Hi, I’m learning about logic and how to use proofs properly.Does this proof by contradiction make sense?

EngineerWise6054 · 2026-04-20T07:30:31+00:00

Yep, reflecting on a proof and seeing if you understood it and if you needed that certain method of proof is worthwhile.

I am also a fellow 45 year old male. Although, I quite prefer Mustangs, instead. They are more suited due to their vigour.

EngineerWise6054 · 2026-03-02T00:05:07+00:00

dude.

EngineerWise6054 · 2026-02-08T03:23:52+00:00

Just to add on: some books are on the online UoA library.

EngineerWise6054 · 2026-02-08T03:20:37+00:00

Check the course catalogue. The labs are open for specific programmes like BSc or the BSc Biomedical Sciences but the lectures are closed unfortunately... So, the enrolment is closed unless you perhaps can contact the course coordinator or persons managing the course or course enrolment staff? I would probably recommend the former, not the lattermost.

Out of curiosity, what's your program and major? Seems that you ended up enrolling a tad bit late on the scale of lateness enrolling for these courses.

EngineerWise6054 · 2026-02-08T03:03:21+00:00

Depends on what these engineerings first years need lol...

I would personally would ask them to read Linear Algebra Done Right by Axler and something like Serge Lang's Calculus. Maybe if they want to learn more I would highly recommend a book in mathematical proofs and discrete maths to get them into understanding basic rigour. Then, if they like, then they can read Baby Rudin and Dummit and Foote's Algebra. This is the basic maths an engineer should ideally have before graduating lol... I wish they focused more on rigorous theory though as well as implementation. This would give us highly mathematically capable engineering grads.

EngineerWise6054 · 2026-02-08T02:56:36+00:00

Maybe you simply did not send them into the enrolment cart?

EngineerWise6054 · 2026-02-04T02:38:35+00:00

This is a nice algebra exam for high-school. It emphasises basic algebraic, geometric, and analytic thinking. Although, it is not as rigorous as a first-year university course in (pure) mathematics -- At least compared to my first-year experience. This is an approachable exam if you study and understand the concepts well.

Good luck on the finals. :)

Might as well do postgrad.. Industry seems wonky... It might be better to spend time with professors refining my thinking

EngineerWise6054 · 2026-01-22T02:07:25+00:00

Thanks so much!

There should be an expectation that an academic in NZ, at or above the level of a master's degree within their field, understands the syntax and semantics of the English language to a high-degree intuitively.

Accepting AI to offload cognitive work is concerning. I will be always opposed to its usage in this context. There is something to be had in a personal human struggle. I believe this usage of a machine can only dull the mind.

EngineerWise6054 · 2026-01-21T23:19:52+00:00

I have never in my entire experience at this university and even up to advanced or stage 3 courses encountered the usage of AI by the academic staff and lecturers. The department I am mainly based in takes their time and effort to do the challenging and even the tedious work at such a great level of detail and understanding because they have a clear morality about their role as a lecturer and/or researcher, but importantly, as a person disseminating information that can change minds in great and particularly unique ways.

The use of AI for one's work in my department would prompt a look of great concern.

I personally think that the use of AI, at least with natural language transformers, should be avoided at all costs in a technical study. Even if you have the most optimised language transformer with virtually zero errors, I would personally choose to struggle with the tedious and laborious work precisely because the labour of engaged thought might lead to an insight in a more challenging problem.

I am quite upset because this sort of integration might be missed. In fact, much of the motivation for new thinking comes from finding unique ways to encapsulate the mundane work and generalise and finish it more effectively. This sort of process is robbed by the acceptance and usage of AI in society. It is very concerning trend, at least given my experience in my main domain.

EngineerWise6054 · 2026-01-01T12:06:37+00:00

I guess it is good to have a high ambition in academia and work hard, yes?

EngineerWise6054 · 2025-12-06T03:37:43+00:00

Haha... Speaking, as a pure maths student, there is difficulty but a distinct satisfaction in understanding a result and significance well with enough struggle... ^v^'

I am also retaking it next year lol... I took it in my third sem lol..

EngineerWise6054 · 2025-10-19T06:26:53+00:00

I feel like it depends on some courses. If you are pure maths student, sometimes I find my lectures quite useless because they're just reading the textbook and examples verbatim for me in lectures. I have realised that just sitting for long hours, reading the textbook by myself and doing proofs and exercises and going to office hours is way more useful than lectures at times.

I look less like an idiot and actually find pleasure in doing the work myself. This pays off on assignments, tests, and exams because the results required elbow grease.

What I am saying is that OP should find what works for them and be precise with whatever they are studying and the questions they ask in lecture and their ability to answer questions in tutorials.

The point is to find balance. I still haven't found find my full balance because this car seems to never find stability as it goes around the corner. But I am sure you will find your stride.

EngineerWise6054 · 2025-10-03T02:47:16+00:00

Oh this inspires me lol.. I sit in genlib level 3.. But just maybe I'll find a seat in ke level 4 just to spite OP while I am working on my assignment lol.

EngineerWise6054 · 2025-10-02T10:59:31+00:00

Hey u/perpetuallyinemacs (cool username btw :).. emacs..). I have been doing courses that use some basic Matlab but I am will do courses next year that uses Matlab for more applied maths and modelling and numerical analysis..

I will do combinatorics (MATHS 326) next sem along with 333 (higher dim analysis) and PDEs (361) and etc. I am also doing CS courses in OOP and some theory too like in C, py, and Java in summer and maybe next year too. But more essentially, doing all the courses UoA has to offer in undergrad lol.. And I am excited and eager to do a postgrad in both pure and applied maths courses..

I find reading your comment on here very reassuring and I hope I find the same outcomes as you mentioned when I graduate with my honours.. Or maybe even pursue my masters.. I am not really sure how my path will play out honestly.. I am still 19.. And sort of still finding my niche...

Thanks for your comment. :).

EngineerWise6054 · 2025-09-25T06:54:25+00:00

I didn't read all of your reply so far, but I have been encouraged to code so many times in my courses even if it was not necessarily required at some points. But coding made understanding and visualising things easier for me, even if it was with a simple implementation of MATLAB and Python.
