# Compared with Archimedes’ pi, where is Newton’s gravitational constant G wrong? Compared with Archimedes’ pi, where is Newton’s gravitational constant G wrong?

The universal gravitational constant G is the number that can not be separated from the mechanical calculation. It is the same as the common pi of the mathematical calculation. It is understood that the calculation principle of the pi is compared with the calculation principle of the universal gravitational constant. For the constant G and π, a principle is more reasonable, more accurate and more scientific. A guess based on the blindness of the scientific value is based on the calculation of the unsuccessful calculation. The calculation of the earth by a small shot is more and more suspended. The same two key constant values ​​for the algorithm are actually very different. pi”π” Figure 1 pi”π” Figure 2

Because The circular shape is different from the special structure of the rectangular square triangular trapezoid, and it is impossible to calculate the circular area and volume before the pi is born.

The pi (Pi) is the ratio of the perimeter to the diameter of a circle. It is generally represented by the Greek letter π and is a mathematical constant that is ubiquitous in mathematics and physics. π is also equal to the ratio of the area of ​​the circle to the square of the radius. It is a key value for accurately calculating geometric shapes such as circumference length, circle area, and ball volume. In analytics, π can be strictly defined as the smallest positive real number x that satisfies sin x= 0.

The ancient Greek contribution to the pi as the ancient geometric kingdom is particularly prominent. Ancient Greek mathematician Archimedes (287–212 BC) pioneered the theoretical calculation of the approximation of the pi. Archimedes starts from the unit circle, first uses the inscribed regular hexagon to find the lower bound of the pi to 3, and then uses the external regular hexagon and uses the Pythagorean theorem to find that the upper bound of the pi is less than 4. Next, he doubles the number of sides of the inscribed regular hexagon and the external regular hexagon, respectively, and turns them into an inscribed positive 12-sided and an external positive 12-sided, respectively, and then improves the lower and upper bounds of the pi by the Pythagorean theorem. . He gradually doubles the number of sides of the inscribed regular polygon and the circumscribed regular polygon until the inner 96-sided and the outer positive 96 are inscribed. Finally, he finds that the lower and upper bounds of the pi are 223/71 and 22/7, respectively, and take their average value of 3.141851 as an approximation of the pi. Archimedes used the concept of iterative algorithm and numerical approximation on both sides, which is the originator of “computational mathematics”.

The famous mathematician Zu Chongzhi of the Northern and Southern Dynasties further obtained the π value accurate to the 7th position after the decimal point (about the second half of the 5th century), giving an approximate value of 3.1415926 and an excess approximation of 3.1415927, and obtained two approximate points. The value is 355/113 and the ratio is 22/7. His brilliant achievements are at least 1000 years earlier than in Europe. The secret rate was obtained in the West until 1573 by the German Otto. In 1625, it was published in the work of the Dutch engineer Antonius. Europe did not know that it was the first time that Zu Chong knew the secret rate, and called the Antoine. Rate.

The exact value of the pi has been constantly refreshed since its birth. On October 16, 2011, the staff of Iida City, Nagano Prefecture, Japan, used the computer at home to calculate the pi rate to 10 trillion after the decimal point, refreshing the 5 trillion Guinness World Record set by himself in August 2010. . At the age of 56, Mr. Kondo has used his own computer, which has been calculated since October last year and took about a year to set a new record. At the beginning of the 15th century, the Arab mathematician Cassie obtained a precise decimal value of 17 pi, breaking the record of Zu Chongzhi’s nearly a thousand years.

The origin of the pi value is simply to divide a circle into approximations of the pi, calculated from 6, 12, 96 to an infinite number of triangles, centered on the center of the circle, as long as there is super function. The more the number of triangles that are divided by the computer, the more accurate the calculated approximation of the pi. Therefore, the calculation principle of the pi is scientific and reasonable, and it is scientific to stand up to any scientist to the primary school.

After looking at the measurement history of the universal gravitational constant, the so-called universal gravitational constant is a ridiculous scientific legend?

In 1687, Newton discovered the law of universal gravitation, but the value of the gravitational constant G is not even known to Newton. It is said that as long as the mass of two objects is measured, the distance between the two objects is measured, and the gravitation between the objects is measured, and the law of universal gravitation is substituted, the constant can be measured. However, because the mass of ordinary objects is too small, the gravitational force between them cannot be measured, and the mass of the celestial body is too large to measure the mass. Therefore, the law of universal gravitation has been discovered for more than 100 years, and the universal gravitational constant still has no accurate results. This formula cannot be a perfect equation. It was not until more than 100 years later that the British Cavendish used the torsion scale to cleverly measure this constant. The experiment in which the gravitational constant was measured was also called an experiment to measure the weight of the earth. Cavandi’s gravitational constant graph

It should be emphasized that when Newton derived the gravitational relationship of the planet to the sun, it has infiltrated the hypothesis. After measuring the gravitational force between some objects and calculating the gravitational constant G, Henry Cavendish measured the gravitational force between various objects. The result is the same as that calculated by the gravitational law using the gravitational constant G. Therefore, the universality of the gravitational constant becomes the correct testimony of the law of universal gravitation.

This is a model of the Cavendish scale. The main part of this torsion scale is a T-shaped light and strong frame that is hung upside down under a quartz wire. If two equal and opposite forces are applied to the ends of the T-frame, the quartz wire will be twisted at an angle. The greater the force, the greater the angle of twist. Conversely, if the angle at which the T-frame is rotated is measured, the force applied to both ends of the T-frame can be measured. First fix a small ball at each end of the T-shaped frame, and then place a large ball in the vicinity of each small ball. The distance between the two balls can be easily determined. According to the law of universal gravitation, the big ball will exert gravity on the small ball, and the T-shaped frame will be twisted accordingly. As long as the angle of the twist is measured, the magnitude of the gravitation can be measured. Of course, due to the small amount of gravity, this angle of twist will be small. How can we measure this angle? Cavendish put a small mirror on the T-shaped frame, and used a beam of light to shoot into the mirror. The light reflected by the mirror is directed to the distant scale. When the mirror rotates with the T-frame for a small rotation. The spot on the scale will move a lot. In this way, the effect of reducing the size of the small ball is measured by measuring the movement of the spot, and measuring the angle of the T-frame before and after the large ball is placed. Cavendish used this torsion scale to verify Newton’s law of universal gravitation and to determine the value of the gravitational constant G. This value is very close to the value measured in a more scientific way in modern times.

The accepted result is that the G value measured by Cavendish is 6.754×10-11N·m2/kg2. The current recommended standard is G=6.67259×10-11N·m2/kg2, usually G=6.67×10-11N·m2/kg2. On August 30, 2018, the Chinese scientists measured the gravitational constant to determine the most accurate G value so far, and refreshed the “Newton universal gravitational constant” study again.

About Newton’s universal gravitational constant G value, starting from the British scientist Cwen 100 years after Newton’s death Dixu, it is his first study of torsion scales to calculate the G value of Newton’s universal gravitational constant. Comparing the calculation of the pi, Cavendish’s G value of the universal gravitational constant calculated by the torsion scale is unscientific regardless of the value.

Because of the application calculation of this value, everything from the assumptions, inferences, hypotheses, etc. established in Newton is not understood, not known, etc. The scientific principle that does not conform to the law of the law is a wrong law that does not conform to the definition of “law” and “formula” that only conforms to the definition of “error formula”. So Cavendish’s research experiment is close to measuring the unknowns in the unknown with the Newton’s law of universal gravitation that can’t stand the scientific verification, much like playing the rules as an athlete and a referee, and then participating in it, because of the card. Dixon believes in Newton’s law of universal gravitation and conducts a follow-up study on a thing that is not completely scientific, as a 100% accurate science. Therefore, Cavendish’s gravitational constant G value, no matter how much, is difficult to verify its correctness. Sex, so Cavendish’s gravitational constant G value study has a principled error from the beginning. Even if the scientist measures the universal gravitational constant, even if Newton reborn, it is difficult to truly solve the unsolved mystery of Newton’s own conjecture hypothesis. .

Science is not to be false. Compared with the pi, Newton’s universal gravitational constant is wrong. At first, Newton’s fantasy hypothesis is a big mistake, and then the domino effect is wrong. Scientific The law of formulas is not to write fantasy novels, to make fantasy assumptions and delusional inferences? So far, scientists have not really measured the gravitational force between the sun and the moon, and what is the effective scientific evidence of gravity? If it is not gravitational between the moon, the Earth, and the moon that Newton assumed, it is impossible for humans to think that the Earth will be 380,000 kilometers away.

If the universe is scientifically researching gravity, it is only like Mr. Wo Ma’s law of gravity, which conducts research and verification between substances with specific gravity, otherwise it will be tested more. Is it difficult to get effective scientific verification?

The gravitational attraction of gravity is comparable to Archimedes’s pi “π” and Newton’s universal gravitational constant “G”. Do you think that Newton’s universal gravitational constant is not reliable? Is it ridiculous?
