In the process of social development, mathematics, as a cultural phenomenon, has attracted people's attention. In recent years, mathematical culture and its related research have been greatly developed. After confirming that mathematics is a kind of culture, we should further understand the connotation of mathematical culture. I have summarized some materials and related contents about mathematical handwritten newspaper for your reference. I hope you can get help:

Manuscript of Mathematical Culture Festival: The "43200" of deja vu —— Re-exploring the mystery

Although many traditional scholars think that the use of π in pyramids is purely accidental, even they admit the fact that π exists. However, we can seriously accept that the Great Pyramid may be the epitome of the northern hemisphere on a plane, with a ratio of l/43200. Let's look at the relevant figures. According to the latest measurement data collected by satellites, the circumference of the equator of the earth is 24,902.45 miles, and the radius to the North Pole is 34,949.38+0 miles. The circumference of the Great Pyramid is 3023. 16 feet and the height is 48 1.3949 feet. The ratio of the two, after calculation, is very approximate, although not completely not bad. If we consider the expansion of the earth at the equator, our earth is oval rather than round, then the ratio of the two seems to be closer to l/43200.

How close is it? If we divide 24,902.45 miles around the equator by 43,200, we get 0.5764 miles. 1 mile equals 5280 feet. If you multiply 0.5764 by 5280, you will get 3043.39 feet. That is to say, the equator of the earth has shrunk by 43,200 times to 3,043.39 feet. The circumference of the Great Pyramid is 3023. 16 feet. The "error" between them is less than 20 feet, only one percentage point of 1/3. ?

Pyramid builders always work in an extremely accurate way. This mistake should not have happened when the pyramids were built, but because we underestimated the circumference of our earth-only 163 miles. This error may be caused by the incorrect calculation of equatorial bulge. Even if the shape of the earth is a little different from today, what will happen? Next, let's review the radius from the North Pole to the Equator of 3949.38+0 miles. If we reduce it by 43,200 times, the value is 0.09 14 mile, which is 482.59 feet. The height of the Great Pyramid is 48 1.3949 feet, the difference between them is less than 1 foot, and the error rate is less than 1/5 percentage points. Aside from this slight error, the circumference of the Great Pyramid should indeed be l/43200 of the equator.

Similarly, despite the slight difference, the height of the Great Pyramid is equal to the ratio of l/432 00 from the North Pole to the equatorial radius. In other words, in the dark period when western civilization knew nothing about the earth, we can multiply the circumference of the Great Pyramid by 43,200 times to get the circumference of the earth.

What is the possibility of "accident" in all this? Judging by common sense, it should be "very unlikely." Any rational person should be able to see that these figures can only be achieved through very careful calculation and careful planning.

Several key indicators and figures in pyramid design show that the number 43200 is a proof in itself. However, ancient Egyptian scholars never regarded common sense as something that should be used frequently. Therefore, we must further prove that 43200 is not randomly set, but a value deliberately chosen on the basis of wisdom and knowledge. In fact, the number 43200 itself is a proof, because it is not a random number like 4500,47000 or 50500,38800, but a link in a series of numbers, which is related to precession and is closely related to ancient myths all over the world.

As mentioned above, the ratio of the golden pagoda to the earth can be seen from time to time in mythology, sometimes it directly appears as 43,200, but sometimes it becomes 432,43,20 or 432,000. This seems to reflect two amazing facts, which are closely related, as if designed to complement each other.

Graeme thinks. It is amazing enough that the Great Pyramid is the correct epitome of the northern hemisphere of the earth. But what is even more surprising is that the scale ratio chosen by the ancient Egyptians is actually related to mastering the key figures of the precession of the earth. ?

This is because the two ends of the earth's axis revolve and describe an arc forever and fixedly, which causes the equinox position on the ecliptic to move with the radian of a complete constellation every 72 years, every 2 1 degree, every 2 constellations, that is, every 60 degrees, which will take 4320 years.

In different ancient myths, the number 432 related to precession has appeared, which may of course be purely accidental. Judging from a single event, the ratio of the pyramid to the earth is 1: 43200, which may be purely accidental.

When we see such numbers related to precession in two completely different things-ancient myths and buildings, we can't and shouldn't talk about accident rashly. The construction of the Great Pyramid allows us to find 43200 which is also related to precession from the π relationship between perimeter and height, and then infer the size of the northern hemisphere, and finally think of the possibility of scale reduction.

Here we get a new geodesic projection method, which has been scientifically proved to be feasible. In fact, the ancients used a similar method to measure the earth, which is briefly described as follows: The original design of the pyramid was to let each face represent 1/4 of the northern hemisphere, which is 90 degrees of the sphere 1/4. In order to project the sphere 1/4 circle into a triangle correctly, the arc of 1/4, that is, the base must be exactly the same as the base of the triangle. Moreover, the height of the two must be equal. To achieve this goal, the height of the meridian that divides the pyramid into two must be at an oblique angle of π ... Are these wonderful numbers really accidental coincidence? Graham thinks the probability is definitely lower than astronomical figures.

Manuscripts of Mathematical Culture Festival: Some Mathematical Knowledge Related to Astronomy

The ancient Egyptians not only recognized precession, but also had the ability to use myths to tell and spread precession. They know more about the operation of the solar system than any other ancient people and know how to observe astronomical phenomena. If the ancient Egyptians really had such profound astronomical knowledge, they must have attached great importance to it and passed it on from generation to generation, making it one of the important secrets kept by the elite priests in Bohris. These priests will be very secret, and through word of mouth, they will only be awarded to strictly selected descendants of the same family. In case they have to write this profound knowledge into the pyramid scriptures because of the needs of the times, they will deliberately present this knowledge in the form of quotations, fables and so on. Protect their secrets. Is this impossible?

Thousands of years before Copernicus and Galileo were born, the ancient Egyptians used earthquake theory to explain the movement of the solar system. It should be noted that neither the ancient Egyptians nor the Greeks who continued the ancient Egyptian civilization, nor even the Europeans before the Renaissance, have seen such profound astronomical data. In the general survey or geographical survey, the skills of ancient Egyptians reached a level that even modern people could not imagine. However, before the ancient Egyptian civilization was civilized, such profound knowledge had already appeared in the scriptures.

What should be the explanation for this? From a long time ago, Graham Hancock began to believe that Egyptian science can be so developed and sophisticated, which must be related to inheritance. He saw that in the distant past, he once had a high degree of technology to explain this mystery.

The ancient Egyptians had a very convenient concept of Sirius periodic calendar, which they thought was given by God. The period of the ancient Egyptian calendar is 1460, and the period of the solar calendar is 146 1 year. This can further support the above view.

In technical terms, the Sirius cycle is "the cycle in which Sirius rises again in the same place as the sun". Sirius will disappear from the sky in a fixed season and then rise from the eastern sky before the sun rises in the morning. As far as time is concerned, this period-excluding the mantissa of the decimal point-is 365.35 days. The mantissa at the back is very long, only 12 points in the solar calendar.

Surprisingly, among the 2000 stars that can be observed by naked eyes, only one star rises with the sun in a period of 365 days, which is the result of Sirius's "correct movement", the speed of the planet in the universe and the precession movement. At the same time, the ancient Egyptian calendar specifically designated the day when Sirius took off before the sun as New Year's Day. In advance, the ancient Egyptians had calculated the arrival of New Year's Day in Bohris, which was compiled by the pyramid scriptures, and informed all the temples in the upper and lower reaches of the Nile.

Pyramid scripture mentions Sirius as "the name of the New Year". From this, I believe that the Sirius calendar is at least as old as the pyramid texts. One of the most puzzling mysteries is, in such a long time, who can have such superb knowledge and technology to observe and record the cycle between the sun and Sirius, which is quite coincidentally 365.25 days? The French mathematician Swarle Rubitz said that Sirius's period was "a completely unexpected and unexpected celestial phenomenon".

Why Sirius? This is because among countless stars, it is the only star that has moved in the right direction by a corresponding distance. In other words, as early as 4000 years ago, human beings have known this phenomenon. It takes a long time to observe the movement of celestial bodies to find this phenomenon. We have nothing to say about the great scientist who developed this purely accidental phenomenon except admiration.

People can see from the pyramid texts that prehistoric ancient Egyptians have a long tradition of correctly observing stars and making scientific records. Moreover, many numbers that indicate precession in their myths are not only very accurate, but also highly consistent, and they can never be fabricated by accident. Their knowledge heritage in astronomy and mathematics was passed down in this way, and the pyramids were the permanent proof of the level of astronomy, mathematics and architectural knowledge reached by the ancient Egyptians at that time.

Manuscript of Mathematical Culture Festival: From Vent to Orion —— The Discovery of Pofahl

1993, an amazing new discovery was made about ancient Egypt. Rob Pofahl, a Belgian civil engineer who is very interested in astronomical research, found that the sky is closely related to the pyramids in Kisha. It was he who noticed another amazing discovery. 1960, Dr. Alexander Bedway, an ancient Egyptian scientist and architect, and Trinbo, an American astronomer, discovered the vent hole on the south side of the Great Pyramid, which was aimed at the three stars of Orion in the pyramid era from 2600 BC to 2400 BC. This was unexpected by ancient Egyptian experts who only paid attention to the ground and ignored the sky.
