While researching my soon-to-be-released biography on John Horton Conway, an iconoclastic and very influential mathematician at Princeton, I organized a research trip to his native England. We visited with Conway’s elder sister, Joan, in Liverpool, and convened a reunion at his alma mater, Cambridge. We met there with a few of his “sum chums,” his co-authors […]

“Add little to little and there will be a big pile.” —Ovid When we build complex technologies, despite our best efforts and our desire for clean logic, they often end up being far messier than we intend. They often end up kluges: inelegant solutions that work just well enough. And a reason they end up being […]

The National Institutes of Health’s “Human Connectome Project” aims to elucidate the architecture of nerve fibers in the brain, as illustrated here. Patric Hagmann, Department of Radiology, University Hospital Lausanne (CHUV), Switzerland In 2005 neuroscientist Henry Markram embarked on a mission to create a supercomputer simulation of the human brain, known as the Blue Brain […]

If you ask Anthony Weiner, digital records—especially those on the Internet—can seem impossibly hard to get rid of. When a picture or document is reduced to a series of 1s and 0s, it becomes transmissible, reproducible, downloadable, and storable. You can’t burn digital books, and ideas like cloud computing make it possible to back up […]

Let’s consider the fear that once surrounded another powerful technology: recombinant DNA.

In the early 1950s, the U.S. Air Force Supply Depot in Ohio was looking for a faster way to store and fetch information from its sizable inventory. They had 50,000 items in their records and wanted instant access to each one of them. The dominant storage technologies of the time—punch cards, magnetic tape and magnetic […]

A statue of Alan Turing by sculptor Stephen Kettle made entirely of pieces of slate. The statue depicts Turing working on an Enigma machine, which the Nazis used to encode messages, and is located at Bletchley Park, the British-government site where Turing and colleagues did their code-breaking.

Never mind tablet computers. Wait till you see bubbles and slime mold.

We may not have realized it at the time, but during the 1990s, Hollywood movies were infiltrated by a new presence that outshined even the biggest screen stars: Images created on computers became the main draws for movies like Jurassic Park, Toy Story, The Matrix, and Star Wars Episode I: The Phantom Menace. Since then, […]
