Rated 5 out of 5 by from Great Professor, Great Lectures I wasn't sure how much I was going to get into this -- my high school and college math are decades in the past, didn't know if this was going to be over my head or not. But I was instantly drawn in by the professor and not only his expertise in math, but with the way he could tell a story. I learned more about the past and the history and the people than I ever knew before, and I found myself replaying lectures because they were so interesting. Some of the exercises were over my head (although much of it came back as I worked through them). But I was intrigued and pulled into it enough that I actually bought or checked out from the library several of the resource books listed. He woke up an interest that has continued well past the lectures. Professor Dunham was so engaging, so entertaining and so enthusiastic about the people and the theorems that I recall thinking that if my own professors had been half as interesting as him, I would have had a much easier time in college. I'm sure I will be returning to this course again!

Rated 5 out of 5 by from Outstanding Course Truly an exceptional educational experience. Prof. Dunham brings an engaging, enthusiastic manner that is infectious. His inclusion of the “Mount Rushmore” of mathematicians is on the mark, as is his selection of their works to address. Many of the proofs he address are quite complex but he goes through them systematically, assisted by outstanding graphics from the production team. Only criticism I can offer is that I was left wanting more! Perhaps 20th century mathematicians, say Kurt Godel and the Incompleteness theorems, etc. (Note: reviewer is a Ph.D. Experimental Astrophysicist who hasn’t been in a classroom in many years.)

Rated 5 out of 5 by from Fabulous! This course was superb! Professor Dunham covers the landscape of mathematical thought from antiquity through the late 19th century with humor and interesting stories about the great mathematicians while at the same time weaving in some terrific mathematics. it provides a remarkable appreciation for the genius of generations of famous mathematicians, many of whom one has heard, and some of whom are more obscure. I can't wait to watch the entire course again.

Rated 5 out of 5 by from Excellent course, excellent lecturer. I found this to be an excellent course. Professor Dunham is a warm and likeable lecturer, with a pleasant voice and always good-humoured. His preparation and delivery was excellent - obviously achieved with much practice. He spoke clearly and takes pains to make sure everything is clearly understandable. (Towards the end of the course I actually switched to 1.5x speed, as he was clear even at this speed). It didn't feel like I was being lectured to - it felt like I was being entertained! I especially like his particular way of adding little fillers to keep contact with his audience - "almost there", "let's recall what we are trying to prove", etc. Most importantly, the content was very good. It is an entertaining history of mathematics, from 1850 BC to the end of the 19th Century, from the Ancient Greeks to Cantor, with lots of good stories to illustrate the lives and circumstances of the great mathematicians that Professor Dunham has selected (and a good choice it is too!). He included just the right amount of mathematics for me - enough for me to work along and understand the theorems better, but making this a pleasure rather than an effort. I do have a Maths degree, but still learned a lot, especially about how mathematics developed through the centuries. For example, I didn't realise that the use of x's and y's in algebra was quite a late invention - until the time of Newton, problems and solutions were communicated using long-winded prose! The presentation is a monologue - but with on-screen animated graphics which are all very clear and helpful. Overally, I would recommend this course to anyone (adult or teenager onwards) with any slight interest in mathematics, at any level of mathematical education.

About

William Dunham

Mathematics is perhaps the most useful of subjects, but my interests are not utilitarian.  Rather, I look to the great landmarks from the history of mathematics and present them as creative achievements that are a joy to behold.

INSTITUTION

Muhlenberg College

Dr. William Dunham is the Truman Koehler Professor of Mathematics at Muhlenberg College in Allentown, Pennsylvania. He earned his undergraduate degree from the University of Pittsburgh and his M.S. and Ph.D. in Mathematics from The Ohio State University.  Before his current appointment at Muhlenberg, Dr. Dunham taught at Hanover College in Indiana, receiving teaching awards from both institutions as well as the Award for Distinguished College or University Teaching from the Eastern Pennsylvania and Delaware Section of the Mathematical Association of America. He was a Visiting Professor at Ohio State and at Harvard University, where he was invited to teach an undergraduate course on the work of Leonhard Euler and to deliver the Clay Public Lecture in 2008.  Dr. Dunham's great theorems approach to teaching mathematics was fostered by a 1983 summer grant from the Lilly Endowment, which also led to his first book, Journey Through Genius: The Great Theorems of Mathematics—a Book-of-the-Month Club selection that has been translated into five languages. Other books followed in addition to articles on mathematics and its history, earning him numerous awards from the Mathematical Association of America and other organizations. He has presented popular talks on mathematics throughout the United States and has appeared on the BBC and NPR's Talk of the Nation: Science Friday.
