Hi all, I was wondering if anyone of you has read the book of Laurent Nottale Fractal Space-Time and Microphysics: Towards a Theory of Scale Relativity why is not his approach adopted ?- as apparently, he extended the principle of relativity to scales and thus proposes a unifying...

thanks. I still don't see how things work. Any other help ? I have that x=R \cos(\theta) \cos(\phi), \\ y=R \sin(\theta) \cos(\phi), \\ z=R \sin(\phi) and \frac{dr}{dt}=v what am I missing ?. Is \tan(\theta)=\frac{r}{R} ?

thank you for the answer. angles as a function of time. I see how to do it on a circle but on a sphere I don't arrive to visualize the movement. Just to be sure, on a circle of radius R we have that d \theta=\frac{v}{R} dt, so by integrating we have \theta(t)=\frac{v}{R} t + \theta_1 ?

Hi all, I have a question on the movement of a point on a sphere. Consider a point P(\theta,\phi) (\theta and\phi are the latitude and the longitude, respectively)moving from a point P_1(\theta_1,\phi_1) to a point P_2(\theta_2,\phi_2) with a constant speed v. How to find the latitude...

ok, thank you. I did create a web page http://companion-to-analysis.chez.tiscali.fr/ and you can put the file there by ftp Login FTP: book.korner@tiscali.fr Password FTP: bookorner FTP Server: ftp.chez.tiscali.fr

Also, can anyone send me the file of the book by email or indicate by PM the address of a website where I can find it. I am interested, but I don't understand what you mean by this ? I did send you a PM try www.tiscali.fr

thank you. is this book suitable for self study as the title suggests "A Second First and First Second Course" having a certain basis, no ?

Hello, is this a book from where one can start studying analysis or is it necessary to have some prerequisites ? is it a book for undergraduate or graduate students ? thanks
