Never heard it stated that way. Can you elaborate on "the smallest possible distance is Plank's length"? Is that the smallest observable distance?
If you have some time to spare, watch this talk "The astonishing simplicity of everything" by Neil Turok. He explains all this so beautifully. https://www.youtube.com/watch?v=f1x9lgX8GaE

Physics? Numerical analysis is Mathematics. It's still active and very important, e.g., in solving PDEs using the finite element method.
Mathematics? The people trying to find solutions of an equation by solving them? Mathematicians is a weird education I hardly understand. The last PhD I met from Mc Gill university ignored the existence of non euclidean geometry. His excuse? He was on formal proof. I am sorry, I have a hard time with people that never were challenged to make equations spit their solutions in order to make something actually work in t…
Wat?
i wonder if interest in measuring error of previous calculations is what encouraged this direction of computational rigor respecting accuracy encourages a self awareness with an almost conscious stead ignorant error i am always intrigued when it is discussed how a calculation began and the error of the initial values the first known attempt at measuring the speed of light(o) had an ignorant error of ~26% the first kn…
That should be 0.04% not 0.0004%, no? You need to multiply by 100 for percent?
add human error to the list
If you know the diameter of the observable Universe and you want to calculate its circumference with the accuracy of the diameter of a proton, the number of digits of pi that you need is 43.
Would have been so much better if that answer was 42.
