I sound awful saying it but I think it can be like that. I see a lot of people in unstimulating relationships. And not just boyfriend-girlfriend relationships. They find themselves in stagnant friendships. If people were a little less scared of ending things they’d get more out of life… You meet the right person at the right time and they fulfill a certain something in your life. You fulfill something in theirs. But there’s a time limit to that.
The letter e as the base for natural logarithms was born 25 Nov 1731 in a letter from Euler to Goldbach. e was discovered (but not named) in 1683 by Jacob Bernoulli, as the limit of (1+1/n)^n as n tends to infinity. Prior to its discovery, the nameless constant e had been lurking around the embryo of the logarithm for many years.
