The name "Lambert" seems to be the source of some strange coincidences in my life. Here are some anecdotal evidence:
My father owned a VW beetle, whose left door was destroyed in a car accident in 1971. The door was subsequently changed in 1972 and along with that, the car keys. The new car key, (which I still have in my possession) has on it imprinted something which resembles the image of the Complex unit circle, under the map φ(z)=ez/ez, the inverse of which involves Lambert's W Function. This is the area of the Complex plane inside which the infinite exponential tower +∞z converges. |
