@curiousdannii, @PeterTurner. I am still unable to post new questions here after months now. The reason is the same... My questions were closed by an coordinated effort within the same hour to auto ban me from asking anything further.

I have asked repeatedly for feedback and further clarity as the reason for my questions being closed other than being unpopular with the majority here.... I'm still waiting for an answer.

christianity.stackexchange.com/q/93091/60347

That is one that was single handedly deleted by 1 mod.

christianity.stackexchange.com/q/93371/60347

And this is another perfectly good question that was also singlehandedly deleted by 1 mod without any reason given.

A reason for these singlehanded actions by 2 seperate mods is necessary so that I can fix the questions and be unbanned from asking more.

From everything explained to me on this site... These 2 questions are valid a should not have been hidden. Please clarify.

@ReadLessPrayMore You've received plenty of explanations previously. I've undeleted some comments although they were visible in the chat room that was created for the second question.

Neither question was deleted by a mod, they were automatically removed by the system. See christianity.stackexchange.com/help/roomba

@ReadLessPrayMore If you want to ask a new question, your best option would be to edit this one, as it has 0 votes. If it is edited and is on-topic then we can undelete it for you.

christianity.stackexchange.com/q/93049/6071

But remember to be respectful and inquisitive rather than combatative and dismissive to those you disagree with. And you should check the new comments policy (linked in the site sidebar)

@curiousdannii Both mods admitted to deleting them.

I will edit that one about the Children of God as well. But I need to also understand why the other 2 I linked above were not closed but outright deleted.

.....Looking at the edit log of the one of the questions I see that it was vote to be closed by having the death nail given by a mod Ken Graham on Nov 9th. Also on Nov 9th Peter Turner was the final death blow on the other q I linked above. Peter Turner also deleted 2 questions of mine the day before. This is exactly what triggered the auto ban. 3 deletions and 1 closing of my long standing questions in less than 2 days mostly by a single mod.

@ReadLessPrayMore Look at the question histories: "Post Deleted by Community Bot"

@curiousdannii If you look at the activity the closing and deletions done within 2 days... Nov8-9... you will find 2 questions deleted and 1 answer by Peter Turner. You will find also 2 non-new questions closed on Nov 9th by the deciding votes of Peter and Ken.

Also I have looked at my "Living God" Question and I have already edited it to be only applicable to Trinitarians. The questions asks for clarification using words and language only used by Trinitarians. I submitted this and had zero feedback.

@ペガサスSeiya OK. Through silent "trolling" in the Mathematics chat room I discovered frequent chat participant and Math.SE contributor Prof. Ted Shifrin who has a recording of his Math 3500 & 3510 course Multivariable Calculus and Linear Algebra. I'm starting there.

It's so great that Math.SE has REAL experts there, unlike in C.SE ☹️. So if I have question, I can ask Xander, TedShifrin and countless others.

BTW, I also discovered this great resource The Princeton Companion to Mathematics. Section 1.1 (pages 1-3) is very insightful, showing how Algebra, Geometry, and Analysis complement each other as 3 mathematical techniques.

Reminds me how in Christianity, studying God we also use 3 indispensable ways: Geometry is like Scripture (through picture/narration), Algebra is like Theology (through propositions), and Analysis is like Spirituality (approximation, through liturgy, prayer, and living it out: lex orandi, lex credendi, lex vivendi).

Roughly, Protestants emphasize Scripture (good in hermeneutics), Catholics emphasize Theology (good in philosophy), and Eastern Orthodox emphasize Tradition (good in liturgy, prayers, icons, and church history). Therefore when each group reflects, evangelizes and teaches you see very clearly their different emphasis. I strongly believe they complement each other and it's part of God's plan in guiding the Church throughout history.

@PeterTurner Didn't we used to have a JavaScript bookmark that can transform Bible verse reference into a full quotation? Just played with this which is official for the Mathematics chat room. Really cool ! I don't see why we couldn't have something like this that generates a pop-up to expand Bible verse with the option to specify a translation or even the interlinear Greek/Hebrew !

@GratefulDisciple I don't recall that, someone made a userscript for better formatting that I think is on meta

@PeterTurner I have seen some Christian website uses a script provided by Faithlife (from the company that makes Logos). When I'm tinkering on Javascript, maybe I'll take a look what we used to have and update it.

@PeterTurner Are you talking about this ? If so, I'm talking about something else, not markdown generator.

@GratefulDisciple Ted is one of the best Math SE experts in general.

Since you'll be learning LOTS of Linear Algebra you should check out his lecture uploads on YouTube about matrices

@ペガサスSeiya Are there more besides his Math 3500/3510 YouTube playlist?

@GratefulDisciple Only Ted knows the answer to that. I watched his matrices lectured when I was reviewing reduced echelon forms

@GratefulDisciple I happen to be gifted at geometry, particularly synthetic euclidean geometry, at least that's what I was told after getting first place in a university-wide math Olympiad

@ペガサスSeiya I'll ask him when the time comes. I'm good with those 112 lectures for now.

@GratefulDisciple since you'll be doing matrices, I recommend learning how to "think in 3D"

Geometrical interpretations of matrices, as being vectors, is real!y insightful

@ペガサスSeiya That's great, although I have to look up what "synthetic euclidean geometry" means; is it this one ?

@GratefulDisciple yes that's what it is

Geometry without any coordinates or formulae. Just raw intuition and logic

@ペガサスSeiya Of course. That's why I like Ted's approach: geometry based. That short 3 pages from Princeton Companion shows me clearly how geometry, algebra, and calculus are related.

@ペガサスSeiya My aim is to pick up the concepts needed for machine learning. I hope those 112 lectures will at least take me halfway there, while resurrecting my math brain neurons from high school and college days 😀.

@GratefulDisciple Linear Algebra and Multivariable calculus is at the heart of machine learning

It'll build enough of a foundation for you to study it in even more detail

@ペガサスSeiya Yeah, I figure that much, looking at this book. The other part not covered by Ted's lectures are statistics.

Also, I suggest understanding the geometric interpretation of the derivative. If you take the derivative of a curve at any point P, what you're really doing is drawing a line tangent to that point and measuring its gradient. For a general derivative formula of a curve, what you're doing is drawing infinitely many lines at infinitely many points and measuring how their gradient changes @GratefulDisciple

@ペガサスSeiya Thanks for the tip. Yes, geometric interpretation will be useful when reviewing differential and integration since I don't think when I took college calculus the approach was somewhat different.

Anyway, it should be fun to do geometry again. My high school was actually heavy in science and math. We went way further than typical high school geometry. My teacher had us do many problems related to conic sections. It was traumatic ☹️.

@GratefulDisciple doing conic sections will help you understand where objects such as parabolas, hyperbolas, etc come from

@ペガサスSeiya Yes. I cannot believe I'm doing this again. I thought I'm done with complex math once I got into Computer Science 😀.

@GratefulDisciple You can never be done with math as long as you're in STEM

I sometimes write code to solve specific types of integrals just for fun

@ペガサスSeiya I figure. Anyway, I'm going to attack this head on and conquer it! I can do it! (pep talking myself).

@GratefulDisciple are you on Math.SE yet?

If you want the community's help you gotta join first

@ペガサスSeiya Patience, bro. I joined already (my Math.SE profile). Once I'm comfortable with MathJax and finished Ted's course, I will be sure to contribute.

@GratefulDisciple you can contribute by asking questions about something you may be confused about while watching the videos

@ペガサスSeiya Sure, I will. It's a good thing that Ted is a really good teacher. I'll be using his textbook too, and do the exercises.

MathJax is simple enough, there's a whole tutorial on Meta SE about it if you need it

@ペガサスSeiya Yes. I actually used LaTeX for one of my CS courses, so it's not a completely new thing for me.

@GratefulDisciple yeah, I've encountered a lot of amazing teachers and Ted easily makes it to the top of that list. I wish he was there to teach me in person

@ペガサスSeiya What math classes are you taking now?

@GratefulDisciple all of them 😂

@ペガサスSeiya Are you sure? Topology too?

I had to take a few upper division math when I was in college. I dropped Topology after 2 lectures.

@GratefulDisciple haven't gotten to topology yet.

I don't know if 1st or 2nd year undergrads take topology

@ペガサスSeiya You're in Aerospace Engineering, right? What kind of math is specific to Aerospace?

@GratefulDisciple Linear algebra, calculus 2,3, differential equations, real analysis, analytical geometry, some control theory, discrete mathematics

@ペガサスSeiya If machine learning needs topology, I give up. That's too hard for me. Vector calculus is still okay.

@ペガサスSeiya I think the only one I didn't take was real analysis and control theory. I had numerical analysis (that was really fun).

(oh wait, maybe real analysis and numerical analysis are the same).

We're done with vector calculus for the most part

@ペガサスSeiya Great. I can ask you then :-).

@GratefulDisciple they're different

Real Analysis is more challenging than calculus. It is basically your first "real math" class

And it's super fun

@ペガサスSeiya You're right (just looked it up). I love numerical analysis by the way.

@ペガサスSeiya I would think Topology would be fun for you too, since you like geometry?

@GratefulDisciple yes. That's why I'm not scared of topology as most undergrads tend to be

@GratefulDisciple you might also do some PDEs depending on how far you go into calculus

@ペガサスSeiya I'm afraid so, although I don't like complex equations.

The other things I need to review for machine learning is algorithmic proofs. Ugh.

@GratefulDisciple Well, fortunately, or maybe unfortunately, most PDEs are impossible to solve analytically so you'll be doing numerical approximations for most of them anyway

@ペガサスSeiya Silver linings :-) Anyway this year will be an uphill battle for me.

@GratefulDisciple if you learn to enjoy mathematics it won't be such a tough time

@ペガサスSeiya Yeah. That's the idea. Gotta enjoy it. Maybe I will, after Prof. Ted's class. I really like his way of teaching. And the classroom interaction helps too.

One benefit I have of having no family or friends is that I can devote most of my time to mathematics. That's why I'm good at it, not just because I'm mathematically talented if that's even true

@ペガサスSeiya I'm sure you are talented. And you're in Japan too, that must help. BTW, isn't it past midnight in Japan now?

@GratefulDisciple pro tip: when he talks about the 3-dimensional space, a good way to visualize that for yourself is to hold three pen in your fingers orthogonal to each other and then pretend like they're the axes

@GratefulDisciple it is 1:05 AM yes

@ペガサスSeiya Thanks. I'll remember that.

Gotta do some work. TTYL.

@ペガサスSeiya Found Ted's course homepage for his Math 3500 and Math 3510 that contains syllabus and homework assignments.

Besides his textbook he recommends How to Think Like a Mathematician by Dr. Kevin Houston who has his own website and YouTube site.

@Matthew Then you'll have to explain to me what, specifically, you were referring to there.

@Matthew That is pulling Jesus' words completely out of their context. In John 3 he is not talking to Nicodemus about the Creation stories in Genesis. He is talking about our need to be born again. This is something we must do on earth. Once we have gone to the spiritual world, it is too late. There is no warrant to rip his words out of their context and apply them to a completely different issue, which is biblical literalism vs. reading the Bible spiritually.

This is a persistent failure of Protestant doctrinal argument. It continually rips individual Bible verses out of their context, and applies them to things that have nothing to do with what Jesus or his apostles were talking about.

@Matthew Epicureanism? I have no idea what you're talking about.

@OnlyTrueGod Perhaps it would help for you to read up on what scientific method is:

Wikipedia: Scientific method

@ペガサスSeiya Since we invaded your Mathematics chat with Christianity, I suppose it's only fair that you should invade our Christianity chat with Mathematics. :-P

@LeeWoofenden That's the mainstream view as well. At least we agree on this. Aquinas then take that teaching as one of the modes of God's presence in the world: because God is the ground of created beings and the sustainer of created beings, He is in fact closer than our mind to ourselves.

@LeeWoofenden Did Adam (Genesis 2) really exist? Was he the first human to exist? Is he the father of all humans?

@LeeWoofenden If you (and Protestants in this room) want to really know Catholic's own teaching on the Eucharist, here's an excellent lecture about it: Entering Into Christ's Passion: The Mass as a Sacrifice.

I host the MP3 temporarily here so you don't have to deal with SoundCloud's horrible media player.

I also host the handout temporarily here.

@LeeWoofenden I'm genuinely curious what you think here - not what a Wikipedia article claims about the scientific method.
