Never thought I'd use: "Wetness per second," as a measuring unit.

There's a lot of complications to this problem. You assume that rain falls directly down, but most rain is accompanied by wind. Now, rain hitting you side is a function of time, distance, and speed (if you exactly match the speed of the wind, no rain will hit you from the side). Turns out, the best strategy into the wind is maximize speed, and with the wind you want to be a bit faster than the wind.

That was the longest "running is better" I've ever heard

many scientists believe using an umbrella might actually help

I was fearing he would say last minute: "so the best solution is to use an umbrella" after all the math he explained XD

This is amazing, I’ve had this exact theory for ages now, but always felt like I was making stuff up when I was telling other people. Until today. Seeing it actually be proven true feels so validating.

Don't forget that's assuming constant rainfall. I was in a situation recently where the rain was getting stronger and stronger, so moving fast would have helped me avoid the heavier rain that I took from walking slowly.

Let's appreciate those who invented umbrellas otherwise this could be the hardest physics word problem

As a Dark Souls enjoyer I can advise you to learn Rain's pattern and dodge/roll every attack, it also has a charging attack which is called "The Lightning strike" that will stagger you and take a great deal of hp, so you should hide all magnetic/iron equipment to avoid this attack.

I've honestly wondered about this my whole life, but couldn't figure out the maths behind it. Moving upward into the rain is a great visual.

Looks like youtube recommendation brought us all together again

Update: we actually just can’t go out anymore

i think there's another factor that isn't mentioned here. when you stand still, your average cross sectional area (where raindrops will hit you from the top) is the minimum. but when you run, you lean forward, which increases your cross sectional area and expose your back and legs to rain too.

"9 out of 10 scientists recommend this umbrella"

if i walk backwards would i get more dry?

the best way is to dodge the rain drops

Grandparents : i dont have the tooth for maths or physics so i carry an umbrella everyday.
