I learnt about this a couple of times actually. It has to do with "The Golden Ratio" discovered by Leonardo da Vinci. (I'm pretty sure the Egyptians came up with it first though).

This mask of the human face is based on the Golden Ratio. The proportions of the length of the nose, the position of the eyes and the length of the chin, all conform to some aspect of the Golden Ratio.
The Golden Ratio (or "Golden Section") is based on Fibonacci Numbers, where every number in the sequence (after the second) is the sum of the previous 2 numbers:
1, 1, 2, 3, 5, 8, 13, 21, ...
We will see (below) how the Fibonnaci Numbers lead to the Golden Ratio:
Φ = 1.618 033 ...
Let's look at the ratio of each number in the Fibonacci sequence to the one before it:
1/1 = 1
2/1 = 2
3/2 = 1.5
5/3 = 1.666...
8/5 = 1.6
13/8 = 1.625
21/13 = 1.61538...
34/21 = 1.61905...
55/34 = 1.61764...
89/55 = 1.61861...
If we keep going, we produce an interesting number which mathematicians call "phi" (Golden Ratio or Golden Section):
Φ = 1.618 033 988 7...
This ratio was used by architects and artists throughout history to produce objects of great beauty (like Michelangelo's "David" and the Greek temples.)
blah blah blah...

Personally I think it's bs and kills the appeal of attraction. They used Jessica Simpson as an example.
