Rock Art

 

With its ample water diverse flora including edible plants and abundant wildlife this area has long been home to indigenous Australians.   It is probable that many of their tools and manufactures were made of wood or woven and did not survive for long in this climate but in some places rock art has survived for at least 2,000 years.  Aboriginal rock art can be found all around Australia but traditional lifestyle has been maintained in the Northern Territory for longer than anywhere else and the art retains its original significance; recording important events and handing down knowledge to the young; in addition to ritual.

In Kakadu some of this art has been made accessible to tourists.

The text says that: "in Northern Australia where art continues as part of the traditional lifestyle the young artist learns his clan designs from his close male relatives".

Men are the artists and keep the clan secrets.  

But some art is instructive; passing on local knowledge and rules for living:

 

Some is ancient and some quite recent.  It is quite usual to overwrite previous images; using the rock like a blackboard.

Europe 2022 - Part 1

 

 

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 touches on places in Germany then on a Baltic Cruise, landing in: Denmark, Finland, Estonia, Latvia, Sweden and the Netherlands. Part 2 takes place in northern France; and Part 3, to come later, in England and Scotland.

Fiction, Recollections & News

Alan Turing and The Imitation Game

 

The movie The Imitation Game is an imaginative drama about the struggles of a gay man in an unsympathetic world. 

It's very touching and left everyone in the cinema we saw it in reaching for the tissues; and me feeling very guilty about my schoolboy homophobia. 

Benedict Cumberbatch, who we had previously seen as the modernised Sherlock Holmes, plays Alan Turing in much the same way that he played Sherlock Holmes.  And as in that series The Imitation Game differs in many ways from the original story while borrowing many of the same names and places.

Far from detracting from the drama and pathos these 'tweaks' to the actual history are the very grist of the new story.  The problem for me in this case is that the original story is not a fiction by Conan Doyle.  This 'updated' version misrepresents a man of considerable historical standing while simultaneously failing to accurately represent his considerable achievements.

Carbon Capture and Storage (original)

(Carbon Sequestration)

At the present state of technological development in NSW we have few (perhaps no) alternatives to burning coal.  But there is a fundamental issue with the proposed underground sequestration of carbon dioxide (CO2) as a means of reducing the impact of coal burning on the atmosphere. This is the same issue that plagues the whole current energy debate.  It is the issue of scale. 

Disposal of liquid CO2: underground; below the seabed; in depleted oil or gas reservoirs; or in deep saline aquifers is technically possible and is already practiced in some oil fields to improve oil extraction.  But the scale required for meaningful sequestration of coal sourced carbon dioxide is an enormous engineering and environmental challenge of quite a different magnitude. 

It is one thing to land a man on the Moon; it is another to relocate the Great Pyramid (of Cheops) there.
