"The true metaphysics of the square root negative 1 remains elusive." - C.F. Gauss

If you'd prefer to put the word "imaginary" in quotes, that works, or you can use the word "cyclic". It's math so you can use whatever words or labels (or language) you wish ... but that means that Cypress and others get to use whatever words they wish.

I'm not playing word games. What 'imaginary' component????

I think you understand that as long as the formal expression is unambiguous, it doesn't matter what words are used when spoken. In fact, deaf mutes can work with complex numbers just fine.

So?

Infinity, as a quantity, can be larger than another infinite quantity.

Infinity isn't a quantity. It has no size.

What happens when an error is produced? Who's responsible? Do you remember the Space Shuttle explosion of '86? Maybe someone tried to take the square root of a negative number. Sometimes when engineers make insidious errors, people die, or there are electrical disasters, or devastating fires. Is that sufficient concern?

Nope. They simply launched that shuttle in weather too cold for the O-rings sealing booster sections.
Unfortunately the leak that developed was facing the hydrogen tank.

Effectively pilot error.

I lost interest in 11th grade math in the 12th grade.

You and so many others!

Good choices. The world needs mechanics and ditch diggers too. From what I can tell, only about a third of the population of any country, at most, is college material. Another third or so are people who can do skilled trades that are every bit as important to a modern society as skills derived from college. Then there's the last third. The world needs hairdressers and janitors too...

It's rather revealing that tradesmen make more money than college dorks.

I think the only exceptions are doctors of medicine and few types of engineers.

Note that I consider software development a trade.

And yet it is done. And a field is created out of it. Many applications.

Not possible. No 'field' is created out of what is not possible. No application is created out of what is not possible.

It's like beating a dead horse, eh?
Some people are incapable of learning. From your link:

Your bullshitting isn't working, Sybil.

I actually knew a chem. eng. grad who went on to be an Opteon sales rep for Dupont .
You certainly don't need a chem. e. degree for that !
I also knew quite a few accounting grads . Very, very few stayed in it because they hated it. Most that stayed in still hated it and a small percentage of them actually liked it and did what I consider "OK".

You have no idea how many discussion groups I am in.

I’m mildly curious. About how many?

No answer.

I think you're right. He IS Dutch's sock. Internet addiction syndrome - IAD.

1) "There are actually many different sizes or levels of infinity; some infinite sets are vastly larger than other infinite sets."

2) "Strange but true: infinity comes in different sizes."

3) "As German mathematician Georg Cantor demonstrated in the late 19th century, there exists a variety of infinities—and some are simply larger than others."

Here's the simple proof that there must be multiple levels of infinity

A crucial concept in mathematics.

If you were counting on infinity being absolute, your number's up

So?

so stop playig word games.

so stop playig word games.

Would that be something like

Wordle - A daily word game

Guess the hidden word in 6 tries. A new puzzle is available each day.

That's only true for the set of real numbers,

Nope. You and Trumpet are flat out denying math just because you both believe everything you read on the internet. All you had to do was to look up the mathematical proof that i does not equal -1, but as you demonstrated, learning is simply too much work for you.

I've only been talking about numbers

You were talking about visualization and conceptualization.
