Logic is a branch of philosophy that deals with reasoning. Logic is used in mathematics, computing, philosophy, culture, and more. This section covers all formal and informal logic and all sub-sets of logic.

## The Branches of Philosophy Overview

The major branches of philosophy can be denoted as: metaphysics (what is), epistemology (what we can know), logic and reason, ethics and morality, and aesthetics (beauty and art).

## If a Tree Falls in a Forest and No One Can Hear it, it Makes a SoundFact

According to physics, if a tree falls and no one is around to hear it, it still makes a sound. Sound is a mechanical wave of pressure and displacement through a medium such as air or water. We don’t have to perceive a sound to know the laws of physics are in play.

## A System is a Set of PropertiesFact

A system is any “bound”, finite, set of physical and/or conceptual properties (elements) such as physical objects, rules, or space time coordinates.

## A Small Part of a Curved Surface Will Look “Flat”Fact

If you look at a curved surface from close up it will look “flat”, if you change your perspective and “zoom out” it will look “round”.

## Infinity is a NumberMyth

Infinity (∞) isn’t a number, it’s a concept. It describes something that can’t be expressed by a “finite” natural or real number.

## There are Different Types of InfinityFact

There are different types of infinity (∞) which differ by size, countability, “flavor” and more. Most types have practical real world applications.

## The Earth Isn’t FlatFact

The Earth is not flat; the Earth is an oblate spheroid (a bumpy sphere with a fat equator and skinny poles). There are many ways to prove the earth’s geometry.

## People Can be Truly UnbiasedMyth

People can’t be truly unbiased; we are hardwired with bias and create bias constantly as part of the natural neurological process of learning.

## Correlation Does Not Imply CausationFact

Correlation does not imply causation, but it can indicate it. The more correlating factors between events, the more likely there is a causal relationship.

## Past Outcomes of Random Events Affect Future OutcomesMyth

Past results of random independent events, like a coin flip, don’t affect future results. The mistaken belief that past results affect future results is known as “the Gambler’s Fallacy” (AKA the Fallacy of the Maturity of Chances, or the Monte Carlo Fallacy).
