"The Big Bang-A Creator"

The Big Bang Theory is a theory which explains the orgin of universe and its consequences.It tells us an interesting story on how the explotions which took place 13.3 to 13.9 billion years ago,created evething in the universe.
According to the theory, universe initially consisted of dense cloud like matters which resulted in an explotion when they collided each other.It gradually cooled as it expanded and is still continuing to do so.It is bilieved that, at a point it will stop expanding and begin to contract to the form as it was 13.9 billion years ago.At a point in its expantion, the whole stars in the universe will die out and black holes become more common finally leaving the universe at a temperature of absolute zero known as big freez.Eventually the dark holes will evaporate and the universe will become so disorganised that it will be impossible for any kind of energy to be extracted, a point called heat death.Well after all these studies one thing is for sure: the big bang (if it really occured) is the orginator of everything we know and everything we are.

"Theory of Relativity- An Introduction"

The theory of relativity by Albert Einstien includes the two main theories: special and genaral relativity.It explains the structure of space time.Special relativity theory is based on two postulates:

1. The laws of physics are same for all observers in uniform motion relative to one another.


2. Speed of light is same for all observers regardless of their motion or the motion of ligt source.

General relativity is a theory of gravitationdevelopment of general relativity began with the equivalence principle in which the states of accelarated motion and being at rest in a field are physically identical.Some of the outputs of general relativity are:

1. Time goes slower in higher gravitational fields.


2. Orbits precess in a way unexpected in Newton's theory of gravity.


3. Rays of light bend in the presence of a gravitational field


4. A rotating mass drags along the space time around it.


5. The universe is expanding and the far parts of it are moving away from us faster than the speed of light.

A few more Blog topics for students of Class XI B for First Term Project

 Delight !! You have more options

As per the response received from students, String Theory is of a little bit higher level and the understandable components and content available is limited. Therefore it has been decided to include a few more topics so that students can post a blog on the topic of their choice.

1. Special Theory of Relativity
2. General Theory of Relativity
3. Superconductivity
4. LHC - Large Hadron Collider
5. Big Bang Theory
6. String Theory and GUT

The blogs must be posted on or before 15 July 2010 midnight. A student can add any number of posts. i.e, instead of waiting for the entire project to be completed, he/she can post the draft. You will be able to edit your own entries any time you want. The evaluation will be done from midnight of 15 July 2010 onwards.

The grades obtained will not be published on the blog, but it will be entered into your Progress Report against first term project.

Please keep the following points in mind while submitting your project

• The content should not be a copy-paste version of articles or information posted anywhere on the net. Read as many as you can and post what you understood in your own words
• Include photos, videos etc related to the project topic, but the source must be declared and due credit must be given to the author. If you are interested in using some copyrighted material, seek permission from the person holding copyright (You can request via email, usually available at the site which displays the copyright information)
• The entry can also be a fiction /story based on any one or more of the topics mentioned above.
• Give special attention in formatting your articles properly. Use bold for highlighting important points.
• Give suitable heading for paragraphs.
• Give a short overview of the entry as the first paragraph.

All the Best

|String|---|Theory|

The String Theory is a recent trend or theory is physics which is attempting to formulate a theory to harmonize quantum mechanics and general relativity.It is trying to prove that electrons and quarks in the nucleus are not zero-dimensional,but rather uni-dimensional oscillating lines called strings.It is said to possess only length and no other dimension.

This is one of the hottest research going on in the modern day physics.It has originated from the dual-resonance model which was proposed by Gabriele Veneziano in 1969.There are 5 major developed string theories.Each of them differs in the number of dimensions in which the strings developed and their characteristics.All these theories seems to be correct though.

Once scientists believed there were 5 superstring theories-Type I,types IIA and IIB and the two heterotic string theories.The thinking was that out of these five candidate theories, only one was the actual correct Theory of Everything.But now it is known that it was naive thinking and that each theory is connected.

"STRING" "THEORY"

String theory, also known by names such as "superstring theory" and sometimes "M-theory", is an idea that has been around for a rather long time, over two decades.

The discovery of string theory as a potential unified theory was something of an accident. In a context unrelated to the unification of forces, researchers in the 1970's wondered what theory one might be able to write down to describe a fundamental quantum string -- an object with a finite spatial extent, which could not be described in terms of deeper constituents. It was certainly an interesting new mathematical problem in a physical context.

Such a string would be described classically by giving the location of an object extended like a (straight or curved) line in space at a given time. The string could be closed, like a loop, or open, with two end points

"Teacher" in Quotes

Definitions

“A Teacher is the image of Brahma” -- Manu

“The teacher is a Brahma, the creator, he is God Vishnu, he is God Maheshwar.  He is entire universe, salutations to him.”  -- Indian Prayer

“The true teacher is he who can immediately come down to the level of the student, transfer his soul to the student’s soul and see through and understand through his mind.  Such a teacher can really teach and none else” -- Swami Vivekanand

“The teacher’s place in society is of vital importance.  He acts as the pivot for the transmission of intellectual traditions and technical skills from generation to generation and helps to keep the lamp of civilization burning” -- Dr. S. Radhakrishnan

“A teacher can never truly teach unless he is still learning himself.  A lamp can never light another lamp unless it continues to burn its own flame.  The teacher who has come to the end of his subject, who has no living trafic with his knowledge, but merely repeats his lessons to his students can only load their minds.  He can not quicken them” -- Tagore

“Every teacher and educationist of experience knows that even the best curriculum and the most perfect syllabus remains dead unless quickened in to life by the right method of teaching and the right kind of teachers.” -- Secondary Education Commission

“The Teacher is the real maker of history.” -- H.G. Wells

“The teacher is the maker of man.” -- Sir John Adams

Random Reflections

Random Reflections

Each and Every knowledge from time immemorial is registered in our brain. We know everything. But the sad fact is that we do not know that we know everything
Someone has to help us reveal the blanket with which the knowledge already in our subconscious mind is covered. This is the role of a teacher.
Now the educational system recommended in India has actually taken this idea to be granted. CBSE says, "Teachers need not teach  things, but tell the students what to learn and how to learn. Let the students learn themselves. The teacher has the role of a mentor and a facilitator. "

Formative Assessment:
CBSE Says

"Formative assessment is a tool used by the teacher to continuously monitor student progress in a  non-threatening and supportive environment. If used effectively it can improve student performance tremendously while raising the self esteem of the child and reducing the work load of the teacher. Some of the main features of Formative assessment are that it is diagnostic and remedial, provides effective feedback to students, allows for the active involvement of students in their own learning, enables teachers to adjust teaching to take account of the results of assessment and recognizes the profound influence that assessment has on the motivation and self-esteem of students, both of which are crucial influences in learning."

Humour - Don't Copy if you can't PASTE.

Received via email 

 A popular motivational speaker was entertaining his Audience. He Said: The best years of my life were spent in the arms of a woman who wasn't my wife!

The audience was in silence and shock. The speaker added: And that woman was my mother!

Laughter and Applause!!!

A week later, a top manager trained by the Motivational speaker tried to crack this very effective joke At home. He was a bit foggy after a drink. He said loudly to His wife who was preparing dinner, The greatest years of my life were spent in the arms of a woman who was not my Wife!

The wife went; ahhhh! with shock and rage.
Standing there for 20 seconds trying to recall the second Half of the joke, the manager finally blurted out and I can't remember who she was!

By the time the manager regained his consciousness, he was on a hospital bed.

Moral of the story

Don't Copy if you can't PASTE.

The importance of using simple language

Dear students (and visitors),

While you write your articles here, remember that it can be viewed by anyone from any part of the world via the web. He may be from any academic or financial or cultural background. If you want to convey your idea well, it must be comprehensible even by a layman.

So, it is always a good idea to call your friend, brother, sister or mom to have a look at what you have written when you preview it before submitting for publication.

Find below some suggestions to blog well,

1. Give a gist of what to expect from your article immediately after the title. (Be sure to make it as accurate as possible so as to avoid misguiding the visitors) The surfers are in a hurry to find what they want. SO let them know what they will get by reading the article in the first paragraph itself. They can choose to read the rest or leave based on the content overview you have provided.
2. Use paragraphs to separate ideas/ concepts. Do not put all your ideas on one page. Limit one idea or concept per paragraph.
   
3. Make sure the first line of each paragraph conveys the idea of that paragraph and then you explain the idea with narrations, illustrations, links etc.
4. Keep sentences short and avoid using uncommon words. If you use words whose meaning is known to all, try to add an explanation in parenthesis.
5. Use sub headings which describes the title of each paragraph further.
6. Use Bold to highlight important words.
7. If you give a link, explain what the link contains. Nowadays everyone fears clicking on links. So, it is necessary to briefly narrate the link - the name of the site and a brief overview of the site or web page.

All the best. Blog on to Rock the world.

Guidelines on writing for web based project

• Remember that what you are writing is going to be viewed by many (- sometimes millions)
• So you have the responsibility to check the accuracy of what you post before posting it on blog.
• Include bibliography so that the source of information is revealed. It is also useful for the visitors who want to read the subject matter further.
• The web is an active medium - Properly decorate and highlight points wherever necessary to lay proper emphasis to points.
• Never copy - paste content from other websites. However, you may assimilate the content represent in your own language.
  
• Make sure content is easy to read
• Create Effective Headings
• Provide links and connections wherever necessary
• Edit your submission again and again until the desired quality is reached.
