Discussion Overview

The discussion revolves around recommendations for linear algebra textbooks, focusing on the preferences and experiences of participants with various texts. The scope includes conceptual understanding, readability, and the suitability of different books for learners at various levels.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Technical explanation

Main Points Raised

  • One participant expresses dissatisfaction with David Lay's Linear Algebra and its Applications, citing issues with notation changes, lack of significant examples, and a perceived lack of conceptual cohesion.
  • Another participant recommends Axler's Linear Algebra Done Right for its motivational approach and clean presentation, but notes that it may be too abstract for beginners.
  • A third participant agrees with the recommendation of Axler but suggests Anton's Elementary Linear Algebra as a gentler alternative for those new to the subject.
  • A participant indicates a preference for intuitive examples and a theoretical approach, expressing difficulty in relating theory to practical applications.

Areas of Agreement / Disagreement

Participants generally agree that Lay's book has shortcomings, but there is no consensus on the best alternative, with differing opinions on the suitability of Axler and Anton's books for beginners.

Contextual Notes

Some participants mention the need for more intuitive examples and the challenge of translating theory into practical understanding, indicating a potential gap in the resources available for learners with different preferences.

Who May Find This Useful

I've seen loads of "what is the best Linear Algebra" threads but none quite match what I'm looking for. I'm currently using David Lay's Linear Algebra and its Applications, and I find the book readable, but strange.

He changes notations quite often and sometimes I have to try to figure out what he's talking about because his notations are different yet again. Also, his examples are not really illustrative of anything significant, are but simple calculations and step-by-step guides to how to solve problems.

I also find that it is not conceptually cohesive. I'm taking a summer course in Linear Algebra right now and it introduced a lot of terminology: "This is called x" but doesn't make it relevant what x actually signifies. As I progressed in math I found that a lot of the "jargon" are actually very meaningful, and I'm not getting that here, and the pace at which we're going only ensures that one day my ADHD brain will bet bowled over by all the terms. Maybe I'm missing the point, but I don't think he ties together concepts well.

I read a lot of good reviews on Shilov's book but also that it's not good for first-timers and wouldn't really be compatible with the course I'm taking- my professor pretty much lectures straight out of the book. Is there a good textbook that is more conceptual, but still accessible?

Hey Rubicon, welcome to the physics forums!
I have read a bit of Lay's book, and am not a big fan of it. My favorite book on linear algebra is Axler's Linear Algebra Done Right. It provides plenty of motivation for the subject, and uses a clean, operator-theory approach that doesn't needlessly bring up matrices and determinants when they are not needed.

However, it is a pretty abstract treatment, in the classic theorem, proof, theorem, proof,... style. Are you looking for something with more physical or intuitive examples?
 
I second Axler, but as already noted he is not good for a first contact with LA. You could try Anton's elementary linear algebra for a gentler approach.
 
Thanks for the responses. Generally I like more intuitive examples. For some reason I have a hard time translating between theory and reality and physical examples always make me think of more variables than are relevant in the problem. I'm not very good at applied math and generally appreciate a more theoretical approach. I always "see" better when the examples are just points and lines, and when I think about things, even in other subjects such as history, I tend to see forces and light blots and colors.
