It's International Year of Astronomy and all eyes are on Galileo Galilei, whose astronomical observations 400 years ago revolutionised our understanding of the Universe. But few people know that Galileo wasn't the first to build a telescope and turn it on the stars. That honour falls to a little-known mathematician called Thomas Harriot, who excelled in many other ways too. <b>Anna Faherty</b>
takes us on a tour of his work. </div>

<p><i>It's International Year of Astronomy and all eyes are on Galileo Galilei, whose astronomical observations 400 years ago revolutionised our understanding of the Universe. But few people know that Galileo wasn't the first to build a telescope and turn it on the stars. That honour falls to a little-known mathematician called Thomas Harriot, who might have become a household name, had he
bothered to publish his results. This article is a tour of his work.</i></p><p><a href="http://plus.maths.org/content/thomas-harriot-lost-pioneer" target="_blank">read more</a></p>http://plus.maths.org/content/thomas-harriot-lost-pioneer#comments50algebraastronomybinary numberKepler's conjecturerefractionsnell's lawSun, 01 Mar 2009 00:00:00 +0000plusadmin2351 at http://plus.maths.org/content
