What we in the States would call "The Golden Ratio"...., Thanks Jan..., nice 
one.

Well..., I got distracted by errands this afternoon (not the least of which 
was a last-minute evisceration of a pumpkin), and never got back here with a 
promised 'interesting' math exercise. And for those of you not surprised to 
find Euler's number hanging about in a collection of random numbers, *this* 
one might surprise you:

Sum the following series: 1+(1/(2^2))+(1/3^2))+(1/4^2)........, and so on, 
for say, 600 terms. This *is* a convergent series, and is rather famous. At 
any rate, 600 terms will produce a good result..., but not a recognizable 
result for any normal person. What is necessary is to take the square root 
of the *product* of 6 times the result, i.e., sqr(x*6). *That* number you 
will recognize...

Pick a number, any number : A
Pick another number, any number larger than A : B
Add A to B : C

Divide C / B : "d"

Ooops..., gotta watch those parentheses.... should read

1+(1/(2^2))+(1/(3^2))+(1/(4^2)).......

Re: trouble with hyperterminal

John, that worked, and indeed not only with 300 baud but also with
19200. What is the official way to stop TEXT waiting for new data from
the COM port? When I saw the last transmitted line appearing on the HT
window I started to hammer randomly onto F3 and F8 on the laptop.
After a while I found myself in the main menu, but I guess there is a
better way then this?
Next thing (and probably last thing before installing teeny again)
would be to try with this other HT version.

No, not needed............, just a petty obsession on my part.Yikes..., I'm

RE: Pick a number (Was : RE: M100 Halloween mystery)

There's at least 50 different series that can be used to calculate PI.  All
based on arctan (x) = 1 from what I can tell.

Interesting.

Hmm... I am not sure I remember accurately, but I believe it is the
laptop's Break key.

Alternatively you could append an EOF character to the text file you
are transmitting or just send an EOF character from the keyboard on
Hyperterminal.

    This particular series is important because Euler proved that it is a 
closed form, that is, that the limit is Pi. The Wikipedia has a short but 
succinct entry about it (http://en.wikipedia.org/wiki/Basel_problem ) . I 
find this (and some others) fascinating, simply because there is *no* 
geometric reference to be seen anywhere nearby....

WARNING..., if you read beyond the Euler bit, into the discussion of the 
Riemann zeta function, there is a certain risk of being lured into 
contemplation of the Riemann hypothesis ( 
http://en.wikipedia.org/wiki/Riemann_hypothesis )....., swampy ground. I 
defer to Tristram Shandy's appeal to his uncle to abandon the effort to 
figure out the location of the cannon which caused him a war wound:

"Towards the beginning of the third
year, which was in August, Ninety-nine,
my uncle Toby found it necessary to un-
derstand a little of projectiles : -- And ha-
ving judged it best to draw his know-
ledge from the fountain-head, he began
with N. Tartaglia, who it seems was the
first man who detected the imposition of
a cannon-ball's doing all that mischief
under the notion of a right line. -- This
N. Tartaglia proved to my uncle Toby to
be an impossible thing.

Truth !

Good advice from old Tristram; I shall make a most valiant effort to avoid 
being lured into contemplation of the Riemann hypothesis even though 
I have no wound upon *my* groin that I'm aware of...
