What is the basic principle of quantum physics?
The basic principle of Quantum Physics is uncertainty. This is at the core of the Uncertainty Principle, Superposition of States, and Quantum Tunneling and Entanglement.

The principle quantum number has the symbol n. It tells which energy level an electron is in. The values include one and beyond. The lower the number, the closer the energy level is to the atom's nucleus. Multiple electrons can be in the same energy level. Also, n 2 is the total number of orbitals …that can exist within an energy level n. For example, level 1 has 1 orbital (s=1). Level 2 has 4 orbitals (s=1 + p=3). Level 3 has 9 orbitals (s=1 + p=3 + d=5). Level 4 has 16 orbitals (s=1 + p=3 + d=5 + f=7). Each letter, s, p, d, and f stands for a type of sublevel that contains a certain number of orbitals.

Quantum physics is the study of the motion of particles, specifically the study of the behavior of subatomic particles such as photons, quarks, neutrons, leptons and about 20 others. These particles make up the basic atom and are responsible for the interactions of atoms and the basic properties of… matter and energy. Quantum physics is the area of physics that focus on things that are on the atomic scale. Quantum physics, or quantum mechanics, explains why atoms, electrons, etc. act the way they do specifically on that really small scale. ( Full Answer )
Probably Werner Heisenberg, because he came up with the uncertainty principle. The uncertainty principle (look further into this) essentially suggested that the way particles--particularly electrons--interact in the physical world is all based on probability. This but quantum mechanics away form all… of the other sciences at that time. Thus making Heisenberg be the father, because he came up with the Uncertainty Principle. ( Full Answer )
Planck formulated an equation for energy quanta, which is quantized into E=hf (where E is energy, h is Planck's constant: 6.626x10 -27 , and f is frequency) to obtain his own exact radiation formula. This also happened to disprove the theory of the Ultraviolet Catastrophe, which is where classica…l physics failed. ( Full Answer )
Really, quantum physics has been developed gradually, and by a large number of people. I don't think a single person can be credited of having "invented" or "discovered" it.
Quantum physics are the laws used to govern the goings on in the realm of the micro because Newtonian physics (the old physics) do not apply to this realm. Quantum mechanics are based on statistics and group behavior because it can be predicted how many particles in a group will behave a certain way… but it is impossible, at least for now, to predict which particles in a group will behave that way.

Yes, it is a science. It is a study of the individual, microscopic units of matter and beyond such as the atoms and it's parts and parts of the atom's parts etc. (I'm sorry if it's confusing). It's very complicated and you should learn the simplest parts about it around grade 7. This may sound stran…ge coming from me. I hope this answer helps. ( Full Answer )

Quantum maechanics is particulary used when we deal with submicroscopic systems, example suatomic particles. So when you wish to examine the approximate motion of an electron, QM can be of great help. But exact analysis of electronic trajectory is not possible.(Heisenberg's UP)
Basic principles are ideologies that guide a school of thought or for that matter an entire institution.These are laid down by thinkers or the heads of an institution.It can be called a charter that helps anything to work with the help of the bylaws that are set.
Since I LOVE physics, astronomy, genes, chemistry, and science in general. I especially like quantum physics. However, I'm just 12 years old and I go to this separate school every Saturday and ask my Algebra 2 teacher about quantum physics since she is a high school. I ask her about the M-theory, wa…ve-functions, super-string theory, gravitons, and others. Sometimes she clears things up for me. Apart from that, I read, read, and read. Read. I took physics class for my age at this one summer thing and is was SO SO SO BORING. The stuff I'm reading is college level quantum physics, so unless you are college age i suggest you read, read, and read some more. Hope this helps. ( Full Answer )
In order to explain black body radiation Max Planck had tointroduce the idea that electromagnetic radiation was emitted indiscrete packets or "quanta" rather than continuous waves. Eachquantum had a fixed energy given by E = hf where h is a constantand f is the frequency.
During the nineteenth century the main theory in physics was still Newtonian Mechanics. With the advances in electricity, magnetism and the studies about light, it was clear that the theory had its limitations. The limitations appeared in the limits of the too small (atomic size) or the too fast (li…ght speed ). The study of the small limit took a long path and it has several contributors. It started in the beginning of the 1900s and laid the foundation of the modern quantum and particle physics. ( Full Answer )
What are the basic physical principles of a laser system? What about laser in dentistry?
Its based upon mobile phase solvent that moves along a solid phase. It separates components of a mixture based on how quickly different molecules dissolves.
spin is the symmetry of something, if it has a spin of 1, then you need to rotate the thing 1 full circle for it to look the same as when you didn't rotate it. if it has a spin of 1/2, then you need to rotate it 1/2 of a circle. it is actually possible for something to have a spin of 2 (2 full circl…es) or higher.

The theory of quantum mechanics is mostly based on the idea that all particles are describe by wave functions. In other words, particles are not simply items located at a specific point in space. Instead they can only be described by probability distributions, we can only say that a particle has s…ome probability of being found at some point in space, and that the particles may be found ANYWHERE in the universe (though with varying probability). The basic principles of quantum theory are Schrodinger's equation (which describes the evolution of a particle's probability amplitude with time), Heisenberg's uncertainty principle, (which denies the ability of science to ascribe a definite trajectory of a particle), and in some texts, the "canonical commutation relation" is presented as a fundamental principle of QM.

It's beautiful, because we can think of it and not see. We never saw and atom with our eyes, but with all of the equations that was invented by brilliant people, we can see through that. We can never use observation with quantum physics(except for experiments). For the first time, we don't use our e…yes. In my opinion, i think quantum physics is beautiful in that way. ( Full Answer )
I think it can, to collapse the wave duality function of an electron, a conscious observer must make a measurement, or observation. Nobody knows what the world looks like when nobody is looking, but who collapsed the wave function when we weren't here? That leads to another question, does God count …as a conscious observer? I do believe in a God, as I am a protestant, but I think this is an interesting topic that should not be ignored. Note: If you ever hear about the "God particle" - it has nothing to do with God, but scientists hope that it will explain why things actually have mass. Hope that helps. ( Full Answer )

Nanotechnology is the understanding and control of matter at the realm of 1 to 100 nanometers. (For reference, a piece of paper is about 100,000 nanometers thick.) At the nanoscale, matter functions differently from both the individual atomic and macroscopic scales, so some unique properties are ava…ilable for use in the field. Nanotechnology is a natural end-result of scientific development and our ability to understand and manipulate matter at smaller and smaller levels. Just as computers have gone from bulky, room-filling monstrosities to handheld computers, such reductions in size will continue until we reach fundamental physical limits. Quantum mechanics or quantum physics are just the study of subatomic sized objects. ( Full Answer )
It most certainly is! It has to do with things that are very small. Atomic [or Nuclear] Physics is essentially the study of the quantum world.
Partial of it does. I think your question is leaning towards wavefunction. It is pretty hard to get but with study you will eventually get it. Since I'm twelve I got the whole day. If i explain it here is would be hard to understand. On google or something else, look up the double slit experiment. I…t was an experiment created by Thomas Young, that was meant to explain if light was a stream of particles, or waves(today it's a photon a combination of both). It turns out that the the human observation collapse the wavefunction of subatomic particles. All I can tell you is this, wavefunction is basically the chance of the position and momentum of subatomic particles. You can't have a definite answer to both of them. You either know more about the position and less about the momentum and vise versa. Hope this helps. ( Full Answer )
Quantum Mechanics and Quantum Physics apply to so many aspects of science that, despite how radical it is, its still accepted. This is because almost all of astronomical physics and other areas of science would just collapse! For example, black holes appear to radiate energy, but a black hole (by de…finition) does not give out anything. Therefore, Quantum Mechanics says that there are certain fluctuations on the edge of the black hole's event horizon, where two particles (a negatively charged one and a positively charged one, since energy cannot be created out of nothing) spontaneously appear and immediately cancel each other out, and disappear. However, when on a black hole's event horizon, one particle is sucked in before they destroy eachother. Then, the particle leaves and survives! The same kind of aspect can be applied to discover black hole evaporation, where a singularity slowly weathers away. In short, Quantum Mechanics is extremely important to modern day physics.

Without quantum physics LASERS would have not been discovered and the digital age would be corrupted.

Quantum physics is a branch of science that deals with discrete, indivisible units of energy called quanta as described by the Quantum Theory. There are five main ideas represented in Quantum Theory: . Energy is not continuous, but comes in small but discrete units. . The elementary particles b…ehave both like particles and like waves. . The movement of these particles is inherently random. . It is physically impossible to know both the position and the momentum of a particle at the same time. The more precisely one is known, the less precise the measurement of the other is. . The atomic world is nothing like the world we live in. While at a glance this may seem like just another strange theory, it contains many clues as to the fundamental nature of the universe and is more important then even relativity in the grand scheme of things (if any one thing at that level could be said to be more important then anything else). Furthermore, it describes the nature of the universe as being much different then the world we see. As Niels Bohr said, "Anyone who is not shocked by quantum theory has not understood it." I agree with him on that quote. Always remember this, no one in this world fully understands quantum mechanics or quantum physics. ( Full Answer )
A particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms of diameter , fine particles cover a range between 100 and 2500 nanometer , while ultrafine particles, on the other hand, are sized be…tween 1 and 100 nanometers. Similar to ultrafine particles, nanoparticles are sized between 1 and 100 nanometers. ( Full Answer )
I am around ten and I'm a geek with quantum physics. As of right now, the key factors with quantum physics are the equations and it is not an opinion. The second most important factors is logic. We can't see subatomic particles, but we can see it through mathematics. Those are the key aspects of qua…ntum physics. Good Answer geek: The key aspect of quantum physics is quaternions. Quantum physics is four dimensional physics. Prior physics involved two dimensions, mostly complex mathematics z=a + bi, this could be called parallel physics. Quantum physics involves quaternions a four dimensional physics q= a =bi +cj +dk, this is non parallel or non-commutative physics. For example Z1Z2 = Z2Z1 for two dimensional physics, but Q1Q2 does not equal Q2Q1 for quaternion Physics. This quaternion aspect of Quantum physics is THE key. Another aspect of Quantum Physics that is overlooked is the free space impedance z= 375 Ohms. Not much attention is paid to z but it is a quantum constant, z= W/Q where W is the quantum magnetic charge in Webers and Q is the quantum electric charge in Coulombs. W and Q are make up Planck's Constant h=WQ. W= 500 atto Webers and Q=4/3 atto Coulombs. h=zQ^2. z is the "Aether" Maxwell postulated as necessary to transport electromagnetic waves and M&M did not find. The Fine Structure Constant Alpha = 1/2 (e/Q)^2 = 7.2E-3 where 'e' is the electric charge and Q the quantum charge. ( Full Answer )
No. Quantum Physics allows us to understand our universe.The nature of electromagnetic waves and particles.
In theoretical physics, a singlet usually refers to a one-dimensional representation (e.g. a particle with vanishing spin). It may also refer to two or more particles prepared in a correlated state, such that the total angular momentum of the state is zero. Singlets frequently occur in atomic phys…ics as one of the two ways in which the spin of two electrons can be combined; the other being a triplet. A single electron has spin 1/2, and transforms as a doublet, that is, as the fundamental representation of the rotation group SU(2). The product of two doublet representations can be decomposed into the sum of the adjoint representation (the triplet) and the trivial representation, the singlet. More prosaically, a pair of electron spins can be combined to form a state of total spin 1 and a state of spin 0. The singlet state formed from a pair of electrons has many peculiar properties, and plays a fundamental role in the EPR paradox and quantum entanglement. In Dirac notation this EPR state is usually represented as:. ( Full Answer )
There is no quantum physics of a moose. Quantum physics is a type of theoretical physics, and its laws do not apply to physical objects
Knowledge gives people power. By understanding the basic principlesof physics and technology, you'll be more aware of how the worldaround you works, you'll have more confidence, and a greater senseof understanding in terms of how life actually functions.
They apply to macroscopic scales that do not influenece the physical world around us, so it only applies to things the newtonian physics don't cover.
In physics, quantum is a discrete natural unit, or packet, of energy, charge, angular momentum, or other physical property.
Mathematically, it's based upon analysis (calculus, differential equations, etc.) as are most fields of physics, but what really sets quantum apart from other physics fields is it's fundamental mathematical dependence on probability, linear algebra, and group theory. It's conceptually based on un…certainty, probability, and discreteness (as opposed to absolute and continuous). ( Full Answer )
To a certain extent, yes. A good example is in the Schroeder's cat theory. The theory is: that Schrodinger (a notable physicist.) would have a box, which held a cat, hooked up to a mechanism that contained a radioactive atom with a 50% chance of decaying within 1 hour. If the atom decayed, it would …then set off the mechanism, killing the cat. If it didn't decay, however, the cat lived to be shoved in the box another day. The point was that, until it is recorded by a person that observes the atoms, that the radioactive atom exists in the decayed and undecayed superpositions, so does the cat? (In the superpositions dead and alive.) This would then agree with the measurement problem, which states that anything is not in a definite state until observed. However, this would then mean that nothing definitely exists unless humanity itself discovers it, which contradicts rational thinking. So there you go, proof of there being probability in quantum physics, expanded into an unnecessarily long answer. I'm sorry if you log off with more info then you were looking for. ( Full Answer )
Yes many but I would advise "How to teach quantum mechanics to you dog" By Chad Orzel
Well... God, if you're into that sort of thing. I suspect the answer you're looking for is Max Planck, though. A great number of people made early contributions to the field, but Planck was the first one to actually say "hey, look, it's all quantized."
Parity in quantum mechanics is equivalent to the macroscopicconcepts of handedness or chirality . Parity isconserved by the electromagnetic force, strong force, andgravitational force; but it is violated by the weak force.
Quantum physics looks at the world of physics in terms of 'packages', or particles. Ie, gravity acts the way it does do to the behavior of the 'gravitron', which is a quantized measurement. The branch of physics that uses quantum theory to describe and predict the properties of a physical system.
Quantum physics does not affect reality in any way, rather it is a group of hypotheses that has been advanced to try to explain how the physical world works and why it works in that manner.
because the scientist who discovered quantum number his first letter of name is k.the name of scientist i am missing.
No one knows : its a mathematical construct whose only claim to fame is that it matches reality (as we know it).
Which GCSE option would be most useful if you wanted to go into physics such as quantum mechanics Computing which is basically programming or Astronomy which has little bits of basic astrophysics?
I would recommend that, for Technology you choose either Electronics or Systems and Control. I wouldn't recommend ICT or IT because they are all about learning how to use Microsoft Office and other software that will most likely become outdated before you leave university. Languages, Humanities and …Arts wouldn't have a relevant choice so pick subjects that you are likely to get a high grade in. For Natural Sciences pick Physics and either Chemistry or Astronomy. Choosing Physics is very important because for A-Level the best combination is Maths, Further Maths, Physics and the most relevant forth option that your chosen sixth form has to offer. This is because the most prestigious universities such as Oxford and Cambridge require you to have these A-levels to do Science related degrees such as those in your question. I wish you the best of luck in whichever GCSEs you choose in the end. Katie ( Full Answer )
A principle quantum number is always symbolized by a lowercase letter "n." The function of a principle quantum number is to show positive integer values in an equation.
I have no idea what you mean by "the basic structure of quantum mechanics". Interpreting it in the most reasonable way I can, I guess I'd say "mathematics." The fundamental basis of QM is the subject of regular conferences. The ruling paradigm is the Niels Bohr/Heisenberg 'Copenhagen interpretat…ion'. Some years ago Max Tegmark found much disagreement. A 2011 conference (Austria) than also ran a poll. The most popular was still 'Copenhagen' but with less that 30% of the votes. 28% thought Einstein was wrong, and the rest were split between 5 other possible bases. i.e. there is now even less agreement and even more confusion (QM is also still not compatible with Relativity). The real solution is that wavelength changes on interaction with the quantum particles of a moving detector (lens) medium, to travel at the local c/n. (n=refractive index, locl means the state of motion of the observer). This understanding (DFM) is likely to replace the others over the next 20 years, which is quite fast in cosmic terms.

What sort of proof do you want? It has certainly been found that modern physics (on the one hand, quantum physics, on the other hand, the theory of relativity) provides a more precise description of the Universe than classical physics. .
Creates security keys using procedures and protocols. Creates security through the use of single-photon light pulses. Is based on the law that a photon's state will change if observed.
Actually they are the same. It deals with physical phenomena at a microscopic scale, like how electrons can behave and move about. The interaction between particles is very different on what we do in physical world.
Quantum physics studies that realm of our Universe where quantumeffects predominate. This is (basically) at the sub-atomic level,and it's here where the phyics laws we are used to, simply don'tapply. For example: 1) We have to give up the notion that an object -- such as anelectron -- has an exact p…ostion and momentum. Instead, we can onlydiscuss the probability of an object being within a certain spaceat a certain time, or having a certain momentum. And it is NOT thecase where we humans lack the ability to determine position ormomentum -- the REALITY is that, in quantum physics, thesequantities are fundamentally unknowable. 2) In addition, any attempt to more precisely measure one aspect ofa quantum particle -- say, its position -- automatically makesanother aspect more unknowable. In this case, the momentum becomesmore imprecise. Again, this isn't because we human aren't cleverenough to do these measurements simultaneously, this is afundamental fact of our Universe. 3) Certain aspects of an object come in discrete chunks, such thatthe object can have one of quantity, or two of a quantity, but canNOT have 1.5 of a quantity. For example, a spinning ice skater can have a certain amount ofangular momentum, and can then slow down to half that amount -- orthree-quarters, or two-fifths, or .764 of that amount. An electron,on the other hand, can ONLY have a specific level of angularmomentum -- not half that amount, not three-quarters, anddefinitely not .764 of that amount. Our Universe does not allow itto happen. 4) In quantum physics, it is a meaningless question to ask what ISthe value of certain aspects of a quantum particle prior tomeasuring that value. For example, if you send photons or electronstowards a pair of slits, you will get an interference pattern onthe detector behind the slits, even if you send the particlestowards the slits one at a time. However, if you attempt todetermine which of the two slits the individual particle wentthrough prior to reaching the detector, the interference patternvanishes. Experiments have shown that the any attempt to determineposition prior to measurement will alter the final result. 5) Even weirder sub-set of (4): experiments have shown that justmaking a measurement of positon POSSIBLE will also change the finalresult -- even if you don't make the measurement! In the doubleslit experiment noted above, the interference pattern vanishes whenthe slits are set up to make it possible to determine which oneslit the particle went through, even if the experimenter didn't doso! It's as if the particles are saying, "I know what you're tryingto do, and I'm not going to let you do that." It's been said, "If you're not bothered by quantum physics, thenyou don't understand it." I hope this BRIEF OVERVIEW of some of itsconsequences leaves you bothered. ( Full Answer )
