According to the role of ʿ Abd al-Ghaffā r Najm al-dawla in the introduction of modern sciences to Iran, we will know PHYSICS is one of the sciences that he has influenced on transition of it. ʿ Abd al-Ghaffā r had essays and tranlations in this field of study. Some of his works in PHYSICS are: Jarr-i Thaqῑ l (translation from Poinsot), Takā fū ʾ-i Quwā (statics), PHYSICS and chemistry and ʿ ilm-i bukhā rā t. Until now we achieved two transcriptions of his works. First, the book ʾ Uṣ ū l-i ʿ Ilm-i Sitā tῑ k, which he translated into Persian on 1277 A. H. On the first page of this book he said: “ the meaning of statics is ʿ ilmi muwā zinih-i ʾ ajsā m” . The other book is PHYSICS that was written at request of Mukhbir al-dawla, minister of sciences and mines, on the 1293 A. H. for the use of public, not only for educated people. Najm al-dawla in this book expresses different concepts of modern PHYSICS in a simple word, and does not use numerical and parametric issues. These two books are transcripts and have not been published. Also a French printed book named Nouvelles Ré cré ations Physiques et Mathé matiques written by M. Guyot and is kept in Library, Museum and Document Center of Iran Parliament was at ʿ Abd al-Ghaffā rʼ s disposal that may help us to have better perception. The purpose of this article is review and presentation of above books as a part of first works of modern PHYSICS in Iran and especially because of their relation to ʿ Abd al-Ghaffā r Najm al-dawla.
