One day in 1900, German physicist Max Planck told his son that he had made a breakthrough as important as Isaac Newton’s discovery of the workings of the universe. Planck had reached the surprising conclusion that light behaves as if it is packaged in discrete amounts, or quanta, a seemingly simple observation that would lead to a powerful new field of physics called quantum mechanics.
In the following decades, a series of great physicists built on Planck’s discovery, including Albert Einstein, Niels Bohr, Louis de Broglie, Werner Heisenberg, Erwin Schrödinger, Richard Feynman, and many others, developing quantum mechanics into the most successful physical theory ever devised—the general framework that underlies our understanding of nature at its most fundamental level.
Quantum mechanics gives us a picture of the world that is so radically counterintuitive that it has changed our perspective on reality itself, raising profound questions about concepts such as cause and effect, measurement, and information. Despite its seemingly mysterious nature, quantum mechanics has a broad range of applications in fields such as chemistry, computer science, and cryptography. It also plays an important role in the development and innovation of some of today’s most amazing—and important—technologies, including lasers, transistors, microscopes, semiconductors, and computer chips.
Quantum Mechanics: The Physics of the Microscopic World gives you the logical tools to grasp the paradoxes and astonishing insights of quantum mechanics in 24 half-hour lectures designed specifically for nonscientists and taught by award-winning Professor Benjamin Schumacher of Kenyon College.
No comparable presentation of this subject is so deep, so challenging, and yet accessible. Quantum Mechanics is generously illustrated with diagrams, demonstrations, and experiments and is taught by a professor who is both a riveting lecturer and a pioneer in the field, for Professor Schumacher is an innovator in the exciting new discipline of quantum information.
Think Like a Physicist
Working on the principle that any discovery made by the human mind can be explained in its essentials to the curious learner, Professor Schumacher teaches you how to reason like a physicist in working out the features of the quantum world. After taking this course, the following apparently inexplicable phenomena will make sense to you as logical outcomes of quantum processes:
That quantum particles travel through space in the form of waves that spread out and are in many places at the same time
That quantum mechanics takes us to a bedrock level of reality where objects are utterly simple, identical in every respect
That two quantum particles can interact at a distance in a way that seems almost telepathic—a phenomenon that Albert Einstein called „spooky“
That even in the complete vacuum of empty space, there is still a vast amount of energy bubbling into and out of existence
Regarding the last phenomenon, you could say that quantum mechanics not only changes our view of everything, it also changes our view of „nothing!“
Quantum Puzzles
Consider these quantum puzzles that have striking philosophical implications:
Schrödinger’s cat: Erwin Schrödinger noted that the standard Copenhagen interpretation of quantum mechanics makes it possible for a cat to be considered simultaneously dead and alive when exposed to a potentially lethal quantum situation.
Bell’s theorem: John Bell showed that we must either give up the idea that particles have definite properties before they are measured, or we must imagine that all the particles in the universe are connected by a web of instantaneous communication links.
Many-worlds interpretation: In a scenario adopted by many science fiction authors, Hugh Everett III argued that every possible outcome of every quantum event takes place in a limitless branching series of parallel universes—of which we see only one.
Clear, Enlightening, and Thorough
Quantum Mechanics begins by exploring the origin of quantum mechanics and its golden age of discoveries in

Welt der Physik: Wie Gletscher gleiten

Veröffentlicht

Durch


Mit zunehmender Erderwärmung gleiten Gletscher immer schneller vom Festland der Antarktis oder von Grönland ins Meer. Geschmolzen sind die gigantischen Eismassen wesentlich für den Anstieg des Meeresspiegels verantwortlich. Forschern gelang es nun, das Verhalten gleitender Gletscher abhängig vom Untergrund genauer zu erfassen. Wie sie in der Fachzeitschrift „Science“ berichten, könnte ihr universelles Gesetz zu besseren Modellen für das Abschmelzen der Gletscher und den darauffolgenden Meeresspiegelanstieg führen.

Da sich die oftmals Hunderte Meter dicken Gletscher in der Antarktis oder auf Grönland nur sehr schwierig untersuchen lassen, haben Lucas Zoet und Neal Iverson von der Iowa State University in Ames das Verhalten von Gletschern nun im Labor nachgestellt. In einem speziellen Kühlschrank ließen sie Eisstücke auf einer verformbaren Unterlage aus Sand und Geröll – analog zum Untergrund der Antarktis – gefrieren. Auf diese Eisstücke übten sie mit einer Hydraulikpresse sehr hohe Drücke aus, die der tonnenschweren Belastung von echten Gletschern entsprechen sollten. Die Eisstücke bewegten sie anschließend mit einem Motor über die Geröllschicht – mit typischen Geschwindigkeiten von bis zu 500 Metern pro Jahr.

Die Experimente zeigten den komplexen Zusammenhang zwischen hohem Druck, verformbarer Unterlage und Reibung. Glitt der Gletscher sehr langsam, verformte sich der Untergrund unter dem hohen Druck und es bildeten sich unter dem Gletscher stationäre, mit Wasser gefüllte Hohlräume. Mit zunehmender Geschwindigkeit bewegten sich – zusätzlich zur Verformung des Untergrunds – auch die kleinen Wasserspeicher und erleichterten so als Schmiermittel das Gleiten des Gletschers. Den Wechsel zwischen diesem Gleitverhalten beobachteten die Forscher auch für verschiedene Unterlagen, die teilweise weicher als Sand, mal fester als Stein waren.

Auf Grundlage ihrer Messungen entwickelten Zoet und Iverson nun ein universelles Gesetz. Es zeigte sich, dass bisherige Gletschermodelle das Tempo der gleitenden Gletscher eher unterschätzten. „Gletschermodelle, die auf unserem neuen Gesetz aufbauen, könnten einen größeren Gletscherschwund in die Meere und damit schnellere Raten für den Anstieg des Meeresspiegels vorhersagen als bisher genutzte Modelle“, sagt Iverson. Mit dem neuen Gesetz könnten die angepassten Gletschermodelle somit die natürlichen Bedingungen besser nachbilden.
