Einstein's theory of relativity is a famous theory, but it's little understood. Essentially, the theory of relativity refers to two different parts of the same theory: special relativity and general relativity. The theory of special relativity was introduced first, and was later considered to be a special case of the more comprehensive theory of general relativity. During the nineteenth century, scientists believed that light is a wave. They reasoned that waves of light need a medium to travel through, so they invented the concept of "ether." Light was thought to transmit through the ether, which stands still while all matter moves through it. In order to measure the earth's speed through the ether, Albert A. Michelson and Edward Morley collaborated on an experiment in 1887. In the experiment, one beam of light took a route against the ether and back while the other was perpendicular to the ether. Michelson and Morley expected to calculate the speed of the earth through the ether, to their surprise, the beams of light completed the course in the same time. However, the well-known Michelson-Morley experiment had failed to detect Earth's motion relative to the ether and no one could explain why. Something was wrong with the traditional understanding of relativity as it applied to light. Within this essay we will further explain both parts of the theory of relativity and their relevance in our world.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Albert Einstein’s theories of relativity changed what we originally believed about the physics of our world, and also added new dimensions to our understanding of physics. Einstein combined two previous theories: the Theories of General Relativity and Special Relativity, to create his Theory of Relativity. This theory changed our ideas of how to do rational science. It also added to the basis of modern quantum mechanics by stating that light really comes in little bundles of energy called quanta.
The Special Theory of relativity is an acknowledged physical theory that revolutionized advancements in the relationship between space, and time. The theory is one of the most interesting discoveries that are still used today in science fiction movies such as Star Wars, and Star Trek through the use of black holes, and time travel due to it’s astonishing results, and it occurrence at speeds close to the speed light, which can be appealing to a wide range of audience. This was a harvest from six years of extremely handwork by Albert Einstein. Einstein used resources that were widely available to the public due to his economic constraints. It wasn’t until 1905, when Einstein finally had finished and published his discoveries, and gatherings of previous discoveries from other scientists regarding the special theory of relativity. It wasn’t until the 19th century when Albert’s discoveries were put on a dependable experiment by Maxwell adding to the legitimacy of Einstein’s discoveries. The special theory of relativity is still in use today in modern technological devices such as the GPS, as well as sub-microscopic particle interactions, and motion of stars and galaxies, and cosmology.
Quantum mechanics is the study of the behavior of energy and matter at the atomic, molecular and nuclear levels and sometimes even microscopic levels. The first initial information on quantum mechanics was first discovered in the early 20th century by a pioneering scientist Max Planck, because of this early knowledge of quantum energy it led to the first invention of the transistor. Scientist Max Planck discovered an equation that explained the results of these tests. The equation is as follows, E=Nhf, with E=energy, N=integer, h=constant, f=frequency. In determining this equation, Planck came up with the constant (h), which is now known as "Planck's constant." The word “Quantum” comes from the Latin meaning “how much”, which refers to the units of matter and energy predicted and observed in quantum physics. In day to day life it is understood how the world generally works and how the basic laws of physics come to play. Some examples of this are the following, drop a vase and it will break on the floor due to gravity, push a toy car and it will ride along because pushing something makes it move. Since the turn of the century scientists assumed that all the basic rules of physics applied to everything in nature as well but they did not. Quantum mechanics has also played an important role in technological advances that make modern life possible. Without it the first transistor would not have been invented or the personal computer or laser, and hence no Blu-ray players. Author James Kakalios mentioned in an interview regarding his book titled The Amazing Story of Quantum Mechanics that if you understand and accept the following three ideas, a light is a photon, matter has a wavelength nature associated with its motion and tha...
In the original time travel novel, The Time Machine by H.G. Wells, the main character is sent on an extraordinary journey to the future. In this 800,000 year journey The Time Traveler, as he is known in the book, faces many new challenges and sees many new sights. Paralleling this fictional story, time travel is becoming a new focus of study. Time travel, a supported theory by many world-renowned physicists, is a widely debated topic in modern times. However, to fully understand this debate, a small lesson is needed.
Do we live in a world with a reality that is independent of the observer, which can be assessed objectively and compared to an observer’s perceptions? Or do we live in a world that has a reality dependent on the consciousness of the observer? The two most successful scientific theories do not agree on the role of the observer in reality. The Theory of Relativity implies that there is an observer-independent reality whereas The Copenhagen Interpretation of Quantum Mechanics implies an observer-dependent reality. In this paper, I will critically examine the views of both and evaluate what our observation can tell us about the world.
What would happen if he could ride alongside abeam of light, was the question that Albert Einstein asked himself in 1894. This simple question was a question that eventually led Einstein to formulate his theories on relativity. Ten years were all it took Einstein to have two theories regarding spacetime; the theory of special relativity and the theory general relativity. The theory of special relativity is the theory that unifies time and space, while the theory of general relativity explains gravity as the curvature of spacetime.
A hundred years ago, a young married couple sat at a kitchen table talking over the items of the day while their young boy sat listening earnestly. He had heard the debate every night, and while there were no raised voices, their discussion was intense. It was a subject about which his parents were most passionate - the electrodynamics of moving bodies in the universe. The couple were of equal intelligence and fortitude, working together on a theory that few people can comprehend even to this day. Mileva Maric Einstein was considered to be the intellectual equal of her husband Albert, but somehow went unrecognized for her contributions to the 1905 Papers, which included the Special Theory of Relativity. The stronger force of these two bodies would be propelled into the archives of scientific history, while the other would be left to die alone, virtually unknown. Mrs. Einstein was robbed. She deserved to be recognized for at least a collaborative effort, but it was not to be. The role which society had accorded her and plain, bad luck would prove to be responsible for the life of this great mathematician and scientist, gone unnoticed.
Quantum mechanics describes several objects and phenomena that seem strange and are difficult to understand. Among these are quanta “chunks” of energy; the wave-particle duality of matter; and the uncertainty principle which limits what we can know about objects. In 1927, German physicist Werner Heisenberg discovered a general characteristic of quantum mechanics, the uncertainty principle. According to this principle, it is impossible to precisely describe both the location and the momentum of a particle at the same time, therefore it affects the attempts to measure a particle’s location and
