2. Other Physics PD in 2020
a) There will be a Beginning Physics Teacher In-Service on Tuesday, 31st March at Kew High School. Click here for more details and to register.
b) There will be a Workshop for Lab Techs on Physics in Years 7 – 10 on Monday, 14th September at Camberwell Grammar School, organised in association with Camberwell Grammar School. Click here for more details.
The solutions are written for students to use when doing the exam paper for revision. A suggested marking scheme is included.
At the end of the solutions there are additional questions that use the stem from many of the questions in the paper. In particular there are several extra questions on Question 19a, which only covered a limited set of the skills students are expected to use in their Unit 4 Investigation.
4. Why a tennis ball goes flying when dropped with a basket ball – An article with simulations
Dropping a tennis ball and basket ball together with the tennis ball on top is not only an impressive demonstration, it is an excellent topic for a Unit 2 or Unit 4 practical investigation.
Rhett Allain, professor of physics at North Carolina State University and a regular columnist in online magazine, Wired, has written an article on the phenomenon, which also has videos, graphs and a simulation written in glowscript, where the reader can edit the code.
5. Seeking a Physics Teacher? Seeking a job?
Last year Vicphysics Teachers’ Network set up a Job Ads page on our website to assist schools in finding a physics teacher, either to be a LSL replacement or to fill an ongoing position or just to cover an extended sick leave. Several schools placed notices.
The web page also lists the Government schools seeking a physics teachers, currently there are three. This web page will be updated every weekend.
The webpage also has a link on how schools can register a position and also lodge a payment for this service.
a) The unintended humour of the Universe, 7:00pm, 29th November, Swinburne University
A special End of Year Lecture in ATC101. Scientific research is not only fun but also funny. In this end of the year talk, Dr Tiantian Yuan explains how the universe makes us laugh and think. For more details and to book, click here. Audio recordings of lectures in this series are also available at this link.
Dr Tiantian Yuan is an Astro 3D Fellow at Swinburne University’s Centre for Astrophysics and Supercomputing.
Her research goals include understanding how galaxies like our own Milky Way assembled and evolved from young galaxies in the early universe. Her research takes up the challenge of directly resolving high-redshift galaxies to the finest spatial scale.
Her current ASTRO 3D project at Swinburne focuses on when and how spiral arms formed in the early universe. The formation of spiral arms is part of the unsolved puzzle of the origin of the Hubble sequence. Despite early successes in the 1960s-70s, the necessary and sufficient conditions of spiral arm formation are still unknown. Breakthroughs can come from observations of high-redshift galaxies, when spiral arms are in their earliest stage of formation.
Tiantian obtained her PhD from the University of Hawa’ii, and held a postdoctoral fellowship at the ANU before coming to Swinburne in 2017.
b) Physics Days at Luna Park: 3rd March – 6th March, 2020
The dates for 2020 are Tuesday, 3rd March to Friday, 6th March.
Bookings are open for next year’s Physics Days at Luna Park, click on ‘Events’. You can make a booking for a particular day this year and change your day once your timetable for 2020 is known. But please remember to notify Luna Park on any change of date at least a fortnight before the event.
An aerobatic display by a member of the Roulettes has been requested, but confirmation is often not provided before February next year.
The silly Serpent has been removed, two rides have been relocated and a new ride is being installed.
If you wish to book a Pasco data logger, please contact Ciderhouse directly.
An article that assesses the current state of play of renewables by Dave Elliott, Emeritus Professor of technology policy at the Open University, UK.
Shock waves fired repeatedly into water samples can remove dissolved salts, according to A Sivakumar and Martin Britto Dhas of the Sacred Heart College in Tirupattur, India. The researchers say that the effect involves a cavitation-based nucleation mechanism that could be useful for the pretreatment of water at desalination plants. However, not everyone is convinced by their findings.
A new refrigeration technology based on the twisting and untwisting of fibres has been demonstrated by a team led by Zunfeng Liu at Nankai University in China and Ray Baughman at the University of Texas at Dallas in the US. As the demand for refrigeration expands worldwide, their work could lead to the development of new cooling systems that do not employ gases that are harmful to the environment.
The cooling system relies on the fact that some materials undergo significant changes in entropy when deformed. As far back as 1805 – when the concepts of thermodynamics were first being developed – it was known that ordinary rubber heats up when stretched and cools down when relaxed. In principle, such mechanocaloric materials could be used in place of the gases that change entropy when compressed and expanded in commercial refrigeration systems. Replacing gas-based systems is an important environmental goal because gaseous refrigerants tend to degrade the ozone layer and are powerful greenhouse gases.
