The current push to bring digital games into school is, strictly speaking, not the first, nor even the second time that educators have pushed for individualized instruction via machines. But it is decidedly the most nuanced, humanistic, and thoughtful. The first actually took place in the 1950s and early 1960s, when a…
As a matter of fact it was not until 1940 that Selkovski invented the purple alga Porpbyrococcus fixator which was to have so great an effect on the world's history. . . . Porpbyrococcus is an enormously efficient nitrogen-fixer and will grow in almost any climate where there are water and traces of potash and…
While individuals get our empathy and sympathy, institutions seldom do. The "we're in this together" spirit of films from the 1930s, 1940s and 1950s later gave way to a reflex shared by left and right, that villainy is associated with organization.

This means unemployment due to our discovery of means of economising the use of labour outrunning the pace at which we can…
A bracingly cold glass of water was thrown on this Eisenhoweresque perception by famed sociologist E.E. LeMasters. In 1957, he published a research paper showing that 83 percent of new parents experienced a moderate to severe crisis in the marriage during the transition to parenthood. These parents became increasingly…
Ann Druyan and I come from families that knew grinding poverty. But our parents were passionate readers. One of our grandmothers learned to read because her father, a subsistence farmer, traded a sack of onions to an itinerant teacher. She read for the next hundred years. Our parents had personal hygiene and the germ…
