||Relativity and Cosmology
||Dr D.K. Sing
||10 NICATS / 5 ECTS
||18 students (approx)
This module is an introduction to the special and general theories of relativity.
Although the course avoids the use of advanced mathematical topics and
emphasises the concepts behind the theory, students will require a good level
level of mathematical fluency and intuition in order to engage with material.
The module aims to develop an understanding of Einstein's Special Theory of Relativity. The General
Theory will also be introduced and applied to the standard cosmological model and
to the three historical tests of the theory: the precession of the perihelion of mercury,
the bending of light passing close to the sun and the gravitational red shift.
Intended Learning Outcomes (ILOs)
A student who has passed this module should be able to:
Module Specific Skills and Knowledge:
- give coherent explanations of the principles associated with:
special relativity, general relativity, and cosmology;
- interpret observational data in terms of the Standard
Model of the evolution of the universe;
- describe experiments and observational evidence to test the
general theory of relativity, explain how these support the
general theory and can be used to criticise and rule-out
- apply tensors to the description of curved spaces;
- solve problems by applying the principles of relativity;
- deduce the Friedmann equations describing the evolution of the Universe.
- explain what is meant by: intrinsic and extrinsic curvatures,
the curvature of space, local inertial reference frame, and
- describe world lines of particles and photons in a curved space-time;
- describe the Cosmological Principle and the Robertson-Walker metric;
Discipline Specific Skills and Knowledge:
- explain to non-specialists the basis of one of the corner-stones
of 20th century Physics;
Personal and Key Transferable / Employment Skills and Knowledge:
- locate, retrieve and evaluate relevant information from the WWW.
- meet deadlines for completion of work to be discussed in
class by developing appropriate time-management strategies.
