 Programming as a Way of Thinking

Running programs is the whole point of programming, of course, but there is more to it. The ability to execute code makes programming a tool for thinking and exploring. When we express ideas as programs, we make them testable; when we debug programs, we are also debugging our brains.

 Schemata

Not only does background knowledge grow in the brains of our students through their experiences, but the vocabulary words that are stored as a result of such experiences provide avenues to comprehend the curriculum from the text, as well as lecture and discussion. We can look at the work of Piaget (1970), who concluded that we organize information in our brains in the form of a schema, a representation of concepts, ideas, and actions that are related. Schemata (the plural of schema) are form...

 Brains Must Feel Safe for Education

The brain’s main job is prioritizing information relevant to our survival. Anything that suggests the possibility of danger, whether real or imagined, becomes a higher priority than anything else that is going on at that moment. This data is processed first, shifting our attention from cognitive processes down to the faster-acting limbic system, while more complex cerebral operations shut down. Survival always overrides problem-solving, analyzing, remembering, pattern-detection and other ra...

 Martin Rees: We'll Never Hit Barriers To Scientific Under...

We humans haven't changed much since our remote ancestors roamed the African savannah. Our brains evolved to cope with the human-scale environment. So it is surely remarkable that we can make sense of phenomena that confound everyday intuition: in particular, the minuscule atoms we're made of, and the vast cosmos that surrounds us. Nonetheless—and here I'm sticking my neck out—maybe some aspects of reality are intrinsically beyond us, in that their comprehension would require some post-h...

 The Cosmic Perspective

The cosmic perspective comes from the frontiers of science, yet it's not solely the province of the scientist. The cosmic perspective belongs to everyone. The cosmic perspective is humble. The cosmic perspective is spiritual—even redemptive—but not religious. The cosmic perspective enables us to grasp, in the same thought, the large and the small. The cosmic perspective opens our minds to extraordinary ideas but does not leave them so open that our brains spill out, making us suscepti...

 Teaching as Natural Selection

Teaching is commonly associated with instruction, yet in evolution, immunology, and neuroscience, instructional theories are largely defunct. We propose a co-immunity theory of teaching, where attempts by a teacher to alter student neuronal structure to accommodate cultural ideas and practices is sort of a reverse to the function of the immune system, which exists to preserve the physical self, while teaching episodes are designed to alter the mental self. This is a theory of teaching that ...

 Factions in the Artilect War

I predict that humanity will split into three major philosophical, ideological, political groups, which I label as follows. –The Cosmists (based on the word “cosmos”) will be in favor of building these godlike machines (the artilects), who would be immortal, think a million times faster than humans, have unlimited memory, go anywhere, do anything and take any shape. The Cosmists would take a quasi-religious view that they are god builders. Privately, I am a Cosmist, but publicly, I hav...

 The Moving Goalposts of Success

The absence of disease is not health. Here's how we get to health: We need to reverse the formula for happiness and success. In the last three years, I've traveled to 45 different countries, working with schools and companies in the midst of an economic downturn. And what I found is that most companies and schools follow a formula for success, which is this: If I work harder, I'll be more successful. And if I'm more successful, then I'll be happier. That undergirds most of our parenting style...

 The Prefontal Cortex

Executive functions take place in the prefrontal cortex of the brain. I love the term that Stanislas Dehaene uses to describe this part of the brain—a global neuronal workspace. The prefrontal cortex is responsible for the ability to exchange information across the high-level areas of the brain, Dehaene says, so that our behavior can be guided by our accumulated knowledge. That’s the beauty and the purpose of executive functions: they enable us to control ourselves, to reflect deeply, and...

 You Can't Predict What You Are Going to Do

In the physical world, the only way to learn tomorrow’s weather in detail is to wait twenty-four hours and see, even if nothing is random at all. The universe is computing tomorrow’s weather as rapidly and as efficiently as possible; any smaller model is inaccurate, and the smallest error is amplified into large effects. At a personal level, even if the world is as deterministic as a computer program, you still can’t predict what you’re going to do. This is because your prediction me...
