…
Awesome Flash animation from the University of Utah, showing relative sizes from a coffee bean to a carbon atom. I wish it could also zoom out and show astronomical sizes, too, like this FSU slide show (not as smooth as the Utah one) or the famous Powers of Ten movie.
Yesterday in my journalism class, I asked everyone in the room to take out a coin and flip it twice, and raise their hand if it came up the same. Then I asked the ones whose hands were up to flip again, and keep their hand up if the coin came up the same yet…
I am not too happy about the way wild conclusions drawn from this self-published research periodically pop up in the media. Kudos to Liberman, from Language Log, who tries (yet again) to explain. The Paradox of Declining Female Happiness The best way to describe this, I think, would be to say something like: In the…
If language is as instinctive to humans as dam-building is to beavers, if every 3-year-old is a grammatical genius, if the design of syntax is coded in our DNA and wired into our brains, why, you might wonder, is the English language in such a mess? Why does the average American sound like a gibbering fool every time he opens his mouth or puts pen…
For anyone who’s ever forgotten something or someone they wish they could remember, a bit of solace: Though the memory is hidden from your conscious mind, it might not be gone. —Wired
Not as cleverly written as that video that has a line or two about each U.S. president (which I can’t locate at the moment) but still very nicely done.
A team of scientists from Britain, the United States and Papua New Guinea found more than 40 previously unidentified species when they climbed into the kilometre-deep crater of Mount Bosavi and explored a pristine jungle habitat teeming with life that has evolved in isolation since the volcano last erupted 200,000 years ago. In a remarkably…
I remember some years ago reading an article that used a similar strategy to describe exactly what it would feel like to stand on Mars. One of things Ford wasn’t ready for is the weird smell. “From the [spacewalks] there really is a distinct smell of space when they come back in,” Ford said from…
Zombie math. Yay! (PDF. Boo!) Zombies are a popular figure in pop culture/entertainment and they are usually portrayed as being brought about through an outbreak or epidemic. Consequently, we model a zombie attack, using biological assumptions based on popular zombie movies. We introduce a basic model for zombie infection, determine equilibria and their stability, and…
Teale Fristoe reviews The Great Flu. In the game, the player acts as the head of the World Pandemic Control during the outbreak of an unknown flu. As the game progresses, the player must take actions, such as dispatching research teams, dispensing medication and face masks, and closing schools and airports, in an attempt to…
Imagine if all teaching happened like this… if all persuasion came from demonstrations like this. World Science Festival 2009: Bobby McFerrin Demonstrates the Power of the Pentatonic Scale from World Science Festival. I’ve watched it three more times since blogging it, and it still makes me smile.
Lunar Lander — the game — at 40. Among the millions who watched the Apollo 11 landing was a 17 year old Massachusetts high school student named Jim Storer. In the fall of 1969, around the time of the Apollo 12 launch, Storer took his inspiration to class with him. There, he programmed a simple…
Tom Wolfe (author of space program biography The Right Stuff (which incidentally was the movie I took my first-ever date to see back in 1983) ) describes how the Cold War derailed the grand adventure of space exploration. Shockingly, the decay started while the Apollo program was still underway. [I]n October 1969, I began to…
The first man on the moon doesn’t feel his life is defined by being the first man on the moon? As if the world would remember much more than Armstrong’s “one piece of fireworks”? Would his name belong beside Magellan’s or Marco Polo’s if not for Armstrong’s singular achievement? —Paul Farhi, Washington Post
