Concave Growth Function
This is for my homies taking calculus.
Here’s a real-life example of a concave function. Around minute 35, they say that as an animal grows in size, each cell requires less energy — so its total energy consumption is concave as a function of size.
Yup, this is the complicated way to say it — on purpose. Listen to the podcast to hear it in terms of elephants and mice.
I think there is an even more complicated way to put it — maybe it’s called the “Euler characteristic” or something, essentially it’s that
so that different functions with a different value for n scale in different ways.
If you can put the symbols together with the real-life meaning, it will pay off in terms of insight. You can see something and think to yourself “hey, that’s convex!” And you can also imagine the phenomenon with a different value of n — i.e. different scaling properties.
