In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, ...

The purpose of this paper is to gain a better understanding of the structure of undecidable problems in automata theory by investigating the degree of unsolvability of these problems. This is achieved ...

Science ‘Deep Change Theory’ Could Pull Us Out of a Global Climate and Pollution Crisis, Scientists Say A new U.N. report maps a path toward a more sustainable future and challenges society to ...

A Theory on Vance's Motives To European diplomats, none of this is surprising. Vance's views on the alliance predate his time in office.

Then Späth came along. Now, 20 years after she first learned about the problem and more than a decade after she met Cabanes, the two mathematicians have finally completed the proof.

Let’s look at each of these problems. Problem 1. Almost all scientists recognize that we don’t yet understand how the first living organism arose from non-living matter.

The structure tradition has its own problems, which in turn will be carried into the hybrid model of organising. The primary challenges for the structure tradition are: the perceived need for ...

This structure has the same symmetry as modular shapes—regardless of how the thread oscillates. The type of string theory that Borcherds investigated can only be mathematically formulated in 25 ...
