Nothing is something
1. Nothing is something
Many people think of actions as having two choices, "
do it" or "
do not do it" - a logical fallacy called "
false dilemma". There is a third action that is at the heart of computer science.
1. "look and do"
2. "look not do"
3. "do not look" - it may not be necessary and, in general, "does not matter".
Efficient algorithms in computer science rely on knowing when to look and when not to look.
Good logical arguments do not include anything not relevant (needed) for the logical argument.
Doing nothing is something and can be important.
[Apostle John]
2. The gambler
In the 1978 hit song "
The gambler", Kenny Rogers sings about card game strategy where one needs to know that, without looking (keeping in the game) it may be necessary to fold. The song hit #1 on the country charts and became Kenny Rogers signature song.
You've got to know when to hold 'em, know when to fold 'em,
Know when to walk away, know when to run.
You never count your money when you're sittin' at the table,
There'll be time enough for countin' when the dealin's done.
3. A third alternative
Many people think of two choices.
1. Look and do it.
2. Look but do not do it.
A third choice is at the heart of computer science and statistics.
3. Do not look. There is a cost to looking. And it may not matter.
It may already be known what is there, or it may have been determined that it is not necessary.
4. Short-circuit conditional evaluation
This idea is used all of the time in computer science and programming. A simple example is that of conditional evaluation of expressions (i.e., no side-effects during evaluation).
In the expression A and B, if A is false, then one need not look at B.
In the expression A or B, if A is true, then one need not look at B.
It may be the case that evaluating
B may cause an error.
In discussions, it may be the case that
B is a "
red herring" and does not matter. The only thing that matters is
A. Here are some tautologies often used in programming (as algebraic transformations).
(A and false) = false
(A and true) = A
(A or false) = A
(A or true) = true
(A = true) = A
(A = false) = false = (not A)

6. Brute force
A "brute force" method looks at every possibility in order to determine an answer, property, etc.
This is to be contrasted to what might be called and intelligent method that need not look at every possibility.
Note that there are intractable problems (e.g., NP complete, NP hard, etc.) for which there is no known efficient solution that need not look at every possibility.
7. Example
A simple example is that of binary search of a list (e.g., represented as an array structure). If a list is in order (whatever order is defined and present), then if one picks an item in the middle and compares it to the value desired to be found (if it is in the list) then about half the list can now be ignored and one need not even look at that half of the list.
This continues in a recursive divide and conquer way until one either finds that element in the list or determines that the item is not in the list.
8. Twenty questions
The method of binary search is used in the game of "
Twenty questions". Twenty well-asked questions, where each divides the problem space into one part in one million. That is,
220 ≈
1,000,000.
This can be seen in bit terms in the following
210 = 1024 = 2*2*2*2*2*2*2*2*2*2
220 = 210 * 210 = 1024*1014 = 1,048,576 ≈ 1,000,000
9. Statistics
The field of statistics is based on the idea that one needs only look at a small part of the population (via a random sample) to determine properties of the entire population (to a high degree of certainty).
Those who do not understand this about statistics are tempted to look at every part of the population.
10. Computer science
Those who do not understand this about computer science are tempted to always look at everything, again and again, to determine the desired course of action to take.
11. Catch-22
An interesting sign is the sign in braille that says, "
Do not look at this". Obviously, someone who is blind could not actually look at it and someone who can see (and read) has already looked at it in order to understand the message.
12. Thinking about parking
The first time I saw a street sign that read "
Don't even think of parking here" my first thought was, "
ok, what if I park there without even thinking about what I was doing". Would I then be in violation of the sign?
Literally, one who "
does not think" about it would not have a logical issue parking there. Of course, what do I know. Maybe, like Socrates (or Sergeant Shultz), "
I know nothing". Does that make sense?
Should one be making decisions without considering the matter, or at least thinking about it?
13. Nothing is something in programming
Nothing is something.
Nothing is something.
Zero is a number.
An empty string is a string.
No decision is a decision.
No value judgment is a value judgment.
In computer programming, one should make sure the program works for the nothing part too.
14. Policies
Not addressing something is addressing it.
No policy is a policy.
Not making a decision to a decision.
Not making a value judgment is a value judgment.
15. Identity elements
An identity element for an operation is a value that when applied to an element using that operation returns that element unchanged.
The value 0 (zero) is the identity element for addition.
The value 1 (one) is the identity element for multiplication.
The empty string is the identity element for string concatenation.
x + 0 == x
x * 1 == x
Since an identity element returns the value unchanged, it has the effect of doing nothing.

τοτε επετιμησεν τοις μαθηταις ινα μηδενι ειπωσιν οτι αυτος εστιν ο χριστος [gnt]
An ancient Greek word for "
nothing" is the modern Greek word for "
zero".
The ancient Greek word "μηδέν" ≈ "not one" which is from the ancient Greek word "μηδέ" ≈ "and not, nor".
The modern Greek word "μηδέν" (mee-THEHN) ≈ "zero, nothing"..
31. Matthew 16:20
Matthew 16:20 Then charged he his disciples that they should tell no man that he was Jesus the Christ. [kjv]

33. Job 26:7 Nothing
Job 26:7 He stretcheth out the north over the empty place, and hangeth the earth upon nothing. [kjv]
εκτεινων βορεαν επ ουδεν κρεμαζων γην επι ουδενος [lxx]
Job says the earth hangs on "
nothing".
- *H1099 בְּלִימָה (bel-ee-mah') : from H1097 and H4100; (as indef.) nothing whatever:--nothing.
34. Job 26:7 Nothing
Job 26:7 He stretcheth out the north over the empty place, and hangeth the earth upon nothing. [kjv]
εκτεινων βορεαν επ ουδεν κρεμαζων γην επι ουδενος [lxx]
What is meant by the "
north"?
What exactly is the "
empty place"?
What is "
nothing"?
The Latin word "nihili" ≈ "nothing".
The Spanish word "nada" ≈ "nothing".
The Portuguese word "nada" ≈ "nothing".
35. Job 26:7
KJV: He stretcheth out the north over the empty place, and hangeth the earth upon nothing.
Hebrew: נטה צפון על תהו תלה ארץ על בלי מה׃
Greek: εκτεινων βορεαν επ ουδεν κρεμαζων γην επι ουδενος
Brenton: He stretches out the north wind upon nothing, and he upon nothing hangs the earth;
Latin: qui extendit aquilonem super vacuum et adpendit terram super nihili

36. Philippians 2:3 Nothing
Philippians 2:3 Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. [kjv]
μηδεν κατ εριθειαν κενοδοξιαν αλλα τη ταπεινοφροσυνη αλληλους ηγουμενοι υπερεχοντας εαυτων [gnt]
The ancient Greek word
"μηδέν" ≈ "nothing" and means, literally, "
not one". The modern Greek word
"μηδέν" (mee-THEHN) ≈ "zero, nothing".
How does one think about "
nothing"?
One sees a Kanizsa triangle but it does not exist. The idea of "
nothing" does not exist. It is just the perceived absence of what would otherwise be there. The philosophical question is "
Do holes exist?".
37. Nothing but a shadow
Colossians 2:17 Which are a shadow of things to come; but the body is of Christ. [kjv]
α εστιν σκια των μελλοντων το δε σωμα του χριστου [gnt]
Examples of "
nothing" or "
holes".
Keyhole (place to insert a key).
Donut hole (idea turned into an actual product).
Electrons and current as "holes".
Beer with "bubbles" going up and "beer" going down.
A
"shadow" is like a "
hole" in that it cannot exist without some physical object and some "
true light" source. A "
false light" is "
darkness". A
"shadow" has philosophical connections with Plato.
The Cat Stevens song "
Moon shadow" comes indirectly from the sun.
38. Colossians 2:17
KJV: Which are a shadow of things to come; but the body is of Christ.
Greek: α εστιν σκια των μελλοντων το δε σωμα του χριστου
39. Do not no way use double negatives
Related to the idea of "
nothing" is that of a "
double negative".
In "
correct" English, one is not to use double negatives.
I do not have none.
I don't have none.
I ain't got none.
Most languages of the world use double negatives to emphasize the negative aspect of what is being said. So too does Ancient (and modern) Greek. This can create certain translation issues in the
GNT (Greek New Testament).
A
double negative, translated as
"no wise", is used in Greek to be an emphatic negative as in
"absolutely no way".
"ου" ≈ "no" and "μη" ≈ "not".
"ου μη" ≈ "no not" and appears in 137 verses in the GNT. Aristotle uses this combination so it appears to be not just an Hebrew or Aramaic idea that shows through in Greek.
