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!

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.

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

Look, my streetlights are on!

I remember late Arthur C. Clarke used to write to the press quite often when we had power shortages – and there were many such instances I must say, indicating lit streetlights in Colombo in the middle of the day even in times of power shortages. Perhaps late Arthur gave up the exercise as either the newspapers were not being read by those who had the power and the ability or we were believing streetlights anyway do not consume much power and a few being lit at all times is not exactly a crime against humanity.

He was asking for solar systems, more control with the ability to switch off when not needed, etc. However, we can continue to see the situation in some places. Yes the technology has been improved with solar streetlight systems having entered into use. There are many streetlights still managed by households which are by the side of a road and there is some deprivation of revenue to the CEB in that process. What is still evident is we are yet to master this service provision of running the streetlight system economically while serving the community when and where it is needed.  –

Nara Chandrababu Naidu

It was a refreshing and an impressive presentation that the Chief Minister of Andhra Pradesh – Nara Chandrababu Naidu – gave when he was in Sri Lanka on 8 January as the Guest of Honour on invitation of the President of Sri Lanka at the third year inauguration event of his ascendancy to presidency. The President had invited the Chief Minister to attend the celebrations of ‘Dawn of three years of sustainability of Sri Lanka’.

His speech had so many points to ponder and perhaps was a demonstration of someone who is in charge and with the perfect understanding of the situation – a sign of a politician in true command. The comparisons, SWOT analysis, and plans underway along with details clearly indicated a person with a mission. The speech was of more substance than rhetoric, of achievements than promises. Of course he is not new to the position with a solid history of performance in AP.

පිළිකා පියවි සෛල නසන්න සිරිමාවෝ සිසුවියකගෙන් ස්වාභාවික ඖෂධයක්

ජාතික විද්‍යා පදනමේ විද්‍යා හා පර්යේෂණ තරග සඳහා පාසලෙන් ඉදිරිපත් වූ සමාෂි, වර්තමානයේ ඉතා දරුණු ලෙස පැතිරී යන පිළිකා රෝගයට ප්‍රතිරෝධී වන අතුරුආබාධ නොමැති ස්වාභාවික ඖෂධයක් නිපදවීමට සමත්වූවාය. ජාතික විද්‍යා පදනමට යොමුකළ පර්යේෂණ යෝජනාවෙන් තේරී පත්වූ ඇය පර්යේෂණය සිදුකිරීම සඳහා කොළඹ විශ්වවිද්‍යාලයේ ජෛව රසායන අනුක ජෛවවේද හා ජෛව තාක්ෂණ ආයතනයේ ආචාර්ය සමීර ආර්. සමරකෝන් මහතාගේ පූර්ණ මගපෙන්වීම යටතේ පර්යේෂණය සිදුකළාය.
