Is Quantum Mechanics harder or Calculus?
398571
Quantum Mechanics is harder, it uses calculus, but it also uses unfamiliar concepts such as tunelling and the wave nature of matter.

You could be, but who knows? You might be brilliant! Doesn't one course build upon the other? (Except parts of Linear Algebra, which is somewhat different, however it does use integrals and infinite series and lots of stuff I seem to recall might require that you know differential equations and integration . ) It has been 17 years since I had this series of math in college, but that's what my vague remembrances tell me! I'm not sure how often basic math curricula change over time but probably not that much...

No. you may count yourself lucky to have these conditions because with these you are able to get an unique solution ψ.\nBut there are 4 main conditions:\n\nNorm: |ψ| := 1\n\nContinuity of ψ\n\nContinuity of ψ'    (only for finite potentials)\n\nLimit: ψ(x) -> 0 for x -> ∞

Modern physics deals mainly with two branches: relativity and quantum mechanics. Relativity, in it's general form, deals with accelerated frames of reference suitable for the study of phenomena related to the outer space.\n\nFrom it came the relativistic mechanics, which is the branch that deals with objects moving at very high constant speeds, which are comparable to the speed of light.\n\nOn the other hand, quantum mechanics is the physics appropriate in the microscopic world(extremely small such as molecules, atoms and electrons), this small world uses the Angstrom as a measuring unit which is 10^-10 m, the quantum mechanics is successful between sizes of 10^-14 m (nucleus) to 10^-7 m.\n\nThere is also the Relativistic Quantum mechanics for both small and fast bodies, and there is the Classical(Newtonian) mechanics for large and slow bodies.

Mit has open courseware on their website.  They've been videotaping the classes, but they don't have this for the quantum physics classes yet.  If you just want basic information, then you can check out some of the other physics.

Quantum Mechanics is the Physics behind Physics, it is Philosophy with Scientifical evidence, this goes beyond Logic and reasoning, and it only goes to show that the most incomprehendible thing about reality,(really is after all) the fact that it is comprehendible!!! I have yet to see the movie but the guy who said he and his chick tried to count how many errors were there within the first 15 minuites of the movie but couldn"t cause there were too many,.. yeah well,... He"s a fool if he disregards all things just as easily as he did this, I mean he counted the errors for example with our common (estimate his knowledge of this topic to a high level by the way, I am willing to assume he knows what he is talking about and what he is talking about is Physics, you know Science science,... I love that subject too,,,, but Quantum Mechanics is a modern Science, even more so and 10 fold than the one used for our latest and most newest forms of technology! \n  Ok please do me a favor and research when this subject first made it"s debut, and more importantly Who helped develop this Topic, and I am sure you will be surprised, For now I will give you one name, and it is one that by the way is not the father of this subject, but Albert Einstein himself, was there when they were cooking this Phenonmenal study up, it was a handfull, I mean a "handfull"! of the best most respectable minds of that time and we should be proud, ........ of our era,.......it brought me peace, when thinking about the Pi equation,...... it doesn"t gibe you an explanation Quantum Mechanics, it hardly gives you an understanding, but you do or can come to terms with the fact that life is not an answer it is a question, perhaps............

There is a continuum between quantum laws and classical physics, they just haven't discovered a unified theory that expresses this continuum mathematically. Quantum laws govern all particles, and since matter is comprised of particles - naturally quantum mechanics supports material reality.\n\nuh... to "goring" - quantum mechanics does not posit that light has no mass.\n\nEinstein did not challenge all particle theory - when he said "god does not play dice with the universe" he was challenging Heisenberg's Uncertainty Principle, and quantum laws based on probability, which were subsequently validated in double-slit light experiments. So Einstein was wrong. He considered it his greatest failing as a scientist not to unify relativity with quantum laws in his lifetime.

for sure.\n\nbible is descriptive.... quantum physics is a snap.\n\naren't you glad..\n\nthat way its cover 11 or 12 diminsions where you only think in 3 or 4.

Quantum mechanics deals with anything that can come in fixed quanta, which is basically everything if you get small enough!\n\nMass comes in its fundamental particles, but you have other fixed packets of energy that can be treated with particle behaviour.\nA photon is a packet of light.\nA phonon is a packet of vibrational energy.\nEven magnetic flux in a superconductor has a magnetic flux quantum.

There isn't a definite boundary line.  A molecule of several atoms can exhibit quantum-mechanical behavior under appropriate experimental conditions.  Of course, the heavier the molecule, the more it obeys classical mechanics as opposed to quantum mechanics.  The "correspondence principle" tells us that at a large enough scale, all processes show classical behavior.

Quantum physics underpins everything, but of course you don't need to go that deeply for many practical purposes. For instance, you would not model the architecture of a building at the level of an electron.\n\nBut quantum mechanics is central to understanding and designing all semiconductor devices (not just the newer, esoteric ones), hard drives (which use quantum tunneling), chemicals that require an understanding of the chemical bond (including modelling shapes of biological molecules in the biotech iindustry).\n\nIt is behind MRI scanning, x-rays, digital cameras (a CCD is a fundamentally quantum device), nuclear energy and weapons technology.\n\nIt is essential to cosmology and understanding the stars.\n\nThe list goes on.\n\nAnd no, it is way beyond the status of a theory.

As far as I understand it, most disciplines of "hard science" are built on principles of mathematics, but mathematics in of itself is not considered a "hard science." As more advanced it becomes, the more theoretical it gets, and starts to resemble something like philosophy.

its only hard if you make it hard\n\nbe prepared to be very good in math and physics..

under quantum mechanics...\nit's a thought experiment, called the EPR paradox...\nthis paradox is more severe or seious than schroedinger's cat paradox...\n\nquantum mechanics says that a motion of a particle can be deermined by its wave function, thus the results of an experiment or probabilities or predictions...\n\nbut E, P and R thought that this is true only with statistical distributions of the particles tested by the experiment (the properties of particles)...

Quantum mechanics is fascinating, as Einstein's famous quote that "God does not play dice with the universe" is turned on its head.  The random nature associated with the inner workings of atoms and quarks is astonishing when one considers that despite all of the unpredictability of subatomic activity, things in the macroscopic world follow predictable patterns that seem to defy common sense.

I think Finite Mathematics is harder but I like it more than Statistics. I get bored w/ Stats.

the formulas are what convince me.  I've had to derive so many complicate formulas myself, and most of them, especially mechanics formulas can be proven, such as measuring a quantities, solving for a missing variable, then doing an experiment and getting the same answer.  This is too much to be a coincedence or something.  Most theories and things are developed before formulas and actual mathamatical relationships are found, then they find them and it all fits together nicely.  Even with reletivity and things with spacetime, there are a lot of concrete formulas, and once you have the satisfaction of deriving them yourself from previously proven formulas... it all clicks nicely, that's why im a physics major, curiosity about everything like this.  I guess human perception can be valid once connections start being made between things, because when ideas are incorrect, they really don't connect to other things very easily.
