#### 26 August 2016

• (diff | hist) . . Geometry/Chapter 1‎; 21:42 . . (-79). .Sluffs(Section 1.3 - Undefined Terms: removed - (again, more later) - not needed)
• (diff | hist) . . Geometry/Chapter 1‎; 21:39 . . (-22). .Sluffs(Exercises: getting my premises and predicates mixed up - corrected)
• (diff | hist) . . Geometry/Chapter 1‎; 21:27 . . (+248). .Sluffs(Exercises: added that these logic questions are based on the major/minor premise form and that the subject of the premise must be part of the affirmative or negative answer - otherwise the exercises are difficult)

#### 24 August 2016

• (diff | hist) . . m Geometry/Chapter 1‎; 23:39 . . (-71). .Sluffs(Section 1.2 - Reasoning: removed link to Wikipedia article - not needed - the following material deals with the matter)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:36 . . (+5). .Sluffs(Section 1.1 - Introduction)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:35 . . (-61). .Sluffs(Section 1.1 - Introduction)
• (diff | hist) . . Geometry/Chapter 1‎; 23:34 . . (-208). .Sluffs(Section 1.1 - Introduction: removed sentenceː "Although this textbook is not a re-interpretation of ''The Elements'', it will include more than just facts about geometric objects..." - Reasonː not needed - the introduction is fine)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:18 . . (+1). .Sluffs(Section 1.1 - Introduction)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:17 . . (-1). .Sluffs(Section 1.1 - Introduction)
• (diff | hist) . . Geometry/Chapter 1‎; 21:51 . . (-68). .Sluffs(Section 1.1 - Introduction: removedː (or elementary) - not so much elementary because it involves abstract concepts such as ratio, equality, boundary - e.g. for equalityː if A is equal to C and B is equal to C than B is equal to A)
• (diff | hist) . . m Geometry/Chapter 1‎; 02:26 . . (-114). .Sluffs
• (diff | hist) . . Geometry/Chapter 1‎; 02:23 . . (-63). .Sluffs(Inductive Reasoning: removedː "Looking at the example above you may" - not needed - the previous editors shows clearly why squaring a half results in a quarter)
• (diff | hist) . . m Geometry/Chapter 1‎; 02:19 . . (-2). .Sluffs(Inductive Reasoning)
• (diff | hist) . . Geometry/Chapter 1‎; 02:18 . . (+23). .Sluffs(Inductive Reasoning: changedː "Based on observations, this appears to be true." to "Based on the result of squaring whole numbers this appears to be true." - it doesn't matter if its negative or positive - it is still a whole number)
• (diff | hist) . . Geometry/Chapter 1‎; 02:13 . . (-2). .Sluffs(Inductive Reasoning: "A beginning observer of American baseball may conclude" - changed "beginning" to "foreign" - that is nearer to no knowledge of the game)
• (diff | hist) . . Geometry/Chapter 1‎; 01:46 . . (+201). .Sluffs(Inductive Reasoning: this paragraph ends with Kuhn - but he is not mentioned so I added his name and the concepts of "paradigm" and "generalizations" - the importance of this is not lost on those who have read the "Almagest" by Ptolemy)
• (diff | hist) . . Geometry/Chapter 1‎; 01:22 . . (-68). .Sluffs(Section 1.1 - Introduction: typo and removed link to Nasa)
• (diff | hist) . . Geometry/Chapter 1‎; 00:27 . . (+27). .Sluffs(Section 1.3 - Undefined Terms: adding that Hume considered all knowledge "a posteriori" which I've just discovered gave Einstein the reason to abandon the axioms of Euclidean geometry to invent a curved time-space theory- oh well learn something new)
• (diff | hist) . . Geometry/Chapter 1‎; 00:21 . . (-69). .Sluffs(Section 1.3 - Undefined Terms: removed bold - not needed and looks better - bold is useful but the terms were "segment", "ray", and "angle" which I think most people would know)

#### 23 August 2016

• (diff | hist) . . Geometry/Chapter 1‎; 23:55 . . (+2). .Sluffs(Section 1.3 - Undefined Terms: changed word to "understanding" - I'm a bit puzzled why this whole section is called "Undefined Terms" - they are either a priori or a posteriori but all things are defined - it should be "Postulates or Common Notions")
• (diff | hist) . . Geometry/Chapter 1‎; 23:48 . . (+151). .Sluffs(Section 1.3 - Undefined Terms: adding Hume and his work On Human Nature - basically the questioning of axioms was a youthful Hume - the point he was illustrating was that the study of human nature may be approached from science)
• (diff | hist) . . Geometry/Chapter 1‎; 23:22 . . (+24). .Sluffs(Deductive Reasoning: adding "that are not parallel will intersect" to "it can be used to deduce that two different lines intersect in at most one point." - in the sense of extended without limit)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:15 . . (+6). .Sluffs(Section 1.2 - Reasoning: Chicago Manual of Styleː spell non-technical numerals below one-hundred)
• (diff | hist) . . Geometry/Chapter 1‎; 23:13 . . (-25). .Sluffs(Section 1.2 - Reasoning: removed Wikipedia link to Baseball article - keep focus on geometry)
• (diff | hist) . . Geometry/Chapter 1‎; 23:09 . . (-18). .Sluffs(Section 1.1 - Introduction: tightened sentence - no need for the demonstrative pronoun "that" - I'm not sure if it is "his method" - many of the proofs were common knowledge - I thought he was the first to order them)
• (diff | hist) . . m Geometry/Chapter 1‎; 23:01 . . (-2). .Sluffs(Section 1.1 - Introduction: no need for speech marks - no emphasis needed)
• (diff | hist) . . Geometry/Chapter 1‎; 22:59 . . (-2). .Sluffs(Section 1.1 - Introduction: rewrote "In the book, Euclid started with some basic concepts. He built upon those concepts..." - "In this book Euclid provides methods using just a compass, ruler and a protractor to prove geometrical statements.")
• (diff | hist) . . Geometry/Chapter 1‎; 22:38 . . (-4). .Sluffs(Section 1.1 - Introduction: removed speech marks from "proof" - not needed)
• (diff | hist) . . Geometry/Chapter 1‎; 22:37 . . (-29). .Sluffs(Section 1.1 - Introduction: removing Wikipedia links - same reason as before)
• (diff | hist) . . Geometry/Chapter 1‎; 22:28 . . (-25). .Sluffs(Section 1.1 - Introduction: Removed speech marks on the first word of a paragraph - not needed - also there is no need to link to the Wikipedia article - this book can go way beyond an article)
• (diff | hist) . . Geometry/Chapter 1‎; 22:22 . . (-2). .Sluffs(Section 1.1 - Introduction: removed brackets - not needed - the sentence is fine - shouldn't how Eratosthenes measured the Earth be included - wasn't it quite a distance between the well and the other point)
• (diff | hist) . . Geometry/Chapter 1‎; 22:12 . . (+5). .Sluffs(Section 1.4 - Axioms/Postulates: rewrite - the paragraph "Undefined Terms" is very abstract - wouldn't it be better to go straight to the Axioms)
• (diff | hist) . . Geometry/Chapter 2[review]; 00:58 . . (-1). .2602:30a:2cbe:8760:9dc6:f173:46cd:e96f (discuss)(Two-Column Proofs)
