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

Romania

 

 

In October 2016 we flew from southern England to Romania.

Romania is a big country by European standards and not one to see by public transport if time is limited.  So to travel beyond Bucharest we hired a car and drove northwest to Brașov and on to Sighisiora, before looping southwest to Sibiu (European capital of culture 2007) and southeast through the Transylvanian Alps to Curtea de Arges on our way back to Bucharest. 

Driving in Romania was interesting.  There are some quite good motorways once out of the suburbs of Bucharest, where traffic lights are interminable trams rumble noisily, trolley-busses stop and start and progress can be slow.  In the countryside road surfaces are variable and the roads mostly narrow. This does not slow the locals who seem to ignore speed limits making it necessary to keep up to avoid holding up traffic.

His life in a can

A Short Story

 

 

"She’s put out a beer for me!   That’s so thoughtful!"  He feels shamed, just when he was thinking she takes him for granted.

He’s been slaving away out here all morning in the sweltering heat, cutting-back this enormous bloody bougainvillea that she keeps nagging him about.  It’s green waste tomorrow and he’s taken the day off, from the monotony of his daily commute to a job that he has long since mastered, to get this done.  

He’s bleeding where the thorns have torn at his shirtless torso.  His sweat makes pink runnels in the grey dust that is thick on his office pale skin.  The scratches sting as the salty rivulets reach them and he’s not sure that he hasn’t had too much sun.  He knows he’ll be sore in the office tomorrow.

Opinions and Philosophy

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.
