Martin Rees shows the 6 numbers in his book Just Six Numbers:
nu (a ratio of the strength of electrical forces that hold atoms together compared to the force of gravity which is 10 to the 37th power). Were it a few zeros shorter, only a short-lived miniature universe could exist and there would be no time for biological evolution.
epsilon (how firmly the atomic nuclei bind together which is 0.004). If it were 0.006 or 0.008 we could not exist.
omega (amount of material in the universe). If this ratio were too high the universe would have collapsed long ago: if too low, galaxies or stars would not have formed.
lambda (force of cosmic "antigravity" discovered in 1998, which is a very small number)
Q (ratio of two fundamental energies, which is 1/100,000). If much larger the universe would be so violent that no stars or sun systems could survive.
delta (number of spatial dimensions in our universe). Life could not exist if this was 2 or 4.
