Important Discoveries in Physics Essay - 2329 Words

Ideas in the subject of Physics are never absolute; it is a forever-changing topic. We think we have discovered everything there is to know about it, and then we find out something new that changes everything. That is one of the reasons physics is so interesting to learn about – there will always be something new. There are many very important discoveries in Physics. This paper will describe some of the discoveries. These discoveries are prevalent throughout history and in our daily lives. One of the oldest, but nonetheless important, discoveries in physics is The Law of Falling Bodies. Discovered by Galileo Galilei, it remains a fundamental part of physics even today. It states that all objects that are falling, no matter mass, height,†¦show more content†¦If they were not important then people would not have heard so much about them. Isaac Newton was a mathematician and physicist that discovered the three laws of motion. The laws are as follows: â€Å"1) An object in motion remains in motion unless an external force is applied to it. 2) The relationship between an objects mass (m), its acceleration (a) and the applied force (F) is F = ma. 3) For every action there is an equal and opposite reaction.† With these three laws, Newton created the basis for modern day engineering. These laws helped many other physicists to discover meaningful things. Newton’s first law of motion is usually referred to as the law of inertia. Inertia is defined as â€Å"the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is notShow MoreRelatedThe History of Physics Essay1534 Words   |  7 PagesThe History of Physics In order to attempt to trace the origins of the modern science that we now refer to as â€Å"physics,† we must begin with the origin of the term itself. Taken from the Greek word â€Å"physika† meaning growth or nature, physics most obviously began as the intelligent study of the human environment (Webster 393). From superstition and religious practices, the foundation of all other sciences was born. These concepts have subsequently grown into what we regardRead MoreEssay about Enrico Fermi and the Development of the Atomic Bomb1013 Words   |  5 PagesEnrico Fermi and the Development of the Atomic Bomb The 20th century saw many important discoveries which impacted people worldwide. Great discoveries were made in the realm of science and technology which lead to the atomic age. One of the leading pioneers in the area of physics was Enrico Fermi. Without his contributions, the atomic bomb may not have been developed or would have possibly been postponed. Enrico Fermi was born into a family who had enough money to live comfortably. FermiRead MoreAlbert Einstein s Theory Of Relativity And The Father Of The Atomic Age1174 Words   |  5 PagesThroughout his career, he developed many names for himself. Most notably, he was known as the father of relativity and the father of the atomic age. These two titles alone speak volumes about his achievements and contributions to science, but it is important to examine how he got his name in the history books, and how he made such a big name for himself in his seventy six years of life. Most people know him for his theory of relativity, and the famous formula: E=mc2, but his contributions to scienceRead MorePhysics 11373 Words   |  6 Pagesnotable discoveries were in the field of astronomy, we cannot label him simply as an astronomer. He authored many important works including, Sidereal Messenger (also known as Starry Messenger), but unfortunately, due to the power of the Catholic church in h is native Italy, his work in astronomy was widely rejected by his countrymen. His contributions to physics also place him in the ranks of the greatest scientists of all time. Without Galileo’s contributions to astronomy, mathematics, and physics, weRead MoreAlbert Einsteins Journey to Become one of the Most Well-Known Scientists in History678 Words   |  3 Pagesearning his doctorate and most importantly, thinking. Albert Einstein was destined to change the world with his Theory of Relativity to his discoveries in the scientific world. Born in Ulm, Wà ¼rttemberg, Germany to Hermann and Pauline Einstein, Albert Einstein immediately began life with his family in a tough situation. Einstein was born on March 14, 1879 (â€Å"Physics†). Soon after being born, the family had to relocate to Munich, Germany, because his father had lost his job in Ulm. In Munich his fatherRead MoreThe Nature And Process Of Science1542 Words   |  7 Pageslight doesn’t travel through a medium. Einstein proved this by figuring out that the speed of light was constant, and in order for ether to be the medium light waves travel through, the speed of light would change depending on the observer. This discovery was one piece of the Specific Theory of Relativity. The nature and process of science are a collection of things, ideas, and guidelines. â€Å"The purpose of science is to learn about and understand our universe more completely† (Science works in specificRead MoreJ.J. Thomson1052 Words   |  5 PagesJ.J. Thomson Joseph John Thomson was born in Manchester, England in 1856. Thomson was indeed a good scientist, but he did not know that at first. He attended college at a time when science was finally getting recognized as an important subject (Morgan). Thomsons road to becoming a scientist was not paved for him from the start, as his father had other plans for him. Joseph was intended to become an engineer, but when the time came to pay for his studies, his family could not make ends meet. InsteadRead More Wilhelm Conrad Rontgen Essay1182 Words   |  5 PagesThey had no children, but in 1887 they adopted a daughter, Josephine Bertha Ludwig, who was the daughter of AnnaÕs only brother. RÃ… ¡ntgen spent most of his years researching physics, thermology, mechanics, and electricity. Although he made some great discoveries in all these fields, his greatest invention was the discovery of a short-wave ray in 1895, which we know now as X-rays. Some other things he studied were the heats of gasses and fluids, the characteristics of quartz, the modification ofRead MoreCan Science Prove the Creation of the Universe? Essay1729 Words   |  7 Pagessomeone could tell you the answer to how it all began, how our world was created, why we exist, would you want to know? Modern Science has made some pretty impressive discoveries about our universe. As stated by George Smoot, a cosmologist at the University of California at Berkeley and winner of the 2006 Nobel Prize in physics, â€Å"I think we all know where we came from and how we fit into the world, but some of us need to know how it all works in great detail.† While some people believe testingRead MoreEssay on Erwin Schrà ¶dingers Valuable Contributions1133 Words   |  5 PagesErwin Schrà ¶dinger was a very influential physicist that made many scientific discoveries involving wave mechanics and various contributions pertaining to quantum theory (â€Å"Erwin†). Schrà ¶dinger’s life commenced August 12, 1887 in Vienna, Austria, and from there he led a very noteworthy childhood (Abbott 145). Throughout Erwin’s life, he conducted an exponential amount of research, experiments, and scientific discoveries that benefited society (â€Å"Stuewer†).
