- An = number of units of alcohol consumed
- S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
- L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
- Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
- d = distance from 'person of interest' (metres; 0.5 to 3 metres)
This is not a joke. It comes from a BBC Article based on a Manchester (England) University study:
"Researchers at Manchester University say while beauty is in the eye of the beer-holder, the amount of alcohol consumed is not the only factor.
Additional factors include the level of light in the pub or club, the drinker's own eyesight and the room's smokiness.
The distance between two people is also a factor."
Now if they could just get that formula for what "aesthetically pleasing" is equal to, we could settle this beauty thing once and for all.
