often, even here it so happens that the most important topics of a subject (that has the crux ) is neglected(by the profs) considering the parameters like time availabilty before a university sem exam, the length and the extent to which it ought to be taught etc., (and ofcourse the extent of the...
yeah! you are absolutely right! MIT courseware (and other elite universities') are so-down-to- the-earth medium to attend a lecture by elite people...yes that'd do alot of help but nevertheless we cant avoid book-reading.. no doubt I owe so much to all those who want to put sources of education...
last sem we had signals and systems.. I had been through a hard time following the books prescribed by my lecturers.. that's basically because of the content and the purpose of it was to prepare a student for an exam..very less (a few bits) general reading is focussed in them..which didn't...
I'm from India...and I'm a UG student doing engineering of *ECommunications* :here imparts with the knowledge of (prerequisites for higher physics) higher calculus (solving DE's of higher orders), complex number theory(complex integrals etc.,), the numerical methods of solving problems, the...
dear yungman ... i just started the Griffiths for EM theory and it is like how i wanted and i'm pretty much satisfied with it..can u suggest books for the other topics (mentioned above) too?
thanks in advance,..
Hi...I'm basically from a low-profile college..and there are not quite many sources to learn in my college even the faculty; I've found PF too good(especially the mentors) and I'm ever so will be grateful to this site..
OK.,
so Ive just entered in my 2nd semester of Electronics and...
best book for "Electromagnetic Theory & Transmission Lines"
We've this subject of "electromagnetic theory and transmission lines" this semester..and i wanted to know which books deal the content properly ...mastering this topic may require that one cool book (and ofcourse, regular effort)...and...
I've just started my [signals and systems] and [electronic devices and circuits] this sem...and i am learning that signals and systems topics are the core and fundamental concepts required for a electronic communication engineer...
though i havent found a great book that covers all the topics...
umm..dimension?? the one that schrodinger's wave equation has to tell is about charge density?! what i feel is that, it is a quantity which we use to describe discrete yet continuous therefore "probabilistic" experience of nature to define THE POSITION (charge density!! :?)
of a particular free...
(
hmm...(probabilty/volume) i wonder how this quantity can take a "non real" value..! how do u think we need to interpret and understand this?? anyone?? please! much appreciated!!
the range of (psi) squared is ??
(psi) of the schrodinger's wave equation is displacement? ( or, what are it's SI units??)
(psi) squared gives the "probability" of finding a particle in space..does this mean that,
0<= ((psi) sqaured) <=1 ??
lol... i was just trying to know that "how mysteriously" can the probability function
psi(x) = a exp(-iw(t-x/v) ) (all symbols have their usual meanings)
be written , which describes the statistical description of particles such as photons, electrons, etc., as a function of time, position...
it could be by the power of Newton's laws and energy conservation principles, one can sort out the equation of a wave classically...
y=a exp(-iw(t-x/v) ) ; ----1.
in the quantum domains where classical situations are ruled out, how is it apt to say or on which basis can we say that...
can you please share any information about comics or anything related in that aspect retaining good humour and quick/clever wittedness....?? thanks alot in advance...
"surely you are joking ,mr feynman" is from my side... please do comment !
please name a descent book for solid state physics of undergradute level..plz..plzz.
hi... i hav just joined my engineering course for electronics... and I desperately need a descent book for solidstate physics to embark on... note that i'm a begginer in Quantum theory..
By "within limits" i mean the limits of corresponding variable by which the integrand is multiplied i.e. the factor by which the integrand is multiplied which is a differential magnitude.... ( eg., limits of "x" if the integrand is multiplied by "dx" and limits of "theta" if the integrand is...
the length of any geometrical arc is given by [ intg of ( (dx .dx +dy.dy)^1/2 ) ] within proper limits... that is according to "pythogorean theorem"..
on simplifying the above thing we get... intg [(1+(dy/dx)^2)^1/2) ].dx
Now, comming to the problem i.e., length of an ellipse...
how is the force due to air resistance acting?? (like in general proportional to displacement or velocity of the particle (instantaneous)) and yes..is the collision between the particle and the air molecules is inelastic?? if so then the mass of the aprticle is increased in due course of...
Mass and charge are qualities of any substance found in nature. That's because they can produce fields of forces. Fields have the capability to do work so we say that energy is stored in fields.but why mass alone is a condensed form of energy as E=MC^2 suggests..why not E=qC^2 ? I mean charge...
dear conor d...,,
"like charges repel and opposite charges attract"
"accelerated charges produce magnetic field besides electric field"
"momentum of any system of particles is conserved if no net force acts on the system"
"total energy of any isolated system is always conserved"...
So, the flaw is there in my question..actually i thought that both positive charges(atomic nuclie) as well as electrons move in a conductor while there is a current in it..there i was wrong..
