What was Pierre Simon laplace's childhood?
He was very short, his weight was very low, and his voice was quite high. His parents ...
Mme. and Msr. de LaPlace ... being quite inexperienced in the business of parenting, were
beside themselves with worry over this seemingly insurmountable combination of handicaps.
Coupled, as his condition was, with his inability to do almost anything productive ... math,
chemistry, physics, bricklaying, wood-chopping, water-hauling, etc. ... his parents were
firmly convinced and resigned to the tragic conclusion that short, light, squeeky Pierre Simon
would never amount to anything, and would have to be institutionalized and cared for in
perpetuity.
They were in the process of making plans for the trip to perpetuity, to get him registered
and settled in there, when a cousin happened to drop by for a visit, and gave them a
piece of news that changed their lives, not to mention the life of little Pierre. This cousin
was schooled in the ways of the Scientific Method, and had dedicated his life to scientifically
and methodically observing everything around him, and in so doing to discover patterns,
systems, and the ways of nature and of the world.
This old, worldly, and wise cousin was the first to draw their attention to the vast numbers
of other short, light, squeeky people living in their village ... short people who could do
no more of value than little Pierre could, and who spent their days running aimlessly in
the streets, terrorizing the animals, dirtying their clothing, shouting at each other, throwing
stones and sticks about, and generally driving their parents to regret the whole thing.
The cousin showed them that little Pierre's condition, while seemingly hopeless, was
actually universal, and would change with time.
To make a long story brief, the truth set little Pierre's parents free, and they became totally
transformed. Where time had previously been their enemy ... where every second felt
like an hour and every day seemed a year ... their boy now became their greatest joy.
While there was still nothing they could do to cure the state of dehydration that had
inspired his name, Pierre now inspired them to create even more short, light, squeeky
people, and they did so as often as was humanly possible.
Their domain was magically transformed, from one of time to one of frequency, and little
Pierre, the dehydrated French child, grew to become a longer, heavier, famous great
basso mathematician.

Give mathematical experssion for pascal triangle?
See link at bottom. Pascal's triangle begins with a 1 at the top. This is row 0. The first row of Pascal's triangle 1,1 corresponding to n = 1 and i = 1 and 2. The second row of Pascal's triangle is 1, 2, 1, corresponding to n = 2 and i = 1, 2, 3 If we have (x+y)^2, we have (1) x^2 + (2)xy + (1) y^2 so Pascal's triangle gives the constants in front of the variables. Also, ai = n!/[i! x (n-i)!] Example, 5th row third element is 10, which is calculated as 5!/[3! x 2!] = 5 x 4/2 = 10. http://en.wikipedia.org/wiki/Pascal's_triangle
