Tiny commitments from a thousand homes – mind separating matter

Untitled-3

 

Some may be wondering after Meethotamulla where all the Colombo waste is going. However, I do have a feeling that most had no idea whatsoever where things were disappearing into until the pictures of Meethotamulla came through their wide screens.

Initial Court orders of a few days to Karadiyana and Dompe, etc. met with strong opposition and those directions are no more taken. It is not the mayors who have to face the popular music but the tractor drivers and sanitation workers.

The absence of a place to deposit would mean CEB lamp posts perhaps getting buried with bags filled with household waste which in turn would attract animals of varying sizes as one need not guess about the attraction of fast food outlets to the animal world. It is an interesting social mystery why lamp posts are preferred for this particular purpose.

Post-Meethotamulla we all discussed the importance of waste segregation and doing your bit at home whenever possible. Media outlets did allocate some prime time slots for getting this message across. Time invariably passes and Sri Lankans do demonstrate their unique ability to listen and forget!

While one may oppose the display of a picture depicting a dead body being pulled out of the pile of collapsed garbage and buildings at Meethotamulla, in a call for action to do your own bit first, our action or rather the reactions sadly led us to interpret that they unfortunately did die in vain! We as a society enable mistakes to happen and never fully react positively to a situation taking whatever the lesson from an event. How many such situations can we recall!?

Meethotamulla disaster’s life lessons

The Meethotamulla disaster had many life lessons – to those who believe in bagging garbage and simply forgetting the rest of the journey and associated impacts, to those who were warned of danger and saw the cracks appearing yet perhaps ignored the call perhaps in favour of more payments or the fatal attraction to secondary economic activities courtesy the dump, decision makers who had many a chance yet went on business as usual, etc.

A collection of bags from a thousand places when placed over a small plot of land over time can give rise to a mountain of garbage with the potential to kill and we have unfortunately witnessed just that. One should not think that a nominal payment of a property rate to the Pradeshiya Sabha or a municipal council is going to absolve one from the responsibility of a generator.

Some of these prevailing rates are really insignificant and actually not worth the effort of collection and issuing a receipt in my view. Yet with such payments we expect a service of such high excellence. It is simply inexcusable that we have allowed such a situation to exist up to now. With a figure of 0.8 kg of solid waste per person per day in urban areas, we appear to top the league table in the region for waste generation. Yet our knowledge and the commitment to be part of the solution are far from satisfactory.

Joining the greatest hunt in science – Sri Lanka with CERN


DFT-10-13

Sri Lanka’s Permanent Representative to the UN in Geneva Ambassador Ravinatha Aryasinha and the CERN Director General Rolf-Dieter Heurer sign an Expression of Interest Agreement to begin cooperation between CERN and the scientific community in Sri Lanka, on Thursday, 25 June 2015, at the CERN Headquarters in Geneva. CERN International Relations Head Dr. Rüdiger Voss, Sri Lanka Permanent Mission Deputy Permanent Representative Samantha Jayasuriya and Sri Lanka Permanent Mission Second Secretary Dilini Gunasekera were associated with the ceremony – File photo

The practice and the pursuit of science has witnessed many an attempt in pursuing grails of various kinds, with some holier than others. However, there has been one hunt which has been termed as the greatest hunt in science – the search for the Higgs boson!
Untitled-2
This piece of writing in addition relates to Sri Lanka’s late entry to the wonderful world of particle physics as physics may be taking a whole new turn since Higgs particle had been uncovered and Nobel’s awarded. Who says there is ever a dull moment in science?

Interestingly the pursuit for the particle – one among many but considered the most elusive of all – takes place below around the border between Switzerland and France. The Swiss-French landscape may not really reveal much on the surface other than its natural beauty Alps in the distance, etc., as they say the money coming from 20+ countries is spent underground and not for surface decor! The area houses the most sophisticated machines mankind has ever built. It is cooperation in science at its very best and in the not-too-distant future Sri Lanka too has hopes of playing a role of sort.

Body burden

The 21st century living is showing some interesting developments – have we being too creative and are about to pay the price for being so? Has our temporary applications taken permanent abode within us thus changing who we are? Time will tell but the results at present is indicating us to take note of and take real due care. The answer lies not in purging ourselves with the unwanted but more so with purging our heads from the imbalanced smartness that we appear to demonstrate.

We walk into a supermarket and avail ourselves many a product which contains a multitude of chemicals to realize some specific property. Sometimes we gladly embraced bottles filled with chemicals because the aroma that the spray gives to us is quite pleasing and titillate our senses and perhaps those who are around as well. Instead of getting rid of a negative smell we tend to mask the negative with a product purchased to give an acceptable perception.

With some analysis we may find that we actually spend more on these products than on our food. While the chemicals that we have introduced, synthesized and produced, in large numbers have resulted in some extensions to our average life span, have yielded a higher quality of life, there are indications that some of these developments may actually turn out to be not too wholesome after all.

Today we speak of having introduced more than one million chemicals and most are finding their way into commercial operations, services and products. Everyday many are coming across a wonder chemical. Check the price of a high end perfume and one may understand the power of a chemical ingredient in turning both heads and commerce around.

Lankan scientist makes major breakthrough in Physics

Sri Lankan young scientist Ranga Dias a postdoctoral fellow, Lyman Laboratory of Physics, Department of Physics, Harvard University has contributed to a major scientific breakthrough in Physics.

Isaac Silvera, Cabot professor of the natural sciences and Ranga Dias have produced metallic hydrogen, which has been just a theory for more than eight decades. Scientists have been working on metallic hydrogen for decades.According to Harvard Gazette, nearly a century after it was theorized, Harvard scientists report they have succeeded in creating the rarest material on the planet, which could eventually develop into one of its most valuable.

In their experiments, Silvera and Dias squeezed a tiny hydrogen sample at 495 gigapascal (GPa), or more than 71.7 million pounds per square inch, which is greater than the pressure at the center of the Earth. Professor of the Natural Sciences Isaac Silvera, who has been working on metallic hydrogen for 45 years, disclosed to Harvard Gazette that their work creates an important window into understanding the general properties of hydrogen, it also offers tantalizing hints at potentially revolutionary new materials. Sri Lankan scientist Ranaga Dias pointed out that a room temperature superconductor, could change our transportation system, making magnetic levitation of high-speed trains possible, as well as making electric cars more efficient and improving the performance of many electronic devices.

Ranga Dias , who born in Sri Lanka , did his undergraduate studies at University of Colombo , Faculty of Science and graduated in 2006. In 2007, he moved to Washington State University for graduate studies and he completed his Ph.D in the field of extreme condensed matter physics. – Mendaka Abeysekera in New York
