A JWL Mini-Lecture: Introducing A New BASE CALCULUS: Theory & Applications of Arbitrary Symbol Sets

https://youtu.be/Q14rhTaFlXs?

πŸ‘†πŸΌπŸ”† Delivered on 28 April, 2025, this Mini-Lecture, a continuation of Internet Community Blackboard Adventures by Fut. Prof. JWL, briefly presents an interesting application of the recently furthered theory concerning symbol sets and the GTNC. Essentially, we get to see how, even for arbitrary or rather esoteric number systems such as numbers that use neither the Latin Number System nor the more typical Arabic Number System, we still can treat of such strange numbers using the GTNC mechanics, logic and notation, to quantify their properties, analyze them and more.

It is recommended to read JWL's recent paper so as to properly make sense of what's going on here: https://bit.ly/ossipaper

FIRST QUEER CONSEQUENCES OF THE lu-BASE CALCULUS

-Γ—--------Γ—-Γ—--------Γ—-Γ—--------Γ—-Γ—--------Γ—-Γ—-

Talking of the first consequences of the new Lu Base Calculus --- summing we refer to the proposed body of base-algebra and symbol set logic[2] from Joseph Willrich Lutalo as such.

We find that by first taking a leap of faith and closing our eyes to what magnitudes we normally assign common symbols or digits in the typically, conventional Arabic Number symbol set for base-10 (the digits 0-9), instead, using the meaningful Base Calculus idea of determining a digit's value or cardinal magnitude based on its position within the ordered symbol set of the base to which it belongs[1] (meaning, assuming we were to redefine the base-10 symbol set with its usual digits ordered differently not as they conventionally are), we essentially would have to rethink the meaning not just of individual digits, but any multi-digit number such as 894! This new mathematics might surely end up disrupting all conventional mathematics and science! And there might be a need to rewrite the foundational philosophy of most mathematics.

Yup yup πŸ€­πŸ˜† I'm telling you... Base Calculus is so crazy!! We must rethink numbers starting now πŸ™ˆ #basecalculus #modernmaths #symbolsets just madness!!!
And then, think, if you might, what happens if, instead of attempting to visualize such NE or number sequences as the interesting n-SSI & o-SSIs using the calculator keypad method (a 3Γ—3 matrix), we instead use a traditional numberline (also, because, some calculators and computers do have their numerical pads as a linear sequence of digits instead of a matrix). Compare this way of visually analyzing the o-SSIs to the method of the matrix shown in the original o-SSI paper. Do you see any interesting or exciting patterns yet?*

Such a well spent day... Mostly studying an entertaining advanced CS paper: Bikos, Anastasios, Panagiotis E. Nastou, Georgios Petroudis, and Yannis C. Stamatiou. "Random number generators: Principles and applications." Cryptography 7, no. 4 (2023): 54. h…
Not yet finished reading that very epic paper on RNGs (Anastasios Bikos et al, 2023). Currently done with reviewing it up to just page 4 (out of 30!). Did look up some of the referenced works too.. especially the NIST paper on RBGs (2018). I trust, we are making progress, and the Holy Grail is starting to appear near the horizon!

Meanwhile, talking of making progress with mathematical research.. Lately I have made a habit of waking up to test myself on important Mathematical Facts.

Of course, my current focus is on preparing for that RNG paper and the theory I'm steadily building from scratch... It concerns numbers, and not just any numbers! 🀭

So, I'm currently in bed with some (now 5) important mathematical and natural constants, and can write those numbers down even if you wake me up in thee middle of the night!!

## MOMENTS With ARCH L | Hip Hop Lesson: RAP & Produce BEATS too!

[V] https://youtube.com/shorts/Ub-Hw_ikIOk

In a brief interaction with Ugandan Underground Hip Hop Emcee, ARCH L, we get some tips from him concerning how to really get deep into Underground Hip Hop (lesson to young ones especially); Learn Hip Hop; listen to the music, keep records in sound and in writing; learn to rap or rather how to emcee, but also learn how to produce or make your own original Hip Hop beats βš‘πŸ”±πŸŽ™οΈ

Talking of which, the beat used in this brief educational video was the first of its kind that I ever made on-the-fly and purely just using the mobile phone even though it might sound cool and perhaps too professional for some newcomers!

I had first attempted to upload the video with an already made Hip Hop instrumental ("Dreams" by The Game) that I had downloaded from the Internet previously --- many video creators on the modern Internet via TikTok, WhatsApp, YouTube and other playoffs platforms generally do this; they record their own video or voices, and then just mix them with someone else's beat, especially because it's simpler to do and many internet softwares and apps encourage or support it.

But, upon uploading the first video to YouTube, it was flagged as having copyrighted material and was tagged as "invisible worldwide" -- meaning people wouldn't be allowed to view it. I was advised to re-upload without the Copyrighted soundtrack or none at all. At that moment, panicking as I didn't want to waste time and didn't want to go make a beat via the desktop PC (from where I normally make such Hip Hop tracks from say Fruity Loops Studio software),

I decided to consult my Copilot Artificial Personal Assistant for simple apps useful in producing hip hop beats via the phone. Among software it recommended was an app called "BandLab". I downloaded it and immediately started trying to make a beat with it. I was low on data, and so couldn't use it properly in offline mode; for example, couldn't just download preset instruments, beat loops or pads for use in composing an original instrumental quickly/simply, and so, after noticing it had the option to allow turning "any" sound sample into an instrument, I then decided to create some original sounds of mine using ordinary stuff lying around... hitting metal objects to produce snares, throwing pieces of glass against each other to make interesting effects and rubbing my hand over some rough surfaces... (not use of real drums or musical instruments even though I had them back in the house). So, all these I recorded using normal phone microphone and the phone's sound recording tool.

There after, I tried to import those improvised sounds into the BandLab Software so I can make the beat. But, being a first time user of the tool, I noticed progress was very slow and there was still much to learn yet I had little time, and so, having noticed/quickly recalled the basic ideas behind such beat-making;

- envision a kind of soundtrack you wish to make and especially how its drums shall sound like --- the "rythm" of the beat. For Hip Hop, that typically means a 4-4 or 4/4 pattern, but others might also use the "Amen-break" pattern that's slightly faster. Essentially, you have a leading drum hit, some responding snares and/ot hi-hats or cymbals and then a background sound or perhaps a pad to support these, and then merely looping these, with some few variations of these later-on, to make the beat not so monotonous across its entirety).

- use available things (kitchen implements, pieces of rocks, your hands, mouth sounds, background noises, live music instruments, etc) to record short sound clips that shall serve as the starting materials to make important components of the beat.
