Dedicated to my students

My thanks to one of my past student who reminds me about some interesting views of books. But as I don't like to mention each and everyones concerned over a certain views so I considered it as the better way for collecting alltogether as roof of discussion. Yes,the taste of reading books over different topics, browsing the large public library or Institutional place is not going to be an idea of past and can't be replaced by this very new system of e-books and e-library as I am not sure how long we peoples will be able to sit in front of this system of reflection of lights in the form of dancing words which we all the time prefer to change the colour of the pages. Very recently when I was going through one of the book title"You are born to Blossom"by Dr.A.P.J.Abdul Kalam and my experience over there in this field of teaching young students;then I came to know that really a teenager can't adopt an adults character as a role model for them except their parents and teacher as their role model even though there is change in the system of society as well as environment. See if your young kids are following the paths of Albert Eisntein or Newton as their role model but bilogically it is out of continuation of life process of being a human. Here comes an idea of one of the speaker who was talking about the change of the trend in human behaviour which I strongly condemned and even I raised a question regarding that point. He was talking about humans time table time for taking rest and the difference in the natural day and night structure according to the modern life style,but my objection was that the very essence of the beginners ryme "Early to bed and Early to rise,makes a man healthy,wealthy and wise"should there all the time for our kids as it is natural neccessity. Yes,our system are failure as we the constituents of the system are failure and so if we need to change thesystem means a change starts from our own system and on the other hand our younger ones are the future of the next generation.

TRYST WITH DESTINY

'Awake to freedom' "Long years ago we made a tryst with destiny, and now the time comes when we shall redeem our pledge, not wholly or in full measure, but very substantially.At the stroke of midnight hour, when the world sleeps, India will awake to life and freedom. A moment comes which comes but rarely in history, when we step out from the old to the new, then an age ends, and when the soul of a nation, long suppressed, finds utterance. It is fitting that at this solemn moment we take the pledge of dedication to India and her people and to the still larger cause of humanity.At the dawn of history India started on her unending quest, and trackless centuries are filled with her striving and the grandeur of her successes and her failures. Through good and ill fortune alike she has never lost sight of that quest or forgotten the ideals which gave her strength. We end today a period of ill fortune and India discovers herself again.The achievement we celebrate today is but a step, an opening of opportunity, to the greater triumphs and achievements that await us. Are we brave enough and wise enough to grasp this opportunity and accept the challenge of the future?Freedom and power bring responsibility. That responsibility rests upon this assembly, a sovereign body representing the sovereign people of India. Before the birth of freedom we have endured all the pains of labour and our hearts are heavy with the memory of this sorrow. Some of those pains continue even now.Nevertheless, the past is over and it is the future that beckons to us now.That future is not one of ease or resting but of incessant striving so that we might fulfill the pledges we have so often taken and the one we shall take today. The service of India means the service of the millions who suffer. It means the ending of poverty and ignorance and disease and inequality of opportunity. The ambition of the greatest man of our generation has been to wipe every tear from every eye. That may be beyond us but so long as there are tears and suffering, so long our work will not be over.And so we have to labor and to work, and work hard, to give reality to our dreams. Those dreams are for India, but they are also for the world, for all the nations and peoples are too closely knit together today for any one of them to imagines that it can live apart. Peace has been said to be indivisible, so is freedom, so is prosperity now, and so also is disaster in this one world that can no longer be split into isolated fragments.To the people of India whose representatives we are, we make appeal to join us with faith and confidence in this great adventure. This is no time for petty and destructive criticism, no time for ill-will or blaming others. We have to build the noble mansion of free India where all her children may dwell."

-- Speech by Jawaharlal Nehru

(Jawaharlal Nehru, gave this speech as India's first Prime Minister to the Constituent Assembly in New Delhi at midnight on August 14, 1947. Though this speech is full of ideals and embellishments to inspire a nation, about to make a new beginning, it is historic and can be recognized as the first voice of Independent India.)

Collection from many corners of Science

MY VEIWS OVER THE RECENT ISSUE OF NAGAS IN NORTH EAST

Peoples should be unite as it makes the sense of unity.So regarding the ongoing issue of nagas in north eastern part of India for the formation of a greater Nagaland by integrating some naga inhabited lands of adjoining states like Manipur,Assam,Arunachal Pradesh. Naturally not even argumentive by taking any source of means which they are counting,it may be totally unjustice to have such an integration by differentiation of others. Above this the theory of claiming the place where you are as yours in this system of democary is totally falls eventhough there were historical evidences without considering any of communial or racial or religious matter. So as far as a citizen of this democratic nation not only as a resident of North East politically,I should suggest very fairly that as every community can have a convention or getogether for their wellbeing like we are going to have Tamil International conference in Coimbatore by the next month you peoples,we peoples and everyone can have a conference or convention or meeting in a better way. I do hope all the nagas will have an International conference in Nagaland for the development of Naga community by the next time and this will be an eye opener for everyone even those who are making laws in this country and those who are implimenting those laws also. So let's hope for preservation with new ideas not with differentiation.

EACH SECOND OF OUR EXISTENCE IS SO COUNTABLE

It is vivid truth that the very existence of the word countable seems to be started from the very essence of money which everyone needs in our life ever since we started our civilisation. But the very uncountable wprd "time" which nobody care about each day which we are passing without making a sense of its uses not for even hours or minutes or seconds. But don't you mind that the above two sentences are in reverse according to the law of nature. I meant time should be countable and money should be uncountable in reverse as we live with time not with money all the time. Once I was talking with a successful person by his acheivement,then he was letting down the importance of "time" for youths who are eager for success in their life. He said that we youths should have time all the time,it meant that if the work is to be done than we should have time for that but if the work is not capable or not that too much of importance to us than we should neglect immediately instead waiting for the answer yes from our mouth. And work should be planned already with time. So here i meant that let's pay attention or have a mind for each and every moment which we are living at here should be of countable. Like,have you ever counted in terms of days not in terms of minutes for your existence in your life. upto now? So just try it as makes you to increase the value of time.

HOPE AND MOBILE

Once a while after receiving some sms and as usual we everyone used to get it in our new mode of communication which shows nothing differentiation over race,caste,community,sex etc. in our society execpt the joke,emotional,lovey,congrates,good morning and goodnight,jobs are there,new informations so and so ,but really when i went through each and every sms which i got from my different fellows,for a while my mind stuck to somewhere about a change and a hope in our generation and the next comming generation. Really we have a lots of morally emotional sms which is forwarding thoughout,we have a lots of caring sms throughout,we are sometimes very close with this very short "HW R U?'."GUD NYT ". "TKCR". "HAVE GRT TIME"..even from one end of the world to the other end. So,this is the hope,this is the care,this is the concern,this is the corporation. But it may take some time to reach upto that goal we hope as it takes time to write some interesting thought over sms. A Change of behaviour,a change of language,a change of concer over each other,a change of even for our career that is what we can see on the merits of "MOBILE" other than this "walk while you talk"LOGO. So,your care is not to just forward the sms you got but atleast read it twice that makes a lot of sense. Everything is on you.

This is my SMS for you forever "Just keep a mind all the time wherever your are A GOD IS THERE WHO IS ALL THE TIME LOOKING AFTER A POSITIVE CHANGE IN YOU. Take care all the time. Have a nice time."

ALBERT EINSTEIN

"It is almost a miracle that modern teaching methods have not yet entirely strangled the
holy curiosity of inquiry; for what this delicate little plant needs more than anything,
besides stimulation, is freedom."
Einstein with his sister.
Einstein's family had moved to Italy to try to establish a business, and he joined
them for a glorious half year of freedom from work and anxiety. In 1895 he took
the entrance examination for the Swiss Federal Institute of Technology -- and he
failed. He was advised to study at a Swiss school in Aarau; here his teachers were
humane and his ideas were set free. His thoughts turned to the theory of
electromagnetism formulated by James Clerk Maxwell, seldom taught even in
universities at the turn of the century.

From a classroom essay Einstein wrote in French at the age of 16,
explaining why he would like to study theoretical mathematics or
physics: "Above all it is my individual disposition for abstract and
mathematical thought, my lack of imagination and practical talent. My
inclinations have also led me to this resolve. That is quite natural; one
always likes to do things for which one has talent. And then there is a
certain independence in the scientific profession which greatly pleases
me."

Einstein graduated from the Aarau school and entered the Institute of
Technology in Zurich. Around this time he recognized that physics was
his true subject. Only there could he "seek out the paths that led to the
depths." He also realized that he could never be an outstanding student.
Fortunately his friend Marcel Grossmann had the conventional traits
Einstein lacked. While Einstein worked in the library or the laboratory,
Grossmann took excellent notes at the mathematics lectures, and gladly
shared them with his friend before examinations. Einstein later wrote,
"I would rather not speculate on what would have become of me
without these notes."

Einstein grew familiar with the successes of past scientists who had tried to explain the world entirely through
atoms or fluids, interacting like parts of a machine. But he learned that Maxwell's theory of electricity and
magnetism was defying efforts to reduce it to mechanical processes. Through a new friend, the engineer
Michele Besso, Einstein came to the writings of Ernst Mach -- a skeptical critic of accepted ideas in physics.


"As a somewhat precocious young man, I was struck by the futility of the hopes and the
endeavors that most men chase restlessly throughout life. And I soon realized the cruelty of
that chase, which in those days was more carefully disguised with hypocrisy and glittering
words than it is today."

After Einstein graduated with an undistinguished record, he made a number of efforts to get a university job,
and failed. He found only occasional jobs on the periphery of the academic world. He felt he was a burden on
his none too prosperous family, and wondered if he had been mistaken in trying to become a physicist. Finally
he got a position at the Swiss Patent Office in Bern. It was "a kind of salvation," he said. The regular salary
and the stimulating work evaluating patent claims freed Einstein. He now had time to devote his thought to
the most basic problems of physics of his time, and began to publish scientific papers.


Einstein's closest friend, with whom he walked home from the Patent
Office every day, was Michele Besso. Einstein thought him "the best
sounding board in Europe" for scientific ideas. With other friends in
Bern, all unknown to the academic world, Einstein met regularly to read
and discuss books on science and philosophy. They called themselves the
Olympia Academy, mocking the official bodies that dominated science.
Einstein's began to attract respect with his published papers (described in
the next section), and in 1909 he was appointed associate professor at the
University of Zurich. He was also invited to present his theories before
the annual convention of German scientists. He met many people he had
known only through their writings, such as the physicist Max Planck of
Berlin. Soon Einstein was invited to the German University in Prague as
full professor. Here he met a visiting Austrian physicist, Paul Ehrenfest.
"Within a few hours we were true friends," Einstein recalled, "as though
our dreams and aspirations were made for each other.”


At the Zurich Polytechnic a romance had arisen between the handsome
and witty would-be science teacher and a young Serbian woman, Mileva
Maric, the only woman in Albert's physics class. Einstein's family
opposed any talk of marriage, even after Mileva gave birth to a daughter
(who was apparently given up for adoption). The pair finally married in
1903 after Einstein got his job at the Patent Office. Einstein discussed
physics with Mileva, but there is no solid evidence that she made any
significant contribution to his work. In 1904 a son was born, and a
second in 1910.


Through letters, visits, and science meetings, Einstein came to know
most of the major physicists of Europe (there were not many in those
days). In 1912 Einstein was invited back to the Swiss Federal Institute of
Technology as professor. Here he rejoined his old friend Marcel
Grossmann, now professor of mathematics. With Grossmann's aid,
Einstein studied the mathematical theories and techniques which he
found necessary for his work toward a new theory of gravitation.
Meanwhile, Einstein was being introduced to a different sort of world by
another friend, Friedrich Adler: the world of the Second International and
its attempt to halt the growth of international rivalries in Europe.

In 1914, the German government gave Einstein a senior research appointment in Berlin, along with a
membership in the prestigious Prussian Academy of Sciences. When Einstein had left his native land as a
youth, he had renounced German citizenship and all of the militarist German society. But Berlin -- with no
teaching duties and a galaxy of top scientists for colleagues -- could not be resisted. It was the highest level a
scientific career could ordinarily reach.
"With such fame, not much time remains for his wife," Mileva complained. "I am very starved for love."
Einstein felt suffocated in the increasingly strained and gloomy relationship. He found solace in a love affair
with his cousin, Elsa Löwenthal. Mileva and Albert separated in 1914, after bitter arguments, and divorced in
1919. That same year he married Elsa, and settled in with her and her two grown daughters by a previous
marriage. "The Lord has put into him so much that's beautiful, and I find him wonderful," Elsa later wrote,
"even though life at his side is enervating and difficult."


"A storm broke loose in my mind."

MARCH 1905


Einstein sent to the Annalen der Physik, the leading German physics journal, a
paper with a new understanding of the structure of light. He argued that light
can act as though it consists of discrete, independent particles of energy, in
some ways like the particles of a gas. A few years before, Max Planck's work
had contained the first suggestion of a discreteness in energy, but Einstein
went far beyond this. His revolutionary proposal seemed to contradict the
universally accepted theory that light consists of smoothly oscillating
electromagnetic waves. But Einstein showed that light quanta, as he called the
particles of energy, could help to explain phenomena being studied by
experimental physicists. For example, he made clear how light ejects
electrons from metals.

The Annalen der Physik received another paper from Einstein. The wellknown
kinetic energy theory explained heat as an effect of the ceaseless
agitated motion of atoms; Einstein proposed a way to put the theory to a
new and crucial experimental test. If tiny but visible particles were
suspended in a liquid, he said, the irregular bombardment by the liquid's
invisible atoms should cause the suspended particles to carry out a random
jittering dance. Just such a random dance of microscopic particles had long
since been observed by biologists (It was called "Brownian motion," an
unsolved mystery). Now Einstein had explained the motion in detail. He had
reinforced the kinetic theory, and he had created a powerful new tool for
studying the movement of atoms.

"When the Special Theory of Relativity began to germinate in me, I was visited by all sorts
of nervous conflicts... I used to go away for weeks in a state of confusion."


Einstein sent the Annalen der Physik a paper on electromagnetism and
motion. Since the time of Galileo and Newton, physicists had known that
laboratory measurements of mechanical processes could never show any
difference between an apparatus at rest and an apparatus moving at constant
speed in a straight line. Objects behave the same way on a uniformly moving
ship as on a ship at the dock; this is called the Principle of Relativity. But
according to the electromagnetic theory, developed by Maxwell and refined
by Lorentz, light should not obey this principle. Their electromagnetic theory
predicted that measurements on the velocity of light would show the effects of
motion. Yet no such effect had been detected in any of the ingenious and
delicate experiments that physicists had devised: the velocity of light did not
vary.

Einstein had long been convinced that the Principle of Relativity must apply
to all phenomena, mechanical or not. Now he found a way to show that this
principle was compatible with electromagnetic theory after all. As Einstein
later remarked, reconciling these seemingly incompatible ideas required
"only" a new and more careful consideration of the concept of time. His new
theory, later called the special theory of relativity, was based on a novel
analysis of space and time -- an analysis so clear and revealing that it can be
understood by beginning science students.

Einstein reported a remarkable consequence of his special theory of relativity:
if a body emits a certain amount of energy, then the mass of that body must
decrease by a proportionate amount. Meanwhile he wrote a friend, "The
relativity principle in connection with the Maxwell equations demands that
the mass is a direct measure for the energy contained in bodies; light transfers
mass... This thought is amusing and infectious, but I cannot possibly know
whether the good Lord does not laugh at it and has led me up the garden
path." Einstein and many others were soon convinced of its truth. The
relationship is expressed as an equation: E=mc2.
