8mm Film Loops

I have been working my way through the loops trying to make an assessment of which are useful. I have added a rating to those which have been reviewed and comments where appropriate. The rating consists of three parts: one to five stars; a subject code; and a level, for example: [*****;QM;3]. Ratings reflect my opinion of the value of a loop for teaching in a lecture setting at SFU and are, of course, subjective.
First part

* : awful

** : some redeeming value

*** : average, may be of interest

**** : definitely worth a look from the prof, contains useful ideas or techniques for presentation

*****: a must use

The loops were purchased in sets with titles such as "Triumph of Mechanics" or "Lecture Demonstrations in Physics". Some of these sets contain material of widely varying subject matter. The loops are filed under set title and are listed in this way below. Some loops are listed under more than one subject heading.

Some of the loops are available on the videodisc The Miller Collection and bits of some have been reworked on the Physics Cinema Classics set of videodiscs. Some are also available as short 16mm films. Some of these are indicated in the list. .

• Mechanics
• Waves and Oscillations
