Abu Rayhan al-Biruni (973–1048) left behind a scientific legacy that is currently being studied in various countries around the world. The locations where he lived and conducted his research have always attracted public interest.
According to historical sources, in 1037, Sultan Mahmud of Ghazni took Biruni with him during his campaign in India. Along the way, the sultan's army conquered several cities and fortresses, including the fortress of Nandana, which is situated at the foot of high mountains.
To the west of the fortress rises a mountain, while a vast plain stretches to the south. It was here that the scholar used a simple astrolabe to measure the movement of the Sun and calculated the length of the Earth's radius, which, based on his calculations, was over 12,803,000 gaz (approximately 6,315 kilometers). This value differs by just 5 kilometers from today's precise measurements.
The remnants of Biruni's laboratory are preserved in the fortress of Nandana, located in Jhelum District. At one time, this fortress served as a scientific laboratory for Biruni. He lived there for a period, conducting his calculations and research.
The ruins of this fortress have survived to this day and are located in the Punjab province of Pakistan. Currently, the fortress is in a significantly dilapidated state. In February 2021, Pakistan's Prime Minister Imran Khan issued an order for the restoration of this historical monument and its transformation into an international tourist center. However, for various reasons, very few tangible actions have been taken in this direction so far.
— Recently, I participated in an international conference in Islamabad (Pakistan) on the topic "Education and Empowerment of Women in the Muslim Community: Experience and Opportunities" on behalf of the Center for Islamic Civilization of Uzbekistan, — says Gulnora Ganieva, head of the research department at the Center for Islamic Civilization of Uzbekistan.
During the conference, we held a meeting with the Ambassador of Uzbekistan to Pakistan, Alisher Tokhtaev, and the director of the "Babur Heritage" Center at Punjab University, Professor Rukhshona Iftikhar. The meeting also discussed the study of the "Biruni Laboratory," located within the fortress of Nandana.
Currently, the leadership of the Center for Islamic Civilization of Uzbekistan is considering organizing a scientific expedition to Pakistan to study this historical site, where our great ancestor Abu Rayhan al-Biruni worked for a period and made significant discoveries.
