 This e-mail from Zita is self explanatory.

Dear Lucky and Mahendra,                              04 12 2019

           We’ve been talking of measures to ‘save the planet’ recently on the Batch Blog. And when I came across something our batchmate Prof Sanath sent me I thought this link which came with it would be good to share with our batch mates. This article deals with the damage done to sea life and to the environment by man’s use of plastic bags and our present unsatisfactory methods of dealing with waste.




I feel that it is only by being ‘bombarded’ with such news repeatedly, that human beings will take this subject seriously and do their bit to help.
 Yours sincerely,
  Zita

Waste not, want not! Save the planet!


By Zita Perera Subasinghe

What is it with humans!! We are so productive that over the past few millennia we have conquered the land, sea, air and outer space. We have climbed the highest mountain, dived into the deepest sea. We have made discoveries which have made life easier, given enjoyment, helped the needy and healed the sick.
We have produced fine art of immense value; unravelled scientific principles which helped understand life and made inventions of great value. We have, in the last 70 years understood the principles behind computers (complex devices which make fast calculations, understand what is called cyberspace, and advanced in the science behind computers so much that it has crept into every nook and cranny of life and it dominates our world. But these make life enjoyable.

But man has been so busy in his quest for going forward that now he is threatened by his own success as the world and the environment we live in are retaliating and opposing man by showing its disapproval. What it means is ‘we’ve become our own enemy’. We are slowly poisoning our own environment, the air we breathe, the earth we stand on, the water we drink and the food we eat. We have managed to bring about a climate change detrimental to the world, to the life on it and in it. We are slowly killing the trees, contaminating the water, poisoning the air we breathe and killing fish and animals.

So where has man gone wrong? Is it all man’s fault or is it the natural outcome of evolution and advancement?  Even if we do not have satisfactory answers, we must say STOP! Think! Change what you do, reverse your cars into the garages and go back to a more primitive life if necessary, eat less meat and burn less of fossil fuels.

Turn your inventive power to run equipment by solar energy and produce less and less carbon in day to day activities.

Think of efforts made by governments, various treaties made over decades, further green technologies. Let’s start today. Save every drop of water, every smidgen of energy and follow examples of green activists.

Think of Greta Thunberg the 16-year-old climate activist. She crossed the Atlantic by a sail boat to go to the US to continue her climate activist work there.

I suggest that we each bring forward what each can offer this debate. We can have a simpler way of life on earth, save life in the sea, give our children, nephews, nieces and grandchildren a healthier planet to live on at least as good as we have enjoyed.

The End of Scarcity.



The End of Scarcity.

A thought provoking article by Zita Subasinghe Perera based on a BBC Radio 4 programme.1

The end of scarcity, want, poverty, shortfall, deficiency? I know the above pronouncement will catch the eye of any human being. But it’s exactly the meaning behind a talk on this subject by James Burke on 26-12-2017 on BBC Radio 4. I listened to the recorded version twice as I was fascinated by the idea and now I am sharing it with you as it is thought provoking and it is not too far-fetched. Well, let me get on with it. The idea is one we are familiar with: The present state of science, technology and the advancements during the past, nearly 150 years of industrial revolution, has provided us the means to live without ‘want’. The principle of Mr Burke’s thesis is that ‘necessity sparks, sets off and keeps in motion, Innovation’. So, the lack of ‘Want’ can spell the end of Innovation.

Happily, the first WW in the early 20th Century gave a spurt of energy to advancement in ‘Innovation’. The piston pump was replaced by the rotary pump, a Glasgow University repairman being credited with this. WW2 in the mid 20th century gave rise to the need for units like ‘ladies who calculated the angle at which a shot has to be fired to hit the enemy target’ and at that time they were called ‘computers’.

The first mechanical Computer
And now in the mid to late 20th century, the innovative geniuses produced the first ‘computer,’ a machine to handle the multiple calculations which were earlier done by the ladies of WW1.Mr Burke refersto this as ‘the intention to give humans a means to do complex activities in a very short time and expense.’

Big Data
The computer has the ability to hold big numbers- called Big Data which big companies use for ‘predictive analyses. Big Data leaves a footprint whenever and wherever we do something ‘online’ and companies use this to send us adverts and pressurise us to buy stuff. Big data uses our smart phones in our pockets to learn where we are and prompt us what to buy things and even the payment can be done instantaneously by connecting us to our bank accounts. It happens already in certain Big Stores the whole process being calledGrab and Go.

The Start of the end of Scarcity
In the 1950s they were able to predict that if we went on with ‘business as usual ‘and scarcity gradually ended we’ll face economic collapse by the end of the 21st century as the stimulus of Scarcity to bring about Innovation would not be there. Early to Mid 20th C saw the start of over population, industrialisation, starvation and resource depletion driven by our consumer life style. The international political reaction to this was putting the brakes on fossil fuels and cutting back on urban expansion and industrialisation, almost Apocalypse Now!

Making machines smaller the answer?
Fortunately, the innovative thinker in the form of Nobel Prize winner Richard Fyneman comes to the fore. He thought the answer is to make machines as small as possible. It turns out that it is possible to make each ‘bit’ (a piece of info) as small as one atom long. It took a while to get things moving but in 1987 two IBM ers invented the scanning, tunnelling microscope to make molecules. There are ‘gazillions of molecules everywhere, an inexhaustible resource’. Using this new device, one could put atoms and molecules together and you could produce anything you want even a cup of tea! These machines were in nanometres (the width of a hair is 80 nanometres.) This Nano processor is also called a moat a word derived from a ‘moat of dust’ as that is the size of this machine!

Nanoproducts and Nanotechnology
These products, called Nano-products, are already being made in about 2000 labs around the world! Nano particles are found in cosmetics, bacterial bandaging and wrinkle free, water-proof clothing. Using a Nano processor,one could ‘stick the end of a straw into dirty water and drink clean water at the other end’. Nano technology can be used to produce solar cells enabling the consumerisation of the 8 billion people of the earth in one giant economy therefore costing no fuel but just the energy of the sun in the solar cell. Many big Institutes around the world are working flat out to achieve this.

Replication
 Like in ‘Star Trek’ we are making the road map to Replication, i.e. to replicate anything. You can call this ‘merging computation and communication with fabrication to bring the programmability of the digital world over to our analogue world’. But remember, you are making what you CAN make and not what you NEED to make. And you can end up with a surplus.

Digitising designs and materials.
So, as told above, onecan digitise designs.
The next is to digitise materials using elements H, O, C, N and 20 amino acids. That is all you need. This is anyway what man has done in the past 4 billion years or so of evolution. Difference? Now it will be so much faster. These machines called moats do away with the need to cultivate the land and harvest or work in factories. It’s all there in a machine at atomic level giving you all you need. And all you need to do is talk to it. Yes, you actually ‘talk to it’. Science fiction? No! It’s Fact and it happens now!

End of Innovation and Isolation of man
The problem is that the End of Scarcity spells the End of Innovation, stand- still and isolation of man.  Family is not necessary, under this scheme. Socialisation? No! You can have your grandma and your pals and treat them to a slap-up dinner. You can tell your Moat and it will enable you to talk to them and they will come as 3D holograms so real that you forget they are not. You’ll never be lonely or bored.

Spending time with Nature
Want to visit the countryside? You can create it where you are, with all the features you want, a river, a farm, anything you like. All you do is tell your moat to do it. Sounds like winning the lottery? Well Yes and No! Read on and you will see the reason.

What’s awaiting mankind
You send a Nano factory to every city country and village and they make all the extra ones they need and make one available to every family, even every individual. There would be no need for money, or a job, no need for taxes, in fact, no need for governments as what they do is spend our tax money to maintain the infrastructure.

Education and Health?
Moats controlling the medical devices made at home can look after health. As for Education: education for what? In today’s world with robots taking over our jobs, and education is to make us creative, one can ask, creative for what purpose?

Culture
What about the culture we shared? Well, we’ll never again need to group together to survive.

Abundance
We know how to deal with scarcity, i.e. Innovate! But abundance? We have little experience of that. But all this will take no more than 50 years to hit us. Is all this a figment of the imagination? Well, even if some of it happens to be, surely, we ought to think about it?

The final outcome
In the popular joke, a man drops from the top of a sky scraper and as he is passing the 50th floor you ask him how he’s doing. And he says ‘So far so good!’ But you know ‘hitting the bottom’ is not far away!

-          The End!-
