It is starting to make a little more sense, now that I have a clearer picture of it. I think the flat head is extensive enough that it...

It looks like they are called "Spiral Shank Nails", and the grooves afford superior holding power for the nails: I don't think the...

It could have been explained better, I agree. The magnets in the photo are static magnets and the interpole boundary is the neutral line...

You've got a very odd looking nail. I thought the head of the nail was the magnet. That is the head of the nail as I know it. You...

The pictures were unclear and the OP's explanations were lacking. I think that larger surface with 3 rings is the sensor, but I don't...

Can you draw a diagram of where the poles are on this magnet? I had trouble following your explanations.

I want to repeat something from post 33 for those who might have missed it...

I think I basically did that solving the cubic by linear approximation to first order, where once I got a solution, I could get an...

One can always resort to the Newton-Raphson method to solve ##\mathbf{f}(\mathbf{x}) = \nabla L = 0## by iteration, where each step...

Note: @Gavran 's method (post 15 above) needs a second power form to take the discriminant. @pasmith 's method works in the general...

I'm not sure I would expect it to, because the trajectory it's following is so far from the Moon, as compared with the Apollo missions...

I did find from one article in a google that the expected speed at closest approach would be 3,139 m.p.h. I am lead to believe the...

Did the rocket speed up when moon's gravity became stronger than earth's? There was one website that a friend of mine found that showed...

Yes, this way seems to get the result a little easier. I worked the ## y=4-x^2 ## and ## y=(2x-6)^2 ## problem by this method just...
