During the time I was working in nuclear physics research, I became aware that our country had something like 20,000 nuclear warheads that could be delivered at intended targets in less than 40 minutes and that the Russians had the similar capability. I began to see that humanity was facing a crisis. Although I understood that one person could not make much of a difference in reducing this threat to humanity, I switched into teaching in 1975 as my way of making a small contribution.
My career at the University of South Carolina Aiken has been devoted to finding better and more satisfying ways for students to learn physics. Please see my articles describe my thoughts on inproving teaching and learning. Sroll down about 10 where you see the links numbered 1). 2), 3), etc at

Hold you mouse over any of the small photos (at left) for a statement of album contents and number of photos. You may then click any photo to view a full introduction to the contents of each album. Then, clicking on the Album Title (or Album Photo) will take you to a page of 18 "thumbnails" having a description for each photo. You may click on any of these to see a larger photo.
