"At least half of humanity combs their hair every day, and yet almost no one pauses to think deeply about it."
Said Harvard scientist L. Mahadevan, who studies mathematics, physics, and organismic and evolutionary biology, quoted in "Scientists Unravel Mysteries Of Brushing Tangled Hair --- Researchers at Harvard, MIT use math, lab work to develop pain-free techniques" (Wall Street Journal).
The knotty hair puzzle reached Prof. Mahadevan's lab three years ago, as he was thinking about how birds build nests. His research led to the question of tangles, which also occur at the microscopic level in DNA helixes and in magnetic flux lines crisscrossing the cosmos....
"The unlinking of the homochiral helixes during this process can be quantified in terms of the Calugareanu-Fuller-White (CFW) theorem which states that Lk=Tw+Wr, where Link (Lk) quantifies the oriented crossing number of the filaments averaged over all projection directions" and so on....
As you know, if you've combed tangled hair with any competence at all, it doesn't work to start at the top and comb down. You work up from the bottom. Mahadevan, despite being a genius, couldn't comb his 5-year-old daughter's hair. But it percolated in his head for 20 years, and he ultimately did some sophisticated research (as you can see) that explains why you're going to want to start from the bottom and work your way up. Most of us observe and guess and do trial and error, but there's a place in this world for the genius, even if he can't comb a little girl's hair intuitively. We're told he has also studied "why Cheerios clump in a bowl of milk."
