In a competition, there are 'a'contestants and 'b' judges, where b>= 3 is an odd integer. Each judge rates each contestant as either "pass" or "fail". Suppose 'k' is a number such that, for any two judges, their ratings coincide for at most 'k' contestants. Prove that (k/a) >= ((b-1)/2b) .

Growing up in an African Nation whereby Science as a whole was studied theorethically. It only takes someone who has serious analytical mind to understand it. (it requires double effort here to study any field of science). Any dream of researching is very dificult to pursue. Whith such environment, How can one make a sucessful career ; that could add value to the world as a whole possible?

If we can travel an infinite distance away from the Earth in one direction, and an infinite distance in the opposite direction, surely until we have a defined limit to the Universe as we know it, the Earth is the in the centre (as we know it). What do you think?

I would not consider myself impressed much by or drawn to any one religion, however some of the evps I have recorded definitely make me believe in some other type of dimension. Check out my evps at www.evpvoices.com if you'd like and please let me know if you believe in other dimensions and explain why you do and what you believe they are like.

A simple solution is welcome.The shell will be at a fixed potential at all pts on its surface, I feel . Then how to reach the solution?
The charge particle is not at the centre and hence symmetry will not be available,but fields should be inside and outside the shell, I suppose. The distance of the ch is x from the centre of the shell x

The Dark Star is a red dwarf which is the Sun's binary. It is currently beyond the asteroid belt, denied by astronomers. It was visible some 4000 years ago, and will eventually return with its planets - which may be inhabited!

I believe that something cannot be made from nothing only from particles smaller than itself. Isn't it more likely that Infinity is an ocean of particles too small for man to identify that come together to form larger and larger matter? I believe that a universe is like everything else in the universe and that it grows by taking in matter from outside.
