I have decided to make the presentation on the J meson paper. Thanks!

They are, but making a presentation on those would require a thorough knowledge of the experimental techniques involved. And I have to go into the details of the methods for the presentation. Basically I am on the lookout for theoretical papers.

Hi all! I am a first year BS-MS student and I need to make a presentation on a paper or a review article from a primary reference journal. The broad topic is particle physics. I searched on Physical Review D, Nature and Science but couldn't get anything which was not too mathematical...

Okay. Here it is. Maxwell first defines the basics of line integrals and vector potentials and introduces the del operator. Now, -dψ = Xdx + Ydy + Zdz, where ψ is the vector potential and X, Y and Z are the components of the vector R in the directions of the co-ordinate axes. Now, he writes...

Anyone?

Cyclosis in Maxwell's "Electromagnetism (Vol.1)" On page 16, sec. 18 of his "Treatise on Electricity and Magnetism (Vol. 1)", Maxwell introduces the terms cyclosis and cyclomatic number. I cannot visualize the geometry that he describes and so the next few pages are lost on me. Please help me...

I got it. Thanks a lot!

Are you saying this because on differentiating the second degree equation with respect to time, we have x=7 as a root? On the other hand, differentiating the linear equation x'=x-7 would give us a constant velocity.

I agree with you. But, after all x'=(x-7)2 is an equation in the second degree. I can single out x=7 as special through the equation x=x'-7 too, which is linear, and it violates the homogeneity of space.

Einstein, in his paper "On the Electrodynamics of Moving Bodies", part 1, sec. 3, writes: "Primarily it is clear that on account of the property of homogeneity which we ascribe to time and space, the equations must be linear." What has the homogeneity of space and time to do with the degree of...

Many a times, in papers written on experimental work, there are statements like "there are no first order changes in time, but only those of the second order". What do such statements mean?

This very phenomenon.

Why isn't there a theory on this? I mean, I was "taught" this 7 years ago in primary school, and took it as a fact. This is most certainly an everyday experience. What might be the hurdles in explaining this phenomenon?

Why does paper become translucent when wax, butter or oil is rubbed on it?

I'm looking for a semi-popular book on the Riemann hypotheses, on the scale of Derbyshire's book. It seems that Derbyshire and Edwards are the best in this area. Which one should I go for? The content must be quite extensive. Please suggest other ones too...
