A topic to elicit some thoughts....
How important is mathematics to you as an engineer?
It ranks surprisingly low on the pecking order.

Definitely not. My sister (has a mathematics degree) is razzing me
about that all the time but that's just how I am. IMO engineering is
mostly instinct. People who don't have them can't be good engineers.
Instinct comes with practice, lots of practice.
By definition, anything that only comes with practice is *not* instinct.

You are correct, though it is rather muddled in scientific literature:

https://www.edge.org/response-detail/11453
Also, that article relies on some basic fallacies. The most obvious one
is this:

"the capacity to learn that language is a human instinct, something that
every normal human child is born with, and that no chimpanzee or gorilla
possesses."

Clearly false, since there are chimps who have been taught complex sign
language (hundreds of words), who converse. and who invent new words and
teach their children to do the same.

That's a rather controversial claim. Quite a few people are less than satisfied with the evidence which was bought forward to support it. Whatever it is that chimps do, they do it a lot less well than humans, though it does seem that the human capacity invent and learn languages is just a more highly developed version of the system that most of the more highly evolved vertebrates have.

A rather strange error for a
"Professor of Cognitive Biology" to have made.

It's not an error. More an expression of practical reality.

Cats don't need to be taught to hunt - but they do need to be taught
*how* to hunt. People don't need to be taught to invent - but they can
be taught *how* to invent.

Human language acquisition is mostly working out how everybody in the immediate vicinity uses language. The way you listen to language is heavily influenced by the language (or languages) you heard when you were an infant. The first six months are devoted to learning which features you can ignore.

We did work with one big semi manufacturer together once, me as an
equipment provider and he as a consultant to them. We haven't done
much else except help one another and share information. We are
complementary in that I have a lot of crazy ideas and he has the math
skills to shoot them down.

He did help me recently with my triggered Colpitts oscillator. I've
shared measurements on phemts and things.

Both our wives are called Mo.

I've met and like several people who post here. Speff, James, Joerg,
you. People who actually design electronics seem to get along for some
reason. People who don't, less so.

But James is weird. He skis in short pants.

Sign language isn't speech, but lots of people use it for conversation.

Speech researchers do study it, and for all practical purposes it is a kind of speech.

(hundreds of words), who converse.

** Utter bullshit.

It's actually a controversial claim, but the controversy it about the quality of the conversation taking place rather than any idea there wasn't a conversation going on.

It's more like an apes brain than any other vertebrates brain, but then again so is yours.

Hey, don't be too sensitive, I'm just poking fun. I actually admire you
in the "play" aspect of inventing stuff and have used it a lot in my
career too.

Edison reckoned he found many different ways to not make a lightbulb,
too. I think that's important. Systematic approaches to design only
works after you have enough experience to systematise things. When
you're expanding frontiers, the approach only works for the support
stuff, not for the core innovations.

ľ - "Latin-1" "micro sign". code point U+00B5

The micro sign (from Greek) was already in DEC MCS (Multinational
Character Set) at position 0xB5 to indicate 0.000001.

ISO 8859-1 adopted the DEC MCS nearly completely. The ISO-8859-1 was
then nicknamed Latin-1 That nicknaming doesn't make 0xB5 Latin.

This one is Greek

? - "Greek" "lower case Mu" code point U+03BC

I assume you are referring to ISO 8859-7 as "Greek",

It has that symbol among ordinary greek lower case letters.

Please note that ISO 8859-7 doesn't have the micro symbol in position
0xB5.

https://en.wikipedia.org/wiki/Greek_alphabet

Completely different from the Latin alphabet.

https://en.wikipedia.org/wiki/Latin_alphabet

Micro- (Greek letter ľ or legacy micro symbol ľ) is a unit prefix in
the metric system denoting a factor of 10-6 (one millionth).
Confirmed in 1960, the prefix comes from the Greek ľ????? (mikrós),
meaning "small". The symbol for the prefix comes from the Greek
letter ľ (mu).

I guess I just said Latin because medical and math uses it so much.

My next line is supposed to be:

"It's all Greek to me."

Alt Gr m??? We have no Gr key over here, boy! (Foghorn Leghorn)

And it is easy to tell why.

And easy to rememeber why.

The ALTernate character set is not part of the main 128 character
set, and is accessed on a perfectly NORMAL keyboard using the alt key
and a numeric sequence that ALL personal computers started with.
What the fuck a "Gr" key is we do not know. But I can assign
keyboard shortcuts as I wish without the need for some strange
character.

ANY "user" of ANY computer should possess enough brains to learn
basic computing paradigms, or be relinquished to asking others for
help. But the text substitute thing is bad.

U R Stew Pid and LOL and all that crap is really dumb. TYPE IT OUT.

That's the same realm we got pants down past the asscrack stupidity
from. And any odd keyboard layout adopted since the AT spec emerged
are the odd men out, not us. And if Linux or BSD does not allow me
to simply tyrpe in the standardized alt + numeric to get an otherwise
unavailable character up, then fuck them too.
