The shape of things to come

Imagine that the basic needs of everyone on Earth were taken care of. What would society be like? American futurist Jacque Fresco, who turned 98 last week, has spent his life thinking about this. Needs are at the root of capitalism. You have something that somebody else needs; that person has something that you need; you trade these things directly … >>

Standing up for science

The popular culture of today’s youth has focused on witches, wizards, hobbits and comic-book superheroes long enough. It’s time for science to reclaim its role as a source of inspiration.

The one thing America cannot do

While the Leoneans enjoy the convenience of the metric system, Americans continue to toil with inches, feet, yards, miles, ounces, pounds, gallons, acres, barrels and bushels. “I’ve been living here for … >>

I grew up during the golden age of science fiction. Every day, my friends and I would turn on the TV and see what the world would look like in the far-off 21st century, when we’d be in the prime of our lives. There would be colonies in space, encounters with aliens (both friendly and unfriendly), robots either doing our … >>
