A & T Lectures has decided to go green. We feel that you having an electronic version of the presentation is a better choice. The Power Points will be available one week before and after the lecture date. Please download and print the lecture if you feel you need it at the live lecture.We will be handing out work books at the lecture for you to take notes. Thank you for understanding that many of our printed Power Points end up in the garbage.Why not go green and save a few trees! Just "click" on the lecture you want to print or save.
