2. Some Engaging Videos
• Quarks. The 'PhysicsGirl' youtube website has a cute 4 min video on the quarks in a proton. The content goes further than our course, but it shows that our picture of particles gets curiouser and curiouser, the deeper you look. Check also her website for her other videos, . The 'Stacked ball drop' is a good topic for a practical investigation, it is in 'Everyday physics'. The 'Space and the Universe' has 9 videos.
• Rocket powered bicycle reaches 333 kph in 4.8 seconds.
• Tennis racket effect: A spinning wing nut in an orbiting spacecraft suddenly flips about its axis of rotation. (Video is in Russian, demo occurs 30 seconds in, but some online discussion of explanation) and ( A demo with a table tennis bat)
• World's Simplest Homopolar motor.
• Direct Measurement Videos: This website, is devoted to videos in which students can extract data. Some of the videos are shot at high frame rates. The website has pages on 'What are DM videos?', 'Why teach with them?' and 'How to teach with them?' . There are over 60 videos mainly on Mechanics. There are also detailed teacher notes for each activity.
• US Physics Teacher, Dan Fullerton has compiled an extensive range of videos (877 in number) from various sources including Veritasium, Sumner Miller and Acapella Science. They are categorised by physics topic.
3. Friends of CSIRO: Meeting and Petition
The inaugural meeting of Friends of CSIRO Victoria will be held on Monday 2nd May at the CPSU offices, level 10/440 Collins St, Melbourne at 6pm. A copy of the draft charter is below.
There was a forum in Canberra last week that received some coverage on ABC Lateline, which can be seen on iView.
A petition on the cuts to the CSIRO has been set up, it can be signed at
The draft agenda for the Monday 2nd May meeting:
* Welcome and introductions
* Progress with establishment of Friends of CSIRO
* Actions to Oppose the CSIRO Cuts - possible forum, rally? Identification of margins seats.
* Actions to formalise the Friends of CSIRO
Draft Friends of CSIRO Charter
The Commonwealth Scientific and Industrial Research Organisation (CSIRO) is a critical component of Australia’s research and innovation capacity. The public good research it undertakes contributes enormously to Australian society and a secure future for Australians. Few other organisations undertake the range of scientific long-term research undertaken by CSIRO or give the return on investment to society as does CSIRO.
CSIRO has a long list of successful research outcomes contributing to important developments in medicine, ecosystem management, plant and manufacturing industries and other sectors. It is greatly valued by Australians.
Objectives of Friends of CSIRO are to:
• Oppose the job and funding cuts, actual and proposed, of the Abbott/Turnbull government;
• Promote the work of CSIRO to the community and government, in particular, public good, long-term research;
• Promote an understanding of science and the value of science to the community;
• Support the adequate resourcing of CSIRO to enable the fulfillment of its charter;
• Acknowledge that the crisis of climate change presents particular challenges to all sectors of Australian society and this challenge must be recognised by adequate resourcing of CSIRO, reflecting the scale and urgency of this challenge.

b) Maths, IT and Engineering, 11am - 2pm, Friday, 6th May, Monash University
The Faculty of IT at Monash University invites students, teachers and the general public to its Claude Shannon Centenary Celebration on Fri 6 May 2016, from 11am-2pm, in lecture theatre S14 at the Clayton campus.
Abstract: Claude Shannon (1916-2001) was a mathematician and engineer, one of the most remarkable in the 20th century. He was one of the founders of the information age, in that he laid down the mathematical foundations of efficient, reliable and secure communication, in the presence or absence of noise or eavesdroppers. He was also a pioneer in the mathematical analysis of switching circuits and in programming computers to play chess, among other contributions.
The celebration consists of a series of short talks, aimed at a general audience, followed by lunch. Talks include:
• Jamie Evans (UoM): Claude Shannon's life and career
• Michael Brand (FIT, Monash): noiseless coding
• Yi Hong (ECSE, Monash): noisy coding
• Ron Steinfeld (FIT, Monash): Shannon and Cryptography
• Reza Haffari (FIT, Monash): Shannon and natural language
• Rebecca Robinson (FIT, Monash): the Shannon capacity of a graph
• Graham Farr (FIT, Monash): Shannon's switching game
• Amin Sakzad (FIT, Monash): data compression
The event is free but registration is essential. To register, go to
For further information: contact Prof. Graham Farr, Graham.Farr@monash.edu, 0409 942 922.
c) Heavy elements in Red Giant Stars, 6:30pm, Friday 20th May, Swinburne University
Speaker: Dr Amanda Karakas from Monash University
Abstract: Most of the elements in the periodic table heavier than hydrogen and helium were forged in stars. Through the combined studies of stellar spectroscopy, nuclear physics, geochemistry, and astrophysics, humans have been able to work out the origin of many of the chemical elements that naturally occur in our Solar System. We know for example that most of the oxygen in the air was forged in ancient supernova explosions, which are the end product of very massive stars. The carbon in our bodies was synthesised instead by stars covering a wide range of stellar masses, from solar-type stars like our Sun through to massive stars. The biggest mystery today concerns the origins of the elements heavier than iron. In this talk I will take you on a journey through the origin of the elements, with a special focus on where the heaviest elements in nature are formed. In order to do this, I will discuss some basics about the life cycle of stars, which is intimately connected to the story of the origin of the elements through the nuclear reactions that occur deep in their interiors.
Date: Friday 20th May 2016
Time: 6.30pm
Venue: Swinburne University, Hawthorn campus, ATC building, ATC101

6. Physics News from the Web
Items selected from the bulletins of the Institute of Physics (UK) and the American Institute of Physics.
Each item below includes the introductory paragraphs and a web link to the rest of the article.
a) Cool Saharan ants' silver hairs cause total internal reflection
b) Finding the Earth-bound evidence for supernovae in the galactic neighbourhood
c) How Hard Does The Sun Push On The Earth?
a) Cool' Saharan ants' silver hairs cause total internal reflection
A species of desert-dwelling ant is able to tolerate temperatures exceeding 50 °C because its body hairs act like prisms causing total internal reflection of light, according to the latest work from a team of physicists and biologists in Belgium. The researchers found that the hairs of the Saharan silver ant, Cataglyphis bombycina, provide a 10-fold increase in light reflection, prevent overheating and giving them their silver shimmer.
The Saharan silver ant is one of the most heat-tolerant animals on Earth. The insects can run across the sands of deserts in Egypt and on the Arabian Peninsula at midday, scavenging corpses of animals that succumb to the intense heat. Being able to tolerate temperatures above 50 °C allows them to forage during the hottest part of the day when most other animals, including predatory lizards, are sheltering from the heat.
b) Finding the Earth-bound evidence for supernovae in the galactic neighbourhood
The locations and timing of the closest supernovae to Earth, which took place within the last few million years, could be determined thanks to new studies of a specific isotope of iron. The research, carried out by two independent teams, suggests that two supernovae exploded within 330 light-years of Earth in the past 2.3 million years. The findings – which combine "deep-sea astronomy" with "galactic archeology" – hint at the possibility that the supernovae may have affected Earth's climate, leading to the Pleistocene geological epoch from which homo sapiens evolved.
Astronomers have long suspected that supernovae taking place in our galactic neighbourhood could have decided effects on our planet, possibly causing mass extinctions or global climate changes. Iron-60 (60Fe) is produced when a supernova explodes, and its presence in the Earth's deep-sea crust means that one or more supernovae have occurred within the last few million years.
c) How Hard Does The Sun Push On The Earth?
