P/NP?

Back to another Millennium Prize problem! There are two types of questions: one, where an algorithm can solve the question in polynomial time (P), and ones, where there is no way to find the answer quickly, but if information is given on showing what the answer is, it can be quickly verified, which is NP, … Continue reading P/NP?

Poincaré Conjecture… with less detail.

Yes, this was already solved by Grigory Perelman, but I have nothing much, so... Imagine a spherical item. And, for the easiest solution, let's use an apple. Wrap the rubber band around the apple. Without tearing it or letting it leave the surface, we can slowly shrink the rubber band until it becomes a single … Continue reading Poincaré Conjecture… with less detail.
