## Walter Warwick Sawyer, 1911-2008

This year, a hero of mine passed away. You can find an obituary here:

I encountered W.W. Sawyer when I was a young teenager, through one of his books on mathematics. I have since collected as many books by him as I could find (many are out of print), and I love them all. There is something both about the content and the tone that has stayed with me all through my life and that infuses my own writing about math.

Sawyer’s tone is a beautiful mixture of playfulness and seriousness about his subject. There is nothing stuffy or traditional about his approach; he thinks you and everybody can appreciate math, and he is very much aware of what has killed math appreciation for so many people for so long. And he’s doing real math, not just regaling some impressionable audience with mathematical sleight of hand or legerdemain.

The way Sawyer rearranges the stuff of math, the content, is a work of art. He digs himself and us out from underneath a big pile of rubbish under which the traditional presentation of material has buried the original excitement of a discovery. After a while, you pick up the desire to do some of that digging yourself. Many mathematical discoveries (at all levels) make sense once you appreciate what people were grappling with, what they were trying to figure out, when the discovery was made. The problem context, the historical context, the environment in which both the problem and the discovery made sense – this part is often completely lacking. In traditional presentations of the material, all the scaffolding has been proudly removed from the edifice, and the edifice now looks smooth, forbidding and impenetrable. Mathematicians like Gauss were explicitly proud of their work removing all traces of scaffolding. Sawyer brings the opposite sensibility to mathematics. I specifically remember a short piece Sawyer wrote on the origin of Napier’s logarithms that, in the face of the astounding amount of computation that it called for, at last made it completely obvious why Napier would be interested in high powers of (1 + 1/n), let alone why he was interested in making n big. Take n=10,000, for example.  If you think of a table of powers of 1.0001, calculated in 8 decimal places, till the power reaches 10, you’ve just invented yourself a very long slide rule. (This is worth a later blog post.)

I take my inspiration from W.W. Sawyer, and want to see his work extended to the mathematics of the elementary school curriculum (more precisely, K-8). I dedicate this blog to his work.

Hello,
Since my father, John Sawyer, has done extensive genealogy of our family name, and our roots trace back to 17th century England and Scotland, I am so curious about Prof.Sawyer.

I quite accidentally came upon his name whilst searching for a tolerant (for my son) explanation for my 17 year old son’s excessive perspiration. I know the reason for it, but he’s the type that needs to see it in print.

Strangely, Prof. Sawyer commented on the perspiration of a group of 17 year old boys during a study in 1943. My mother was born in 1942. My query had nothing to do with mathematics, but I saw his name and read his story. I am most intrigued.

Clearly, the – uncategorized- author of this most special obituary was moved by Prof. Sawyer’s brilliance combined with humility and his passion for educating others.

If anyone reads this message, is there any way someone would email me with a further history of this amazing man? Nothing too detailed, just a brief, but more personal update toward who I might look to for further information.

Sincerely,
Michelle S. Mitchell

Extraordinary and brilliant math teacher and writer.

Thank you from W.W.Sawyer’s daughter! I was looking for information regarding my extensive communications with people in India who are setting up a Sawyer Memorial room(!) and came across your site. Much has been happening since his death but I am glad to say I could read their leter to their Guru a couple of years before he died.

oops, I am Sawyer’s daughter..my on screen note just disappeared…did it arrive?
If not, thank you!!!
