…and maybe of all time, at least in quantitative terms. In the New York Times Magazine, 4/10/2016:
An article on March 20 about wave piloting in the Marshall Islands misstated the number of possible paths that could be navigated without instruments among the 34 islands and atolls of the Marshall Islands. It is 561, not a trillion trillion.
A trillion trillion is presumably 1024, and 561 is 5.61 x 102, so the original number was off by a factor of about 1.78 x 1022, which is more than a thousand times greater than the estimated number of grains of sand in all the beaches and deserts of planet earth.
