Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham.

<h3>What is edX?</h3>
<p>edX is a not-for-profit enterprise of its founding partners, the Massachusetts Institute of Technology (MIT) and Harvard University that offers online learning to on-campus students and to millions of people around the world. To do so, edX is building an open-source online learning platform and hosts an online web portal at <a href="http://www.edx.org">www.edx.org</a> for online education.</p>
<p>EdX currently offers HarvardX, <em>MITx</em> and BerkeleyX classes online for free. Beginning in fall 2013, edX will offer WellesleyX and GeorgetownX classes online for free. The University of Texas System includes nine universities and six health institutions. The edX institutions aim to extend their collective reach to build a global community of online students. Along with offering online courses, the three universities undertake research on how students learn and how technology can transform learning – both on-campus and online throughout the world.</p>
