Dr. Erwin Schrodinger was a physicist in the twentieth century. He made groundbreaking discoveries in his field, for which he earned the Nobel Prize in 1927. Schrodinger was also a published author and remains a well-known scientist today. Schrodinger devised what is known as the “Schrodinger’s Cat Paradox” in 1935. It was one of his later discoveries and was worked on after extensive correspondence with Albert Einstein. Dr. Schrodinger earned his PhD in physics in 1910 from the University of Vienna in Austria. Though the Schrodinger Cat thought experiment is well known, Schrodinger earned his Nobel Prize for work on the movement of electrons (known as ‘Schrodinger’s Wave Theory’) in 1927. The Schrodinger’s Cat paradox was devised while he worked at the University of Graz in Austria. The thought experiment was an advancement in the field of quantum physics. Quantum physics is a theoretical branch of physics that deals with the behavior of matter and energy at a nanoscopic level. Specifically, the paradox was formulated to discredit the Copenhagen Interpretation of quantum mecha...
In 1950, a man, Enrico Fermi, during a lunch break conversation he causally asked his co-workers an interesting question, “where is everybody”. (Howell, 2014) By which he meant, since there are over a million planets which are proficient enough to support life and possibly some sort of intelligent species, so how come no one has visited earth? This became known as The Fermi Paradox, which came from his surname and two Greek words, para meaning contrary and Doxa meaning opinion, about a 100 years ago. (Webb 2002) A paradox arises when you set undisputable evidence and then a certain conclusion contradicts the idea. For example, Fermi realized that extra-terrestrials have had a large amount of time to appear
...hes. In Alice and Quantumland, the principles or concepts of quantum mechanics are compared with the macro world; one can find great similarities and even greater dissimilarities between the world wherein electrons rule, and the world wherein human beings live. The author, Robert Gilmore, creates an allegory based off the principles of quantum mechanics using the original story of Alice in Wonderland. Through Alice’s adventure in Quantumland she comes across some ideas or features that contradict real world ideas. These ideas are the following: Electrons have no distinguishing spin, the Pauli Exclusion Principle, Superposition, Heisenberg Uncertainty Principle, and . All of these features are comprised essentially of the same universal concept--that the quantum world does not require definity whereas the macro world uses it as a pillar of society and civilization.
In the 1920s the new quantum and relativity theories were engaging the attentions of science. That mass was equivalent to energy and that matter could be both wavelike and corpuscular carried implications seen only dimly at that time. Oppenheimer's early research was devoted in particular to energy processes of subatomic particles, including electrons, positrons, and cosmic rays. Since quantum theory had been proposed only a few years before, the university post provided him an excellent opportunity to devote his entire career to the exploration and development of its full significance. In addition, he trained a whole generation of U.S. physicists, who were greatly affected by his qualities of leadership and intellectual independence.

This Essay is meant to shed light on a complex subject, quantum entanglement. Now, quantum entanglement is a part of much more complex subjects, such as classical mechanics, quantum theory, and quantum mechanics; these subjects will not be covered. The idea of quantum entanglement will be explained: What it is and when does it happen. After a little understanding of Entanglement, a discussion will follow on what it means for us from a technological standpoint and what can we accomplish in the near future. Pushing that idea further into the future looking at bigger possibilities in transportation, and what potential liabilities and moral dilemmas could ensue. It is my belief that quantum entanglement could accomplish many great things, but could
Over a 1950 summer lunch at the Los Alamos National Laboratory, the great physicist Enrico Fermi asked his colleagues an unexpected question – “Don’t you ever wonder where everybody is?” Laughter went around the table as everyone immediately knew that he was talking about extraterrestrial intelligence [1]. If life arises fairly commonly, as Fermi believed, it follows that there should be advanced civilizations with the desire to visit and colonize Earth close enough to do so. However, there is no incontrovertible evidence of aliens on Earth, either now or in the past. This is called the Fermi Paradox. The lack of observational evidence for extraterrestrial intelligence is known as the ‘Great Silence.’[13]
Dmitri Mendeleev was one of the most famous modern-day scientists of all time who contributed greatly to the world’s fields of science, technology, and politics. He helped modernize the world and set it farther ahead into the future. Mendeleev also made studying chemistry easier, by creating a table with the elements and the atomic weights of them put in order by their properties.
Of the many counter intuitive quirks of quantum mechanics, the strangest quirk is perhaps the notion of quantum entanglement. Very roughly, quantum entanglement a phenomenon where the state of a large system cannot be described by the state of the smaller systems that compose it. On the standard metaphysical interpretation of quantum entanglement, this is taken to show that there exists emergent properties1. If this standard interpretation is correct, it seems that physics paints a far different picture of the world then commonsense leads one to believe.
Theoretical physicists Albert Einstein and Enrico Fermi were two key scientist throughout “The Manhattan Project”. It started after Albert Einstein successfully escaped
Richard P. Feynman was born in 1918 in Brooklyn; in 1942 he received his Ph.D. from Princeton. Already displaying his brilliance, Feynman played an important role in the development of the atomic bomb through his work in the Manhattan Project. In 1945 he became a physics teacher at Cornell University, and in 1950 he became a professor at the California Institute of Technology. He, along with Sin-Itero and Julian Schwinger, received the Nobel Prize in Physics in 1965 for his work in the field of quantum electrodynamics.
As is evident by the vast number of cinematic interpretations of possible events, communication with extraterrestrial life has been a fascination of humans for years. The complex that grew to be known as the Fermi Paradox only exacerbated this fascination, as it accented the unlikeliness that if there is life elsewhere in our own galaxy, we have yet to know anything about it (https://www.seti.org/seti-institute/project/details/fermi-paradox (Links to an external site.)Links to an external site.). This desire for contact has grown and culminated in the largest deliberate broadcast with the intent of establishing contact with interstellar life: the Arecibo Message (https://www.space.com/20984-arecibo-observatory.html).
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.
Werner Heisenberg was the first to realize that certain pairs of measurements have an intrinsic uncertainty associated with them. For instance, if you have a very good idea of where something is located, then, to a certain degree, you must have a poor idea of how fast it is moving or in what direction. We don't notice this in everyday life because any inherent uncertainty from Heisenberg's principle is well within the acceptable accuracy we desire. For example, you may see a parked car and think you know exactly where it is and exactly how fast it is moving. But would you really know those things exactly? If you were to measure the position of the car to an accuracy of a billionth of a billionth of a centimeter, you would be trying to measure the positions of the individual atoms which make up the car, and those atoms would be jiggling around just because the temperature of the car was above absolute zero!
1905, and published four of his major research papers, including his Theory of Special Relativity. This theory would later contribute to other ideas and discoveries, one of which would be the Mass-Energy Equivalence. Einstein was awarded a Nobel Prize for physics in 1921, and later immigrated to the United States in 1933, where he began his professorship at the Instit...
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...
