First Century of the Season!!

Just a quick update!! Last Saturday (29th July, 2006) while playing a Saturday League Cricket Match in Morrants Four Counties League against Winsolw Team, I scored my first century of the season. I scored 121, and finally got out in the 43th over while trying to hit a six on a long-on boundtry to push the score. It was really an amazing feeling to hit first century which also helped my team (Open University Cricket Club: http://openuni.play-cricket.com/home/home.asp) to score 261.

A visit to Sir Isaac Newton's birthplace!!!


















--------------------------
"Nature and Nature's laws lay hid at night: God said, Let Newton be! and all was light"

- Alexander Pope
------------------------

Last Sunday I visited none other than Sir Isaac Newton's birthplae, which is at Woolsthorpe Manor near Grantham. Newton lived in this house during the early period of his life before he went to study at the Cambridge University.

But the Woolsthorpe Manor holds more profound value in history because during the outbreak of the Great Pleague of London, 1665-1666, Newton was forced to return to Woolsthorpe Manor. And during this period Newton invented Gravity, Calculus and Optics.
------------------------

Some background of Woolsthorpe Manor:

The house is built in small plain limestone, nad it was Newton's grandfather who had taken possession of Woolsthorpe Manor in 1623 and Isaac was born premature and sickly on Christmas Day in 1642. Isaac's father, a prosperous Lincolnshire farmer, had had died two months before his son's birth. His mother went on to raise a second family nearby but Isaac remained at Woolsthorpe and spent an introverted and isolated childhood in the care of his grandmothers.

Woolsthorpe, with its simple T-shaped plan and mullioned windows, is a typical early-17th century manor house. The house, suitable for a well-to-do gentleman farmer of James I's reign, was built on the site of an earlier building sometime after 1623. The plain rooms have been furnished by the National Trust to reflect the lifestyle of a prosperous yeoman family. On some plaster walls of the passages and rooms mathematical diagrams and other figures may be identified. These may well have been scratched by Newton who as a boy was known to use any surface within reach.

The most important feature of the house is that as you go on the first floor of the house there are rooms on the either side of the staircase. The left hand room is a bedroom where Newton was born and they have preserved the old bed. The right hand room is more significant because this was Newton's study during the period of 1665-1666. And they have still preserved the first telescope made by Newton, the prism he used to do work on Optics, and also equally importantly, there is a show case where they have a third edition of "Principia Mathematica", which is Newton's major work on Differential Calculus.

Also in front of the house there is an apple orchard, and which still has the gnarled apple tree underneath which according to a legend Newton when he was in a contemplative mood struck with the Law of Gravity.
---------------------------

Newton's 1st Law:

"An object at rest remains at rest and an object in motion continues with a constant velocity in a straight line unless an external force is applied to either object."

Newton's 2nd Law:

"The acceleration of an object is directly proportional to the net force acting on it, while being inversely proportional to its mass."

Newton's 3rd Law:

"For every action there is an equal and opposite reaction."

Second Law of thermodynamics!!!

The law that forces the entire Universe to comply with its formulation!!!! The second law of thermodynamics is "the supreme law" of all the laws that were ever invented by a human being...

If someone is looking for the immortal place in the history of the mankind, try and answer the following question: "What it is the nature of physical foundation (or universe) in terms of the Second Law of Thermodynamics?"

Few interesting quotes by two giants:

"The law that entropy always increases -- the second law of thermodynamics -- holds I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much worse for Maxwell equations. If it is found to be contradicted by observation - well these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of Thermodynamics, I can give you no hope; there is nothing for it but to collapse in deepest humiliation. "

Sir Arthur Stanley Eddington, in The Nature of the Physical World. Maxmillan, New York, 1948, p. 74


"[A law] is more impressive the greater the simplicity of its premises, the more different are the kinds of things it relates, and the more extended its range of applicability. Therefore, the deep impression which classical thermodynamics made on me. It is the only physical theory of universal content, which I am convinced, that within the framework of applicability of its basic concepts will never be overthrown. "

Albert Einstein, quoted in M.J. Klein, Thermodynamics in Einstein's Universe, in Science, 157 (1967), p. 509.
----------------------------
There are many many different equivalent ways of stating the Second Law of Thermodynamics. Here is one of them:

The total entropy of an isolated physical system "never" decreases.

The total negentropy of an isolated physical system "never" increases.

Congradulations to Anil Kumble for completing 500 Wickets Landmark!!!




















Anil Kumble of India completed one of the most remarkable feat in the International Cricket Arena by completing 500 wickets landmark when he trapped Steve Harmison of England Leg Before Wicket. And he is the only Indian Bowler to complete such a feat. In his illustrious 16 years old carrier Kumble has grounded firmly in the International Cricket as a leg-spinner who although is not a big turner of a ball maintained his wicket taking ability by keeping accurate line and length.

Moreover Kumble has completed his 500 wickets landmark by taking 32 five wickets haul as well.

Truely very very special achievement and we are really proud of you Anil. Keep it going and your next target is to get 600 wickets....

They Played "Blood Holi", At The Feet of God!!!

(


A minute of silence for those who died at the bomb blast took place on 7th March, 2006 in Sankat Mochan Temple in Varanasi, India.



)
-------------------------
They once again managed to tear the peace process after rocking the holy city of Varanasi, where two high explosive bomb blasts took place killing INNOCENT 14 people and injuring 100 people. Till no one has claimed the responsibility of this hideous act, where few lives disappeared in history because they decided to visit the place where their maximum belief was insured.

What reaction one can give over such acts, when the lives lost, left others with the shattered memories and a road full of darkness and tears!!!

As an Indian and a humble human being simply like to think:

"The more you try, the more resilient we become to survive in this dark hour and to rescue humanity out of pandemonium"

New Pharaonic Tomb Discovered!!!!

Archaeologists have discovered an intact tomb in the Valley of Kings. This tomb is the first one to be discovered after 1922's monumental discovery of King Tutankhamun's tomb which was lead by Howard Carter....

The Valley of the Kings near Luxor in southern Egypt was used for burials for around 500 years from 1540BC onwards.

The tomb, the 63rd discovered since the valley was first mapped in the 18th century, was unexpectedly found only 5m away from King Tutankhamun's, a member of the team told the BBC's World Tonight.

A team led by the University of Memphis found the previously unknown tomb complete with unopened sarcophagi and five undisturbed mummies.
