In my case, the more irrelevant the printed thing is, the more the idiot will whine about it.

Taking a stand alone printer away from some of my users when they die is almost taking the first born based on the crying.

Has always driven me nuts that pi is an approximation.

Pi as a fraction is a real number not an approximation. Pi as a decimal is an irrational number and goes on infinitely, I think. If the above is true it might have to do with the mechanics of the number system we use, but I do not know how that could be.

Does using a larger infinity in solving an integral make it more accurate?

I’m sticking with the “One Size Fits All, Infinity”.

There aren’t more real numbers than integers because both lists are endless. Infinity is not a number, it means ‘endless’.

There are known knowns. These are things we know that we know. There are known unknowns. That is to say, there are things that we know we don't know. But there are also unknown unknowns. There are things we don't know we don't know

Known Knowns - Educated, I know what I know when I know it.

Known Unknowns - Scholarly research and study, I don't have the answer yet, but still thinking and looking for it.

Unknown Unknown - Village Idiot level of ignorance. (Democrat)

You can’t count to infinite, either in integers or real numbers.

Maybe not. If one can get enough taxpayer $$$'s then one can spend a lifetime trying! It beats watching the sex life of some toad.

As soon as one blurs the distinction between continuous and discrete quantities having a coherent discussion about what infinity means becomes meaningless.

Infinity with regard to discrete quantities means that there is never a greatest, you can always add one.

Infinity with regard to continuous quantity means you can divide it in any manner you please.

In computer science the distinction between continuous and discrete quantity has been for the most part preserved.

In modern “pure” mathematics the distinction has been obscured. This causes modern mathematics to become a grotesque exercise. Anyone who has endured a graduate level course in “real analysis” can attest to the stupid proofs that claim that the real number system can be constructed, it is absurd.

You can trace this back to Nicholas Bourbaki, aka the mathematicians that Hitler chased out of Germany. Hitler was a monster, but he was right about the corruption of mathematics.

The premise is that numbers are a real thing, rather than a human construct to keep accounts in approaching an unknowable reality.

Very qualified as an engineer. And I can prove it because I do not know how to spell Daisies.

Married an artist. She taught me how to appreciate the other side.

This would be the 2nd category - the known unknowable...

I miss watching Donald Rumsfeld chop off the heads of ignorant reporters.

Integers are countably infinite, real numbers are uncountably infinite. They are provably different, e.g. by Cantor’s diagonal proof. The number of rational numbers is also countable.

I have a proof for this, but there’s insufficient space to show it here.”
Thank you Monsieur Fermat
