On Sunday, June 19.6.2022, XNUMX, a ceremony was held for the winners of the National Mathematics Olympiad for elementary and middle schools, at the Weizmann Institute of Science.
The Mathematics Olympiad for young people is organized by the Young Mathematician Organization, in collaboration with the Weizmann Institute of Science, and is intended for students in grades XNUMX-XNUMX and is free of charge in order to promote mathematical education in Israel and to provide a response to elementary and middle school students who want to learn mathematics at a high level already at a young age.
The "Young Mathematician" organization was established in 2017 by a group of mathematicians and teachers. The organization delivers several educational programs at different levels, including courses, training camps, mathematical Olympiads, and more.
Out of 1500 contestants in the first stage of the Olympiad, about 600 students from all over the country advanced to the second stage, 337 outstanding students advanced to the final itself, and after weighting the scores - the list of winners of the competition was published.
David Kravitz from XNUMXth grade from Kfar Saba, who studies at Ofira Navon, won first place for his age group and he tells us: "Mathematics for me is not just theory - it is practice for life. I studied hard throughout the year and invested a lot of time in studies. I hope that I will be able to take part in every mathematical competition that will be held in Israel and in the world and my dream is that I will know the field really well and will be able to invent new things that will benefit many people. The great mathematicians added many new things to the field.'
We met you Harel Hamo from Kiryat Bialik, from the Rakfat school who received a certificate for the age group of the third grade: "I started studying mathematics as long as I can remember! My father would give me math exercises, verbal questions and riddles. Mathematics is an important subject, and it is important to me to be good at it. Sometimes there are very interesting questions whose answers are not simple and you have to think about them carefully to find the answer.'
Ili and Eliran Shilon Rahav, the brothers from Moshav Maor, prove that excellence runs in the family, Aili won first place in the third grade age group
Valiran won third place in the XNUMXth grade age group! And they weren't satisfied with this win either, Eliran, just a month ago won the title of world chess champion, who is only 10 years old.
Below is the list of winners (partially) - first places in each age group XNUMX-XNUMX:
- Nega Aharoni, XNUMXrd grade, Tel Aviv, Ehvat Zion school
- Ili Shilon Rahav, XNUMXrd grade, Moshav Maor, Nitzani Reot school
- Peleg Shalom Lev Ari, XNUMXth grade, Petah Tikva, Ein Ganim school
- Aviv Wald, XNUMXth grade, Petah Tikva, Ein Ganim school
- David Kravitz, XNUMXth grade, Kfar Saba, Ofira Navon school
- Ron Weinstein, XNUMXth grade, Yakneam Ilit, the division for innovation and entrepreneurship
- Avinaam Atias, XNUMXth grade, Kiryat Ata, High School for Sciences and Arts
- Yotam Bodnik, XNUMXth grade, Rehovot, De Shalit School, Division XNUMX
among the leading cities in winners And in the winners you can see Tel Aviv with 15 winners in the Olympics, followed by Rehovot with 11 winners and Jerusalem with an impressive representation of 9 winners. The city of Ramat Gan with 7 winners and Haifa and Petah Tikva with 6.
Maria Greenglaz, head of the Young Mathematician organization and organizer of the Olympiad: "This year we are holding the Youth Olympics for the fifth time. For many students this is the main event of the year, a real mathematical celebration and an opportunity to meet other children with similar interests. We are happy to excite children with challenging and non-standard mathematics, to give them questions that will require deep thought. And another goal of ours is to locate the strongest students in the country already at this age, and to promote them as much as possible - to the Israel (adult) mathematics team, to academic studies while still in school, and in the end, hopefully - to engaging in mathematics later as a profession.''
Math Olympiads are a tradition that began at the end of the 19th century in Eastern Europe, and aim to encourage school students to become interested in advanced mathematics at an early age. As of today, Olympiads all over the world are a spearhead for the education of future generations of mathematicians.

Fermat's last theorem
And the first sentence of Asbar.
Fermat's last theorem belongs to mathematics, and it presents a claim of the type "no"
The claim says that in reality there are no equations of this type aaa + bbab = gggg
Esbar's first sentence also presents a claim of the "no" type, but it belongs to geometry.
There are no two circles in reality,
that have the same pi number
Ferma and Asbar present claims of the "no" type
It is impossible to prove a non-existent claim and it must be accepted upon its appearance as a true claim - which may be disproved tomorrow
If a person suddenly appears with 3 numbers a b c
which fulfill the equation aaa + bbb = gggg
So Ferma's claim will be disproved, and there is such an equation.
To date no such person has appeared -
And maybe he will come.
Amazingly, many mathematicians tried to prove the claim for many years, even though there is no possibility of proving a claim of the "no" type.
It is possible to prove that there is something
But it is impossible to prove that there is nothing.
so,
You have to immediately accept Fermat's claim as a true one, and then you have to wait patiently until a mathematician appears with the three numbers to disprove it.
And if such a rebuttal does not come,
The claim will continue to be accepted as a valid claim.
So why did mathematicians continue for many years to try to prove that there is no such equation, when they knew that it was impossible to prove a claim of the type no
Apparently not everyone believed that it was impossible to prove a claim of the "no" type, and there were mathematicians who thought that it was possible to prove a claim of the no type,
These mathematicians were really looking for the three numbers A B C, which are supposed to satisfy the equation Aaa + Bbab = gggg
But this equation has never been found, and no mathematician has ever appeared with three numbers
A B C, which fulfill the equation
Aaa + babb = ggg.
And yet, there have always been mathematicians who continued to search for this equation.
Mathematicians have always claimed that reason, logic, and common sense are a candle to their feet, and therefore they should have stopped trying to prove a claim of no kind.
But amazingly they did not stop, and a well-known mathematician spent many years to prove that Ferma was right, and in reality there are no 3 numbers A B C that satisfy the equation Aaa + Bbab = Ggg
This mathematician also received an award of recognition and appreciation from the community of mathematicians in the world,
He would have deserved a greater reward, if he had published that a claim of the "no" type is immediately accepted as true upon its appearance, and therefore there is no need to try to prove it - and there is no ability to prove it.
But the mathematicians probably would not have changed their ways, and would have continued to try to prove claims of the "no" type or reject them completely.
This is what happened with a new claim of the "no" type that belongs to Asbar.
This claim is presented as Asbar's first theorem, and it belongs to geometry and not to mathematics.
There are "no" two circles in reality,
that have the same pi number
The mathematicians, who trust reason, logic and common sense, ignored this obvious claim, which is of the "nothing" type, and instead of accepting it immediately and waiting for its refutation, they simply stated that it is so wrong, and in fact, everyone has
The circles in reality, a single pi number.
And the mathematicians went on and stated just like that, that the size of the circles is of no importance, and they all have a single pi number.
And how did the mathematicians know that all circles in reality have a single pi number?
they didn't know
And they decided just like that for reasons of convenience - because all the circles in reality - from the smallest to the biggest - have a single pi number.
Mathematicians knew that the pi number of a circle is obtained from the number of millimeters of length of a closed circular line (circumference of the circle)
Divide by a number of millimeters length of a straight line, which is (the diameter line of the circle)
But the mathematicians didn't know how to get these millimeter length numbers, because they don't deal with measurements.
That's why they presented an estimate close to reality, of a single pi number a little larger than 3.14
The approach of the mathematicians to Asbar's first claim, which is a claim of the "no" type, was completely illogical.
Instead of accepting the claim and waiting for its refutation, they came up with a cryptic unfounded claim, and it says that all the circuits that exist in reality, have a single pi number.
There is no doubt that the claim that all circles have a single pi number, whose value is a little more than 3.14 is a big nonsense that lacks any foundation and understanding.
To prove that the mathematicians are wrong with the idea of a single pi number that fits all circles, a very precise practical measurement, which is not a measurement of lengths, was conducted by Asbar.
This measurement proved beyond any doubt,
that the ratio of the diameters of two circles (is not equal) to the ratio of the circumferences of the circles.
This proof was obtained from an innovative mechanical experiment unknown to science, which was named the scope experiment.
The scope experiment proved that the pi number of a circle with a diameter of 2 mm is slightly greater than the pi number of a circle with a diameter of 120 mm.
The result of a somewhat larger one was enough to produce a tremendous revolution in geometry, which had been frozen for many years, since the days of ancient Greece.
The result of the scope experiment allows us to declare the emergence of a new geometry of circles, which is
The geometry of closed circular lines.
A circle is a literary name - and a closed circular line is a precise geometric name, indicating the length of the closed circular line, which creates the name circle.
If mathematics should have learned anything from Fermat, it is the idea that it is impossible to prove a proposition of the type none and must be accepted as it is.
Fermat claimed that in reality there are no 3 numbers a b c
which fulfill the equation aaa + bbbb = gggg
And Asbar claimed that there are not two circles in reality,
that have the same pi number
This claim developed into a new geometry of circles that the world of science won over
The claims of the "no" type shocked mathematics, which was considered the queen of sciences, and it lost its royal crown.
The mathematicians made a mistake when they tried to prove a claim of the "nothing" type and the mathematical logic was gone with the wind.
Mathematicians supposedly proved the idea of a single pi number, and taught incorrect geometry for hundreds of years.
The mathematicians rejected the scope experiment outright,
And they did not accept the rule
"The practical experiment is the final arbiter in science"
Mathematicians supposedly invented a new type of exact calculus, differential and integral calculus.
This calculation is not accurate, and it brought to the students the phenomenon known as "math anxiety"
The mathematics that operated in the geometric field of round and curved lines was imprecise
To say the least.
The mathematics that operated in the geometric field of straight lines was also not perfect, and was based on the Pythagorean theorem.
On the other hand, the mathematics that dealt with counting one, two, three, was precise and perfect, and this is the language of computers.

The children of the suburbs are busy with the Olympics for chopping wood and drawing water
In response to Hadassah's words: It seems that only two schools from the list are schools with gifted classes. Let's not talk about it, usually students reach such achievements not thanks to a school.
Unfortunately, it seems that all the winners are gifted people who were lucky enough to study in gifted classes (according to the list of schools you published), and not gifted people who were forced to attend gifted enrichment centers. There is no equal opportunity in this country for everyone.
