Physics


The discipline

Physics is a major branch of modern science that provides a basis for an understanding of the physical world. Many of the important methods and techniques found in other branches of science and technology owe their existence to the practice of physics. The discipline of physics ranges from the very practical, such as an explanation as to why an integrated circuit works, to fundamental philosophical questions about reality. A program of study in physics provides a sound scientific background for today's complex and technologically oriented world.
Both observation, measurement and data analysis are essential in physics as in many areas of scientific endeavour. Therefore, with the exception of third and fourth-year theoretical physics, all physics subjects involve laboratory work where the emphasis is on instrumentation, data collecting and analysis. As well as those students who major in physics, there are many who need a foundation in physics as a prerequisite or recommended subject for their later-year studies. The department also provides subjects in materials science at both second and third-year levels, and in astronomy at both first and second-year levels.
Undue specialisation is avoided in the first three years (to pass BSc). In subsequent years (BSc honours, MSc, MAppSc and PhD), opportunities exist for specialisation within each of the fields of theoretical physics, experimental physics, astronomy and astrophysics, applied physics and materials science. For details of materials science, see separate entry. The astronomy subjects and discipline details are also found under a separate entry for astronomy and astrophysics.

Discipline structure

First year

Director of first-year studies: Dr David Mills
Two first-year physics sequences are offered - PHS1011 and PHS1022 (Physics) and PHS1031 and PHS1042 (Physics for bio- and environmental sciences). The physics sequence PHS1011 and PHS1022 covers the foundations of physics over two semesters, providing a balance between a theoretical understanding of physics along with practical applications and experimental physics. This sequence follows a mathematical approach using calculus and a Year 12 Physics background is assumed. This sequence is normally taken by students with interests in physics, mathematics, astrophysics, chemistry, computer science, those interested in the nature of the universe, and those doing science/engineering double degrees.
PHS1031 (Physics for the living world) and PHS1042 (Physics for bio- and environmental sciences) are specifically designed for students interested in biomedical and environmental disciplines. There is an emphasis on applications of physics principles and instrumentation in the modern biosciences. The approach is more descriptive than the former sequence and can be undertaken by students with no previous physics.
Both PHS1011 and PHS1022 are normally required to enter the second-year physics subjects PHS2011 and PHS2022, however students with exceptionally good results in PHS1031 and PHS1042 may be enrolled at the discretion of the head of department. Either first-year sequence provides an adequate foundation to continue to second-year studies in astronomy and materials science as well as providing a strong experimental background for students whose principal interests are in other branches of science. Students entering second-year physics should have done sufficient first-year mathematics to undertake MTH2010.
A group of physics and physical science subjects is also offered at first-year level on the Gippsland campus: PHS1616, PHS1627 and PHS1639.
The department also offers first-year astronomy ASP1010 (Earth to cosmos - introductory astronomy). See separate entry under 'Astronomy and astrophysics' for details.

Second year

There are three major subject groupings, or streams, taught by the Department of Physics in the BSc at second-year level:

Physics
Astronomy
Materials science

These streams are designed to provide a good grounding in the various aspects of physics for students wishing to major in other disciplines as well as those intending to continue to third-year physics and beyond. All second-year physics subjects comprise three hours of lectures/problem classes/tutorials per week and four hours of laboratory work per week.
Students intending to proceed to third-year physics and/or theoretical physics must pass PHS2011 and PHS2022. The additional six-point subject PHS2510 (Medical physics) is available for students wishing to undertake more than 12 points of physics at second year. This subject complements the other physics subjects and provides an understanding of the physical principles underpinning modern medical imaging. This subject is recommended but not essential for students who intend to continue to third-year physics. Alternatively, the subjects PHS2211 (Astronomy: exploring the solar system), PHS2222 (Astronomy: the stars and beyond), PHS2611 (Everyday materials) and PHS2622 (Functional materials) are available to increase the number of physics points taken at second year.

Physics

Second-year physics coordinator: Dr Greg Jakovidis
The subjects PHS2011 and PHS2022 each comprise three theory units and are designed to introduce some of the underlying principles of physics, including quantum physics, solid state physics, electromagnetism, optics and atomic and nuclear physics. The need to keep abreast of aspects of instrumentation and electrical and electronic measurements is covered by the analogue electronics and AC theory units. The key concepts of each theory unit are linked via common applications in the areas of quantum concepts and technologies (PHS2011) and physics for communications and measurement (PHS2022). Students intending to proceed to third-year physics/theoretical physics should also take the six-point second-year mathematics subjects MTH2010 and MTH2032.

Astronomy

Astronomy coordinator: Professor John Pilbrow
The Department of Physics operates its own observatories at Mount Burnett and at the Clayton campus. The two subjects ASP2011 and ASP2022 cover both theoretical and observational astronomy. For details of these two subjects, see 'Astronomy and astrophysics'.

Third year

Three subject sequences are offered by the Department of Physics at third-year level - physics, theoretical physics and applied physics.

Physics

Third-year physics coordinator: Dr Trevor Hicks
Third-year physics subjects are offered either as 12 or 24-point semester subjects. In both cases, the subjects are made up of a specified number of units (some compulsory). Each unit normally comprises 12 one-hour lectures. The 12-point physics subjects PHS3031, PHS3042, PHS3051 and PHS3062 comprise four 12-hour lecture units, one six-hour unit, 12 tutorials plus five-and-a-half hours of laboratory work on average per week for the semester. The 24-point physics subjects PHS3011 and PHS3022 have eight 12-hour lecture units, one six-hour unit, 24 tutorials and 11 hours of laboratory work on average per week. In all these subjects, the choice of units must be approved by the coordinator. As part of the laboratory work, students attend a six-hour professional studies unit in each semester. These units provide an important introduction to the role of a professional physicist. During the year students will visit an industrial, research or medical physics laboratory.
Two physics project subjects, PHS3351/PHS3352 (four points) and PHS3360/ 1/2 (eight points), are available to allow students to work individually on a project of their choice with a staff supervisor.

Theoretical physics

Third-year theoretical physics coordinator: Dr Trevor Hicks
The 12-point theoretical physics subjects PHS3131 and PHS3142 comprise six 12-hour theory units and 18 tutorials.

Applied physics

Third-year applied physics coordinator: Dr Trevor Hicks
Applied physics at third-year level comprises two subjects - PHS3331 and PHS3342. These two subjects, each of four 12-hour units, one six-hour unit, 12 tutorials and five-and-a-half hours of laboratory work on average each week, maintain a theme of instrumentation and monitoring, emphasising frequency domain signal processing, the extraction of signals from noise, and the application of instrumentation to measurements in a number of physical fields.
The requirement for entry to honours year applied physics is a pass in both PHS3331 and PHS3342 at an average of a distinction level.

Fourth year

Fourth-year physics coordinator: Dr Andrew Smith
At the honours level, physics offers three subjects - PHS4000 (Experimental physics), PHS4100 (Theoretical physics) and PHS4200 (Applied physics). Students wishing to proceed to fourth year should apply towards the end of their third year. Normally, a distinction or a higher grade at third-year level is required. All students are assigned an individual supervisor. All three subjects consist of lecture units and a research-oriented project.
Students may commence honours studies at either the beginning of the year or at mid-year. For both groups of students, lectures are conducted in first semester and the research project undertaken in second semester. By arrangement with their supervisor, a student may undertake a limited amount of coursework in second semester, but it is intended that the research work be carried out without distraction from other activities.
Thus, students commencing at the beginning of the year complete all (or most) of their coursework in first semester and undertake the bulk of their project work in second semester. They are normally required to begin their studies during the first week of February. Those students entering at mid-year carry out their project in the second semester of that year and complete all (or most) of their coursework in the first semester of the following year. They are expected to begin their honours studies by the start of second semester.
The lecture units are only offered in first semester, and each unit comprises approximately 18 hours of class contact. Students are required to choose lecture units in collaboration with their supervisors. Students enrolling in PHS4000, PHS4100 and PHS4200 must note the compulsory units under the relevant headings.
Not all fourth-year units listed may be offered in any one year. In special circumstances, some variation in the compulsory units listed may be permitted. Students may include units at an appropriate level from those available in other departments of the university. Students who have taken units offered at both third and fourth-year levels, as part of their third-year study, may not repeat those units at honours year.
