I generalized from those patterns, tried some more variations, generalized a bit further, then realized I had a method that seemed always to work.

BaalChatzaf 41 Report post Posted August 16, 2017 14 hours ago, Roger Bissell said: This is a false alternative. Zero is not absolute nothingness. But that doesn't mean it is something. It is the absence of something. Not the absence of anything whatsoever (that would be absolute nothingness), but the absence of something in particular. The phrase "zero apples" does not mean that there is some number of apples, and that number is zero. It means that there are not any apples, that any attempt to count the apples does not produce any results, and by convention, we say that we have "counted zero apples," when in fact we have not counted any apples. All of the so-called "algebraic properties" of zero are actually just the results of attempting to perform calculations in the absence of any quantity that one would normally be able to perform such calculations. Some say this is "a difference without a difference." By the same token, quantum mechanical equations produce the same results regardless of whether one adopts the Copenhagen interpretation or a more realistic interpretation. And perhaps there are not now any reasons for preferring one interpretation of the metaphysics of quantum mechanics or the metaphysics of zero over another. But I'm confident that there are reasons for preferring a realistic interpretation over one that reifies non-existence, even the relative or particular non-existence captured in how we use the concept of "zero" in mathematics. Even now, we have recently seen some Danish students who have found a method of measuring the position and momentum of subatomic particles, and who have thus proved that Heisenberg's Uncertainty Principle is ONLY the claim of a methodological limitation on simultaneous measurement of position and momentum of particles, and not a metaphysical law that such particles do not simultaneously possess position and measurement. For decades, the anti-Identity modern philosophers were pushing the former interpretation. But Aristotle has had the last laugh. And I'm chuckling along with him. https://www.sciencedaily.com/releases/2017/07/170712145654.htm What is being the identity element of the additive semi-group of counting numbers the nothingness of?

syrakusos 1 Report post Posted December 11, 2017 How the Martians Discovered Algebra: Explorations in Induction and the Philosophy of Mathematics by Roger E. Bissell delivers an algorithm for generating Pythagorean Triples. Central to the thesis of the work, Bissell explains how he discovered this by means of induction, not deduction. From there, Bissell takes the reader into number theory in order to validate his new explanation of the proper understanding of multiplication, and to challenge widespread assumptions about the empty set and infinity. The relationships between music and mathematics go back to Pythagoras. So, this set of essays by musician Roger Bissell enjoys a solid foundation. Bissell also dabbles at mathematics and has several philosophical explorations to his credit, published in The Reason Papers and the Journal of Ayn Rand Studies. Objectivism is an integration of rationalism and empiricism. Objectivism rejects the false dichotomies of Descartes, Hume, James, and the myriad other philosophers before and after. Consequently, Bissell and other Objectivists provide logically consistent, reality-based and practicable methods for understanding the universe including our inner selves. Objectivism is what the scientific method was intended to be: a guide to living. That said, this book failed to convince me on several points with which I was pre-disposed to agree. And I concede that the ultimate failure may be mine, not the author’s. Bissell begins with some techniques in speed math. These discoveries from his senior year in high school demonstrate his inductive method. They also provide an introduction to his algorithm for discovering Pythagorean Triples. That alone is worth the price of the book. It is easy enough to explain, though hard to show with the typesetting available here. Basically, you want three integers such that a^2 + b^2 = c^2. Easily, there must be some number, x to begin with. The other number must be some number added to x that can be expressed as x+a, and the result of adding their squares must be some (x+b)^2. It all follows from there. But I had a hard time following it. I tend to read at bedtime. So, I filled my notebook with pages with arithmetic when I was tired. I told Roger that his algorithms did not work. He asked me to send him PDF scans. I did. He corrected my homework. So, I agree that the Bissell Algorithm will, indeed, generate Pythagorean Triples. The central essay, “How the Martians Discovered Algebra” (Chapter 4) is a parable to demonstrate induction in mathematics as the doorway that opened to the world of algebra. Bissell's original algorithm for generating Pythagorean Triples is worth the price of the book. If you have any interest in epistemology, mathematics, or the problem of induction, then Roger Bissell's book delivers more for the money.Full review here:https://necessaryfacts.blogspot.com/2017/12/how-martians-discovered-algebra.html Share this post Link to post Share on other sites

When I was 14 years old I thought this up all by myself. It turns out that hundreds of mathematicians got to it hundreds of years before I did. Every mathematician or wanna-be mathematician goes through a Pythagorean phase. Every metric geometrical space which is smooth enough to be differentiable with continuous first derivatives is locally Euclidean. If you take a very small patch of the space, very very small it is nearly flat and Euclidean. So the geometry of planes is a kind of limiting case for all differential manifolds. The space may be bumpy or curved globally (like the surface of a sphere) but locally it desparately wants to be Euclidean. A Euclidean space is one where you can have arbitrarily large right triangles that obey Pythagoras' Theorem. Share this post Link to post Share on other sites

As the narrator said at the beginning, we have Pythagorean Triples on clay tablets. The Cartesian coordinate system was a logical leap from the meridians and longitudes used 2000 years earlier; it also can be laid to the checkerboard which is descended from the Roman abacus. We use, adapt, extend, invent... Some of us do, at any rate. (And, yes, a nice nod to you for having found that Pythagorean Formula on your own.) But you are stealing a concept here. Mathematics depends on deduction, of course. It also depends on natural language. But it is not solely any one mode to the exclusion of all others. And no one said it was. That is a straw man of your own construction. As for the number of great mathematicians who are Objectivists, the number may be zero, the same as the number who are Platonists, Humeans, or followers of DeLuze or Rorty. However, if you are counting great minds in order to decide what you should believe, then you should be a communist. As I understand it, of all the mathematicians of the 20th century and of all of the philosophies known at least to 1989, the only consistent correspondence was the great mathematicians of the USSR. On the other hand, it might also be said, more truthfully, that every mathematician, whatever their stature in your mind, is an Objectivist to the extent that they recognize reality, conform to reason, and place no one else's judgment above their own... which suggests that all of those communist mathematicians were lying to save their skins -- also a logical course of action based on the facts of reality.

The reply is: how in the world ELSE do you think you can "get" them - or this marvelous display of all the Pythagorean triples? You cannot get abstract conceptual products without lower-level concepts based on sense perception - and you cannot get deductive conclusions without inductively gained information and conclusions on which all deduction is necessarily based. As I stated in my book, "Not that deduction is insignificant. It is the engine of proof, after all.

It was induction based on observation of numerical relations aligned in columns that made certain additional relationships observable. Not all that different from being a medical examiner or forensic scientist: you lay out the data in a helpful way and look for connections. But in induction, you look for *repeated* connections that have a necessary foundation, and then you figure out what that foundation is and express it as a generalization. And then you try to link it to your other knowledge and give a deductive validation of it. But I didn't think the inductive part of my work was all that clever. It was just a lot of hard work and attention to detail and to patterns in that detail. It was when I hit upon the idea of validating my method by solving the Pythagorean equation that I thought I was particularly clever. It was mind-crunchingly difficult to actually solve it, but I figured what the hell, put on your big boy pants and do it. And the payoff was that I validated my method. If the Pythagorean equation was true, then so was my method. Q.E.D. And actually, I didn't get to Pythagoras's equation by induction. I got my Pythagorean triple method by induction and I validated it by solving Pythagoras's equation by completing the square. I took Pythagoras's equation as a given and deduced what it would mean about the relationships between all the terms in the equation - which exactly matched what I had developed inductively from the columns of numbers that in no way depended on the Pythagorean equation (except that I worked with squares and the like, instead of cubes or square roots etc.).
