In most situations, the person juggling e-mail, text messaging, Facebook and a meeting is [not multitasking, but] really doing something called “rapid toggling between tasks,” and is engaged in constant context switching. As economics students know, switching involves costs. But how much? When a consumer switches banks, or a company switches suppliers, it’s relatively easy…
“Hear my voice. Alexander Graham Bell.” That was really quite thrilling. In that ringing declaration, I heard the clear diction of a man whose father, Alexander Melville Bell, had been a renowned elocution teacher (and perhaps the model for the imperious Prof. Henry Higgins, in George Bernard Shaw’s Pygmalion; Shaw acknowledged Bell in his preface…

Great video about subatomic particles, from Piled Higher and Deeper.
As digital texts and technologies become more prevalent, we gain new and more mobile ways of reading—but are we still reading as attentively and thoroughly? How do our brains respond differently to onscreen text than to words on paper? Should we be worried about dividing our attention between pixels and ink or is the validity…
My artsy daughter loves stories about science far more than she loves science; she has won “Best Display” for her age group in a science fair. When my son was 5, when given the choice he would invariably ask me to read him a nonfiction book rather an a fiction book; he has won “Most…
Since he started teaching at Johns Hopkins University in 2005, Professor Peter Fröhlich has maintained a grading curve in which each class’s highest grade on the final counts as an A, with all other scores adjusted accordingly. So if a midterm is worth 40 points, and the highest actual score is 36 points, “that person…
Patience and hard work are also attributes of hunters, peasants, and Benedictine monks. What sets scientists apart is their rigorous observation of natural phenomena, allowing patterns to emerge that can be expressed in abstract formulae, which, in turn, can be applied to produce identical results any time they are reapplied in identical conditions. To “do…
An asteroid is making the closest known fly-by for a rock of its size today, just hours after a meterorite crashed to Earth in Russia, with nearly a thousand people injured by space debris in an event unprecedented in modern times. Scientists insist the events are purely coincidental… Follow all the latest news, reaction, and…
Most teachers are those who, not surprisingly, have made it through the educational system smoothly enough to replicate it, even when they think of themselves as radical reformers of that system. Especially English teachers. English teachers are the gatekeepers to the normal brained. (I see this all the time when I am hanging out with…
Beatrice the Biologist: How the Brain Works.
[S]ize seems to predict lifespan. The formula seems to be nature’s way to preserve larger creatures who need time to grow and prosper, and it not only operates in all living things, but even in the cells of living things. It tells animals for example, that there’s a universal limit to life, that though they…
If you took everything human beings have ever written — an estimated 50 billion megabytes of text — and stored it in DNA, that DNA would still weigh less than a granola bar.”There’s no problem with holding a lot of information in DNA,” Goldman says. “The problem is paying for doing that.”Agilent waived the cost…
Let’s get this straight first… Flu is the respiratory sickness caused by the influenza virus that threatens the functions of your nose, throat and lungs. Flu is a virus that spreads by injecting its genetic information into the nuclei of your cells. In other words, it hijacks the good cells and controls their function to…
The Twitter version: There’s a slight decrease in violent crime when violent movies are playing. People who like violence tend to go watch the movie instead of going out and doing violent things. Laboratory experiments in psychology find that media violence increases aggression in the short run. We analyze whether media violence affects violent crime in…
In one version of Hawking’s eulogistic story, we praise the smartest person in the world, the brilliant physicist, one of the greatest cosmologists of our time. He fits perfectly well with our conception of how science and its heroes work: To be a genius all one needs is a powerful – a “beautiful” – mind.…
Really helpful definition from a “Pinkalicous” children’s theater study guide. That’ll clear everything right up for the kiddos, won’t it?
If you smoke two cigarettes, you lose 30 minutes of your life. Exercise for 20 minutes, and you gain two units of microlife. Over time bad habits accelerate your aging, and good habits slow it down… — Scientific American.
My friend Anastasia gave me a home-made lip-balm kit for my 10yo daughter. A blizzard the day after Christmas was the perfect opportunity to stay home and try it out.
