Simulation of Harvesting Asparagus: Mechanical Vs Manual

The Self-Mechanized Mind

From 1946 to 1953 ten conferences—the first nine held at the Beekman Hotel at 575 Park Avenue in New York, the last at the Nassau Inn in Princeton, New Jersey—brought together at regular intervals some of the greatest minds of the twentieth century. Sponsored by the Josiah Macy, Jr. Foundation, these meetings have since come to be known as the Macy Conferences. The mathematicians, logicians, en...

Self-propelled Leidenfrost droplets.

We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchetlike) topology. The pumping effect is observed when the liquid is in the Leidenfrost regime (the film-boiling regime), for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid ...
