Re: Understanding soundness/completeness as "validity classification"?

] Def. **Completeness** is a property of *proof methods*, ie. a given proof method is either complete or incomplete. If a proof method is "complete", then whenever the method indicates that an argument is invalid, we can be sure that it is indeed invalid. In other words, the proof method ...

Re: Is the US President supposed to represent all the people?

Now for the fog. Now it’s all about diluting the language, redefining words to redefine legality, shifting attention to other news topics such as attacking Trump. The narrative goes from "I didn't do anything," to "I didn't do anything illegal." But the latest from the left is t...

Re: Factorial pattern

Besides number theory, I'm drawn to calculus, differential equations, linear algebra and some topology plus some algebra too. I like to experiment and explore. Sometimes I turn up something which is worth further exploration (at least to me). When people say they don't like math or find it hard, so...

Re: Factorial pattern

I was already aware of the chord example you brought up. Some patterns are finite and others are infinite. I consider patterns as guidelines for further exploration which can lead to exciting math. Which branches of math appeal to you? Unpatterns. Mathematical objects that have no patterns at all. ...

Re: Factorial pattern

Now you're contradicting yourself. You're saying the first five numbers make a pattern (which I agree with). Next you're saying the 6th number breaks the pattern and is just a coincidence. But the pattern must exist to be broken, otherwise it can't be broken. So in your example, you do have a patte...

Re: Factorial pattern

To mention, when you said "tiny-data set", that implies you know what I'm talking about and you agree with me there is a pattern. How do you figure that? I don't know what you're talking about, I denied there's a pattern, I pointed out that math is full of numerical coincidences, and I li...

Re: Factorial pattern

1! = 1 3! = 2•3 5! = 4•5•6 7! = 7•8•9•10 The dot means times. This pattern doesn't extend beyond 7! What pattern is that? Your expression for 3! starts with 2; your expression for 5! starts with 4; but your expression for 7! starts with 7, not 6. And your expression for 1! starts with 1, not 0. The...

Re: Is Trump our first FAKE President? (US)

Symptom of a broken system. The bipartisan consensus that's had us stuck in half a dozen wars in the Middle East and North Africa for 15 years and no end in sight. The permanent welfare/warfare state living on borrowed and printed money. It's gotten so bad that even the public is catching on. Trump ...

I'm currently learning Spanish (not very well sad to say) and the word for language is idioma; and the word for idiom is modismo. Go figure.

Re: Is 0.9999... really the same as 1?

I was interested in the later bits on skepticism and the alternative number systems where it doesn't equal 1. Oh I see. Well this fits in with something I keep saying. If we defined the symbol .999... to mean 47, then since 47 is different than 1, it must be that .999... ≠ 1. Of course all these al...

Re: Is 0.9999... really the same as 1?

This seems to cover the general discussion and points to where the confusions may lie. https://en.wikipedia.org/wiki/0.999... The skepticism part seems apt but it appears that one can have 0.999... less then 1 if one is prepared to give up some very useful parts of mathematics and even then this ap...

Re: Is 0.9999... really the same as 1?

Am I required to weigh in here? Surreals, ok. This looks promising Promising what? I confess I'm at a loss to follow your point. Promising a dramatic refutation of the previous two centuries of math? I'd say you've done no such thing. Perhaps if you stated a clear thesis or argument, we could analyz...
