Do You Know What Time It Is?
Part of the Series: Horizon
Time gives rhythm to the world around us. But how do we really know what time it is? Professor Brian Cox goes in search of the answer to a question you wouldn't give a passing thought. CERN physicist Professor Brian Cox unlocks the secrets of time in this entertaining programme.…
Atoms
Drawing on what you now know about quantum mechanics, analyze how atoms work, discovering that the electron is not a point particle but behaves like a probability cloud. Investigate the exclusion principle, and learn how quantum mechanics explains the periodic table of elements and the principle behind lasers.
Quantum Mechanics
In 1926 Erwin Schrodinger developed an equation that underlies much of our modern quantum-mechanical description of physical reality. Solve a simple problem with the Schrodinger equation. Then learn how the merger of quantum mechanics and special relativity led to the discovery of antimatter.
Time in Quantum Mechanics
Quantum mechanics is the most precise theory ever invented, yet it leads to startling interpretations of the nature of reality. Probe a quantum state called the collapse of the wave function that may underlie the arrow of time. Are the indications that it shows irreversibility real or only illusory?
A New Theory of Matter
Episode 3 of The Nature of Matter
Discover how the idea that light comes in discrete packets called "quanta" led to a startling new theory of matter: quantum mechanics. One prediction is that matter, like light, behaves as both a particle and a wave, a property observed in subatomic particles such as electrons.
The Geometry of Braids—Curious Applications
Episode 33 of Geometry
Wander through the crazy, counterintuitive world of rotations. Use a teacup and string to explore how the mathematics of geometry can describe an interesting result in quantum mechanics.
The Higgs Boson and Beyond Course
The discovery of the Higgs boson is a triumph of modern physics. The hunt for the Higgs was the subject of wide media attention due to the cost of the project, the complexity of the experiment, and the importance of its result. And, when it was announced with great fanfare…
The Science of Information - From Language to Black Holes
The science of information is the most influential, yet perhaps least appreciated field in science today. Never before in history have we been able to acquire, record, communicate, and use information in so many different forms. Never before have we had access to such vast quantities of data of every…
Quantum Field Theory
Toss out the textbook image of electrons circling an atom's nucleus. This lecture explores the big twist of quantum field theory: The world isn't really made of particles. They're fascinating and necessary figments of quantum mechanics created by observing the fields that fill every inch of the universe, and grasping…
Quantum Mechanics
Episode 8 of Redefining Reality
Delve into the paradoxical subject of quantum mechanics, which was pioneered by scientists probing atomic structure in the early 20th century. Learn about Max Planck, Niels Bohr, Werner Heisenberg, and Erwin Schrodinger. Focus on the Heisenberg uncertainty principle and the strange behavior of the Schrodinger wave function.
Physics and Our Universe: How It All Works Series
Physics is the fundamental science. It explains how the universe works! All you need to begin exploring physics is a grasp of high-school algebra. These lessons are intensively illustrated with diagrams, animations, graphs, and other engaging visual aids and introduce you Newtonian mechanics, oscillations and waves, thermodynamics, electricity and magnetism,…
Space-Time and Mass-Energy
In relativity theory, contrary to popular views, reality is what's not relative: that is, what doesn't depend on one's frame of reference. See how space and time constitute one such pair, merging into a four-dimensional space-time. Mass and energy similarly join, related by Einstein's famous E = mc2.
