Wednesday July 25, 2007 6:50 am Lethbridge

It is +15 C with a high forecast of +26 C. Sunrise 5:52 Sunset 21:24 Hours of daylight: 15:32

A. Morning Musings

7:20 am

Today will be a short break in the hot weather, but then it is supposed to warm up again. I will take the truck in to have a mirror replaced and will take a math book with me and see how the morning unfolds.

Immediate Description Time
Literature Begin reading "Deactivated West 100" by Don McKay 1 hr
Mathematics Make notes for ch. 1 of "Modern Abstract Algebra" by Ayres 1 hr
Mathematics Complete problems 2.13 - 2.? of "The Humongous Book of Calculus Problems" 1 hr

C. Actual Learning Activities

10:25 am

Another brief insight into my mind. I have been reading Don McKay's prose/poetry in "Deactivated West 100" for much of the last hour. He is a geologist with a poetic mind (or a poet with a geologic background) (or ...). I tried reading this book when I first bought it about a month and a half ago but for some reason it didn't take. This morning it did.

I now have a freshly cut Gala apple, a few slices of two-year old Balderson cheddar cheese (white, not orange), and a fresh cup of coffee beside me, and an Apple MacBook Pro in front of me. I want to capture a few special quotes from both McKay and from the Murakami novel I finished yesterday.

I looked at a few examples of proofs in the Schaum's Outline series on Modern Abstract Algebra while waiting for the truck mirror to be replaced.

Modern Abstract Algebra. (1965) Frank Ayres

Chapter 1 Sets

Here are my scans (original at color - magazine, 200 dpi, export at width of 600 pixels) of the problems I completed in a one hour session this morning.

This was another good start. It is now obvious that I need to study and memorize many of these basic relationships involving sets. But the memorization should follow understanding, which is based on a careful attention to the meaning underlying the notational conventions.
