Usually in the science classes given by the science teacher - different and diverse issues are given a brilliant solution and an ingenious explanation based on the essence of natural sciences, however, this time Dr. Mehini deviated from his usual habit, and explained to his young students who seek intelligence and knowledge as follows:
"I would like to focus our lesson on the wonders of the world."
Miracles and miracles, as far as is known, have no explanation and no solution.
Upon hearing the opening statement, seven wonders of the world immediately came to Rakfat's mind, among them the pyramids in Egypt, and to her question the science teacher explained that the pyramids are not only not in the possession of a miracle at all, but moreover, it is impossible for such a stable structure whose base is so wide and whose base is so narrow - It will not be maintained in its stability and there is no wonder in that.
"And I will add," explained the scientific teacher, "if any structure from the past had collapsed or collapsed, we would have had no record of it anyway, and there certainly would have been no physical commemoration of it and its fate would have been to disappear from consciousness; Only the buildings that, in one way or another, for some reason, remained intact - exist today, and therefore we should not be surprised at the ancient buildings that we see these days; And do you know how many other buildings are no longer there?"
"But," asked Rakfat, "does the wonder lie in the difficulty of building the pyramids?"
"It is a mistake to think so," the science teacher marveled in his explanation, "today scientists already know that the pyramids were built gradually by preparing earthen embankments in the form of an inclined plane, the top of which changed according to the needs of the construction, and in a situation where manpower and human life are of no importance, as it was then. From the engineering point of view, this is a completely simple construction, completely unsophisticated, and as mentioned also an inherently stable structure that there is no wonder that it did not collapse and was not destroyed with the passage of time."
"So what are the wonders of the world?"
"If you had continued with your pointless questions about pyramids and the like, I would have had to answer that we will talk about the wonders in the next lesson, but how good and wise of you that you came to your senses on time, and we still have enough time left to discuss the real wonders. And the first of them happened to me this morning, when I slept completely refreshed - even though I went to bed last night I was hopelessly tired."
"Then what's the wonder, you slept..." - Rakfat commented again, and to this puzzling question the science teacher waited to answer: "And because I did something in my sleep? After all, I didn't eat anything, I didn't receive energy injections, I was simply completely tolerable - and in this situation, it is puzzling to me to the point of defining it as a miracle of miracles, where did the sensations in my head go and where did the fatigue that afflicted me go? We are used to accepting this as a matter of course, but it amazes me every morning.
And, who knows what Newton's second law is? I tell you: the force [F] is equal to the product of the mass [m] by the acceleration [a], and the formula is of course F=ma. In other words, as the acceleration increases, the acting force increases in the same ratio; Acceleration increases 2 times, the force will increase exactly 2 times. Acceleration increases 3.5 times, the acting force will also increase 3.5 times. And that there is no miracle in this, in the fact that the force increases in discussion in direct proportion to the increase in acceleration, and not to the 1.2322 or 0.9826 power, for example? From where does the force derive its power to discover and prefer with incredible naturalness the power 1 for its growth according to the growth of acceleration?
And in another matter: Einstein's formula for the conversion of matter into energy E=Mc2 is known according to which the energy E is directly proportional to the square of the speed of light c. And the formula for the force of attraction between two bodies is known, according to which the force of attraction is inversely proportional to the square of the distance between these two bodies, which is remarkably consistent with Coulomb's formula regarding the electric force of attraction between two electrically charged bodies [charges], according to which this force is inversely proportional to the square of the distance between Both charges.
And I wonder and my heart is full of wonder, wonder and wonder, where does this uniformity of the 2nd power come from - to say - why energy is released from matter exactly according to a quadratic ratio, why as bodies with masses move away from each other, the force of attraction between them weakens with masterly precision in direct proportion to their distance to the 2nd power, and not to the distance between them To the power of 1.94, and why is it that as two charges move further apart, the electric force of attraction between them weakens in exactly the opposite proportion to the square of the distance between them, and not to the distance to the power of 2.65 or any other number?...”
These difficulties remain [as promised at the beginning of things] unanswered...
