While browsing the Internet I found an interesting website on abstract mathematics by Professor Charles Wells. The site is organized into subsections like chapters in a book. I’m especially interested in the use of different fonts, sizes, and colors to illustrate important points. Perhaps the important points are emphasized because of the experience of the author as a teacher. The presentation is such that most people can understand it if they have some background in the field. It is fun to review the site and remind oneself of the notation and key base concepts in abstract mathematics. It is very refreshing relative to the traditional mathematics education for engineers and scientists (that I was a part of for the most part). I wish more professional scientists, engineers, and mathematicians (read researchers) maintained personal websites or offered basic notes online. It is a service to society.
