Critical thinking is the process of analyzing available facts, evidence, observations, and arguments to make sound conclusions or informed choices. It involves recognizing underlying assumptions, providing justifications for ideas and actions, evaluating these justifications through comparisons with varying perspectives, and assessing their rationality and potential consequences.

This principle, foundational for all mathematics, was first elaborated for geometry, and was systematized by Euclid around 300 BC in his book Elements. [ 21 ] [ 22 ] The resulting Euclidean geometry is the study of shapes and their arrangements constructed from lines, planes and circles in the Euclidean plane ( plane geometry ) and the three ...
George Finlay Simmons (March 3, 1925 [1] – August 6, 2019) [2] [3] was an American mathematician who worked in topology and classical analysis. He is known as the author of widely used textbooks on university mathematics.
One of Fuller's clearest expositions on "the geometry of thinking" occurs in the two-part essay "Omnidirectional Halo" which appears in his book No More Secondhand God. [ 2 ] Amy Edmondson describes synergetics "in the broadest terms, as the study of spatial complexity, and as such is an inherently comprehensive discipline."
Removing five axioms mentioning "plane" in an essential way, namely I.4–8, and modifying III.4 and IV.1 to omit mention of planes, yields an axiomatization of Euclidean plane geometry. Hilbert's axioms, unlike Tarski's axioms, do not constitute a first-order theory because the axioms V.1–2 cannot be expressed in first-order logic.
[1] [2] The program was led by Howard F. Fehr, a professor at Columbia University Teachers College. The program's signature goal was to create a unified treatment of mathematics and eliminate the traditional separate per-year studies of algebra, geometry, trigonometry, and so forth, that was typical of American secondary schools.

A student at Level 0 or 1 will not have the same understanding of this term. The student does not understand the teacher, and the teacher does not understand how the student is reasoning, frequently concluding that the student's answers are simply "wrong". The van Hieles believed this property was one of the main reasons for failure in geometry.
The Mathematical Association of America said about the book, "this book is a masterpiece — a delightful classic that should never go out of print". [4] Physics Today called it "a readable exposition of modern geometry and its relation to other branches of mathematics". [5] The Scientific Monthly said about it "has been a classic for twenty ...
