Text derives from texere, which means “to weave” and “to construct.” As Emerson states later in the essay, nature weaves texts: “A life in harmony with nature . . . will purge the eyes to understand her text . . . so that the world shall be to us an open book . . .…
While my 16yo son was mowing the lawn with our push-reel mower, our neighbor on one side slowed down his rider-mower to a crawl, grinned at my son, and said, “That’s some ancient technology you have there, boy.” I bought the reel mower thinking it would provide me with some exercise, and it’s quiet enough…
The water in the mantle rock, which could equal the amount of water in the world’s oceans, may be an integral part of sustaining water on the surface, Smyth said. It also implies that the Earth’s oceans likely formed from water stored deep beneath the Earth, rather than from a comet or asteroid, as other…
Alice in Quantumland: An Allegory of Quantum Physics is absolutely fantastic in its entirety, certain to engage the simultaneous states of entertainment and education with unequaled grace. Complement it with scientists’ answers to little kids’ questions about how the world works, then bend your mind by considering what it’s like to live in a universe…
Black holes do not exist—at least, not as we know them, says renowned physicist Stephen Hawking, potentially provoking a rethink of one of space’s most mysterious objects. A new study from Hawking also says that black holes may not possess “firewalls,” destructive belts of radiation that some researchers have proposed would incinerate anything that passes…
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…
Then I realized… I’m a guy who gets excited about grading papers in a park.
As a fan of Colossal Cave Adventure, I’m curious to know whether there’s an active volcano in this cave. Or at least a gold nugget room. Jonathan Sims catches up with me. Between us and the sunlit passage ahead stands a stalagmite that in profile resembles the paw of a dog. “The Hand of God…
“Every good lesson plan has a culminating activity,” says Dr. Audrey Quinlan. “Sondra, it took six months, but here’s your culminating activity.”
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…
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.
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…
Have I mentioned lately that I have awesome students? For a “Creative Critical Presentation” in my online American Literature survey, English major Tyler Carter created A Message from Hester Prynne, a 9-minute video that explores Hester’s psychology and spirituality, through music, dance, poetry, and cinematography. http://www.youtube.com/watch?v=ivxfKoZmF5k All the technology Seton Hill offers to its students…
From “global warming” to “climate change” to “ecosystem management,” the buzzwords have changed, but the issue remains: enthusiasm and hype are part of the PR machine that drives the public perception of science. When well-meaning activists rely on emotions as a shortcut to get the cooperation of the public, the fabric of civic discourse is…
Perhaps our most dangerous bias is that we naturally assume that everyone else is more susceptible to thinking errors, a tendency known as the “bias blind spot.” This “meta-bias” is rooted in our ability to spot systematic mistakes in the decisions of others—we excel at noticing the flaws of friends—and inability to spot those same…
I’d argue that what’s happening is that we’re becoming like the mal-formed weight lifter who trains only their upper body and has tiny little legs. We’re radically over-developing the parts of quick thinking, distractable brain and letting the long-form-thinking, creative, contemplative, solitude-seeking, thought-consolidating pieces of our brain atrophy by not using them. And, to me,…
