Actually, in coil electrons don't move in circle, but in spiral. Single electron is just once passing through wire. When electrons flow in one direction in coil of course it will produce magnetic field, that anybody with compass array device can see on his own eyes. But if we will use alternating current, electrons flow once in one direction, once in opposite direction. Can you detect magnetic field when frequency of AC would be counted in millions or billions Hz? What does show compass array device, if you will place it close to coil through which there is flowing low frequency AC, or high frequency AC.. ? What does show compass array device, if you will place it close to discharge tube with Hydrogen and turn high voltage on to ionize it.. ? The issue I see here is that spectral lines are obtained from discharge tube, with ionized plasma. But electric neutral Hydrogen gas is not mixture of proton and electron, but H 2 molecule, two protons and two electrons. ps. Where in USA and UK somebody can buy compass array like below one? I searched couple times on Google and can't find anything.. Here it costs $40 in the regular shop. Whenever somebody asks on physics forum about moving electron in circle around proton I know they don't mean it literally. Circle is 2d figure, with missing one axis to 3d.

The frequency ν 0 and the energy E 0 of the electron in the H atom at the ground state should consistent with quantum hypothesis, that is : E 0 =h ν 0 Where h is Planck's constant . As we known, the period T and the frequency of the electron must obey the following relationship : T=1/ ν Clearly, the electron is moving around the proton with a constant period T 0 , and T 0 = h /E 0 According to the concept of period, the moving electron should be at the same position at the time after a period T 0 .

WKB approximation is only a mathematical method or semiclassical calcultion for finding approximate solutions for the quantum sysytem, the reliability of results depends onwhether the Schrdinger equation of the quantum system is correct. By my opnion, Schrdinger equation could be used to describe the resonance of the orbit in atom, eigenvalues of energy from the equation's solutions decide the eigenvalues of orbit radius. For the H atom, we can get eigenvalues of orbit radius of the ground and resonate states by solution of Schrdinger equation, and the elelctron moves along one of the eigen-orbits which obey the control of the Lorentz force. In addition, H atom is only at the ground orbit for the isolated state, and could be at high eigen-orbit by outer resonate field. Edited by Jeremy0922, 22 July 2014 - 04:13 AM.
studiot studiot Scientist Senior Members 3,901 posts Location Somerset, England Posted 15 October 2014 - 02:40 PM Jeremy 0922 A scientific theory or model about nature must obey scientific rules,such as logic, causality, and could completely not partially be confirmed by the facts Well that is not the way we learn, teach or practice Science from an early level. Take for instance the typical highschool maths questions 'A mass M is suspended from a light inextensible string...............' A rigid rod of length l supports two blocks....' 'A frictionless pulley.....' Yet these methods yield reproducible results adequate for many purposes. People every day bet their lives on calculations known to be inaccurate or based on known false assumptions because observation (experience) has shown that those calculations are adequate for purpose. Sometimes we have results without explanation and scientific theories are offered a conceivable explanations, such as the reversing magnetic fields of Earth, but we do not rely on them because they also predict effects we do not observe. Sometimes we have theories that offer apparantly good explanations and the authors of better ones struggle against the establishment to promote them, (isotasy v plate techtonics for instance), but usually further observations come to light which weed out the inadequate. These days we seek corroboration or exception more actively than ever, because we are aware of this. But we should always be wary of specifying how any theory 'should be' . I said 'adequate through experience' above this is a process that gives us increasing confidence in a theory as we make more and more observations that agree with its predictions, but fail to find exceptions.

In science, the main metric of how good an idea is: how accurate of predictions does it make. In many ways, it doesn't matter if the idea is based upon the wishing of fairies riding unicorns, the most perfect logic, or the most imperfect broken logic. If the idea predicts x, and we measure it as x.... then that idea is scientifically strong. On the other hand, if an idea predicts x and we measure y, then clearly there is an error of (x-y). Logic has failed us before. At one time, it was logical to think that earth was flat. x=flat earth. But, when we finally measured y=mostly spherical earth, then clearly the idea that predicted x was wrong. For us to believer your idea, appeals to 'logic' alone doesn't matter. Today, we measure y about the state of an atom. You are predicting x. Current best theory predicts z. We know what z-y is. Please show us what x-y is. Show us what predictions your idea makes. That is the most important thing right now. Appeals to 'logic' aren't going to get you any more support.

For example, both Newtonian gravity and GR make predictions about the effects of gravity. In many cases, they are equally accurate. In some cases, GR is (significantly) more accurate. That does not mean that GR is true and Newton is false. (Or that one is more logical than the other.) One model is more accurate than the other.

Since the results of the accepted model do agree with experiment, any perturbation to it that has not been included in the model is too small to currently matter. Abandoning the model will only happen if it stops agreeing with experiment or a better model comes along. We are discussing the logic relationship between the experimental data and the hydrogen atom model of quantum theory. Your answer is about resolution of measurement, and is an other question. 0 Trust Science.

Your answer is about resolution of measurement, and is an other question. I'm trying to discuss science. You appear to be claiming that the accepted model is wrong, and the only way to do that is by comparing the model to experiment. The accepted model does not include the gravitational attraction of the electron and the nucleus, either, because we know how small it is — it can be safely ignored. For your claim to have merit you have to show the effect exists AND it is large enough to make a difference. 0 Minutus cantorum, minutus balorum, minutus carborata descendum pantorum To shake my vodka martini, click the up arrow ^ I am not a minimum-wage government shill.

There is no logic relationship - there is only the predictions of theory versus the measurements. You have no predictions (other than it is yes or no, which is not very helpful) therefore your comments are not useful.

It would be necessary if science was the quest for an ultimate truth - but science is an empirical investigation through models, predictions, and experiments. Nature is under no compunction to agree with my arrogant monkey logic - but if I am doing science then I am compelled to take empirical evidence as the only yardstick of truth. The logical beauty of a scientific theory is of no use whatsoever and can be positively dangerous - we only need to look back at classical Greece to see this. Maths, logic, philosophy were at an amazing (local) peak but whole swathes of observational science were at a standstill because logical beauty trumped observation. This continued for hundreds of years; medicine, biology, astronomy and most disciplines in Europe laboured through to the Renaissance with easily disproved theories which were both ancient and logically necessary but hugely wrong. We adhered to these ideas for the same reason as you are failing - it is all too human to believe there must be an accessible base narrative which explains everything in a logically sound, mutually non-contradictory, and pleasing manner. But firstly we have no reason whatsoever to think nature functions in such a manner, we can probably never understand at such a basic level, and finally we only have observation with which we can honestly probe nature 0 A little learning is a dangerous thing; drink deep, or taste not the Pierian spring: there shallow draughts intoxicate the brain, and drinking largely sobers us again. - Alexander Pope feel free to click the green arrow ---- Back to top #113 swansont swansont Shaken, not stirred Moderators 29,431 posts Location Washington DC region Posted 15 October 2014 - 01:10 PM You think logic relationship between experiment and theory is unnecessary! To the extent that it is necessary it is also insufficient. No theory stands solely on the logic used to develop it. Geocentrism was logical. Phlogiston was logical. The plum pudding model of the atom was logical. But both those and countless others failed because they did not match up with observation; all were ultimately shown to be founded on a false premise. 0 Minutus cantorum, minutus balorum, minutus carborata descendum pantorum To shake my vodka martini, click the up arrow ^ I am not a minimum-wage government shill.

“…… , I have just read your paper. Interesting ! Very interesting ! ” 这是一位网友在美国科学论坛网 SFN ,发表的阅读我的论文后的评论,算是我在 SFN 上发帖介绍我的学术观点,展开的一系列争论平息后,得到了一点点回报吧! 在 SFN 上注册,发表自己的学术观点,至今已有 3 年零 3 个月,我目前是该网的高级会员,针对氢原子结构和光谱理论、量子力学与相对论科学基础问题,发启了 5 个话题,共发帖 99 个,由于 我的观点的出发点基于经典物理理论,属于主流思想之一,并且没有个人的假设。因此,我的论点没有受到任何警告。 在 SFN 和中国科学网 ScienceNet.cn 发表个人的学术观点和理论,目的是简单且明确的,希望通过这种传播速度快、影响面宽的新型媒体,介绍相关的学术内容,并希望得到读者的理解和支持。事实上,下定决心在网络公开自己的观点是需要巨大的勇气的,因为 一个不成熟的,甚至是幼稚的观点,可能会给自己的学术前途带来巨大的负面影响,在国外的网络上发表还可能有损于国家和民族的形像 。因此, 我在 SFN 上的每一次发帖都是经深思熟虑,有完全取胜的把握后,才会将相关论点发布公开 。 目前在关于量子力学、相对论的科学基础,氢原子结构的个人新理论的 5 个公开议题的激烈争辩中,没有出现过明显的失误,绝大多数的个人看法和观点在辩论中得到了认同或取得了优势。 在氢原子结构和光谱的量子力学观点与我个人的电磁学模型的争论中,由于 我的论点对量子力学持否定态度 ,令 SFN 上的物理学家十分的不快,并 展开了激烈争辩 ,讨论的 内容包括了能量守恒问题、电场传播极限、理论与观察坐标系关联等问题 ,同时对方也对 电磁学模型是否能解释角动量、电子干涉、光谱精细结构等提出了质疑 , 经过长达三年多的辩论, 这些问题逐一都得到合理的解释或澄清 。我认为已经达到我最初目标,揭示了量子论的内在自身难以克服的矛盾,让大家了解并初步接受了氢原子电磁学新模型。最近在 SFN 写了一段总结性帖子,作为这一阶段的结尾: “ Classical theory not only can explain electromagnetic phenomenon caused by charged particles, but also prove the steady ground orbits with non-zero energy, and Schrodinger equation could be deduced from the resonance of the ground orbits, which could be applied to explain spectrum of atom . By the solution of Schrodinger equation, Quantum mechanics could interpret the structure and spectrum, but cannot explain classical electromagnetic phenomenon. Therefore, I think classical theory is better than QM for the treatment of charged particles system, including atomic, molecular, and solid-state structure . ” 对于量子力学和电磁学应用于带电粒子体系理论描述的如此评价,没有招来与我一直进行激烈争辩物理学家的直接反对,之后一些网友通过电子邮件表达了他们支持我的态度和立场,并认为量子力学存在错误。此时,我总算长长地松了一口气,二十多年来的痛苦思索、八年多时间不懈坚持,没有白费。 由于版权的原因,我不能将 SFN 论战的全部内容,直接转载于此,只能将一些情况作一个简约介绍,目的是希望大家了解相关情况,不要认为我是一位异想天开的狂人,是一位“ XX 的民科”,利用严肃的科学网站传播伪科学。 最后我要再次强调: 欢迎大家以真诚的态度与我共同探讨学术问题,来者不拒,而且我不会回避任何问题! 如果那位只是为了让我“闭觜”,不是以科学的论据进行有效的反驳,而是以代人格羞辱的“ XX 的民科”,甚至不假思索地给我戴上“伪科学”传播者的帽子,我会毫不留情地对此行为发起强烈反击!!
这不是我个人的预言,而是对一件客观事实的陈述! 2012年9月22日,我的生日这天,刊登了我的文章的GED杂志23卷4期寄到我们中心,此时我还在广州中山大学CPS2012秋季学术会议会场。得知这一消息,令我长长地松了一口气,也是我今年48岁生日的最好礼物吧,论文总算在学术期刊正式出刊了。 关于氢原子结构的个人新观点通过网络、报纸和学术期刊三个方式,使得相关理论可以在短时间内得到快速广泛传播,是一件十分令人愉快的事。 采用Google搜索工具,搜索“氫原子結構”有近200多万条相关结果,我的博文和科学日报的报道排在结果首页2-5位,“氫原子結構”图片搜索结果为第一位。 搜索“量子的解释”关键词有4100万条结果,我的系列博文“关于量子的解释(1)-(5)”一直列于结果首页的前列。 氢子结构和光谱是量子力学解决原子结构和光谱最为成功的例子,由于计算出的氢原子光谱的精确程度已经超过了实验测量的结果,因此被誉为目前最精确的理论。量子力学是建立在一系列基本假设基础之上,但对于原子分子的基态不能进行“物理”的说明(或证明),更不能解释带电粒子的电磁性质。因此,我认为量子力学并不是原子结构的终结理论,经过二十多年的努力,采用已知的经典物理理论,对氢原子的轨道结构及共振进行了认真细致的研究,得出了辐射耦合状态下的氢原子基态,及其共振的数学表述,并经相关的数学变换,推导获得了与目前量子力学中的普朗克量子假设和氢原子定态薛定谔方程,完全一致的数学方程。 因此,我们完全有理由相信,氢原子的结构和光谱辐射现象属于电磁学问题,其线光谱辐射是轨道的共振效应。我的这些观点在网络(中国科学网、美国SFN网)公开之后,引起了很大的反响,通过相关的学术交流,表明氢原子新理论没有学术上的问题,能很好地解决目前量子力学能够解释的氢原子结构和光谱现象,并且与目前的经典电磁学理论是完全相容的。 我认为GED杂志23卷4期上发表的关于氢原子电磁辐射和稳定性的文章“ Electromagnetic radiation and stability of the hydrogen atom ”,是目前关于氢原子结构,由中国人独立完成的最完美的模型,必将载入科学史册,成为科学的标准知识进入物理教科书。
