Latvija, atšķirībā nn Igaunijas, nav CERN dalībvalsts  studenti no Latvijas nevar vasarās tur praktizēties...

  3. CERN: Tim Berbers Lee invented HTTP (WWW) 1990, 1993

  4. CERN LHC An image of one of the first lead-ion collisions seen by the ALICE experiment on 7 November, 2010.

  5. Data visualisation of a particle collision inside the Large Hadron Collider, recorded by the ALICE experiment.

  6. LHC Atlas: search for Higgs bosonGreatest Mysteries: What Causes Gravity? • E=mc2 ; v=g * t ; • "Much of today's research in elementary particle physics focuses on the search for a particle called the Higgs boson. This particle is the one missing piece of our present understanding of the laws of nature, known as the Standard Model. This model describes three types of forces: electromagnetic interactions, strong interactions, which bind atomic nuclei; and the weak nuclear force, which governs beta decay. (The Standard Model does not describe the fourth force, gravity.) • “Over the next 15 years, we should begin to find a real understanding of the origin of mass.” • "Newton thought that gravity's force was instantaneous. Einstein assumed that it moved at the speed of light, but until now, no one had measured it," • General relativity (GR) suggests that gravitation (unlike electromagnetic forces) is a pure geometric effect of curved space-time, not a force of nature that propagates. • Most scientists assume that gravity travels at the speed of light and there exist gravitational waves and gravitational radiation (single positive experemnt in 2003) • I put my last dollar, the Higgs shall not be found, just as Gravity waves in the Einstein sense won't be found. • I agree with you. But all of the public tax money is on one side of the issue! • The Higgs is more like a plumber with duct tape, holding the standard model together

  7. The ‘Standard Model’ of Particle Physics Tested by experiments at CERN & elsewhere Perfect agreement between theory and experiments in all laboratories ProposedbyAbdus Salam, Glashow and Weinberg

  8. Open Questions beyond the Standard Model What is the origin of particle masses? due to a Higgs boson? Why so many flavours of matter particles? What is the dark matter in the Universe? Unification of fundamental forces? Quantum theory of gravity? LHC LHC LHC LHC LHC

  9. Where do the masses come from ? Why do Things Weigh? Newton: Weight proportional toMass Einstein: Energy related toMass Neither explained origin of Mass 0 Are masses due to Higgs boson? (the physicists’ Holy Grail)

  10. Has the Higgs Boson been Discovered? Interesting hints around Mh = 125 GeV ? CMS sees broad enhancement ATLAS prefers 125 GeV
