Australian Radio Astronomy book link
For CosGrays who showed such interest in Dave Jauncey's recent video, and who (unlike specialists) may not have this (open-access) 2021 Springer book in their library, I have a link or two for you non-specialists. However, this is not a rehash, but is just a readable historical account of AU Radio Astronomy mainly 1945-1960 with a wealth of nice photos, including the famous CosGray Canberra resident! Further, the final section briefly runs over later Radio Astronomy developments. Springer links follow for pdf and epub versions:
https://link.springer.com/content/pdf/10.1007%2F978-3-319-91843-3.pdf
https://link.springer.com/download/epub/10.1007%2F978-3-319-91843-3.epub
or in case of problems search "Golden Years of Australian Astronomy" and goto the Springerlink.
Enjoy the nostalgia

Scientists awake - the old pest has another video
You must stop that omicronitis and see this spectacular video on the Tonga earthquake:

CosGrays need brain food after 2 years of "it"
Tired of hearing & reading about delta, omicron et al? Synchronization studies are worth your time:
and underneath some nice references on the subject to explore. o examination will be held (whew).
It reminded this old 'Gray about resonance, and the famous case of the Tacoma Narrows Bridge Collapse "Gallopin' Gertie" in 1940. You've probably seen the spectacular video of the bridge collapse, but a proper Engineering explanation is also worth your time:
Enjoy

PS Considering structural disasters reminds Physicists of the Arecibo Radio Telescope (final) collapse a year ago, and an Engineering perspective follows, but resonance was not an issue (spectacular drone footage):

Steven Weinberg obituary
Cozgrays
Just a brief bit of info especially as we don't meet face to face these days. I'm sure all are aware that Google (ugh) returns quite a few videos of the late Steven Weinberg, so I won't labour the point, and won't post on Leo-blog.
This particular video of a 2010 lecture for Google (ugh) is a long 71' and covers a wide field most of which should interest fellow old-timers re his book of essays "Lake Views" (refers Austin TX not my local lakes). If not interesting better call your GP for an appointment quickly!
Cheers

Well done Tone! Thanks for posting all those posts that I had lost.
ReplyDeleteGlad to see someone is much better organised than I am.
I will now take a full backup of the site - just in case
I have now changed the dates of the re-posts based on the dates you have given at the top of each. They are roughly in date order now
