“The objective . . .” of a 2018 research project from the Fashion Business School, London College of Fashion, and Dr Chris Gummer at Cider Solutions Ltd., Chilworth, UK, was “ . . . to assess the frequency and magnitude of combing forces on individual hairs against a hypothesis that fibres on a consumer’s head […]

The peak velocity of elbow joints during hair-combing activities (study)
If you comb your hair, you may have found yourself wondering how fast (in metres per second) your elbow moves as you do so. In which case, help is at hand – in the form of a recent paper published in the American Institute of Physics (AIP) Conference Proceedings. A research team from Kolej Poly-Tech […]
The Hairy Ball Theorem revisited – a newer, shorter, proof
Once proved, mathematical theorems* tend to stay proved. Nevertheless, they can sometimes still be improved – say, by making them shorter. Take, for example proofs for The Hairy Ball Theorem. Mathematician Henri Poincaré first drew attention to the Hairy Ball Theorem in 1885 with his treatise ‘Sur les courbes définies par les équations différentielles (III)’ Journal de […]
Forceful hair-combing measured
In 1966, hair combing made noise on both sides of the Atlantic – musical noise to the east, scientific to the west. In England, the Beatles released a song that said: “Woke up, got out of bed, dragged a comb across my head”. In America, William C Waggoner and George V Scott of the Colgate-Palmolive […]
