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

Robert Hooke

1635 - 1703

Robert Hooke was an English polymath and all-round genius, active in an extraordinary range of fields during the English Enlightenment. History has not been fair to Hooke, obscuring his contributions in the shadow of his gigantuan rival, Isaac Newton.

Quote of the day...

Physics is mathematical not because we know so much about the physical world, but because we know so little; it is only its mathematical properties that we can discover.
