   3. Note the catalog topics must be covered in the course by UNLV policy.
4. Library: See UNLV Library and also UNLV Library Search. There are NO library resources and NO specific external information resources recommended for this course---except the course course textbook: see below.
5. Artificial Intelligence (AI): AI can be used as an alternative source of information, but remember it CANNOT be a super-reliable source of information. But there is to be NO use for solving particular problems or quizzes/exams. What you need to do for preparing for exams and all of scientific/engineering life is to develop the skills to do a problem on your own OR by engaging, roughly speaking, in the Socratic method with someone else including the instructor and/or study friends.
   Using AI to solve problems is like taking a forklift to the weight room.
6. Course Website / Extended Syllabus: None so far for this course.
7. Course Textbook:
   1. OpenStax: University Physics: Volume 1: pdf.
   2. OpenStax: University Physics: Volume 2: pdf.
   3. OpenStax: University Physics: Volume 3: pdf.
   4. The textbook is free online and can be found by googling "OpenStax University Physics Volumes 1, 2, 3".
      
   5. Homeworks: There is a homework for almost every chapter of the Textbook we cover, but only some homeworks will be handed in and even for those only some of or NONE of the problems will be marked. A full-answer question needs few or no words---unless a word answer is asked for---and does NOT need to be lengthy, but it does have to be detailed enough that it is convincing to yourself, the instructor, the grader, and your fellow students. The multiple-choice questions will NOT be marked, but some will occur on exams, and so you should always answer them as if you were writing exam and had to pull the answer out of memory or by deduction.
      Self-testing on homeworks and problems from other sources is the key preparation for exams and all the rest of your life.

   Daily Routine: M--F, 8:00--9:40 am for class in BPB 106 and the rest of the day for study.

   1. Lecture: ∼ 50 minutes.
   2. Group Activity ∼ 5 minutes: People form groups and answer onscreen multiple-choice questions: Unmarked, but you better do it seriously.
   3. Break: ⪅ 10 minutes: Group activity plus break ≤ 15 minutes always.
   4. Lecture: ∼ 35 minutes.
   5. Office hours: 10:30--12:00 am in faculty office BPB 244, 2nd floor, far west small corridor, moving to BPB 250 if there is a crowd.
   6. Office hours: 1:00--4:00 pm in faculty office BPB 244, 2nd floor, far west small corridor, moving to BPB 250 if there is a crowd.
   7. Meetings can be by Zoom.
   8. Academic Success Center: Tutoring: They do include PHYS 195/196 - Physics for Scientists and Engineers A/B, but NOT for the current summer semester. See the 2026 Summer Schedule for the Tutoring Lab.

8. Required Readings: The course notes and relevant parts of the chapters of the textbook being lectured on.
9. Homework Due Dates: To-be-handed-in homeworks are due at the BEGINNING of the class the day after the corresponding chapter of the textbook has been completed in class. For this summer semester, homeworks receive a full mark for apparent completeness. Probably toward the end of the summer semester, there will be NO MORE to-be-handed-in homeworks. Late homeworks are allowed only in the case of extenuating circumstances.
   The homeworks are the study guide.
10. Evaluation:
    1. Homeworks: Tentatively, 10 %.
    2. Semester Exams: Tentatively, 4 semester exams (50 minutes) on Fridays each worth 15 % each for a total of 60 %.
       After the exams, we have a 10 minute break and then a 40 minute lecture.
    3. Final: Tentatively, 100 minutes on the last Friday, 30 %.
    Final grades are always set by instructor drawing grade lines by personal judgment in order to get a fair distribution on the 12-point scale: A,A-,B+,B,B-,C+,C,C-,D+,D,D-,F. However, before final grades, the instructor just uses satisfactory S for above 60 % and D+,D,D-,F for below.

12. Student Learning Outcomes:
    1. Learn the topics included in the catalog description.
    2. Be able to apply those concepts in those topics to problems, and thereby solidify the concepts.
    3. There are more concepts to learn than can be tested. But you should learn as much as you can: that learning is what you need to know for the rest of your professional careers. Ideally, the course should recreate the subject in your own mind.
    4. As in all intro physics courses, we generally study idealized systems which often work to good accuracy in applications, but NOT always to good accuracy. In dealing with real systems to high accuracy, you often must include complicating secondary effects that are usually beyond the scope of this course.
    5. Learning requires multiple modes:
       1. Learning is by following the lecture in your mind and questioning/challenging it in your mind as much as you can. Asking the instructor questions too. It's hard over 50 minutes, let alone 100 minutes.
       2. Learning is by understanding notes (your own or the instructor's), NOT just relying on the textbook (which is the opposite of compact: it's verbose). The instructor's notes are their personalized mnemonics. If you want to rely on them, you should still make your own notes even if they are just written right on top of the instructor's notes. The instructor actually recommends this---even though it takes a lot of paper.
       3. Learning by thinking and talking a subject. There's really no other way. Our neural networks, NOT AI's, need the workout.
       4. Learning is by spending ∼ 3 times more time on the course out of the lecture period than in it if at all possible. Going over the textbook, notes, concepts, homework problems, homework solutions.
    6. Have some fun with some of the most profound concepts of the universe.
