To begin with, the terms “hypergiant” and “supergiant” are both a bit general. For the most part, these terms are loosely used to refer to the largest and most luminous (brightest and thus most energetic) stars in the universe. The exact term that one should use depends on the specific star that one is discussing…
For all the reform campaigns over the years, most schools continue to teach math and science in an off-putting way that appeals only to the most fervent students. The mathematical sequence has changed little since the Sputnik era: arithmetic, pre-algebra, algebra, geometry, trigonometry and, for only 17 percent of students, calculus. Science is generally limited…
Wow… what a drab, unquoteworthy, unsoundbiteable, graphics-free presentation of findings that will be of tremendous interest to the general public. TV but not electronic games predicted a small increase in conduct problems. Screen time did not predict other aspects of psychosocial adjustment. Further work is required to establish causal mechanisms..
Beautiful, beautiful science writing by Dennis Overbye. The “God particle” became the Prize particle on Tuesday. Two theoretical physicists who suggested that an invisible ocean of energy suffusing space is responsible for the mass and diversity of the particles in the universe won the Nobel Prize in Physics on Tuesday morning. They are Peter Higgs,…
Where did this idea of parallel universes come from? Science fiction is an obvious source: in the 1960s, Captain Kirk met his ‘other self’ in a Star Trek episode called ‘Mirror, Mirror’, while Philip K Dick’s novel The Man in the High Castle (1963) imagined an alternate world in which the US was a Nazi…
“There was a lot of writing involved. The one that stands out the most is, we were asked to compose a tweet, a limerick, or a haiku. I believe I did a limerick, and it goes: ‘Eyes fixed, gazing off into space My mind in awe of the human race This is all dizzying to…
With water already obscuring his vision, he had to turn upside down in order to release his safety cable. “Two things happen: the Sun sets, and my ability to see — already compromised by the water – completely vanishes, making my eyes useless; but worse than that, the water covers my nose — a really…
Many people think classical music is going to enhance brain function (the Mozart effect) or playing particular games sharpens ones cognitive function. These theories have been looked at in detail and they don’t stand up. It is disappointing in a way, but what we have learned is that exercise is the key thing for brain…
I took my daughter to an Alice-in-Wonderland-themed library summer reading wrapup party, where she threw herself into every craft table. Then she wore one of her creations as we went grocery shopping. Meanwhile, my son, who stayed home to watch another DVD lecture on superstring theory, took out the garbage without being asked. Today…
I keep a silly personal blog devoted to a six-legged toy that both my kids have outgrown but which still amuses me. I sometimes use that blog, and that toy, in classroom activities, and occasionally students develop an affection for what I called a “hectopus” (combining “hexagon” with “octopus,” though I concede “hexapus” would have…
“Peter, if black holes aren’t a good conversation starter at the picnic, what else might you try?” “Superstring theory?” That’s my boy.
The researchers found that each singer’s heartbeat was linked to the song’s melody – i.e. the speed and structure of the music. They also found that when the choir sang together, their heart rates tended to increase and decrease at similar times. “As soon as the singing begins, (the hearts) start following each other,” Vickhoff…
We live in an elegant universe. The cosmos is like a string symphony. Genes are selfish. There is an endless battle between thermodynamics and gravity. Do you love these statements, or hate them? The reading world gets pretty divided over whether or not it’s okay to apply metaphors and similes to descriptive science writing. It…
In between today’s various events, I dashed into the store for milk. As I was preparing to back out of my space, I saw a little old lady pushing her cart along, not realizing that my engine was running and I was about to back out. To make a long story short, I didn’t try…
Wisdom from science writer John Horgan. [I]t is precisely because science is so powerful that we need the humanities now more than ever. In your science, mathematics and engineering classes, you’re given facts, answers, knowledge, truth. Your professors say, “This is how things are.” They give you certainty. The humanities, at least the way I…
Can’t wait until we get this end-of-year state-mandated testing/evaluation over with, so my son can go back to reading stuff like this guy’s book. “Reality is structured to a series of moments so that anything that is real is real in a moment of time, and if something appears to persist in time, that’s because…
Last year, NASA announced that the Curiosity rover had found preliminary evidence of an ancient streambed, indicating that water once flowed freely on Mars. After a few more months of study, that preliminary announcement has been confirmed – Curiosity has found the remains of an ancient stream. —Forbes.
“You don’t like to think about a holocaust, but it’s quite possible,” he said. He referred to the long-standing belief among many anthropologists that H. sapiens exterminated Neanderthals with superior weapons and intellect. For a long time, there seemed to be no other explanation for the rapid disappearance of Neanderthals after H. sapiens arrived in…
The possibilities of combining Civil War re-enactment and steampunk fantasy role-playing are mind-boggling. Just imagine Rhett Butler steam-flying Scarlet out of Atlanta. The American Civil War brought about great advances in the use of technology in warfare. Balloons, railroads, ironclad ships, and even a submarine were demonstrated throughout the conflict, and new ideas were constantly…
