Goodbye hair knots, at Harvard found an algorithm to untie them. And at MIT you are working on a robot

A team of researchers from Harvard University in the United States led by Professor Mahadevan has found the solution to a problem that exasperates many, sometimes to tears: untying the knots in the hair. “You start at the bottom with a short stroke. As you go up, the shots get longer and longer,” explained a member of the team who finally solved the puzzle and published the discovery in the scientific journal. Soft Matter.
