Goals

C1 The aim of the lecture is to bridge the gap between the basic mechanics course (semester 1 or 2) and the quantum mechanics course and to present the advanced tools of theoretical mechanics developed in the 18th, 19th, and 20th centuries. The course in relativistic mechanics, theoretical astronomy, nonlinear dynamics, chaos theory, and classical electrodynamics can be a natural continuation of the lecture topics.

Extended information/Additional elements

Teaching methods and techniques :

Practice method (doing tasks at the blackboard), Project Based Learning, Lectures, Discussion

Activities Methods of verification Credit conditions
Discussion seminars Activity during classes, Participation in a discussion, Execution of exercises, Scientific paper, Essay, Presentation Credit is awarded to a student who regularly participated in the classes and was active during the classes. In practice, this means that he participated in at least 50% of the classes and showed at least 1 positive activity during the classes. The teacher does not plan a final test or final exam.

Additional info

  • According to the teacher, the classes are to take the form of a seminar ("lecture-exercises"), which means that they will be a combination of a lecture and exercises. In practice, this is to be realized through the active participation of students in the lecture (carrying out calculations, transformations, deductions; of course with the help of the teacher) and solving examples and tasks on the blackboard. The lecture will take the form of a blackboard (written) lecture.
  • Regular exercises for the course are not planned. Tasks to be solved by students on their own will be proposed during the seminar. Additional tasks can be found in the literature and collections of tasks proposed by the teacher.
  • The lecture was based on the textbooks by Landau, Taylor, Greiner, Goldstein, and Rubinowicz, as well as the lecture by prof. P. Bizoń for students of theoretical physics at Jagiellonian University.

Conditions and the manner of completing each form of classes, including the rules of making retakes, as well as the conditions for admission to the exam

Credit is awarded to a student who regularly participated in the classes and was active during the classes. In practice, this means that he participated in at least 50% of the classes and showed at least 1 positive activity during the classes. The teacher does not plan a final test or final exam.

Method of determining the final grade

Final grade:

  • A grade of 3.0-3.5 (dst or dst +) is obtained by a student who has participated in at least 50% of the classes and has demonstrated positive activity at least once during the classes. It is also a condition for passing the course for all students (with a grade of 3.0). A student with more than one activity will receive a grade of 3.5.
  • A grade of 4.0-4.5 (db or db +) is obtained by a student who, above all, will present independently made and correct solutions to tasks and examples left at the lecture for self-solution (4.5 - all, 4.0 - what at least half).
  • A 5.0 (very good) grade is awarded to a student who, above all, develops an issue of his choice regarding theoretical mechanics (e.g. selected from the list of issues proposed by the teacher or by himself) and presents it in the form of a presentation (a lecture, a multimedia presentation, or mini-blackboard lecture, etc.), or an essay (if time is limited).

Manner and mode of making up for the backlog caused by a student justified absence from classes

A 50% attendance is required from the student during the classes. The student's absence of <50% does not require additional compensation, apart from supplementing notes and solving tasks left for independent solutions (in the case when the student aspires to receive a grade higher than 3.5). Absence of more than 50% of the classes will result in failure to complete the course.

Prerequisites and additional requirements

Basic course in mechanics and mathematical analysis (within the first year of first-cycle studies).

Rules of participation in given classes, indicating whether student presence at the lecture is obligatory

Seminar: Attendance is obligatory. A 50% attendance is required from the student during the classes.
