Blaise Pascal Essay, Research Paper

Hydrodynamics pertains to the branch of fluid dynamics that deals with liquids. Hydrostatistics deals with the branch of hydrodynamics dealing with statics of fluids, especially the equillibriumand pressure liquids. Pascal invented the syringe, perfected barometer, and the hydraulic press. The hydraulic press is based on the principle of the area times the distance pressed is eqaul to the force, which applies to the machine that permits a small force applied to a small piston to produce, through fluid pressure, a large force on a piston(A x DP=F). Pascal also had some part in the invention of the Hydraulic Lift, due to the fact that it is an of Pascal’s Law . It works on the principle that effort required to move something is the product of the force and distance the object is moved. Pascal’s Law states that pressure applied to a contained liquid are transmitted unreduced throughout the liquid irrespective of the area over which pressure is applied. When a fluid is at rest, a force perpendicular to any surface in contact with it, allows the container wall or the surface of a body imersered in it . Pressure is force per unit area. The SI unit of pressure is the pascal.1 pascal= 1N/m Pascal ha also came up with a arithmatical triangle known as Pascal’s Triangle: an arrangement of numbers that were used to calculate binomial coefficients. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 11 5 10 10 5 1 It is constructed by adding to adjacent numbers in a line and putting thier sums between them, but on the next line down it is convienient to straighten out the left side of the triangle and to label the rows accurately by n= 1,2,3, and so on. The same follows as for labeling the column r= 1,2,3, and so on. Each entry is the sum of the one above it together with the the one above it and to the left. If all the blank spaces are thought of as zero’s, then it counts for all rows to be n=1 and on. The entry on the nth row and rth column is called C(n,r) are binomial coeficients, since they appear in the binomial theorem. The familiar fomula is (x+y) = x +2xy =yIt has coefficients of 1,2,1 on the right side. These are the row n=2 simalarily to (x+y) = x +3x y+3xy +y Pascal was one of the most eminent mathematicians and physcist of this day and one of the greatest mystical writers in Christian literature. He reasoned that the value of eternal happiness is infinite and that the probability of gaining such happiness by religion may be small, but is infinitely greater than any other course of human conduct or belief. Pascal’s most famous work, The Pensees, a set of deeply personal medatations in somewhat fragmented form on human suffering and faith in God. Pascal’s wager expresses that the conviction that the belief in God is rational: If God does not exist, one stands to lose nothing by believing in him anyway, while if he does exist, one stands to lose everything by not believing. On the night of November 23, 1654 “from aproximately ten-thirty till half past midnight,” a great change came over Pascal.(Given a mystical vision of God, he was enjoined to renounce the world and surrender to Jesus Christ.) At the age of 39, Pascal was in intense pain after a malignant growth in his stomach, which eventually spread to his brain. He no longer could bare the pain, and died suddenly on the night of August 19, 1622. Pascal’s discoveries and experiments still help people today in thier every day lives. He was an outstanding mathematician and phycist, who has left a significant impact in history.
