A logic road from special relativity to general relativity

open access: yes, 2011
We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we "derive" an axiom system of general relativity in two natural steps. We will also see how the axioms of special relativity transform into those of

Osterwalder-Schrader axioms - Wightman Axioms

open access: yes, 2000
The mathematical axiom systems for quantum field theory grew out of Hilbert's sixth problem, that of stating the problems of quantum theory in precise mathematical terms. There have been several competing mathematical systems of axioms, and here we shall deal with those of A.S. Wightman and of K. Osterwalder and R. Schrader, stated in historical order.

Surface tension enables induced pluripotent stem cell culture in commercially available hardware during spaceflight

open access: yesnpj Microgravity
Low Earth Orbit (LEO) has emerged as a unique environment for evaluating altered stem cell properties in microgravity. LEO has become increasingly accessible for research and development due to progress in private spaceflight.

Axioms for Behavioural Congruence of Single-Pass Instruction Sequences [PDF]

open access: yesScientific Annals of Computer Science, 2017
In program algebra, an algebraic theory of single-pass instruction sequences, three congruences on instruction sequences are paid attention to: instruction sequence congruence, structural congruence, and behavioural congruence.

Dretske on Closure of Knowledge and Its Rereading in Justification Logic [PDF]

open access: yesحکمت و فلسفه, 2020
The K axiom in the logic of knowledge expresses this epistemological approach that knowledge is closed under known implications. For Dretske, for two reasons, the closure of knowledge cannot be tautology: first, the knowledge operator does not penetrate ...

The Essence of Intuitive Set Theory [PDF]

open access: yes, 2001
Intuitive Set Theory (IST) is defined as the theory we get, when we add Axiom of Monotonicity and Axiom of Fusion to Zermelo-Fraenkel set theory. In IST, Continuum Hypothesis is a theorem, Axiom of Choice is a theorem, Skolem paradox does not appear ...
