In English, the words “explore” and “exploit” come loaded with completely opposite connotations. But to a computer scientist, these words have much more specific and neutral meanings. Simply put, exploration is gathering information, and exploitation is using the information you have to get a known good result. [...]…
The principle of an opportunity cost does not at first glance seem hard to understand. If you spend half an hour noodling around on Twitter, when you would otherwise have been reading a book, the lost book-reading time is the opportunity cost of the tweeting. If you decide to buy a fancy belt for £100 instead of a…
irst, the “spotlight” of attention is how cognitive scientists tend to talk about perceptual attention. The things that are task-salient in my environment. How I select and interact with those, basically. Second, the “starlight.” If the spotlight is about doing things, the starlight is who I want to be, not just what…
The value of technology for transforming learning is lost if it is only used to digitize traditional materials (e.g. scanning worksheets makes them digital, but doesn't improve the learning experience). Instead, think about innovative approaches that allow students to engage with content differently. What does…
Well, the value of graduate school really depends on what you are studying and what you expect to get out of graduate school. I encourage young people to engage in the act of dynamic thinking. That means don't just apply the rules that worked in your field 20 years ago. Journalism is a great example. The media has…
Numerous studies have demonstrated that people generally give an excessive amount of value to confirmatory information, that is, to positive or supportive data. The "most likely reason for the excessive influence of confirmatory information is that it is easier to deal with cognitively" (Gilovich 1993). It is much…
"On the contrary. That was the time to begin all-out prevention of war. I played them one against the other. I helped each in turn. I offered them science, trade, education, scientific medicine. I made Terminus of more value to them as a flourishing world than as a military prize. It worked for thirty years." "Yes…
The Truth was the presumptuous name of the religion, the faith that lay behind the Shrievalty, the Cessoria, in a sense behind the Mercatoria itself. It arose from the belief that what appeared to be real life must in fact - according to some piously invoked statistical certitudes - be a simulation being run within…
...meaningful, transferable, and purposeful understanding: • Meaningful: The understanding is relevant to the students’ lives and needs. Students connect with the learning. • Transferable: The understanding fosters creative problem-solving and application. Students can apply their understanding to unique and out-of…
Pinker tiresomely rehearses the familiar triumphalism of science over religion: “the findings of science entail that the belief systems of all the world’s traditional religions and cultures ... are factually mistaken.” So they are, there on the page; but most of the belief systems of all the world’s traditional…
...older people in traditional societies have a huge significance that would never occur to us in our modern, literate societies, where our sources of information are books and the Internet. In contrast, in traditional societies without writing, older people are the repositories of information. It's their knowledge…
A challenge for society is to make use of those things that older people are better at doing. Some abilities, of course, decrease with age. Those include abilities at tasks requiring physical strength and stamina, ambition, and the power of novel reasoning in a circumscribed situation, such as figuring out the…
We have come to accept as inevitable a duo of coexisting lousy extremes. Sometimes information is supposedly free but people are subject to weird surveillance and influence, with insufficient commensurate rights. This is the familiar world of Google, Facebook, et al. It will not be a sustainable path as technology…
Ordinary people can help create new money by making promises. You constrain the future by making a plan, and a promise to keep to it. Money is created in response, because in making that promise you have created value. New money is created to represent that value. This is why it is possible for banks to fall apart…
In the digital universe, our personal history and its sense of narrative is succeeded by our social networking profile—a snapshot of the current moment. The information itself—our social graph of friends and likes—is a product being sold to market researchers in order to better predict and guide our futures. Using…
Such is simulation, insofar as it is opposed to representation. Representation stems from the principle of the equivalence of the sign and of the real (even if this equivalence is Utopian, it is a fundamental axiom). Simulation, on the contrary, stems from the Utopia of the principle of equivalence, from the radical…
Nobody knows more than a tiny fragment of science well enough to judge its validity and value at first hand. For the rest he has to rely on views accepted at second hand on the authority of a community of people accredited as scientists. But this accrediting depends in its turn on a complex organization. For each…
The value the world sets upon motives is often grossly unjust and inaccurate. Consider, for example, two of them: mere insatiable curiosity and the desire to do good. The latter is put high above the former, and yet it is the former that moves some of the greatest men the human race has yet produced: the scientific…
If a man walked in the woods for love of them half of each day, he is in danger of being regarded as a loafer, but if he spends his whole day as a speculator shearing of those woods and making earth bald before her time, he is estimated as an industrious and enterprising citizen—as if a town had no interest in forests…
The Johns Hopkins University certifies that John Wentworth Doe does not know anything but Biochemistry. Please pay no attention to any pronouncements he may make on any other subject, particularly when he joins with others of his kind to save the world from something or other. However, he worked hard for this degree…
