I kept the paper in my desk not to be confined to a psychiatric asylum. That's funny Tullio. Max Tegmark used to do the same when he was a graduant student at KTH photo copying a lot of stuff about parallell universes. http://space.mit.edu/home/tegmark/mathematical.html https://www.facebook.com/pages/Max-Tegmark/461616050561921 |

Latest updates Thank's for the link that also gave me this link :) https://www.kaggle.com/c/flavours-of-physics/data The LHCb experiment will shed light on why we live in a universe that appears to be composed almost entirely of matter, but no antimatter In a machine-learning challenge organised by CERN and Yandex Data Factory (a big data-analytics division of Russia’s leading web search provider Yandex), and hosted by the data-science website Kaggle, LHCb physicists invite you to help them investigate a rare phenomenon in particle physics for the chance to win up to $7000. The phenomenon in question? Charged-lepton flavour violation. In this competition, you are given a list of collision events and their properties. You will then predict whether a τ → 3μ decay happened in this collision. This τ → 3μ is currently assumed by scientists not to happen, and the goal of this competition is to discover τ → 3μ happening more frequently than scientists currently can understand. It is challenging to design a machine learning problem for something you have never observed before. Scientists at CERN developed the following designs to achieve the goal. |

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? well, there aren't...just Quantum physics is too complicated on large scale... other theories work just well on large scale... same as Newton laws do well with explaining a Gravity fields...unless we talk about LS or massive Black holes/Neutron stars, etc... 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? Not exactly true...some energies emanate fields - so we can detect them by their fields! ;) On similar principle we r searching 4 DM... ;) ![]() ![]() non-profit org.

In the July-August issue of CERN Courier there is an article on the SESAME synchrotron radiation source being built in Jordan as an example of Arab-Israeli-Cyprus-Egypt-Iran-Pakistan-Turkey cooperation under the auspices of UNESCO and CERN. Maybe particle accelerators have some usefulness outside of physics. Tullio |

• Building scientific and cultural bridges between neighbouring countries, promoting mutual understanding and tolerance through international cooperation, and fostering a regional community of scientific users who will work together at SESAME. http://www.unesco.org/new/en/natural-sciences/science-technology/basic-sciences/international-basic-sciences-programme/sesame/ |

Why would there be a difference in how matter interacts on a quantum scale or astronomical scale, It's the difference between discrete and continuous; macro and micro. Your automobile and an atom of iron. A magnetic field's effect on a battleship and an electron. |

Could that be why matter and not anti-matter dominates? http://www.nature.com/nature/journal/v524/n7563/full/524008b.html Only subatomic particles with a left-handed spin decay as a result of one of the fundamental forces, confirming that the Universe has a left-hand bias. ![]() |

Could that be why matter and not anti-matter dominates? Once it was a war between matter and anti-matter and because nature is not perfect "our" matter won. That the Universe has a left-hand bias needs to be explained... |

Could that be why matter and not anti-matter dominates? If nothing goes right, go left? We have nothing to fear but fear itself. Apart from pain. And maybe humiliation. And obviously death. And failure. But apart from fear, pain and humiliation, failure and the unknown and death - we have nothing to fear. Who’s with me? |

If you are interested there is a CERN Summer Challenge going on at vLHC@home. But you need to have Virtual Box installed on your system. Tullio |

Could that be why matter and not anti-matter dominates? Hehehe. To make it worse. In the quantum world particles can spin both left and right at the same time. Superposition. |

No, if you measure the spin of a particle it is either one way or another in the case of half integer spin (fermions).A photon can have 4 polarization states since its spin is one. Tullio |

That would mean that is impossible or perhaps useless to build quantum computers. https://en.wikipedia.org/wiki/Quantum_superposition Successful experiments involving superpositions of relatively large (by the standards of quantum physics) objects have been performed.[18] |

The Intelligence Advanced Research Projects Agency (I believe it was called DARPA),USA, has called for researchers in quantum computing to submit projects and ask for money. Evidently they still believe in it. A friend of mine, Giuseppe Castagnoli it still working in this field and may be interested., Once I wrote an article with him and it was published in the Italian edition of MIT's Technology Review in 1996. I believe not much progress has been done since then. Tullio |

New largest number factored on a quantum device is 56,153 :) http://phys.org/news/2014-11-largest-factored-quantum-device.html "We're still a far way from outperforming classical computers," Dattani told Phys.org. "The highest RSA number factored on a classical computer was RSA-768, which has 768 bits, and took two years to compute (from 2007 to 2009)." |

my understanding is that antimatter reacts with equal amounts of matter. If that is true the actual damage is quite small. That may be the case but even a small Atomic explosion will do a lot of damage . There is enough energy in the head of a mach stick to flatten a city and possibly the Earth . E = M C squared ![]() |

A meson is made up from a quark-antiquark pair. How come they do not annihilate? Tullio |

Tullio maybe Quarks are not matter but elemental bits so we see the same thing as what happens in the Qantum world . scale , what happens on our scale does not happen on a Quantum scale , a different set of effects are seen ![]() |
