These are pdf representations of selected lectures and specialty courses.

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

BuoyancyThis 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 (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.

Dive Physiology:  This is a collection of slides covering various dive physiology topics from a variety of classes (127 slides, 6.7 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  (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: 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 early 1980'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)

Oxygen Enriched Air (EANx): This is the lecture portion (248 slides; 17.7 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; 9.5 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 (15 slides; 1.2 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  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 ClassThis slide set  (134 slides; 18.9 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 (allegedly turned off)  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 %.
