Mathematician James Grime of the YouTube channel Numberphile has determined that 39 digits of pi—
3.14159265358979323846264338327950288420
—would suffice to calculate the circumference of the known universe to the width of a hydrogen atom. (That number is rounded, for those of you keeping track.)
JPL, on the other hand tracks Voyager 1 using pi rounded only to a measly 15 digits. https://www.jpl.nasa.gov/edu/news/20...e-really-need/
