Mathematic & Logic


(R.1) Mathematics is the use of logic to create an abstract representation of is in the mind. It is a nimbus for which we have created an abstract language of its own for use in communicating the knowledge that results from its use.

(R.2) The most commonly produced abstraction of mathematics is numbers that we use for assessing magnitude or size which we shall call quantity. But the number itself does not describe any other aspect or property of the objective thing or things which are being quantified other than their quantity. And further, numbers are ineffable. They can quantify but cannot be described. Nature itself has no need of mathematics as it quantifies empirically.

(R.3) The language of mathematics enables quantification of abstract numbers. Examples include the operations of addition, subtraction, multiplication, division, vectors, matrices, calculus and statistics as well as many other even more abstract operations. That is, mathematics is a system of logic to quantify something that can be measured or counted as a number.

So how is it that we quantify? The base is what is called sets of things. As an example, let us suppose that {*} is a set that abstractly represent an apple or an elephant or another other thing. Similarly {***} would represent a set of {*} and another set {*} and yet another set {*} of apples or an elephants or another other things or even a set of an {*} apple and a set of an {*}elephants and a set of a {*} anything else. That is, {*} is a set and {{*}{*}{*}} is a set of subsets of {*}. And that is mathematics in a nutshell. We have abstractly quantified the existence of one or more things.

As a shorthand for sets we give each possible set a token symbol. The set {*} we designate as 1 (Hindu-Arabic) or א (Hebrew) or I (Roman) or many other different token in other language. But they all represent the set {*}. Similarly, for the set {***} we designate as 3 (Hindu-Arabic) or ג (Hebrew) or III (Roman), etc. In the language of binary code used with computers we represent {***} as 11. In the decimal notation we use in our daily lives to quantity, say money, we use $3.00 to represent the set {$$$} of dollars. The $ being the set of 100 ¢, the set for $3.02 would then be the set including the subsets {{$}{$}{$}} and {{¢} {¢}} or {{$$$} {¢¢}} which we would use spoken and written language to communicate the quantity three dollars and two cents of money in terms of material dollars bills and pennies.

More abstractly, three dollars and two cents can be stored in a computer as the binary number 100101110 representing credit for the buying power of 302 cents. Both the dollars bills and pennies and the binary number stored as credit in the computer have the same quality, which is power to used for the action of acquire something, say a cup of coffee. In electronic transactions, the binary number 100101110 is subtracted from one account and added to the "account" owned by someone else even though nothing material changes hands. Only the abstraction of value was exchanged as measured in pennies resulting in the transference of buying power by the action of two equivalent changes in the material memory of computers. Thus, the mind perceives the nonmaterial concept of credit which exists only as a number stored in the memory of a computer in a bank (or written on a promissory note like US paper currency). The only human involvement was the use thought to expedite the action of the transaction.

Both the sets and their token names are nnimbus and can take no physical actions. They cannot add {*) plus {*} plus {*} to equal the set {***}. We can only logically communicate that they do and equate them in memory as such. We must remember that 1 plus 3 equals 4. Show them to a tribe of natives deep in the Amazon jungle who have had no knowledge of numbers and they would be meaningless. The only quantities they know are 0, 1 and more than 1
to which they ascribe no tokens.

We can also perform mathematical operation with sets. We can subtract one set from another to obtain a remainder set: {****} minus {*} is the {***} set. We can multiply sets to obtain a set of sets: {***} sets of {**} set is the {******} set. And we can divide sets of sets: {******} set divided by {**) set is the set {***}. We can do logic of equality of sets: {***} is the same as {***}: true; (**} is the same as {***}: false; {***} is true and {***} is true: true; {***} is true but {**} is not true: true: etc. All of mathematics, however sophisticated, are based on these simple concepts. It is only a matter of learning the mathematical systems they employ. And, yes, even the most advanced computers use these simple concepts and depend upon tables sets to know that 2 plus 3 equals 5 and upon logic hardware to know that 2 plus 3 is not equal 6.

Alas, it has been logically proven that a complete and consistent set of axioms for all mathematics is impossible and even mathematics has it unknowable. Considering that all sets are subsets of sets (save the null set which contains nothing at all), it begs the question of what is the set of all sets?

(R.4) The language of mathematics also enables definition of special shapes or forms which we call geometry. Example of geometry include points, lines, areas and volumes in the three dimensional world with which we are most sentient. But geometry also includes not only these dimensionless points, one dimensional lines, two dimensional lines, and three dimensional shape of the sentient world but also the abstract four and higher dimensional geometries used primarily by those who study the world of the very small that lie beyond our direct observation with our sensory abilities. As an example, a the shape of a donut has a four dimension geometry.

The mathematics of these abstract geometries is beyond the experience and, thus, knowledge of other than a small number of mathematicians and scientists. Only the knowledge gained using them will be commonly known by most of us. The discovery, for example, of the Higgs boson was widely published but the mathematics and geometries used to predict its existence was not.

(R.4.1) Geometries other than three dimensional geometries may exist in sentient three dimensional space. Common examples are the two-dimensional geometry of the Mobius strip that exists in a three-dimension space and of the four-dimensional donut that exists in three-dimensional space. But humans are limited to the sentience of three-dimensional space. We only experience "up", "down", and "back". It challenges our mind to observe that a Mobius strip has a geometry with only one surface or that a donut has four dimensions.

(R.5) The language of mathematics enables the representation of the distribution of actions in time intervals both in time past and time future. This we shall call this the mathematics statistics. We would say the probability of a coin landing heads is 1 in 2 and similarly 1 in 2 of landing tails for a total probability of 2 in 2 or 100%. But this is true only for a two-dimensional coin. The coins in our pockets are three-dimensional coins with a heads surface, a tails surface and an edge surface. The total probability is the sum of the probabilities on landing on each of the three surfaces, that is the probability of heads or tails is less 1 in 2 because it can land on its edge and occasionally does. The same can be said for all geometries of any dimension.

The determination of actions at the quantum level at time present is impossible because they are entirely random. We can only say that the probability of an action at the atomic level in a time interval has determined value of probability and that the sum of all probabilities in all time intervals, past, present, and future, has a value with the absolute certainty of 1.

(R.5.1) With sufficient knowledge of cause and effect, probabilities are calculable. The mathematics of the Boltzman equation for the statistics of the relation between entropy and probability is an important example in physics. In an application of everyday experience, it quantifies the flow of heat from a hot stove to your hand when you touch the stove and the change in temperature that you sense. Without the statistical probability of heat flow from heat source to stove would not get "hot" and without the statistical flow of heat from the stove to your hand, you would not sense its hotness. And without the statistical flow of heat there would be no change in entropy, no change in anything, and no perception of time.

(R.6) Mathematics is not essential for our existence because nature does its own calculations empirically according to the laws of nature. Indeed, the earliest know mathematical systems are only about 3000 years old. But mathematics is very helpful in gaining our knowledge and understanding of what we call nature.

(R.7) Our perception of quantity diminishes as the numbers get larger. We are very good at perceiving the quantities of 0 and 1. A thing is either there or not there. With 2 we perceive it is more than one. Beyond that we begin to count to know the quantity. Perception of a quantity of 10 is difficult. Quantities of one hundred, one thousand or one million are beyond our perception of a thing that exists only as a collection of things; that is to say, as a set of things. Similarly, our ability to recall the abstractions that are numbers stored in memory is limited. About the best we can reliable do is about 7 numbers but even them we divide the telephone numbers for each individual telephone into two sets, one of three numbers and another of four numbers. And as the area code, we do not associate it with a specific telephone number at all but with a specific area where individual telephones are located.

However, we frequently use perception of quantity. We might only need look at an article of clothing to assess whether it is too large or too small in size for the intended wearer.

The ability of groups to quantify by perception can be somewhat accurate. As an example, 73 students were asked to guess the number of jelly beans in a jar. The actual number was 1116. The guesses ranged from 250 to 4,100, with an average error of estimation of the 73 guesses made by each of the individual students of 700 or 62% of the actual quantity. But the average of all 73 guesses of the group was 1,151 with an average group error of estimation of only 35 or 3% from the actual number. And, two of the students got closer than the average error of 35.

Even spiders use their primitive brains to quantify the size of its captured prey by perception. This is done to quantify the amount of venom needed to be injected to kill its prey because replenishment of venom by the venom gland can take days if all is expended in a single bite.

Humans do the same thing by quantifying the weight of an object to be thrown and the distance to the waste basket in order to quantify of the force be to exerted by the muscles in the arm and hand that the object might fall into to the trash can. And, indeed, basketball players do exactly the same when shooting a basketball. In all cases the action is performed with the intervention sensory information with the brain.

(R.7) Numbers can exceed comprehension by the human mind. Infinity, designated by the token ∞ is boundless, endless, or larger than any natural number (1, 67, 194674, etc) we can count. Infinitesimal calculus developed the late 17th century is the mathematics used in every branch of the physical sciences, including computer science, statistics, engineering, economics, business, medicine and demography is base around the concept of the infinitely small.

Imaginary numbers created by multiplying a real number that an imaginary unit i which, when multiplied by itself is equal to -1. Although imaginary numbers have no material association as do other numbers used for counting, imagine numbers are essential in understanding and quantifying the material properties of subatomic particle in quantum physics.

Irrational numbers are real numbers that cannot be written as a simple fraction. The best know and most used of these is the ratio of the circumference of a circle divided by its diameter. Designed as π, this number is used extensively throughout all of physics and mathematics. It begins as 3.14159265359… and continues without repeating a pattern of numbers to what is believed to be an infinite series of number of fractional numbers. Or, at least, π has been calculated up to series of 62.8 trillion numbers without finding a repeating pattern.

Another irrational number φ is known as "golden ratio". Equal to 1.618033988749... , it is found in numerous cases in mathematics and geometry often associated with the aesthetics in the visual arts and has been used by artists and architects for that purpose. Approximations of the "golden ratio" are to be often found in nature. Examples are the is spiral shape of a nautilus shell and the ratio of the lengths of the adjacent phalanx bones in the hands and feet of vertebrates. In all cases, these incomprehensible numbers always relate to some aspect of reality for which we can comprehend.

Summation

(R) Logic is a system used to create abstractions of relationships between things and/or actions in the mind. Mathematic is a system of logic to create abstractions of quantity in the mind. Both are used in reasoned thought to reach logical conclusion upon which to base knowledge and action. Neither is complete can lead to unsolvable paradoxes. Yet both serve us well in meaningful ways to obtain scientific knowledge.
