There were many. He is famous for the saying, "If I had a lever big enough I could move the world." Actually, a more accurate translation would be: If I had a firm enough place to stand, I could move the world.
He is also most known for hi invention of the Archimedes screw for pumping water.
Archimedes' principleMain article: Archimedes' principleArchimedes may have used his principle of buoyancy to determine whether the golden crown was less dense than solid gold.
The most widely known anecdote about Archimedes tells of how he invented a method for determining the volume of an object with an irregular shape. According to Vitruvius, a votive crown for a temple had been made for King Hiero II, who had supplied the pure gold to be used, and Archimedes was asked to determine whether some silver had been substituted by the dishonest goldsmith.[15] Archimedes had to solve the problem without damaging the crown, so he could not melt it down into a regularly shaped body in order to calculate its density. While taking a bath, he noticed that the level of the water in the tub rose as he got in, and realized that this effect could be used to determine the volume of the crown. For practical purposes water is incompressible,[16] so the submerged crown would displace an amount of water equal to its own volume. By dividing the mass of the crown by the volume of water displaced, the density of the crown could be obtained. This density would be lower than that of gold if cheaper and less dense metals had been added. Archimedes then took to the streets naked, so excited by his discovery that he had forgotten to dress, crying "Eureka!" (Greek: "εὕρηκα!," meaning "I have found it!"). The test was conducted successfully, proving that silver had indeed been mixed in.[17]
The story of the golden crown does not appear in the known works of Archimedes. Moreover, the practicality of the method it describes has been called into question, due to the extreme accuracy with which one would have to measure the water displacement.[18] Archimedes may have instead sought a solution that applied the principle known in hydrostatics as Archimedes' principle, which he describes in his treatise On Floating Bodies. This principle states that a body immersed in a fluid experiences a buoyant force equal to the weight of the fluid it displaces.[19] Using this principle, it would have been possible to compare the density of the golden crown to that of solid gold by balancing the crown on a scale with a gold reference sample, then immersing the apparatus in water. The difference in density between the two samples would cause the scale to tip accordingly. Galileo considered it "probable that this method is the same that Archimedes followed, since, besides being very accurate, it is based on demonstrations found by Archimedes himself."[20]
Aristotle (Greek) (384 BC - 322 BC) was a Greek philosopher, a student of Plato and teacher of Alexander the great. He wrote on many different subjects, including physics, metaphysics, poetry, theater, music, logic, rhetoric, politics, government, ethics, Biology and zoology.
Contributions of Aristotle
While Aristotle's contributions in each subject were considerable for the time, his major contribution was to the overall study and teaching of such subjects, many of which had never been considered before. Two areas which he advanced, which are of particular interest to readers of this site were physics and astronomy. He made very interesting discussion OS the topics of matter, change, movement, space, position, and time as well as studying comets.
Aristotle was forced to mave one more time during his lifetime. Alexander the Great died in 232BC, leaving behind strong feelings in Athens. Thanks to his ties to Macedonia, Aristotle was forced to retire to Chalcis, his mothers homeland, where he moved into a house once owned by his mother which still belonged to her family. He died there one year later at the age of 62, after complaining of stomach problems.

what are the contributions of Aristotle to physical science
application of archimedes' principle of specific?
In 212 B C Archimedes found buoyancy.
he was percieved as a very intelligent person who was very smart. People admired him for his contributions to science
Albert Einstein is primarily known for the Theory of Relativity (which comes in two parts, Special Relativity and General Relativity). He made enormous contributions to science in the 20th century.

Archimedes.
He was the only one that came close to determing the value of pi.
