What is a logical fallacy?
A "fallacy" is a mistake, and a "logical" fallacy is a mistake in reasoning. There are, of course, other types of mistake than mistakes in reasoning. For instance, factual mistakes are sometimes referred to as "fallacies". However, The Fallacy Files is specifically concerned with logical errors, not factual ones. A logical error is a mistake in an argument, that is, a mistake in an instance of reasoning formulated in language. As the term is used in logic, an "argument" is a group of statements one of which is called "the conclusion" and the rest are called "premisses"―by the way, I spell "premiss" with two esses instead of one, for reasons explained in the Glossary; in other words, this is not a spelling mistake.

So, there you are staring at that black sheet of paper again. Or perhaps it's a black Word document on your computer screen. Whichever it may be, it's obvious you're about to take notes for that big essay assignment or group project, and you're not too excited about getting started! That's where a different kind of note taking comes in to play, one that is actually fun to do and will also help you to understand your notes better. It's a technique called mind mapping, and is based around a strong visual method of taking notes. Whether your using colorful markers and paper or using state-of-the-art computer software, you'll find using mind maps are a much more interesting way to take notes than you ever have in the past!
BOS academic : Folding angles of 30 and 60 degrees
Folding angles of 30 and 60 degrees by Ian Harrison For those of us who fold paper regularly, creating angles of 90o and 45o is almost second nature. We create a right angle by folding an edge, or a crease, back on itself, and we can bisect a right angle (or any other angle) by bringing the folds/edges that form the two arms of the angle together, and creasing between them. The mathematics of folding angles of 60o or 30o is only slightly more difficult to understand. (The other angles that paper-folders - especially modular paper-folders - often need to construct are the angles of 108o and 72o, useful in making polyhedra with pentagonal faces, and other related forms.)
Model Theory
1. Basic notions of model theory Sometimes we write or speak a sentence S that expresses nothing either true or false, because some crucial information is missing about what the words mean.
Twelve Virtues of Rationality by Eliezer Yudkowsky
by Eliezer Yudkowsky The first virtue is curiosity. A burning itch to know is higher than a solemn vow to pursue truth. To feel the burning itch of curiosity requires both that you be ignorant, and that you desire to relinquish your ignorance. If in your heart you believe you already know, or if in your heart you do not wish to know, then your questioning will be purposeless and your skills without direction. Curiosity seeks to annihilate itself; there is no curiosity that does not want an answer.
ThinkSkill
Life is confusing. What does it all mean? So begins philosophy. When you think philosophically, you question your assumptions about yourself, other people, and the world, to clarify your perspective and deepen your understanding of what matters to you. You can pursue these questions as far as your curiosity desires, but when you think philosophically about your choices, you naturally have a practical end in view: you want to make the wisest choice you can.
How To Mind Map
A mind map is a type of (radial) diagram that contains words, ideas or tasks that are linked around a central idea or keyword. A mind map can be drawn by hand or by means of a computer, before a particular lesson, while attending the class or even after the lecture has finished. Popular Usage
Huzita-Justin Axioms
At the First International Meeting of Origami Science and Technology, Humiaki Huzita and Benedetto Scimemi presented a series of papers, in one of which they identified six distinctly different ways one could create a single crease by aligning one or more combinations of points and lines (i.e., existing creases) on a sheet of paper. Those six operations became known as the Huzita axioms. The Huzita axioms provided the first formal description of what types of geometric constructions were possible with origami: in a nutshell, quite a lot was possible!

The instructor strode into the classroom empty handed. He nodded to the class and checked his watch. Seven P.M. Every chair was occupied, fifty in all. Many students wore business suits, ties pulled loose.
