These are pdf representations of selected lectures and specialty courses.

Diver's Guide to Hyperbaric Chambers: This is the lecture portion (80 slides; 12.1 MB) of my course in an introduction to hyperbaric chambers. This course included a field trip to Bronson Hospital (Kalamazoo, Michigan) for a chamber dive to 165 fsw.

Dry Suit Diving: This is the lecture portion  (206 slides; 18.5 MB) of my umich academic course in dry suit diving. The "Not Being Cold" portion is an extended version of slides furnished to me by Dick Long at DUI.

Friday Night Review: In the academic world, the lecture portion of the class is often finished a full semester before the open water. This is the review session used on the Friday night  (105 slides; 4.6 MB) before the open water for my umich students. It is my first made power point slide set.

Oxygen Enriched Air (EANx): This is the lecture portion (248 slides; 26.6 MB) of my umich academic course for oxygen enriched air (Nitrox).

Oxygen Provider: This is an augmented (based on DAN slides furnished to instructors in the 1980's, 131 slides; 14.2 MB) course with an extended lecture on diving maladies / physiology suitable for the umich academic diving community.

PFO and Clearing Ears: This is lecture comments (13 slides; 1 MB) on the Patent Foramen Ovale (PFO) and equalizing pressure ("clearing") of the middle ear;

Includes comments on Valsalva dangers and the "wonderfulness" of the Frenzel method of equalizing middle ear pressure with the environment.

River Diving: This is the lecture portion (126 slides; 11 MB) of a river diving course based on the St. Clair River (one of the swiftest commercial waterways in North America) in Michigan.

Why I Don't Train Kids: This is the talk I gave at Our World Underwater (69 slides; 3.2 MB) on my rationale for not training anyone under the age of 18.

No Cell Phones in Class:  This slide set  (132 slides; 18.7 MB) was developed to justify my denial of cell phones in the chemistry classes I taught. After a student told me that my cell phone radiation/ security concerns were "conspiracy theory, " I added a few slides on privacy and security associated with wireless communication. Students were surprised to see that no wireless device sold in the US has passed a consumer safety protocol.

In class, I passed around a microwave energy detector and students were surprised to see their cell phones and laptops were producing energies exceeding the recommended long term exposure limits for microwave radiation.

Banning cell phones in the classroom raised my % (A+B)'s  from  71 % to 91 %.
