PDF FILES

These are pdf representations of selected lectures and specialty courses.

Slides are not learning stand-alones. These are simply notes used to augment lectures.

Buoyancy:  This is a lecture portion (39 slides; 2 MB) on buoyancy and buoyancy calculations based on my article Archimedes, A Gold Thief, and Buoyancy. Also includes "extra stuff" on significant density related items.

Diver's Guide to Hyperbaric Chambers: This is the lecture portion (87 slides; 13.0 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.

Dive Physiology:  This is a compilation of slides covering various dive physiology topics from a variety of classes (132 slides, 10.8 MB). Topics include hyper and hypothermia, PFO's, Ear Issues, Near Drowning, CO₂ Issues, Shallow water Blackout, CO, Nitrogen Narcosis, DCS, Air Embolism, and Oxygen Toxicity.

Dry Suit Diving: This is the lecture portion  (229 slides; 21.7 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: This is the review session used on the Friday night  (105 slides; 4.6 MB) before the open water weekend for my basic scuba students. It is my first made power point slide set. This demonstrates the level of knowledge that was present in the recreational community (the way I was trained) before the concerted effort (beginning in the late 1970's) to remove lecture topics and in-water training time from basic training.

Gases:  This is an expanded version of my web article A Gas Law Primer, (86 slides, 3.4 MB).

Great Lakes Shipwreck Preserves: This is an overview of the Great Lakes Shipwreck Preserves (29 slides, 5.0 MB).

I Am Certified, Why Not Authorized? This slide set (29 slides, 2.83 MB) is used an an introduction to the U of Michigan Diving Authorization process for those wishing to dive on university research projects. The title comes from a frequent question from recreational divers wishing to dive on research projects at the University of Michigan.

Oxygen Enriched Air (EANx): This is the lecture portion (250 slides; 26.6 MB) of my umich academic course for oxygen enriched air (Nitrox).

Oxygen Provider: This is lecture portion of the DAN oxygen provider course (137 slides; 14.6 MB) course with an extended lecture on diving maladies / physiology utilized for the umich academic diving community.

PFO and Clearing Ears: This is lecture comments (17 slides; 1.22 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 (127 slides; 17.4 MB) of a river diving course based on the St. Clair River (one of the swiftest commercial waterways in North America) in Michigan.

Using the SeaDoo Bombardier DPV This slide set (46 slides; 2.91 MB) explores practical aspects of diving with the SeaDoo Bombardier DPV. This DPV design is one of the most popular recreational class DPV's.

What Is Science Diving?: This is a slide set (42 slides, 7.41 MB) of a guest lecture for a nautical archeology class at the University of Michigan.

Why I Don't Train Kids: This is the talk I gave at  the 2001 Our World Underwater dive show (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  (168 slides; 30.5 MB) was developed to justify my denial of cell phones in the introductory chemistry classes I taught at a local community college. It is still being updated.

The first day of class, I passed around a microwave energy detector. No student ever indicated an observed energy level for their mobile device or laptop below the recommended long-term exposure threshold.

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