Archimedes discovered Density when he was set on a mission to figure out if a craftsman had given the king a pure gold crown or had defrauded him with silver instead. Archimedes pondered this when he was in a pool. When he slipped himself into the pool he realized that some water had spilled over. Archimedes then had an epiphany and realized that the amount of water that spilled over was equal in volume to the space that his body took up. Archimedes then applied this epiphany to differentiating whether the king's crown was silver or gold. Archimedes put the Craftsman's crown and a pure gold crown of the same mass in two tubs of water. He observed that more water spilled over the sides of the tub when the craftsman's crown was submerged.
Odysseus returns home and seeks revenge on the suitors that plague his wife. In order for him to be successful with the revenge he must use his cunning, knowledge of battle and his desire to be with his wife Penelope.
Archimedes principle says that the magnitude of the buoyant force always equals the weight of the fluid displaced by the object. This buoyant force always acts upward through the point that was the center of gravity of the displaced fluid. In the case of floating objects the buoyant force is equal to the force of gravity on the object. Knowing that the change in pressure is equal to the Buoyant force per unit area (ΔP = B/A) we see that B = (ΔP)A and ΔP = ρgH where ρ is the density of the fluid g is the acceleration due to gravity and H is the height of the fluid displaced.

Archimedes. The first one is the Archimedean screw which supposedly could serve as a water pump. The second invention was the compound pulley. The third invention
~ In the 17th century, Galileo inferred that there was a relationship between mechanical forces and bone morphology, when he noted that body weight and activity were, related to bone size. ~
Aeschylus’ Prometheus Bound portrays a greek god detained by a superior for disobedience against the latter’s rule. On the other hand in Euripides’ Hippolytus portrays lust and vengeance of the gods and the extent that they can go to to avenge it.
The volume of air can be calculated using the equation Vv = VA +Vw. The volume of water can be calculated due to the knowledge that Vw = Mw, Mw = w/100 x Ms and Ms = ρdV.
He loved mathematics so much and he dedicated the rest of his life to the research of mathematics, building, machines and mechanisms. During that time, there were absence of paper and blackboard. However, it did not be an obstacle for Archimedes to feed in more knowledge. He used sand, dust, ashes or sand to study ...
that yields no solution and conscious thinking will not help you." No matter how much thinking you do if you are stuck thinking about it for long periods of time will not help you. The real answer will come to you when you think you are not thinking. By taking your mind off the bigger picture you will discover the answer while doing a task that is unrelated to the subject. This is what made Asimov develope the Wureka Phenomenon. Asimov further explained this by giving the reader multiple examples one of them being the crown made for Hieron II. The king was afraid that he had been tricked and that all of the gold he had given to the goldsmith hadn't all been used in his crown and substituted with an inferior metal, copper that was much less valuable. Archimedes, a Greek scientist and philosopher, was called in on the problem. At the time the only way to measure volume was to completely destroy the crown but the king would not allow that. Archimedes pondered how he would change the way to measure volume and got nowhere. He went to the public baths and noticed how water splashes out when he gets in the bath. As the water spilled out he discovered the modern use of finding volume in irregular objects such as a crown.
Swiss scientist Daniel Bernoulli discovered that the pressure of a moving fluid is different than the pressure of a fluid at rest in the 1700’s. A fluid usually flows from areas of high pressure to areas of low pressure. Additionally, his principle states that the faster a fluid moves, the less pressure the fluid exerts. Furthermore, the cause of an acceleration of a fluid is due to the fluid moving in a horizontal direction encountering a pressure difference, resulting in net force. In conclusion, Bernoulli’s principle is a concept of fluid dynamics.
The concept of buoyancy states that the upward force of an object immersed inside a fluid is equal to the amount of weight of the fluid it has displaced. The concept is also known as the Archimedes’ principle. After the mathematician, inventor and physicist Archimedes discovered it(Buoyancy - Concept, How it works 2014).
In the past age, there were many explorations into the deep sea. Scientists originally descended in order to find the kraken and the giant squid. In the modern era, scientists travel to the deep to discover slightly smaller creatures. Microbial organisms are the most abundant life form on Earth. Scientists drill for microbes on the ocean floor where ancient remains still exist. Other scientists no longer look for life, their interest is in minerals that can produce pharmaceutical drugs. In fact, many drugs have been discovered this way.
...ere are nothing left except a number of stories, which, although not literally accurate, but help us to conception of the personality of one of the greatest mathematician of antiquity which we would not willingly have changed. The inventions and formulas built the frame of fluid mechanics and even today these are the basis of contemporary science. We can surely say that Archimedes is one of the greatest scientists of all times.
This device was consequential to mechanical philosophy because it was an attempt by Boyle to explain the underlying nature of the vacuum. Boyle was attempting to understand and reproduce the results of a Torticillian vacuum. In 1643, Evangelista Torricelli found an empty space in a sealed glass tube above the mercury in his newly invented barometer. Philosophers across Europe tried to devise ways of establishing the properties of a ‘Tortecellian vacuum'. To investigate this new and conspicuously instrument-generated phenomenon of nature, however, it would have to be necessary to make a vacuum that was physically larger and more accessible than that inside a barometer. Mechanical philosophy pervaded every aspect of Boyle's work on the air pump, even his descriptions, which he elucidated in his 1660 work entitled New Experiments Physico-Mechanical, Touching the Spring of the Air, and its Effects. In it he states: Your Lordship will easily suppose, that the notion I speak of is, that there is a spring, or elastical power in the air we live in. By which… spring of the air, that which I mean is this: that our air either consists of, or at least abounds with, parts of such nature, that in case they be bent, and as soon as those bodies are removed or reduced to give them way."
