1.  Call for Conference Presenters for 2020 Physics Teachers’ Conference.
We invite you to consider presenting a workshop for your colleagues at next year’s Physics Teachers’ Conference. We all have much to share. The conference will be on Friday, 14th February at La Trobe University.

A distinctive feature of the Physics Teachers’ Conference over the years has been the large number of teachers who offer workshops about what they do.  These workshops are not only beneficial for other teachers, but they also significantly enhance the curriculum vitae of the presenters and their own personal skills. With the new course bedding down, the conference is an ideal forum for you to share your ideas on teaching the new content and the different ways of assessing.

If you would like to offer a workshop, please register the workshop on the STAV website, here.  Theclosing date for registrations is Friday, 20th September.

  • The presenter and only one co-presenter are free of charge for the session they are presenting.
  • All such presenters are able to register “free of charge” for other sessions at this conference.
  • All subsequent co-presenters are charged $75 each and need to register to attend sessions.
  • Presenters are not paid any fee nor is CRT covered.

3. National Science Week Events

4. Participation in VCE Physics: Trends and Projections
The number of students doing VCE Units 3 & 4 has been about 7500 for the last few years. Based on current trends and the number of students now in primary and secondary schools, this number should reach 8500 in 2024 and 9500 in 2030.
A full analysis is provided on our website here , but key aspects are covered below.
Student numbers at Year 12 are affected by population changes and changes in the retention rate (i.e. the percentage of Year 10 students who stay on to Year 12).  To get a meaningful measure of the intrinsic popularity of the subject, it is better to express the number of physics students as a percentage of the age cohort and see how this has varied over time.

The graph on the right shows much variation over the years.  There is a noticeable spike in 1992 coinciding with the introduction of the VCE.  Much political discussion on science education focusses on the decline post 1992, but research on the increase pre 1992 may be more fruitful.

Graphs of the proportion of Year 10 students who do Year 11 Physics the following year and the proportion of students doing Unit 2 who do Unit 3 the following year, both reveal interesting data.  The percentage of Year 10 students choosing to do Unit 1 Physics in Year 11 has been slowly declined from 1996 to 2010 with some levelling out since then.  This drop off has been somewhat countered by an increase of the retention from Unit 2 to Unit 3.


The projected student numbers to 2024 and 2030 are based on current student numbers from Foundation Year to Year 11 and assume the current participation rate of the age cohort is unchanged.

e) 28th August: Girls in Physics Breakfast at Monash University

This is our fourth year of running Girls in Physics Breakfasts. The aims of the program are:

  • to encourage girls in Years 10 to 12 to appreciate the diversity of careers that studying physics enables,
  • to appreciate the satisfaction that comes from a challenging career in science, and
  • to be aware of the success that women can achieve in the physical sciences.

The one remaining Breakfast for this year is on 28th August at Monash University, Clayton campus, see details below.
At each breakfast, students share a table with two or three women who are either have a career in physics or engineering, or are at university as undergraduates or postgraduates.  At the table, discussion ensures about what the women do, what they like about it as well as their training, future prospects, etc.  As a student at one of  early breakfasts told her teacher, ‘I was talking to a guest at my table and her career sounded so amazing.  Then I realised that in 8 years that could be me.  I got so excited.

There is also a guest speaker at each breakfast who presents a talk on her area of expertise.  After the talk there are activities on Careers in STEM and Q & A panel with three of the guests.

The date, venue, speaker, topic and Trybooking link is:

  • 28th August, Clayton Speaker: Dr Helen Maynard-Casely, ANSTO. Topic: How neutrons can save the world. Closing date: 4:00pm, 19th August.  Trybookings.

Further details: For promotional flyer and more details on the talk, etc, go to our website.
Numbers:  There is an initial maximum of  6 students per school, to ensure that more schools that can participate. On 8th August, extra spots will be opened up to schools that have already booked.
Cost: $15 per student with teachers free, a discounted fee is available to schools with a low ICSEA rank.
See the specific Trybookings link for details.

7.   Physics from the Web
Items selected from the bulletin of the Institute of Physics (UK).
Each item below includes the introductory paragraphs and a web link to the rest of the article.

New device excels at making hydrogen using concentrated sunlight

The large-scale and renewable production of hydrogen could soon be possible thanks to a new photoelectrochemical device that is driven by concentrated sunlight. When scaled-up, the technology could revolutionize how hydrogen is produced and make the gas a viable alternative to fossil fuels.

Sunlight and water are both in great abundance on Earth so using light to split water molecules to create hydrogen fuel has great potential for creating a clean and renewable energy source. Now mechanical engineers at the Swiss Federal Institute of Technology in Lausanne (EPFL), led bySophia Haussener, have created an electrochemical device that uses concentrated solar radiation to create hydrogen fuel from water with no undesirable byproducts.

Summer weather extremes linked to stalled Rossby waves in the jet stream

Early summer heatwaves in Western Europe and North America set new temperature records in 2018, while other regions of the northern hemisphere were hit with torrential rain and severe flooding. Now researchers in the UK, Germany and the Netherlands say that these events were linked by a pattern of stalled waves in the jet stream. They add that this wave pattern appears to have increased in frequency and persistence in recent years and may occur more frequently in the future due to climate change.

The northern jet stream is a river of fast-moving air that circles the northern hemisphere in the mid-latitudes. Travelling from east to west at an altitude of around 10 km, these winds drive large-scale weather systems around the globe.

Jet-stream winds generally travel at the same latitude, but they can shift into a wave-like pattern, known as Rossby waves, where they meander from north to south and back again. When this happens, warm air fills the peaks of the wave, while cold polar air drops into the troughs. Rossby waves normally continue to move from east to west – shifting high- and low-pressure weather systems with them. However, they can also stall – which can lead to heatwaves, droughts and floods as the regions of hot and cold air hover over the same regions for days, or even weeks.

QB or not QB – that is the question for quantum physicists and philosophers
Philosophers can learn much from a row in the physics community, says Robert P Crease.  “It is a bad sign,” the Nobel-prize-winning theorist Steven Weinberg wrote recently, “that physicists who are most comfortable with quantum mechanics do not agree with one another about what it all means.”

Well, that’s Weinberg’s view. I don’t find those disagreements a bad sign – just a sign that philosophical issues are in play. Yes, quantum mechanics is full of puzzles. Is, for example, the wave function real or a book-keeping device? What does “reduction of the wave function” mean? And if the many-worlds idea is untestable, can it be true?

The meaning of quantum mechanics is made even more perplexing by several thought experiments that seem to reach impossible results. One is “Wigner’s friend”, in which an observer of a quantum measurement and an observer of that person are shown to make different statements about the quantum state being measured. Another is Schrödinger’s cat, in which quantum mechanics declares an unobserved feline to be half-dead, half-alive.
