Gravity is Energy

The laws of thermodynamics decree that each quantity of en^rgy has a characteristic quaUty called entropy associated with it. The entropy measures the degree of disorder associated with the energy. Energy must always flow in such a direction that the entropy increases. Thus, we can arrange the different forms of energy in an "order of merit," the highest form being the one with the least disorder or entropy. Energy of a higher form can be degraded into a lower form, but a lower form can never...

 Estimating Technical Progress

Overestimating the potential upside of every new sign of tech progress is as common as downplaying the downsides. It's easy to let our imaginations run wild with how any new development is going to change everything practically overnight. The unforeseen technical roadblocks that inevitably spring up are only one reason for this consistent miscalculation. Human nature is simply out of sync with the nature of technological development. We see progress as linear, a straight line of improvement. ...

 Space is Negative Energy

The great mystery at the heart of the Big Bang is to explain how an entire, fantastically enormous universe of space and energy can materiahse out of nothing. The secret lies in one of the strangest facts about our cosmos. The laws of physics demand the existence of something called "negative energy." To help you get your head around this weird'd but crucial concept, let me draw on a simple analogy Imagine a man wants to build a hill on a flat piece of land. The hill will represent the univ...

 Entropy in our Everyday Lives: Active Stability

Because things naturally move to disorder over time, we can position ourselves to create stability. There are two types of stability: active and passive. Consider a ship, which, if designed well, should be able to sail through a storm without intervention. This is passive stability. A fighter jet, in contrast, requires active stability. The plane can’t fly for more than a few seconds without having to adjust its wings. This adjustment happens so fast that it’s controlled by software. Ther...

 Mercurial Identities When Growing Up Online

From October 2015 to the present day, I have lived approximately 168 different lives on the internet. I was Eve the Nobody before I was Eve the Sex Writer before I was Eve the Comedian before I was Eve the Depressed Girl before I was Eve the Drunk before I was Eve the Feminist before I was Eve the Tech Blogger before I was Eve the Democratic Socialist before I was Eve the Hater before I was Eve the Teetotaler before I was Eve the Professional Politics Writer before I was Eve the Sword Girl be...

 Rules are the Persistent Identity of a Game Across Cultur...

There are at least two senses in which the RULES schemas offer a "formal" way of looking at games. First, the term formal is used in the sense of "form": rules constitute the inner form or organization of games. In other words, rules are the inner, essential structures that constitute the real-world objects known as games. For example, consider two games of Go that differ in a variety of ways. They might differ in terms of: Material: one version is played with stones on a wooden board; the o...

 The Boundaries of a Game Versus Boundaries of Other Kinds...

What does it mean to say that games take place within set boundaries established by the act of play? Is this really true? Is there really such a distinct boundary? In fact there is. Compare, for example, the informal play of a toy with the more formal play of a game. A child approaching a doll, for example, can slowly and gradually enter into a play relationship with the doll. The child might look at the doll from across the room and shoot it a playful glance. Later, the child might pick it u...

 With Educational Games, Even if the Kids Don't Get It, Yo...

...where does probability theory come from? What is its source? Clearly, like many other sciences, like arithmetic itself, probability theory emerged from observations of certain real-world phenomena, namely, random, unpredictable phenomena. And it is exactly these kinds of observations—fundamental to the formation of science—which are worth making together with kids. Well, not all of them, of course, just the simplest ones. Besides, kids are making them on their own; e.g., when they play...

 Successful Prediction

Successful prediction is the revenge of the nerds. Superforecasters are intelligent but not necessarily brilliant, falling just in the top fifth of the population. They are highly numerate, not in the sense of being math whizzes but in the sense of comfortably thinking in guesstimates. They have personality traits that psychologists call “openness to experience” (intellectual curiosity and a taste for variety), “need for cognition” (pleasure taken in intellectual activity), and “int...

 Fluid Intelligence has Made the Most Gains

So which kinds of intellectual performance have been pushed upward by the better environments of recent decades? Surprisingly, the steepest gains have not been found in the concrete skills that are directly taught in school, such as general knowledge, arithmetic, and vocabulary. They have been found in the abstract, fluid kinds of intelligence, the ones tapped by similarity questions (“What do an hour and a year have in common?”), analogies (“BIRD is to EGG as TREE is to what?”), and ...
