Write4U's wobbly world of word salad woo

I didnt mention functions
I used the term to illustrate how the mathematics of a function are actually expressed in a physical way.

Take the "exponential function"
In human symbolism this fuction is expressed as a graph which is an abstract data type that does not exist in nature.

But in nature this mathematical function results in the measurable and predictable doubling rate of say, a bacterial population.

Actual numerical doubling of population at 20 minute intervals.

This seriously underestimated natural mathematical function is what Professor Albert Bartlett warned the general public about.
The world had a recent experience with this mathematical function during the COVID pandemic.

An amusing story

I first heard this tale as an undergraduate in an analysis class. The first half of the story, with an appropriate ending, is suitable for students who are having difficulty understanding exponential growth. The entire story reminds beginning analysis students that sequences—actually, series—do not behave as we might imagine.

The real world result of this simple abstract mathematical function is not a product of human imagination.
This is not "why this mathematical formula works", but "how it works".

I know what a function is.

LOL. I know you do. You are not the "general public".

But there are some who don't believe I do...o_O

But more important is the recent proposal that the universe evolves "for function", as well as "for complexity" (Robert Hazen)

You don’t.
 
You don’t.
Well, I understand that the moon's orbit around the Earth is a function of time, and oddly is an abstract mathematical function.
I also know that it is not mathematically perfect, but that is due to other environmental influences, but it always "attempts" to follow the mathematical guiding principle of a perfecr circular orbital movement.
It's the physical influences that won't allow a mathematically perfect circular orbit.

Doesn't Kepler's Law of orbital motion explain the mathematics involved? In any case, an ellipse itself is not a physical but a mathematical object, no?

Forget about real world analogues, mathematics is abstract and if you have to cite something real to illustrate it then you are immediately losing the central points.
Functions are about variables (dependant and independent) constants, sets, domains and maps.

If buy a book on Calculus the first chapter should tackle functions, if you do not understand that, you will not understand calculus.

The reason Exchemist is skeptical regarding your understanding is your use of the world "function" possibly.
Mathematics is about pedantry, specifics and rigor, every symbol, number, word means something very specific.
One cannot throw in the word value, function, differential into a sentence w.r.t. mathematics without proper application.

I think I mentioned this before, once or twice.

..thus illustrating that, indeed, you have no idea what a function is.

As I told you a few days ago, if you persist in trying to outsource your thinking to internet links, all you do is draw attention to your failure to actually understand the subject matter. If you want to show you understand what a function (or indeed any other concept) is, you need to be able to explain it in your own words.

You have been told over and over again, over a period of several years now, by several people, what a function is, to the extent that it has become something of a running joke on the forum. But nothing seems to penetrate your thick skull.

And where did you get your knowledge from. Did you make it up or learned it elsewhere.

Tell me what is wrong with this piece of information about "function", because this is what I understand a (mathematical) function to be.
function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable). Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences. The modern definition of function was first given in 1837 by the German mathematician Peter Dirichlet:

  • A function is a relation between a set of inputs and a set of possible outputs, with each input linked to exactly one output.
  • This relationship is often denoted as f(x), representing the function applied to an input x.
  • For example, f(x) = x^2 means that an input of 4 results in an output of 16.
  • Functions are vital for describing mathematical relationships and can be depicted through equations, graphs, and sets of ordered pairs.

That is not the point. I had no idea what an amino acid was till my teacher told me.
The issue, which has been outlined, is your use of references.

If you had a family holiday, you would not send me your niece's Facebook blog of the event, you would tell me.

Use your images and your recollections.

Otherwise everything is second hand, involves little about you and in this case where technical details are involved, difficult to know whether you grasp a concept.
 
And where did you get your knowledge from. Did you make it up or learned it elsewhere.

I don't believe you.

You will be relaxing after dinner next month and decide to browse SF. You see a comment regarding, "self organising relational values."

Do you:

Have an after dinner mint and pick up a magazine.
Put the entire catalogue of Bach two part inventions on the record player and relax with a single malt.
Decide that it's time we claimed the US back as part of the Empire and write a letter to Starmer.

Or admit to yourself these are just rage coping mechanisms?

I am not wasting any more time discussing the meaning of “function” with Write4U. It’s been done to death, with no effect.

I may interject to tell him he’s wrong about something, though. There are always opportunities to do that.:biggrin:
 
Has anyone ever made the connection between medical tests such as phlebotomy and as imitating what the various parts of the brain does naturally? I find that most remarkable!

The brain has multiple functions, including12345:
  • Receiving, processing, and interpreting information
  • Storing memories
  • Controlling movements
  • Regulating blood pressure and breathing
  • Releasing hormones

What Is Phlebotomy?​

Phlebotomy is when someone uses a needle to take blood from a vein, usually in your arm. Also called a blood draw or venipuncture, it’s an important tool for diagnosing many medical conditions.

Usually the blood is sent to a laboratory for testing.

To think that under normal cicumstances the brain does all that testing and keeps the body's homeostasis balanced for optimum performance.
It boggles the mind. As I understand it Homeostasis is a subconscious mathematical function of the brain.

Are you going to respond to my posts, numbers #427 and #428 or not?

It looks to me like you're shutting your eyes and running away from them as fast as you can go.
 
Does the number 3 determine that an atom is a lithium atom? No! No more than the number 3 determines that a jar is a lithium jar.
What a ridiculous false equivalence. Do you really think I am that stupid?

The number of protons always determines the type of atom. It's called the "atomic number"

Atomic Number
The number of protons in the nucleus of an atom is its atomic number (Z ). This is the defining trait of an element: Its value determines the identity of the atom. For example, any atom that contains six protons is the element carbon and has the atomic number 6, regardless of how many neutrons or electrons it may have.
Happy now?
 
Gravity keeps it there. Importantly: maths doesn't keep it there.
Yes it does It is the value (strength) of the gravity that either keeps it there or not.

I think this particular claim of Tegmark's (which I think he wisely refers to as a hypothesis) is silly, too - for all the same reasons.
Perhaps you do not fully understand the depth of the claim.

You've been glued on to certain propositions for a few years now, at least. I don't see much exploring going on. In fact, you seem to be highly antipathic to learning anything new.
Perhaps it is you who is loath to learn something new.

Does "triangulation" not apply to free throws?
Of course but that is not what I said. You made that up.

Do you think they unconsciously make mental calculations, then? (Because I don't think that's what's going on, either.)
Yep, the brain has prepared tself to execute that mathematical function instantaneously, just as a chameleon is not conscious of it use of triangulation.

Do you think I'm in error, and not you? If you do, then why haven't you shown where I'm wrong, on any of the three previous times where I explained where you are wrong?
I have but you reject it every time for apparently the same reason, which you never support with an example, unless it is something like your ridiculous example of the number of jellybeans in a jar determinig the type of jar. Jeez.....

I am trying to lead you down a path that shows that the implications of your assertions are absurd.
Please don't use absurd examples to prove your point.

Tell me what I've got wrong about your meaning. Be specific.
It seems that you reject the fact that humans have recognized the underlying mathematical logic in physics.
Naturally occurring mathematics are discovered, the human symbolic representation of the mathematics is invented.
But human maths actually prove the validity of the mathematical concept. They work in their own right, both theoretically and practically.

Stereopsis is not triangulation, according to the definitions you have posted.
Stereopsis is the computation of depth information from views acquired simultaneously from different points in space. For many years, stereopsis was thought to be confined to primates and other mammals with front-facing eyes. However, stereopsis has now been demonstrated in many other animals, including lateral-eyed prey mammals, birds, amphibians and invertebrates.
1736673057286.png

All sighted animals face the problem of how to derive information about a 3D world from 2D retinal images. 2D images contain a range of depth cues which can, in principle, be used to derive information about 3D structure. Depth cues can usefully be grouped into three classes (Banks et al., 2016): light transport (e.g. shading), perspective (e.g. looming; see Glossary) and triangulation (e.g. stereopsis; Fig. 1). Triangulation depth cues are based on comparing views of an object from multiple locations. This is a particularly reliable means of depth perception because it depends only on geometry, rather than on assumptions about the specific scene.

No!
You just did it again. You jumped straight from "good physical reasons" to mathematical reasons. But mathematical reasons are all conceptual, and concepts can't cause physical results.
Good physical reason (efficiency) resulting from the mathematically efficiency of the "pattern". This is what "natural selection" does!

Are you even aware of the difference between "physical reasons" and "mathematical reasons"?
I believe I do. But the question can be asked from you as well.

Abstract​

"Universal Pattern Beyond Reality: Exploring AI, Euler, Cosmos, & Human Behavior" examines the profound connections between mathematics, artificial intelligence (AI), the cosmos, and human behavior. At the heart of this article is the idea that the universe operates through universal patterns of growth, decay, and transformation, which are mathematically governed by constants like Euler’s number (e = 2.718).
These patterns are not only observable in the physical realm, but they also extend to the functioning of the human mind and behavior, offering a holistic view of how everything—from cosmic structures to human thoughts—follows a cycle of evolution. (via natural selection)
bracketed mine.
Key Themes of the Article: Euler’s Number and Universal Patterns: The article explores how Euler's number (e), a mathematical constant representing exponential growth and decay, underpins many processes in the universe.
It serves as a model for understanding the natural cycles in everything from the formation of stars to the development of ideas and human consciousness. The concept of exponential growth and decay is applied to both physical systems (such as galaxies, atoms, and energy) and abstract systems like human thoughts, emotions, and decisions. This shows how the universe is governed by continuous processes of transformation.

Do you now agree that you were wrong about that?
Read what I wrote!

After all, exchemist - whom I don't think would be insulted to be referred to as a member of the skeptical science community - told you that the "new proposal" doesn't contradict any mainstream concept of entropy
Then what are we arguing about?

Knock me down with a feather! Did you really write that? After all that? If numbers don't exist except in the minds of humans, how could they possibly determine what kind of element an atom is?
Because "numbers" are human invented symbols for naturally odccurring "values". The numbers do not exist in the universe, but the corresponding values do!

Clearly that's impossible if "values" are numbers and you don't believe that numbers exist except in the minds of humans. "values" represent much more than "quantity", they also represent "quality." Look deeper!

A rock can't have an inherent value as you assert it does, because the rock exists independently of the mind of a human.
You're contradicting yourself. That means your entire edifice falls in a self-contradictory heap.
Here we go again with the false equivalence. Rocks have very defined values that can be symbolized with human numbers.

Hint: you can't make a jelly bean from the number 3.
We agree, but it is an irrelevant observation.

Phlebotomy is not a medical test. It is the procedure of drawing a blood sample.

Yes, that was sloppy. But phlebotomy is usually performed for purpose of testing, no?
That was the point. The brain is constantly evaluating the quantity and quality of the blood supply .

Yes, the brain - and numerous other regulatory systems in the body - do lots of jolly complicated things. Thank you, Einstein. :rolleyes:
