Beware of the word INFINITY !!

1. The Infinite Circle

Nicholas of Cusa (1401-1464) made the following interesting point regarding the shape of an infinite circle. The curvature of a circle's circumference ecreases
as the size of the circle increases. For example, the curvature of the earth's surface is so negligible that it appears flat. The limit of decrease in curvature is a straight line.

An infinite circle is therefore... a straight line!!!!!


2. The Racetrack (or Dichotomy)

I can authoritatively say that one can never reach the end of a racecourse, for in order to do so one would first have to reach the halfway mark, then the halfway mark
of the remaining half, then the halfway mark of the final fourth, then of the final eighth, and so on ad infinitum.
Since this series of fractions is infinite, one can never hope to get through the entire length of the track (at least not in a finite time).

Start ____________________1/2__________3/4_____7/8__15/16... Finnish

But things get even worse than this...
Just as one cannot reach the end of the racecourse, one cannot even begin to run. For before one could reach the halfway point, one would have to reach the 1/4 mark, and before that the 1/8 mark, etc., etc. As there is no first point in this series, one can never really get started (this is known as the Reverse Dichotomy).

3. The Paradox of the Divided Stick

This is a big one..Ready??

This is a modern version of a plurality paradox asks what would happen if an infinitely divisible stick were cut in two, then half a minute later each half were again cut in two, then a quarter of a minute later each fourth cut in two, and so on ad infinitum.
At the end of one minute what would be left? An infinite number of pieces? Would each piece have any length?

From your answer lets continue...
This brings us to the two of the better-known plurality paradoxes :

(1) If something is divisible (the stick), then it is infinitely divisible (ie the stick can be divided into an infinite number of pieces). Now if each part has zero size, then the total has zero size, for an infinite number of zero lenghts add up to zero. If on the other hand each part(of the stick) has some finite size, then the total is infinite, for an infinite number of finite lenghts, however minuscule (small), must add up to an infinite total. So something divisible is either infinite or else has no size at all. Thus something finite is not divisible [the stick is not divisible]!!!!

(2) The total number of things is both finite and infinite. It is finite because, if there are many things, then there must be as many as there are "neither more nor less". And in that case their number is limited, hence finite. But on the other hand if there are many things, they must be infinite in number, for between any two there must always be others, and between those others still, and so on. (This paradox
apparently is meant to apply to spatial points, rather than to physical objects.)


4. Paradox of the chinkororo* [No pun intended]
This version of the Racetrack paradox brings out the conceptual difficulties inherent in infinite tasks. Suppose Paul Tergat wants to run the length of a racetrack but there are an infinite number of chinkororo (Tergat is not aware of them) who have the following intentions: the first chinkororo intends to paralyze Tergat if he reaches the halfway mark; the second intends to paralyze Tergat if he reaches the quarter mark; the third, if he reaches the one-eighth mark; and so on. As in the Reverse Dichotomy (last bit of paradox 4 above), Tergat cannot even start running: to do so would violate the intentions of an infinite number of chinkororo. However, it is not clear why he cannot start running, for until he does, no chinkororo has actually paralyzed him.

Jargon Critic

1.
“think outside the box.” what fricken box?! what’s in it to start with?!

I’m at school. I hate thinking outside the box. It’s cold out there. I want to be inside the warm box.


My Calculus lecturer used “outside the box” alot too just like many other have brought it up. The box? I am so good I never have seen the box!


2.
Oh, and “utilize”. And “orientate”. What’s wrong with “use” and “orient”?


3.
“Over-qualified.” Used only by those who are under-qualified.

4.
“Rubric” as it is now used in schools. The same institutions that put limits on vocabulary-building so that the average student can barely hold an intelligent conversation, have the gall to use the word “rubric”? It turns out it means… instructions. Steps for completing the assignment. I find words to be rather delightful, but there’s no need to fix what ain’t broke. Replacing “instructions” with “rubric” does not impress me.

5.
“best-practices” is the worst.
I don’t think it’s the best practice to use best-practices. It sounds ridiculous.

6.
I’ve seen the word “Quixotic” way too much in the past week.

7.
My old boss said “diligent” all the damn time. I was pretty diligent in my hatred of the word and cringing of his use of it! It was as if he invented the word…like he just learned it in english class and had to show off.

8.
“Pragmatic approach” - Why does a word that mean something practical, sound so impractical? As soon as you hear this saying you know the PITAF (pain-in-the-ass-factor) is gonna be HUGE!!

9.
“Developing new synergies/ strategies/ markets/ ….” - Dip shit in candy and paint it pink and white. At the end of the day it still comes out as shit.

10.
I’m tired of “Rubenesque women" and "Chubby ladies". “Fat chicks” is much more direct.

11.
Also why must everything have its own “vision and values” and why must every sports team play with “Pride and passion”. Even Harambee Stars played with pride n passion when they lost to Taifa Stars!

12.
Oh, and our workplace have just dredged “core competencies framework” out of the pond to assist in the annual review process. Its a bit moss covered by now that phrase, but thats when they join our lexicon here.
