As part of our effort to discern the Top Five Numbers of Key Importance within our little universe for The Big Board-little universe Project, we have begun to study the work of these two writers for Business Insider

Ben and Walter give us their very respectable listing of their Top 10:

1. Pi: 3.1415  Archimedes’ Constant
2. Euler’s Number: 2.7182 also known as e
3. The Golden Ratio: 1.6180
4. Planck’s Constant: 6.626068×10^-34 m² kg/s
5. Avogadro’s Constant: 6.0221515 x 10²³
6. Speed of Light: 186,282 miles per second or 299,792,458 meters per second
7. Gravitational Constant (G): 6.67300 x 10^-11 m³ kg^-1 s^-2
8. Boltzmann’s Constant: 1.380650 x 10²³ joule per kelvin
9. Imaginary Unit: i

10. Euler’s Identity: e^(i*pi) = -1
