LAGRANGIAN & HAMILTONIAN DYNAMICS - 2025/6

Module Overview

This module introduces fundamental concepts in analytical dynamics and illustrates their application to real-world problems. The module covers the calculus of variations, Lagrangian and Hamiltonian formulations of dynamics, Poisson brackets, canonical transformations and symplectic manifolds. The module also leads to a deeper understanding of the role of symmetries and conservation laws in dynamical systems.

This module builds on material from MAT1036 Classical Dynamics and lays the foundations for MAT3039 Quantum Mechanics.

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate:

• Understanding of subject knowledge, and recall of key definitions and results in Lagrangian and Hamiltonian dynamics.


• The ability to identify and use the appropriate methods to solve real-world problems in dynamical systems using the Lagrangian and Hamiltonian formalisms.

Thus, the summative assessment for this module consists of:

• One in-semester test corresponding to Learning Outcomes 1, 3 and 4.


• A synoptic examination corresponding to all Learning Outcomes 1 to 4.

Formative assessment

There are two formative unassessed courseworks over an eleven week period, designed to consolidate student learning. 

Feedback

Students will receive individual written feedback on both the formative unassessed courseworks and the in-semester test. The feedback is timed such that feedback from the first coursework will assist students with preparation for the in-semester test. The feedback from both courseworks and the in-semester test will assist students with preparation for the synoptic examination. Students also receive verbal feedback in office hours.

 

Module aims

• Introduce students to the Lagrangian and Hamiltonian formulations of dynamics.
• Enable students to understand the role of symmetries and conservation laws.
• Illustrate the application of various techniques for solving real-world problems in analytical dynamics.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

• Introduce students to the principle of least action, and Lagrangian and Hamiltonian dynamics.


• Provide students with experience of methods used to analyse real-world dynamical systems and solve for the dynamics using the Lagrangian and Hamiltonian formalisms.

The learning and teaching methods include:

• Three one-hour lectures for eleven weeks, with module notes provided to complement the lectures. These lectures provide a structured learning environment and opportunities for students to ask questions and to practice methods taught.


• Two unassessed courseworks to provide students with further opportunity to consolidate learning. Students receive feedback on these courseworks as guidance on their progress and understanding.


• Lectures may be recorded or equivalent recordings of lecture material provided. These recordings are intended to give students an opportunity to review parts of lectures which they may not fully have understood and should not be seen as an alternative to attending lectures.

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.

Other information

The School of Mathematics and Physics is committed to developing graduates with strengths in Digital Capabilities, Employability, Global and Cultural Capabilities, Resourceness and Resilience, and Sustainability. This module is designed to allow students to develop knowledge, skills and capabilities in the following areas:

Digital Capabilities: The SurreyLearn page for MAT3008 features a dynamic discussion forum where students can pose questions and engage with others using e.g. LaTeX and MathML tools. This enhances their digital competencies while facilitating collaborative learning and information sharing.

Employability: The module MAT3008 equips students with skills which significantly enhance their employability. The mathematical proficiency gained will hone their critical thinking and problem-solving abilities. Students will learn to interpret and evaluate physical real-world problems in dynamical systems, model these mathematically using ordinary differential equations, and hence deduce and interpret solutions. Mathematical modeling is a highly sought after skill in many professions.

Global and Cultural Capabilities: Students enrolled in MAT3008 originate from a variety of countries and have a wide range of cultural backgrounds. Students are encouraged to work together during problem-solving teaching activities in lectures, which naturally facilitates the sharing of different cultures.

Resourcefulness and Resilience: MAT3008 is a module which demands the ability to analyse physical real-world problems in dynamical systems, formulate and solve these problems mathematically using the Lagrangian and Hamiltonian formalisms, and interpret the results. Students will gain skills in analysing unseen problems and lateral thinking, and will complete assessments which challenge them and build resilience.

Sustainability: The Lagrangian and Hamiltonian formalisms can be used to model dynamical systems relevant to sustainable practices. For instance, Lagrangian dynamics can be used to model the dispersal of pollutants and greenhouse gases in the atmosphere, which has an impact on climate change, and the dispersal of contaminants in bodies of water, which has an impact on water quality management. One or more case studies will be included in the module relating to uses of Lagrangian and Hamiltonian dynamics to model systems relating to real-world sustainable practices.
