• 23:2123:21, 20 January 2024 diff hist +435‎ N Circle ‎ Created page with "A '''circle''' is a closed curve on a plane, which is equidistant from a point. A circle should be distinguished from the closely related concept of a loop, or an <math>S^1</math>. To emphasize the distinction from loops, a circle is sometimes called a '''rigid circle'''. Circles are one of the central concepts objects of classical geometry. == Examples == === Circles === === Non-circles ===" Tag: Visual edit

The numerical value of π depends on context: which circle is under consideration, and how precise are one's measurements? == The traditional concept == Standard mathematics says that π is the ratio between the circumference and the diameter of a ''perfect'' circle. Consequently, π is an irrational number." Tag: Visual edit

Loosely speaking, standard mathematics defines the square root of, say, 2, to be the positive number <math>r</math> such that <math>r^2 = 2 </math>. It is well known that no rational number satisfies that equation. Solutions to that equation can at..." Tag: Visual edit

This will be done by painstakingly going through each math concept, and thinking about the concrete, perceptual data to which it ultimately refers. If a math concept is ''not'' reducible to perceptual concretes, it is invalid; it is a floating abstraction. Objective Mathematics rejects Platonism: math concepts are not Platonic f..."

Penguin, 1990.</ref> Any page on the Objective Mathematics wiki is a concept. == Notion == A '''notion''' is a compound concept. A notion is like a concept, in the sense that it subsumes and includes an unlimited number of concretes. A notion is unlike a concept, in the sense that it might be made of other concepts. Examples: * 3 is a concept, but 16654 is a notio..." Tag: Visual edit

In short, this is because an infinite set does not refer to anything that can be perceived. The concept in Objective Mathematics which is closest to that of an infinite set is that of a concept. === But what about extended objects? === There are an unlimited number of points on an extended object. It..." Tag: Visual edit
