"Pmb" wrote in message
If you had any understanding of the covariant derivative at all then you'd know that made a slip and I readlly meant "That's not the covariant derivative Ken. That's the absolute derivative." I.e. I left out the word "the" which is obvious to everyone. (WaiteDavid137) wrote By saying this, you are still arguing that only the covariant partial derivative is covariant. The covariant total derivative is also a covariant derivative. Saying "the" covariant derivative could actually refer to either one. Well its quite clear that you are unable to understand the difference between a proper name and an adjective. It is the proper name because it is the proper adjective, but at least you're starting to backpeddle on your stance that it is not a covariant derivative! You're unbelievable waite. D/dT is not the "covariant derivative." When are you going to get that through that thick head of yours? Since you seem to like the following relativity related document, why don't you write out here so everyone can see the title of Proposition 8.2 and the formula in the box at the link. http://people.hofstra.edu/faculty/St...s/DiffGeom.pdf It happens the formula for calculating the total covariant derivative of a four-vector with respect to proper time. |

Subject: Covariant vs Absolute Derivative

You seem to think that when somone gets one thing correct then they are correct on everything else. That is another mistake you make all the time when it is to your advantage What he wrote in that box is the derivative along the curve. The derivative along a curve is not the covariant derivative. The author of that document is being careless. And that's a fact. Not an opinion. I didn't say whether or not everything was right. I am saying that he said that right. It is the covariant derivative of the four-vector with respect to proper time. Now meet the challenge, post the title and write the equation. |

The title of the document that I just posted a ling to? The equation for the absolute derivative which you incorrectly call the covariant derivative. The doc is above and is called "Introduction to Differential Geometry & General Relativity," The derivative is the the absolute derivative and is at http://www.geocities.com/physics_wor...grav_force.htm Under the CORRECT name "Absolute Derivative" Quit while you're behind |

The title and equation to the proposition that I clearly stated which you just snipped. You sure are a mentally disturbed person. I told you the author made a mistake. I've e-mailed him. I'll pass the response to this thread. I got a response from a very well known GRist who, like I, said that the author was very careless in saying that. Just like you who are always careless. But fine - the child challenges me to copy one thing to here. I'll give the baby his pacifier. However you refuse to do what you're always challenging me to do. That's why you're a coward. Like MTW and their definition of covariant derivative and derivative along the curve - you're too damn scared to post that definition aren't you weasle? ------------------------------------ Proposition 8.2 (Formula for Covariant Derivative) DX^i/dt = dX^i/dt {i pq} X^p dx^q/dt ------------------------------------ Will I now hear happy gurgling sounds fwom widdle davykins? By the way. I did ask certain experts if you could e-mail them on certain things. They said no. They said they have no time for people who will not learn things like the difference between a general tensor and a Lorentz tensor. I agree with him. [crackpot parroting snipped] Seek help waite |

They said they have no time for people who will not learn things like the difference between a general tensor and a Lorentz tensor. You are a liar. More than likely if you emailed any expert which I doubt they told you that YOU could no longer email them. |
