moment of inertia | Prashasti | Best thread ever!! |

neutrino oscillation | Redbelly98 | Okay, I have approved the item (sorry about the delay in getting back to this). |

pressure | Thomas Johnson | I always wondered isn`t dark matter similar h*c/λ = (6.626*10^-34)*(3.00*10^8)/(557*10^-9) = 3.57*10^-19 J The energy rate (power) is then (2.9*10^17)*(3.57*10^-19) W = 0.104 W (4 × pi × radius2)∞
So... |

neutrino oscillation | tiny-tim | Hi Redbelly! Thanks for the comments. :smile:
C is just a constant (and (m1.m2) is a row vector).
I think it's obvious that λ1 and λ2 are constants, and I hoped the... |

neutrino oscillation | Redbelly98 | Looking good. I have a couple of comments.
1. In the expression for potential V, I think all the terms should be defined. What is C(m1,m2)? Simply a normalization factor, or... |

Physics Forums Medals | adjacent | You fool,Ya fool |

Physics Forums History | adjacent | Very interesting. My "Ancient forum"
Don't quote me.It's just my imaginary part.
I like this forum.It's like a wonder. |

friction | pratikpatil | what is inertial frame of refrence |

work done | Aterioluwa | I'm so confused guys. the work i know of is just force * distance |

rolling | tiny-tim | Added "Rolling" in ships and aircraft to ext expl. |

capacitor | tiny-tim | corrected equation for energy stored in ext expl |

Physics Forums History | Drakkith | An amazing place to learn real, mainstream science without having to deal with crackpots and trolls or worrying that the answers you're getting aren't correct. I love PF! |

magnetic field | san.k | can we enhance a planet's magnetic field to attract and repel alpha particles like a particle accelerator in outer space to create a planet like the "death star" from star... |

rotating frame | jhae2.718 | I wrote up a post on the kinematic transport theorem (http://www.physicsforums.com/blog.php?b=4622), which is similar in scope to this article. I'm not sure if it should be a separate library article... |

Metric Tensor | Mandelbroth | I can't edit it, but this page bothers me. I think the whole thing should be a subcategory for a metric tensor entry or a separate page, like "Metric Tensor... |

simple Lie algebra | lpetrich | What I describe is evident when one uses the "Cartan-Weyl basis": 10.Cartan-Weyl_basis.pdf (http://www.weizmann.ac.il/home/fnkirson/Alg13/10.Cartan-Weyl_basis.pdf) |

magnetic field | boisebrats | it would seem that if this was so, that all other planets mars, mercury etc. would exhibit the same magnetic field with varying mathematical predictability,. . . |

magnetic field | Velikovsky | Is it a possibility that the earth's magnetic field is a result of it's rotation within the electrical/plasmic field/flux given of by the sun? If the earth were to theoretically... |

simple Lie algebra | amos carine | "The Cartan subalgebra can be used in a fashion analogous to the projected angular momentum in quantum mechanics, with the other elements being analogous to raising and lowering operators."
Is there... |

electric field | Drmarshall | So electric fields, having energy, have inertia
So they "distort space" - whatever "space " is - and "cause gravitational forces (whatever they are). |
