It has been studied by a host of intellectual greats. His systematic approach to Geometry is not&nbsp;a&nbsp;only a tremendous study in how to think and reason, but it became the paradigm that later philosophers would attempt to follow in setting up their own systems of thought. There is really no other mathematical text that rivals its impact on intellectual history.&nbsp;&nbsp;This tutorial is highly recommended not only for its tremendous historical value, but also as a fine addition to the Geometry-starved Saxon program. The only fault I see with the Saxon programs is its meager treatment of Geometric proofs. Along with Saxon, most modern math texts are downplaying Geometric proofs because they are teaching to the SAT and it does not require proofs. But after going through the magnificent proofs of&nbsp;Euclid&nbsp;, you will see why his work is truly a mathematical classic.&nbsp;&nbsp;In order to enroll in the second year of the Great Books Tutorial, all students must take my Euclidean Geometry course.&nbsp; The course requires 5-10 hours a week of preparation and should be seen as a college level mathematics course.&nbsp; The Elements comprise the greater part of the freshman year mathematics program at St. John&#8217;s College and my tutorial is closely modeled after that course.&nbsp;How does this course compare to a conventional Euclidean Geometry course?&nbsp; Conventional high school Geometry texts study proofs for the first semester of the year and then study the application of Algebra to Geometry that was developed by Descartes (Cartesian) during the second semester.&nbsp; Though based on Euclid, the conventional study of proofs is usually much less thorough than the proofs in Euclid.&nbsp; Cartesian Geometry is on the SAT and should be studied as a separate subject if your child will be taking that quiz.&nbsp; Saxon eliminates a separate year for Geometry entirely and just studies Cartesian Geometry in conjunction with Algebra and Advanced Math.The text for the tutorial is&nbsp;Euclid&#8217;s&nbsp;<em>Elements<\/em>, from Green Lion Press.

Its beauty lies in its logical development of geometry and other branches of mathematics. It has influenced all branches of science but none so much as mathematics and the exact sciences. The&nbsp;<em>Elements<\/em>&nbsp;have been studied 24 centuries in many languages starting, of course, in the original Greek, then in Arabic, Latin, and many modern languages.<\/p>\n\n\n\n<p>I&#8217;m creating this version of Euclid\u2019s&nbsp;<em>Elements<\/em>&nbsp;for a couple of reasons. The main one is to rekindle an interest in the&nbsp;<em>Elements,<\/em>&nbsp;and the web is a great way to do that. Another reason is to show how Java applets can be used to illustrate geometry. That also helps to bring the&nbsp;<em>Elements<\/em>&nbsp;alive.<\/p>\n\n\n\n<p>The text of all 13 Books is complete, and all of the figures are illustrated using the Geometry Applet, even those in the last three books on solid geometry that are three-dimensional. I still have a lot to write in the guide sections and that will keep me busy for quite a while.<\/p>\n\n\n\n<p>This edition of Euclid\u2019s&nbsp;<em>Elements<\/em>&nbsp;uses a Java applet called the Geometry Applet to illustrate the diagrams. If you enable Java on your browser, then you\u2019ll be able to dynamically change the diagrams.
