Predicting COVID-19 using 'fuzzy logic'

There is increasing pressure on society to test people in a timely manner for infection by the COVID-19 virus, SARS-CoV-2, but physical testing takes time and effort and requires people to either have a test kit at home or ...

Scientists develop novel DNA logic circuits

Based on the complementary base pairing rules, a variety of complex secondary structures can be designed and assembled to develop DNA molecular devices with specific functions which play an important role in diverse research ...

A new piece of the quantum computing puzzle

Research from the McKelvey School of Engineering at Washington University in St. Louis has found a missing piece in the puzzle of optical quantum computing.

A future of helpful engineered 'living' machines?

Engineered, autonomous machines combined with artificial intelligence have long been a staple of science fiction, and often in the role of villain like the Cylons in the "Battlestar Galactica" reboot, creatures composed of ...

The truth about Christ lies in contradiction, philosopher finds

While the quest to explain how Christ can be both fully human and fully divine enjoys a long, fascinating history, Jc Beall, the O'Neill Family Professor of Philosophy at the University of Notre Dame, believes that the quest ...

How to blackmail your family

Raising kids can be tough, and sometimes you need all the help you can get. Biologists at the University of Bristol argue that some animals might be able to blackmail reluctant relatives into assisting with the rearing of ...

New blueprint for more stable quantum computers

Researchers at the Paul Scherrer Institute (PSI) have put forward a detailed plan of how faster and better defined quantum bits—qubits—can be created. The central elements are magnetic atoms from the class of so-called ...

Logic

In philosophy, Logic (from the Greek λογική logikē) is the formal systematic study of the principles of valid inference and correct reasoning. Logic is used in most intellectual activities, but is studied primarily in the disciplines of philosophy, mathematics, semantics, and computer science. It examines general forms which arguments may take, which forms are valid, and which are fallacies. In philosophy, the study of logic is applied in most major areas: ontology, epistemology, ethics, metaphysics. In mathematics, it is the study of valid inferences within some formal language. Logic is also studied in argumentation theory.

Logic was studied in several ancient civilizations, including the Indian subcontinent, China and Greece. Logic was established as a discipline by Aristotle, who gave it a fundamental place in philosophy. The study of logic was part of the classical trivium, which also included grammar and rhetoric.

Logic is often divided into two parts, inductive reasoning and deductive reasoning.
