Remember Prof. Millar? why is it so

A classic, from ABC science

Also remember his ads for Cadbury chocolate!!!:D

Here is one of his ads, always put a bit of science into it.

Dr Julius Sumner Miller a great tradition of making science interesting and accessible to kids!

His successor Dr Karl Kruszelnicki holds the Julius Sumner Miller fellowship in the Physics Department of Sydney University.

[bob10]

Yes, Dr Karl. Love listening to him. Bob

I also loved The Summer Science School with Prof Harry Messel.
I would never miss it.

Me too. Headed me towards a career in science


The Institute of Marine Science had a research boat named in honour of Harry Messel- It was fondly known as the "Hairy Mussel"

I would never miss it.Oh that's another name. Remember the NSW Government Schools science textbook by Harry Messel? Its one way to guarantee royalties on a book, make it the standard textbook for a curriculum. :D

Professor Messel worked the system. His conviction for 4 counts of poaching barramundi and magpie geese, was quashed several years later in the High court

I recall that after Prof Julius Sumner Miller showed everyone how to get an egg into a milk bottle that the milk suppliers had a problem of bottles returning with eggs in them or not enough bottles coming back. So Sumner Miller had to demonstrate on another episode how to get the egg out of the bottle.

Those were the days!

In my opinion, he was a great man.

That was the marvel of the Professor.

Couldn't drag me away from the tv when he was on, especially during the space race period!

Was Prof Julius SM in the PSSC series of 16mm films (mid 1960s-ish)? I seem to remember the comment about "What do you expect from the Inverse Square Law?" face on to camera, challenging the viewer to argue...


What a smart and delightfully engaging man!

As good as he was , he couldn't educate my thick skull.
In twenty words or less, how did that egg get into the bottle?

The force or pressure of the air pushed it in.

These ones are a little harder to explain:

I understand the force bit, but why didn't the egg shell crack?

[Mick_Marsh]

I understand the force bit, but why did't the egg shell crack?
Ah, yes. You need to get some perspective.
What you do is move the egg away from the bottle. The further away you move it, the smaller it gets. Eventually it gets small enough to drop in.
Now, here's the important bit. Drop it in gently or it will crack.
When it is in, move it back and it gets bigger again.

To illustrate what I mean, refer to the attached photographs.
You'll note the egg is not in the bottle as I moved the bottle closer to the egg which makes the bottle smaller. A mistake I'll not make again.

[mike123]

I understand the force bit, but why didn't the egg shell crack?

Hard boiled egg with shell removed. It conformed to the milk bottle neck as it was drawn down by the vacuum created as the bottle cooled.

Missed out on 20 words or less by 6 words. I wonder how many sets of instructions that you could get to be 20 words or less regarding Land Rovers. Eg replacing air filter: undo canister, remove old, insert new, close canister - 8 words. Timing belt change would be a bit more difficult in 20 words or less.

[AndyG]

Silly me, i always assumed it was a raw egg and there was a degree of flex in the shell.

His sessions never made it to DVD did they ?

[Mick_Marsh]

Hard boiled egg with shell removed. It conformed to the milk bottle neck as it was drawn down by the vacuum created as the bottle cooled.
Ah. You fell into Prof. JSM's trap. Vacuums don't suck. It's the air pressure outside the bottle that push the egg in. That is the whole point of the demonstration.
Do you also remember how he demonstrated that with a 44 gallon drum? A more impressive demonstration.

[mike123]

Mick, you are right, it was about differences in pressure. I didn't see the 44 gallon drum experiment unfortunately. He was a very interesting character and made science interesting.

[Grappler]

This prompted me to watch a few episodes from the archives.

So many of his demonstrations didnt go to plan. Total fails! They didnt bother editing, he just blunders on. Still inspirational stuff however

[Didge]

Hah, our school dux (now working for Microsoft I believe) back in the day went on his show. He made some minor mistake and the Prof said to him, "Chell*% (I won't type his full name), you fool! which made the rest of us less than ordinary at the time. If the smartest guy in the school is considered a fool, then what for the rest? Still, a lot better than the attitude of the soft cocks we have in education admin these days.
