Provide an E-Number in miles and kilometer
Sir Arthur Eddington (1882-1944) is known for his work on Einstein’s Theory of Relativity, but also loved cycling. He devised a measure of a cyclist’s long distance riding achievements called the “Eddington Number.” It is defined as the largest integer E, where you have cycled at least E miles on at least E days. For example an E of 83 means that you have ridden 83 miles or more on 83 or more days. There could also be a metric E-Number which would be kilometer and days. An E-Number of 100 in miles is much different that an 100 E -Number in Km.
