The John Mainstone Youth Lecture Tour 2018, Queensland

This year’s youth lecture tour will promote physics to senior high school students and science teachers. Commencing in August, Dr Sean Powell and Dr Jacqui Romero will present lectures in Physics to high school students in major centres across the state.


The 2018 AIP Lecture Series will be delivered by Dr Sean Powell.


Dr Powell’s talk in 2018 is titled Physics is everywhere! – a journey from sub-atomic particles to the large-scale structure of the universe, where physics seeks to answer the most fundamental questions about reality. As we learn more, we can do more! Physics is everywhere in our world and underpins all our technologies. This year, Sean will discuss the important problems that all of us encounter every day: how do I teleport myself to school? What do I do when I find myself inside a black hole? Why is my time-machine not working? He will also talk about the superpowers that you can gain as a physicist, such as the ability to make accurate quantitative observations and predictive and interpretive mathematical models.  These powers mean that you can become very valuable and work in many industries such as fundamental physics research, economics and finance, space and aeronautics, healthcare and medicine, learning and teaching, electronics and computers, and so much more!


An additional regional lecture will be delivered in Mount Isa in 2018 by Dr Jacqui Romero.


Dr Romero’s talk in 2018 will focus on Slower light in free space. The speed of light is nominally given by c/n, where n is the refractive index of the medium in which the light is travelling.  The refractive index of free space is 1, hence it is natural to expect that in free space, light travels at c. We show that this is not the case when you consider real beams.

We consider photons in a Bessel mode and a focused Gaussian mode, and show that in both cases, the reduction in group velocity results to a delay of several micrometers over a propagation distance of 1 m or ~30 femtoseconds in terms of arrival time.

Please refer to the attached itinerary for information regarding dates, times and venues and contact details for the host at each venue.

AIP 2018 Youth Lecture Itinerary Brief

There is no cost to attend these presentations; however, we do ask that you RSVP the organiser at each venue to indicate your school details, staff attending and anticipated student numbers , by Wednesday 25 July.


We would appreciate your assistance in forwarding this to any interested staff and students who may not receive it via the Physics Discussion list.
