we have

∀n ∈ ℕ: 1/n - 1/(n+1) = 1/(n(n+1)) > 0 .

note the universal quantifier. This holds for every unit fraction. Thus for every unit fraction (unrevealed or invisible or ...) there is another unit fraction closer to zero (the gap is finite.),

Thus the is no first unit fraction.

William, infinite spamming nutjob comparing unit fractions of Moscow compared to Beijing. William spamming nutjob is Moscow 0/1 and Beijing fraction is 1/0 ??

yan wyck in his daily spam says Beijing was nothing in 1999 and apparently a Russian Sarmat returned Beijing to "nothingness once again".

Yes of course, considering that Russia had stolen the lands of Outer Manchuria, some 28 times larger of a land mass than is Taiwan island. Yet there is Xi, spending so much time on wanting to invade Taiwan, when it is Outer Manchuria and Vladivostok (Haishenwai) that he should be focusing attention upon. And while Putin is distracted with Ukraine, is the time for Xi to recapture Outer Manchuria, the Qing dynasty empire, Qing's Manchurian homeland.

This easily can explain the light-headed reasoning that Xi and his foreign diplomats Wang Yi display, where Putin plays them like a chess game, --- checkmate in 7 moves.

The sequence (1/n)_(n e N) does not converge?

0 is not its limit? (i.e. lim_(n -> oo) 1/n =/= 0 ???).

Trying to do the Mückenheim?

You are talking nonsense, man.

(Another hint: We usually don't restrict our consideration to the rational numbers when talking about the convergence of a sequence of real numbers. The sequence (1/1, 1/2, 1/3, ...) concerges, and its limit is 0.)

You know there are books and online courses/tutorials from which you
could learn what a limit is? Getting "closer and closer to zero" does

not mean that zero is the limit. Don't get me wrong -- zero /is/ the

limit in this case, but if you were a student of mine I'd invite you to

define a sequence that gets forever "closer and closer to zero" but

which does /not/ converge to a limit of zero.

i[2] = i[1] + 1/4

No. I meant literally what I said. There no games or word trickery

going on. Find a sequence whose terms get closer and closer to zero but

which does not converge to zero. It's much simpler than you think.

Hint: for the terms of s(n) to get "closer and closer to zero" all we

need is that

|s(n+1) - 0| < |s(n) - 0|

Humm... For some reason I am thinking about alternating the signs of the

terms?

1/1, -1/2, 1/3, -1/4, 1/5, -1/6, ?

Damn, can't be right. I need to work on some other stuff right now, but

I will get back to you. Thanks Ben! :^)

1, -1, 1, -1

Not sure exactly why I thought of it.

picked one meaning for getting closer and closer to zero, and you can't

see any other.

it is true for every unit fraction that there is a second unit fraction between it and zero

May 29, 2023, 7:29:51 PMMay 29

to

i[0] = 10

i[1] = i[0] / 2

i[2] = i[1] / 2

i[3] = i[2] / 2

i[4] = i[3] / 2

i[5] = i[4] / 2

...

It gets closer and closer to zero. But, its not what you asked for.

closer and closer to zero, forever? What is the limit?

Oh dear. Then, according to you, there is another error in your book.

You give the set of rationals B = {x > sqrt(2)} and say that it has no

smallest element. Define NR(z) as the number of elements of B less than

z. Now NR(sqrt(2)) = 0 and NR(2) = many so the elements of your set B

start between sqrt(2) and 2. Never more than one occupy a point. This

enforces a first one, yet you say that B has no first element.

You give the set of rationals B = {x > sqrt(2)} and say that it has no

smallest element. Define NR(z) as the number of elements of B less than

z. Now NR(sqrt(2)) = 0 and NR(2) = many so the elements of your set B

start between sqrt(2) and 2. Never more than one occupy a point. This

enforces a first one, yet you say that B has no first element.
