    This upper limit is wrong I need a help

    Hi adriank I am grateful for your help really there is no connection with the triangle inequality I can set the last two terms of (A-3) equation to constant a and b respectively hence using the 2ab < a^2 + b^2 relation I can obtain the upper limit: |\lambda_{1}||\lambda_{2}| . [...

    This upper limit is wrong I need a help

    this upper limit is wrong...! I need a help I have some concerns about this text: it can easily be shown that F satisfies all the criteria of a vector space. As an example, we demostrate that if \psi_{1}(r) and \psi_{2}(r) \in F both can be cosidered to be complex functions...

    Structure of the wave function space F

    On my last comment referred to the space functions F we have the |\psi(r)|2 expanded expression given by (A-3) The last two terms of (A-3) have the same modulus, which has as an upper limit: |\lambda1||\lambda2|[|\psi1(r)|2 + \psi2(r)|2] Its OK, tha last two terms have the same modulus...

    Structure of the wave function space F

    I have some concerns about Structure of the wave function space F I am referring to chapter II of QUANTUM MECHANICS OF Cohen-Tannoudji The item A-1.a of this chapter say: It can easily be shown that F satisfies all the criteria of a vector space. As an example, we demostrate that if \psi1(r)...

    Formic acid and glycerin as dielectric substances

    like an electrolytic capacitor, no really. I´m working with very high dc voltage 50-60 KV at least the problem is to store this amount of energy in a relatively small device without lost certainly this is a technical challenge.

    Formic acid and glycerin as dielectric substances

    I have thought to do a complete catalog with the values of many compounds. of course, the idea is to use after these values to industrial development the physical condition should be following: -applied frequency null (dc-voltage) -room temperature -normal atmosphere pressure (760mm Hg)...

    Formic acid and glycerin as dielectric substances

    Ok this solution is an organic acid, belong to carboxylic acid group I suppose that its electrical properties are similar to components in this group. Sure the breakdown voltage of it depends on the frequency its value falls with it.

    Formic acid and glycerin as dielectric substances

    Hello everybody I have tried to obtain but I have not been successful the dielectric strength or breakdown voltage values of following materials... these are: FORMIC ACID and GLYCERIN. (to room temperature) I need to know these values... thank you again. Norbert

    Four-vectors, Minkowsky spacetime.

    somebody know about this terms: "timelike, spacelike or lightlike" they often are used in relativistic electrodynamic i.e when I´m referring to the lightcone in a spacetime diagram. I would like some physics-interpretation of this concepts. thanks. D. Norbert
