Bosko replied to the thread A Understanding the Gravitational Redshift Caused by a Black Hole.I suggest you start with the formula for wavelength for an observer at infinity. $$\frac { \lambda_\infty} {\lambda_e} = \sqrt { 1-... -
Bosko replied to the thread I Missing proof of the Shell theorem in General Relativity.How then? Is there a point mass?

Bosko reacted to PeterDonis's post in the thread I Missing proof of the Shell theorem in General Relativity with
Skeptical.
No, it isn't. That's not how the Schwarzschild solution is derived. -
Bosko posted the thread I Missing proof of the Shell theorem in General Relativity in Special and General Relativity.In the classical Newtonian theory of gravity, the shell theorem holds. ( https://en.wikipedia.org/wiki/Shell_theorem ) In the...

Bosko reacted to Office_Shredder's post in the thread A linear programming, polyhedron and extreme points with
Like.
It's trivial that you can get two points to be linearly dependent. For example the square with vertices (0,0), (0,1), (1,0) and (1,1)... -
Bosko replied to the thread A linear programming, polyhedron and extreme points.As an example you can consider a triangle in the plane R^2 with vertices A=(0,1) B=(1,0) C=(1,1) x<=1 y<=1 x+y>=1 ( -x-y<=-1 )
