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.

Greetings to all.
I'm looking for the best textbook for introductory physics that has clear explanations and is problem-oriented. I'd also appreciate any recommendations for textbooks for the AP Physics 1 exam.
TL;DR Summary: I'm looking for a book on statistical/data analysis.
Hey all. I've been doing statistical analysis in my research (such as using PCA and LDA), but I have never received a formal education on statistical analysis or data mining, and what I know about analysis is quite scattered...
Hello,
I am currently preparing to learn the 8.01 course "Physics I" via the MIT OCW and I am trying to find an adequate textbook for that purpose. In the three courses that I have found, the first two use:
Young, H. D., and R. A. Freedman. University Physics.
which is quite expensive in my...
Hi!
I want to self study some of quantum mechanics so i need introductory textbook. I've taken courses on linear algebra that covers all "Linear algebra done right" by Sheldon Axler, multivariable calculus, two courses on general physics and the basics of differentials equations.
I really like...
The way I was doing is that I list events
1. lightning hits x=0 this is (x_1=0,t_1)
2. lightning hits x=12 (x_2=12,t_2)
3. left lightning reaches "me" (x_3=9,t_3)
4. right lightning reaches "me" (x_4=9,t_4=t_3) t_4=t_3 since "I" see the lightning at the same time
Then the...
Are there any good introductory texts aimed at students with only a working knowledge of High School Algebra? I currently have:
Probability: An Introduction by Samuel Goldberg
I do plan on eventually learning Calculus, but I would like to start learning probability sooner.
I understand the reaction from the majority of those here in PF to John's reference to his faith in this book: however, if you set aside all such references for the moment and just look at the way Physics is presented in the book how would you who have read it rate it on a scale of 1 to 10 for...
Hello everyone!

Are there any books that are NOT like "University Physics (Young)" / "Fundamentals of Physics (Halliday)" in presentation, but that are suitable for a first course on the subjects of those books? The mentioned books are too "flashy", full of colorful boxes, etc. I don't like this and I find it...
What exactly is the difference in the way an general physics book (Halliday and Resnick, Young and Freedman) covers topics like mechanics, EM, and thermodynamics, compared to respective books like Kleppner and Kolenkow, Griffiths, and Schroeder, other than the amount of material covered for each...
The left pic is the initial state and the right pics are 2 different descriptions for a metal under electric field E. Are the 2 on the right contradictory and which is correct?
Hi,
I have undergraduate level knowledge about mathematics, quantum physics, and general theory of relativity. Now I am curious about chaos theory, and I would be grateful for suggestions of good introductory books to chaos theory. They may be both introductory and a bit more advanced.Sten Edebäck
Hi,
I have been studying physics again and I was looking for a good introductory book for thermodynamics. I wanted to know if there is a book in thermodynamics that would be the equivalent to "An introduction to Mechanics" by Kleppner/Kolenkow, or "Electricity and Magnetism" by Purcell? These 2...

Hello! I'll be taking a probability and statistics course this semester. Does anyone know of any good textbook? I have access to an extensive catalogue of books on springer, so it would be extremely preferable for me if you could recommend something from there.
Thanks.
Hello! Can someone point me towards some introductory levels readings on Rabi and Ramsey spectroscopy. It seems that most readings online are scientific papers, I would like something more basic (e.g. lecture notes). Thank you!

I need some rigorous introductory books on Electromagnetism, by rigorous I mean detailed and mathematical.
Many books that I have found don’t actually work out the field produced by current carrying toroid, solenoid or even some other simple electrostatic situations. They just write “by...
I am looking for a book/notes on the topics mentioned in the title that would be accessible to an undergrad. I have a background in grad quantum and statistical mechanics, but most resources I found on those topics assume a familiarity with QFT, string theory, gauge theory, and general...
By Fluid Mechanics I mean the mechanics of fluids, both at rest and in motion. I'm unable to find introductory books on Fluid Mechanics which contains everything in itself, for example I downloaded Fundamentals of Fluid Mechanics by Munson, Young, Okiishi, Huebsch and I don't know why but I...

I am going through "Circuit Analysis for Dummies". On pg 18, it says, "If you calculate the power dissipated as 0.1 watts, then a 0.25-watt resistor can handle this amount of power. A 0.125-watt resistor should be able to handle that amount as well, but when it comes to power ratings, err on the...
$$r<x<s$$
$$s-r>0$$
We enploy the Archimedean principle where
$$n(s-r)>1$$
We employ density of rationals where
$$\exists [m,m+1] \in Q$$
Such that
$$nr\in [m,m+1)$$
Therefore
$$m\leq nr \lt m+1$$$$ \frac m n \leq r \lt \frac m n + \frac 1 n $$
Since
$$ \frac m n \leq r $$
Then
