The fundamental dream of algebra | Abstract Algebra Math Foundations 216 | NJ Wildberger
 
27:19
This video reveals the unfortunate truth about the "Fundamental Theorem of Algebra": namely that it is not actually correct. This is meant to be a core result in undergrad mathematics, but curiously undergrads don't see much in the way of proof. Why? Because none of the many current arguments are actually convincing once one stops and looks carefully at them. Modern mathematics students: prepare for some disruption to your thinking! Modern mathematicians: is it not time to admit the harsh reality? This entire topic is intimately connected with what I consider the fundamental problem in mathematics, which I discuss in the Famous Math Problems 19 lectures. And so we need some seriously new thinking. We need to peel back the layers of conformity, imprecise thinking and wishful dreaming that characterize so much of modern pure mathematics.

What is the Fundamental theorem of Algebra, really? | Abstract Algebra Math Foundations 217
 
28:27
Here we give restatements of the Fundamental theorems of Algebra (I) and (II) that we critiqued in our last video, so that they are now at least meaningful and correct statements, at least to the best of our knowledge. The key is to abstain from any prior assumptions about our understanding of continuity and "real " or "complex" numbers, and state everything in terms of rational numbers. For this we briefly first review some rational complex arithmetic, crucially the concept of quadrance of a complex number which ought to be a core definition in undergraduate courses. These restatements were first proposed some years ago in my AlgTop series of videos. It should be emphasized that we do NOT currently have proofs for these "theorems", so there is a huge opportunity here for people to make a significant contribution to mathematics. But new and deeper understanding is required, at least I believe so, and hopefully we can aspire to computationally oriented proofs, that actually tell us how to go about finding approximate zeroes to a prescribed level of accuracy. Working this out satisfactorily will be as significant an accomplishment as any 20th century mathematical achievement.

The Algebra of Boole is not Boolean algebra! (III) | Math Foundations 257 | N J Wildberger
 
27:24
We continue discussing George Boole's original algebra which can be framed as arithmetic over the bifield B_2={0,1} and vector spaces/algebra over it. We have seen how to reformulate Aristotle's syllogistic construction in terms of Boole's algebra, and use simple algebra to prove his syllogisms. The situation is somewhat more complicated for third figure syllogisms, such as Darapti, for which "existential import" is required. This is dealing with statements about situations for which there are no instances---i.e. talking about mermaids, leprechauns, unicorms, or infinite sets :). Then we finish the lecture by introducing the subtle, but important, distinction between the Algebra of Boole which we have been studying, and so-called Boolean algebra, which is currently used in circuit analysis, and connects more directly to set theory.

An introduction to abstract algebra | Abstract Algebra Math Foundations 213 | NJ Wildberger
 
25:38
How do we set up abstract algebra? In other words, how do we define basic algebraic objects such as groups, rings, fields, vector spaces, algebras, lattices, modules, Lie algebras, hypergroups etc etc?? This is a hugely important question, and not an easy one to answer. In this video we start by giving a bird's eye view of some basic examples, namely the first four kinds of objects on this list. We will not attempt complete definitions, but just rather provide intuitive example based descriptions, using the standard thinking current in mathematics these days. In some videos, we will be looking to reorganize our understanding of all of these topics by being much more precise and careful, and utilizing our knowledge of data structures.

The Algebra of Boole is not Boolean Algebra! (I) \ Math Foundations 255 | N J Wildberger
 
37:43
We begin to introduce the Algebra of Boole, starting with the bifield of two elements, namely {0,1}, and using that to build the algebra of n-tuples, which is a linear space over the bifield with an additional multiplicative structure. This important abstract development played a key role in the application of logic to circuit and logic gate analysis. Surprisingly it is not quite the same as Boolean algebra, which is closer to the arithmetic of sets. We will move towards understanding the critical difference between these two mathematical approaches to logic. However in both cases, the situation is that mathematics was introduced to make logic more precise and rigorous---- not the other way around! This understanding has major ramifications for an appreciation of why 20th century mathematics got things so fundamentally wrong!

Introduction to Algebra | Arithmetic and Geometry Math Foundations 46 | N J Wildberger
 
09:46
There are three main branches of mathematics: arithmetic, geometry and algebra. This is the correct order, both in terms of importance and of historical development. Here we introduce our program for setting out foundations of algebra. This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics.

The Algebra of Boole is not Boolean Algebra! (II) | Math Foundations 256 | N J Wildberger
 
30:04
We investigate further the Algebra of Boole, consisting of vectors of 0 and 1 of a given size, with operations pointwise mod 2. The idempotent law x^2=x of Boole is distinguished. To illustrate the geometry, we look at a 5 dimensional example and the span of three vectors, along with the algebra generated by them, giving both a 3 dimensional cube and a 4 dimensional hypercube. Then we introduce the square of opposition going back to medieval philosophers, now in algebraic form by re-interpreting Aristotle's propositions using Boole's algebraic reformulation. Then armed with this mathematical framework, we begin the fun task of proving Aristotle's syllogistic rules using just mathematics! Including Barbara, Celarent, Cesare and others.

Linear spaces and spans I | Abstract Algebra Math Foundations 219 | NJ Wildberger
 
24:14
The simplest and most common examples of abstract algebraic objects are probably linear spaces. They occur in many areas of mathematics, and are pillars of linear algebra, where they are often called vector spaces. Our approach will be to generalize simple aspects of Nat, Int and Rat from a data structure orientation, prominently using multisets, or msets. In this lecture we start with the idea of generalizing Nat with addition, to form spans of msets.

The first of a series that will discuss foundations of mathematics. Contains a general introduction to the series, and then the beginnings of arithmetic with natural numbers. This series will methodically develop a lot of basic mathematics, starting with arithmetic, then geometry, then algebra, then analysis (calculus) and will also treat so called set theory. It will have a lot of critical things to say once we get around to facing squarely up to the many logical weaknesses of modern pure mathematics. The series is meant to be viewed sequentially. We spend a lot more time and effort than usual on fundamental issues with number systems. If you are a more advanced student, or a fellow mathematician, then the first few dozen videos might be a bit slow. But they are none-the-less important!

Why roots of unity need to be rethought | Abstract Algebra Math Foundations 218 | NJ Wildberger
 
29:26
Roots of unity as regularly spaced points on the unit circle in the complex plane are common-place objects in algebra, but they implicitly rely on the Fundamental theorem of algebra for their existence. But their existence, in fact their definition, is fraught with logical difficulty, at least when we view them in the complex plane. In this video we summarize some basic algebraic and geometrical properties of complex numbers, centered on the rational parametrization of the unit circle. There is a huge difference between specifying a unit quadrance complex number by an expression like 3/5+4i/5 and cos 4+i sin 4. Once we understand that, we can start to appreciate the logical difficulty in supposing that something like the seventh roots of unity really do exist, perfectly spaced around a regular septagon.

Boolean algebra and set theory | Math Foundations 259 | N J Wildberger
 
28:07
After George Boole's introduction of an algebraic approach to logic, the subject morphed towards a more set theoretic formulation, with so called Boolean algebra initiated by John Venn and Charles Peirce. Venn diagrams (originally going back to Euler), give us a visual way of representing relations between subsets of a universal set. The operations of meet and join, or intersection and union, together with taking complements become replacements for the product and sum of the Algebra of Boole. In this set theoretic context, de Morgan's laws clarify how to compute complements of unions and intersections, and the two distributive laws involve 3 sets, and either a union of an intersection, or the intersection of a union. We illustrate how to verify these laws from, first of all a truth table perspective, and then with computations using the Algebra of Boole. There is a heretical message here: professors teaching circuit analysis to engineers might want to start thinking about revamping their subject, and replacing Boolean algebra with the original, more powerful and simpler Algebra of Boole!

Logical challenges with abstract algebra II | Abstract Algebra Math Foundations 215 | NJ Wildberger
 
19:49
There is a very big jump in going from finite algebraic objects to "infinite algebraic objects". For example, there is a huge difference, if one is interested in very precise definitions, between the concept of a finite group and the concept of an "infinite group". We illustrate this important distinction in this video by looking at a rich and interesting example: SL(2) with just 0,1 entries mod 2, which is a lovely and special finite group, and SL(2) with arbitrary integer entries, which is also an interesting and important mathematical object, but which ought to be defined and treated differently. Of course one of the advantages in the modern sloppy approach to the definition of a "set" is that it does not distinguish at all between a collection that can be explicitly listed and one that cannot be. So this meaningful distinction can be left under the carpet.

A broad canvas: algebra with maxels from integers | Data Structures Math Foundations 209
 
21:20
Matrix theory is just a shadow of the more fundamental and far-reaching maxel theory. In our last video we introduced maxels from integers, which gives us a broad canvas to restructure matrix theory, extending to integer indices. In this video we begin to discuss the ramifications of this larger two-dimensional view of linear algebra. We review some constructs from earlier videos, and extend them to this more general set up, such as the partial identity maxels e_J corresponding to a set J of integers that allow us to identify matrix subalgebras inside our maxels. A lovely feature of this view is that a fundamental shift invariance comes into focus, which is not available in the more classical matrix view. The entire integer screen supporting maxel theory has a symmetry which allows us to shift up or down along the main diagonal.

One important use of letters in algebra is to describe patterns in a quantitative and general way. We look at the `sequences' of square numbers and triangular numbers, and derive formulas for the nth terms. A table of differences shed light on these and other number patterns. This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics. Screenshot PDFs for my videos are available at the website http://wildegg.com. These give you a concise overview of the contents of each lecture. Great for review, study and summary.

A brief history of logic: from Leibniz to Boole | Math Foundations 254 | N J Wildberger
 
28:07
In the modern European era, medieval logic is replaced with new directions, motivated by an increased interest in systematizing reasoning. A prominent thinker in this direction is G. Leibniz, who applied his genius to, among many other things, the idea of a computing device and language that might allow systematic, even mechanical reasoning. In the 18th century, Euler, Lambert and Ploucquet introduced diagrams for representing logical relations. And then in the 19th century we move to more dramatic developments, largely due to the work of De Morgan and George Boole. We include some original work by Boole himself to get a sense of his thinking. This is when mathematics first intrudes on classical logic, presenting an algebraic approach to Aristotle's syllogisms, while both expanding the subject and restricting its interpretation to binary possibilities.

Implication and 16 logical operations | Math Foundations 258 | N J Wildberger
 
36:54
Given two binary inputs p and q, there are four possible assignments of 0's and1's to them, and correspondingly 16 different possible connectives or operations on these four assignments. The systematic study of these 16 connectives forms the foundation for both Boole's algebra, Boolean algebra, and modern circuit analysis. We want to position these subjects so that Boole's algebra is primary. We introduce AND, OR, XOR gate terminology, as well as the negations NOT, NAND, NOR, XNOR and also the implication operations IMP and NIMP. We illustrate the situation with a study of Modus Ponens both through truth tables and a more algebraic analysis based on Boole's algebra. This will give us a powerful new insight that allows us to apply very elementary polynomial algebra to solving complex problems in electrical engineering.

Baby Algebra | Arithmetic and Geometry Math Foundations 47 | N J Wildberger

Algebra starts with the natural and simple problem of trying to solve an equation containing an unknown number, or `variable'. Here we start with simple examples familiar to public school students. This video belongs to Wildberger's MathFoundations series, which sets out a coherent and logical framework for modern mathematics. The idea is to transform an equation with a variable into a simpler but equivalent equation, which can be more easily solved. We review examples of such manipulations--that go back to Hindu and Arab mathematicians. My research papers can be found at my Research Gate page, at https://www.researchgate.net/profile/Norman_Wildberger. I also have a blog at http://njwildberger.com/, where I will discuss lots of foundational issues, along with other things, and you can check out my webpages at http://web.maths.unsw.edu.au/~norman/.

The algebra of natural number multisets | Data structures in Mathematics Math Foundation 157
 
23:05
We introduce some deceptively simple but important notation to deal with multisets/msets from n, for some natural number n. In particular we augment addition of msets with multiples of an mset, and use that to give a list-theoretic description of the multiplicity of various elements that appear in a given mset. In particular this suggests the possibility of extending multiplicities to have negative, or even rational number values. Both of these ideas will have major consequences as we use data structures to help us structure parts of modern algebra.
