We prove that by showing that for any set C not of PA-degree and any set A, there exists an infinite subset G of A or such that G ⊕ C is also not of PA-degree.
Medium density fiberboard (MDF) is an engineered wood product that has density and specific gravity similar to solid wood, ranging from 600 to 800 kg/m3 of density and 0.6 to 0.8 of specific gravity. This makes MDF suitable to partially... more

A selection of humorous epitaphs of many mathematicians and physicists of yesteryear
The author contends that a number of steps should be taken if we want to honestly upgrade the thinking instruments of a person, in particular of the Filipino. Since logical reasoning is contextually rooted in everyday discourse, it is... more

It is the proof of De Morgan's laws made in Fitch notation for students of logic lecture.
The aim of the paper is show that that W. V. O. Quine's animadversions against modal logic did not get the same attention that is considered to be the case nowadays. The community of logicians focused solely on the technical aspects of C.... more
Brouwer's views on the foundations of mathematics have inspired the study of intuitionistic logic, including the study of the intuitionistic propositional calculus and its extensions. The theory of these systems has become an independent... more
The paper addresses the abundance of imperfections in Nature and Society, i.e., Reality. Imperfections are encountered in all Sciences and the Arts, models of what this author refers to as Virtual Realities. They are specifically recorded... more
In broad overview, dunes are rounded, elliptical, parabolic or crescentic mounds of loose sand, which have been piled up by wind action in the areas of lakes, (lacustrine dunes), rivers, sea coasts and deserts. There are 5 or 6... more
The traditional conflict in epistemology has been between rationalism and empiricism. Philosophers have often tried to align themselves in one of these schools even though a close reading of some of their writings may suggest they may... more
Adapting a term coined by Ian Hacking, this essay analyzes certain of the styles of reasoning that appear in two novels, Fyodor Dostoevsky’s _Zapiski iz podpol’ya_ (Notes from Underground, 1864) and Natsume Sōseki’s _Kokoro_ (1914). The... more
This is the short project on checking well-formed formula in symbolic logic using Markov Algorithms. In this presentation, I also speak about Reverse Polish Notation: we need to convert our well-formed formula into RPN.
В предлагаемой книге предпринята попытка общедоступного изложения современной логики. Содержание работы затрагивает наиболее актуальные вопросы математической, вероятностной и неформальной логики трех доминирующих разделов современного... more

This article looks at Propositional Logic, also called Statement Calculus, from a combinatorial and algebraic point of view, its implementation in software, and its application to digital electronics. An historical section covers the... more
Symbolic logic faced great difficulties in its early stage of development in order to acquire recognition of its utility for the needs of science and society. The aim of this paper is to discuss an early attempt by the British logician... more
This 8-page long paper addresses the Linguistic implications of two Latin expressions, involving temporal sequencing regarding structures, objects and events, for Set Theory, Topology and Symbolic Logic in view of fuzziness and fluidity,... more
An upper-level symbolic logic course aimed at students who have had little to no formal logic training.
ÖZ Formel mantık alanında Venn şemalarıyla kıyasların geçerlilik denetlemelerinde bazı güçlükler doğmaktadır. Venn şemalarıyla güçlü geçerli kıyasların anlaşılması ve belirlenmesi gayet kolayken, zayıf geçerli olduğu durumlar ile geçersiz... more
Contemporary orthodoxy affirms that singular terms cannot be predicates and that, therefore, ‘is’ is ambiguous as between predication and identity. Recent attempts to treat names as predicates do not challenge this orthodoxy. The... more
