Physics for the 21st Century Course Overview Welcome to Physics for the 21st Century: an on-line course that explores the frontiers of physics. The 11 units, accompanied by videos, interactive simulations, and a comprehensive Facilitator's Guide, work together to present an overview of key areas of rapidly-advancing knowledge in the field, arranged from the sub-atomic scale to the cosmological. The goal is to make the frontiers of physics accessible to anyone with an inquisitive mind who wants to experience the excitement, probe the mystery, and understand the human aspects of modern physics.

Film produced by: Jos Leys (Graphics and animations) Étienne Ghys (Scenario and mathematics) Aurélien Alvarez (Realisation and post-production) Introduction to quantum mechanics Many aspects of quantum mechanics are counterintuitive[3] and can seem paradoxical, because they describe behavior quite different from that seen at larger length scales. In the words of quantum physicist Richard Feynman, quantum mechanics deals with "nature as She is – absurd".[4] For example, the uncertainty principle of quantum mechanics means that the more closely one pins down one measurement (such as the position of a particle), the less accurate another measurement pertaining to the same particle (such as its momentum) must become. The first quantum theory: Max Planck and black-body radiation[edit] Hot metalwork. The yellow-orange glow is the visible part of the thermal radiation emitted due to the high temperature. Thermal radiation is electromagnetic radiation emitted from the surface of an object due to the object's internal energy. Predictions of the amount of thermal radiation of different frequencies emitted by a body. Photons: the quantisation of light[edit] show Spin[edit] .

The Everett Interpretation This FAQ shows how quantum paradoxes are resolved by the "many-worlds" interpretation or metatheory of quantum mechanics. This FAQ does not seek to that the many-worlds interpretation is the "correct" quantum metatheory, merely to correct some of the common errors and misinformation on the subject floating around. As a physics undergraduate I was struck by the misconceptions of my tutors about many-worlds, despite that it seemed to resolve all the paradoxes of quantum theory . The objections raised to many-worlds were either patently misguided or beyond my ability to assess at the time , which made me suspect (confirmed during my graduate QFT studies) that the more sophisticated rebuttals were also invalid. I hope this FAQ will save other investigators from being lead astray by authoritative statements from mentors. I have attempted, in the answers, to translate the precise mathematics of quantum theory into woolly and ambiguous English - I would appreciate any corrections. 4) [M].

10 Ways I Use Technology to Learn Talking to smart people at Startup Weekend SFO During the NYTimes conference this week a tweeter got frustrated with the old white men on the stage, “One last time: Would the panel mind talking about how they themselves use technology to learn?” So I thought I’d respond. Write a blog worth sharing with the world every day (or at least a couple a week). Try to figure out what you learned today. Try to explain how the world works.Find or create a focus for learning. My learning with technology strategy isn’t very high tech: word processing, blog, search, email, social networking, and a spreadsheet.

And the Winner is... Many-Worlds! This is one of several shortened indices into the Quantum Physics Sequence. Macroscopic quantum superpositions, a.k.a. the "many-worlds interpretation" or MWI, was proposed in 1957 and brought to the general attention of the scientific community in 1970. Ever since, MWI has steadily gained in popularity. When a theory is slowly persuading scientists despite all academic inertia, and more and more graduate students grow up familiar with it, at what point should one go ahead and declare a temporary winner pending new evidence? Reading through the referenced posts will give you a very basic introduction to quantum mechanics - algebra is involved, but no calculus - by which you may nonetheless gain an understanding sufficient to see, and not just be told, that the modern case for many-worlds has become overwhelming. Quantum Explanations: Quantum mechanics doesn't deserve its fearsome reputation.
