Archimedes was born on 287 BC - 212 BC. His full name was Archimedes of Syracuse. He doesn’t have his full name shown; this is is because we haven’t found documents of his real full name. To everyone he is known as Archimedes of Syracuse. He was a Greek man. The things he was known for were mathematician, physicist, engineering, inventing, and astronomy. Archimedes also made several different types of things that were useful at that time period. He is considered to be the greatest mathematician of antiquity and one of the greatest of all time. He used the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series. He also gave a good estimate of pi.

An important reason why Archimedes is an important person is because of his discovery on the relationship between the surface and volume of a sphere and its circumscribing cylinder. He is known for his formulation of a hydrostatic, which is best known as Archimedes principle. Also he made a device for raising water which is still used in some developing countries. That is called the archimedes screw. Some other important utilities and tools he made were and still important today. For example, one thing was the lever. The lever was used to lift or pull objects. The lever is still used today. This an example of why Archimedes was an important man.

The biggest reason why Archimedes is still known today and is important is because of his math. Archimedes produced formulas to calculate the areas of regular shapes, using a revolutionary method of capturing new shapes by using shapes he already understood. For example, to estimate the area of a circle, he constructed a larger polygon outside the circle and a smaller one inside it. He first enclosed the circle in a triangle, then in a square, pentagon, hexagon, etc, each time approximating the area of the circle more closely. By this so-called “method of exhaustion” , he effectively homed in on a...

...Archimedes (287BC- 212BC)
When people discuss the achievements of the greatest mathematicians of all time, a name that always comes up is Archimedes. Archimedeswas a Greek mathematician astronomer, philosopher, physicist and engineer. He had a reputation in his own time that very few other mathematicians of this period achieved. He is considered by most historians of mathematics as one of the greatest mathematicians of all. His nicknames were, "the wise one", "the master", and "the great geometer." He is credited with a number of important inventions, such as the pi, which is extremely important in mathematical calculations. Other theorems and inventions are attributed to him such as the Archimedes screw, compound pulleys and the lever.
Archimedeswas probably born around 287BC. Archimedes spent most of his life in Syracuse, the principal city-state in Sicily. Archimedes published his works as letters and correspondence with the other great mathematicians of his time, including the Alexandrian scholars Conon of Samos and Eratosthenes of Cyrene. Some of the works which have survived throughout time are the following: On plane equilibriums (two books), Quadrature of the Parabola, On the Sphere and Cylinder (two books), On Spirals, On Conoids...

Biography of a Mathematician
Archimedes, one of the greatest mathematicians, engineers, physicist, inventors, and astronomer's in history. Ranked with the likes of Isaac Newton and Carl Gauss, Archimedes contributions to math include the area of geometry, number theory, algebra, and theorems of plane.
Birth
Archimedeswasborn in Syracuse, Greece on the island of Sicily in 287BC. Son of Pheidias, a well-known astronomer, and research showing that Archimedes is thought to be a relative of King Hiero II. King Hiero II questioned a crown made for him. Archimedes studied the crown and discovered the purity of the gold in the crown. Archimedeswas sitting in a bath house, watching water running from the crown of King Hiero II, observing the pattern of the water, Archimedes figured the excess of bulk with the introduction of certain alloys can be measured by placing the crown with an equal weight of gold in a separate container filled with water. This observation showed the difference of overflow; and the birth of the Archimedes Screw.
Education
Phidias, Archimedes father did not want his son in Syracuse during the times of war, living a life of luxury, Archimedeswas allowed o peruse the finer things in life, education. Greek...

...Archimedes
Water pumps, burning mirrors, levers, war machines, spheres, cylinders, circles, spheroids, or spirals, ever wondered who first thought of them? Where they came from? All of these things were considered during Archimedes life. Not much is known about Archimedes life. Yet he is still regarded as one of the most important scientists of classical antiquity. Archimedeswas a mathematician with much fame whose philosophies became known all over the world. He gained the reputation that he had on his own clock. Not many other mathematicians of his time achieved that accomplishment. Archimedeswas so brilliant that he is still considered by most historians throughout time as one of the greatest mathematicians of all time.
Archimedeswas a mathematician and inventor of Ancient Greece born on 287 B.C. in Syracuse on the island of Sicily. His father was an astronomer named Phidias. It is said that Archimedeswas known to be a relative of Hiero II. Hiero was the king of Syracuse during the life of Archimedes. Throughout their lives they were very close friends. However besides his father’s name and occupation and his relationship with Hiero nothing else is really known about any other members of Archimedes family. At one point of...

“BCS Buster”
The BCS, Bowl Championship Series, has existed in NCAA football since 1998. Created in hopes of eliminating the controversy, the BCS is set to make proper computer rankings of teams based on strength of schedule, games won, and “style” points. Style points are how bad a team has beaten another team, or how much domination the team displays over an opponent. Undefeated season from any team within a BCS conference can guarantee a spot in the National Championship game in January. The BCS conferences include the ACC, Big Ten, Big East, Pac-12, SEC, and the Big 12. All of the other conferences, represented in the NCAA, are called mid-major conferences, and they contain the MAC, WAC, Mountain West, etc. To obtain a spot in the National Championship for teams from these mid-major conferences, it takes a great strength of schedule such as playing multiple teams ranked within the top 25 spots of the rankings, undefeated season containing zero blemishes, major style points, and a prayer that two BCS conference teams will not go undefeated. The University of Notre Dame, labeled as an independent team, due to program success and their influence in the BCS, is also guaranteed a spot in the National Championship game via undefeated season (Dittmore). Although hard to do, it is clearly accomplishable. In the few years of the BCS’ existence,...

Archimedes
Inventions of ArchimedesArchimedes area of expertise was inventions and coming up with great ideas. He was a very smart person, and had invented some useful inventions for human kind for what is still used today. BC. He was a physicist, engineer, inventor, astronomer and a Greek mathematician. Archimedes is one of the greatest math mathematicians of all time. He has been given credit for the invention of the lever even though it was used thousand of years before his time despite the fact that he did not invent it. He only gave an explanation of the principal involved in his work. Once He had made the statement “If I were to have a place to stand, I would be able to move the entire earth”.
Another invention Archimedes had invented was the Archimedes screw. This invention helps to bring water from lower areas to higher grounds by a rotating screw inside a tube constantly. The water is forced out the tube even though the water is at lower ground. This invention is also used today.
Also an interesting invention Archimedes invented was the Heat Ray. This was used to destroy enemy ships by catching a part of the ship on fire then having it burn all the way down. People have tested this invention out to see...

Isolation of the Components of BC Powder
Introduction
Aspirin, Caffeine and Salicylamide were extracted from an over-the-counter pain reliever (BC Powder). These components were separated by manipulating their solubilities by adjusting the acidity and basicity of the solution. By doing this, the three components were forced into conjugate acid (or base) forms, causing selective solubility in either an aqueous or organic solvent. These layers were then separated by use of a separation funnel. Once separated, the components extracted were characterized by measuring the melting point and performing a TLC analysis. Also, the recovered aspirin from the first part of the experiment was recrystallized and compared to that of the isolated aspirin.

The BCS is a scientific framework for classifying drug substances based on their aqueous solubility and intestinal permeability. When combined with the dissolution of the drug product, the BCS takes into account three major factors that govern the rate and extent of drug absorption from IR solid oral dosage forms: dissolution, solubility, and intestinal permeability. According to the BCS, drug substances are classified as follows:
Class 1: High Solubility – High Permeability
Class 2: Low Solubility – High Permeability
Class 3: High Solubility – Low Permeability
Class 4: Low Solubility – Low Permeability
In addition, Immediate Release solid oral dosage forms are categorized as having rapid or slow dissolution. Within this framework, when certain criteria are met, the BCS can be used as a drug development tool to help sponsors justify requests for bio-waivers.
A. Determining Drug Substance Solubility Class
An objective of the BCS approach is to determine the equilibrium solubility of a drug substance under physiological pH conditions. The pH-solubility profile of the test drug substance should be determined at 37 ± 1oC in aqueous media with a pH in the range of...
