“THE DEVELOPMENT OF GEOMETRY AND MATHEMATICS AT THE MARAGHA OBSERVATORY” - PREFACEI got acquainted with the author of this book in June of 2002. The society of “Education” invited me to the scientific-practical conference about “Scientific services of Nasiraddin Tusi and N. Tusi in the activity of the writer and researcher Ramiz Gasimov (Daniz)” and offered me to make speech about his book “Christopher Columbus, Nasiraddin Tusi and discovery of America”. To say the truth I was surprised when heard the author’ name. Probably, readers know that, Ramiz Daniz works in the Oil Refining Factory of SOCAR as a worker and isn’t high-educated, but I don’t want to speak about his auto-biography. As the name of the book was too haughty, I investigated the author’s previous activity and it turned out that, he is the author of several books and trilogy written in this field. After reading his books I asked myself: Who is Ramiz Daniz? Is he a writer or researcher and what does he want to gain? I understood that, he has his own style and tries to combine notions of “writer” and “researcher” and is the first author, who has achieved it. For example, he is a researcher in the above mentioned book and books used for this work prove it. Of course, most of issues mentioned in the book are disputable. But the author shouldn’t be accused for it as his purpose was to lay bare the truth by means of discussions and investigations. Scientific achievements of Nasiraddin Tusi also were mentioned in the book. The author has mentioned that, the scientist’s “Tahriru Uglidis” was used as a source by most well-known scientists of Europe. According to the author, Tusi had developed trigonometry as an indepen-dent branch of science. Investigations prove that, H. Mammadbayli’s book is almost the only monumental work written about Nasi-raddin Tusi. It turns out that, we can get the most detailed information about N. Tusi by means of the encyclopedia “Cambridge history of Iran”. It is a great gap for Azerbaijani science. Ramiz Daniz gives interesting information about Tusi’s activity in mentioned book. It shouldn’t be forgotten that, he is a writer and has his own style. I think that, it is necessary to inform readers about the Azerbaijani scientist in an interesting and new way. The author has used historical facts in order to describe Nasiraddin Tusi’s activity. He has analyzed the development of cosmography in the world and mentioned roles of Azerbaijani scientists and especially Nasiraddin Tusi in this field. He especially investigated Tusi’s activity in fields of astronomy, mathematics and diplomacy. The author has proved that, devices invented by N. Tusi are kept in most museums of the world and they had a great role in the development of scientists all over the world. He has named one of headings of the book “N. Tusi’s scientific achievements of global importance”. He has mentioned that N. Tusi’s “Tahriru Uglidis” (“Recension of Euclid’s Elements”), “Shaklul-qita” and “Collection of Counts” were basis for the development of geometry. The author has mentioned B. A. Rozenfeld’s following thought in order to prove this assumption: “Nasiraddin refused to prove the postulate of parallelism by means of two axioms and postulates and used only one simple postulate and it was an important step for Lobachevski’s proof”. Ramiz Daniz is a hard-working writer and so, we can wait for his next books soon. I wish him success.
