Travel 2024-25
> Mexico 2025
|
|
In March 2025 Wendy and I flew from Sydney to Los Angeles and caught a shuttle bus, south, to San Diego. After a couple of days in San Diego we joined an eleven day cruise to Mexico, aboard Holland America’s ‘Zaandam’. We first visited Mexico on our way to Cuba in 2012. I didn’t write about the Mexico or California components of our trip back then because I didn’t want to detract from the Cuba story.

> Bulgaria 2024
|
|
In May 2024 Wendy and I travelled to Europe. After around three weeks in Greece we spent a week in Bulgaria. On previous trips to Turkey and the Balkans we had bypassed Bulgaria, not knowing what to expect. My awareness was mainly informed by the spy novels that I've read in which Bulgaria figures. In my mind Bulgaria was most associated with the 1978 murder of Georgi Markov a Bulgarian writer who defected to the West to work as an anti-Soviet journalist for the BBC World Service and Radio Free Europe. While crossing Westminster Bridge in London one day he was stabbed in the leg by an umbrella-wielding Soviet agent. His assassination became known as the 'Umbrella Murder' and remains one of the most famous examples of Cold War espionage. So, I warned Wendy to watch for spies carrying umbrellas. But we soon discovered that that was all in the past and the stories of the country's general decrepitude were also highly exaggerated. We had, after all, just come by bus from Thessalonica in Greece (where 'shabby' has become an artform). |
> Greece and Türkiye 2024
|
|
In May 2024 Wendy and I travelled to Europe and after a string of flights landed in Berlin. From Berlin we flew to Greece and had an initial few days in Athens, before returning to Berlin, then back to Greece, a week later, to join a cruise of the Greek islands and Türkiye (just one port). At the end of the cruise we spent a self-guided week on Crete. We finished our European trip with a week in Bulgaria, followed by a week in the UK, before flying back to Sydney. Later in this trip we would visit the ruins of the Minoan civilisation that evolved and flourished for nearly two millennia, much earlier, between 3000 and 1100 BCE, when Athens was still a backward, neolithic stronghold. On Thera (Santorini) and Crete, The Minoan civilisation was perhaps the most advanced society the world had yet seen. Yet, after thousands of years, it crumbled. By the first millennium BCE most of Greece was ruled by the Mycenaeans who's civilisation fell into chaos in the 'Greek Dark Ages' before the advent of the 'Golden Age of Athens', from 480 to 404 BCE, when Athens produced some of the most influential and enduring cultural artifacts of the Western tradition. The playwrights Aeschylus, Sophocles and Euripides all lived and worked in 5th-century BC Athens, as did the historians Herodotus and Thucydides, the physician Hippocrates and the philosophers Plato and Socrates. Alas, the Golden Age of Athens lasted less than a long lifetime. Very soon, Phillip II of Macedonia, in the north, would employ improved military tactics to conquer most of Greece, in addition to: modern Albania; North Macedonia; most of Bulgaria; and a bit of Turkey (as far as the Bosporus). His son, Alexander the Great, would go on to defeat the great Persian Empire and then to conquer a good deal of the known world, all the way from Egypt to the eastern Mediterranean and Central Asia. Democracy gave way to autocracy. In due course Rome would conquer Greece and the Byzantine Empire (Eastern Roman Empire), centred in Constantinople, would persist for almost nine centuries during Late Antiquity and the Middle Ages, until, in 1453, falling to the Ottomans (Turks). Greek influence within the Byzantine Empire was enormous as Greek became the 'lingua franca' during the development and dissemination of Orthodox (Eastern) Christianity. The Ottoman Empire was similarly influenced. Muslim scholars rediscovered the Ancient Greek authors from the Golden Age, translating and studying their writings, creating a new 'Islamic Golden Age'. so that today much we have of Aristotle; and other Ancient Greeks has been retranslated from Arabic. The advances in knowledge made by Islamic scholars during the Middle Ages and their interactions with China, that brought gunpowder, paper and advances in medicine and mathematics to Muslim Europe led, in turn, to the demise of Medieval society and the scientific revolution. Without this history, none of our modern technology would exist, in its current form, and none of us alive today would have been born, to observe it. So we found it quite interesting. |
> Hong Kong to Singapore 2024
|
|
On February 16th 2024 Wendy and I set-forth on a 20 day trip, revisiting old haunts in SE Asia. From Hong Kong we made a brief side-trip to Shenzhen in China then embarked on a Cruise, sailing down the east coast, south, to Singapore where we spent a few days, before returning home: [Hong Kong; Ha Long Bay/Hanoi; Hoi An; Ho Chi Min City (Saigon); Bangkok; Ko Samui; Singapore] If you are contemplating a trip to any of these destinations, or an ocean-going cruise, you may find these experiences of interest. |

Biology - we can't escape it
> The Prospect of Eternal Life
|
|
When I first began to write about this subject, the idea that Hamlet’s apprehension concerning 'that undiscover'd country from whose bourn no traveller returns' was still current in today’s day and age seemed to me as bizarre as the fear of falling off the Earth should you sail too far to the west. Yet it has become apparent to me that some intelligent, educated, people still identify the prospect of eternal life, in either heaven or hell, as an important consideration when contemplating their own life and death. |
> Gaia
|
|
During our recent trip to Central Australia, I found myself wondering if there is more or less 'life' out here than there is in the more obviously verdant countryside to the north south east or west. Perhaps the entirety of the Earth's biota - James Lovelock's Gaia - is optimised by 'survival of the fittest' to fully exploit the prevailing conditions, so that, at any one time, the total mass of living cells the planet can support has been maximised? Then, maybe, given the present planetary environment, the total biological cake can't get any bigger - it can only swap one: individual; species; order; phylum; etc; for another? This is, of course, pure, unsubstantiated, speculation - born of my 'peripatetic musings'. What do you think? |

This article - that begins with 'What everyone should know' was written back in 2013 as an appendix to The Meaning of Life, my wide-ranging essay for my children about understanding: what we can know and what we think we do know. |
Energy and the Environment
> Australia's Hydrogen Economy
|
|
I've nothing against hydrogen. It's the most abundant element in the universe. And I'm very fond of hydrogen oxide (or more pedantically: dihydrogen monoxide), commonly known as water. I've made the argument against the electrolysis (green) route several times since launching this website fifteen years ago; largely to deaf ears. Now, at last, I feel a little vindicated. The principal prophet of 'Green Hydrogen' has been Australia's richest man, billionaire, Andrew (Twiggy) Forrest, former CEO of Fortescue Metals Group. On September 25th, just in time for my birthday, Fortescue rejected their commercially problematic hydrogen option and placed a US$2.8bn order for electric mining equipment and vehicles, including 360 battery-electric trucks, from Liebherr.

With world media attention no longer on the Covid Pandemic the spotlight has moved on to the war in the Ukraine, and at least in Australia and the UK, to the rocketing cost of electricity.
> Electricity Woes
|
|
The Federal Government, that came to power on a promise to substantially cut power bills, has had to concede, that instead, there have been substantial price increases.
During the election campaign the Shadow Minister for Climate Change and Energy repeatedly asserted that the solution lay in increased wind and solar generated electricity, that he asserted were now cheaper than fossil-fuel generated electricity. Meanwhile, in July 2022, Wendy and I had occasion to visit the town of Rønne on the small Danish island of Bornholm. There on the quayside were a dozen huge wind-turbine nacelles. As I had some spare time on my hands, I looked on-line and discovered that they were Vestas V174-9.5 MW units for installation off the coast of Germany, for either the Baltic Eagle or Arcadis Ost 1 project. I compared the published project cost with other large energy projects around the world. Suffice it to say, that wind-generated electricity is not price-competitive with modern fossil-generated electricity - it's just a lot cleaner. The assertion that wind is less expensive to install than contemporary nuclear generation (per unit of deliverable energy) is also open to question. Huge wind farms are certainly more environmentally impactful and less aesthetically pleasing than a relatively inobtrusive nuclear plant. |

Seeing this film got me thinking about nuclear power again.
On this website, there are numerous references to the potential benefits of this discovery, that was confirmed by the first atom bomb in the year I was born, and has formed a background to my entire life, both as the gift of new knowledge and as an ever-present threat. That new knowledge has saved and/or extended my life on at least two occasions, while at the same time, radically transforming the society in which we all live. And if you have a spare three hours, the movie, that is now being streamed on YouTube and Foxtel, is perhaps the best of last year's offerings.

> Electric Cars again-and-again
|
|
Electric vehicles like: trams; trains; and electric: cars; vans; and busses; all assist in achieving better air quality in our cities. Yet, to the extent that the energy they consume is derived from our oldest energy source, fire: the potential toxic emissions and greenhouse gasses simply enter the atmosphere somewhere else.
So are they actually more environmentally friendly than conventional, petroleum-fuelled, vehicles, when substantially powered by coal, oil and gas? |
> Climate Change - a Myth?
|
|
Several friends and acquaintances of my generation continue to assert that the climate is beyond our control or that 'Climate Change' is a myth. A friend who is sceptical about sea level rise, recently asserted that I was wrong when I claimed, that as a result of flooding during king tides, I had observed sea level change of six inches to a foot during a lifetime of ferry trips on Sydney Harbour. So I checked. Between 1914 and 2007 sea levels at Fort Dension in Sydney Harbour rose by between 0.73 - 1.13 mm/yr. That means that during my lifetime the average sea level in Sydney Harbour has risen by 51 - 79mm (2 to 3 inches). So my friend was both right and wrong. He's right in that it's not possible that I have correctly remembered water levels well enough to distinguish a median rise of 65mm in a tidal range of 2.1 m. Yet he is wrong in suggesting that there has been no sea level rise in Sydney Harbour AAP FactCheck. Might I be mistaken in other ways? |
Miscellaneous
> The McKie Family
|
|
This is the story of the McKie family down a path through the gardens of the past that led to where I'm standing now. Other paths converged and merged as the McKies met and wed and bred. During that time Newcastle grew from a small port town into one of the World's most important and innovative cities. Thus, they contributed to the prosperity, fertility and skill of that blossoming town during the century and a half when the garden there was at its most fecund. |
> Alternative Facts and other Untrue Tales

Most fiction has its roots in real events. Yet the flights of fancy (untruths) these inspire can be more fun. Some of these tales can be read in a few minutes others like: The Cloud and The Craft, require a good bit longer.

ChatGPT
Long ago, in my essay to my children: 'The Meaning of Life' I suggested that: "...if we ever make computers (or computer programs) that evolve without our aid, memes may find computers a better medium for their future survival and evolution. That would threaten our existence or make us the unwitting slaves of technology". In addition, my novella: 'The Cloud' and its prequel 'The Craft' both posit an intelligent cloud. Now several of my friends have asked me what I know about ChatGPT. I've had to confess that I'd never tried it. So, recently, I decided to rectify this.
> Testing ChatGPT
|
|
As January 26th approached I decided not to repost my usual, unchanging, comments on the date and instead ask ChatGPT about the date. This is what it told me: Australia Day according to ChatGPT I have now seen Oppenheimer - the movie twice (see the review below). So I gave ChatGPT the task of explaining the background to the Manhattan Project and the development of the Atomic Bomb. This is what it told me: The Atomic Bomb according to ChatGPT Updating a broken link to the popular song of the period: How 'ya gonna keep 'em down on the farm after they've see Paree? in my article : Love in the time of Coronavirus, I'd made the point that it was the American 'Dough Boys' who introduced the Spanish Flue to the trenches of WW1, where it became the most deadly modern pandemic, killing up to 50 million when the troops returned to their homes. By comparison: Covid19 has killed 7 million (to date) while world population has grown four-and-a-quarter times. This relative success is entirely due to effective vaccines. So, I asked ChatGPT to tell me about the song. This was what it told me: How 'ya gonna keep 'em down on the farm? But how would it go writing fiction? Well judge, or try it, for yourself Here... It takes less than half-a-minute to write a thousand words or more. By default it writes stories in the third-person around characters and/or places and/or circumstances that you supply in your request. To that extent, it is quite predictable but it gets much more interesting when you ask for a story in the first-person. Then it has to come up with a character's motivation. In the context of a future, self-aware, World Wide Web trying to imagine what motivates humans (or machines?), I found this quite disturbing. For I am Margery, a modern-day witch, and I will stop at nothing to achieve my goals. With my familiars by my side, I will carve out my place in this world, bending reality to my will and ruling over all who dare to defy me. And woe betide anyone who stands in my way, for they will feel the full force of my wrath. But for now, I bide my time, weaving my spells and ensnaring my prey, until the day comes when I will emerge from the shadows and claim my rightful place as queen of all I survey. And on that day, the world will tremble at the sound of my name, and they will know that Margery, the modern-day witch, reigns supreme. |
