On the 17th February 2020 Wendy and I set sail on Queen Elizabeth on a two week cruise up to Papua New Guinea, returning to Sydney on 2nd March.

After a stop in Brisbane on the way the ship headed north to Rabaul, returning by:
Kiriwina Island; Milne Bay (Alotau); the Conflict Islands; and Cairns in far north Queensland
Sydney to Rabaul is around four thousand kilometres
In Part1, in July 2023, Wendy and I travelled north from Los Angeles to Seattle, Washington, and then Vancouver, in Canada, from where we made our way east to Montreal.
In Part2, in August 2023, we flew from Montreal, Quebec, Canada, down to Miami, Florida, then Ubered to Fort Lauderdale, where we joined a western Caribbean cruise.
At the end of the cruise, we flew all the way back up to Boston.
From Boston we hired another car to drive, down the coast, to New York.
After New York we flew to Salt Lake City, Nevada, then on to Los Angeles, California, before returning to Sydney.
Introduction:
The other day, my regular interlocutors at our local shopping centre regaled me with a new question: "What is AI?" And that turned into a discussion about ChatGPT.
I had to confess that I'd never used it. So, I thought I would 'kill two birds with one stone' and ask ChatGPT, for material for an article for my website.
Since watching the movie Oppenheimer, reviewed elsewhere on this website, I've found myself, from time-to-time, musing about the development of the atomic bomb and it's profound impact on the modern world.
Nuclear energy has provided a backdrop to my entire life. The first "atomic bombs" were dropped on Japan the month before I was born. Thus, the potential of nuclear energy was first revealed in an horrendous demonstration of mankind's greatest power since the harnessing of fire.
Very soon the atomic reactors, that had been necessary to accumulate sufficient plutonium for the first bombs, were adapted to peaceful use. Yet, they forever carried the stigma of over a hundred thousand of innocent lives lost, many of them young children, at Hiroshima and Nagasaki.
The fear of world devastation followed, as the US and USSR faced-off with ever more powerful weapons of mass destruction.
The stigma and fear has been unfortunate, because, had we more enthusiastically embraced our new scientific knowledge and capabilities to harness this alternative to fire, the threat to the atmosphere now posed by an orgy of burning might have been mitigated.
Method:
So, for this article on the 'atomic bomb', I asked ChatGPT six questions about:
As ChatGPT takes around 20 seconds to write 1000 words and gives a remarkably different result each time, I asked it each question several times and chose selectively from the results.
This is what ChatGPT told me about 'the bomb':
Back in 2015 a number of friends and acquaintances told me that Climate Change is a myth.
Half a decade on and some still hold that view. So here I've republished a slightly longer version of the same article.
Obviously the doubters are talking about 'Anthropogenic Global Warming', not disclaiming actual changes to the climate. For those of us of a 'certain age' our own experience is sufficient to be quite sure of that the climate is continuously changing. During our lifetimes the climate has been anything but constant. Else what is drought and flood relief about? And the ski seasons have definitely been variable.
