# Updated Math of Beauty interactive

By Murray Bourne, 14 Jan 2014

This one's a bit of fun and not overly scientific.

Why is it that we tend to regard certain people as beautiful regardless of their (or our) race or skin color? Some people feel this is because we are attracted to people whose faces are symmetrical and who follow certain geometric shapes, especially those based on Fibonacci ratios.

This page has always been one of the most popular on IntMath. I updated it so it also works on tablets and (large?) smart phones.

Go to:

Math of Beauty Interactive

Skin deep? On the page, I have a disclaimer that says "inner beauty is more important than external beauty."

## For the geeks

This interactive used to be Flash-based, but of course Flash doesn't work on mobile devices.

So it now uses jQuery (a javascript library) and jQuery-UI (stands for "user interface") instead, with another small file so it works with touch gestures on tablets.

So,is there only Fibonacci number to design beautiful faces or other numbers as well.

HTML: You can use simple tags like <b>, <a href="...">, etc.

To enter math, you can can either:

1. Use simple calculator-like input in the following format (surround your math in backticks, or qq on tablet or phone):
a^2 = sqrt(b^2 + c^2)
(See more on ASCIIMath syntax); or
2. Use simple LaTeX in the following format. Surround your math with $$ and $$.
$$\int g dx = \sqrt{\frac{a}{b}}$$
(This is standard simple LaTeX.)

NOTE: You can't mix both types of math entry in your comment.
