Brilliant Tutorials in Mathematics and Computer Programming

The name is the attractor. I certainly want to be brilliant, if only in my own estimation though not the world’s. About 272 days ago, we both signed up and paid $161.88 each. She is still mad at me because she paid for something that does not work. I pointed out that they say that they are hiring and proofreading high school math is exactly her kind of job. So, that ball is in her court. I still work the problems, even when the problems have problems. 

I usually work at night and sometimes I have to skip one (even two) sessions, but I earn battery charges that carry me over. 

So far, I have completed series in elementary algebra, geometry, and calculus in addition to Probability & Chance, Functions, and Vectors, and large sections of logic, data analysis, and some others. A few, I began and chose not to pursue. The lessons on Digital Circuits and Circuits are waiting for me to make time to haul out the breadboarding kits. (I want to see their answers.) 

The reviews are nice exercises at bedtime. I do most of the work in my head. Some got complicated and required pen and paper and some of those are long tutorials, which, if I quit, I lose my place and have to start over. (About the third pass, I have memorized the first several answers.) It’s bedtime reading. I do enjoy the learning.

Find sin(a+b). 

I worked this through over three nights and was able to conceptually integrate the lesson and the proof of the formula. 

The Pythagorean Theorem has over 300 published proofs (one of the them by Pres. James Garfield). The proof in Euclid’s Elements is one of the most complex and demanding and least intuitively obvious presentations of this well known truth. So, too, with this demonstration of the measure of the sines of two adjacent angles. Nonetheless, after several repetitions, I found it elegant.

But not everything works that well. I ran into bugs in their tutorials for polar coordinates and for modulo arithmetic. As I told Laurel when she discovered other errors, all that is required is to document everything with screenshots, write out a descriptive narrative to show your work, and send it to them. 

51 mod 3 = 0 and also 51 mod 17 = 0.
And 51 mod 2 = 1.
But not here.

The Polar Coordinates maths are inverted.

The iPhone can be a barrier. I stopped working in Python, computer science, and AI because it is easier on the keyboard and I seldom sit here before going to sleep. So, I do what I can in bed and let the rest slide until I can have some daytime hours free for fun and games. I did finish the packet on Algorithmic Thinking.

ArmadilloCon 50: 2028 (My Proposals)

This was my cover letter to the FACT Board:

Dear Fen:

Attached as a PDF are some ideas that I have for the 50th Anniversary ArmadilloCon in 2028. What actually gets done will likely be much different from these points of discussion and that is the reason why the planning should be begin as soon as possible. Here in Texas we are often “fixin’ to start”—not actually doing the thing but knowing that we need to get ready to. 

I have been going through our archives by editing the show URLs (schedule, speakers, etc.).

Just for instance:

https://armadillocon.org/d16/

https://armadillocon.org/d27/

https://armadillocon.org/d32/guests.shtml

https://armadillocon.org/d36/writers.shtml

Then, I found the Con History on the FACT website: 

https://fact.org/con-history/

The array of past guests of honor, attending authors, presenters, speakers, and events is astounding and has analogs with every other long-lived SF/F gathering within the galaxy of science fiction, fantasy, and alternative fiction. That all comes with a burden of responsibility to the future.

LLP,

Mike M.

This was the proposal that I submitted.

ArmadilloCon 50 in the Year 2028

Submitted to the FACT Board October 11, 2025, 

by Michael E. Marotta (uszik11@gmail.com; books78640@gmail.com)

FACT should form now a convention committee for ArmadilloCon 50. It will of necessity change over the next three years, as people come and go. Open discussions should start now. A website, discussion board, Substack, or whatever should be launched now to facilitate interest and stimulate enthusiasm, by encouraging suggestions. Put out a call to FACT members to volunteer for the 50th Anniversary Committee, perhaps limited to eight (if that many are interested.)

Convention Theme: 

The Psychohistorians. What are our future histories? It is easy to imagine many paths of development given some selected assumptions. However, Isaac Asimov’s conception of psychohistory was a science of applied mathematics. To be a science, a body of knowledge must be falsifiable, which means that it must offer predictions from outside its own establishment.

Convention Theme:

Frankenstein. Arguably not science fiction, the story does carry the program of The Other, whether from another planet or a parallel universe, whether a robot or a dragon, to ask, “What is human nature?” Perhaps quintessential to science fiction, Frankenstein is the story of an invention gone wrong. 

Convention Theme:

Alternate sciences. Allowing that even magick has rules, what are the frontiers of science (or sorcery) that can provide the set and setting for a story? 

Attendance Goal: 1000 registered at $100 each.

Panels and Tracks

Artist Track — We talk a lot about the craft of writing and the markets for publications but we seem to pretty much leave artists on their own. We do have plenty of artists around. Perhaps a track for them or a couple of panels for media and markets would add a dimension to the convention.

Copyrights and Copy Wrongs

I heard that one of the publishers of anthologies failed to actually register their copyrights for their authors and many works were taken without compensation. The USA joined the Berne Convention in 1985 and that treaty gives authors and other creatives their primary rights but those are only the right to sue after the fact. In the USA we still should register with the US Copyright Office. Unfortunately, that office is now closed. What can an author or artist do to protect their intellectual property ?

Social Consequences of Life Extension.

As we all live longer and ever longer, do we push out to seek those famous new frontiers or do we become more conservative, less willing to take risks, more distrustful of change?

TV and Film Writers You Need to Know.

Laurel and I watched an episode of Castle, about a mystery writer who insinuates himself into police investigations, a known trope in crime fiction. In this story, the non-real writer, Rick Castle, is playing poker with Stephen J. Cannell and James Paterson. I knew Cannell from The A-Team and Riptide, etc., but not Paterson. Laurel knew Paterson but not Cannell.

Convention Publication

ArmadilloCon 100. Austin in the Year 2078. Ten flash fiction stories of 1000 words each by ten invited authors from our GoH roster (or others). Offer $100 each and see who is interested. 

Panel Moderators and Other Guests of Honor

Send out a Request for Proposals, asking writers and others to submit their bids to be at ArmadilloCon 50. 

Ahead of ArmadilloCon 50, we could engage some new practices and have the wrinkles ironed out for the big show.

A message board. At computer security conferences here in Austin, OWASP often puts up a flipchart on a tripod where people can leave messages for each other. At ArmadilloCon 47, I worked the Registration desk and on Saturday morning, someone wanted to leave a message for another attendee and I made note of that and kept that half-sized sheet until Sunday afternoon. Cleaning up, I threw it out. Then the recipient arrived looking for a message. 

A tech station for printing, etc. The hotel typically has its own workstation for guests, but those are notoriously insecure. This year, the hotel workstation was down for remodeling. Jonathan ran out and bought a tablet, but the team could not get it up and running properly. 

Convention T-Shirts. We have had Pegasus Publishing as a dealer for several years. They can handle our T-shirt production and sales. Moreover, they could have been selling prior year t-shirts for which, as I understand from a chance comment overheard in the last hours of the show this year, we have no interest and no market and just give them away so as not to be bothered with the extra inventory. 

Convention Coffee Cups. Reach out and see if LG Ceramics is interested. I believe that if they had five (and only five) Convention cups at the next show, those would sell out and create the market for the cups of the following year. Otherwise, these things can be ordered dishwasher safe and microwave safe from many places.

Having received the proposal but not having a motion to act on, the chair agreed to put ArmadilloCon 50 2028 in the Old Business section of the Minutes for the November meeting. 

I sent another email to the FACT Board, and cc:ed some of the past convention workers who might be interested, such as the FlashFiction coordinator.

Convention Publication

ArmadilloCon 100. Austin in the Year 2078. Ten flash fiction stories of 1000 words each by ten invited authors from our GoH roster (or others). Offer $100 each and see who is interested.

I brought my checkbook to the Board meeting and I was prepared to pay for the writers for this Festschrift but we never got that far into the discussion of the 50th Anniversary Convention because we ran out of time.

FRANKENSTEIN, RAYGUNS, AND BICYCLES

I read for research. This past Christmas break, I read formal philosophy. From 2021 through 2024, I read a lot of astronomy, several of those books cover-to-cover. But I do try fiction. I do not always succeed. I read at bedtime and therefore the sprints are short. Perhaps more to the point, I prefer to read authors who write better than I do and I have no patience for anyone who cannot outdo me because I know that I am not that good at it which is why I do not write fiction. However, as Montag said in Fahrenheit 451, inside each book is a man. So, I give the author a fair chance. 

At ArmadilloCon 47 this past September 12-14, I was working in the Convention Suite and two of the fen (not “fans”) were chatting. “Of course, I read Frankenstein,” said the one. Replied the other, “The 1818 or the 1819 version?” I was loading ice so I missed the rest, but I did check out two editions from the UT Perry-Castañeda Library. The book is nothing like the movies. (I have not seen the newest release from Guillermo del Toro.) 

• Frankenstein : the 1818 edition with related texts / Mary Shelley ; edited, with introduction and notes, by David Wootton. Shelley, Mary Wollstonecraft, 1797-1851, author.; Wootton, David, 1952- editor.
• The annotated Frankenstein / Mary Wollstonecraft Shelley ; edited by Susan Wolfson and Ronald Levao. Shelley, Mary Wollstonecraft, 1797-1851.; Wolfson, Susan J., 1948-; Levao, Ronald. 2012.

The proper title is Frankenstein; or, The Modern Prometheus. In my opinion, Mary Shelly failed to complete the analogy. Moreover, that context was not explored in any of the editions or criticisms that I found at the UT library. 

Prometheus (Forethought) was tasked by Zeus with creating animals to inhabit the Earth. His brother, Epimetheus  (Afterthought), gave all of them the strength, speed, agility, powerful talons, fangs, hides, horns, etc., etc., leaving Man with not much else. Prometheus gave Man intelligence — and fire. For that, he was chained to a mountain in the Caucasus and his liver was torn out by a vulture, only to regenerate overnight and be torn out again. We experience the tremors of his suffering as earthquakes. Mary Shelley did not carry through the many possible parallels. 

What does project to the reader is the dual nature of the monster. He is completely innocent, teaching himself to understand language, speech first and then writing. He discovers music, first in birds then from the old man in the cottage. He is vegetarian, subsisting on roots, leaves, and berries, sometimes cooking them after he learns (by accident) fire. He wants to be liked and loved but his horrendous form—eight feet tall and made from inanimate matter brought to life—draws only terror, rebuke, revulsion, and violence from everyone around him. He pays the world back in kind, at first killing a child then turning his attention to Victor Frankenstein’s family. Frankenstein pursues the monster to the North Pole but dies and the monster drifts off on an ice flow, promising to immolate himself. By Aristotle’s theory, the fable must be a tragedy, a story about a being brought down by circumstances not of his own choice but of his own making. 

Rayguns over Texas was published in 2013 by FACT the Fandom Association of Central Texas. It contains 19 short stories and eight essays. I bought my copy at my first ArmadilloCon (39) in 2017. The book disappeared into storage boxes when we moved from Austin to Kyle. Looking for something else, I found it and I now know some of these authors. So, I started with those stories. 

“Texas Died for Somebody’s Sins But Not Mine” by Stina Leicht is another Frankenstein story. This retelling has been informed by decades of science fiction and political theory. This monster is a transgenetic clone labelled “Dallas” and called “Una” who works as a computer programmer and is the legal property of a corporation. She is harmless and truly a victim. She escapes the software factory for one night of selfish pleasure. When she slips back in, she learns that she had been discovered. It does not matter on two grounds: this project is closing, so she was going be erased and reprogrammed with different skills anyway; and against that she knows that she had her own life for a short time, even though she will not remember any of it. 

I believe that “Operators are Standing By” by Rhonda Eudaly is a personal story told through aliens. Set in a galactic sales call center, it is about belonging. If you saw Boiler Room or Wall Street, you get the picture. Moreover, Fahrenheit 451’s Montag would say that this is autobiographical and is on a narrative level forbidden in his society. 

Of these first three stories, I found "Jump the Black" by Marshall Ryan Maresca to be the most emotionally engaged. The viewpoint character is an illegal alien, a Terran seeking to get off the Deathplanet which we turned Earth into. Imagine a world of homeless people, living on whatever is left of the streets, paying smugglers to get them anyplace else. Many die along the way. That’s how it is. Keep moving. 

After I finished the three-part review of ArmadilloCon 47 last month, I left messages in the contact pages of the websites of the vendors, authors, and fans whom I mentioned. Panelist Lauren Teffeau replied with corrections to my blog post. Reading her website, I discovered the Solar Punk subgenre in which home-brew solutions remediate some of the environmental sins of our time. From the libraries at the University of Texas (Austin), the City of Austin, and the City of Kyle, the closest I could come was Bike Topia: Feminist Bicycle Science Fiction in Extreme Futures, volume 4 of the Bikes in Space series from Microcosm Publishing. 

The narrative style of “Riding in Place” by Sarena Ulibarri is matter-of-fact, unadorned writing. So, I just followed the story and I did not foresee the (surprise) conclusion. It is another smuggled alien story told from an outside viewpoint as we follow our human corporate worker on an industrial space station orbiting Earth. I was reminded of Bruce Sterling’s Islands in the Net which opens with a middle class corporate office work gang ripping up old telecom lines and patching the landscape.They do the job they are given but they don’t have much enthusiasm for it: “it’s community work,” they say. In Sarena Ulibarri’s utopia of megacity biking trails and parkways, everybody gets assigned some tough jobs and working on the space station is one of them. Hence the bicycles to maintain bone strength. 

Maddy Spencer’s "Meet Cute" is a graphic flash story with neither narration nor dialog. The pictures tell the story. Montag would have read this before he discovered books. 

"Portlandtown" by editor Elly Blue weaves the threads of self-discovery within a tapestry of complex future sociology told as history. 

The stories in BikeTopia are fresh. The plots are the ones we know from The Bible and The Iliad and Shakespeare. The tellings are new and now.

The Roots of Language

I call the inflection point in human history when thinkers gave structure to the words in their heads the Grammatical Revolution. 

We easily find the roots of science fiction in mythology because we commonly accept that people - perhaps protohumans - told wondrous tales around the campfire. However, that may not be so. The IndoEuropean languages are no more than eight thousand years old, and perhaps only half that. Estimates for the oldest possible forms of Chinese (protoSinitic) are perhaps half again as old as protoIndoEuropean. It may be easy to accept that the purpose of language is communication with other people because human language evolved from animal calls. Ravens and crows are notorious talkers with large vocabularies, including gestures. However, that is not the primary purpose of language. 

The primary purpose of language is to enable thinking. Thinking is private. Alone on an island, you would have no one to talk to. Your survival would depend on the contents of your mind. 

https://en.wikipedia.org/wiki/Lithuanian_grammar
It has been said (not in Wikipedia) that Lithuanian has retained
more proto-IndoEuropean forms than other IE languages.

And there had to be a "first thinker." I believe that rather than solitary they were a pair of females who invented their own grammar to deliver nuance to their speech. Then they taught it to their children, preferentially to their daughters. Succeeding generations added complex rules in order to better explain their sensory perceptions and mental conceptions. "I see them take your new food to her yonder fire." 

Counting only 1-2-Many, the PIE Caucasians all borrowed their word for "seven" from their Semitic neighbors.
