How does a Mathematician’s Brain Differ from Others’ Brains? (Like only mathematician brain differs?)

Like “Give a one-hour education and expect a new theorem in return.”?

The question of how mathematicians think is closely related to the question “How does a musician compose?” 

Similarly, this question is asked to learn how the creative process works.

Those who are interested in computer science or especially artificial intelligence can give the correct answer to this question.

A real mathematician is not interested in finding the answer to this question. He’s just busy doing math. (Who is a Real mathematician again?)

There is no clear way to answer the question of how a mathematician thinks. But we can approach this question as follows; if you watched any chess tournament (like who is watching?), the game’s analysis is shared in detail at the end of the match.

When you examine the analysis, you will see a breaking point in each game. Similarly, mathematicians also experience a breaking point while working on a problem before finding a solution.

Therefore, it is helpful to analyze a few mathematical proofs to answer our question and pinpoint the breaking points.

For example, as we all know, Euclid’s theorem states that there are infinitely many prime numbers.

The proof of this theorem is more beautiful than the theorem itself.

So how did Euclid realize that prime numbers are infinite? Euclid’s approach to the solution is fascinating.

First, Euclid assumed that prime numbers are finite. He then constructed a set where he wrote all the prime numbers (all of them?)and called the elements of the set P = {p1, p2, p3,…, pr}. 
So, by that assumption, any number other than these numbers should not be prime. Then Euclid multiplied all the elements of the set P and added 1 to the product. Then he got a new number and called this number N.

Besides this, Euclid has some excellent math knowledge he has gifted with, such as the Fundamental Theorem of Arithmetic.

For example, he knows that if a number is not prime, it can be broken down into prime factors. 
Thus, when he tried to factorize the number N since N isn’t a prime number, N must be divisible by at least one prime number. 

However, all the primes are here, and they cannot divide it because of the plus 1. For example, 2 and 3 make prime numbers, and 2 x 3 = 6. 2 and 3 can perfectly divide the number 6 but not 7 (6+1). So there is a contradiction here. 
The number N is not in the set of prime numbers, but it is prime. So prime numbers must be infinite.
Proof of Euclid’s Theorem

When we look at the proof, we see that Euclid does something different from the norm. (How so? Most of the proofs use the same venues)

Contrary to what we might think, the idea that prime numbers are finite is not creative. Mathematical logic is already directing us to with a start a proof like that. The truly original idea here is when Euclid threw out the number N. (Did Not get it)

Understanding Euclid: A Simplified Approach to Mathematical Thinking

I remember that my mathematical education has started with numbers. First, my father, then later, my elementary…

Let’s try to prove another theorem.

When the children in an elementary school were very naughty, the teacher wrote a difficult question on the chalkboard to silence all the children. 
The teacher asked the children to add up all the numbers from 1 to 100. 

On that day, the young German boy named Gauss, who would grow up to be one of the greatest mathematicians of the future, was in that class. 

While the teacher thought it would take a long time for the children to solve the question, Gauss resumed talking to his friends again in just a few minutes. 
When Gauss’s teacher asked why he was talking, he said he had already solved the question. 

That day, all the students in that class tried to add all the numbers one by one, but Gauss did something unusual. 

He saw that he would always get 101 if he added a number from the left of the sequence and a number from the right. For example, 1+100, 2+99, 3+98,…, 50+51; it was always 101, and there were 50 of them.

If we look carefully at this method, we will see that this is an observation that even a small child can see. However, it is a fact that not all young children solve this question like that. 

Furthermore, many intelligent people who are much older cannot see this simple solution.

In short, we have many good examples to analyze how a mathematician thinks. Almost every mathematician has been adapting and manipulating theorems and the proofs that have been introduced to them before to find a new idea or solve a problem. But those who are considered geniuses are doing a few extra things.

For example, let’s consider a musician.

He doesn’t have to be Johann Sebastian Bach or Igor Stravinsky. It is enough for him to be an ordinary musician who does his job correctly.

Let’s say our musician goes to the conservatory and studies for four years and completes his master’s and Ph.D. Now, if we ask him to make a composition, can he do it? Of course, he can, but we can’t be sure if he can compose something like Bach’s.

Anyone can learn some things by education or training. A student who studies in the mathematics department for four years will surely learn mathematical thinking. But it is unlikely to be something like “give a one-hour education and expect a new theorem in return.”

Mathematical thinking education is a continuous process. 

Students first take abstract mathematics lessons. Then they learn how to prove that prime numbers are infinite, as in the example above. Then they realize they can also prove another theorem in the same way.

For example, using the same method, you can find infinite “p” prime numbers for p ≡ 3 mod 4.

In short, to be a mathematician, the main thing is adapting smaller, known proofs to larger, unknown proofs. These skills become internalized after adequate practice. (Isn’t that the process of sustained learning and training?)

The level of education received has a significant effect on the formation of the mindset.

For example, when mathematicians and physicists come together and discuss, they can never meet at a common point. While physicists look at a problem from one window, mathematicians view it from a different place. (Not all mathematicians. Many scientific minds have the capacity of using a different perspectives)

For instance, when you mention Lie algebra to mathematicians, they describe the bracket operation directly. (How about describing what is meant by Lie algebra?)

However, when you say it to physicists, they follow the path of the structure constant and do their work accordingly. The approaches to the same problem can be drastically different.

Mathematicians generally have a particular way of thinking, and this state of thinking emerges with homework, questions asked in exams, and textbooks read. Again, this is a very long process. It takes a long time.

So far, I have only talked about how an average mathematician thinks. Here, I find it useful to mention some critical figures when discussing the development of mathematical thinking.

One of these figures is the Indian mathematician Srinivasa Ramanujan, whose life was not very long. His mathematics education was different from the education I mentioned above.

Ramanujan’s college performance, other than in mathematics, was so bad that he was kicked out of the university. 

The only math book Ramanujan read was an arithmetic exercise book that no mathematician would ever read. 

However, Ramanujan was a mathematician who wrote huge math formulas and collected them in a notebook. One day, Ramanujan sent that notebook to the famous English mathematician Godfrey Harold Hardy, a Cambridge professor.

Ramanujan and Hardy at Cambridge | From the movie The Man Who Knew Infinity

Of course, since the hundreds of letters were coming to Hardy from everyone in those days, he didn’t take the message from India very seriously at first.

But then, the formula he saw on one side of the letter caught his attention because it was very similar to a question he was dealing with in those days.

“This man is not a charlatan…”

Later, Hardy and his best friend Littlewood started to study all the formulas Ramanujan sent.

They couldn’t even understand some of the notes. Hardy first used the phrase “This man is not a charlatan” for Ramanujan. When Littlewood asked why, he said in reply, “Because it is not even possible to make up those formulas he wrote. So those formulas must be correct.”

 Hardy invited Ramanujan to England immediately in the reply letter.

Hardy and Littlewood noticed something very awkward when Ramanujan arrived. Although Ramanujan could write infinite sums as equality, he knew nothing about modern mathematics. 

So they asked him to learn modern math and take analysis lessons. But then something more awkward happened. Ramanujan could not understand the common epsilon-delta technique, the basis of abstract thinking. Indeed, this was a very unusual situation for students studying mathematics.

When I close my eyes and go back in time, I see a college student sitting in the back row and looking sad while the…

Ramanujan was a genius, and we could not understand how he thought, unlike Euclid. 

Despite solving infinite sums, he could not understand the most basic analysis technique. Ramanujan did not have the slightest idea of complex analysis, but he could work on zeta functions. So Ramanujan had a different mindset in his mind that only he knew, and one we will never understand.

One day, when Hardy wondered about this situation and asked how he wrote all those formulas, Ramanujan told him that God gave him all the formulas, and he had just written them. 

To me, this was a very reasonable answer because Ramanujan was a math practitioner 24/7, and he often forgot to eat. 
His wife or mother reminded him that Ramanujan had to eat. The few times he did sleep, he continued doing math in his dreams.

Such things happened to me during the finals week when I was a student. Once, I was working so hard on the Calculus exam, and I continued to solve some questions in my dream at night.

In England, Ramanujan met his childhood friend Chandra Mahalanobis. 

Mahalanobis was the founder of a very famous institute called the Indian Statistical Institute at the time. Mahalanobis was a student and a good statistician at Cambridge.

Ramanujan and Mahalanobis were 1st and 2nd in a math contest in India when they were children. Ramanujan was 2nd, and it is said that he cried for days saying that he was the greatest mathematician himself.

One day Mahalanobis asked Ramanujan a question:
"There are between 50 and 500 houses on the street, and all the houses are numbered 1 to n. The sum of the numbers of the houses on the left of a house we choose must be equal to the sum of the numbers of the houses on the right. How many houses like this could he find?"

After some calculation, Mahalanobis found out that the 204th house on a 288-housed-street achieved this equality and shared it with Ramanujan.

As soon as Ramanujan saw the question, he said if there were no other conditions, we could solve it by taking a continuous fraction. This question will later be one of the arguments underlying Ramanujan-Rogers’ identities.

Returning to the topic, as soon as he saw the problem, Ramanujan realized that the solution was related to fractionsAn average mathematician, on the other hand, cannot come to this conclusion so quickly. So the exciting example of Ramanujan is a different perspective on the question of how a mathematician thinks.

Ramanujan has another similar story: the taxi plate case. 
When Ramanujan got very sick and was taken to the hospital, Hardy took a taxi and visited him immediately. 

When the atmosphere was silent for a long time, Hardy said that the number plate of the cab he rode was quite ordinary; 1729. Ramanujan replied, without hesitation, “How come it is not interesting? It is the smallest number that can be collected as two different cubes”.

Gauss and Ramanujan are geniuses who internalized mathematics and numbers to a large degree.

The common point in these types of mathematicians is that they are not afraid of calculating the size of the calculations.

But we should know that great mathematicians also think differently from those we have mentioned so far and we never accept their way of thinking.

Unlike the mathematician Ramanujan, Alexander Grothendieck, who studied mainly algebraic geometry, dealt entirely with abstract mathematics.

Algebraic geometry is generally concerned with roots that reset polynomials.

In algebraic geometry, the mathematician Andre Weil previously had some problems that could not be solved for a long time. 

Pierre Deligne, a student of Grothendieck in the 1970s, proved the Weil conjectures.

Grothendieck was very angry with his student when he used a theory about Ramanujan’s modular forms in his proof. Because he saw that Deligne used one of Ramanujan’s theories in his proof, Grothendieck was considered a trick. 

According to Grothendieck, proof must be simple and nothing extra. That’s why he never liked Deligne’s proof. As can be seen in this example, Ramanujan and Grothendieck were two mathematicians with very different mindsets.

I want to prove another example. According to one theorem, there are irrational a and b numbers such that a to the power of b is a rational number. We can prove this theorem as follows.

Let’s take the number square root of two. We know that the square root of two is irrational. 
Let’s investigate the square root of two to the power of the square root of two. There are two situations. 

It is either rational or irrational. If it is rational, we are done because we immediately pick the numbers a and b as the square root of two, and the case is closed. 
However, if the square root of two to the power of the square root of two is irrational, the square root of two to the power of the square root of two to the power of the square root of two becomes the square root of two square. That will be equal to 2. 
So this makes the result rational. So we encounter a contradiction.

If we take this proof as an example of mathematical thinking, it will be sufficient. However, some mathematicians do not like this method of proof.

Such methods have always been at the root of the conflict between David Hilbert and L. E. J. Brouwer. How a mathematician thinks is an important question, but there are also differences in the way of thinking among mathematicians.

One does not like the other’s way of thinking. Some mathematicians don’t even like the axiom of choice. But we use the axiom of choice when performing function analysis. So we use it even in the most basic things.

Now, we talked about rational mathematical thought and its forms, but there is another layer to it as well.

Mathematics is getting more complicated by the day.

Some proofs can take hundreds of pages. For example, the classification of finite simple groups has proof that fills thousands of pages.

There are even rumors that there was a mistake somewhere that says there should have been a few other groups among the sporadic.

That is why some mathematicians are currently working on whether it is possible to make computer programs that can control the proofs or, better, computer programs that can directly make the proofs.

The same goes for music because of music and mathematics progress in parallel.

Musicians are also dealing with similar things like mathematicians. For example, there are music composers for the computer. There is a specific speed limit for humans, we cannot type eight symbols simultaneously, but you can do anything on the computer.

So there are people who wonder whether we can find a place for the computer in mathematical thinking. That idea raises the question:

Can a computer start doing mathematics on its own? 

Alan Turing is the first to ask this question. As a closing thought, while we examine how a mathematician thinks, we should also start thinking about what a computer can do if it starts thinking like a mathematician in the future.’

A chapter written by late Assad Achkar on Leader Antoun Saadi and the Syria National Social party

Nizam Achkar, June 2022

اليوم ذكرى مرور 36 سنة على وفاة الوالد.

واليوم نبدأ بنشر بعض فصول من مذكراته .

وفهم المرحلة الحالية وكيف نواجه تداعياتها.

1- المراحل التي مرّت بها الأمة والنهضة ، من التبشير والتنظيم الى التنفيذ –

اعلان الزعيم الثورة .

قبل ان نفهم النهضة السورية القومية الاجتماعية فهما” عميقا” شاملا” لا يمكننا ان ندرك النتائج والمعاني البعيدة التي تستهدفها هذه النهضة .

من مفاهيم هذه النهضة الأساسية تنبثق جميع المعاني الكبرى التي تعبر عنها النهضة في صراعها على جميع جبهاتها وفي مختلف ميادينها وصورها وأشكالها وظروفها.

فالنهضة السورية القومية الاجتماعية بحركتها الثورية الفعلية الشاملة في لبنان ، وفي سائر دول البيئة الطبيعية ، وباشعاعها على العالم العربي ،

تكوّن حلقة تاريخية رئيسية في الدورات الحضارية الخلاقة الكبرى التي قامت بها الأمة السورية عبر التاريخ ، من سومر واكاد وبابل الى دمشق الأموية وبغداد العباسية.

وهذه الدورات الرئيسية هي الآتية :

أ) الدورة السورية – الأكادية التي تزعمها سرجون الأول في 2300 قبل المسيح . انهت عصر الدويلات – المدينية الضيقة المتذابحة على قطعة من الأرض وقطيع من الماعز ، وحررت البيئة السورية كلها من هذه العقد الاجتماعية – السياسية الصغيرة فاتحة المجالات الواسعة والطرق البعيدة للنشاط السوري الحضاري ،

وأوصلت ذلك النشاط الى قبرص شاملة جزءا” من البحر السوري،

هذه الحركة الثورية الخلاقة كانت الأولى من نوعها في العالم ، كشفت عن الأفق القومية والانسانية وخلقت انسانا” سوريا” جديدا” ترتاح نفسه وتزدهر حياته في الرحابة ، وتفتح لفكره ولتوقه أبواب الدنيا المغلقة.

ب) الدولة البابلية – الحمورابية وهي التي جددت تلك الدورة الحضارية بعد ان خربها البرابرة ” الغوثيون” وتوجها حمورابي بالانتاج العبقري السوري الجديد وهو الشريعة الأولى في العالم ، القادرة ان تقوي وحدة هذا المجتمع القومي – الانساني الكبير ، وتقيه من بقايا التأويلات التقليدية البالية ، المستمرة من عصر الدويلة – المدينية المنقرض.

وقد استمرت شريعة حمورابي معمولا” بها في سوريا والعالم القديم جميعهه حتى الامبراطورية الرومانية التي غيرت . Beirut was the center for Roman laws الشرائع بمساعدة العناصر السورية اليونانية والمصرية الداخلة في الامبراطورية الرومانية .

ج) الدورة الصورية- الفينيقية التي كانت في مياه المتوسط وشطئانه ما كانت دورة سرجون وحمورابي في البر السوري الكبير ، الشامل في امكانياته الحضارية الانسانية خليج العجم وخليج ايسوس ( اسكندرون) وخليج العقبة ، والبحر الفينيقي الكبير ( المتوسط) .

وفي هذه الدورة البحرية ، الاولى من نوعها في التاريخ ، اعطت سوريا قواعد الحياة البحرية للعالم بعد ان كانت أعطته قواعد الحياة البرية.

ولولا العقلية الأشورية ” السبارتية” التي سيطرت على سوريا لكانت وصلت الرسالة السورية الى العالم على اكمل وجه ، ولكانت قبضت سوريا على مصير العالم بفكر ايجابي ونفسية انسانية محبة.

د) الدورة الرابعة كانت دورة آشور والبابلية الجديدة من أوائل القرن الثالث عشر حتى 539 ق.م.

وهي دورة جبارة تفوقت فيها الأمة السورية عسكريا” وسيادة وتوسعا” حتى شملت امبراطوريتها العالمية قسما” كبيرا” من آسيا الصغرى ومصر وشمالي الجزيرة العربية ،

ولكنها قصرت عن امبراطورية سرجون الأول وحمورابي في النواحي الاجتماعية والقومية والفلسفية والعلمية والروح الانسانية .

فالنفسية الأشورية انغلقت على نفسها في الروح العسكرية المتفوقة وتحجرت في نوع من النظام العسكري الذي تقولبت فيه اسبارته في القرن الثامن ق.م. ذلك الانخلاق القاسي كان غريبا” عن النفسية السورية المنفتحة.

ذلك كان سببا” في تبدد المجهود الفينيقي العالمي ، لأن الدولة الفينيقية المدينية الصغيرة كانت عاجزة عن ان تحمل أعباء الامبراطورية البحرية العالمية التي اسستها ، ولذلك انشقت قرطاضة عن صور- الأم وخسرت المرتكز السوري في صراعها مع روما ، مما أدى الى انهيارها .

ه) والدورة السورية الخامسة هي الدورة المسيحية – الأرامية :

لكي تواجه سوريا الفتوحات النصف – بربرية : الساحقة :

الفرس والمقدونيين والرومان ،

ولكي تعوض عن عدم مواجهتها القوة بالقوة ، الحديد بالحديد والنار بالنار ، انعكفت على نفسها وعادت تسبر أفوار عبقريتها . فكان منها أن اطل المسيح على العالم الذي انتصر فيه المقدونيون الرومان ، واطلق القوى الروحية السورية العزلاء من السيوف والدروع لتخضع للروح جميع قوى المادة ،

وبعد قرون ثلاثة أرغم قسطنطين ، صيانة” للامبراطورية الرومانية، فانتصرت الروح السورية من جديد على عالم المتوسط وجميع العالم القديم .

و) والدورة السورية السادسة هي الدورة العربية – الاسلامية أو الدورة الآرامية –العربية . فالآرامية أسهمت في الدورة المسيحية اذ وقفت في وجه المقدونية – الرومانية التي شائت تسخير المسيحية لمطامعها الاستعمارية كما فعلت ،

بعد قرون ، السلجوقية – العثمانية بتسخير ” الاسلام ” لبربريتها. ثم أسهمت الارامية بالتمهيد لمجيء الرسالة العربية – الاسلامية :

عندما المقدونية – الرومانية المستعمرة ، المجسدة في عبقرية قسطنطين الكبير تمكنت من استغلال المسيحية وتحويلها عن خطها الثوري الاساسي ، وعادت هذه المقدونية – الرومانية تستأنف سيرها الاستعماري في سوريا ومصر وآسيا الصغرى ،

لا يقف في وجهها الا الارامية كلغة وثقافة ، والنسطورية والمونوفيزية كمذهبين سوريين مصارعين ، كان لا بد من حركة انقاذية جديدة .وفي هذه المرحلة الدقيقة الحرجة كانت الآرامية النشيطة ، المصارعة ، قد اتجهت نحو الجزيرة العربية and all the way to China، منبع الساميين وقواهم البشرية الذي لا ينضب .

ز) والدورة السورية الحضارية السابعة هي دورة سعاده ، دورة النهضة السورية القومية الاجتماعية .

وقد كانت هذه النهضة أعمق الدورات السورية وأشملها وأدقها فهما” لمعاني النفس السورية وأوضحها تشخيصا” لهذه المعاني الغنية.

ولسنا في هذا المجال لنوضح رسالة سعاده الاصلاحية في جميع مراحلها وحقولها الاجتماعية والقومية ، والعربية الانسانية ، ذلك يأتي في دراسة مطولة خاصة ،

الا اننا نريد أن نعطي لمحة مختصرة واضحة عن سير هذه النهضة من استشهاد سعاده الى آخر سنة 1961 ، وان نعين ، بصورة خاصة ، المرحلة التي تجتازها النهضة في هذه الظروف .

قلنا سابقا” ، ان اعلان سعاده الثورة القومية الاجتماعية الاولى واستشهاده فداء عن الأمة ، يعني بوضوح لا يقبل التأويل دخول النهضة السورية القومية الاجتماعية مراحل التنفيذ والتحقيق ، مع المثابرة الدائمة طبعا” على التبشير والتنظيم .
