Dr. Mays uses the Simultaneous Action Selection mechanic to structure his lesson. He creates two decks of cards—one with names of different cellular components (e.g., ribosomes, endoplasmic reticulum) and another with a wide assortment of cellular functions and processes. He seats students in groups of five or six and…
“Right now, I’m a little thirsty, so I will drink a bit of water. And when I do that, I experience a thin slice of joy both in space and time,” he told CBC News. “It’s not like ‘Yay!”” he notes in Joy on Demand. “It’s like, ‘Oh, it’s kind of nice.’” Usually these events are unremarkable: a bite of food, the sensation…
"The reason kids go through this is probably because it's a Moebius strip," he said, referring to the sort of looped one-surface shapes Escher was fond of drawing. "It can't be drawn continuously, but it does have a perpetual flow." I think he was on to something. Most nine-year-olds can't draw, so when someone hands…
Begin with a story or explanation of the term. Modeling how you use the word in your life or in conversation may be helpful to students. Have students put information into their own words. This process, which I call “recoding,” is necessary to make sure students understand the word. This is a vital step in the memory…
There is nothing really the matter with the concept of g; it is just that we have misused it by making it the omnipresent concept in our study of cognitive abilities. Intelligence is important on three levels, namely, brain physiology, individual differences, and social trends (collectively, BIDS). The core of a BIDS…
I feel a sudden clear focus and perspective. There is no time for anything inessential. I must focus on myself, my work and my friends. I shall no longer look at “NewsHour” every night. I shall no longer pay any attention to politics or arguments about global warming. This is not indifference but detachment — I still…
But why should comets become more likely to hit us every million years? Here we launch ourselves into deep speculation. It has been suggested that the sun has a sister star, and the two orbit each other with a periodicity of about 26 million years. This hypothetical binary partner, which has never been seen but which…
It is a sign of the speed at which events are moving that Hurst and Blackett’s unexpurgated edition of Mein Kampf, published only a year ago, is edited from a pro-Hitler angle. The obvious intention of the translator’s preface and notes is to tone down the book’s ferocity and present Hitler in as kindly a light as…
For me, the most paralyzing news was that Nature was no conservationist. It needed no help from us in taking the planet apart and putting it back together some different way, not necessarily improving it from the viewpoint of living things. It set fire to forests with lightning bolts. It paved vast tracts of arable…
Whenever a statistician wants to predict the likelihood of some event based on the available evidence, there are two main sources of information that have to be taken into account: (1) the evidence itself, for which a reliability figure has to be calculated; and (2) the likelihood of the event calculated purely in…
Sometimes the term "steel man" is used to refer to a position's or argument's improved form. A straw man is a misrepresentation of someone's position or argument that is easy to defeat: a "steel man" is an improvement of someone's position or argument that is harder to defeat than their originally stated position or…
Our labor world and all salaried workers, including school teachers and college professors, are now, at least subconsciously if not consciously, afraid that automation will take away their jobs. They are afraid they won't be able to do what is called "earning a living," which is short for earning the right to live…
Every bit in a computer is a wannabe Maxwell’s Demon, separating the state of “one” from the state of “zero” for a while, at a cost. A computer on a network can also act like a wannabe demon if it tries to sort data from networked people into one or the other side of some imaginary door, while pretending there is no…
It appeared that sixty-five percent of people would torture someone to death, if pressured to do so. The results made their way into both psychology and cocktail party conversation. But were they correct? At least one woman doesn't think so. Gina Perry, for her book, Behind the Shock Machine, traced as many…
Learn to Listen Rather Than Speak This one is a lot harder than it sounds, and I say this as someone who loves speaking and voicing her opinion on things. One of the greatest things we, as privileged people, can bring to a discussion being held by non-privileged groups is our closed mouths and open ears/minds. When…
evolution doesn't always proceed steadily
Lorenz and his team were working to develop a weather forecasting program on an early computer known as a Royal McBee LGP-30.21 They thought they were getting somewhere until the computer started spitting out erratic results. They began with what they thought was exactly the same data and ran what they thought was…
In so far as a scientific statement speaks about reality, it must be falsifiable: and in so far as it is not falsifiable, it does not speak about reality.
[Decimal currency is desirable because] by that means all calculations of interest, exchange, insurance, and the like are rendered much more simple and accurate, and, of course, more within the power of the great mass of people. Whenever such things require much labor, time, and reflection, the greater number who do…
Science is simply the classification of the common knowledge of the common people. It is bringing together the things we all know and putting them together so we can use them. This is creation and finds its analogy in Nature, where the elements are combined in certain ways to give us fruits or flowers or grain.
