CERN. For the company with the ticker symbol CERN, see Cerner. For the rocket nozzle, see SERN. Coordinates: The European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire), known as CERN (/ˈsɜrn/; French pronunciation: [sɛʁn]; derived from "Conseil Européen pour la Recherche Nucléaire"; see History) is a European research organization that operates the largest particle physics laboratory in the world. Established in 1954, the organization is based in the northwest suburbs of Geneva on the Franco–Swiss border, ( WikiMiniAtlas 46°14′3″N 6°3′19″E / 46.23417°N 6.05528°E / 46.23417; 6.05528) and has 21 European member states. The term CERN is also used to refer to the laboratory, which in 2013 counted 2,513 staff members, and hosted some 12,313 fellows, associates, apprentices as well as visiting scientists and engineers[4] representing 608 universities and research facilities and 113 nationalities.
CERN is also the birthplace of the World Wide Web. CERN Podcast. Inertial frame of reference. All inertial frames are in a state of constant, rectilinear motion with respect to one another; an accelerometer moving with any of them would detect zero acceleration. Measurements in one inertial frame can be converted to measurements in another by a simple transformation (the Galilean transformation in Newtonian physics and the Lorentz transformation in special relativity). In general relativity, in any region small enough for the curvature of spacetime to be negligible, one can find a set of inertial frames that approximately describe that region.[2][3] Physical laws take the same form in all inertial frames.[4] By contrast, in a non-inertial reference frame the laws of physics vary depending on the acceleration of that frame with respect to an inertial frame, and the usual physical forces must be supplemented by fictitious forces.[5][6] For example, a ball dropped towards the ground does not go exactly straight down because the Earth is rotating.
Introduction[edit] Background[edit] Cymatics. Resonance made visible with black seeds on a harpsichord soundboard Cornstarch and water solution under the influence of sine wave vibration Cymatics (from Greek: κῦμα "wave") is the study of visible sound co vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid.[1] Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.
The apparatus employed can be simple, such as the old Chinese spouting bowl, or Chinese singing fountain, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Etymology[edit] History[edit] On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Influences in art[edit] Composer Stuart Mitchell and his father T.J. Influences in engineering[edit] Science videos. The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination.
This is the world of "string theory," a way of describing every force and all matter from an atom to earth, to the end of the galaxies—from the birth of time to its final tick, in a single theory, a "Theory of Everything. " Our guide to this brave new world is Brian Greene, the bestselling author and physicist. BRIAN GREENE (Columbia University): And no matter how many times I come here, I never seem to get used to it. NARRATOR: Can he help us solve the greatest puzzle of modern physics—that our understanding of the universe is based on two sets of laws that don't agree? NARRATOR: Resolving that contradiction eluded even Einstein, who made it his final quest. S. BRIAN GREENE:The atmosphere was electric.
S. S. Is the universe a doughnut? Credit: iStockphoto Someday spacecraft will be powerful enough perhaps to journey at extraordinary speeds, spanning the vast interstellar voids. Our technology might develop until we become a vast, powerful intergalactic society, capable of resolving the deepest quandaries ever known. Only then could we definitely answer what is perhaps the ultimate question: “Is the universe shaped like a doughnut?”
This last question pertains to an idea attributed to Homer and mentioned by guest star Stephen Hawking in an episode of The Simpsons. In the episode, Lisa Simpson joins Springfield’s chapter of the brainy organisation Mensa, which assumes mayoral duties and vows to remake Springfield into a perfect society. The prospect of experiencing a blossoming utopia attracts the attention of the British cosmologist Hawking, who – in his first animated appearance on the show – decides to visit and see it for himself. Geometry, however, cannot be the only influence on the dynamics of the universe. SEEDMAGAZINE.COM.
