The Other Grand Tour: 10 Stunning Space Stopovers

Cosmos is back, and Neil deGrasse Tyson is tooling around the universe in Carl Sagan’s Ship of the Imagination. But suppose someone handed you the proverbial keys? Where in space and/or time would you go?

If you don’t have a ready answer, never fear. I’ve put together an itinerary that can’t fail, whether your tastes run to science or sightseeing. Sure, we might have to break a few physical laws and grow a few extra senses along the way but, hey, it’s not called the Ship of Literal Reality, is it? So hang your fuzzy planets from the rearview and strap in for a star-spanning tour, a jaunt from the local neighborhood to the unreachably distant (and disproportionately dangerous) corners of the universe, en route to…

The Future: At the Corner of Close and Soon

Somehow the future we get is never quite the one we were promised. Then again, sometimes the very ideas wrapped in the pages of sci-fi and Popular Science are right under our noses, in disguise. After all, we have hand-held sensor-communicators and miraculous supermaterials – they just take the rather mundane form of carbon-fiber-wrapped smartphones.

Maybe our blindness arises from our physical and electronic architecture. Has exchanging Googie buildings for Google caused us to overlook the flying-car equivalents that fill our everyday lives, or soon will? Read on.

The Causation-Correlation Conflation

Leave a comment

Not equal signThe question of cause  has haunted science and philosophy from their earliest days, in part because humans are wired for pattern-matching and confirmation bias. For all our supposed rationality, we confuse coincidence with correlation and correlation with causality.

Consequently, scientists must carefully design and control their experiments to remove bias, circular reasoning, self-fulfilling prophecies and hidden variables. They must respect the requirements and limitations of their methods, draw from representative samples and not overstate their results. Sometimes, however, that’s easier said than done. Read on to hear about…

Like a Bridge Under Troubled Waters

Between the years of 1825 and 1843 , through floods and financial failures, Marc Isambard Brunel and his son dug a tunnel under London’s Thames River. Our ambitions have grown since then, but the technology we use still bears a striking resemblance to Brunel’s shipworm-inspired device.

In this article, I look at some of the worlds most breathtaking underwater tunnels and delve into how they were constructed.

The Art of the Bunt: Deconstructing Dickey’s “Tricky Hit”

Leave a comment

Bunting, says Bill James of Sabermetrics fame, is “the only play in baseball that both sides applaud.” But years ago, every player – even sluggers like Babe Ruth and Mickey Mantle – used bunting as a fundamental part of the game, and some coaches still prefer the bankable bunt when it comes to advancing runners, especially when a weak hitter steps to the plate.

Whatever your viewpoint, there’s little doubt that bunting is an art. Read on for the ins-and-outs of this venerable and controversial technique.
