Chartres is famed for the 13 century: Cathédrale Notre-Dame.

Europe22 N France29

This Gothic cathedral, completed in 1220, features 2 towering spires, flying buttresses, and elaborate rose windows. In its day it was the second largest Christian church in the world, after Hagia Sophia in Constantinople, and was among the most popular destinations for Western Christian pilgrimage during the medieval period.

It's nearly one-and-a-half times larger, and considerably more ornate, than its, now rather charred, namesake in Paris.

The stations of the cross are particularly elaborate

Obviously, the town is even older than the cathedral, yet there are few remnants of the medieval. It's mostly far more modern, with a plethora of church related infrastructure (convents, hospitals and so on) radiating out from the centre.

Bali

 

 

 

 

 

At the end of February 2016 Wendy and I took a package deal to visit Bali.  These days almost everyone knows that Bali is a smallish island off the east tip of Java in the Southern Indonesian archipelago, just south of the equator.  Longitudinally it's just to the west of Perth, not a huge distance from Darwin.  The whole Island chain is highly actively volcanic with regular eruptions that quite frequently disrupt air traffic. Bali is well watered, volcanic, fertile and very warm year round, with seasons defined by the amount of rain.

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':

We all die of something.

After 70 it's less likely to be as a result of risky behaviour or suicide and more likely to be heart disease followed by a stroke or cancer. Unfortunately as we age, like a horse in a race coming up from behind, dementia begins to take a larger toll and pulmonary disease sees off many of the remainder. Heart failure is probably the least troublesome choice, if you had one, or suicide.

In 2020 COVID-19 has become a significant killer overseas but in Australia less than a thousand died and the risk from influenza, pneumonia and lower respiratory conditions had also fallen as there was less respiratory infection due to pandemic precautions and increased influenza immunisation. So overall, in Australia in 2020, deaths were below the annual norm.  Yet 2021 will bring a new story and we've already had a new COVID-19 hotspot closing borders again right before Christmas*.

So what will kill me?

Some years back, in October 2016, at the age of 71, my aorta began to show it's age and I dropped into the repair shop where a new heart valve - a pericardial bio-prosthesis - was fitted. See The Meaning of Death elsewhere on this website. This has reduced my chances of heart failure so now I need to fear cancer; and later, dementia.  

More fun and games.
