Einstein’s Theory of Relativity 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.
What Are These Theories? The General Theory of Relativity demonstrates that time is related or linked to matter and space (AllAboutScience). For example, a period of time for someone on Earth that lasts for hundreds of years might only be a couple of hours for someone speeding around in a rocket at nearly the speed of light (IFLScience). Another example is the

One consequence was relative simultaneity, two event, simultaneous for one observer, may not be simultaneous for another observer if the observer is in motion. The relativity of simultaneity is closely related to the constancy of the speed of light. For example, imagine two trains, A and B, moving relatively at half of the speed of light. A flash bulb is triggered in the exact center of one of the A-train cars. Since the speed of light is the same in all directions to the A-observer, the light strikes the ends of the car, which are 10 m away from the center, at the same instant in the A-frame. However, to the B-observer, the A-car moves forward so that its front wall moves away from the moving light signal and its back wall moves toward the light. Since the speed of light to B is unaffected by the relative motion of A, the light hits the back wall before it strikes the front wall. Another consequence is length contraction. Objects are measured to be shortened in the direction they’re moving with respect to the
Albert Einstein is looked at as one of the most magnificent scientific thinkers throughout history. His theories on the nature and dimensions of time and space immensely changed the way people thought of the physical world and established many of the major fundamental foundations for a tremendous amount of the our scientific discoveries and inventions in the 21st century.
Since his birth, Albert Einstein has had the most beneficial effects on the events of the world. Albert Einstein was born in Ulm, Germany on March 14, 1979 and as a boy displayed an unquenchable curiosity for understanding science and all of its mysteries. As Albert Einstein’s life progressed, he found himself working as a patent clerk in Bern. While working as a patent clerk in Bern, Albert Einstein had a plethora amount of time which was devoted to formulating his theories. Also during this time, Albert Einstein received his Doctorate degree and started working on one of his most influential papers, which was the Special Theory of Relativity. After Einstein completed his Special Theory of Relativity, he moved onto creating the General Theory of Relativity which earned him the Nobel Prize in Physics in 1921. With the creation of both the General Theory of Relativity and the Special Theory of Relativity, Einstein was able to create his Theory of Relativity which comprises of both theories. Other scientific discoveries that Einstein made are the existence of the photon, the theory of Brownian motion, the concept of Mass-energy equivalence, the photoelectric effect, the first quantum theory of specific heats, the Einstein-Brilloui-Keller method for finding the quantum mechanical version of a classical system , Bose-Einstein statistics and Bose-Einstein condensates, the EPR paradox, and although his efforts were unsuccessful, in his last thirty years of life Einstein explored various classical unified field theories that could account for both electromagnetism and gravitation and possibly quantum mechanics.
The influence of relativity on the traditional physics is it lead physics to a new level and changed our mind thoroughly. The principle of special relativity pointed out that both the Newtonian mechanics and Maxwell’s electrodynamics are covariant of Lorentz transformation so they can be unified. And the principle of general covariance which extended out from general relativity lead physics to the no-inertial system. So at both special and general level, the theory of relativity logically made physics into a perfect complete scientific system.
The Theory of Relativity, proposed by the Jewish physicist Albert Einstein (1879-1955) in the early part of the 20th century, is one of the most significant scientific advances of our time. Although the concept of relativity was not introduced by Einstein, his major contribution was the recognition that the speed of light in a vacuum is constant and an absolute physical boundary for motion. This does not have a major impact on a person's day-to-day life since we travel at speeds much slower than light speed. For objects travelling near light speed, however, the theory of relativity states that objects will move slower and shorten in length from the point of view of an observer on Earth. Einstein also
Throughout Albert Einstein’s lifetime he accomplished many amazing things that have an effect on people today. For example, in 1905, “often called as Einstein’s “miracle year”, he published four papers in the Annalen der Physik, each of which would alter the course of modern physics” (Michio,Kaku 13). Throughout Einstein’s four books, he “applied the quantum theory to light in order to explain the photoelectric effect, offered the first experimental proof of the existence of atoms, laid out the mathematical theory of special relativity, and proved the first mechanism to explain the energy source of the Sun and other stars”(13). Throughout 1905-1915 Einstein began to realize that his theory for relativity was flawed, because “it made no mention of gravitation or acceleration” (19). “In November of 1915, Einstein finally completed the general theory of reality” (20); “in 1921 he won the Nobel Prize in Physics” (Belanger, Craig. 1).
Many scholars, researchers, and scientist claim that the greatest discovery in mankind’s history was actually made by Professor Albert Einstein and is called the “Theory of Relativity.” The reason they say this is that by being able to explain and understand how everything relates to everything else is the key to advancing or evolving our knowledge about everything. In other words if we know how a starfish relates to a star, in theory we can know or cause to be known everything in-between. So the very evolution of knowledge is at stake, never mind the methodology that is used.
Greene continues with his explanations of the special theory of relativity.Chapter 3: Of Warps and Ripples Green begins the chapter by describing "Newton's View of Gravity" and continues by discussing the incompatibility of Newtonian Gravity and Special Relativity. The author also talks about how Einstein discovered the link between acceleration and the warping of space and time. Greene also discuses the basic aspects of General Relativity. He later points out how the two theories of relativity effect black holes, the big bang, and the expansion of space.Chapter 4: Microscopic Weirdness This chapter describes, in detail, the workings of quantum mechanics.
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.
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.
This disproves time because if time was tangible then it would have to be constant and apply to all things at once rather than only affect things based on perspective. One of the reasons why time is relative is due to the fact that on a cosmic scale time is determined by isolating a section of space and then using a relationship between a number of parts like a solar system to determine the clock for that section.The reason why time is determined like this on a cosmic scale is due to the fact that the universe is constantly expanding infinitely which creates the paradox of certain parts being older than others but equally as old because they are part of the same universe. Another reason why time is relative is due to the fact that similar to a DVD when a movie is being watched
In 1905, Albert Einstein wrote his paper on the special theory of relativity (Prosper). This theory has the reputation as being so exotic that few people can understand it. On the contrary, special relativity is simply a system of kinematics and dynamics, based on a set of postulates that is different from those of classical mec...
Sir Isaac Newton came up with many theories of time and space. Euclid said that there can be a concept of a straight line but Newton said nothing could ever travel in a straight line, see illustration below.
Humans have a natural sense of curiosity. How does this work? Why does that happen? What makes this do that? Among us, there will always be those who strive to find the answers to questions like these and more. One of these people was Albert Einstein, perhaps one of the greatest human minds this world has ever known.
Time is defined in the dictionary as “the indefinite continued progress of existence”. Einstein is credited with time being referred to as the fourth dimension when in terms of science. Ever since the first humans lived to now, time has always been an important part to life. We began to classify time and name certain sections of time by the length of how much time it has taken. These different sections are words that we hear almost daily, such as days, months, and years. The words are then used to clearly understand the span of a li...
Yes, many people have heard of Albert Einsteins General Theory of Relativity, but few people know about the intriguing life that led this scientist to discover what some have called The Greatest Single achievement of human thought!
