Today’s Spotlight features an image, by Felice Frankel, of a square-shaped "intruder" plunging through sand-like material.
For those of you who take sandcastle building very seriously, listen up: MIT engineers now say you can trust a very simple equation to calculate the force required to push a shovel — and any other “intruder”— through sand. The team also found that the same concept, known as the resistive force theory, can generate useful equations for cohesive materials like muds.
