CosGrays - Remembrance of Times Past
With a salute to Marcel Proust for the title. We oldtimers don't much think about fallout these days, but this is the subject of an interesting 13' video. Actually, it was the title "How Kodak Exposed The Atomic Bomb" which caught my attention, and Kodak itself is now mainly of historical interest. Is there a connection to CosGrays? Yes, it's on particles and physics, and some of us slaved developing cloud chamber films! Better catch it before the Big Tech Google censors decide what historical info is appropriate:
However, there's a catch on which you may be examined - listen carefully and find the howler at the start of the video.
Enjoy

Remember - back to Classical Mechanics
Absolutely fascinating video for Physicists. Watch carefully as the wing nut flips over.
The video is self-explanatory. There will be no examination on the topic - what a relief. It’s just Classical Mechanics, and I’m giving the “plot” away, just a consequence of the different moments of inertia on the three principal axes. The Russians tried to “hide” it! The tennis racquet trick jogged my memory – I did that with my old wooden "Pancho Gonzales" tennis racquet – I can actually remember that! Sadly I didn't stop to analyze. For those interested it's apparently only explained in the great textbook by the Russians Landau and Lifshitz on Classical Mechanics (they wrote a series of Physics books – Lev Landau is one of the greats of course). I have an extract available to any old masochists (via Academia.edu):

A Blast From The Past - For The Historical Record
While converting my archives to landfill, I came across a couple of vintage audio files, which were tape recorded from ABC Sydney radio 2FC. These have been digitized to elementary dual mono mp3 audio files for transmission to the blog and playable on any device. The file details and links follow.

Posted for possible interest of KosmicGGGrrrayers seeking an amusing nostalgic trip. Those around at the times will especially "appreciate" the changes over that strange decade. You need a full 45 minutes, and patience will be rewarded with a real "trip".
Enjoy

Addendum to Joe's Story - comment re Tom Playle
Thanks to Andy for those wonderful memories. It jogged my memories about Joe's mate Tom Playle. Tom and I shared at least one of those sojourns to Narrabri to tend SUGAR. Tom told me he was a London Bobby during WW2 and he married a nice Jewish girl (local Brit or refugee?). They had two daughters, and Tom hinted that they would be open to dating penniless physics students. That reminds of the countless hours spent lab demonstrating, first year lectures, tutorials, and exam paper marking for peanuts - a form of slavery. The postgrad CommSchol ended after 3 years. It didn't exactly inflate my bank balance for a home loan! Well, that jogged another memory of Tom. He indicated to me that someone was looking for an electronics wiz to "work on" the poker machines for the then huge South Sydney Juniors League Club - Tom was a member. I recall the Daily Mirror during its glory days in the late sixties writing about the activities of "colourful identities" who couldn't be named such as Mr Sin, Mr Big etc and who were connected to poker machines and other "activities". No way, Jose! I don't have a "therapist" so these are not "recovered" memories like recent events in the US. However, can someone amend and add to Tom Playle's bio?
