As a medical researcher at Yale, Hartman has contributed to the international literature on malignant disease, in particular, cancer of the breast, prostate, bowel, and brain. He is an expert in the use of radioactive materials to treat cancer.

As a surgeon at Mayo, Hartman performed open heart surgery and, later, had open heart surgery performed on him. You might say the topic is dear to his …uh…heart.


An undergraduate with degrees in Chemistry and Mathematics and a minor in Biology, Hartman added, through persistent interest, knowledge of Geology, Astronomy, and Paleoanthropology. As a physician it was necessary he become proficient in Nuclear Physics. No scientific topics are out of bounds.

Rocket Science

How often have you heard the expression "...but look, this isn't rocket science!"

Hartman as a young chemist (still in high school) experimented with numerous rocket fuels (solid propellants) to discover which was the most useful one. (On this he has an opinion.) Then he launched numerous rockets into the heavens, some with biological experiments contained in the nose cone. And a lot more. Somehow, he escaped being arrested for all of this. This talk is on Rocket Science, and you don't get many of those!

Culture and our Social Condition

How do we communicate? Language! What are its origins, and how does language change with time? (This is one of Hartman's special interests.)

What is the nature of our education? What should our politics be, in a perfect world? Which is more important, equal opportunity, or equal outcome? How does Morality fluctuate among various cultures?

Oceans of the World, and Sail Boats

Hartman grew up in Atlantic City, was on the island's beach patrol for nine years, and knows all about ocean conditions and hazards, and is familiar with the Atlantic and Pacific Oceans, the Mediterranean, Caribbean, and Aegean Seas, and the Gulf of Mexico. He has been sailing all his life, and was once a decent surfer.


The emphasis here is on the oldest history, even from before history is recorded. Greeks, Egyptians, Phoenicians, Persians, and the early Europeans, among others, have interesting stories to tell.

A Few Suggestions for Individual Lectures:

Some topics can be used in nearly every setting. For instance, the title "The Lost City of Atlantis" will have appeal for a variety of listener groups. We begin with the origin of the legend from Plato at about 370 BC calling upon information according to Greek ruler Solon of 200 years earlier, in which Plato said it was "beyond the Pillars of Hercules". We then examine the places in the world which have claim to the Atlantis location, or claim to being the "Pillars of Hercules". Other topics with wide appeal are:
