Keith Worth Hello, I'm Keith Worth. I grew up for most of my childhood in Yuma, Arizona. Although Yuma has a formidable reputation for any aficionado of the old west genre because of the notorious Yuma Territorial Prison, I found Yuma to be a wonderful place to grow up. Its environs taught me to love the unique and fragile beauty of the desert, mountains, and deep, distant skies of the southwest. It also gave me a great sense of "Yuma"! I left Yuma in 1974 after completing an A.A.S. degree from Arizona Western College. I completed bachelor and master degrees from the College of Engineering at Arizona State University by 1986. Along the way I worked as a professionally certified broadcast communications engineer for major (and not so major) radio and television concerns in the southwest...from San Diego to Phoenix. I joined the faculty at Scottsdale Community College in 1983 to teach in and later coordinate the Electronic/Microprocessor Technology program. I also completed Motorola's "Train the Trainer" program and acted as a technical trainer and consultant for both Motorola and Intel in such diverse areas as SPC and RF plasma systems. By 1994 I had completed over 40 hours of additional college work in mathematics, physics, and computer science after which I became a permanent member of the mathematics department at Scottsdale Community College. I am a past member of the Society of Broadcast Engineers (SBE) and have held professional certification from them as a Broadcast Engineer. I am currently a member of the American Society for Engineering Education (ASEE), MAA, AMATYC, and ARIZMATYC. I have given presentations at several state-level AMATYC-affiliated conferences including ARIZMATYC, NEWMATYC, and MOMATYC. I am also presenting (with Anne Dudley) at the national AMATYC conference in Pittsburgh this fall. As I said before...my interests include anything to do with outdoors in the desert southwest. I also deeply enjoy and appreciate my family. I like reading philosophy, science fiction, historical fiction, and fantasy.
