Vicphysics Teachers' Network Inc.
Dear *|FNAME|*,

There are a few overseas physics education journals that feature links to websites with useful resources.  This newsletter includes a selection of those found in the last week.

Also coming up next week is the Physics Teachers' Conference.  The Chief Assessor's Forum is a month later in early March and the Beginning Teachers' In-Service is in the school holidays.


The next meeting of the Vicphysics Teachers' Network will be on Thursday, 7th February at Melbourne Girls' College starting at 5:00pm. Teachers are welcome to these meetings. If you wish to come, please email Vicphysics

Frances Sidari (Pres), Jane Coyle (Vice-Pres), Dan O'Keeffe (Sec) and Terry Tan (Treas)

1.  PhyPhox: Smart Phone Experiments
PhyPhox is an app produced by the Aachen University in Germany.  It can be downloaded for free.  The software makes use of the large range of sensors now in smart phones.  You can export your data in most common formats and also control any experiment remotely from a web browser.  There is also a 'forum' with numerous contributions.

2. Parallel Pedagogy: Learning the concepts simultaneously - Introductory mechanics
This curriculum resource adopts a teaching approach similar to the way we learn our first language. 'We just start using it while increasing complexity through iteration. Most every sixth grader can distinguish energy, momentum, force, and motion. Parallel Pedagogy begins there; stresses concepts, problem solving and picture drawing; while adding maths only as it becomes necessary.'
The material is produced by Pete Schwartz, Professor of Physics at California Polytechnic State University.
The website has an introductory video in which Pete Schwartz explains his methodology and the use of the flipped classroom. There is also a link to an article from 'The Physics Teacher' about the program.  He also has an extensive list of short instructional videos.


3.  Why a tennis ball goes flying when bounced on a basketball? Software to investigate the impact
An article in Wired by Prof Rhett Allain of Southeastern Louisiana University explains the high rebound of the tennis ball, along with a video, but more usefully he includes the code for a computer simulation of the impact.  You are able to not only run the simulation, but also, adjust the ratio of the masses to investigate the effect.  He also extends the software analysis to a multiball collision (Check out 'Astroblaster' the commercial toy).  There are a set of homework exercises at the end of the article.  Also check out Physics Girl Youtube video

4. Equipment Designs for Physics Demonstrations
This is a set of instructions to build equipment for over 50 physics demonstrations. They were prepared by John Johnston of The Faraday Centre in New Zealand.  The instructions require basic workshop tools.  The demos cover mechanics, waves, light and electromagnetism.

5.    Events for Students and the General Public
a) Monday, 11th February, Girls in Science Webinar, 10:20am - 11:30am AEDT

c) Friday, 22nd February, Things that go bump in the night: fast radio bursts and the search for life beyond Earth, 6:30pm, Swinburne University
Speaker: Dr Daniel C Price, Centre for Astrophysics and Supercomputing, Swinburne University
Venue: Swinburne University, Hawthorn campus, ATC building, ATC101 (Enter from Burwood Road)
Map: http://www.swinburne.edu.au/media/swinburneeduau/about-swinburne/docs/pdfs/hawthorn-map.pdf
Abstract: Thanks to new, more powerful technology, astronomers can search the skies faster and with more resolution than ever before.  In this public lecture, I will talk about two exciting fields in astronomy: the Search for Extraterrestrial  Intelligence (SETI), and Fast Radio Bursts. The SETI field has been reinvigorated by the 10-year, $100M Breakthrough Listen initiative to search for intelligent life beyond Earth. As a project scientist for Breakthrough Listen, I will introduce the program and detail how we are using new technology to run the most comprehensive search for intelligent life beyond Earth ever undertaken. I will also discuss a mysterious phenomenon known as fast radio bursts: incredibly bright but short-lived signals from distant galaxies, which escaped detection until recently. Could these signals be due to intelligent aliens, or is there an astrophysical explanation? I will give an overview of how a telescope upgrade will help us answer this question, and how Swinburne astronomers will play a leading role. Finally, I will discuss what evidence would convince us that there is indeed life beyond Earth, or that the Universe is ours alone to enjoy.

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

a)  Newton: Egomaniac or troubled genius? A review of 'Isaac Newton: The Asshole who reinvented the Universe'
Andrew Robinson reviews the book by Florian Freistetter
.  Albert Einstein’s final interview, two weeks before his death in 1955, was preoccupied with Isaac Newton, whose physics Einstein revered, next only to that of James Clerk Maxwell. But when the interviewer, an American academic historian of science, touched on Newton’s personality, and particularly Newton’s notorious refusal to publish any acknowledgement of the ideas of Robert Hooke in the preface to his Principia Mathematica (1687), Einstein responded: “That, alas, is vanity. You find it in so many scientists. You know, it has always hurt me to think that Galileo did not acknowledge the work of Kepler.” Later in the interview, Einstein added with a booming laugh that a man might often say that he had no vanity, but this too was a kind of vanity because he took such special pride in the fact. “It is like childishness,” said Einstein. “Many of us are childish; some of us more childish than others. But if a man knows he is childish, then that knowledge can be a mitigating factor.”
b) Fascinating Physics Facts about Snow Flakes
This is a Perimeter Institute (PI) has put together 14 fascinating Physics Facts about Snow Flakes.  At the end of the article, there is a videolink to a 57 min PI lecture on the Secret Life of Snow'
c) The Physics of Knitting
What do earthquakes, robotics and jumpers have in common? Samuel Poincloux explains why the answer lies with knitting – and how stretching a knitted material is rooted in mechanics

If you’ve ever done a PhD in physics, you’ll know you usually begin by ploughing through lots of background reading, learning how to use your lab’s equipment and maybe even carrying out some provisional experiments. My PhD was a bit different. I started off watching YouTube videos to improve my needlework.

The project I had accepted at the Ecole Normale Supérieure in Paris was about the mechanics of knitted fabrics. The research was to have two sides: a theoretical one to determine what equations described the system; and an experimental one to mechanically test actual knits to guide and verify the theory. The trouble was, I barely knew what a knit was when I accepted the project.

I quickly learnt that there are differences – both structural and mechanical – between a knit (such as a jumper, scarf or hat) and a weave (such as a table cloth, shirt or pair of jeans). In fact, those differences are easy to demonstrate. If you pull on your jeans, you should notice that the weave hardly deforms. Pull on a knitted jumper, in contrast, and it can be effortlessly elongated by up to two times its length. The stretchiness of a knit is also obvious if you wrap it around something: by locally stretching, a knit can fit complex shapes; a woven fabric, however, has to fold to conform to it.
