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

For most of human history, entering a cave was less an act of exploration than an encounter with the unknown. Caves were places of shelter, burial, ritual, mining, water collection, and legend. Their passages disappeared into darkness, their depths were impossible to judge, and a wrong turn could mean becoming lost only a few hundred yards from daylight. Read more

Few microprocessor architectures have had as long, influential, and surprisingly coherent a life as Motorola’s 68000 family. Introduced in 1979, the M68k architecture began as an ambitious 16/32-bit CISC design and evolved through increasingly sophisticated memory management, caches, pipelining, floating-point hardware, and finally superscalar execution.

Slime is a soft, highly deformable material that behaves somewhere between a liquid and a solid. Its unusual properties come from a polymer network: long molecules become lightly linked together, allowing the material to stretch and flow while still holding its shape. 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

Kickball is one of those games that seems as though it has always existed. Its rules are simple, its equipment is inexpensive, and it can be played almost anywhere with a ball, a few bases, and a group of people. For generations of American children, kickball has been a staple of schoolyards, playgrounds, summer camps, and neighborhood games. Yet the sport has a surprisingly long history, with roots in early twentieth-century physical education and connections to baseball, softball, and older kicking games. Read more

Few dog sports combine athleticism, precision, speed, and interspecies teamwork quite like competitive dog agility. In an agility competition, a dog races through a course of jumps, tunnels, weave poles, ramps, and other obstacles while responding to signals from its handler. The goal sounds simple: complete the course correctly and as quickly as possible. In practice, agility demands an extraordinary level of communication between dog and human. Read more

Jigsaw puzzles seem simple: a picture is divided into pieces, and the solver’s task is to put those pieces back together. Yet beneath this familiar pastime lies a surprisingly rich field of ideas involving perception, memory, mathematics, psychology, and even philosophy. Theories of jigsaw puzzles attempt to explain not only how puzzles can be constructed, but also why solving them is satisfying and how the human mind recognizes where individual pieces belong.

Drawing a perfect square without a ruler with measurement markings may seem like a challenge, but it is a classic construction problem in Euclidean geometry. With only a compass and an unmarked straightedge, you can construct a square of any chosen side length. The secret is to construct a 90-degree angle and then use the compass to reproduce the same length on the other sides. Read more
