Mathematicians taking a physics class and being told they have to round things. That’s when the tears start flowing.

1?

Yup, similar to the square root of two and Euler's number.

These are numbers defined by their properties and not their exact values. In fact, we have imaginary numbers that don't have values and yet are still extremely useful because of their defined properties.

Try it when you find some physicist that cares about exact values. Or when you see pigs flying over your head, both are about as likely.

Now the engineers and/or scientists are crying

You don't need to, it's defined. (Lol). If you take a circle with a circumference of 1, then its circumference will be 1... I think I might have lost some braincells reading this.

I don't have to measure it. I stick under glass and define it as the standard which all other measurements are derived from.

I will be measuring it in meters. One. There you go.

Putting things in base 10 is also a definition. Digits aren't special.

That doesnt make a difference. You can find the exact circumference of a circle, you just cant express it in the decimal system as a number (thats why we have a symbol for it so you can still express the exact value)

I think it's because no matter how many corners you cut it's still an approximation of the ~~circumference~~ area. There's just an infinite amount of corners that sticks out

It's a fractal problem, even if you repeat the cutting until infinite, there are still a roughness with little triangles which you must add to Pi, there are no difference between image 4 and 5, the triangles are still there, smaller but more. But it's a nice illusion.

Because you never make a circle. You just make a polygon with a perimeter of four and an infinite number of sides as the number of sides approaches infinity.
