To add to the following answer, the wave formulation of quantum mechanics states that the expectation value of the position operator yields a position probability distribution which says, "this is the area where the particle is." Which is typically over all space. Once the position of the particle is measured, the wave function corresponding to the particle then instantly collapses and the particle is only at that position and therefore cannot be anywhere else. That fact then leads to Heisenberg's Uncertainty Principle, which is a whole other topic for discussion.
absolutely, in some cases a single object can even be in infinitely many places at the same time. Look into Feynmann diagrams and path integrals.-----This is an incorrect interpretation of Feynmann diagrams, which actually say the particle is everywhere until it's position is measured. Once it is measured it cannot be anywhere else. No single particle can be simultaneously measured to be in two separate locations. That violates the principles of QM.
No. Quantum mechanics gives the probability of an object's location- so it can have some small possibility of being at infinitely many places at the same time but never definitely at more than one place at the same time. This may be a fine distinction but it restricts a large number of ridiculous phenomena.

∙ 11y agoIt is very difficult to know exactly where a subatomic particle is, at a given time; this difficulty is expressed by the Heisenberg Uncertainty Principle. And under some circumstances, a photon does appear to be in two places at once, because there are two places where it is equally likely to be. Subatomic particles do not have definite locations of the kind that we are accustomed to in the macroscopic world which we inhabit. They are governed by quantum mechanics, which can produce very odd results.

Discoveries and inventions in the field of physics?
Some of the most important discoveries and inventions in physics include quantum foam, all objects fall at the same speed without gravity, all matter is energy. Those studying physics are discovering new things all the time.
What is the development in the field of physics in 1900?
The year 1900 was a great year for physics. Up to that time, scientists believed that all that needed to be discovered had already been discovered. German physicist Max Planck was given the task to solve a problem in relation to black body radiation. On the basis of the theories in physics at that time, Planck could not solve this problem. Finally, he got the idea of assuming that energy was discrete in nature, that waves consisted of particles and that their energies were proportional to the frequency of the waves. Surprisingly, this solved all his problems. It made his equations possible. This gave rise to a completely different notion about many things in nature. This new theory was called the quantum theory. As it turned out to be, the quantum theory became very useful in describing many phenomena which would have otherwise been impossible to explain (for example the photoelectric effect) This was such a great discovery in the history of physics that physics before 1900 was referred to as 'classical physics' and physics after 1900 'modern physics' For establishing the quantum theory, Max Planck was awarded the Nobel prize in physics in 1918.
What is the difference between classical physics and quantum physics?
Classical Physics is based on Newtonian Physics, which is accurate for macroscopic practical daily life scenarios. The laws of physics are based on those created by Isacc Newton in the 15th and 16th century. In 1905, Albert Einstein founded the Theory of Special Relativity which proved that Newton's laws of physics were not complete and were actually wrong. It also proved that the speed of light was a universal constant and nothing could travel faster. Newton's laws were nearly exact in our normal lives. But when you are dealing with extremely small scale problems such as with atoms or when you dealing with great velocities, the results seem to disobey Newton's predictions. The universe behaves and was found to be much different than it first appeared! Einsteins new equations were basically a "polished" version of Newton's equations, which applies to both low and high speeds. This is how quantum physics was founded and much of it is based on these new equations! It mostly deals with high speeds or atomic scales. Think of quantum mechanics as the "polished" version of classical physics, it tells the whole story of physics and not just an estimate. For instance, you may not notice it when walking down a street but time slows down by an astronomically small amount and your body contracts by a very small amount, relative to the outside universe. It becomes much more apparent at extremely high speeds. As unnoticeable as it is, the effects exist everywhere. --- In classic physics everything is deterministic; in quantum physics nothing is.
Is Murphy's Law explained by quantum physics' fourth dimension connection?
No, it is not. Murphy's Law states that if something can go wrong, it will. (There are variants and corollaries.) And if by the fourth dimension connection in quantum physics you mean the dimension of time in spacetime, things happen there according to probability and statistics, or get caught up in uncertainty, à la Schrödinger. The consequences of these things (the quantum mechanical one) with regard to Murphy include the idea that sometimes something must happen, and at other times it can or might happen. And if the latter is true, it might happen or might not happen. Murphy says if it is possible (for something to go wrong), it will happen. Additionally, in the world of quantum mechanics there is a question of when things will happen, and time is relative. Time is not relative to Murphy except in the version of Murphy's law which says that if something can go wrong, it will go wrong, and at the worst possible time and having the worst consequences. That's pretty specific and not something that is timed with a clock. You can't get that kind of specificity in quantum mechanics because of relativity, if for no other reason.
What is physics is all about?
Physics is the study of matter and its motion. (Along with the study of space and time.)
What branches of mathematics help time scientists?
Physics, particularly quantum physics (which is essentially mathematics).
In the quantum world what is it called when there is a quantum change?
a quantum fluctuation Quantum Physics is the physics of the atom and the particles that make up atoms, and they behave according to a different set of rules than large objects like people. So a quantum change could be any sort of change at the atomic and subatomic level, like an electron's direction of spin, its velocity, or its probability of being in a certain location. Electrons are in many places at the same time, spinning different ways at different speeds. It's only when we go to measure one of these properties that it "snaps" into one of its possible locations.
Why will gravity alter the path of light if light itself does not have any mass?
Quantum physics determined that light acts like an electromagnetic wave and a particle at the same time.
What has the author L S Schulman written?
L. S. Schulman has written: 'Time's arrows and quantum measurement' -- subject(s): Thermodynamics, Mathematical physics, Quantum theory, Time measurements, Quantum statistics, Cosmology
Why quantum physics is beautiful?
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 eyes. In my opinion, i think quantum physics is beautiful in that way.
Can you be in 3 places at the same time?
No. The Laws of Physics will back me up on that.Putting science aside, one could say that they were in the shopping mall as well as in Edmonton while at the same time being in Canada all at the same time. But I don't think that would work if it was three different places at the same time.
Does quantum theory deny strict determinism?
Yes - a deterministic theory means that given initial conditions, it yields a precise answer for future time. This does not happen in quantum physics. Read the Feynman lectures on physics volume 3 for more information.
What are the subdivisions of physics and its description?
Mainly:Mechanics (Newtonian & relativistic): - mater - time - space;Molecular physics & thermodynamics: - physics of thermal movement;Electromagnetism: - physics of E,H - field;Wave motion: - physics of sound, light, ..., solitons (tsunami);Quantum physics: physics of micro-world;High energy physics.
Is quantum physics more complex than software design?
Absolutely. Quantum Physics is all about matter and energy a gigantic field that still remains unsolved. This is very complex stuff! Even Einstein said so (E=MC2). Think of Quantum Physics as a large metal ball that is damaged every time something new about Quantum Physics is discovered. When Einstein discovered E=MC2, he merely scratched the surface of Quantum Physics. Everyone knows how complex his theory is, and if that's only a scratch of Quantum Physics, imagine how hard it would be to damage the rest. At this moment, Quantum Physics is virtually unsolvable. Software Design, on the other hand, is easy to solve. Software Design addresses a know specific problem. If your really good at Software Design, then designing a software, is a straight forward approach. Compare understanding Matter and Energy (and the Universe of Qunatum Physics) to making Microsoft Word or another Software. There's a COLOSSAL DIFFERENCE! I Hope this has answered your question.
Why you need quantum or modern physics while classical physics existed already?
Classical physics was based upon how the things we deal with every day move when we deal with them in everyday situations. As we started to discover new things (protons, electrons, redshift, etc) classical physics failed to completely explain what we observed. Modern physics explained time-and-space related quandries while quantum physics explained wave-and-particle dualities.
What makes angels fly?
Angel dust, otherwise known as PCP.If you study quantum physics, many of the descriptions in the Bible of what angels supposedly can do like fly, be in two places or many places at once, and that they are being of light gives a hint to what and where they exist. Angels are light, made up of non-matter. This is why we can not see them. Study quantum physics and you will find that an Angel, if made of nothing but light can be in New York City and California at the same time. Angels fly because they move at the speed of light, because they are light. They travel at 186,000 miles per second. They think of where they want to go and poof, they are there.
