Mathematical Physicist Yakov Gregory Sinai, (b. 21st September 1935, 78 years old) has been awarded the prestigious Abel Prize for 2014 by the Norwegian Academy of Science and Letters (NASL). The President of the NASL, Nils C. Stenseth, announced the winner of the 2014 Abel Prize at the Academy in Oslo on 26 March 2014.

The Abel Prize recognizes contributions of extraordinary depth and influence to the mathematical sciences and has been awarded annually since 2003. It carries a cash award of NOK 6,000,000 (about USD 1 million). Y. Sinai is 14th mathematician to win this prize in last 12 years.  He is a professor at Princeton University and Landau Institute for Theoretical Physics (Russian Academy of Sciences). This prize was awarded to him, for his fundamental contributions to dynamical systems, ergodic theory, and mathematical physics.


Some of the top-notch works by Prof. Sinai are as below:

  • Kolmogorov–Sinai entropy
  • Sinai’s billiards
  • Sinai’s random walk
  • Sinai-Ruelle-Bowen measures
  • Pirogov-Sinai theory.

The announcement video is live at Abel Prize’s official website.

  1. Professor Yakov Sinai,

    I have the honor to congratulate you for the obtainment of Abel Prize 2014. You win it by your «fundamental contribution to dynamical systems, ergodic theory, and mathematical physics».

    I would comment your saying

    Mathematics and physics must go together as horse and carriage

    and that of Jordan Ellenberg

    Sinai has worked on questions relating to real physical systems “with the soul of a mathematician”.

    Mathematics is done by the Soul and it is the horse. The immortal soul discovers the true and evident first principles and the reason propagates their truth by the demonstration.
    This horse must be a real being and not a game as preaches Modern Mathematics. The Modern Mathematics misses the essential qualities of the true mathematics. These qualities are: Exactitude, Necessity, immutability and universality. More Modern Mathematics is not founded and contains paradoxes.

    It is well known that physical results can never attain the perfection. This perfection is only attained by the pure mathematics. In the applications of mathematics, you are a master and nobody can deny your major contribution to the progress of humanity. To approach nearer and nearer to the perfection, it is necessary to use the true mathematics which is firmly founded.

    Rachid Matta MATTA, four years younger than you, advocated his life for the foundation of mathematics, and after fifty years of hard research, he succeeds to prove rigorously the fundamental theorem of geometry: Euclid’s fifth postulate. The four methods attached to this email are extracted from my book « The Methods Of Demonstration Of The Parallel Theorem» and they confirm what I am saying. A great mathematician, like you, will see easily the contradiction in hyperbolic geometry and the necessity to reject it.

    The winner of Abel Prize2014 knows very well that Euclidean geometry will become the only true geometry, the real space will be of three dimensions and all objects, facts and phenomena in this space will be described by the propositions of Euclidean geometry.

    The real space will receive all your valuable works at the only condition is that you avoid the use of the mathematical infinite. The infinite length and the infinite number do not exist. All that exists is finite. The true nature of number is the object of my book «The Number, Neither Reality, Nor Infinity, Nor Continuity». The use of Euclidean geometry conducts to the true arithmetic and the true algebra. I hope that all your papers concerning the applications of mathematics will use the true mathematics to approach from the perfection, and this approximation is enough for explaining the facts in the nature.

    I am sure that your intellectual honesty and scientific probity will push your conscience to call the mathematical community to recognize the validity of Euclidean geometry and to render justice to Rachid Matta MATTA, who worked hardly 50 years to find the correct proof for the fundamental theorem of geometry known under the name of Euclid’s fifth postulate.

    The President and members of the Board of Abel Prize,

    I have the honor to attract your attention, as I did in my attached e-mail sent to Professor Yakov Sinai, the laureate of Abel Prize 2014, on the following points:

    1) The mathematician Rachid Matta MATTA, works for the honor of the human spirit, and after fifty years of hard research, he proved Euclid’s fifth postulate infirming the mathematicians who consider it impossible to be proved. The ranking of Parallel postulate between the theorems founds firmly Euclidean geometry and rejects the Non-Euclidean geometries.
    2) You know that mathematics, constituted by Geometry, arithmetics, and algebra, is the fundamental discipline.
    3) The criteria of mathematics are: exactitude, necessity, immutability, and universality.
    4) The main objective of the Abel Prize is to recognize pioneering scientific achievements in mathematics. This achievement must use the true mathematics.
    5) All the laureates of Abel Prize have not used the true mathematics, because their works used the Non-Euclidean geometries, or the disciplines based on mathematical infinite.
    6) I affirm that the Non-Euclidean geometries are inconsistent and the mathematical infinite does not exist because there is neither a biggest length, nor a larger number. My affirmation is supported by my books respectively entitled in French:
    a) «Les Méthodes de Démonstration du Théorème de la Parallèle»
    b) « Le Nombre Ni Réalité, Ni Infinité, Ni Continuité»

    7) The four methods attached to this email are extracted from my first book mentioned above. In studying them you can see easily that hyperbolic geometry contains contradiction, therefore it is inconsistent. Any wise man knows that a straight line cannot rotate at the same time in two opposite sens, (The Method of impossible rotation)

    8) Teaching the true mathematics offered by my mathematical works enables the mathematicians and the scientists to produce real achievements.

    9) As you are a qualified mathematician possessing the intellectual honesty and the scientific probity, which are the essential qualities of the man of science, you will never accept that error remains in the mathematics. I am sure you do your best to push the mathematical community to recognize the mathematical truth and the validity of Euclidean geometry.

    10) I hope that Norwegian universities will be the pioneer to stop to teach the erroneous disciplines. Only the true mathematics, rigorously founded by my books, can stimulate children and youth to become interested in mathematics.

    Best regards,

    Rachid Matta MATTA
