Today, March 14, International Pie Day is celebrated. The date 3.14 according to the American notation system, constitutes the first three digits of the mathematical constant pi. On this day, mathematicians, physicists and just geeks around the world usually gather for pie celebrations during which they sing holiday songs, compete among themselves in memorizing the digits of the mathematical constant and of course eat pie. And it's also Einstein's birthday.

Pi is an irrational number that represents the constant ratio between the circumference of a circle and its diameter. This ratio, which was already known in Babylon, ancient Egypt and was even mentioned in the Bible, was calculated for the first time with an accuracy of more than 2 places after the decimal point by Archimedes in the 3rd century BC. According to Archimedes' method, the circumference of a circle must be smaller than the perimeter of a polygon that blocks it and larger than the perimeter of a polygon that is blocked by it. Archimedes started with a hexagon and increased the number of sides until he reached a polygon with 96 sides.

The original Pi Man, the inventor of Pi Day, Larry Shaw, is a physicist at the Exploratorium Science Museum in San Francisco. In 1987, Shaw used to think a lot about the idea of ​​rotating to another dimension. To explain the change of time and place, Shao used the improbability engine metaphor of the "Golden Core" spaceship from the book "The Hitchhiker's Guide to the Galaxy" by Douglas Adams. It turns out that the idea of ​​spinning into another dimension is exactly what Pai describes. Pi represents the conversion of the circle from one linear dimension to two or three dimensions. So for Shaw, pi was more than just a mathematical constant and that's why he and his colleagues decided to hold Pi Day at the museum.

Pie in the Bible

In the book of 3 Kings (XNUMX, XNUMX) the construction of King Solomon's temple is described: "And he made the sea solid ten cubits from its lip to its lip round about and five cubits its height and a line thirty cubits round it." The sea is solid - meaning a large, round basin in which the priests washed their hands for purification. In this source the number pi is rounded to XNUMX.

March 14, besides being International Pie Day, also marks Albert Einstein's birthday. In Israel, this day is defined as Science Day, in which special attention is paid to science and its advancement.

Pi Day is usually celebrated at 1:59 because 159 are the next digits of the mathematical constant - 3.14159.

  1. Please familiarize yourself with new geometry

    There are two types of pie, mamartsi and round. (mmarts = multi-sided elaborate polygon)

    The perimeter of the MRC is the cumulative length of identical straight segments, which are the sides of the MRC.
    The pie of a square expresses the ratio between the circumference of a square, along a straight diameter of a blocking circle.
    Mathematics is able to calculate the pi from the Mertz, because it is straight line segments.
    Its exact value is unknown, but it is between 3.1415927 and 3.1415928
    The calculated result of a pie from maretz, is suitable for all large or small maretz.

    Circular pie expresses the ratio between the circumference of a circle and its diameter. The circumference of a circle is a closed circular line of its own length, and its diameter is a straight line of its own length.
    Mathematics has never been able to calculate the value of a circular pie, because the mathematical calculation is only suitable for straight line segments.

    Everything that mathematics has been able to achieve regarding a circular pie, is based on the knowledge that the length of a closed circular line that blocks a square is slightly greater than the cumulative length of the sides of the square. That's why ....a circular pie (will always be a little bigger) than a marshmallow pie.

    It is emphasized that mathematics, which boasts of its extreme precision, has never been able to find a formula that allows a transition from a square pie to a circular pie. To find such a formula, one must first find a formula that allows a transition from the length of a string to the length of its circular arc.

    Such a formula requires the use of an actual length of string, such as 1 cm
    A string 1 cm long may have many circular arcs of different lengths.
    The longest arc will appear in a circle that is 1 cm in diameter, and the shortest arc that is 1 cm in length will appear in a circle that is infinite mm in diameter.

    And since mathematics does not have a formula for going from the actual length of a string to the length of a circular arc
    It was necessary to state that mathematics does not have a passing formula from the length of the largest chord of a circle, to the length of the circular arc of this chord. (Therefore, there is no conversion formula between the diameter of a circle and its circumference)

    And the result is amazing
    Mathematics has never been able to calculate the value of a circular pie.
    Mathematics has never claimed to be incapable of calculating circular pie.
    No mathematician has ever stood up and declared: I am unable to calculate circular pie.
    And yet, for 2000 years, mathematics has used the result of a pie from a square suitable for all squares, as if it were a circular pie suitable for all circles,

    Amazingly and against all conventional wisdom, a new way to Pai was opened from Martsi.
    This is a physical way, which includes a very precise mechanical measurement.

    The circumference experiment revealed that each circle has a unique value of circular pie.
    This experiment also revealed the area of ​​circular pie change between 3.1416 and 3.164
    The guiding rule: the smaller the circle, the greater its circular pie value

    A. Asbar 14/3/2021

  2. For reasons of convenience, those involved in geometry decided that a single number allows the transition from the length of the diameter of each circle to the length of its circumference. This number was given a name and it is Pi.
    Pie should allow the transition from a diameter of 1 mm along the circumference
    Pie should allow the transition from a diameter of 1 meter along the perimeter.
    Pie should allow the transition from a diameter of 0.01 mm, to the length of the circumference
    Pai should allow the transition from a diameter of 1000 meters, along the perimeter
    After this arbitrary decision, dealing with circles became very simple, and geometricians were left with one goal, and that was to calculate the value of this single number.

    This arbitrary decision is not correct, and it has been handed down from generation to generation since the days of Archimedes to the present day.
    This arbitrary decision is accepted by today's academia, and the following article tries to convince the academy
    Find a dignified way to withdraw from the arbitrary decision

  3. Michael, you continue with a useless personal attack and time and time again you conjure up your baseless nonsense. I request such behavior - at the Ramallah Institute of Science.

  4. Tal:
    It can be described as such.
    My computer was portable, so it is clear why it was stolen.
    The alarm went off but the thieves managed to escape before the ranger arrived.
    Other people's computers are the ones I bought for them anyway.
    In any case, I make sure not to keep Shabbat.
    Many times I also comment here but some of my other activities are also criminal as far as religion is concerned.

  5. Michael, I understand that only your computer was stolen out of all the five computers in the house, lucky snake
    And since then every week you observe Shabbat
    and engages in other activities of Talmud Torah, and prayers in the synagogue.
    And in the middle of the week he is arguing on other people's computers.

  6. By the way: what you don't think I understood myself. There was no need to mention it.

  7. My name is anonymous:
    I said in advance that the expression you used "the curved circumference of the river" is not clear, and until this moment you have not clarified what it is about. Therefore it can be said that I do not exactly understand your words.
    I actually understand what is said in the article very well.
    You are just engaging in a personal attack instead of the matter.
    Do you have any proof of your words or did you receive them through communication with the flying spaghetti monster?
    Would you mind explaining what you call "curved circumference of a river"?
    The truth is that you are not worth the effort of arguing, but in the meantime I enjoy watching you humiliate yourself in your attempt to humiliate others.

  8. Michael, I don't think, I know.
    Your error is due to the fact that you do not understand the above article and cannot see how my words do not contradict the scriptures. Read again.

  9. friends You forgot to mention the famous American pie.
    Is she not mentioned in the Bible?
    In any case, also regarding the pie cake, if it is round then the ratio between its gauge (diameter) and its circumference is...pie.
    Does square pie come out anywhere? And maybe Pai2x?

  10. fresh:
    It happens that people's memory goes wrong.
    I wish you a full recovery.

  11. My name:
    It matters what you want.
    I guess you also claim that what is written in the article written by people who measured the rivers is also wrong.
    Keep it up! Don't let the facts confuse you!

  12. praise,

    In the Bible there is an even more accurate calculation for pi:

    Close value in your book: 3

    Proverbs 1059, XNUMX: For the dead are many, and objects are all slaying = XNUMX
    Proverbs 1109, XNUMX: For there is no peace for ever, nor a vow for generation = XNUMX

    (Approximate value of pi) multiplied by (Mishli 3.141643, XNUMX in gematria) divided by (Mishli XNUMX, XNUMX in gematria) = XNUMX

    Exact value of pi 99.9984%

    Our sages knew everything even before today's science

    And if you want, you can find an even more accurate value in Alice in Wonderland...

  13. point:
    Since my house was broken into and my laptop was stolen, I decided not to buy a new one because I no longer need to walk around with the computer.
    I also decided that there is no need to buy a new computer since each of the other four members of the house has a computer and they are most of the time at work so I can work on their computers.
    On weekends the situation changes because everyone is at home and uses the computer more and I try to dedicate the time to other activities.

  14. A more appropriate explanation for the spelling of the words "Vokoh"/"Voko" is found in Maimon Cohen's book, "The Spelling and Words in the Bible", page 85.

    An explanation based on gematria has no hold. One may ask why the words "line"/"koa" are used in the calculation, and not the words "koo"/"vakoa" which are the ones that appear in the verses. Beyond that, the gematria method is Greek in origin, as evidenced by the name, which means "(the letter) gamma (equals) fresh (=three)".

    The inhabitants of Judah and Israel during the First Temple period did not have any need for the gematria method as they developed a unique method for indicating numbers based on the Egyptian hieratic script. In this method there were special digits not only for units but also for tens and hundreds. This method is used in inscriptions next to the grade in words. An example of a table of numbers using this method can be seen in Ostracon 6 Barnea Temple (the following note is taken from Raz Kalter's book on the subject):
    http://books.google.com/books?id=sca3IHGosFoC&pg=PA115

    It is possible that this method can be used to explain the approximation found in the Bible. The scribe who was aware of the more accurate approximation (during the second millennium BC they already knew pi to one decimal place in Babylon and Egypt, i.e. 3.12 or 3.16), may have simply recorded the measurement of each factor in one digit only (10 and 30) and not 2 (31 required two digits). But this is only a hypothesis, and the explanation that it is simply an approximation of the writer and/or the measurement is the most plausible explanation.

    An example of a similar ritual basin can be seen in the temple in Arad from the First Temple period:
    http://mikranet.cet.ac.il/pages/item.asp?item=11397

    In any case, what is written in Tanach does show that at that time they knew an approximation of the ratio between the circumference of the circle and its diameter.

  15. alas I tried to prevent the discussion that developed here, and probably caused its creation.

    As a matter of fact, the information found or not found in the Bible is meaningless, as is any prophecy that is revealed in hindsight. I prefer Archimedes' method any day, who said exactly what he was trying to achieve and how he was doing it, over the Bible's approach, she is:
    1) Can only be identified if we know exactly what we are looking for and what the value of pie we are "aiming" for, and certainly nowhere does it mention the concept of pie, or even hint that the ratio between the circumference of the circle and its diameter may be constant.
    2) Does not explain where the "correction" came from, but only where the basic rough figure came from (of 3, which was probably obtained through inaccurate measurement).
    3) (and this is the worst) does not offer any way to achieve a *better* approximation. Based on Archimedes' method, they managed (in the 16th century) to give an impressive approximation of pi with an accuracy of thirty-five digits. The biblical method could not be used for anything like that - indeed, it is no wonder that no one mentions it anywhere in a serious mathematical context.

    In conclusion, even if indeed this entire stunt was the exact intention of the writer of the Bible, it is not interesting and certainly not impressive, because the bottom line is that it is not an approximation - if indeed God was involved in the matter, one could expect a better approximation . What could be the "clue" here? "Look, I also know how to calculate Pi to the exact... oh, not something, and without saying how"?

    It seems to me that it is better to leave the whole thing as an amusing curiosity, because when you start hinting that it has a meaning beyond that, the business stops being amusing.

  16. praise,

    I am not trying to mock the theory you are presenting, but I am presenting the current facts. If they are ridiculed, it is only from their nature. The theory you bring is very big, and to substantiate it you need to refer to the set of facts.

    What I showed you in the gematria calculations I brought, is that almost every word can be interpreted in dozens of different meanings according to the laws of gematria. That being the case, if proof of almost any idea can be found using geometry, what's the point of relying on it?

    Moreover, how do we know whether the biblical writers really intended to use gematria in a certain word or not?

    I'm still waiting for an answer that doesn't come off personally, and that will clarify how you can differentiate between a cipher that was intentionally hidden in the Bible, and the sheer randomness of the gematria. If you cannot find such an answer, perhaps you should think to yourself whether you are not biased in advance, and whether others are infected with 'antagonism to the Jewish origin', etc.

  17. praise. I didn't think for a moment that you were going in this direction...
    I said it was beautiful. Because it's entertaining... and nothing else.
    I see you take it seriously.

  18. Praise Stern:
    Indeed, the way you propose to interpret the Bible is extremely interesting.
    It's also interesting why the person who wrote it also didn't know how to write things in a simple way but needed such a crazy exercise like the one you came up with.
    But you know what? Leave for a moment the delusional bickering about pie and explain to me why the Torah claims that the Euphrates and the Tigris come from the same source.
    Do you also have an explanation in gematria?
    Or will you tell us like someone who tried to explain the funny fallacy of raising the migration of the rabbit that the vast distance between the sources of the two rivers appeared to man that God raised him to the height of his seat as one point and God simply did not want the facts to confuse him?

  19. Roy

    A. You are trying to mock a theory that I supposedly presented, according to which *every* word written in the Bible represents something in gematria. I did not try to make such a claim, therefore your attempts to bring examples that are not of the kind of claim and to laugh at the particular case I brought are nothing but stand-up comedy.
    Therefore the answer I am replying is not intended for you - the clown, but for other viewers of this discussion.

    B. As a matter of fact - in the sources of Judaism, there is sometimes the use of geometry or other methods of encryption, such as the OT of the Bash and the like, to allude to topics that for one reason or another they did not want to write about explicitly.

    Even those who consider themselves a rational person, neither a believer in God nor a mystic, can consider the possibility that someone from the Jewish sources had a certain mathematical knowledge that allowed him to calculate the pi with a level of accuracy a little higher than Archimedes and encrypt this knowledge in a way that was acceptable to writers of records at the time.

    Or does the contempt for everything related to a Jewish origin arouse antagonism to the point of being unable to objectively deal with a hypothesis that someone else puts forward. God knows solutions.

    good week

  20. praise,

    I am not the subject of the discussion, but your theory about the pie.

    Just as there is evidence that supports the idea that gematria in the Bible describes the pie, so there is also contradictory evidence (ko-koh = molecule, hypnotism and semi-vibrator).

    If you want to prove that gematria describes the pie, you must also explain why certain interpretations are inconsistent with reality.

    good week,

    Roy.

    post Scriptum.

    In the explanation you will present, I also expect to see an answer to why God is also Soviet, green is also light purple and 'God' is both turtle and inedible.

  21. Mr. Cesena, so I understand that The Hitchhiker's Guide to the Galaxy is your rational scientific basis.

    Shame on you!

  22. supplement facts:

    Ku-ku is also the croaking sound of a frog - an unclean animal - and when done by a person, it implies disdain and contempt for the idea.

    Ku-ku also corresponds in geometry to 'molecule' - and Pi was never a molecule.

    Ku-ku corresponds in geometry to 'hypnotism' as well. Has the number Pi been used to hypnotize people in the past?

    A line in geometry, corresponds to half a 'vibrator', his name is happy.

    praise,

    Science relies on explaining existing facts. If the geometry is a scientific support for your hypothesis, I would appreciate it if you could explain to me how the croaking of the frog, hypnotism, the molecule and the vibrator halves are related to Pi.

    Thanks,

    Roy.

  23. my father (9)

    Why should you be so unsettled by the possibility that the writer of the Book of Kings (Jeremiah and his faction - according to the Talmud - Baba Batra XNUMX: ) knew a little more than Archimedes about the circumference of the circle? What is the fear? Someone might repent because of this?

    Won't you let the invoice facts confuse you?

    It is a clear fact that the phrase ko-koh is a synonym for perimeter. Second fact - ie - spelling. Third fact - the calculation is correct (I checked again!). Fourth fact - 3.1415 is more accurate than Archimedes' 3.14.

    Admittedly - this is not scientific proof that the writer of the words meant this, but it justifies being certain. It seems to me that to state in such a ruling - that there is no hint and no meaning is arrogance without scientific integrity!

  24. Walla
    So that's how you make the smiley.
    I thought I was just making smileys with brackets and dots, and it made me a real smiley.

  25. third.
    why are you sad?
    It's not an argument, it's a conversation about the relationship between science and the Bible. 🙂

  26. It's quite sad that on the day dedicated to science, on a website that dedicates every article to science, there is a debate about gematria and references to Pi in the Bible.
    Just as the Bible mentions an atomic bomb (after all, how else were Sodom and Gomorrah destroyed?) and just as there is a mention of the laser and other scientific topics, so is the "accurate" mention of the pie.

    No bears or forest.

  27. sure you can
    But it is not at all suspicious that in the same verse there is reading and spelling and a mention of the sea and an approximation of 3?

  28. With geometry you can prove anything you want, and who is responsible for the fact that the writers of the Bible did the arithmetic exercise you describe?
    And as for your answer - there is no clue and therefore no meaning either.

  29. Yael

    You quoted the biblical source and note a nice and interesting thing:

    The circumference of the circle is called a "line" but in the quoted verse it appears in the initials "and line" and in the spelling "and line"

    Is there a meaning to the spelling and spelling?

    Line in geometry - 106
    Line - in geometry - 111
    The approximate described pie = 3

    111/106 * 3 = 3.1415

    Precision of 4 digits after the point.

    Does this have any meaning in connection with any hint given in Kriti and Kabit? The reader will judge!

    (Speaking on behalf of Omram - Prof. Ali Mertzbach - from Bar Ilan University)

  30. Gadi Alexandrovich'
    The outer circumference of the circular cauldron below the rim of the decoration.
    That is, the outer diameter was 30 per pie. The internal can be calculated by reducing the thickness of the copper as mentioned there. And according to this the volume etc.

  31. Gadi Alexandrovich'
    The ratio mentioned there is accurate because the mentioned circumference is the outer circumference, while the apparent diameter indicates the distance from the edges of the boiler that opened upwards in a flower-like decoration as indicated there. All the measurements there are relative and the size of the boiler can be deduced through calculations according to its total volume as indicated there.

  32. Agree with Gadi Alexandrovich
    make a circle And then measure approximately.
    And came to mark disgust.

  33. You don't need to go so far as to say that a numerical description of something round that appears in the Bible is a mention of pi; and it is certainly not an interesting mention of it, because only a trivial approximation can be deduced from it, which probably results from a rough and rounded measurement. The scripture also did not attempt to describe pi at any level of precision , so this whole business (which, unfortunately, some use to show that the Bible is "wrong", and others use delusional interpretations to show that the Bible is "right") is irrelevant.

  34. someone,

    In the third paragraph from the end, the source from the Bible is quoted. They measured the ratio between the circumference of the pelvis and its diameter and roughly came to the conclusion that it is 3.

    Birch,
    About 130.

  35. They researched and found that when measuring the extent of streams and rivers in the world - and this is true for all streams - the distance from the beginning of the river to its end as the crow flies is in constant proportion to its curved circumference and is roughly equal to a very large pie.
    This world is funny...
