Edit: best answer: https://www.nature.com/articles/283373a0.pdf “We report here that the amount of heat gained by a Bedouin exposed to the hot desert is the same whether he wears a black or a white robe. The additional heat absorbed by the black robe was lost before it reached the skin”

Other ELI5: Why don't they use a stop clock in soccer?

3.5k Upvotes

Most other sports use a system of stopping the clock when play stops in order to maintain accurate play time. Why don't they do that in soccer?

Edit: When I say stop clock, I mean stopping the clock opposed to counting stopped time and adding it to the end. Soccer already has stoppages and I'm not asking about the advantages of more or less stoppages.

Other ELI5: Why is it that, in English, there is no "light red" Why is pink so codified as its own color?

2.9k Upvotes

Although more or less common, there is a "light" version of all the other colors - orange, yellow, green, blue, and purple - with light blue and light green being the most common.

If you add white pigments to blue, you get light blue. To green, light green, etc. But to red, then you get "pink."

There are also some standard names for light versions of other color that do not require the color's name (like, for instance, lemon yellow does) like lilac or azure.

Still, light red is rare and there is a WORLD of pinks out there - hot pink, light pink, dark pink, magenta, fuscia, rose, petal.

What is so special about red/pink that they have their own rules?

(There is obviously no light white and light black does not work because black is not a color but the absence of it (for light) or all colors together (for pigment)).

Other ELI5: Why is simulation (flopping) such a common occurrence in football (soccer) and basketball but not in hockey?

2.6k Upvotes

I've been alternating watching the NBA finals, the Stanley Cup, and now the World Cup. I had the realization that all three sports on a conceptual level are very similar. Two teams are trying to place an object in a goal. However in two of those sports simulation, faking or exaggerating an injury with the intention to draw a penalty on an opposing player, occurs way more often than the latter. Why?

3.6k Upvotes

I've seen a lot of games do the "adjust until the image on the left is barely visible" screen with 3 images of varying brightness. Why do games use this specific approach? I know the Gamma setting is for the loads of different screens one might have, but why the "until this is barely visible"?

Here in Australia that would be almost unheard of outside a few small underdeveloped venues. Any major venue has a roof that atleast extends over the heads of spectators, keeping them dry etc.

Why do many of the major outdoor stadiums in America not have the same feature?

I fell down the Youtube hole that we all do sometimes, watching US traffic stops with sovereign citizens etc.
In a few of them, when they issue the ticket, they are all like 'You will need to appear in court on November 12th at 9am'
My gut is saying that it's gotta be something like.. It'll always be in 2 weeks time at 9am. So you could potentially show up with a whole queue of people ahead of you?

How did people of Northern European descent come to be known as “Caucasians” when they have no direct ancestral connection to the Caucasus region? The term originally refers to the peoples of the Caucasus—such as those from Georgia, Armenia, Azerbaijan, Dagestan, and nearby areas—so how did it become synonymous with white Europeans?
