117 – Dr Michael Brown – Galaxy Evolution and Active Galactic Nuclei

I speak to Dr Michael Brown, from the School of Physics at Monash University. Michael talked to me about the formation of galaxies, and specifically, research into Active Galactic Nuclei (AGN)

– What is the definition of a galaxy?
– What makes up a galaxy?
– What are some examples of galaxies we can see with binoculars and telescopes?
– What is the difference between a galaxy, a cloud of gas and a globular cluster?
– What are the structures of galaxies?
– What do we know about how these different types of galaxies form?
– How do galaxies grow over time?
– Do we know where the central black holes in galaxies come from?
– What is an Active Galactic Nucleus?
– Are there different types of AGNs?
– How are quasars formed?
– Why do some galaxies have AGNs and some do not?
– Are AGN’s the mechanism that causes the formation of stars in galaxies?

Today’s listener of the episode is Robin Ford from Sydney, Australia.

108 – Is Intelligent Life Common in the Universe?

A question that everyone asks at some point is – are we alone? We’ve all heard about the Drake Equation, and have had chats about our place in the universe with friends.

In this episode, Dr Allie Ford hosts a debate between Professor John Lattanzio and Ms Marion Anderson from Monash University on the topic “Intelligent Life is Common in the Universe”. Ms Anderson argues for the positive, and Professor Lattanzio argues for the negative.

They both argue the topic using the latest information and theories about astronomy and the possibility of life existing in the Universe. In recent years we have found hundreds of planets outside the solar system. Surely intelligent life must exist somewhere. But why have radio searches revealed nothing yet?

Marion’s presentation for the positive argument
Prof Lattanzio’s presentation for the negative argument

097 – Dr Rosemary Mardling – Extra solar planets

I talk to Dr Rosemary Mardling, an astrophysicist from Monash University on the topic of extra-solar planets. Topics we cover include:

– What is an extra solar planet?
– How do we find extra solar planets?
– How do we estimate the size and form of these extra solar planets?
– How do we explain the “Hot Jupiter” style planets that have been found?
– Most extra solar planets that have been found are short period – why is this the case?
– Is our solar system “normal”, or unusual?
– How do we determine if a system has more than one extra solar planet?
– What could finding extra solar planets mean for us here in our solar system?

Also included in this show are the listener of the episode, and listener feedback.

Apologies for the audio quality of this interview – it’s been cleaned up as much as possible.

095 – Dr Andrew Prentice – The Saturn System

Dr Andrew Prentice from Monash University continues his discussion with me about his theories of the formation of the solar system. In this episode, we concentrate on the Saturniun system, satellites such as Titan and some of the observations in comparison to his predictions, and conclude by reflecting back on what was discussed in the previous two episodes.

This is the final part of a 3 part interview series with Dr Prentice. Please listen to episodes 93 and 94 first.

094 – Dr Andrew Prentice – Planets and Satellite formation

I continue my talk to Dr Andrew Prentice from Monash University, extending on the discussion in part 1 of this interview series on Supersonic Turbulence, to talk about the Modern Laplacian Theory, and how it helps describe planetary and satellite formation, and it’s weaknesses. The discussion on satellites, and especially Titan, is fascinating.

This is part 2 of a 3 part interview series.

085 – Marc West – The Science and Psychology of Cricket – Part 2

In this episode, I continue my discussion with science journalist Marc West. We talk about the psychology and science of sport – and the case study we use is cricket. The topics we talk about can apply to practically any team sport, but being the cricket fans we are, we relate it to the gentleman’s game. Topics we cover in this second part of our discussion include:

– Psychology and batsmen
– The psychology of Shane Warne
– The difference between on field and off field psychology
– Body language
– The usage of sports psychologists and counselling for the English team
– Life after a sporting career
– The similarities between professional sportsmen and retired soldiers
– Research into injuries and sports medicine
– Kinematic studies of the doosra and off-break deliveries
– Tracking the workload of cricketers using GPS
– A mathematical surprise about the statistics of the best batsmen in the game – Sachin Tendulkar, Don Bradman, and even Ricky Ponting! (in fact, the top 34 test run scoring batsmen) What is this revelation, and how could this revelation be true? Mathematics will show you the way…
– Is it harder to get Ricky Ponting out at 49 compared to 51?
– The longer a batsman stays at the crease, the harder it is to get him out, right? Wrong! Listen in and find out why…
– How does this relate to the exponential distribution and coin tosses?

Also featured in this episode is Listener of the episode, and listener feedback.

This is part 2 of a 2 part interview. Please listen in to episode 84 for the first part of the interview.
