I had the most satisfying Eureka experience of my career while attempting to teach flight instructors that praise is more effective than punishment for promoting skill-learning. When I had finished my enthusiastic speech, one of the most seasoned instructors in the audience raised his hand and made his own short…
There’s a tendency in all of us to gather useful stuff and feel good about it. To collect is a reward in itself. As knowledge workers, we’re inclined to look for the next groundbreaking thought, for intellectual stimulation: we pile up promising books and articles, and we store half the internet as bookmarks, just so…
The changes in the conditions of human life during the last twenty or thirty thousand years have been mainly brought about by the acceleration of invention through increasing co-operation and the release of material and social power. There have been no doubt climatic and geographical changes, but their share has been…
On a previous assessment, Mrs. Tabor asked her students three different questions to assess their science-centered critical thinking. Based on the answers, she gives each student a chip with a different color and value (much like the suns in Ra). Students who demonstrated an “average” level of critical-thinking skills…
A duct-less split can produce the exact amount of energy needed to temper an envelope. When I first read this sentence, my mind started to try to make connections to envelopes and wondered if tempering had something to do with getting or keeping the glue on the flap. If you are an engineer, you probably know that the…
In Munich he walked. The air was warm and clean; it cleared some of the fumes from his head. He walked the brightly lighted slidewalks, adding his own pace to their ten-miles-per-hour speed. It occurred to him then that every city in the world had slidewalks, and that they all moved at ten miles per hour. The thought…
The game is called who’s the best at flipping coins. It’s pretty simple. You flip a bunch of coins and whoever gets the most heads wins. To make this a little more interesting, though, not everybody has the same number of coins. Some people—Team Small—have only ten coins, while the members of Team Big have a hundred…
Experimentation is something done by everyone all the time. Babies experiment with what might be good to put in their mouths. Toddlers experiment with various behaviors to see what they can get away with. Teenagers experiment with sex, drugs, and rock and roll. But because people don’t really see these things as…
Not long ago, a young boy handed me an envelope containing 300 euros. He said he wanted it to be used to help the orphans at our ashram. I asked him to keep the money, which he had won in a music competition, but he refused. Two weeks later, his little sister came to me with an envelope containing her ice-cream pocket…
Surveillance serves not just as a legal and historical record but as a record of rep: proof that you’ve done what you say you’ve done. You bark, and anyone on the mesh can search to see if you also bite. It’s the foundation of the reputation economy. It’s not just video, of course, but surveillance of all types…
It is India that gave us the ingenious method of expressing all numbers by means of ten symbols, each symbol receiving a value of position as well as an absolute value; a profound and important idea which appears so simple to us now that we ignore its true merit. But its very simplicity and the great ease which it has…
I value science—none can prize it more, It gives ten thousand motives to adore; Be it religious, as it ought to be, The heart humbles, and it bows the knee.
Discovery always carries an honorific connotation. It is the stamp of approval on a finding of lasting value. Many laws and theories have come and gone in the history of science, but they are not spoken of as discoveries. Kepler is said to have discovered the laws of planetary motion named after him, but no the many…
The determination of the value of an item must not be based on its price, but rather on the utility it yields. The price of the item is dependent only on the thing itself and is equal for everyone; the utility, however, is dependent on the particular circumstances of the person making the estimate. Thus there is no…
Man may be excused for feeling some pride at having risen, though not through his own exertions, to the very summit of the organic scale; and the fact of his having thus risen, instead of having been aboriginally placed there, may give him hopes for a still higher destiny in the distant future. But we are not here…
[P]olitical and social and scientific values … should be correlated in some relation of movement that could be expressed in mathematics, nor did one care in the least that all the world said it could not be done, or that one knew not enough mathematics even to figure a formula beyond the schoolboy s=(1/2)gt2. If…
Here are a few second-order instinctual drives some people seem to have that are all opportunities for memes to take advantage of: - Belonging. Humans are gregarious-that is, they like company. There are any number of evolutionary reasons for the existence of this drive, including safety in numbers, economies of…
An early classic experiment by the Nobel Prize-winning embryologist Roger Sperry illustrates the principle perfectly. Sperry and a colleague took a tadpole and removed a tiny square of skin from the back. They removed another square, the same size, from the belly. They then regrafted the two squares, but each in the…
As a member or supporter of the Coffee Party, I pledge to conduct myself in a way that is civil, honest, and respectful toward people with whom I disagree. I value people from different cultures, I value people with different ideas, and I value and cherish the democratic process.
The first chart of the Gulf Stream was prepared about 1769 under the direction of Benjamin Franklin while he was Deputy Postmaster General of the Colonies. The Board of Customs in Boston had complained that the mail packets coming from England took two weeks longer to make the westward crossing that did the Rhode…
