AI testing: The Bad…Time loops, tech support quirks, and drift

The PolyBlog
April 18 2026

By now, most people have seen some form of AI crop up in their tools. The most obvious one is Google’s search engine, which provides results from its AI mode first in the list. You can go pretty far with that prompt, even asking for image creation, although that’s a terrible place to create images (full imaging tools aren’t really available in AI search engine mode).

In my case, I’ve used it for some research here and there, often against a framework I had in mind. More recently, I’ve had it helping me “test” some frameworks. I design a framework for something I’m building or writing, I outline it and paste the outline into AI, and ask it to challenge the framework from the perspective of say gender equity, under-represented groups, or literacy levels. Something more than a grammar check, something less than a full AI partner. When it’s done, I decide if I want to change anything in my approach.

But I’ve discovered some recurring oddities. Not necessarily bugs, just aspects of LLM-based tools that attempt to translate what I’ve said into something concrete.

Time Loops

About three months ago, I was testing Google’s tools to create an image. I eventually moved to ChatGPT to do the same. And both tools had the same problem.

I input a bunch of prompts. Created some sample images. Iterated a few things. All good. Then I told it to “tweak the image” in a certain way, and it said, “Okay, here you go.” But it was the same as the previous image. There was no “change” or iteration.

Okay, I thought, random glitch. Please regenerate the image with the following changes. Enter, whirr, ding. Same image. Huh?

I would then tell the AI that it gave me the same image again. Apologies, whirling indicator, bam! New image, same as the old. No matter what I did, it would not give me anything else.

It felt like a giant glitch. Or Groundhog Day. No matter what I did, same result. I couldn’t get out of the loop.

At the time, I had NO idea what was happening. Was it me? Was it the AI? Was it my browser?

I now realize it’s essentially a memory issue. Each chat in certain tools has an amount of “context” memory built into it. Once that’s full, loops start happening. Things bog down. In some tools, it will say, “Hey, I need to compact, okay?” and it will crunch your chat and go, “all ready!”. Except you have no control over what it ditched. Images perhaps? Instructions you definitely needed it to remember? Gone. In other tools, it compacts without even telling you.

The AI experts advise that where you had it generate a lot of “assets” (pictures, documents, etc.), it’s better to start your next phase with a clean prompt. You can cheat, though … if you ask an AI tool for a “handover” note, it will generate one you can prompt into the next chat, while it quietly fades into an ignored chat window. Waiting to see if you ever come back.

Google AI mode and ChatGPT seem terrible for this. I hit a lot of loop walls quickly. Gemini wasn’t so bad, but I think that was one of the ones that just compacted on its own. I actually prompted it a few times to save just to be safe. Claude, by contrast, doesn’t seem to have ANY of that happening. It hasn’t got stuck in a loop, and I haven’t seen it compressing/compacting/deleting anything yet.

PolyWogg 0, AI -25.

Technical support

One use case people recommend for AI is technical support. I’ve had four experiences using AI as technical support, and it has done a couple of things okay-to-well, and bombed on others.

The first bomb was on support in a program called mIRC. The IRC part of that is for Internet Relay Chat, and mIRC has been my go-to tool for online chatting since the late ’90s, when I used to be really into it. I have a couple of specific uses for it now, and I installed a couple of plugins recently to automate some stuff. Great, except they didn’t work QUITE the way I wanted, and the default display was in 9-point font. So, I asked ChatGPT how to tweak the mIRC settings for what I wanted.

One of the first things I told it was that I was using version 7.8.3. It has changed interfaces over the years, as well as command structures, so old commands won’t work; just like the voicemail messages say, “Please listen closely to the following options as our menu items have changed.” Okay, ChatGPT said, in its oh-so-confident way, that setting the display font to 16 points was super easy. It gave me a simple command, I entered it, and Bam! Error message. mIRC had no idea what that command was.

I told ChatGPT, it said, “Oh, right, sorry, yes, it’s done THIS way.” Another command, same error. “Oops, let’s do it through the menus, guaranteed to work. Click on DCC / Options / Display / Fonts”. Except there is no DISPLAY option under options. The menus have changed. Took me a while to find where fonts were. Made the change. No help really from chat, I just found the setting. Great.

Except no change. It would change the font for the chat window, but not the popup windows that I needed to tweak. Back to ChatGPT. Reminding it that I was in 7.8.3. Oops, it told me, the instructions were for version 4.3 or something archaic. What? Why? I specifically told you NOT to show me guesses, and to ONLY show me solutions that were validated for 7.8.3. It politely informed me that it hadn’t guessed; it had “INFERRED”.

And thus began my long descent into a deep rabbit hole with AI along for the ride, digging small tunnels ahead of me.

I knew the change could be done, that it wasn’t rocket science, and that I wouldn’t figure it out on my own. I knew just enough to know that either the default font or the plugin font was set too low. No other way for it to be wrong. I knew, therefore, Dr. Watson, that I could either fix the original setting, find a way to override the setting automatically, find a way to change it manually after the fact, or ignore it completely. As time wore on, that last option grew increasingly attractive.

To be fair, mIRC isn’t exactly a commercial application like Microsoft Word. It doesn’t have millions of users. And a user plugin within mIRC? That has even less information about it.

Yet each time I asked a question, the AI tool would say, “Oh, I know how to do that!” Except it never did. It couldn’t find where the default font was set, although I later figured out that it wouldn’t matter, it was the plugin font that was the problem. And it couldn’t figure out how to change fonts AT ALL. Nor could I. I opened EVERY file that came with the plugin. Lots of stuff for settings in the pop-up window, but nowhere where it had a font setting. It seems to be hardcoded in the plugin, alas.

I was undaunted. I knew that if I couldn’t do the first two options, I could at least set it after it loaded. Because I could go into the menu, choose Options / Preferences / Fonts / Font choice. Or something equivalent. It took about 5 clicks to get to where I wanted to change the font. But then if another window opened, I had to edit that one too — another 5 clicks.

None of the options AI suggested worked. Auto-load commands, mIRC scripts — none of them worked — and mostly ended up with the AI tool telling me, “Oh, it would have worked if you were using an older version.” WHICH I TOLD IT NOT TO DO! Grumble, grumble.

I found a workaround — I forced the font menu onto the taskbar manually and then told it to stay there forever; now when the pop-up shows up in 9-point font, I can click the taskbar, the menu opens, I change the font to 16 to 20 points, and it’s done. Super easy, two clicks.

Drifting back to shore

This is a newer version of the loop problem. At least, it seems like it is the same sort of error.

I was trying to get Claude to do an image for me. I wanted to create a badge, with an embroidered edge. All of the AI tools take different approaches to images; some work in specific types of image scenarios, others in different scenarios, and others? Well, some don’t work at all.

Claude NAILED the first part of the badge problem. It gave me a perfect ring on the first try, which none of the other tools did (it uses SVG vectors to handle the geometry, hence why it was so accurate). But when it tried to do the embroidery, it failed completely. Nothing it did looked like embroidery.

I scrapped that idea, moved on. About 40 minutes later, out of nowhere, its attempts at embroidery showed up again in the margins. I was like, “Huh? Did I paste an old prompt?”. So I asked it why it included embroidery in that version. It told me because I asked for it earlier, and the algorithm forgot that I said no to it, so it went back and did it again. It had “drifted” back to the earlier setup. A little weird, so I had it add a prompt component that said very clearly, NO EMBROIDERY ELEMENTS. About 20 minutes later, working much further down in the model, the embroidery attempt came back. I checked the prompt; it clearly said no embroidery. So I asked again, “How?”.

This was a second type of drift. It had analyzed the prompt. And because I had asked for embroidery before (positive inclusion) and now was excluding it (negative inclusion), the fact that I had mentioned it at all was interpreted as positive inclusion. It ignored the “NO” part. I suddenly felt like I was working at Foreign Affairs back in the old days of TELEXes where you couldn’t afford for a word to be missed so you would type NO/NO to make sure one of the “NOs” made it through. I didn’t try that with Claude, because it was now a VERY long chat, Claude was getting on in digital minutes/years, and showing signs of confusion. I reset and started with a new chat, no mention of embroidery. It never showed up again.

I couldn’t find a way around it, other than using new chats. Not sure that’s a win.

That’s the bad news. I was going to write about the tips it gave me for GIMP, but that’s a mixed bag, not all bad. And what really excites me is all the good things it’s done for me. That’s the next post. 🙂

GIMP lesson 003 – Launching GIMP

The PolyBlog
January 25 2026

Since I started this “learning exercise” for GIMP almost 2.5 years ago, and the training was already a year or two old at that point, my lessons are a bit jumbled up. Not only that, it was designed for v2.6 of GIMP, and the current version is 3.0.8. A few versions later, to say the least. As such, I’m going to have to do a bit of searching from time to time to convert certain steps over into “new GIMP”.

When I started, I looked at how to save images and optimize certain file types for size. Now, I’m stepping back for a moment to see the “start-up” options to see if there is anything I should tweak or customize.

One of the first tweaks is to personalize my workspace palettes. It’s a decently long list of options of things to add to the default desktop:

  1. Tool options *
  2. Device status *
  3. Layers ***
  4. Channels ***
  5. Paths ***
  6. Colormap
  7. Histogram
  8. Selection editor **
  9. Navigation
  10. Undo history *
  11. Pointed
  12. Sample points
  13. Symmetry painting
  14. Colors
  15. Brushes **
  16. Paint dynamics
  17. MyPaint brushes
  18. Patterns **
  19. Gradients
  20. Palettes **
  21. Fonts **
  22. Tool presets
  23. Buffers
  24. Images *
  25. Document history **
  26. Templates
  27. Error Console
  28. Dashboard

The ones with asterisks are part of my default choices; a bunch of the others will come in handy when I eventually get to the stage of doing astro processing. The ones with one * are on the left sidebar; the ones with ** are on the top right; and the ones with *** are on the bottom right.

After that, you either open an existing file (FILE / OPEN) or create a new one (blank or from an existing template as FILE / NEW).

What I learned today

I learned how to set up my desktop for access to my most common “palettes” (submenus and tools) and how to create a new file.

An addendum to my learning plans

The PolyBlog
January 25 2026

I am not quite sure how I didn’t think of this at the time, but when I was going through all my plans for formal learning, I completely missed a discipline. I was thinking about something earlier today, and it suddenly occurred to me that I had missed it.

I have mentioned previously when talking about performance measurement that one of the areas I am interested in writing about is around libraries. Part of it is PM; part of it is story-telling; part of it is management; part of it is municipal oversight. How libraries organize themselves and tell their citizens how they are performing, basically.

And yet, for some reason, it didn’t occur to me to include a Master’s in library studies as part of my possible plans? I’m thinking of a whole book on it, and I didn’t link the two? I considered doing an MLS degree previously and didn’t think of it as a possibility? Weird.

So, I checked through Canadian offerings. The last time I looked at MLS-like degrees, it was probably the early ’90s, as I was finishing my undergrad at Trent. Thanks to AI offerings, the list was narrowed down pretty quickly — there are eight MA-level programs in Canada that are certified by the American Library Association (ALA). All of them are tied to Information Studies/Science/Management now.

Four are relatively easy to eliminate as being primarily in-person:

  • Université de Montréal: In-person and totally in French, pass;
  • McGill University: In-person, pass;
  • University of Toronto: MA in “information” with a concentration in Library & Information Science…alas, only in-person, pass;
  • Dalhousie University: MA in information, but only in-person, pass;

The University of Ottawa has an MA in Information Studies which is bilingual and in-person. I could consider it, but a quarter in French doesn’t seem likely for oral comprehension, my weakest area. I’m going to pass.

UBC has a primarily in-person program, with some distance education stuff. Doesn’t really excite me, and I don’t want to do a semester there. Pass.

That leaves two that offer fully online options.

Option 1: Western

The new kid on the block is Western. They have the most structural options as of this month, with full-time and part-time combos with online or hybrid. It is a Master of Library and Information Science.

The program structure has five required courses and ten electives. For the required courses, four are standard intro courses around the broad areas of the program, including Perspectives on Library and Information Science; Information Organization, Curation and Access; Information Sources and Services; and Managing and Working in Information Organizations. The fifth is Research Methods, which I might or might not be able to get out of, depending on whether it is RM specifically to libraries or qualitative methods in general.

I took a peek through some of the “main issues” that the different parts of the program addresss, including:

  • The needs of various stakeholders and agents / intermediaries / end users in information organization, curation and access
  • Intellectual property, copyright and access, both for individuals and institutions, and the rights and claims of various stakeholders
  • Materials and services for children and young adults
  • Information literacy
  • Readers’ advisory
  • Strategic planning and collection management
  • Other work activities covering advocacy, community development, marketing

Which sounds good. Until I look at the list of actual courses from which I would choose my 10 electives…and only see about 5 that interest me. A couple might be badly named, and the sub-materials might be quite interesting. They have a research option, but it’s only one credit/course.

As I look at it all, I am reminded of my interest in legal studies…Do I need a formal structure to do this type of work? I don’t need the degree itself. And I haven’t even considered that it’s about $12K for a full year’s tuition.

Option 2: Alberta

Alberta has apparently offered a long-standing part-time online option. It is all done asynchronously, which wasn’t entirely clear for Western, but would obviously appeal to those who are working and thus can time-shift their school work. Because it is part-time, you are limited to 2 classes per semester. They have an option where you can do a thesis, but only if it is in-person/on-campus.

Otherwise, you have to do 13 courses:

  • 5 core courses that are similar to Western (Foundations of Library and Information Studies; Organization of Information; Reference and Information Services; Leadership and Management Principles for Libraries and Information Services; and Introduction to Research in Library and Information Studies);
  • 2 IT-related courses (there are five main ones and two special topic ones to choose from, any would be fine);
  • 6 electives; and,
  • Capping “portfolio”.

    For the electives? There are 27 courses to choose from, and some of them sound, well, awesome:

    • Special Topic: Management of Financial Resources
    • Services in a Culturally Diverse Society
    • Intellectual Freedom and Social Responsibility in Librarianship
    • Instructional Practices in Library and Information Services (pedagogy and teaching)
    • Multimedia Literacies
    • Publishing
    • Issues and Trends in Public Librarianship
    • Storytelling
    • Materials for Young Adults
    • Canadian Literature for Young People in Schools and Libraries
    • History of the Book
    • Advanced Scholarship and Research

    And then the tuition hit comes. About $17K minimum for 39 credits/13 courses. Doable still, and way more interesting than Western. And, I think, I would even do it before considering more law / legal studies. But an MFA is still more likely.

    A cool rabbit-hole, not completely explored yet.

    2026: L is for Learning

    The PolyBlog
    January 18 2026

    I find this post fascinating in multiple ways. It seems simple…what will my learning focus on in the coming year or two?

    Except for just about every one of my A-Z headings, they involve learning in some way.

    Except that I recently went through a huge analysis and research project to look at very specific types of formal educational learning that I might undertake, representing hours of work on my part to figure out just what was out there in the fields that interested me.

    Except even when I look at the long list, which ones will I do simultaneously, and which ones will I do sequentially? Or as fallbacks if the others don’t happen?

    Except that what I thought was my likely priority is not the list when I have to rank very different things against each other.

    Let’s go…

    Rebuilding / summarizing my list

    Just to help keep things straight and not confuse formal education with simpler task-oriented learning, I’ll divide the list into three parts:

    • Formal certifications
      • Masters of Fine Arts / Creative Writing: Dalhousie/King’s College, UBC, Algonquin, Athabasca (BA Communications studies or BA English, or MA as Interdisciplinary Studies — build your own MFA degree … Writing the self; creative non-fiction; digital storytelling; narrative possibilities; and what I tell you may not be true (autobiography in a different lens)
      • Education: Athabasca (M.Ed in Distance Education)
      • Law: Redo old program, update old program (criminal, constitutional, contract, torts, property, ethics, dispute resolution, access to justice), Athabasca (Interdisciplinary … $$$), Carleton MA (Legal Studies … zzz), Coursera, Royal Roads MA (Justice Studies …. $$$$)
    • Utilitarian skills
      • Astronomy: Algonquin (2 courses), The Great Courses + Coursera, YouTube, books
      • GIMP Processing: Online downloaded course
      • 3D Printing: YouTube, local experts
      • AI Software Development: Algonquin, online programming training (app development)
      • Photography: SPAO (formal and rec), Great Courses, YouTube
    • General interest
      • Baking, cooking, pastry arts: Algonquin
      • Mythology, sci-fi, world religions, world literature: Algonquin
      • Kayaking: Clubs
      • Psychology: Athabasca (BA), Algonquin (1)

    Prioritization

    For the training and learning options, I can apply the PACE approach to prioritizing:

    PRIORITYALTERNATECONTINGENCYEMERGENCY
    OVERALLGIMP (course)Astronomy (TGC)MFA (Dalhousie)Psychology (TGC)
    1. FormalMFABA EnglishM.Ed (Distance Education)Law (text redo)
    2A. Utilitarian – AstronomyThe Great CoursesCourseraYouTubeAlgonquin + books
    2B. Utilitarian – Apps, softwareGIMP (course)3D printing (local)Programming (iOS/Web)Programming (PC)
    2C. Utilitarian -PhotographyThe Great CoursesYouTubeHenry’s +SPAO
    3A. GeneralCooking (online)Cooking (recipes)Baking (recipes)Pastry (local course)
    3B. PsychologyThe Great CoursesAthabasca (BA)Algonquin courseTextbook
    3C. Mythology, historyThe Great Courses – MythologyAlgonquin course – MythologyAlgonquin course – World literatureVarious – World religions

    As I said, I did not expect my priority to be GIMP over Astronomy (TGC), the MFA itself at Dalhousie, or psychology. If I leave work with a large education allowance, the MFA would jump up the list as a formal commitment. But perhaps my thoughts on the priority is more driven by what I can do this year. I could, in theory, start on the MFA, but there is already a lot going on in the next year in our household with multiple health issues, changes in lifestyles, etc. An MFA on top of that seems like a lot. I also didn’t consider whether something that was an “alternate” for formal (like the BA English or M.Ed.) might go above the psychology too. The rows do rankings by column, but the columns don’t necessarily rank evenly from row to row.

    If I look at my “learning” list from previous years, there are a number of little things on there that didn’t make the above list. Chair yoga, origami, etc. Nothing “big” enough to make the overall list. But something to consider on my future tracker if learning is limited to these headings, or will also reflect my NF reading, other hobbies, etc.

    In the meantime, I can start learning GIMP.

    Exploring learning options for astronomy

    The PolyBlog
    December 18 2025

    I have been posting over the last week or so about possible study options for various topics in my retirement. Lifelong learning, and all that. One area that I would be interested in is astronomy, although I have some challenges figuring out exactly what form that study would take.

    Formal Canadian degrees

    I used a few index tools to look for astronomy or astrophysics programs, and I found about 15 or so options in Canada. I don’t need the degree, so I could take it from anywhere, but the prices frequently go up when you cross borders to be an international student.

    None of the options in Canada are particularly great for online completion or even my situation.

    Ontario Tech University (Oshawa) has four variations of Bachelor of Science degrees (AP, physics) or Bachelor of Science and Management (AP, physics). Queen’s (Kingston), Western (London), York (Toronto), St. Mary’s (Halifax), Waterloo (Waterloo), University of Calgary, and University of Alberta (Edmonton) all have Bachelor degree options. Waterloo throws in a minor, Western offers a specialization. All of them are generally four-year degree programs, standard science programs and curricula. I could probably do a series of AP / astronomy-only courses, skip the electives and other courses, as a mature student or something. But I’d have to do the application process, share my high-school transcripts and diploma and they wouldn’t care that I did an undergrad or grad degree because neither were in science.

    Which is also the problem with two master’s programs — Queen’s and Waterloo (or the Ph.D. @ Queen’s). I have a friend who did an Medical degree at age 40 at one of two universities in Canada that have med degrees that don’t require a science undergrad to get in (Western and Calgary, she went to Calgary). Neither the Queen’s or Waterloo programs let you in without a science undergrad. Preferably with some solid algebra and calculus at the university level. My 99% in high school calculus was enough to bypass calculus at Trent for econometrics, but probably wouldn’t be that useful 40y after exiting high school.

    So not online, four years in total, AND I’d have to figure out a way to take courses without all the extra science-y and math-y stuff.

    Not much of an option.

    Coursera has entered the chat

    I took two courses previously through Coursera, including one on meta-literacy and one on video games from a cultural studies perspective. The meta-literacy was alright for the time; the video game one was remarkably substantive (I thought it would be a bird course, but it had some decent academic lifting going on).

    Since then, Coursera seem to have altered its model a bit more, or at least the money and credentials side seems to have shifted. There are fewer full-credentialed programs than I remembered, as I thought there were more diplomas and stuff available, particularly for computer programming and such. I also thought there was a couple of science programs available, although I didn’t remember exactly how the “Coursera-hosted courses that are cross-listed with full universities” model worked. The video game course was offered by the University of Alberta for full credit if you wanted to go that route. I didn’t at the time. Now, I wanted to know what was available.

    Basically, there are about 128 astronomy courses available in Coursera in English. At least, that’s what the search engine on Coursera itself says. Unfortunately, if I search for astrophysics, I get a slightly different total AND some of the courses are supposedly in English but as I scan through, some are either in another language (like Italian) but with AI generated dubbing (pass) or they’re in another language with subtitles (also pass). If I use the astronomy search results only, it tells me there are:

    • 47 beginner classes;
    • 36 intermediate classes;
    • 18 advanced classes; and,
    • 26 mixed-level classes.

    With 49 different educational partners in total, of which 36 have either only 1 or 2 classes offered. For recognizable names, CALTech offers 2, Yale 5, Rice 13, and, drum roll please, the University of Colorado at Boulder has a whopping 27 classes. WTF? Here’s their list:

    I confess that the group of courses is NOT what I was expecting…three courses on journalism, politics and the nature of the space race? Two general-interest / introductory courses on the universe are “normal”, I expected those. I did NOT expect 4 courses on optical design elements (presumably linked to telescope mirror quality) nor 14 on spacecraft design and operations.

    Sooo, that’s not the right route. I went back to the original list, exported the list of courses to Excel, ran some reconfigs on the data to put it in a table, and voila — 128 entries of which 4 are fully free, 59 have a free trial, 64 have a “preview option”, and 1 is just simply “new”. The time durations and levels are a bit more granular:

    • Beginner: basic course of 1-4 weeks = 14 courses, moderate investment of 1-3 months = 32 courses, and serious commitment of 3-6 months = 2 courses;
    • Intermediate: basic course of 1-4 weeks = 15 courses, moderate investment of 1-3 months = 18 courses, and serious commitmetn of 3-6 months = 3 courses;
    • Advanced: basic course of 1-4 weeks = 9 courses, moderate investment of 1-3 months = 8 courses, and serious commitment of 3-6 months = 2 courses;
    • Mixed: basic course of 1-4 weeks = 1 course, moderate investment of 1-3 months = 23 courses, and serious commitment of 3-6 months = 1 course.

    Of course, obviously, I wouldn’t be taking them all. I just wanted to do a deeper dive to know if it was a viable option. Most degrees are 10-12 courses across a spectrum, and while I’ll have to figure out which ones are basically variations of the same course, I think there are a few that are pretty good starter ones for me to consider.

    So, about that cost thing

    There are four “free” classes, including Astro 101: Black Holes (University of Alberta), Space Medicine (Duke University, Statistical Mechanics: Algorithms and Computations (École normale supérieure), and Imagining Other Earths (Princeton). The first and last ones could be interesting.

    The rest? The new, or at least current, Coursera cost structure is very different from what I expected. As I mentioned earlier, I noticed fewer degree programs, and previously, I was only looking for free courses to audit or pseudo-audit. However, I basically have three ways to consider the classes, and none of them would seem amenable to anything to do with an educational allowance under WFA from work.

    Option 1 is to pay per course — most are about $70 each. Some keep the costs down by marking things with AI, which makes me a bit leery. I was also surprised to see some courses showing up as being in English but actually in a language like Italian with AI-driven dubbing. Nope. But $70 is generally okay as a start. The ones with free trials or previews have decent “look inside” options to see what the course looks like, type of modules, etc.

    Option 2 is to pay per month — somewhere around $80 or so Canadian, but as an “all you can eat” buffet of courses. Of course, the limit for yourself is more one of time and availability. I’d love to start courses immediately but I wouldn’t have the time yet.

    Option 3 is actually better if I were fully retired. If you pay for the year, the price drops to about $560, or about $48 per month (instead of $70 or $ 83). That’s not bad — a year’s tuition for 3-4 classes compared to $280 doing them individually doesn’t look as good, but if I were to do 3-4 at the same time or a series of ones that are 1-4 weeks, I could crank out a few and come out ahead. Basically, if all the classes were only $70 each, I’d need to do 8 in a year to come out ahead. Although some of the classes are NOT only $70…technically they START at $70, but some go as high as $120 or $130. I think I’ll be tempted to try a couple of the ones I want for sure, and then figure out afterwards how many I might want to / can do at a time.

    Soooo, I have a list of 128 courses that are nominally “astronomy or astrophysics” related, and I might pick 10-20. Or I could go a different route.

    The Great Courses

    I also wanted to see what I remembered from the offerings on the program, “The Great Courses”. I’ve done part of a psychology class with them, as well as some photography work. And when I run “astronomy” through their list of offerings, I get 30 courses. But they are not the “same” type of list as that of Coursera. Although maybe it isn’t quite as simple as that.

    For the list of 30 courses at The Great Courses, there are ten that are pure astronomy:

    1. Understanding the Universe: An Introduction to Astronomy, 2nd Edition 
    2. My Favourite Universe 
    3. Introduction to Astrophysics 
    4. Life in Our Universe 
    5. Black Holes Explained 
    6. The Life and Death of Stars 
    7. Dark Matter, Dark Energy: The Dark Side of the Universe 
    8. Experiencing Hubble: Exploring the Milky Way 
    9. Experiencing Hubble: Understanding the Greatest Images of the Universe 
    10. What Can the James Webb Telescope See? 

    Four general intro classes, some stuff on black holes and stars, a bit on dark matter, and then moving into astrophotography and imaging of the big space telescopes. Not quite enough rigour for me on the formation and structures, but it’s a start.

    The interesting thing is that they have 14 “history” courses that include some bits of history “of” and “with” astronomy:

    • The Remarkable Science of Ancient Astronomy 
    • Great Heroes and Discoveries of Astronomy 
    • The Birth of the Modern Mind: The Intellectual History of the 17th and 18th Centuries 
    • The Olmecs: Mesoamerica’s Mysterious First Civilization 
    • The Queen of the Sciences: A History of Mathematics 
    • The History and Achievements of the Islamic Golden Age 
    • Secrets of the Occult 
    • The Middle Ages around the World 
    • Maya to Aztec: Ancient Mesoamerica Revealed 
    • Conquest of the Americas 
    • Greece, Rome, and the Birth of Western Philosophy 
    • Introduction to Greek Philosophy 
    • The Other 1492: Ferdinand, Isabella, and the Making of an Empire 
    • The Greek World: A Study of History and Culture 

    And then there are six other classes that I pegged as “science”:

    • Radio Astronomy: Observing the Invisible Universe 
    • The Joy of Science 
    • Great Ideas of Classical Physics 
    • Chaos 
    • Einstein’s Legacy: Modern Physics All around You 
    • Change and Motion: Calculus Made Clear, 2nd Edition 

    Now, what did I mean by “Coursera doesn’t have the same courses”? They do have the introductory astronomy classes. And I’m sure they have courses on ancient history, including Greece and the Roman Empire. But Coursera doesn’t consider any of those history or mythology courses to have anything to do with astronomy. But the material absolutely does, of course, as the growth of various nations around the world developed science and philosophy together, often intermingled with religion and politics as well. All were trying to answer the fundamental questions about the nature of our existence in relation to the broader universe.

    Once I retire, I’ll have to narrow the options further, but at least I have a good starting point. Which, I realize, is what I’m doing right now…trying to figure out some of the options. I’m seeing which ones are viable so that if/when I have to make a decision, it will be clear what the options are to consider. I’ve even ruled a few things out as I went, which is huge. Enough to get my brain around it at least.

    A couple more areas to look at…
