Gamification Simultaneous Action Selection Mechanic
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 explains the rules. During each turn, one student is going to pick a card from the component deck and read it out loud. Then the other students select a card from their hand (...
Thin Slices of Joy
“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 of stepping from a hot room to an air-conditioned room, the moment of connection in receiving a text from an old friend. Although they last two or th...
Oliver Sacks on Focus in the Last Months of Life
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 care deeply about the Middle East, about global warming, about growing inequality, but these are no longer my business; they belong to the future. I rejoice when I meet gi...
How the Finance Industry Hurts the Economy
In perhaps the starkest illustration, economists from Harvard University and the University of Chicago wrote in a recent paper that every dollar a worker earns in a research field spills over to make the economy $5 better off. Every dollar a similar worker earns in finance comes with a drain, making the economy 60 cents worse off.

Orwell Notes Hitler's Rigidity of Mind
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 possible. For at that date Hitler was still respectable. He had crushed the German labour movement, and for that the property-owning classes were willing to forgive him almost...He notes that Hitler's ideas did not change at all over 15 years and that is a mark of madness.
Nature Doesn't Need Our Help to Destroy the Earth
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 land with lava, which could no more support life than big-city parking lots. It had in the past sent glaciers down from the North Pole to grind up major portions of Asia, Europe, a...Observation by Kurt Vonnegut that nature does a fine job of making the Earth uninhabitable regularly on its own.
Why Economists Will Continue to be Wrong
Carter had initially used arbitrary parameters in his perfect model to generate perfect data, but now, in order to assess his model in a realistic way, he threw those parameters out and used standard calibration techniques to match his perfect model to his perfect data. It was supposed to be a formality--he assumed, reasonably, that the process would simply produce the same parameters that had been used to produce the data in the first place. But it didn't. It turned out that there were many ...They make models based on past data, and when they fail to predict the future, they adjust them to match the new past data. The problem is that so many models will match the past data, there could be no end to the number of models they throw out.
Predictability and the Base Rate
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 terms of relative incidence. The second figure here is the base rate. Since it is just a number, obtained by the seemingly dull process of counting, it frequently gets overlooked wh...Keith Devlin explains why the accuracy of tests and measurments must take into account the base rate for the phenomenon.
What's Good for a Business Can be Bad for Society
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 cost or risk involved. For instance, a Siren Server might allow only those who would be cheap to insure through a doorway (to become insured) in order to make a supernat...Businesses that refuse to insure high-risk individuals leave the burden of those individuals on the whole community.
Check Your Privilege
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 you enter a minority space, you need to realize that this is their soapbox, not yours. Your privilege gives you many other soapboxes that you can take advantage of, so when p...From the article that inspired the use of this term in debate.
