The Many Interpretations of Quantum Mechanics
What is the ultimate nature of reality?
Are quantum effects constantly carving us into innumerable copies, each copy inhabiting a different version of the universe? Or do all those other worlds pop out of existence as mere might-have-beens? Do our particles surf on quant... | http://www.scientificamerican.com/article/the-many-interpretations-of-quantum-mechanics/ | <urn:uuid:1c48e072-a2a2-4bfe-a098-759d1f240901> | en | 0.926607 | 0.822911 |

Advanced Quantum Mechanics
Fall, 2013
Building on Professor Susskind’s previous Continuing Studies courses on quantum mechanics, this course will explore the various types of quantum systems that occur in nature, from harmonic oscillators to atoms and molecules, photons, and quantum fields. Students will learn what ... | http://theoreticalminimum.com/courses/advanced-quantum-mechanics/2013/fall | <urn:uuid:df63e596-823c-41c6-b463-fdfec34191d9> | en | 0.853126 | 0.709419 |

17 Equations that would change the world - Pythagora's Theorem?
Written By Real Kevin Jay on Friday, July 27, 2012 | 8:34 AM
Few academic subjects evoke as polarized reactions as ‘Mathematics’ does.
It is a dreary chore for most, an inescapabl... | http://philippineinquirer.blogspot.com/2012/07/17-equations-that-would-change-world.html | <urn:uuid:b002ec4a-1f4b-477e-a5ec-3f2710264ba2> | en | 0.966092 | 0.03321 |

Nuclear Magnetic Resonance of Hydrogen Molecules Trapped inside C70 Fullerene Cages
We present a solid-state NMR study of H2 molecules confined inside the cavity of C70 fullerene cages over a wide range of temperatures (300 K to 4 K). The proton NMR spectra are consistent with a model in which the dip... | http://onlinelibrary.wiley.com/doi/10.1002/cphc.201300269/full | <urn:uuid:7163696c-a1cb-4c2e-9e0d-d5c9f9a19f8e> | en | 0.894352 | 0.081537 |

Specifically, if we have a Hamiltonian for a number of interdependent particles, why is solving for the time-independent wavefunction so hard... | http://physics.stackexchange.com/questions/252/the-many-body-problem | <urn:uuid:11a06834-220f-4e89-a4a4-00075012506e> | en | 0.933025 | 0.758632 |
