(Reuters) - British scientists said on Friday that a "Rapunzel Number" may have helped them to crack a problem that has perplexed humanity since Leonardo da Vinci pondered it 500 years ago.
Scientists from the University of Cambridge and the University of Warwick said they had devised a "Ponytail Shape Equation," which when calculated using the Rapunzel Number and a measure of the curliness of hair can be used to predict the shape of any ponytail.
