Planets ~ Springs | The Newton-Hooke Duality and Beyond
Everything’s a spring!? When I’m in a cheeky mood, I like to tease first-year physics students by telling them that for physicists everything is a spring1 or a (potentially infinite) co…

Gabriel's Horn is a solid you get by rotating the hyperbola y=1/x (with x>1) about the x-axis. Having finite volume (π) and infinite(!) surface area, it leads to the apparent paradox: "You can fill it with paint, but you cannot coat it."

Consider the function f(x) = 1 / ( ⌊x⌋ + 1 − {x} ) and the sequence of numbers 0, f(0), −f(0), f(f(0)), −f(f(0)), f(f(f(0))), −f(f(f(0))), ... Congratulations, you've just listed every rational number exactly once!

Everyone knows that all circles are similar. But did you know that all parabolas are similar? The ratio of the red arc and the blue focal segment is √2 + ln(1+√2) = 2.29558... for every parabola. This is the universal parabolic constant, the “π of parabolas”.
