... Turing in 1936 in order to address Hilbert's Entscheidungsproblem. It is sufficiently simple so that various mathematical theorems can be proven about it. In particular by using this model Turing was able to show that the Entscheidungsproblem must be answered in negative, i.e., there is no mechanica ...

... The fastest algorithm for k-SAT. The best known upper bound for k-SAT is given by the algorithm proposed by Paturi, Pudlák, Saks, and Zane [17, 18]; this algorithm is called PPSZ. This algorithm consists of exponentially many runs of a polynomial-time procedure. This procedure is based on the follo ...

The answer seems to lie with the relationship between the observer and the observed world, a relationship mediated by the fundamental impossibility of measuremen ...

For times not larger than the so-called “Ehrenfest time” C| log ~|, we are able to estimate semiclas ...

Orchestrated objective reduction

Orchestrated objective reduction (Orch-OR) is a hypothesis that consciousness in the brain originates from processes inside neurons, rather than from connections between neurons as in the conventional view. The mechanism is held to be a quantum physics process called objective reduction which is orchestrated by molecular structures called microtubules.The hypothesis, which was put forward in the early 1990s by theoretical physicist Roger Penrose and anaesthesiologist and psychologist Stuart Hameroff, has so far been rejected by the majority of cognitive scientists.
