    Present at the Creation: Discovering the Higgs Boson , Hörbuch, Digital, ungekürzt, 503min
    The Large Hadron Collider is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013. Its superconducting magnets guide two beams of protons in opposite directions around the track. After accelerating the beams to 99.9999991 percent of the speed of light, it collides the protons head-on, annihilating them in a flash of energy sufficient to coalesce into a shower of particles and phenomena that have not existed since the first moments of creation. Within the LHC’s detectors, scientists hope to see empirical confirmation of key theories in physics and cosmology. In telling the story of what is perhaps the most anticipated experiment in the history of science, Amir D. Aczel takes us inside the control rooms at CERN at key moments when an international team of top researchers begins to discover whether this multibillion-euro investment will fulfill its spectacular promise. Through the eyes and words of the men and women who conceived and built CERN and the LHC, Aczel enriches all of us with a firm grounding in the scientific concepts we will need to appreciate the discoveries that will almost certainly spring forth when the full power of this great machine is finally unleashed. With Present at the Creation, we can all follow the progress of an experiment that promises to greatly satisfy the curiosity of anyone who ever concurred with Einstein when he said, “I want to know God’s thoughts - the rest is details.” ungekürzt.

    Skyrmions - A Theory of Nuclei
    Skyrmions - A Theory of Nuclei surveys 60 years of research into the brilliant and imaginative idea of Tony Skyrme that atomic nuclei can be modelled as Skyrmions, topologically stable states in an effective quantum field theory of pions. Skyrme theory emerges as a low-energy approximation to the more fundamental theory of quarks and gluons - quantum chromodynamics (QCD). Skyrmions give spatial structure to the protons and neutrons inside nuclei, and capture the interactions of these basic particles, allowing them to partially merge. Skyrme theory also gives a topological explanation for the conservation of baryon number, a fundamental principle of physics. The book summarises the particle and field theory background, then presents Skyrme field theory together with the mathematics needed to understand it. Many beautiful and surprisingly symmetric Skyrmions are described and illustrated in colour. Quantized Skyrmion motion models the momentum, energy and spin of nuclei, and also their isospin, the quantum number distinguishing protons and neutrons. Skyrmion vibrations also need to be quantized, and the book reviews how the complicated energy spectra of several nuclei, including Carbon-12 and Oxygen-16, are accurately modelled by rotational/vibrational states of Skyrmions. A later chapter explores variants of Skyrme theory, incorporating mesons heavier than pions, and extending the basic theory to include particles like kaons that contain strange quarks. The final chapter introduces the Sakai-Sugimoto model, which relates Skyrmions to gauge theory instantons in a higher-dimensional framework inspired by string theory.

    Bis(s) ins Innere des Protons
    Jetzt in zweiter überarbeiteter und aktualisierter Auflage!"Bei vielen seiner witzigen Ideen, Physik humorvoll zu erklären, war ich echt sauer. Ich dachte mir: Warum zum Teufel bin ich da nicht drauf gekommen ..."Vince Ebert, Diplomphysiker und KomikerGeben Sie's zu, wir alle fragen gerne mal: "Was ist da drin?" - und einige, die hören mit dem Fragen einfach nicht mehr auf. Sie haken nach, bis es als Antwort nur noch gibt: "Das war's, kleiner geht's nicht mehr."Da wo's klein wird, wird die Welt plötzlich ganz verrückt: Aus purer Energie werden Teilchen erzeugt. Materieteilchen bekommen Geschwister aus Antimaterie. Teilchen, die es eigentlich gar nicht geben dürfte, entstehen plötzlich aus dem Nichts. Die Natur leiht sich Energie, die eigentlich gar nicht da ist. Kräfte verhalten sich völlig anders als alles, was wir aus dem Alltag kennen. Das ist die Welt der Teilchenphysik.Teilchenphysiker bauen die größten Experimente aller Zeiten, um die kleinsten Teilchen des Universums zu untersuchen. Sie gehen an die Grenzen des technisch Machbaren und arbeiten dabei über Landesgrenzen hinweg zusammen.Wer das alles auch so spannend findet wie die Teilchenphysiker selbst, ist herzlich eingeladen, dieses Buch zu lesen. Wer glaubt, dass man davon ohne ein Studium in der Teilchenphysik nichts versteht, der auch. Quantenfeldtheorien, Teilchenbeschleuniger, Higgs-Mechanismus und Co. werden hier nämlich statt durch fiese Formeln mit Hilfe von Affen, Enten, Igeln, Bibern und anschaulichen Bildern erklärt. Okay, die fiesen Formeln gibt's auch ab und zu -aber in Kästen, für die, die's wissen wollen. Und mit Hilfe von verlinkten Videos kann man dann auch noch direkt eintauchen in die Welt des CERN, des Teilchenbeschleunigers LHC und des ATLAS Experiments. Viel Spaß dabei!

    Aurora Borealis: Science & Nature , Hörbuch, Digital, ungekürzt, 7min
    Learn about the science of the Aurora Borealis with iMinds insightful audio knowledge series. The aurora borealis, often referred to as the Northern Lights, is a natural light-show that appears in the sky around the north magnetic pole. Auroras can sometimes be seen in other places of the world, but not as clearly. In the southern hemisphere, the phenomenon is called “aurora australis”. The aurora borealis occurs because of an interaction between solar wind and the Earth’s magnetic field. When the sun’s gases explode, some of the particles are blown away in a phenomenon known as solar wind. The particles in the solar wind travel at speeds of over 600,000 miles per hour and take two to three days to reach the Earth. When these particles reach the Earth, some of the electrons and protons get caught in the Earth’s magnetic field. This happens most frequently in the Polar Regions of the Earth where the magnetic field is stronger. The electrons and protons get trapped in the atmosphere, and move in a giant oval shaped motion. Perfect to listen to while commuting, exercising, shopping or cleaning the house.. iMinds brings knowledge to your MP3 with 8 minute information segments to whet your mental appetite and broaden your mind. iMinds offers 12 main categories; become a Generalist by increasing your knowledge of Business, Politics, People, History, Pop Culture, Mystery, Crime, Culture, Religion, Concepts, Science and Sport.

    It Started with a Wedding (MP3-Download)
    Alfie McCreadie wants his twin sister Nessa to have the best wedding ever, but he's not happy at being roped in as wedding planner – especially as, unbelievably, his main assistant seems to be Nessa's cat, Schubert. Anyway, Alfie is a scientist. He might know his protons from his neutrons, but what does he know about weddings? It's Nessa who points him in the direction of Bea's Garden, just outside Edinburgh, where he's tasked with picking a 'very-relevant-bouquet'. It's there he meets Fae Brimham, who might be prettier than any bouquet bloom but doesn't seem impressed by Alfie's sensible, scientific side. But when Nessa and Schubert are involved, surprises are bound to happen and, despite less-than-perfect first impressions, perhaps something new and beautiful can still blossom for Alfie and Fae…

    The Sun: The Gabriel Ramirez Series, Book 72 , Hörbuch, Digital, ungekürzt, 55min
    Interesting fact, the sun is terrible at fusion. Think about it, why hasn't the sun just instantly ignited all its fuel, and blow up all the milky way? The limiting factor infusion for the sun is one, heat, and two beta decays. The first you likely knew, but beta decay, "whatchu talking about Willis?" I'm quoting Arnold from one of my favorites shows growing up called Different Strokes. Well, when you smash two hydrogen atoms together, you get what we call a di-proton. It is sometimes called Helium-two, and boy does it not like existing. Due to the fundamental properties of atomic and subatomic particles, he-two is unstable. Most times, like nearly every time he-two created, the protons break back apart into hydrogen atoms, the party just stops. ungekürzt. Language: English. Narrator: Rachel Q. Haines.

    Why Science Does Not Disprove God , Hörbuch, Digital, ungekürzt, 412min
    The renowned science writer, mathematician, and best-selling author of Fermat's Last Theorem masterfully refutes the overreaching claims of the "New Atheists," providing millions of educated believers with a clear, engaging explanation of what science really says, how there's still much space for the Divine in the universe, and why faith in both God and empirical science are not mutually exclusive. A highly publicized coterie of scientists and thinkers, including Richard Dawkins, the late Christopher Hitchens, and Lawrence Krauss, have vehemently contended that breakthroughs in modern science have disproven the existence of God, asserting that we must accept that the creation of the universe came out of nothing, that religion is evil, that evolution fully explains the dazzling complexity of life, and more. In this much-needed audiobook, science journalist Amir Aczel profoundly disagrees and conclusively demonstrates that science has not, as yet, provided any definitive proof refuting the existence of God. Why Science Does Not Disprove God is his brilliant and incisive analyses of the theories and findings of such titans as Albert Einstein, Roger Penrose, Alan Guth, and Charles Darwin, all of whose major breakthroughs leave open the possibility - and even the strong likelihood - of a Creator. Bolstering his argument, Aczel lucidly discourses on arcane aspects of physics to reveal how quantum theory, the anthropic principle, the fine-tuned dance of protons and quarks, the existence of anti-matter, and the theory of parallel universes, also fail to disprove God. ungekürzt.
