The Irrawaddy (Ayeyarwady)

We left Bagan by boat heading for Mandalay.  It took 14 hours against the current. 

The travel guide had described the boat as 'nice'.  It was certainly preferable to 12 hours in a bus. It was possible to roam about and there was a sort of tea room on board with a free breakfast. But to call it 'nice' suggests a vessel that is ship-shape and well maintained.  That it was not.  The consolation was that it hadn't far to sink.

The river is monotonous, the only excitement being the really shallow spots where two crew members went forward and poled for the bottom, calling the depth, often less than two metres.  Commercial traffic consists of barges and low draft tugs and these are led by a small boat checking the depth ahead in the shallow reaches.  Several times our boat took advantage of this path finding.

 

On the boat: above:  two views of the morning coastline
below: seeking the bottom; and why is there a bowl of
dead vegetable-matter on the binnacle, good luck charm?

 

The river fisher-folk use quite sophisticated long symmetrical boats, built of planks with a distinctive stern and brow post. They are traditionally poled or paddled but, in this modern world, a proportion have been fitted with a small petrol motor on the stern with a long propeller shaft that drives them along quite quickly.

 

Riverside encampments and fishing boats

 

There were occasional riverside encampments for fishers but the true banks are way off in the distance. It was reminiscent of the Nile.

A highlight was the Pakokku Bridge, an enormously long (3.5 km) combined road and rail bridge that was opened with great fanfare in January 2012.  It has a nominal clearance of 16 metres but the maximum river height is clearly evident on the concrete pylons which, I guess, reduces the clearance to around eleven metres, still ample for most river traffic.  It’s a conventional riveted steel truss bridge that might have been built in the 1930’s. Riveting is very labour intensive. 

Conventional and labour intensive or not, it is obviously of considerable future economic significance as it provides one of the few modern crossings of this river. The Irrawaddy together with its tributaries historically defined Burma, as a distinct from the communities of the other great river systems, the Ganges and Mekong, separated by mountainous regions to the West, North and East.

The Greatest Aviation Mystery of All Time

 

 

The search for Malaysia Airlines Flight 370 was finally called off in the first week of June 2018.

The flight's disappearance on the morning of 8 March 2014 has been described as the greatest aviation mystery of all time, surpassing the disappearance of Amelia Earhart in 1937.  Whether or no it now holds that record, the fruitless four year search for the missing plane is certainly the most costly in aviation history and MH370 has already spawned more conspiracy theories than the assassination of JFK; the disappearance of Australian PM Harold Holt; and the death of the former Princess Diana of Wales; combined.

The Chemistry of Life

 

 

What everyone 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 as well as other elements like sodium, calcium, phosphorous and iron.  

Organic molecules can be very large indeed and come in all shapes and sizes. Like pieces in a jigsaw puzzle molecular shape is often important to an organic molecule's ability to bond to another to form elaborate and sometimes unique molecular structures.

All living things on Earth are comprised of cells and all cells are comprised of numerous molecular structures.
