AkinPhysicist:is there any experimental proof that an electron could be in a box and outside a box at the same time, there is none, thts a theory, there is a proof of the wave-like behaviour of electrons(double slit),you seem not to be following the argument, i am not disputing the verity of this fact, but i am disputing the reason provided for it.The double slit experiment explains the wave-like behaviour, due to the effect of superposition.Generally we ascribe this to the probablistic behaviour of electrons, but i dont agree with this fact.A theory in this regard is a proposal meant to express a fact,the theory could be correct but the reason provided for the theory could be reasonable but tht does not make it true.So in certain cases, a theory could be a reason for an occurence,in other cases a theory could be the occurence itself.We need to understand which stance a proposal takes. 2.to some extent my point on wave-particle duality is not a theory, its is my proposition about the reason for which that exists. 3.you are missing a point, you mistook electromagnetic field for electromagnetic wave.The latter is emitted by a decelerating, due to a change in the intrinsic electromagnetic field.So a non-accelerating electron has an intrinsic electromagnetic field, but an accelerating electron could mean a change in the electromagnetic field, but it does not mean electromagnetic field does not exist, it means the electromagnetic field component(electricand magnetic field) vectors have changed.I hope u get my point. 4.I agree that i should have been more specific, about my point, nt just saying its a theory, but was not wrong by calling it a theory,i was only vague.In other words, it is a theory that explains a theory. 5.The simultaneity of the position of electrons, in my opinion, is due to our desire to characterize the position of an electron,what i mean by this is our trying to measure its position, how do we measure the position of an electron without changing its position., so in other words our measurement could influence our definition of position, are we defining the actual position or measured position. |

benji93:1. Guy- you don't know what you are talking about. Quantum Tunneling was confirmed decades ago. It is one of the experimental corner stones of quantum physics.You still do not understand double-slit experiment - please go back and re-learn it. The fact is an electron behaves both as a particle (photo-electric effect) and as a wave (double-slit experiment). 2.As long as you are not disputing this fact, then we are good. 3.You don't understand Electromagnetic fields. Go and re-learn it. EM fields are generated by accelerating charges - no such thing as the mysterious ambient/intrinsic EM field you seem to be suggesting. Please go and re-learn this basic stuff. |

AkinPhysicist:you are wrong," is there any experimental proof that an electron could be in a box and outside a box at the same time", you missed the point, i used the word "simultaneously", this phenomenon described above does not mean quantum tunnelling,quantum tunnelling is the process by which quantum objects including atoms pass through barriers,especially when a barrier initially reflective is made thinner. 2.Yet again you are assuming a stationary electron cannot be charged, which is the same as assuming tht a stationary proton cannot be charged. If you agree that electrons are charged. 3.What is a magnetic force? Basically F=Bqvsin(theta)(v=velocity), so an electron does not have to be accelerating to be affected by a magnetic force, and y would the constant velocity electron be affected by a force, if it does not exert such a force itself?so a constant velocity electron must be producing a magnetic field itself, well it will accelerate due to the external force, but this is only because, it has a tendency to accelerate or accelerate another entity by virtue of the force field.Before the electron moves it accelerates from rest,thts fine, but this time i am talking about the state by which it is moving at a constant velocity.I repeat again, you need to reevaluate ur knowledge bro,its a fact that electromagnetic radiations are emitted by accelerating charges,this does not mean non-accelerating charges to not produce electromagnetic fields-an electromagnetic radiation implies an electromagnetic field, but the reverse is not true. because by virtue of the aforementioned, electrons moving at a constant velocity should produce both electric and magnetic fields. Now let me refer you to an argument tht will help us tread on the same lane.How is an electromagnetic radiation produced, you might say an accelerating charge.But literally and deeply electromagnetic waves are produced by oscillating electric and magnetic field, this oscillation implies, there is a change in electric and magnetic field, so we can thus say an accelerating charge can produce an electromagnetic wave(sometimes it does not).But we are talking about changing electric and magnetic fields here not the presence of electric and magnetic field itself.The electromagnetic field can be present but not changing,so an electron moving at constant velocity can produce an electromagnetic field but not a changing electromagnetic field, hence no radiation of electromagnetic waves. summary i.the electric field produced by the electron is intrinsic, regardless of whether it is moving or being at rest. ii.a magnetic field is produced by an electron in motion, be it uniform or non-uniform,that is explainable by the expression F=Bqvsin(theta).So a stationary electron cannot produce a magnetic field, by virtue of the expression iii.an electromagnagnetic radiation is produced by a changing electric and magnetic field. You need to have an open mind bro.So tell me why you think an electromagnetic field is only produced by an accelerating charge(electron) |

SHALOM! I know that you mean well, but using THEIR version of Reality makes us their Subordinates and their Slaves. With all this "QUANTUM KNOWLEDGE," can you, or any other Engineer revamp our POWER GENERATION TECHNOLOGY, so that we can have Electricity, 24/7? On NATIONAL Scale? STATE Scale? TOWN Scale? Or ONE HOUSE- such as your own? I think not. If you set out to execute such a project, YOUR TRAINING will tell you that "you need this," "you can't get that," "that is too expensive..." and at the end of the day, you end up doing nothing. Whereas, Engineers have come forward- such as Lieutenant-Colonel THOMAS BEARDEN if the US AIR FORCE (retired) - proving that PHYSICS HAS BEEN FALSIFIED- that the ORIGINAL Electromagnetism Equations, written in something (above my head,) called QUARTERNION ALGEBRA, proves that Electricity can be generated NATURALLY, and INDEFINITELY- without a POWER SOURCE! But to HIDE this Knowledge from the PUBLIC, the equations were rewritten into something called TENSOR ALGEBRA, which makes the Scientist think that an Electric Circuit must consist of TWO POLES that CANCEL EACH OTHER OUT! People have practicalized this Knowledge- then died mysteriously, when they tired to practicalize it. THOMAS BEARDEN was going to produce an Electric Car that used his MOTIONLESS ELECTROMAGNETIC GENERATOR- which has been built and demonstrated at the tabletop level, producing 500W, merely powered by a motionless magnet- in 1995. He shelved the project, saying, that one can build such a car- but one won't be around to drive it! The mistake that these people always made was that THEY INSISTED on trying to commercialize their inventions in AMERICA. Where the OPPOSITION is STRONGEST. Had they come to AFRICA- and introduced the technology in a SENSIBLE manner, they could wind up with TEMPLES erected in their honour! I should be interested to know what PRACTICAL USE "QUANTUM PHYSICS" and "QUANTUM CHEMISTRY" has ever been put to in Black Africa. |

promqueen247:..quantum physics still have loopholes that only relativistic physics can explain...thats what i finding interesting atimes.I felt quantum physics was a desperate way for physicist to answer a lot of unsolved questions...when delving into the realms of string theory, entangalment, multiverses etc it really gets confusing and many of the theorems are not holistic in answering questions.... |
| Re: Basic Concepts Of Quantum Physics by mvem(m): 11:52am On Feb 16, 2017 |
oaroloye:...not all sciences are meant to be applied just like pure physics and pure maths...they are done for beauty of it, thats if u understand what i mean....some theories are very abstract and pure but no one can say that it is useless because in the next 100 years it might be applicable and game changing....just look at relativity that was known as abstract and not making sense but now it is very fundamental in a lot of tech |

benji93:Once again you show an abject lack of knowledge of the fundamentals of quantum physics. The ONLY way the particle in the box can have a non-zero probability of existing outside the box is through quantum tunneling. Because the wall of the box represents 'infinite potential' there is no classical way the particle can surmount this 'obstacle' hence quantum tunneling. You have described quantum tunneling but yet you believe its something else. Simultaneous? Of course - the wave function is always represented as a snapshot in time. Go and review your undergraduate particle in the box notes and you will see the wave function is represented as a function of position NOT time. What you have described is quantum tunneling which has been confirmed experimentally decades ago. Your lack of understanding is confusing you. benji93:You have a long way to go in understanding basic physics let alone quantum physics. The charge of an electron is intrinsic. The idea of 'charging' an electron is nonsensical. You are confusing static electric field of a charge with EM generated by an accelerated charge. Now, if I grant your ridiculous claim that static electric field is the solution to explain the wave nature of subatomic particles then, how do you explain the wave behavior of a neutral subatomic particle like the neutron?. Your 'theory' fails because it doesn't even pass a cursory logical test. This is because you don't understand physics. benji93:Another evidence of lack of basic understanding. The equation you wrote says a particle of charge q and velocity v INSIDE a magnetic field of strength B will experience a force F. This force is the force the magnetic field EXERTS on the charge. This is different from the charge itself GENERATING an EM field due to its vibrational (accelerating motion). You are showing a lack of understanding of basic concepts. You need to calm down and think. benji93:The same way a car moving with constant velocity experiences a force when it is rear-ended by a tipper -what don't you get? You are confused because you don't know basics. The field of a charge does not affect the charge itself but other charges around it. This is high school physics 101 - go an review it. benji93:So? What has that got to do with EM field generated by accelerating charge? And how does that help your 'theory'? benji93:Word jumble makes no sense. Reword it or forget it. benji93:Everything I posted is backed up by experiment. Go and check it. benji93:Long epistle but still does not explain the wave behavior of a neutral subatomic particle - this is why your 'theory' fails. If your 'theory' only applies to charged particles then it is of no value. benji93:So? how does this help your 'theory'? benji93:Your formula is incorrect. F is NOT magnetic field produced by the electron. F is magnetic force exerted on the electron. Please go and learn basics. The formula you want is (is the cross product formula): B = constant qv X rhat/r^2. This is the magnetic field produced by a charge. benji93:Trivial - physics 101 benji93:Trivial - physics 101 |

fabre4:The Hamiltonian is an operator representing the total energy of the system. To get the total energy of the system all you have to do is compute the EXPECTATION VALUE of the Hamiltonian. This computed value is basically your total energy. Computing expectation value is trivial - if you need help I can show you. |

Quantum physics proofs dat science and spirituality are interrelated. Quantum physics reignites a new phase of spirituality. I am a quantum leaper, I believe that every individual Running about an orbit must at one point in time take a leap or cease to exist. Then there's a concept of wandering stars. These were revolving round an orbit but did not gather enough energy to quantum jump to the next orbit thus fell off the circle. Will be righting an article on quantum physics and conceptual age spirituality - what we should know. It will teach how to use quantum physics to attain a immense spiritual heights. Sgt Ponzi Hater |

AkinPhysicist:People like u end up wearing one old worn out trousers for months. Quantum physics brought a rebirth to spirituality. The bible says "things which are seen where from things which are not". That phrase it self explains the invisible part of matter. I know your feeble academic frame cannot withstand this and you'll resort to insults. Know the academic aspect of quantum physics will do you no good, understanding how it affects your everyday life changes the whole picture. I am a quantum leaper and I keep making quantum leaps in life because of my sound practical knowledge and spiritual illumination on quantum mechanics. Sgt Ponzi Hater |

ponzihater:Unmitigated thrash. There is no such thing as a quantum leaper. The writers of the bible have ZERO idea about quantum physics. Stop deluding yourself. |
| Re: Basic Concepts Of Quantum Physics by Nobody: 8:15pm On Feb 16, 2017 |
AkinPhysicist:You are too young to begin life like this. Google is your friend browse quantum mechanics and spirituality or Christianity and you'll several well framed article on the matter. The fact that you can't articulate the subject title doesn't discountenance it. Open ur lazy skull and research. And if you can't do that STFU. David Van Kovering is a scientist of repute but discovered the connection between quantum mechanics and creation and marvelled at the possibility. Enjoy ur evening Sgt Ponzi Hater |
