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.

Travel

USA - middle bits

 

 

 

 

 

In September and October 2017 Wendy and I took another trip to the United States where we wanted to see some of the 'middle bits'.  Travel notes from earlier visits to the East coast and West Coast can also be found on this website.

For over six weeks we travelled through a dozen states and stayed for a night or more in 20 different cities, towns or locations. This involved six domestic flights for the longer legs; five car hires and many thousands of miles of driving on America's excellent National Highways and in between on many not so excellent local roads and streets.

We had decided to start in Chicago and 'head on down south' to New Orleans via: Tennessee; Georgia; Louisiana; and South Carolina. From there we would head west to: Texas; New Mexico; Arizona; Utah and Nevada; then to Los Angeles and home.  That's only a dozen states - so there are still lots of 'middle bits' left to be seen.

During the trip, disaster, in the form of three hurricanes and a mass shooting, seemed to precede us by a couple of days.

The United States is a fascinating country that has so much history, culture and language in common with us that it's extremely accessible. So these notes have turned out to be long and could easily have been much longer.

Bonfire (Cracker) Night

 

 

We children were almost overcome with excitement.  There had been months of preparation.  Tree lopping and hedge trimmings had been saved; old newspapers and magazines stacked into fruit boxes; a couple of old tyres had been kept; and the long dangerously spiky lower fronds from the palm trees were neatly stacked; all in preparation.
