Line spectrum of hydrogen atom

The Ruther Fords Alpha particle-gold foil experiment has proved that most of the mass of an atom is concentrated only in a very small region and thus he called this region as the nucleus of atom. Ruther Ford proposed that (BUT WITHOUT ANY EXPERIMANTAL EVIDENCES) electrons revolved around their nuclei in circular orbits with which are just sufficient to balance the attractive force by nuclei. Unfortunately no scientists have questioned this high-speed motion of electrons around the nucleus and this was the beginning of the development of many misleading theories in the history of physical science. Matter wave, uncertainty principle, electron cloud around the nucleus, wave particle duality for particles etc. Charged particles like electron have a standing- electric field and magnetic field in right angle regardless of any kind of its motions.Uncharged particles like neutron have a standing- magnetic field.Since the standing- electric and magnetic fields, an electron cannot travel in a straight line when it accelerated.When a neutron is accelerated, its standing- magnetic field makes it to oscillate. In essence, a particles standing field lines is the reason for the wave nature when it moves at a high speed.The Davisson and Germer experiment showed that particles behave as wave when they are accelerated. But without knowing the structure of particles they blindly supported the Louis DeBroglies matter wave theory.This matter wave theory has led to the development of the quantum mechanical model of atom.The model says that, the nucleus of an atom is surrounded by a series of stationary waves. These waves have crests at certain points, each complete standing wave representing an orbit. The absolute square of the amplitude of the wave at any point at a given time is a measure of the probability that an electron will be found there. Thus, an electron can no longer be said to be at any precise point at any given time. This series of stationary waves by the electrons are used today for explaining all phenomenon that generated by atoms. Jumping of electrons: The space matter density decreases with the increasing of the distance from the nucleus. When an electron oscillates in an atom, for the every oscillation toward the direction of the nucleus, the high density space matter in the inner region of the atom expels the electron to an outer low density space matter region. Line spectrum of hydrogen atom: When the electron shell of a hydrogen atom is excited it will oscillate in its natural frequency, and so the electron present in the shell. This oscillation of the electron causes the emission of the shortest wavelength Lyman series photon (because that frequency is the natural frequency of the electron shell of hydrogen atom) and jumps from the shell to an outer transitory shell. If there is no any further excitation for the atom, the electron will instantaneously falls back to its original shell. Also, this fall into the shell can cause, the shell get excited in a nominal fashion and the emission of a low intensity photon in the natural frequency of the shell. But, if the transitory shell (to which the electron has initially jumped) is simultaneously excited by some ways (for example, collision of an energetic electron from an external source-in a discharge tube or collision between atom),the electron will again get excited and emit a photon in a longer wavelength, in the natural frequency of that transitory shell. Also, this excitation of the electron causes a further jumping to a more outer transitory shell, and these processes can be continued until the electron is expelled out from the atom and to turn the atom into plasma of hydrogen at a very high temperature.For very jumping of the electron to a more and more outer transitory shells, and the excitation of that transitory shell can cause the emission of more and more long wavelength photons, and this is the reason for the emission of more long wavelength photons like Balmer series, Paschen series, Brackett series, Pfund series etc. http://www.physics-edu.org

The LHC - The Large Hadron Collider ( L.H.C )

The Large Hadron Collider is the largest and most complex scientific instrument ever built and the highest energy particle accelerator in the world. The accelerator is located 100 m underground and runs through both French and Swiss territory. ( 27km circumference) Year 2008 September 10th, marks the culmination of 20 years of work by over 8000 scientists thousands of engineers, technicians and support staff from over 80 different countries. some critics say that this could create a black hole and suck up the entire world. but many say that even if a black hole is created it will vanish within a millionth of a second.. for more info follow these links. (i think the best footage/documentary from the LHC) http://www.youtube.com/watch?v=_fJ6PMfnz2E http://lhc-first-beam.web.cern.ch/lhc-first-beam/Welcome.html http://www.youtube.com/watch?v=bg0r7nfXhGw http://www.youtube.com/watch?v=s9XotvwgnaY http://au.news.yahoo.com/a/-/world/5005914/physicists-firing-atomsmasher/ this video is done by Chris Mann, (the link: http://lhc-first-beam.web.cern.ch/lhc-first-beam/Welcome.html ) CERN- European organization for nuclear research /lhc first beam.

Large Hadron Rap

Rappin' about CERN's Large Hadron Collider! Links below... Apparently YouTube fixed the sound! Still, Will Barras made two options trying to get around the original problems: Other YouTube:http://www.youtube.com/watch?v=T3iryBLZCOQ Vimeo: http://www.vimeo.com/1431471?pg=embed&sec=1431471 Vimeo is downloadable if you log in. There has been a lot of interest in the original mp3, lyrics, and vocals for remixing. You can find all that here: https://www.msu.edu/~mcalpin9/lhc_rap/largehadron.html There's also been interest in translation. You can get a subtitle-free version from Vimeo here (downloadable): http://www.vimeo.com/1730771 With backing track available here (with and without Hawking-style voice): http://barras.ws/rappin.html Go ahead and translate, rap it, and post it! Just give us a shout-out, and it's probably a good idea to include the following credits ;-) Images came from: particlephysics.ac.uk, space.com, the Institute of Physics, NASA, Symmetry, and Marvel I forgot Einstein Online, and they called me out: http://www.einstein-online.info And I forgot Physics World (dunno what I was thinking when I put together the extra dimensions bit). Steve Abel set me to rights (but made no demands): http://physicsworld.com/cws/article/print/403 The talented dancers doubled as camera people, with some work by Neil Dixon. Stock footage is CERN's. Will Barras is responsible for the killa beats: http://www.ling.ed.ac.uk/~s9527813/ And thanks to MC Hawking, who first thought of using computer-voice to bring Stephen Hawking to the world of rap :-) http://www.mchawking.com/ The rapper has a day job (we agree this is a good thing) as a science writer. http://www.katemcalpine.com They'll have a lot of data to sort. 15 million GB per year, actually.

Uncovering the Universe: Latest news from the LHC

The Large Hadron Collider (LHC) at CERN is the most powerful particle collider ever built and has been described as the world's biggest science experiment. Designed to answer the unknowns in particle physics, including the reason for so little antimatter in the universe and the exact locations of dark matter and the missing Higgs particle, the LHC is capable of recreating the conditions that were in existence one fraction of a second after the Big Bang. Tara takes the stage at The Royal Institution to reveal what has been discovered at the LHC since its first year of operation. This event took place at the Ri on Wednesday 19 October 2011.

The Higgs Boson

The video is exactly 4:00 - YouTube adds a second. In which Hank takes a few minutes out of his busy vacation to talk about the Higgs boson, the Higgs field, and what they mean. We know a remarkable amount about this universe, but as of this week, we officially know a lot more. It's pretty freaking exciting, and I'm very pleased that our world is still committed to this kind of pure science and discovery. Thanks to Henry Reich of Minute Physics for looking this video over and making sure I'm not totally full of crap.
