When we talked of going to Hawaii for a couple of weeks in February 2018 several of our friends enthusiastically recommended it. To many of them it's a nice place to go on holidays - a little further to go than Bali but with a nicer climate, better beaches and better shopping - with bargains to be had at the designer outlets.

To nearly one and a half million racially diverse Hawaiians it's home.

To other Americans it's the newest State, the only one thousands of miles from the North American Continent, and the one that's more exotic than Florida.

To some it's historically significant - the site of America's single greatest military defeat, unless you count Vietnam or perhaps Afghanistan - and it all took place on a single day: "a date which will live in infamy".

Here, on my father's 25th birthday, the course of world events took a dramatic new direction.  He was not yet married to my mother.  So to me it's one of those places where history most clearly influenced the conditions necessary for my birth and thus the birth of my children too. 

But why was the United States Pacific Fleet at Pearl Harbour on December 7 1941?  And why is that fleet no longer there?

That story goes back to the arrival of Captain James Cook at Kealakakua Bay, on the west coast of the island of Hawaii, on January 16 1779, and the outcomes that momentous event triggered for inhabitants of the newly discovered Sandwich Islands as more and more strangers arrived.

I found myself fascinated by the youngest US State's short but turbulent history. Statehood is one of the more recent events that I remember clearly.  But you might like to skip these sections if these and other improbable events leading to your birth are of no interest.

Balkans

 

 

In September 2019 we left Turkey by air, to continue our trip north along the Adriatic, in the Balkans, to Austria, with a brief side trip to Bratislava in Slovakia. 

'The Balkans' is a geo-political construct named after the Balkan Peninsula between the Adriatic and the Black Sea.

According to most geographers the 'Balkans' encompasses the modern countries of Albania; Bosnia and Herzegovina; Bulgaria; Croatia; Greece; Kosovo; Montenegro; North Macedonia; Serbia; and Slovenia. Some also include Romania.

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.

Discovery of the Higgs boson

 

 

Perhaps the most important physics discovery of my lifetime has finally been announced.  I say 'finally' as its existence has been predicted by the 'Standard Model' for a long time and I have already mentioned this possibility/probability in an earlier article on this website (link).

Its confirmation is important to everyone, not just to physicists working in the field of quantum mechanics.  Like the confirmation of the predictions of Einstein's Theory of Relativity we are now confronted with a new model of reality that has moved beyond an esoteric theory to the understanding that this is how the Universe actually is; at least as far as the Standard Model goes.
