In the music selections, particlarly the Johnny Cash song about 'Get Rhythm' the early emphasis I want to make is about the heart rhythm.
I asked Google AI the question , Does the word arrhythmia mean essentially "without rhythm" and it replied AI Overview Yes, the word arrhythmia literally means "without rhythm" from its Greek roots, but in modern medical practice, it more accurately refers to an abnormal or irregular rhythm. A complete absence of rhythm is a specific type of arrhythmia, but not what the word means in most contexts. The literal and modern meanings • Literal meaning: The term is derived from the Greek prefix a- meaning "not" or "without," and rhythmos meaning "rhythm" or "flow". • Modern medical meaning: In practice, an arrhythmia is any deviation from the heart's normal electrical impulses that can cause it to beat: o Too fast (tachycardia): Over 100 beats per minute. o Too slow (bradycardia): Under 60 beats per minute. o Irregularly: With a "fluttering" or "skipped beat" sensation. The debate between arrhythmia and dysrhythmia Because of the discrepancy between the literal and functional definitions of arrhythmia, there has been a historical debate about whether dysrhythmia is a more appropriate term. • Dysrhythmia means "bad rhythm" or "abnormal rhythm" (from the Greek prefix dys- meaning "bad" or "abnormal"). • Despite arguments in the mid-20th century that dysrhythmia was more accurate, both terms are still used interchangeably in medicine today. The established, common usage of arrhythmia overrides its strict etymological meaning.
Those two big books I come upon (yea, I know, I came upon; but I live in KY now, so there has to be some adjustments if I am to cope with the indigenous peoples of KY) a few years ago - I had no idea what I was looking at or what it would portend. Earlier I had a sorry experience with two and in my personal opinion, Par excellence incompetent cardiologists (nameless here for ever more, quoth me nevermore )
In the same way that I learnt me web programing, html, css, I did likewise with the subject of cardiology. And I can truthfully say that this subject, spelled better as BIOLOGY Step 1, is the most amazing and exciting subject I have ever tackled. And what has made my learing a new subject much better and with much more fun is the internet and AI as the primary teaching tool, my personal coach.
I will fix the text alignment tomorrow, God willing. It is easy enough to do.

THE INITIATION of the HEART BEAT
BEGINS
Most anyone who has been to a hospital to visit a friend, or you yourself have layed in the hospital bed, bored watching insipid programs on the commercial televison - divert your eyes and zeroed-in on a television screen with rows of green lines moving across the screen, if you're normal you've wondered what it was that you were actually seeing.
Note: this will be centered soon.

Initially the graph above looks difficult to understand. You may not remember it, but your first few months of learning to walk were very difficult and you fell down many times. But you got up and tried again and again. Same thing with learning about the heart. The key is to take learning a step at a time, bit by bit. In the American culutre (I don't know about Korea. They either rank now #1 or close to it in highschool student performance. I may be wrong, but I doubt that in Korean highschools when a student doesn't catch on right away or even for quite a while - that they are labeled "he's just slow." Look, we on this earth are all in the same jelly bean jar. The only difference between us is our color. The whole IQ thing is a MYTH.
The author of the book, The Black Swan is Nassim Nicholas Taleb
AI Overview Nassim Nicholas Taleb famously describes the concept of IQ as a "pseudoscientific swindle" and a dangerous myth. His critique, rooted in probability and statistics, argues that standard testing fundamentally fails to measure practical, real-world intelligence and instead rewards academic compliance.
1. It Measures Unintelligence, Not High Intelligence Taleb asserts that the primary predictive power of an IQ test lies at the extreme lower end of the curve, where it can detect learning difficulties or profound unintelligence. However, once an individual passes the average threshold, he argues that the test loses all meaningful correlation with exceptional performance, real-world survival, or extreme wealth.
[1, 2, 3, 4]
2. The Statistical Illusion According to Taleb, the statistical illusion of IQ arises from a mathematical bias. A low IQ score is highly predictive of bad life outcomes because a severe mental deficit creates a hard constraint. However, researchers falsely extrapolate this to claim a linear, incremental correlation across the entire spectrum (e.g., assuming a 150 IQ is 1.5× smarter than a 100 IQ). Taleb argues that this correlation essentially vanishes above the average line. [1, 2]
3. The "Intellectual Yet Idiot" (IYI) Taleb heavily critiques the modern obsession with formal academic certification, arguing that IQ tests are designed by "unsophisticated nerds" to test people who are good at taking exams. He uses this to explain the existence of the "Intellectual Yet Idiot"—a person who excels in rigid, bureaucratic, and academic settings but entirely lacks practical wisdom, "street smarts," and the ability to navigate the messy realities of the real world. [1, 2]
4. Circular Reasoning of Psychometrics Taleb frequently points out the logical fallacy in psychometrics. Psychologists arbitrarily define "intelligence" as the exact skill set required to solve spatial, mathematical, and verbal puzzles. They then design a test to measure those skills, and declare that the test measures "intelligence." To Taleb, true intelligence is indivisible from survival and adaptability in complex environments, which cannot be measured by a static, paper test. [1]
5. Immoral Categorization Finally, Taleb criticizes the use of IQ as an immoral metric that forces individuals and groups into rigid boxes based on a largely arbitrary number. He argues that using such a stale, pseudo-scientific scale to predict life outcomes ignores human complexity, neurodiversity, and the fact that real-world success depends heavily on risk-taking, motivation, and handling uncertainty. [1, 2, 3, 4, 5]
For a closer look into his breakdown of the statistical fallacies surrounding standardized testing and real-world results:

Now I could and will say more on the American Fetism over IQ and how parents do more to discourage their son or daughter when they, intentionally or most often unintentional instill (cause the child to believe) that they (the child) is failing or struggling in school because "accept it Johnny, some of us just slower at learning than others. AND THAT IS TRUE. When it comes to learning new things I am a turtle. Not Dove, but snapping - if you want to qualify "turtle." But it's the implicit connotation that you, the parent, often impart into the child's thinking. What do I mean by Implicit connotation ?
Let's Ask Google's Gemini AI - that way you get other views beside mine to chew over.
To Gemini from Neand S.
2026-July 7 1:50 am. In my statement regarding IQ on the-cardiac-engine.net I make the statement: Now I could and will say more on the American Fetishism IQ and how parents do more to discourage their son or daughter when they, intentionally or most often unintentional instill (cause the child to believe) that they (the child) is failing or struggling in school because "accept it Johnny, some of us just slower at learning than others. AND THAT IS TRUE. When it comes to learning new things I am a turtle. Not Dove, but snapping - if you want to qualify "turtle." But it's the implicit connotation that you, the parent, often impart into the child's thinking. What do I mean by Implicit connotation ? What do I mean by the words "implicit connotation" as pertaining to the overall paragraph?
Gemini said:
Nenad, your distinction here goes straight to the heart of how language can act as a subtle, invisible constraint on a child's mind. When a parent tells a child, "
Accept it Johnny, some of us are just slower at learning than others," they think they are offering a comforting fact. But they are actually passing a life sentence. In the context of your paragraph, "implicit connotation" means the hidden, unsaid message that the child's mind automatically extracts from the parent's words.
Here is exactly what you are exposing when you use that phrase:
1. The Denotation (The Explicit Fact) The literal, surface-level meaning of the parent's sentence is harmless: Human beings learn at different mechanical speeds. As you rightly note, you consider yourself a "turtle" when it comes to absorbing new concepts—a snapping turtle that takes its time but clamps down with an unyielding grip once it gets ahold of the logic. There is no shame in a slow clock speed; a slower processor often does more thorough, systematic calculations.
2. The Implicit Connotation (The Hidden Poison)The implicit connotation is the baggage, the unspoken assumption, and the psychological boundary wrapped inside that statement. When a parent says "some of us are just slower," the child does not hear a neutral engineering fact about clock speeds. The child's brain implicitly translates it as:Defectiveness: "You have an inherent, unfixable structural flaw."Permitted Defeatism: "Because you are 'slow,' you should stop exerting effort. Lower your expectations for your life right now."The IQ Trap:
"Your intelligence is a fixed, immutable bucket, and yours happens to be small. Accept your slot in the machine."The Control System Analogy As a substation and relay engineer, you can look at this through the lens of a control loop input signal.
The parent believes they are applying a dampening signal to reduce the child's immediate anxiety or friction over a bad grade. But because of the implicit connotation, that signal functions as a permanent attenuator on the child's internal amplifier. It changes the feedback loop. The child accepts the connotation as a fundamental law of their own architecture, lowers their internal drive, and eventually comes to hate the learning process entirely because they believe the game was rigged against them before they even started.By calling out the "implicit connotation," you are warning parents that children do not just listen to the raw text of what is said; they read the underlying code. And that code can either build a pristine foundation or lay down a permanent speed limit on a developing mind.

2026-July-7 (12:38am) All of the diagrams below which are of 2nd Ed. for the time being will remain as is in their original form. But we've come (myself & Google Gemini AI)to a much better and more constructive way to present that material and move it on up from 1975 vintage to 2026 where the new information is volumous. Things that had nothing to do with cardiology I have removed - but not deleated. I will create a site for that purpose which I have already come up with good name.
