(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.

Europe 2022 - Part 2

 

 

 

In July and August 2022 Wendy and I travelled to Europe and to the United Kingdom (no longer in Europe - at least politically).

This, our first European trip since the Covid-19 pandemic, began in Berlin to visit my daughter Emily, her Partner Guido, and their children, Leander and Tilda, our grandchildren there.

Part 1 of this report touched on places in Germany then on a Baltic Cruise, landing in: Denmark, Finland, Estonia, Latvia, Sweden and the Netherlands. Read more...

Now, Part 2 takes place in northern France. Part 3, yet to come, takes place in England and Scotland.

Australia's Hydrogen Economy

 

 

  

As anyone who has followed my website knows, I'm not a fan of using 'Green Hydrogen' (created by the electrolysis of water - using electricity) to generate electricity. 

I've nothing against hydrogen. It's the most abundant element in the universe. And I'm very fond of water (hydrogen oxide or more pedantically: dihydrogen monoxide). It's just that there is seldom a sensible justification for wasting most of one's electrical energy by converting it to hydrogen and then back to electricity again. 

I've made the argument against the electrolysis (green) route several times since launching this website fifteen years ago; largely to deaf ears.

The exception made in the main article (linked below) is where a generator has a periodic large unusable surpluses in an environment unsuitable for batteries. In the past various solutions have been attempted like heat storage in molten salt. But where there is a plentiful fresh water supply, producing hydrogen for later electricity generation is another option.  Also see: How does electricity work? - Approaches to Electricity Storage

Two of these conditions apply in South Australia that frequently has excess electricity (see the proportion of non-hydro renewables chart below). The State Government, with unspecified encouragement from the Prime Minister and the Commonwealth, has offered A$593m to a private consortium to build a 200MW, 100t hydrogen storage at Whyalla.  Yet, the State already has some very large batteries, with which this facility is unlikely to be able to compete commercially.  Time will tell.

On Hume and Biblical Authority

 

 

2011 marks 300 years since the birth of the great David Hume.  He was perhaps the greatest philosopher ever to write in the English language and on these grounds the ABC recently devoted four programs of The Philosopher’s Zone to his life and work.  You will find several references to him if you search for his name on this website.
