So last night, my subconscious projection of my brother talked to me about this cool observation he had
namely, if you spend more people (?) trying to transport stuff around, you only have logarithmic gains. However, he has "done the math", and it turns out the
distance grows linearly, so it's not that the people walk slower, but that they need to walk further.
This is of course not true, but I'm nonetheless impressed with my brain for coming up with it in my sleep because it's based on a real principle, and I've never thought about it before. Namely, suppose you have a hundred people walking on some narrow and curvy road, and for some reason they all have to walk in a horizontal line at all times. In this case, only the people in the middle can turn corners efficiently; the others have to walk further. best explained with a picture
i.e., just the connection between radius and circumference of the circle, but applied to a new context. Incorrectly applied since people could just not walk in a horizontal line, but nonetheless a logically coherent application. Also it's not logarithmic, of course.
And his proposed
solution was that we should basically parkour to make ways as straight as possible. There was a part where he made me jump over a car and then told me that, given the straight line I've now taken, I've only had an efficiency loss of 6% or something.
Not making this up.
