Binstock: You seem fastidious about always giving people credit for their work. Kay: Well, I'm an old-fashioned guy. And I also happen to believe in history. The lack of interest, the disdain for history is what makes computing not-quite-a-field. Binstock: You once referred to computing as pop culture. Kay: It is…
Mrs. Lazarus has some experience with games such as this and decides to construct a blank environment (a planet without biomes) with a 10 × 10 grid, thereby creating a board with 100 squares. Before play, each student is given three different animals or plants (one with a broad tolerance for several different…
But she thought of Kuno as a baby, his birth, his removal to the public nurseries, her own visit to him there, his visits to her-visits which stopped when the Machine had assigned him a room on the other side of the earth.

The third technological revolution which I see coming is the expansion of life's habitat from Earth into the solar system and beyond. This revolution may take a little longer than the other two. Perhaps it may take as long as a hundred years from now. In charting a possible course for this revolution, I take as my…
Some of the first questions which come up in any practical discussion of space colonization are questions of economics. Suppose we go out and settle on a convenient asteroid with our little spaceship, what do we do when we get there? How do we make a living? What can we expect to export in order to pay for necessary…

The ancestors of modern North American bears evolved in Asia during the Pleistocene, wandering over to Alaska during several appearances of the Bering land bridge, between the Bering and Kamchatka Peninsulas. Advancing and receding glaciers, fueled by evaporating sea water, caused ocean levels to alternately drop and…
Human achievement is entirely a networking phenomenon. It is by putting brains together through the division of labor—through trade and specialization—that human society stumbled upon a way to raise the living standards, carrying capacity, technological virtuosity, and knowledge base of the species. We can see this in…

Most of the insects are small, precisely those that…
Now let's get a handle on what it really means to have a 1-in6,500 or a 1-in-13,000 chance of dying. It's as if you lived on an island in the South Pacific with a population of 650. You make your living by swimming around in the azure waters around your idyllic paradise and spearing fish for dinner. Yum, yum. About…
White people discovered the Galapagos Islands in 1535 when a Spanish ship came upon them after being blown off course by a storm.
