Travelling is relaxation, Photography is Interest. I want to be a Man of Values rather than a Man of Success! I always have faith on this universe, on myself, that all the good things will happen to me.
Most difficult times are my greatest teachers, as they taught me several lessons! I want to make my life big; want to be wealthy, healthy, popular beyond limit. I enjoyed every small gift! I touched millions hearts! I did my part to make the world better place! Journey started from Majhergram Junior Basic School at my native village, there built my base very strong to be a good human being.
Studied there from Class V to X High School, one of the renowned institutions of West Bengal. I have completed B. Final Step was completing M. Though I am staying out of my home sinceI come from a village named Majhergram, near Gushkara in Burdwan District.
I am the only child of my parents, who are both teachers. So showing the way in blood! I belong to a joint family. Both of my Uncles are Engineer and Aunts are Home maker. I have lost my grandfather in who was a Teacher, is the Icon of my life.
All of them are my mentors and trendsetters of my life. It becomes a great fun when we meet each other after a long time as we are scattered in three different places. I am really lucky to born in my family. As from my childhood, I have been staying at different places, I have got the opportunity to meet some wonderful people. They are the soul of my life. After that, I have spent another fantastic 3years of mess life at Chandannagar.
Thereafter, during my professional journeyI am meeting lots of amazing people, some of them has become my friend. Thanks a lot for spending some of your valuable times by visiting my website.

Archan S Majumdar.Mathematics is more than the dry textbook exercises students at various levels in India, beginning from school, are made to solve. What is missing in high school and college curricula is the excitement of mathematical research.
Students, and the public, interested in mathematics, who wish to read something other than jargon-filled academic material, have nowhere to turn to. The precise identity that one gets. Since Brahmagupta is arguably the first mathematician to investigate this important equation in a general framework, the equation is nowadays called the Brahmagupta—Pell equation.

The Stranger at the Palazzo d'Oro. Oct 24, AM. But water will wear away rock, which is rigid and cannot yield.
As a rule, whatever is fluid, soft, and yielding will overcome whatever is rigid and hard. This is another paradox: what is soft is strong. Arriving at the top of the stairs, she grabbed the handle and tried desperately to open each of the three giant doors. The library's closed, lady. But the woman didn't seem to care. She seized one of the heavy ring-shaped handles, heaved it backward, and let it fall with a loud crash against the door.
Then she did it again. And again. Wow, the homeless man thought, she must really need a book. You're a passive observer and it is all moving by you boringly in a frame. On a cycle the frame is gone. You're completely in contact with it all.Students from various Government and private schools, colleges and general public visited the Institute during the day. Some of the Schools and colleges that visited the Institute included Govt. A variety of science demonstrations that explain basic science were conceptualized and executed by the PhD students and staff of the Institute.
Members from all the four groups of the Institute as well as the facilities including library, mechanical engineering services and electronics engineering group were seen enthusiastically demonstrating experiments and interacting with the visitors. A peek into the experiments is given below. A sugar solution with a concentration gradient was used to bend light and motivate questions on refraction and the role of refractive index of a medium.
Two different types of pin hole camera were built and used for creating images. Part of a glass rod that was immersed into a solution in a beaker magically disappeared; turns out this was due to the fact that the refractive indices of the rod and the liquid were similar. The Astronomy and Astrophysics group used the simple concept of parallax to demonstrate a technique for measuring distances to many stars we see in the night sky Another attraction in the Astronomy and Astrophysics stall was models of various telescopes used in Radio, X-ray and Optical astronomy.
The theoretical physics group demonstration included inclined plane experiments where varying speeds of objects rolling down an inclined plane was used to explain fundamental science concepts. There were also demonstrations on sending and receiving signals from the EEG group as well as live demonstration of component fabrication by the Mechanical Engineering services.
During their time at the Institute the visitors also had the opportunity to interact with RRI PhD students and faculty regarding exciting science and technology initiatives and current research activities of the various labs of the Institute.
Viscosity of many dense suspensions rapidly increases under an applied stress, a phenomenon which is known as discontinuous shear-thickening or DST. Sometimes, these suspensions can even transform into a solid-like jammed state under very high stress known as shear-jamming SJ states. This reversible and almost instantaneous control of suspension viscosity by an external force can have wide range of future applications.
Few recent studies distinguish between DST and SJ states based on transient response measurements or using a secondary probe. Sayantan Majumdar and his students Subhransu Dhar and Sebanti Chottopadhyay of the Soft Condensed Matter group at Raman Research Institute, an autonomous Institute funded by Department of Science and Technology DST have proposed a novel and direct method for such distinction entirely based on steady-state measurement and without the need of a secondary probe.
Sayantan Majumdar is funded through the Ramanujan Fellowship. The research may help designing flexible, impact resistant, protective gears using dense suspensions for injury prevention in sports and security applications.
Their method is based on conventional rheology measurements, a branch of physics that deals with the deformation and flow of matter, especially the non-Newtonian flow of liquids and the plastic flow of solids.The detection of trapped atomic and molecular ions of rubidium, by extraction, from our thin-wire electrode-modified spherical Paul trap, is discussed in detail.
The compact geometry poses serious challenges and constraints for efficient extraction and reliable detection of ions. The solution to the dual challenge of counting the trapped ions with minimum pileup loss as well as detection that permits reliable mass spectroscopy is experimentally implemented.
The details of the ion extraction process are understood by numerical simulation. The experimental and numerical data are compared and found to be in close agreement. The reliability of the technique for future, multi-species experiments, is established, and possible improvements are discussed.

But what actually happens inside the material being cooled? How much heat can we remove from a material? Can we reach temperatures almost equal to absolute zero i. We know that all matter is made up of large number of atoms which are in a state of incessant back and forth motion. This energy due to motion, or kinetic energy, is perceived as temperature. Cooling any material essentially means reducing the kinetic energy of the atoms in the material.
When a system is sufficiently cold, the kinetic energy is negligible. In this case, the potential energy, which in dilute gases of atoms is very small, starts to determine interaction among the atoms, and so plays a major role in deciding the properties of the material.
As this happens, very basic quantum properties which would otherwise be masked at higher temperatures reveal themselves. Cooling systems to such regimes is therefore of critical importance for many physics experiments, and often the biggest challenge to overcome. As the atoms and ions in the gaseous phase tend to fly apart, even when very cold, chances of studying their interaction is greatly reduced.
Usually, trapping is done using a combination of electric, magnetic and light fields. In the RRI experiments, this led to two, co-centred globes of trapped ions and atoms, millimetres in extent, suspended in very high vacuum at the centre of a steel experimental chamber with many windows. Over the course of multiple collisions, the ion loses most of its kinetic energy. However, both of these processes require multiple collisions since each collision only removes a fraction of the kinetic energy from the ion.
In contrast, in this new cooling method based on RCE, almost the entire kinetic energy of the ion is removed in a single collision between a colliding ion and the parent atom. This results in an ion that is almost at rest.8f35 transmission
The mechanism works in homo-nuclear ion-atom systems i. The swap cooling technique is found to be more efficient than other conventional methods, since a single collision produces a cold ion. Under similar experimental conditions, the per-collision cooling via RCE mechanism was found to be about times higher than cooling via elastic collisions.
Experiments across the world are attempting to study ultracold collisions for the combined ion-atom system which has so far been elusive. According to the authors, this study underlines the importance of RCE as a mechanism in ion-atom systems and is an instrumental mechanism for ion-atom experiments in the ultracold regime.
