I have a problem... Can you help me ?... :confused: I need to calculate the n-derivative of a function of z (complex number)... n derivative of complex function of a complex variable Thanks, fellows ! Looker

Thank you ! I saw the sites and the books are very useful to me ! And a good book with exercises (and solutions...ops :biggrin: ) ? regards, Looker

I need your help, fellows ! I need the title and author of a good book on PDE. And also a good book with exercises on PDE. Can you help me, please ? :cry: regards Looker

Dear SelfAdjoint ! I didn't study QM in old books, as you name it... My first "Bible" in QM was Mécanique Quantique, by Cohen-Tannoudji and others ! But it didn't stop me to learn things about the beginning of QM. [My first QM teacher was (when he was younger), a collaborator of Louis de...

Hi jhirlo ! Complementarity Principle is, for exemple, the wave-particle duality : in some experiences we detec particles (an electron, for exemple), in other experiences the same electrons have a ondulatory behaviour (they are waves). Other exemple of complementarity : the better we know...

Dear SelfAdjoint, I'm sorry but I don't agree with you ! This is only one of the ways to derive the uncertainty relations... I recommend you to learn the Bohr's method ! Niels Bohr derive Heisenberg's uncertainty relations as a direct consequence of Fourier non local analysis ! And...

oops...! I forgot the link in my previous post !... Sorry ! What I think... Heisenberg's relations are a consequence of the type of waves that Quantum Mechanics uses (plane monocromatic waves and Fourier analysis are the basis of QM ). The link I intended to put in my previous post...

Hello, everybody ! I'm new in this forum (I discovered it by chance, while I was looking for pages on wormholes...Well I didn't find what I wanted but, at least, I discovered this very interesting forum ! ). See, if you want, that link (of a book)... Heisenberg's uncertainty relations...
