Would you explain me, what is quantum physics in plain and simple english for non Einsteins??

Answer 1

Quantam physics(or quantum mechanics), is probably the most bizarre aspect of physics. Quantum mechanics states that an electron doesn't necessarily exist in a definate place but has a chance of being found there. The area where it
"is" is simply the area that the electron has the highest chance of existing. Okay, that's a little complicated. How about this... When a proton is not being detected(looked at, touched, smelled, whatever) the proton is in a sort of limbo between where it actually is. It has a high chance of existing in one definate place, but this isn't necessarily where it will be. It could be found halfway across the universe or three inches from where you thought it was. Before it is detected, it can be anywhere. But, when it is finally detected, it makes a quick decision (not literally) and places itself in one of it's possible locations(the higher the probability, the more likely you will find it there). This set of probabilities is called it's wave function. Now, this may seem stupid and absurd(Einstein though so too), but it's been confirmed experimentally. I hope this helped.

Okay, I apologize, that's only one aspect of quantum physics, but it's the one I know the most about.

Answer 2

In physics, quantum mechanics is the study of the relationship between energy quanta (radiation) and matter, in particular that between valence shell electrons and photons. Quantum mechanics is a fundamental and necessary branch of physics with wide applications in both experimental and theoretical physics. Quantum theory generalizes all classical theories, including mechanics, electromagnetism (except general relativity), and provides accurate descriptions for many previously unexplained phenomena such as black body radiation and stable electron orbits.The effects of quantum mechanics are typically not observable on macroscopic scales, but become evident at the atomic and subatomic level.

Answer 4

Physics is the science that describes fundamental aspects of the universe. Physics describes the motion of planets and explains things like orbits and gravitational attraction.

Quantum physics is physics for things at the very small "quantum" level. It turns out that things act surprisingly different at the quantum level. Single primary particles move and interact very differently than the average effect we get working with groups of matter containing millions of such particles.

Answer 5

Quantum Mechanics assumes that particle properties are determined statistically by operations on a wave function representing the particle's probability distribution. The wave function obeys a dynamical wave equation.

Contrast this with Classical Mechanics, which treats particles as points with precisely determined properties which obey a deterministic dynamical equation of motion (Newton's law). Or, as Einstein (who didn't like QM very much) put it, "God does not play dice".

Answer 6

A study of the physical state and properties of atomic and sub-atomic particles and their environment.

There are basically four agreed upon physical levels of reality: the super macroscopic, the macroscopic, the microscopic and the quantum. The super macroscopic are the galaxies and other cosmic phenomenon. The macroscopic is the level you are most aware of existing and interacting on. The microscopic is what it implies, and the quantum is explained above.

Actions on each level affect every other level, although what occurs on each level is dictated by the physical properties of that level. Mass and the space around it simply are affected in different ways depending on the level of corporeal reality it is on, and so there are different physics to explain the phenomena involved.

Answer 8

Physics is study of matter and energy.

Matter ultimately consists of particles like electrons, protons, neutrons and other subatomic particles. In short, we can count the number of particles in any matter.
Matter is quantized - countable.

When material particles interact with other material particles, energy is involved.
Thus energy interacts with matter and matter interacts with energy.

When dealing with microscopic particles, our ordinary concept about energy changes;
Energy is not continuous; they are counted, like particles. We call the smallest pocket of energy a quanta of energy. The smallest indivisible energy quanta is the Plank's constant h = 6.62620 x10-34 J. All energy transformation takes place only in multiples of this number [unbelievable in the macroscopic point of view but proven]

The Physics which deals with the interaction of energy with matter taking into the fact that energy is quantized is Quantum Physics.

Answer 9

The physics by which the behavior of photons, electrons, and nuclear particles is described and predicted by probabilities involving discrete quanta of energy.

Answer 10

which aspects of quantum physics? Not to mention that no matter how simply you put it there will always be more to add, and whatever you say is both right and wrong as there is no true definitive answer.
