We can take part in their effort thanks to Internet,the World Wide Web (invented at CERN), BOINC, VirtualBox, etc. Tullio |

LHC back in collision mode On Saturday evening proton collisions resumed at the world’s most powerful accelerator and the experiments began collecting data once more. At present, 152 bunches of protons are circulating in each direction in the 27 kilometre machine, but the goal is to increase the number of protons over the next two weeks to close to 1000 bunches per beam. ![]() Tuesday, 7 July: a proton-proton collision leaves multiple tracks in the different layers of the CMS detector.

. Particle accelerators are in use worldwide and are also used to treat tumors.LHC is underground and does not emit any radiation outside. Tullio |

Meet the LHC’s Latest Discovery, the Long-Sought Pentaquark The Large Hadron Collider, the world’s most powerful particle accelerator, has given physicists yet another gift—physical proof of the existence of the pentaquark, a new form of matter that might be created in collapsing stars. |

Not CERN, but particle physics: http://www.sci-news.com/physics/science-weyl-fermion-massless-particle-03037.html The Weyl fermion – an elusive massless particle theorized 85 years ago – has been confirmed by direct observations for the first time. ![]() |

Not CERN, but particle physics: I like that word 'confirmed' :) Thanx for posting this Gary. rOZZ Music Pictures |

Photons also have no mass and their speed in vacuum is the speed limit.So I don't believe that Weyl fermions could go faster than light, but I don't know much about them. They certinly have spin, hence their name, but what about charge? Without any charge, how do you accelerate them? Tullio |

They certinly have spin, hence their name, but what about charge? Without any charge, how do you accelerate them? Maybe the force of other elementary particles gives them a boost? I'm thinking of Newton's first law of motion right now. rOZZ Music Pictures |

They can carry a charge. http://www.livescience.com/51584-weyl-fermions-created-lab.html There is a problem that Newton's laws don't apply in the quantum world. Newton's laws are now seen as an approximation of the theory of relativity, valid at speeds much lower than light and in relatively weak gravitational field. For over fifty years scienctist have been trying to come up with the Theory of Everything. https://en.wikipedia.org/wiki/Theory_of_everything |

Why would there be a difference in how matter interacts on a quantum scale or astronomical scale, one might ask. Energies interact the same all over our Universe? Electrons and protons revolve around the atom in their molecule, just as planets revolve around their star and stars revolve around the black hole at the centre of their milkyway. Sounds like a resemblance in my opinion. rOZZ Music Pictures |

That's odd.. Why would there be a difference in how matter interacts on a quantum scale or astronomical scale, one might ask. Energies interact the same all over our Universe? There are no difference in how matter interacts on a quantum scale or astronomical scale. But so far no theory can explain how it works. Odd is an understatement in the Quantum World. Einstein didn't understand it. Richard Feynman once said something like this to his students "If you think you understand quantum mechanics, you don't understand quantum mechanics." This is probably a paraphrase of the quote attributed to Niels Bohr: "Anyone who is not shocked by quantum theory has not understood it." |

Maybe we have to search more in the field of energies then instead of concentrating on baryonic matter. rOZZ Music Pictures |

The "ability of a system to perform work" is a common description of energy. But you cannot measure energy. Only calculate it when it's a property of objects. Energy has no fields. If so energy could be detected. |

I can now detect some bad human energy in this forum field. |

Quantum mechanics is of no interest to the man in the street. If it can be shown to cure cancer, or bring down taxes then they might show an interest. Other than that it is best left to scientists, geeks, and bored Swedish posters.Don't forget to include Jack of all trades yet master of none. L(i)ke Julie, I tend to favour energy research. When the world runs out of Energy we die. |

Once I wrote a paper just for myself and titled it "The coherent brain". Its main thesis is that the brain is a macroscopic quantum object. I kept the paper in my desk not to be confined to a psychiatric asylum. Then I read a book by prof. Roger Penrose titled "The emperor's new mind" which held the same idea. Encouraged, I sent my paper to prof. Penrose as a hard copy to the Mathematical Department of Oxford University and went skiing for a week. When I returned, I found a letter by Prof. Penrose which said that my paper was "highly interesting" and advised me to read another book of his, titled 'Shadows of the mind". Penrose is a pioneer in the theory of black holes. Tullio |

Other than that it is best left to scientists, geeks, and bored Swedish posters. Dark matter is of no interest to the man in the street! Dark matter is a hypothetical kind of matter that cannot be seen with telescopes but would account for most of the matter in the universe |

Energy is indeed unmeasurable and therefore unrefutable, that is the problem in reality for quantumphysics. Darn shame I'd say.. rOZZ Music Pictures |
