It is apparent that, during certain areas of history, the atomic models repetitively questioned as new material became available in the study of that field. Specific concepts begin to elevate themselves above others and become dominant as they begin being experimented on. Judging by the the literature on the development of the atomic model, the first speculations began around the ancient Greek and Roman times. The Greek and Roman philosophers speculated, what is the nature of matter, or what is this stuff made up of? The Greek philosopher, Democritus, offered his atomic theory as the answer to their questions. Democritus’ atomic theory States that all matter consists of invisible particles called atoms. It also states that atoms are indestructible, …show more content…
Albert Einstein provided a significant and powerful confirmation, in 1905, that atoms and molecules actually exist through his analysis of Brownian motion. One of Albert Einstein 's most known contributions is the mass Energy equivalents equation. The energy equivalence equation is E = MC2 or Energy = Mass x (speed of light)2. this equation states that a little mass can generate quite a bit of energy, Because the mass is being multiplied times the speed of light which is being squared. The speed of light in vacuum is equal to 300,000 kilometers per second. Einstein also contributed greatly to the photoelectric effect. He saw that if you shine a light on metal it release electrons. Because of this Einstein said that light is made up of individual particles of energy called quanta. He theorized that when quanta hit the metal, the energy from it was transferred to the electrons giving the electrons enough energy to escape the nucleus is of the atoms in the metal. One of the other things Einstein is known for is Einstein 's theory of special relativity. Einstein began to wonder how to resolve Newton 's laws of motion with Maxwell 's equations of light. He solve this by imagining how the world would look if he could travel at the speed of light. He began to think that if you move towards a ray of light as it approaches you or if you move away from a ray lights, the ray of light would still be moving at the exact same speed no matter what. The ray of light will always move at the speed of light. It does not matter if you are moving towards the light or away from the light will meet you at the same time no matter what. Einstein then concluded that time, length, and mass depend on the speed we are moving at. In other words the closer you are to the speed of light the bigger the difference you see in the quantities compared to someone moving
In 1803 this theory was finalised and stated that (1) all matter is made up of the smallest possible particles termed atoms, (2) atoms of a given element have unique characteristics and weight, and (3) three types of atoms exist: simple (elements), compound (simple molecules), and complex (complex molecules).
Dalton’s atomic theory, which stated “the atoms were tiny, indivisible, indestructible particles” (Bender), differed drastically from that of the Greeks’ in that it “wasn’t just a philosophical statement that there are atoms because there must be atoms” (Bender). Although Aristotle believed that there are four terrestrial elements, earth, water, air, and fire, Democratus believed that “a piece of a substance can be divided into smaller pieces of that substance until we get down to a fundamental level at which you can’t divide the substance up and still have pieces of that substance” (“Atoms”). Aristotle’s theory was popular, but incorrect; Democratus’s was closer to our current theory, yet he remained relatively unpopular and obscure. This demonstrates of the key way in which a personal point of view can, in fact, retard the pursuit of knowledge. The scientist with the better oratory abilities has his theories more widely accepted. Dalton’s own theory, which extrapolated upon four basic

First, special relativity describes the laws of motion of an object which moves at high speed. Meanwhile it offered the mass-energy relation which is E=mc^2 (E=energy m=mass c=speed of light). Although Einstein didn’t believe in quantum mechanics2, his mass-energy relation still helped in the establishment of it. Also this relation built the mathematical model ...
The main theory of the day, with regard to physical science, was Atomism. Atomists believed that bodies are made from minute particles. Further, they believed that the particles and the bodies made from them, possess primary and not secondary properties. The most important exception from this viewpoint was that of Descartes. Although he rejected atomism, he did agree that bodies only really possess primary qualities. Basically what this means is that bodies in themselves possess shape, size, motion and impenetrability but not colour, sound, taste, hardness or smell. This latter g...
The imminent threat of war pulled the trigger on the atomic race as it became clear that whoever could split the atom could build the atomic bomb, and whoever could build the bomb could win the war. During the mid-1900’s there were only three countries capable of splitting the atom: Germany, Japan, and the United States. The United States was able to win, but had it not have been for the sabotage of Vemork, and the saving grace of some of the greatest scientists of our time, the outcome of WW2 could have been drastically different.
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
The mastermind albert einstein was one of the brightest men known to ever live. He seemed to understand things on a level no one else could comprehend. However was albert einstein to blame for the atom bomb’s destruction? Albert discovered the formula for the most incredible bomb ever seen. Without the formula there would be no atom bomb. Albert einstein sent a letter to president roosevelt on August 2nd, 1939 regarding the atom bomb and the danger of it. Although Albert Einstein is a scientist and was in no position to make government decisions, Einstein's letter to president roosevelt resulted in an investigation, decision, and an explanation of e=mc^2 of the atom bomb.
The Atomic Theory began in roughly 400BC with Democritus in Ancient Greece and is universally believed to be correct today. Democritus who was born in 460 BC and died 370 BC and is known as the father of modern science. Democritus proclaimed that everything is made up of atoms. He continued his theory to say that atoms will always be in motion, between atoms there is empty space, atoms are unbreakable, there are an infinite number of atoms all different sizes and shapes. He also said that iron atoms are solid and strong and have hooks to lock them together, water atoms are smooth and slippery, salt atoms have sharp jagged edges because of its taste and air atoms are light and spiralling.
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.
The year is 1938. War is plaguing Europe. The German military, under the direction of Adolf Hitler, was ruthlessly invading European countries attempting to create a larger and more powerful Germany. While this was happening, the world of theoretical physics was on the brink of an incredible discovery: splitting atoms, the building blocks of all matter, could result in enormous amounts of energy being released. The Germans were leading this cause, but letting Hitler gain control of a possible weapon of mass destruction could be devastating. The stakes were at an all-time high due to the mystery involving the power of splitting atoms. What was not known at the time was what this race for controlling science would build up to. The development and use of the world’s first atomic bomb brought up many questions about the rights and responsibilities of nuclear and atomic science.
Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose name is known by almost all living people. While most of these do not understand this mans work, everyone knows that his impact on the world is astonishing.
Democritus was the leader of a group called Atomists. Although they were unable to prove that matter was made up of small particles, they were the first to come up with the idea. Democritus believed that atoms differed in size, shape, and movement but were all made of the same substances. Aristotle was the most important scientific philosopher in Greece. He believed that all matter on earth consisted of four pure substances or elements, which were earth, air, fire, and water. He also believed that the earth was the centre of the universe, and that anything beyond the earth consisted of a fifth pure substance called quintessence. Archimedes was an inventor and mathematician, who discovered several basic scientific principles and developed a number of measuring techniques. Ptolemy was an Egyptian astronomer. He developed a model for predicting the positions of the sun, moon, stars, and planets. Like Aristotle, he believed that the earth was the center of the universe. Between 400 AD. and 1000 AD.
Dalton was the first person to develop a scientific atom theory, the ancient Greeks had ideas about the atom but could not prove it scientifically.
Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
