Thanks a lot

Gr8 explanation from edgadro! Thanks!

Fine. Thanks all.

Please anyone tell me how laplace transformation is derived. It transform a funtion into new one. Then what we get? Any example to show how it make a function easy to solve?

Yes u have done right thing. I1*1-(I1-I2)=2. I UNDERSTAND. BUT WHEN WE USE KVL, THEN WE CHOOSE A LOOP.THEN WE TRAVEL AROUND THAT LOOP ADD THE VOLTAGE DROPS. WE TAKE PROPER SIGN CONVENTION. THAT IS IF WE TRAVEL IN DIRECTION OF ASSUMED CURRENT THEN WE TAKE VOLTAGE DROP AS NEGATIVE AND VICE...

That means i should write equation=2 volts? But kvl says "the algebric sum of the products of currents and resistances in each of the conductor in any closed path(mesh) in a network plus the algebric sum of the emfs in that path is zero" taking this def. Along the rhombhus path. I don't get...

In this diagram(made at last) if i assume the curren direction as shown, I get 3 equations: 2i-6i1+4i2=0 3i+4i1-9i2=0 5i-3i1-5i2=0 check i1 is i subscript 1.(i don't know how to write subscript). if i put in matrix form( i want to solve via matrix method only). i am getting i=0 i1=0 i2=0...

@passionflower i didn't get ur reply's meaning. What zoe wud see is the clock in jasper's frame ticks at rate T=t/(1-v of zoe wrt jasper^2/c^2)^1/2 where t is zoe's own clock rate(duration of seconds, u can assume) What is (1-v^2)^1/2 ?

OH GENDER MISTAKE. NOT ACCQUAINTED with names. I WAS TALKING ABT ZOE, "DOES(NOT DO) SHE SEE THE DIGI CLOCK TO TICK SLOW?" WAS THAT BECAUSE SHE PERCEIVE CHANGE IN DIGITS SLOWER THAN THEY ARE?? REASON; LIGHT WAVES TAKES ZIG ZAG PATH REACH HER EYES? IT THIS SO?

In the proof of time dilation. Below http://www.phys.unsw.edu.au/einsteinlight/jw/module4_time_dilation.htm I have a doubt in symetry of time dilation. If there's a big lcd screen digital clock in jasper's verandah(at rest wrt ground). And zoe is moving at speed close to c. Do he see that lcd...

Here's a simple proof. http://www.phys.unsw.edu.au/einsteinlight/jw/module4_time_dilation.htm

big big posts. I'll read later(may b) I stay in india. Doing engineering at NIT RKL. (clg ain't good, students are good). I am also very much interested in maths, and want to become mathematician. I'll be contributing to projects u guys make. And would promote my projects too. Projects here i...

yeah may be part wise i wud get. But firstly i need a big "Modern Physics " book that covers as much as whole into modern physics.

Thanks! I got an idea of what books i should buy. Further, i need a complete volume of quantum physics from relativity to wormholes in cosmolgy. Mike ur recomended books seems useful. But i fear if they are too thin. U got my point? I want a full journey of quantum physics?

hello everyone.i need you ppl to recommend a quantum physics or modern physics book for reference.i stay in india. Wiley publication and Pearson Education are two publisher which i knw.u can suggest any other but good ones.
