Well..one of the most mystrious numbers...along with pi, 1, 0, an the nuber created by the Golden Ratio...
Discuss infinity-related stuff here. I also heard that the TI-89 and some other calcs have an infinity button.

All 68K calculators have an infinity function.
Please note that undefined (68k only) as a solution may mean +-infinity.

I also heard that the TI-89 and some other calcs have an infinity button. Infinity is not considered a "mysterious number" if you mean "important and mysterious number". In reality, it is useless. an the nuber created by the Golden Ratio... This interesting number is called phi. And you forgot e, the base of the natural logarithm.

"e" is interesting too, and is used in physics, chemistry, and even astronomy I think.

No, e is used in Math. Math is used in Physics. Physics is used in Chemistry and Astronomy....

This is true.

e is important...and that is why it is in most scientific and graphing calculators (if not all).

Thank you for stating the (hopefully) obvious.

Um...yeah. The last 5 posts or so were pointless/not very important. Anybody know how the infinity sign got invented and the person who made it? I can see the logic behind the symbol but I wonder if that is the same reason whoever invented the symbol made it that way.

It may be that the infinity symbol originated from the twisted shape of a Möbius strip because if someone walked on one, one would walk forever. But, the symbol was being used even before August Ferdinand Möbius discovered the Möbius strip. Others say that it was made from the Etruscan numeral "CI<insert backwards C here>", which meant 1000, and was used to mean "many".
The second question: "The Yajurveda (c 1800 BC - 800 BC) states that if you remove a part from infinity or add a part to infinity still what remains is infinity. The Jaina mathematical text Surya Prajinapti (c 400 BC) classifies all numbers into three sets: enumerable, innumerable and infinite."

Maybe. I understand that the infinity symbol can be written over itself again and again, wihout changing directions of lifting your pen up.

Naturally. It's a loop!

Post by bfr on Sept 3, 2005 8:54:54 GMT -5
Yeah. But I still wonder who thought of it.

Not that it *really* matters.

Post by bfr on Sept 5, 2005 10:00:48 GMT -5
Yeah, but on the other hand, many topics on this forum don't *really* matter.

That was a useless post. At least say the correction and then post something relating to the topic. If I made one of those one-word posts I might get my post deleted.
I think infinity is a cool number (or whatever it is). In 6th grade, me and my friend used to quiz other students about infinnity and then laugh at their dumb mistakes. Also, my friend and some other guy got into an argument about if .999... (repeating) is equal to one or not.
