Computational Complexity Theory studies how difficult it is to solve a problem, or how hard it is to verify that a proposed solution is indeed correct.

|January 23: Testing how weird nature really is|
According to quantum theory, two quantum objects can be "entangled" in a way that only joint properties are sharply defined, while the individual properties of each object are lost. For instance, two "quantum arrows" (spins) can be such that they surely point in opposite directions (sharp joint property) but no arrow points in a definite direction (individual properties are lost). This is clearly at odds with our everyday experience, in which joint properties appear only as consequences of individual ones.
