Joe Wolfe: educational pages   New: Physclips Mechanics has won the Physics division of the 2007 Pirelli Prizes for Science Communication. Physclips uses animations and film clips to introduce basic ideas in mechanics. New: Physclips Waves and Sound is the new section and our latest project. The first chapter is up and we'll post more when they are ready. Relativity in brief - or in detail. Can relativity be understood by someone with little or no background in physics? "Einstein Light" uses animations and film clips to explain relativity at a range of levels. Review in Science; award from Scientific American.   I work in the School of Physics at the The University of New South Wales. With help from my colleagues John Smith, John Tann and George Hatsidimitris, I have written various educational web pages, of which this page is a partial catalogue. The educational pages are divided thus: Pages related to education and learning in general Pages on topics in physics Pages on sound, hearing, speech and music Miscellany Materials for high school teachers and students Materials for primary school teachers and students Teaching awards My main research is described in my scientific publications, but there are popular accounts in these areas: the acoustics of musical instruments, the acoustics of the voice coding for cochlear implants and cryobiology. I am also a composer and the next link is to some of my music for orchestra or for chamber music ensembles.

Pages related to education and learning in general

• How to write a PhD thesis. Strangely enough, this is a big hit. Either there are lots of students writing theses, or lots of people procrastinating.
• How to survive a thesis defence.
• Writing and publishing a scientific paper.
• Hints for doing tests. All obvious advice, but it may help.
• Disappointed with your results in your intro physics test? These study hints may help.
• Tips for giving talks: some basic tips written for students who may not have given talks before.

Pages on topics in physics
