In 1897, a little more the one hundred years ago, the electron was first discovered. With the discovery of the electron came the discovery of the neutron roughly thirty-five years later. These two discoveries were very important to the furthering of quantum mechanics. Without these discoveries, quantum mechanics would not have become something so important. Quantum mechanics is the branch of mechanics that deals with the mathematical description of the motion and interaction of subatomic particles. "Atoms and photons are intrinsically quantum mechanical, so it 's no surprise if they behave in quantum mechanical ways.”
Quantum mechanics is a subject that is not easily understood. Since it deals with the properties of subatomic particles, or very small things, it is nearly

Going back to whether atomic particles behave like particles of waves, light is the greatest example of showing how they behave like a wave. Wavelengths come in in all shapes and sizes ranging from electrons with wavelengths a trillionth of a meter long to radio waves that can reach up to miles long. The most specific point quantum mechanics brings up regarding light and wavelengths is their ability to go through gaps, for example a doorway. You can see hints of light passing through the cracks and edges of a doorway because the wavelength like properties are easily bent and can move however they want.
Another common life application of quantum mechanics is the ability to use mobile phones to communicate with people all over the world. Because scientists were able to recognize that these waves were able to carry the signal to produce communication from wherever, lives have become easier. If quantum mechanics wasn’t studied as much as it is, communication would be very difficult, making life extremely hard. The use of communication is the biggest impact studying quantum mechanics has had on our
physics. The work of Ernest Rutherford, H. G. J. Moseley, and Niels Bohr on atomic
The novel, Alice and Quantum Land, by Robert Gilmore is an adventure in the Quantum universe. Alice, a normal teenage girl, goes through quantum land and understands what quantum is and how it works. The quantum world is a difficult one to understand, as its nature is one of complex states of being, natures, principles, notions, and the like. When these principles or concepts 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. In Alice in Quantumland, author Robert Gilmore converts the original tale of Alice in Wonderland from a world of anthropomorphic creatures into the minute world of quantum mechanics, and attempts to ease the reader into this confusing world through a series of analogies (which comprise an allegory) about the principles of quantum mechanics. Through Alice’s adventure 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 Interference and Wave Particle Duality.
The study of neurobiology has long involved the actions and interactions among neurons and their synapses. Changes in concentrations of various ions carry impulses to and from the central nervous system and are responsible for all the information processed by the nervous system as a whole. This has been the prominent theory for many years, but, now, there is a new one to be reckoned with; the Quantum Brain Theory (QBT). Like many new theories, the QBT has merits and flaws. Many people are wholeheartedly sold on it; however, this vigor might be uncalled for. Nevertheless, this could prove to be a valid and surprisingly accurate theory of brain function.
The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs.
Light is both part particle and part wave. Light is “the electromagnetic radiation that may be perceived by the human eye”. It consists of photons, which are massless bundles of concentrated electromagnetic energy. Light’s lower frequency is red, and the higher frequency is blue. Like sound, light has frequencies humans can’t detect. Ultraviolet light is at a frequency higher than violet, and infrared is at the frequency lower than the red of visible light. We get UV (ultraviolet) rays from the sun, and infrared is used in night vision to see better.
Physics can be found in all aspects of our lives and the world around us including the activities in which we find the most enjoyment. They may not be noticeable to the naked eye or even to our senses but they are there and when we become familiar with the concepts of physics then we began to ‘see’ physics everywhere.
The theory of quantum mechanics has divided the atom into a number of fundamental sub-atomic particles. Although the physicist has shown that the atom is not a solid indivisible object, he has not been able to find a particle which does possess those qualities. Talk of particles, though, is misleading because the word suggests a material object. This is not the intention for the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way.
In 1801 Thomas Young provided some very strong evidence to support the wave nature of light, he placed a monochromatic light in front of a screen with two slits cut into it, and observed an interference pattern, only possible if light was a wave. In 1965 Richard Feynman came up with a thought-experiment that was similar to Young’s experiment. In Feynman’s double-slit experiment, a chosen material is fired at a wall which has two small slits that can be opened and closed at will – some of the material gets blocked and some passes through the slits, depending on which ones are open.
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.
I feel personally that the discovery of the atom was an important discovery for the world. With the discovery we are now able to answer questions we never even thought to ask. We are also answering questions some people asked long ago. We can now use our vast knowledge of the atom to measure the stars and be able to tell you what the stars are made of. The atomic discovery also helped us find our periodic table of elements. The periodic table of elements is a huge scientific chart that shows important facts with the help of its formation. There was a lot of constant scientific research that went into making the periodic table of elements and what it is today.
Some physical entities such as light can display some characteristics of both particles and waves. Before the early 20th century, scientists believed that light was in the form of an electromagnetic wave. It wasn’t until the 20th century onwards that scientists found that light has properties of waves and particles. Scientists discovered different properties of light through experimentation and allowed them to determine that light actually has a wave-particle duality.
There are still limitations in classical cryptography, it is purely mathematical and information cannot be separated from its physical representation. In Classical physics, we use binary form to store and process the data. In the 1980s, C.Bennet, P.Benioff, R.Feynman and others observed that new and very powerful ways of information processing are possible with quantum mechanical systems. This gave birth to the concept of quantum computing.
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.
In conclusion the only way the everyday consumer could technically have a quantum computer is by owning 14,000 grams of gold. In reality, the commercial quantum computer will be a coming in a lifetime. Currently, the quantum computer can only calculate elementary math and nothing more. We could use the qubit to build softwares that could theoretically process
I believe that the growing role of mathematics, science and technology in modern life demands that we, for our active participation in society, personal satisfaction and our working development we should not only be able to read and write but also, have the skills and knowledge in these areas. Before doing the readings I thought that being scientific and mathematic literal was to be able to solve math and science problems. My opinion changed drastically after reading each article and book on my reference list. Now I believe that it’s not only to be able to solve problems, but that being Scientific and Mathematic literal is to be able to communicate with others in our or in different areas of study, to think on the nature of a subject and work
