From a research path that includes a little bit of rocket science, under sea measurements, radiation detection and measurement, space experimentation and two expeditions to the Antarctic, Mr. McKisson brings a different view of how much physics most people already know from observing the world around them. With a minimal amount of math, attendees will learn a little of the history of physics and may discover that they know more than they thought about what some view as an inscrutable subject.

Comic Book Physics
Even superheroes must obey the laws of physics - or do they? Exactly how much force does it take to leap a tall building in a single bound and what does that tell us about Superman's home planet? Did Spider-Man accidentally cause the death of the falling Gwen Stacy when he caught her with a web? Discover what's right - and wrong - with the physics in the world of comics.

Proton Therapy - Accelerating Protons to Save Lives
Here's a very nice application of particle accelerators (unfortunately, the sound quality is awful!).
In 1946, physicist Robert Wilson first suggested that protons could be used as a form of radiation therapy in the treatment of cancer because of the sharp drop-off that occurs on the distal edge of the radiation dose. Research soon confirmed that high-energy protons were particularly suitable for treating tumors near critical structures, such as the heart and spinal column. The precision with which protons can be delivered means that more radiation can be deposited into the tumor while the surrounding healthy tissue receives substantially less or, in some cases, no radiation. Since these times, particle accelerators have continuously been used in cancer therapy and today new facilities specifically designed for proton therapy are being built in many countries. Proton therapy has been hailed as a revolutionary cancer treatment, with higher cure rates and fewer side effects than traditional X-ray photon radiation therapy. Proton therapy is the modality of choice for treating certain small tumors of the eye, head or neck. Because it exposes less of the tissue surrounding a tumor to the dosage, proton therapy lowers the risk of secondary cancers later in life - especially important for young children. To date, over 80,000 patients worldwide have been treated with protons. Currently, there are nine proton radiation therapy facilities operating in the United States, one at the Hampton University Proton Therapy Institute. An overview of the treatment technology and this new center will be presented.

Hidden Worlds - Hunting for Quarks in Ordinary Matter
Dr. Timothy Paul Smith - Dartmouth College
February 26, 2003
How can scientists know anything about quarks, particles which are 100,000 times smaller than atoms? How do quarks arrange themselves to make ordinary matter? Learn about the hidden world of quarks, the particles which are inside of everything, everywhere!
