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. 

 

 

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.

Malta

 

 

Almost everyone in Australia knows someone who hailed directly from Malta or is the child of Maltese parents. There are about a quarter as many Maltese Australians as there are Maltese Maltese so it is an interesting place to visit; where almost every cab driver or waiter announces that he or she has relatives in Sydney or Melbourne.

To Catch a Thief

(or the case of the missing bra)

 

 

 

It's the summer of 2010; the warm nights are heavy with the scent of star jasmine; sleeping bodies glisten with perspiration; draped, as modestly requires, under a thin white sheet.  A light breeze provides intermittent comfort as it wafts fitfully through the open front door. 

Yet we lie unperturbed.   To enter the premises a nocturnal visitor bent on larceny, or perhaps an opportunistic dalliance, must wend their way past our parked cars and evade a motion detecting flood-light on the veranda before confronting locked, barred doors securing the front and rear entrances to the house.

Yet things are going missing. Not watches or wallets; laptops or phones; but clothes:  "Did you put both my socks in the wash?"  "Where's my black and white striped shirt?" "I seem to be missing several pairs of underpants!"

Energy Solutions

 

Most informed commentators agree that Australia needs a better mix of energy sources.  We are too dependent on fossil fuel.  This results in a very high rate of carbon dioxide production per capita; and this has international and domestic implications in the context of concerns about climate change.
