@Sherry: I added an explanation. Is it possible you have copied the question incorrectly?

comment Proving that a propositional theory of any cardinality has an independent set of axioms
I don't see that the other question is restricted to the countable case; the question itself says nothing about countability. The accepted answer by Carl Mummert only handles the countable case, but there is a comment below it giving a reference for the uncountable case (the Reznikoff paper cited by Rahman M), as well as the English translation. I think this truly is a duplicate.

comment How to randomly select a point from the surface of a unit sphere ?
possible duplicate of Picking random points in the volume of sphere with uniform probability. (Although that question is about sampling uniformly from the ball, most of the answers actually start by sampling from the sphere. In any case, as you note, if you can sample from the ball, then by rescaling you can sample from the sphere.)

comment How to understand the definition of weak convergence of stochastic processes
The point is that Definition 2 makes sense if you replace $\mathbb{R}$ by any other topological space, such as $C([0,\infty))$ with the mentioned topology (do you understand what this topology is?). So you should replace $C_b(\mathbb{R})$ with $C_b(C([0,\infty)))$.

comment Distribution of $\| W_t \|^2_{L^2([0,T])}$
Just wanted to point out that I fixed a mistake in my answer. I think it is correct now, I checked it against some numerical simulations.

comment Distribution of $\| W_t \|^2_{L^2([0,T])}$
It's a bit too large a subject to discuss here, but basically this is the issue faced in making the Feynman path integral rigorous.
