It raining should i run or walk

Reflections on Life in Quarantine. How Do Clouds Form? I can't believe scientists have time to discuss this! Who pays them for this! That's what science is all about. That's what scientists do. Orthogonal projected area of ellipsoid figshare.

Wet is wet no matter the coverage. Walking with a big umbrella is always best,.. Be prepared! Boy Scout's rule. Sign up for our email newsletter by entering your email address. In , another Italian researcher asserted in the journal that changing strategies did not make a substantial difference. In , a textile expert and a physicist used the same publication to suggest that an optimal speed existed, depending on the wind direction.

What complicates the question is the human shape; for simplicity, previous attempts to crack the thorny problem assumed people to be thin sheets or upright, rectangular boxes. When Prof Bocci considered a more general case - likely to be the case you would face in the rain - he found that the answer may depend on an individual's height-to-breadth ratio as well as wind direction and raindrop size.

In this case, regardless of the rate at which the rain is falling, your best option is to move as fast as you can to minimise your time spent in the rain. Well, what if the rain is coming down towards you at an angle due to the wind?

An important concept in this problem is the rain region. This region contains the initial positions of all raindrops that will hit you at some future time. What if the rain is coming from behind you? Walking means you're going to spend more time getting wet, and running means you'll spend less time getting wet, but logic suggests that when you run, you'll also get hit by more raindrops from the side. So which option is better? Based on a study published in the European Journal of Physics in , Henry Reich explains in the episode of MinutePhysics above , as you walk out of the way of one raindrop, you're moving into the path of another one.

This means the amount of rain that's hitting the top of you is constant, regardless of how fast you're going.
