Fortunately, there are now cross-browser friendly javascript-based mathematics tools for displaying mathematical expressions well on a website. There are two parts: the javascript and CSS external files, and the code to use for your amthematics.

JQUERY library files

On this website, we use various techniques. A comprehensive one is jqmath, a version of jquery library. To use, place these links to the corresponding .css and .js files (or download them to your site) on the page you wish to use the jqmath on:

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=UnifrakturMaguntia">

<link rel="stylesheet" href="http://www.sciencelibrary.info/js/jqmath-0.4.0.css">

<script src="http://www.sciencelibrary.info/js/jquery-1.4.3.min.js"></script>

<script src="http://www.sciencelibrary.info/js/jqmath-etc-0.4.0.min.js"></script>

E.g. the quadratic equation:

$$x={-b±√{b^2-4ac}}/{2a}$$
The jqmath Code

This table is a list of jqmath code examples and the resultant display. To use, place the code within \$\$ characters. Single dollar sign characters before and after displays the maths in line, and double dollar signs create a block element of the maths.

e.g. single \$: $∑↙{i=0}↖n i={n(n+1)}/2$

e.g. double \$: $$∑↙{i=0}↖n i={n(n+1)}/2$$

Great Scientists

Francis Crick

1916 - 2004

Francis Crick was a physicist who worked with molecular biologist James Watson to discover the structure of the DNA molecule in 1953. Their work heralded the 'coming of age' of the biological sciences, and permitted the later breaking of the 'code of life'.
