49ba4d2773931ce0 | Quantum theory is one of our most successful physical theories, but also one of the most mysterious ones: why are detector click probabilities in nature described by abstract mathematical structures like Hilbert spaces, complex numbers, and operators? This question of “why the quantum” has more than just philosophical ... |

In this work we discuss the zero temperature limit of a “p-wave” holographic superconductor. The bulk description consists of a non-Abelian gauge fields minimally coupled to gravity. We numerically construct the zero temperature solution which is the gravity dual of the superconducting ground state of the “p-wave” h... |

1b2934acb2bc5563 | Like information invisibly encoded in strands of DNA, engineered works — bridges, dams, aircraft, disk drives, motors, and so on — are characteristically imprinted with math. With few exceptions, math is the foundation as well as the structure for all technological achievement; and on the wings of computers, it may car... |

Quantum mechanics of a particle
1. Mar 4, 2005 #1
I have a couple things I don't understand:
1. Why is it that the more you conifne a particle, the higher its energy is?
2. Why is it that the more nodes there are in the wavefunction the higher the energy is?
