We tie our shoes, we put on neckties, we wrestle with power cords. Yet despite deep familiarity with knots, most people cannot tell a weak knot from a strong one by looking at them, Johns Hopkins ...

The researchers showed participants four knots that are physically similar but have a hierarchy of strength. People were asked to look at the knots, two at a time, and point to the strongest one. The ...

We are deeply intuitively familiar with our everyday physical world, so it was perhaps a bit of a surprise when researchers discovered a blind spot in our intuitive physical reasoning: it seems humans ...

Researchers have unearthed a robust physics-based mechanism that dictates the sliding strength, or resistance to slippage, of the most common type of surgical knot. In particular, they have found that ...
