Sir Isaac Newton was a great scientist.He had a little dog named Diamond.One day he went out of his room leaving his little dog asleep before the fire.For twenty years he was hard at work,studing a most difficult subject.On the table lays heap of papers on which he had put down the findings of his research for twenty years.When his master left the room ,and little Daimond,jumped on the table and overturned the lighted candle.The papers at once caught fire .Just when the paper had been completed burnt,Newton opened the door of the room.He saw that the fruits of his twenty years Labour’s had been turned into a heap of ashes.Three stood Diamond,the cause of his misichief.Almost any other man would have killed the dog on the spur of the moment .But Newton patted him on the head with kindness,although his heart was full of grief.Then he patiently set to work again.

MORAL:Patience is the strength of character.


A tea stall is a small shop where tea along with some dry foods in served.It is found beside the busy road and street,in the railway station,near an office,steamer at launch that and at a bus stand.It is also found in a village market and a cross-roaf.People sit there  to take light foods along with a cup of tea.There are few chairs and tables in a tea stall.Usually one or two small boys are employed to serve the customers with tea.The owner handles the coustomers from a corner of the stall.Coustomers are often heard shouting for more sugar.A big kettle is always kept on a hearth or a stove just to have boiling water.In a tea stall some people come to take a little rest taking a cup of tea.They are often found busy talk with unnecessary things.Sometimes the owner has to force them to leave the stall/seat.

Newton principia formulated the laws ofmotion and universal gravitation,which dominated scientist’s view of the physical universe for the next three centuries.By deriving kepler’s laws of planetary motion from his mathematical description of gravity,and then using the same principles to account for the trajectories of comets ,the tides,the precession of the equinoxes ,and other phenomena Newton removed the last doubts about the validity of the heliocentric model of the solar system.This work also demonstrated that the motion of objects on earth and of celestial bodies could be described by the same principles.His prediction that earth should be dshaped as an in oblate spheroid was later vindicated by the measurements of maupertuis , La condamine ,and others,which helped convince most continental European scintists of the superiority is Newtonian mechanics over the earlier system of Descartes.Newton built the first practical reflecting telescope and developed a theory of colur  based on the observation that a prism decomposes white light in to the many colours of the visible spectrm.He formulated an empirical law of cooling, studied the speed of sound,and introduced the nation of a Newtonian fulid.In addition to his work on calculas,as a mathematician Newton contributed to the study of power series,generalised the binomial theorem to non-integer exponents developed a method for approximating the roots of a function,and classified most of the civic plane curves.

Newton was a fellow of Trimty college and the second Luvasing professor of Mathematics at the university of Cambridge.He was a devout but unorthodox Christian and,unusually for a member of the Cambridge faculty of the day,he refused to take holy orders in the church of England,perhaps because he privately rejected the doctrine of the Trinty.Beyond his work on the mathematical scinces,Newton dedicated much of his time to the study of bibical chronology and alchemy,but most of his work in those areas remained unpublished until long after his death.In his later life,Newton became prensident of the Royal Socity.Newton served the British government as Warden and Master of the Royal mint.
