I can’t be arsed to check but I think it’s 2 pi which is useful when dealing with sine waves.

What’s the significance of that number? It’s less than 0.1 away from tau, but somehow I doubt that’s it…

2 pi is tau, which is what I said it’s less than 0.1 away from, but still not equal to.

For me, it was this video. It came out shortly after I graduated high school, and though I was pretty good at maths, I struggled to really conceptualise the fundamental intuition behind trigonometric functions and the (polar) complex plane. Instead, I was relying on brute memorisation of the unit triangles. Learning about tau and how it relates just instantly caused everything to click with me.

I assumed the number is not significant, figure it’s just supposed to mock the idea that physicists don’t know what tolerances are.

An experimental physicist should know as far as I know meanwhile a real (theoretical) physicist would probably not even touch numbers that have those scary decimals.
