Huge Music News

CBC Music are thrilled to announce that, as of next semester, our music tutors will be fully fledged members of the CBC Staff.

Whilst there are many familiar names officially joining our department, there are some new faces as well:

• Mr Billy James – Percussion
• Ms Nikki Poznak – Piano
• Mr Sam Peng – Piano/Brass
• Mr Peter Morrey – Piano
• Mr Luke Thompson - Voice
• Ms Nicola Beveridge - Woodwind
• Mr Will Madden – Brass

This illustrious group will join Mr Robin Pratt and Mr Jude Thursby to complete our Terrific Tutoring Team.

More information has been sent to families already engaged in the music program; however, if you’d like to know more or wish to become part of the CBC Music Community, please reach out via music@cbc.sa.edu.au.

As part of this process, we bid farewell and thank the following tutors for their involvement: Mr Andras Tuske (guitar), Mr Ian Boath (brass), Mr Jamie Adam (percussion) and Mr Grant Gillespie (piano).

Debating

Congratulations to the mighty Year 8 and 9 teams for their Round Three victories!

Intermediate A – Rupert, Tirath, Annicet, Jasper

This was Annicet’s first-ever debate!

Intermediate B – Andrew, Bailey, Jacob, Thomas.

Unfortunately, Year 6 and 7 teams had the narrowest of losses, and Year 10 had to forfeit due to illness.

Music Tour

Just a couple more sleeps until we hit the road!

We will be taking plenty of photos and videos, and are hoping to post some along the way so that you can follow us through the Riverlands.

Thanks in advance to Mr Roach, Mr Pratt, Mr Thursby and Dr Del Col for their participation in this trip, and especially to Mr Sheehan for his organisation!

Drama Club

Last newsletter, we asked you to save the date for Monday 11 August. Due to a clash at the Star Theatre, we have had to push out a week, so feel free to enjoy 11 August, but save 18 August for us!

Astronomy Club

In our last report, we left you with some strange photos and asked you some questions, a nice segue to this write-up. Trying to reproduce photos in a report like this is paramount to capturing a map of Australia onto a postage stamp and then trying to describe the details in the cities. Recall that the project we are working on is capturing Centaurus A, a galaxy 13,050,000 light years from Earth (1 light year is 9,460,730,472,580. 8 km, so 13,050,000 × 9,460,730,472,580. 8 km from Earth). As a reference, remember that the Earth at its widest point is 12,756 kilometres wide; therefore, we could fit 9,678,781,174,912,154 Earths between us and Centaurus A. So, it is fairly remarkable that CBC’s telescope, in the most light-polluted part of Adelaide, its centre, has its lens trained on an object so distant, totally invisible to the human eye, and can still produce some sort of result. We have come a long way since the days of Hans Lippershey & Zacharias Janssen and Jacob Metius in 1608 who created the first telescopes (independently).

Back to our monochromatic photos and the questions posed …

We have started to layer all our images. This allows us to see more detail. When we layered all our luminance photos (approximately 5 hours of photos), this is the image we ended up with (still not coloured, that is our next step).

One of the interesting features about the galaxy Centaurus A is the supermassive black hole at its centre. It projects a jet of high-energy particles from intense gravitational and magnetic fields around it. Its jet is so powerful, it's moving at nearly the speed of light.

As always, questions can be sent through to me at any time.
