What you should know

Most of us already know: that an atom is the smallest division of matter that can take part in a chemical reaction; that a molecule is a structure of two or more atoms; and that life on Earth is based on organic molecules: defined as those molecules that contain carbon, often in combination with hydrogen, oxygen and nitrogen, and may include other elements like sodium, calcium, phosphorous and iron.  

Organic molecules can be extremely large.  Familiar extremely large organic molecules include plastics like polyethylene and many proteins, like spider web.

Chromosomes are structures within the cells of animals and plants consisting of very large molecules of  DNA (Deoxyribonucleic acid).   DNA stores and replicates information. It encodes the genes used by all complex living organisms on Earth to reproduce and function. 

The exception is viruses that use RNA to replicate by hijacking a host cell's DNA.  The ability of DNA to accurately replicate allows living organisms to divide and thus pass on life to their successors down the generations. 

Cell replication is what we call 'life'.  The replicating DNA molecule can therefore be regarded as the 'engine of life' or the 'life force' on Earth.  So it is quite a good thing to understand. 

It's amazing to think that we have only understood it within my lifetime, so throw away all those ancient texts.

Travel

The United Kingdom

 

 

 

On the surface London seems quite like Australia.  Walking about the streets; buying meals; travelling on public transport; staying in hotels; watching TV; going to a play; visiting friends; shopping; going to the movies in London seems mundane compared to travel to most other countries.  Signs are in English; most people speak a version of our language, depending on their region of origin. Electricity is the same and we drive on the same side or the street.  

But look as you might, nowhere in Australia is really like London.

Chapter 1 - Caught short

 

 

 

 

Christmas 2069 approaches and in the midst of the greatest retail spending frenzy for decades Bianca has been trying on clothes..  They're at Bergeroff Goodman, an up-market store. Bianca has been brought here by Margery who frequents such expensive places.  Unlike many other retail establishments in the world at this time of year, the store is not over-packed with shoppers.

Elsewhere many customers will expend their entire available credit and have even accumulated credit from earlier in the year to allow for this annual celebratory splurge.  Much of it will be expended on personal services, personal wellbeing, exercise, entertainment and of course religious practice and many will exchange gifts of credit towards these services with friends and loved ones.  But this store is very up-market and discrete.

This Monday lunchtime Margery is encouraging Bianca to buy a top quality black wool and mohair suit with a knee length skirt, similar to the one Margery is wearing.  Bianca had been resisting and equivocating when the call of nature gratuitously cut short their struggle.  The older woman had assumed Bianca's resistance was for financial reasons, insisting that a good suit is not an extravagance but an investment in Bianca's future.

A new political dawn

 

 

The State election on 26th March saw a crushing political defeat for the Australian Labor Party in New South Wales. Both sides of politics are still coming to terms with the magnitude of this change.  On the Labor side internal recriminations seem to have spread beyond NSW.  The Coalition now seem to have an assured eight and probably twelve years, or more, to carry out their agenda.

On April 3, following the advice of the Executive Council, the Lieutenant-Governor of New South Wales, gave effect to an Order to restructure the NSW Public Service. Read more...

It remains to be seen how the restructured agencies will go about the business of rebuilding the State.
