(UCLA History 2D Lectures 1 & 2)

 

Professor Courtenay Raia lectures on science and religion as historical phenomena that have evolved over time; starting in pre-history. She goes on to examine the pre-1700 mind-set when science encompassed elements of magic; how Western cosmologies became 'disenchanted'; and how magical traditions have been transformed into modern mysticisms.

The lectures raise a lot of interesting issues.  For example in Lecture 1, dealing with pre-history, it is convincingly argued that 'The Secret', promoted by Oprah, is not a secret at all, but is the natural primitive human belief position: that it is fundamentally an appeal to magic; the primitive 'default' position. 

But magic is suppressed by both religion and science.  So in our modern secular culture traditional magic has itself been transmogrified, magically transformed, into mysticism.

You may wish to start at Lecture 2 as this may give a better flavour of the issues discussed.  If either is of interest, the whole series is accessible from the YouTube link.

This series is strongly recommended despite its obvious technical shortcomings, only partly due to images being blurred or removed to avoid copyright infringement.

Each lecture lasts for over an hour so you may want to use the slider to hop ahead or back.   I found a good technique is to listen to the sound only while doing something else. You can easily stop and/or back up.

More Silk Road Adventures - The Caucasus

 

 

 

Having, in several trips, followed the Silk Road from Xian and Urumqi in China across Tajikistan and Uzbekistan our next visit had to be to the Caucuses.  So in May 2019 we purchased an organised tour to Azerbaijan, Georgia and Armenia from ExPat Explore.  If this is all that interests you you might want to skip straight to Azerbaijan.

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':

Australia's $20 billion Climate strategy

 

 

 

We can sum this up in a word:

Hydrogen

According to 'Scotty from Marketing', and his mate 'Twiggy' Forrest, hydrogen is the, newly discovered panacea, to all our environmental woes:
 

The Hon Scott Morrison MP - Prime Minister of Australia

"Australia is on the pathway to net zero. Our goal is to get there as soon as we possibly can, through technology that enables and transforms our industries, not taxes that eliminate them and the jobs and livelihoods they support and create, especially in our regions.

For Australia, it is not a question of if or even by when for net zero, but importantly how.

That is why we are investing in priority new technology solutions, through our Technology Investment Roadmap initiative.

We are investing around $20 billion to achieve ambitious goals that will bring the cost of clean hydrogen, green steel, energy storage and carbon capture to commercial parity. We expect this to leverage more than $80 billion in investment in the decade ahead.

In Australia our ambition is to produce the cheapest clean hydrogen in the world, at $2 per kilogram Australian.

Mr President, in the United States you have the Silicon Valley. Here in Australia we are creating our own ‘Hydrogen Valleys’. Where we will transform our transport industries, our mining and resource sectors, our manufacturing, our fuel and energy production.

In Australia our journey to net zero is being led by world class pioneering Australian companies like Fortescue, led by Dr Andrew Forrest..."
