NON-LINEAR PHYSICS - 2021/2
Module code: PHYM038
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
Non-linear physics introduces the relevant theory with examples in physics, astrophysics, chemistry, biology and engineering. The material is developed through lectures and examples classes, and applied in the coursework.

|Assessment type||Unit of assessment||Weighting|
|Examination||END OF SEMESTER EXAMINATION - 2 HOURS||70|
The assessment strategy is designed to provide students with the opportunity to demonstrate their insight into non-linear physics and complex phenomena. The coursework assigned during the semester allows the student to put into practice the concepts learned in class, therefore building a deeper understanding of non-linear phenomena and mastering the techniques used in their analysis. The final written examination, at the end of the semester, assesses the overall understanding of the fundamental concepts and theory of complex phenomena.
Thus, the summative assessment for this module consists of:
One piece of coursework (30%) to be completed during the semester requiring approximately five weeks. The coursework must be completed by the end of the semester.
One two-hour examination at the end of the semester (70%), with a section A of compulsory questions and a section B of two questions chosen from three. In Part A answer all questions (20 points). In Part B answer two questions out of three (20 points each). If all three questions in Part B are attempted only the best two will be counted.
Formative assessment and feedback
Students receive continuous feedback through discussions during class time. Assessment of the submitted coursework is returned to the students with feedback on their performance.
- To provide a sound grounding and the basic theorems, methods and applications of the theory of non-linear physics. To gain computational and mathematical skill to characterise the qualitative complex systems in physics, finance, and other disciplines.
- To then encourage the in-depth investigation of aspects of non-linearity through extended coursework problems.
|001||Upon successful completion of the module the student will be able to appreciate the implications of non-linearity in physics and identify its basic mechanisms. They will be able to analyse and classify the motion of complex non-linear systems by identifying their qualitative features and by categorizing them in terms of periodic, quasi-periodic or chaotic behaviour. They will be able to recognize effects of non-linearity in situations of everyday life.|
|002||On successful completion of the coursework part of the module, they will be able to apply fundamental (analytical and numerical) methods of non-linear dynamics to analyse chaotic systems and will appreciate the concept and the benefits of chaos control.|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills
Overall student workload
Independent Study Hours: 117
Lecture Hours: 33
Methods of Teaching / Learning
28 hours of theory lectures plus 5 hours of class exercises session (33 hours of lectures in total) and open-ended study for the coursework problems.
Exercises will be held in the form of tutorial sessions and are meant to demonstrate specific examples and applications of the material taught in class.
The coursework focuses on specific non-linear system(s) that give the student with opportunities to gain knowledge of advanced topics and to prove independent thinking, investigation and computational skills. The assignment is handed out mid-semester and typically requires the use of computational techniques such as non-linear differential equation solving, with the results to be presented in report form at the end of the semester (usually in week 12).
There final examination is 90 minutes in duration and two out of three questions should be answered.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
