Scientific Principles are Common Sense
My main purpose for writing this article is to show that principles of science are not only common sense, but can be used to facilitate the teaching and learning process in school. Once the student becomes fluent in the scientific laws, his comprehension level should increase at a faster and more effective rate. I firmly believe that scientific principles should considered pillars of learning, not only science, but other subject areas. Scientific principles can be observed in all walks of life. They even relate to the amorphous subject matter of human behavior in many ways, especially in a common sense manner.
Take for example, the law of conservation of matter and energy. It has been in existence for the longest time. It also includes the elements of time and space, matter and energy. The law of conservation is based on the premises that matter and energy are constant; neither can it be created nor it can be destroyed. Matter and energy just change form and position in space through time by chemical or nuclear change. For example, as you burn a cigarette, it changes into carbon and gases. From this concept, a generalization can be made: when matter disappears from one space (place), it must appear in an other space (place) and another time in the future! This generalization relates to the property of matter that deals with the occupation of space on the one-to-one correspondence in which one unit or amount of matter carries its space all the time and cannot exist in two places (spaces) at the same time!
The principle described above can be associated to the concept of the alibi in criminal justice in the area of criminal investigation. If a suspect (matter) claims that he was at place X at time T, when a crime was committed, then he could not be guilty of directly committing an act that was committed at place Y at the same time T, unless he is superman. However, an alibi has to be confirmed as part of an investigation before it can be accepted as an alibi. This is the part that the layman sees as common sense! And yet it is based on an elaborate sophisticated natural scientific principle: the law of conservation of matter and energy. (This is where the concept of “a perfect alibi” came from.)
How does the law of conservation of matter and energy relate to finances? This should be easy to comprehend based on your previous knowledge related to the topic (PKRT) of money. For example, if a group of ten persons are given one hundred dollars each ( This part of the example reflects the one-to-one correspondence principle.), the total amount of one hundred dollars for the whole group can be seen as constant for the purpose of the hypothetical situation. Money is matter in the form of value and material.
In this example, I have created a unique “universe of a money situation” in which no more money can be created (generated or added in this case) or destroyed (disappeared). Thus, if a (one) member X of the “universe group of ten persons” gives away thirty dollars from his amount to someone else, then a conclusion related to this situation can be stated in this manner: if money disappears from one place (from the pocket of member X), it must appear in another person’s pocket! Money does not necessarily have to stay within the group’s universe. The money (matter) can change position (space) at any time T and wind up in the pocket of a pick pocket or a member of the original group of people mentioned in this example.
A Common sense conclusion from the law of conservation can be made in this manner: when money disappears from your pocket, it will appear in someone else’ pocket. The converse (opposite nature) of this common sense observation can be expressed in this manner: when money “appears” in one person’s pocket, it is because that money “disappeared” from another pocket!
Another example where the principle of the law of conservation can be observed relates to the reason why deer are seen grazing on the side of the highway more so than in the pasture areas. According to a high school agriculture teacher, it is because plants and brush and trees compete for the nourishment in the soil. And guess which plants takes up more of the nourishment which is considered to be constant? Of course it is the trees and the brush. Thus nourishment in the soil appears in the trees and brush, it will not appear in the grass. This is another way to express the same principle of the law of conservation since nourishment contains both: matter and energy.
This explains why deer like to graze on the side of the road. The grass is, not only greener on the side of the highway, but a little better nourished since it does not have to compete for the nourishment or for the moisture from the ground. Of course this is common sense!
