What does a number 84600 represent?
The number of seconds in one day
The number of atoms in 1 dl of water
The number of computers in London
The number of stars in Milky way galaxy
The number of stars in our galaxy is around 200 billion and there are around 3,3 billion quadrillion atoms (3,3*10^24) in 1 dl of water. If you consider the population of London ( +/- 9million), you can figure out, there should be a similar number of computers there, or at least more than a million. The number of seconds in one day is 60*60*24, which is 84600.
