I do not really understand quantum physics, some hel;p, please?

Question

I mean I sort of understand but the dimensions and super strings really throw me for a loop. somebody plese help me uderstand.

Answer 1

A thorough understanding of quantum physics is beyond the realm of a Yahoo answers response.

According to Edward Witten, if quantum physics doesn't make you dizzy to think about, then you really don't understand it.

Answer 2

Quantum physics deals with the wave properties of matter. Physicists have been able to make a beam of atoms behave exactly like a light wave, for example. The equations of quantum physics are among the best and most accurately confirmed by experiments, so it's silly for anyone to claim that quantum physics is still "only just a vague theory". String theory is an extension of quantum physics, but unlike wave properties of matter, string theory is yet to be confirmed experimentally.

Answer 3

There's absolutely no quick way to summarize quantum physics; it's a topic far too complex and flooded with abstract mathematics. Super-string theory is strictly a mathematical system with absolutely no hard, verifiable evidence that any of its concepts are true. Quantum physics, although containing some aspects of super-string theory, has several aspects that can and have been verified as being physically real. Overall, quantum physics and super-string theory apply within spatial sizes smaller than 1.6^minus 35 meters (..1.6 preceded by 35 zero's).

Answer 4

Quantum mechanics is an application of math in order to predict the behavior the microscopic world. The idea works well but continues to be controversial.

Scientists were unable to understand the behavior of radiation emitted by a blackbody using classical physics until Planck could show (mathmatically) that if energy is released in packets of energy, the experiemental data fit the math. This lead to Einstein's famous paper on the photelectric effect and that light could behave as particles or photons. Further developments by other begin to paint a strange world.

-A world where all probabilites can exist. Where an observed cat was both alive and dead at the same time (Schrödinger).

-The inability to predict where particles are at any given time (uncertainy principle)

-An instant awareness between everything. Even though message travel is limited to the speed of light.

-Light acting as both a wave and a particle depending on the experiment or observation. (Feynman noted that one needed to come to terms with slit screen experiment and wave-particle duality of light to grasp quantum mechanics. I am still at that point)

Our intuition tells us there is something wrong. Even Einstein in later years grew frustrated with the application of probility used to describe the quantum mechanics world by noting that "God does not play with dice".

But the application of math continues and we are limited in our instruments and observations to fully understand or prove if what we observe is real or just an illusion. Not many disagree with the math, it is the application to the real world that is most difficult and where disagreement exists. I doubt you will find anyone who can prove to you the theories you mention in your question other from an math standpoint.

A fascinating topic. The reference below discusses the controversy under philosophy, not physics.

Answer 5

there is not any shrink to mind's eye, that's in a fashion comprehension because of the fact imagining issues a distinctive way enables know what quantum physics are approximately. and you certainly could use mind's eye to understand quantum physics, because of the fact it somewhat is in contrast to known physics or some thing you will discover and tell each and every thing approximately basically via looking. the element with quantum physics is that debris behave randomly, you could no longer tell the proper place or how briskly that is going. you're able to correctly be attentive to one yet no longer the different. The uncertainty will become greater suitable with wave particle duality thoughts and such. At such small stages of length, the habit of the debris themselves, like the skill of them to bypass via any remember, is amazingly distinctive from what we are was attentive to approximately known physics. Dimensions additionally play a evaluate this, debris flow around in multi dimensional area that a known human thoughts could no longer understand of course with out having the belief defined thoroughly to realize it. The human thoughts invented math and physics with mind's eye, that's countless, the international around them created the bounds to which they made for information. Even Einstein himself pronounced "mind's eye is greater important than awareness". It creates revelations and concepts, this is why there are clever human beings and clever human beings.

Answer 6

Don't worry about it. I've taken graduate level courses in quantum physics - they just don't teach that stuff, really, even in physics grad school. It's not required - you can take elective courses in general relativity and field theory, but they don't even teach string theory because so many people doubt that it will pan out in the long run. If you're looking for the basics, try wikipedia. If you're looking for the math, you're probably out of luck if you don't have a few years of physics and calculus behind you.

Answer 7

I don't think anyone really "understands" quantum mechanics in any kind of intuitive sense. This is because the interactions of small particles are so far removed from our perception and experience. My advice to you is to trust in the math. I don't put a lot of stock in superstrings and string theory because their existance is not experimentally verified. For now, they are just a convienient mathematical construction used in an attempt to create a grand unification theory.

Answer 8

Quantum Physics is easy - Basically the quantum world is where the potential lies for the organazation of matter and energy, since we know from E=MC2 that energy and matter are diffirent aspects of the same thing, it is here in the quantum world where the functionality of our physical world is created.

Answer 9

We shouldn't close our minds to other possibilities. Its jsut a slight possibility that a theory based on uncertainty itself is......well.....uncertain.
