What is Introductory: Definition and 366 Discussions

Introductory diving, also known as introductory scuba experience, trial diving and resort diving are dives where people without diver training or certification can experience scuba diving under the guidance of a recreational diving instructor. Introductory diving is an opportunity for interested people to find out by practical experience at a relatively low cost if they would be interested in greater involvement in scuba diving. For scuba instructors and diving schools is it an opportunity to acquire new customers. An introductory diving experience is much less time-consuming and costly than the completion of autonomous diver training, but has little lasting value, as it is an experience program only, for which no certification is issued. Introductory scuba diving experiences are intended to introduce people to recreational diving, and increase the potential client base of dive shops to include people who do not have the time or inclination to complete an entry level certification program.

    Introductory books on quantum mechanics

    The math part seems really interesting too, it is mainly based on linear operators on hilbert spaces. But, it seems to me that it only uses inner product (pre-hilbert) spaces, then why these authors (and also paper authors) refers always to hilbert spaces?
