Alloys that can return to their original structure after being deformed have a so-called shape memory. This phenomenon and the resulting forces are used in many mechanical actuating systems, for ...

For the study the researchers recruited 35 dogs who were trained to fetch a target object from a set of distractors. During testing, the dogs were presented with two choices: one matching the target ...

Graduate students at the University of Tokyo have outdone themselves and are changing the way we look at drones with their newest invention. They created a group of futuristic-looking drone prototypes ...

Mathematicians are “reinventing the wheel” by giving it a new shape. Their newly imagined wheel looks like a many-dimensional guitar pick, and it could theoretically roll in ways beyond our ...

When most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier-sounding rhombus or trapezoid. But to mathematicians, shapes encompass a vast universe of surprising ...

Over the last two years, mathematicians have identified the best versions of a child’s playroom’s worth of shapes. These results occupy a quirky corner of math and, fittingly, have been produced by ...

Years ago I would have melted lead and poured it into the object to be weighted, maybe used a form to cast it first if there was danger of the object melting and letting liquid lead run everywhere.
