How did find the electron

What is the electron?The atom is made by electrons,protons and neutrons.Philosopher assume there must be atom in element.it is the smallest part of the element.Also Philosopher have said that there is a another smallest part in atoms after J.J.thomson`s experiment of Cathode Ray.Thomson show that there was some of atoms.

mind can create your all dreams

We all have lot of future plans / dreams.But we have to hard work for get these aims.Human mind is the wonderful thing  in world.It can create anything what we want most.Some people do wonderful things using their mind.

      Load buddha is the best Human being who had developed the human mind better.Also jesus,Mohommed,.....like.

      If we can develop the our mind using meditation,Yoga ... We can do wonderful things in world.Also we don`t need a phone to call with some one because we can also talk with some one using mind.Also we can move big things using mind.Also we can know what is our future happening .

how did find the atom?

               All of student can`t learn well specially science like chemistry or physics or maths.Why?There is some problems in our learning way.We must not going to commit to memory when are we learning.We must understand what we learn.Then we can understand any difficult lesson easily.Also when we are going to learn chemistry we must understand what we learnt because chemistry is built by lot of assumptions.We can`t see atoms,molecular....like that.
              So we learn how did people find the atom?.How did people get some idea about a atom?.Now i`m going to tell you .How did people get some idea about a atom?

The Atom

           Atom /molecular is the smallest part of  a element.element are something like threes,animals, metals,soil,rocks like this.All things are made by Atoms or moleculars.In pure element are made by only one type of atom.Impure element are made by two or more type of atoms(molecular).
Consider a Copper bar

stability of a rectangular pontoon

Experiment :       Stability of a rectangular pontoon.

Aim              :  1. To compare the theoretical  and experimental values of the metacentric height.

                         2. To verify that the position of the metacentre is independent of the position of

                              the centre of gravity.  

                          For a rectangular pontoon floating in water.

Apparatus    :      Rectangular pontoon with a horizontally adjustable weight ( jockey weight ) , 

                             vertically adjustable weight, plumb bob and an angular scale

                              Scale , Knife edge , Water tank

Theory          :       Consider a rectangular pontoon of length i, width b , weight W , with a jockey 

                               weight w1 and a vertically adjustable weight w2 floting in water.

Marcet`s Boiler

Experiment : Marcet`s Boiler


Aim                     : To show the relation between the pressure and temperature of  
                                    satuated   steam             
                             
Theory            : At a given pressure, the  temperature at which a pure substance      
                                  changes its phase is called saturation temperature . Analogusly at 
                                  pure substance change its phase is called the saturation                      
                                  pressure.

How to learn to learn

Many student have very big problem that when they have to face some exam they will get a tension for for exam.Why we  get a extra tension to exam.

1. If we haven`t study enough we can get a tension to exam.
2. If we study well , but we can`t realize again and agian
3. Other thing is student have to get their parents` or some person`s purposes  

If we are not going to study well we can`t face to exam well.So we have to study well.If we can`t understand theory well we can ask it from friend or teacher again and again.If we do some thing again and again we can tough that work well.Think about this.When we are practice to drive a motor cycle we can`t drive it in first time.There is a rhythm in all things.If we can tough this rhythm we said that i learned.So we must learn to catch this  rhythm.Also maths,science have a rhythm.If some one catch this rhythm he/she will learn well.I`ll explain what is this rhythm.
