al-Jildaki

[4] In his writings he reveals that he spent seventeen years traveling through Iraq, Anatolia, Yemen, North Africa, and Syria.

[5] Based on a speculative vocalization of his Nisba as "al-Jaldaki ", some 20th century writers like Henry Corbin suggested that he was originally from Jaldak, a town in Khorasan before emigrating to Egypt.

[8] Instead, he notes that all the biographical information known about him –like his Turkic name "Aydamir", places of residence and native language – would make sense only when set against a Mamluk background.

[10] Al-Jildaki was one of the last and one of the greatest of medieval Islamic alchemists, he was the author of scientific works such as the al-Misbah fi Ilm al-Miftah (المصباح فی علم المفتاح, Key of the Sciences of Lights) and alchemical treatise Kitab al-Burhan fi asrar 'ilm al-mizan (کتاب البرهان فی اسرار علم المیزان, The Proof Regarding Secrets of the Science of the Balance).

[5] Manouchehr Taslimi mentioned in his doctoral thesis from the University of London in 1954 that Al-Jaldaki spent seventeen years on his scientific travels.

He laid the basic building block for the creation of the "Law of definite Proportions" in chemical union, and explained it in detail, which Kepler, Galileo, and Newton later relied on in their studies.

He gave a detailed description of the method of prevention and necessary precautions against the danger of inhaling gases resulting from chemical reactions, and thus he was the first to think of inventing and using respirators in chemistry laboratories.

Al-Jaldaki was aware of the electronic structure of the atom, as he compared it to the solar system in his famous poetry and wrote many scientific books that were circulated in many libraries around the world, but most of them are still in manuscript form.

[5] Omar Rida Kahhala says in his book "العلوم البحتة في العصور الإسلامية Pure Sciences in Islamic Ages":"...However, Al-Jaldaki is considered one of the greatest scholars knowledgeable about the history of chemistry and what was written about it before him.

He was fond of collecting chemical works and interpreting them, and it was his habit to quote entire paragraphs from famous people who preceded him, such as Jabir bin Hayyan and Abu Bakr Al-Razi.

[5] Eric John Holmyard mentions in his book "Chemistry to the Time of Dalton":"Al-Jaldaki concluded with complete aplomb that substances do not interact with each other except in fixed proportions and weights.

"Abdul Razzaq Nofal adds in his book "المسلمون والعلم الحديث Muslims and Modern Science":"Five centuries after Al-Jaladaki's death, the scientist Joseph Proust announced the law of definite proportions in the chemical union, and its meaning is the same as Al-Jaldaki's theory.

"He has a book entitled natayij al-fikr fi 'ahwal al-hajar (نتائج الفكر في الكشف عن أحوال الحجر, The Results of Thought in Revealing the Conditions of Stone), which he wrote in Cairo in the year 742 AH/1341 AD.
