The old saying “dig a hole to China” makes it sound as though all you need is a shovel, enough determination, and perhaps an extremely forgiving local government. In reality, digging all the way through Earth is vastly more complicated—and, on any practical scale, impossible. But the idea is a fascinating way to explore what lies beneath our feet. Read more

For a brief, remarkable period in the 1960s, the Indianapolis 500 seemed ready to be conquered by a technology that looked as though it belonged in an aircraft hangar rather than a race shop: the gas turbine. Read more

If you want a genuinely Fluxus-oriented walking tour of New York, the best approach is to treat it less like a museum tour and more like an archaeological expedition through Greenwich Village and SoHo. Fluxus was unusually embedded in apartments, lofts, churches, storefronts, streets, and improvised performance spaces—and many of those places still exist. Read more
The idea of mining asteroids has moved from science fiction toward serious commercial experimentation. Companies are now building spacecraft specifically designed to reach asteroids, while NASA and other space agencies have demonstrated that spacecraft can rendezvous with, land on, and even return material from asteroids. But there is an enormous difference between being able to reach an asteroid and being able to mine one profitably. Read more
Drilling a hole through thick glass is one of those jobs where patience matters more than brute force. Glass is hard, brittle, and unforgiving: excessive pressure, localized heat, or a poorly supported workpiece can turn a promising hole into a radial crack—or shatter the entire piece. Fortunately, with the right bit, cooling method, and technique, surprisingly clean holes can be made in substantial pieces of glass. Read more
In a typical episode of Star Trek, the phaser is much more than a futuristic pistol. It is the standard sidearm of Starfleet officers, a versatile tool that can be used to stun an opponent, incapacitate a dangerous creature, destroy an object, or, when necessary, deliver enormous destructive power. Its flexibility reflects one of the central ideas of Star Trek: advanced technology is supposed to give its users choices rather than simply making them more violent. Read more
Superheroes have traditionally gotten their powers from alien worlds, radioactive accidents, magic, or secret genetic mutations. But in the real world, a different kind of superhero is beginning to emerge: the technology-powered vigilante. These people don't fly because they were born on Krypton or possess mystical abilities. They fly, leap, run, see, and survive because engineers have built machines and materials that extend the capabilities of the human body. Read more

A couch is one of the largest and most frequently used pieces of furniture in a home, but buying one does not have to mean spending thousands of dollars. The online furniture market now offers an enormous selection of sofas, loveseats, sectionals, futons, and sleeper couches at surprisingly accessible prices. Major retailers such as IKEA, Walmart, and Wayfair offer numerous options below $500, while a budget of $800–$1,200 opens up considerably more choices. Read more
Selecting a measuring tool for professional drafting, engineering, woodworking, or architecture requires looking beyond a basic office ruler. Accuracy, material durability, unit readability, and edge straightness determine whether a tool delivers reliable, repeatable results over time. Read more
