Water: The Elixir of Life

I have written a book entitling 'Water: The Elixir of Life'. It contains total ten chapters. These chapters are so  interesting that one can know the latest updates of water. I have tried to explore some greater details about water.

Introduction: Describes the background of water and why water took birth in earth & so many interesting questions. I have also specified the chemical gift of cosmic projectile to earth how made the womb of life.

The Blue Planet: Describes about the abundances of water in earth material. Structure of water, density of water, Salinity, Phase transition and Heavy water.

Life in Water: Describes why water is the blood of life and why is it called the cosmic juice. Water geometry, physical property, Impact of water on DNA & Oparin-Haldane hypothesis also been discussed.

Water works: Describes the water land, desert, seawater and freshwater consumption. 

                                                           Water, water, everywhere,

                                                          And all the boards did shrink;

                                                         Water, water, everywhere,

                                                         Nor any drop to drink

Water, water everywhere: Describes the hydro-logic cycle, recycling the biogeochemical cycle. 

Nor any drop to drink: Describes how the drinking water being wasted by human manual and mechanical pollution.

Healthy water, healthy lives: Describes pH scale and impact of ionized water.

Regeneration: Describes the steps taken by Government to recycle polluted water into pure and usable water - reclaimed water.

India's water sector: Turbulent times ahead: Describes policy taken by Govt. of India and different states for water sanitation.

You can make a difference: Describes the problems with growing population, how to find new sources and redistribute water, reduce demand and recycle. 

Hundred Years of Superconductivity & its prospect

I have written a paper entitling Hundred years of Superconductivity and its prospect. It contains the detail history of superconductivity in last hundred years. It describes the discovery of supercunductivity, Meissner effect, Electrical & Magnetic properties of superconductor, London equation, Type-I and Type-II superconductor, Isotope effect, Electron-Phonon coupling, Electron-Electron interaction, Ginzburg-Landau theory, Cooper pairing, Nambu-Eliashberg theory and BCS theory. It pleasures me to write such article. Still I do believe it could be publish. I read so many Nobel lectures to write this paper.
 

Science learning in Non-formal Settings

This is a parallel approach of learning science beyond formal method of learning. School, College & University etc. is the way of formal education as well as learning. There is some specific syllabus, students have to take that syllabus - learn the subject - think about the subject, prepare for examination and after examination there is an evaluation process. But in case of Non-formal learning there is no syllabus, no examination even no evaluation. Besides there is no age limit. Here Museums play a vital role for the age from five to eighty.

Grechen Jennings [ Editor of "Exhibitionist", the journal NAME] & Karen Lee [ Numismatic Curator, Smithsonian National Museum of American History ] came from USA and assigned us visitor study at Science City, Kolkata. On 7th and 14th July 2012, ten MS people have divided into three groups and we had taken visitors feedback. We had modified Nano-lab, Spinning Chain & Pin-screen exhibits. I can conclude that we had enjoyed the session and our contribution to develop the exhibit was appreciable to visitors. The following video shows our activity at Science City, Kolkata.

Coins & Notes

The Dissertation topic has been declared for MS students. I have to explore socio-historical impact of coins and currencies in Indian Doctrine. Initially I have to write a synopsis. Then to go for main stream. This project will take place under Mr. Nataraj Dasgupta, Curator, Central Research & Training Laboratory, Kolkata. I may have to go for British Council, Indian Museums & National Library, Kolkata, to get necessary documents.

Before this, I have a hobby to collect foreign coins very long back. It was no longer continued due to several reasons. Till then, I have coins from Canada, USA, France, Britain, Netherlands and notes from Nepal & Bangladesh. The hobby has lost but the past hobby turned into a big Dissertation and this Dissertation made a huge responsibility.

Movie on Properties of light

In this third semester Prof. Ranjan Parekh (Jadavpur University) gave an assignment to make any movie containing fifteen minutes representation on Macromedia Flash 8. I've wrote a script on Properties of Light.

I've discussed here five properties of light. One can understand easily those properties. This is my first movie of my life. It is 7.33 minute long.

Time with John R. Wennersten

John R. Wennersten  is an historian-journalist currently living on Capitol Hill in Washington. He is Professor Emeritus of American History at the University of Maryland, Eastern Shore.

He has came Kolkata during July 2012. His recent book Global Thirst is taught here, in MS class. He wanted to capture a photograph with a copy in our group, I had forgotten to bring that copy, and set back behind Sir.   

Reincarnation & understanding

In our MS class the discussion was going over method of understanding in case of children. How they understand, what they interest first and how we can measure those and so on. Grechen Jennings, USA was teaching very interestingly those things. There are so many unknown things came out from by discussion and research.

I was thinking something new, that will make all of us more dynamic.
So I asked that : Madam, do You believe in reincarnation?
Grechen replied being a christian she does not believe in reincarnation.
Then I told her assuming that reincarnation occurs, then why each and every new born human baby should have to teach crawling, walking, swimming etc. 

As a result the class becomes dynamic and the answer could be found in http://museumcommons.blogspot.in/ [ blog of Grechen Jennings],

Time with Robert Freidel

Prof. Robert Friedel, Professor History of Technology & Science, University of Maryland, had came last year in N.C.S.M., Kolkata.

He spent one full month with our group. The adjacent figure shows Prof. R. Friedel with MS Science Communication 2011 which is the most successful batch ever entered. We have spent a nice time with SIR.

Time with Grechen Jennings and Karen Lee

It is my great pleasure to publish our recent activity in MS batch July 2012 at N.C.S.M. Kolkata. The adjacent is a group photo with Grechen Jennings [ fifth from left ]

Developmental Design of exhibit Tornado in NCSM, Kolkata

I have theoretically calculated the developmental design of Tornado exhibit in NCSM, Kolkata. There is a small exhibit called Tornado. It is a very well known exhibit all over India by NCSM,Kolkata. At the bottom, there is an arrangement of keeping water in contact with humidifier. This humidifier moisturizes water and a fan of fixed r.p.m. on the top creates rotation of that moisture.

By developing that exhibit I have introduced an equation of motion and came to the conclusion that if the entrance opening of the moisture be increased then it will be more prominent than it is.     

Successful Experimentation of R-B Convection cell

On Sep.2011, I've done a successful experiment on Rayleigh-Bernard Convection cell. It is very much well known that, when water or a liquid is heated a convection current circulates. This circulation is clearly visible in making tea - is a best example of convection cell. Now if  the wedge of liquid is thin, a number of convection cells appeared, rather the thick wedge only one cell appears. It was not been done before NCSM. This experiment has performed in CRTL, Kolkata only by me. I have take concern to Mr. Kua Patten, exploratorium and Tetsuro Ojio of N.C.S.M. Japan. You can visit the following webpage to see the exhibit on R-B Convection Cell: www.admin@ncsm.city.nagoya.jp.
