Recently, a Japanese television program has done such experiments, calculated the "safest skirt length." How long does it take you to get the stairs? First of all, experts are based on the principles of the principle and the perspective of things such as illustrations, and then they seriously asked the experts to the field measurement calculations. However, the formulas they say are beyond my comprehension, so please forgive me for the bad math.

Basically, the "safest skirt length" is the "staircase equation" and the "show the underpants equation" that they figured out. Hip/2x3.14= skirt radius skirt length =tan[stair angle]x skirt radius +25 Looming is called absolute field

I completely do not understand what they are doing, where the science of good people to jump out to explain it? All in all, the safest length of the whole pile of stuff is 35cm. It's one of those people who can't see you in the back of the stairs. The length of your trousers.
