By far the most numerous population will be chickens, with over 21 billion soldiers out of a total of ~30 billion birds. Not everyone in the current 7 billion human population will be able to battle against 3 chickens even with a pointy stick, but some of us may manage up to 5 of them. I guess we can win this one if we are prepared. Now if they act first and coordinate an attack at dawn while disabling communication networks (else we have 24h to react), we might be in trouble. We'd better strike first. Chicken for diner tonight it is !

Birds are in fact dinosaurs who genetically selfmodified and optimized themselves over millions of years. Unrelated question: Should i drive at the leftmost or at the rightmost edge of the bike path? Conventional wisdom would say right, so people can pass me on the left. But bike paths are usually so small that you can't really pass me on the left without being on the street. So they have to overtake me on the right anyways, by driving completely on the pedestrian way. If i drive at the left edge of the path however, it becomes pretty easy to overtake me on the right, possible while driving slightly on the pedestrian walkway. However, most people seem to favor driving on the rightmost edge of the path.

Or is it impossible to get a circle starting from a regular polygon? Is the surfacing of pi something elusive that haunts our quest for perfection or which accompanies our conceptual strengths? Should I ask this stupid question in the Math thread?

Anyways, you can achieve a circle as a specific limit of a series of regular polygons with increasing numbers of edges. It probably depends on the way you do your limitation whether you get a straight line instead. "A regular polygon with infinite vertices" is not very well defined in the same way that infinite/infinite is not well defined. You must clarify which limitation you are using to decide whether you get a circle or a straight line, though i assume that a straight line would require some weird limitation that completely breaks your polygon. However, the much more elegant way to describe a circle is simply as "All of the points which are at r distance from the central point" Pi isn't really a problem unless you feel the need to insist on writing it as a decimal or fraction. The number Pi is very well defined in a bunch of different ways. The problem here is not something that is fundamental to the number itself, but is instead similar to the way that a lot of people refuse to accept fractions as numbers, and believe that only things that are written as a decimal are actually numbers.

Does the circle arise if you fold the plane to connect the start of the polygon, but in 3d instead of 2d? Or is it impossible to get a circle starting from a regular polygon?

I feel like you are mixing up the calculation of pi with the defintion of a circle. Like most mathematical concepts, perfectly drawn circles don't exist real life anyways, they are simply a model of reality that best fits reality and are useful.

You get the straight line by taking a circle, fixing one point of the circle and pushing the center of the circle to infinity. (take the limit) one of the more interesting questions about PI is: why does it occur so often. From the calculation of a circumfence of a circle to a Gauss distribution is quite a leap.

The *only* real issue here is how the limit of an infinite rectangular domain represents a similar elliptical one. For that I refer you to the axiom of choice (Categorisation theories). Why does PI appear so often? It's simple. Take a number, say, 173. Ask yourself, "Self, how can I partition this quantity so that the coproduct of those pieces is maximized?" You guessed it! Divide it into 3's and a few 2's mixed in. Or, just solve the optimization equation (calculus) and arive at the optimal 'chunk' size of e=2.71828183 approximately. What is this thing? It is the ring balance of the number system. That means that you can transfer from one binary operation (+) to another (x) just by using logarithms based off this 'chunk'. Now how does that relate to pi? It's simple. Ask yourself another question. "Self? If e is such a great exponential base, then what is the logarithm base e of say, 1?" The answer is of course PI times the square root of 1. It's not coincidental. I'm not going to write a treatise here or anything, but I will say that this goes much deeper than any simple equation you could possibly learn, even in university (Don't bother with the countless simple series representations like cos(pi)+i*sin(pi)= 1. That's sooooo 16th century.) Short answer: PI is not the fundamental irrational, e is. And beneath e is the entire structure of numbers.

People should overtake on the left  even if it means going on the road. Cyclists on the pathwalk should be shot on sight.

It is incredibly annoying. If they just made the bike path half a meter wider, none of this would be a problem. (Which, granted, they seem to be doing for newer bike paths) But cities in Germany are car cities, so i guess we should be happy that we even get bike paths, even if they constantly degrade to a long line of bikes trapped behind a granny moving at a walking pace and slightly drifting from left to right. Half of this is just angry ranting about how much infrastructure cars get when compared to bikes. If a car street were even half as bad as some bikeways, people would be revolting in the streets. But it is completely fine for the bike path to be basically single lane and broken by tree roots, while there is a three lane perfectly new asphalted car street. Whole cities are built around cars, and half of the roadspace is wasted by parking cars.

Do you want to point to the whole complex of LieTheory and the importance of the exponential function within it?

Let's use starch as an example. A singular starch molecule can have thousands of glucose molecules chained to one another. Is this linkage between each glucose that important for how it interacts with its environment? It seems like the environment, which consists of molecules that interact with either starch or the components of which starch is made of (the glucose molecules alone) "know" that it's either 1 large molecules, or 1000 molecules and alter their behavior as such (for instance osmotic concentration drops and more liquid can enter when the 1000 molecules aren't formed as 1 entity) Does it have to do with entropy? Does it have to do with changes in physicochemical properties? I don't feel like 1 macromolecule composed of 1000 smaller ones should make itself and its environment behave that much different, but it seems like it does, so how does it work?
