Analytical Definition and 260 Threads

i am now trying to figure out the electro-field around a rectangle waveguide. the refractive index of the waveguide is n1, which is larger than that of the cladding, namely n2, outside. we may regard the waveguide embeded in the cladding material. as following shown, the waveguide...

Could someone help with a way (or method) of how to determine the content of calcium in milk at a high school level.

hi i am writing you from turkey.i am a physics student.it is my 2.year.i have a lesson called analytical mechanics.i want to ask to other physics students that they have a lesson like this or not.if you have can you tell me how can i pass it.it is very hard...

hello everybody, i would like to have an open discussion with everybody here about the analytical model for linear PM generator. recently, new design has focusing on using of TFPM generator for its efficiency and stability. due to that, i think the most suaitable step to take is using the...

If some dude jumps into the ocean from a 10m diving board so that when he makes contact with the water F=-mg + cv^2 where c is some frictional constant, how do I solve for the velocity of the guy as a function of the depth under water? I am able to integrate so that I obtain velocity as a...

Wheel A with diameter x rolling around a fixed wheel B with diameter 2x. How many revolutions about its own axis will wheel A makes in rolling once around wheel B? There is slow & steady addition of Threads in MATHS Forum. So I thought of making it more interactive with some puzzler

How one can find the solution to x^y+y^x=100 Where x,y belong to integers?

The point (1, 0) is on a circle, which center is on the line y = -2x. The line 3x + 4y + 15 = 0 is a tangent to the circle. Find the equation(s) for the circle(s). Thanks,

I was wondering what people thought about the notion of creating a forum for analytical mechanics, i.e. Lagrangian and Hamiltonian dynamics. If not then what forum would you recommend discussing the subject? Thanks
