In June 2021 Wendy and I, with our friends Craig and Sonia (see: India; Taiwan; Japan; China; and several countries in South America)  flew to Ayer's Rock where we hired a car for a short tour of Central Australia: Uluru - Alice Springs - Kings Canyon - back to Uluru. Around fifteen hundred kilometres - with side trips to the West MacDonnell Ranges; and so on.

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.

On our return from Europe we spent a few days in Darwin and its surrounds.  We had a strong sense of re-engagement with Australia and found ourselves saying things like: 'isn't this nice'.

We were also able to catch up with some of our extended family. 

Julia's sister Anneke was there, working on the forthcoming Darwin Festival.  Wendy's cousin Gary and his partner Son live on an off-grid property, collecting their own water and solar electricity, about 120 km out of town. 

We went to the Mindl markets with Anneke and her friend Chris; and drove out to see Gary, in our hire-car, who showed us around Dundee Beach in his more robust vehicle. Son demonstrated her excellent cooking skills.

Hawaii

 

 

 

 

 

When we talked of going to Hawaii for a couple of weeks in February 2018 several of our friends enthusiastically recommended it. To many of them it's a nice place to go on holidays - a little further to go than Bali but with a nicer climate, better beaches and better shopping - with bargains to be had at the designer outlets.

 


Waikiki

 

To nearly one and a half million racially diverse Hawaiians it's home.

 

 


Downtown Hilo

 

To other Americans it's the newest State, the only one thousands of miles from the North American Continent, and the one that's more exotic than Florida.

The Atomic Bomb according to ChatGPT

 

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:

  1. The Manhattan Project; 
  2. Leo Szilard (the father of the nuclear chain reaction);
  3. Tube Alloys (the British bomb project);
  4. the Hanford site (plutonium production);
  5. uranium enrichment (diffusion and centrifugal); and
  6. the Soviet bomb project.

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':

The race for a SARS-CoV-2 vaccine

 

 

 

 

As we all now know (unless we've been living under a rock) the only way of defeating a pandemic is to achieve 'herd immunity' for the community at large; while strictly quarantining the most vulnerable.

Herd immunity can be achieved by most people in a community catching a virus and suffering the consequences or by vaccination.

It's over two centuries since Edward Jenner used cowpox to 'vaccinate' (from 'vacca' - Latin for cow) against smallpox. Since then medical science has been developing ways to pre-warn our immune systems of potentially harmful viruses using 'vaccines'.

In the last fifty years herd immunity has successfully been achieved against many viruses using vaccination and the race is on to achieve the same against SARS-CoV-2 (Covid-19).

Developing; manufacturing; and distributing a vaccine is at the leading edge of our scientific capabilities and knowledge and is a highly skilled; technologically advanced; and expensive undertaking. Yet the rewards are potentially great, when the economic and societal consequences of the current pandemic are dire and governments around the world are desperate for a solution. 

So elite researchers on every continent have joined the race with 51 vaccines now in clinical trials on humans and at least 75 in preclinical trials on animals.
