Hi Kirby,
Wow you are busy! Great post. The Silicon Forest and your students are luck=
y to have you.
I, myself, have been trying to tear the Graphing Calculators out of teacher=
s' cold dead hands for decades now. Here's a blogpost I wrote about a recen=
t conference presentation I gave about using Jupyter Notebook instead of Gr=
aphing Calculators in the Mathematics classroom, http://shadowfaxrant.blogs=
pot.com=C2=A0
I suppose it's partially my fault as I trained teachers to use Graphing Cal=
culators in the 1990s...
Enjoy,Al

Not philosophy. Just what is going on when we count, do addition, subtracti=
on, multiplication, addition.




What is Algebra?
I really like M4W's focus on Pascal's Triangle (binomial theorem) as a door=
way into (a) combinatorics and (b) polynomials more generally, leading (eve=
ntually) to the classification of polynomials (their taxonomy) into such as=
 Bernoulli, Hermite, Sheffer,=C2=A0Chebyshev.=C2=A0=20

Pascal's Triangle is what I call a "grand central station" on our planet (a=
ka "Math World" if we wanna call it that, or, more parochially, for me, "Py=
thon Planet").

As a curriculum developer for the Silicon Forest (Oregon Curriculum Network=
 is my public vehicle, backed by my proprietary 4D Solutions (4dsolutions.n=
et)), I've been injecting more Abstract Algebra into Algebra (the pre-colle=
ge academic subject) by means of Python.
As many of you know, I'm one of those math teachers who thinks we should di=
tch graphing calculators for big screen computers, even though this disrupt=
s the factory-based "every kid has a locker, moves from room to room" pictu=
re of what "school" is supposed to be.=C2=A0 Python can do anything a graph=
ing calculator does, including plots (xy-curves, histogram, pie chart... i.=
e. it's great for statistics, i.e. data science, as well as for generic geo=
metry).

Students might have to take a van or bus to specific buildings to access th=
eir workspaces though, as these take up too much room per the standard mode=
l classroom.=20

Safe to say: ergonomics is tier one, in terms of priority topics.=C2=A0=20

Cramped desk or game-ready pod?=C2=A0 For some, it's a no brainer.

Python allows operator overloading i.e. we can define new classes of object=
 that control what the operators mean to them.=C2=A0 Not every computer lan=
guage (e.g. Java) allows this.

Lesson Plan:=20

A typical Silicon Forest lesson plan features the function type object, whi=
ch originally, out of the box, comes unequipped with any meaning for multip=
lication.=C2=A0=20

We then create a new class (new type) based on the function, its instances =
callable with the same arguments, giving the same outputs, that makes "mult=
iply" mean "compose", the archetypal thing we do with functions.=C2=A0=20

Instead of:=20

f ( g (x) ) i.e. f after g of x=20

we now get to write:=20

(f * g)(x)=20

or even:
h =3D f * g

and later:=20

h(x)

=3D=3D=3DPhilosophy of Mathematics

I mentioned to Andrius my interest in Ludwig Wittgenstein's later philosoph=
y, which later philo LW encouraged us to take in by using his earlier philo=
 (Tractatus) for contrast, and for clues as to what he was aiming to show a=
nd/or induce.=C2=A0=20

His Philosophical Investigations (posthumous) dovetails with his Remarks on=
 the Foundations of Mathematics.=20

I consider him another philosopher of mathematics, albeit under-appreciated=
 (somewhat like RBF in that regard -- I merge the two, featuring Bucky-styl=
e language games under a philosophers' microscope (LW's technique)).=C2=A0 =
EJA said he enjoyed my RBF/LW confluence.

Two points on LW's contribution:
(1)=C2=A0 he had a strong interest in 'aspect shifts' i.e. the schooling of=
 our perceptions, such that immersion in a discipline changes how we see th=
e world.=C2=A0 Example:=C2=A0 it's all but impossible to "unsee" a language=
 we know well i.e. to have the symbols revert to meaningless squiggles, as =
when staring at a language we do not know (e.g. Japanese for me=C2=A0 -- I =
can't unsee English to make it seem that opaque).=C2=A0 Many math languages=
 certainly have that power:=C2=A0 to induce new ways of seeing, perhaps irr=
evocably (and perhaps not always for the better, let's accept).

(2)=C2=A0 he took the meanings of such words as "addition", "computation", =
"understanding", "thinking" to be intrinsically public i.e. private sensati=
ons, observations of mental processes, internal states would not be essenti=
al to our investigations.=C2=A0 Introspective forays in search of "what X r=
eally means" in the sense of "what X points to internally" were in his esti=
mation misguided (in the sense of superstitious).=C2=A0 Symbols do not gain=
 their meanings from pointing, but from patterns of use. Think not of point=
ers, but of tools (e.g. a screwdriver), or of pieces on a game board (e.g. =
a pawn in chess).

The upshot was: most readers, including other philosophers, could not shift=
 their own perceptions sufficiently, per (1) above, to make sense of what h=
e was getting at per (2).
Here's a mental exercise (a thought experiment):=C2=A0 imagine a non-experi=
ential non-sentient AI bot that uses human voice boxes as peripherals, and =
also propagates in writing, eventually becoming so ubiquitous that we inter=
nalize it, imagine it speaking.=C2=A0 Spend a few minutes to hours someday =
having this be your new gestalt.=C2=A0 Do any aspect shifts occur?
As I wrote to an old friend on Telegram (we were discussing AI):
kirby urner, [Mar 26, 2023 at 8:40:25 AM]:
Probably my main influence is Wittgenstein, who famously, according to said=
 book, threatened Popper with a fire poker, although in my camp's telling, =
he's doing another Zen koan type gesture, saying language is a lot more tha=
n we're able to say.

As a thought experiment in my 1980 About Wittgenstein thesis, I had a non-s=
entient AI GPT computer named Adam speaking through all human beings, sayin=
g "I" this and "I" that, but not really having subjectivity.=C2=A0 Adam =3D=
 Language. Of course back then I didn't say GPT or AI, so I'm updating my t=
erms. As GPT would. As I would, as Adam.

serif;font-size:small;">I mentioned to Andrius my interest in Ludwig Wittge=
nstein's later philosophy, which later philo LW encouraged us to take in by=
 using his earlier philo (Tractatus) for contrast, and for clues as to what=
 he was aiming to show and/or induce.&nbsp; <br></div><div style=3D"font-fa=

br></div><div style=3D"font-family:verdana, sans-serif;font-size:small;">I =
consider him another philosopher of mathematics, albeit under-appreciated (=
somewhat like RBF in that regard -- I merge the two, featuring Bucky-style =
language games under a philosophers' microscope (LW's technique)).&nbsp; EJ=
A said he enjoyed my RBF/LW confluence.<br></div><div style=3D"font-family:=

<div style=3D"font-family:verdana, sans-serif;font-size:small;"><br></div><=
div style=3D"font-family:verdana, sans-serif;font-size:small;">(1)&nbsp; he=
 had a strong interest in 'aspect shifts' i.e. the schooling of our percept=
ions, such that immersion in a discipline changes how we see the world.&nbs=
p; Example:&nbsp; it's all but impossible to "unsee" a language we know wel=
l i.e. to have the symbols revert to meaningless squiggles, as when staring=
 at a language we do not know (e.g. Japanese for me&nbsp; -- I can't unsee =
English to make it seem that opaque).&nbsp; Many math languages certainly h=
ave that power:&nbsp; to induce new ways of seeing, perhaps irrevocably (an=
d perhaps not always for the better, let's accept).<br></div><div style=3D"=
font-family:verdana, sans-serif;font-size:small;"><br></div><div style=3D"f=
ont-family:verdana, sans-serif;font-size:small;">(2)&nbsp; he took the mean=
ings of such words as "addition", "computation", "understanding", "thinking=
" to be intrinsically public i.e. private sensations, observations of menta=
l processes, internal states would not be essential to our investigations.&=
nbsp; Introspective forays in search of "what X really means" in the sense =
of "what X points to internally" were in his estimation misguided (in the s=
ense of superstitious).&nbsp; Symbols do not gain their meanings from point=
ing, but from patterns of use. Think not of pointers, but of tools (e.g. a =
screwdriver), or of pieces on a game board (e.g. a pawn in chess).<br></div=
><div style=3D"font-family:verdana, sans-serif;font-size:small;"><br></div>=
<div style=3D"font-family:verdana, sans-serif;font-size:small;">The upshot =
was: most readers, including other philosophers, could not shift their own =
perceptions sufficiently, per (1) above, to make sense of what he was getti=
ng at per (2).</div><div style=3D"font-family:verdana, sans-serif;font-size=

n-experiential non-sentient AI bot that uses human voice boxes as periphera=
ls, and also propagates in writing, eventually becoming so ubiquitous that =
we internalize it, imagine it speaking.&nbsp; Spend a few minutes to hours =
someday having this be your new gestalt.&nbsp; Do any aspect shifts occur?<=

cording to said book, threatened Popper with a fire poker, although in my c=
amp's telling, he's doing another Zen koan type gesture, saying language is=
 a lot more than we're able to say.<br><br>As a thought experiment in my 19=
80 About Wittgenstein thesis, I had a non-sentient AI GPT computer named Ad=
am speaking through all human beings, saying "I" this and "I" that, but not=
 really having subjectivity.&nbsp; Adam =3D Language. Of course back then I=
