The mind of a person who was a scientist in:

* Medicine;

* Philosophy;

* Chemistry;

* Physics;

* Translation;

* History;

* Astronomy;

* Founder of astrophysics;

* In pharmacy, the founder of pharmacology;

* In geography, the founder of historical geology;

* Founder of the science of minerals and weights, and determined the specific gravity of many minerals, gems, and stones;

* Was a founder of the science of comparative religion and the scientific method of historical research;

* Founder of geodesy;

* In space, his book "The Law in the Science of the Body and the Stars", proving the spherical shape of the Earth and its rotation around itself on an inclined axis and around the Sun, and providing a concept of the force of gravity on Earth, which preceded the English scientist Isaac Newton;

**He was the first to say that the Earth rotates around its axis 1000 years ago.**

**Without any modern means, he knew the circumference of the Earth with an accuracy of 99.7% of today's measurements.**

**He invented a way of drawing maps that show the different reliefs on the globe.**

**He was the first to discover that the speed of light is faster than the speed of sound.**

**He invented seven ways to determine the direction of north and south.**

**He discovered a mathematical system for determining the beginning of the seasons.**

**He wrote more than 120 books in all sciences.**

**He was able to determine the longitude and latitude lines, in addition to many other important discoveries.**

**He put a device that measures the movements of the sun and the moon, and invented the cylindrical astrolabe used to observe the planets and stars and determine the dimensions of distant objects and their heights from the Earth's surface.**

**He explained some phenomena related to the flow of fluids, the phenomenon of tides and the flow of light, and observed that metals expand with heat and contract with cold.**

**He addressed the formation of the Earth and the composition of its surface and what it is subjected to, such as earthquakes, volcanoes, and floods.**

**He mastered several languages, including Arabic, Persian, Khurasani, Greek, Hebrew, Syriac, and Sanskrit.**

**George Sarton defined him in his book (Introduction to the Study of the History of Science) by saying about him:**

"He was a traveler, philosopher, mathematician, astronomer, geographer, and encyclopedic scientist, one of the greatest greats of Islam and one of the greatest scientists in the world."

**The German orientalist "Schau" described him, saying:**

**Arthur Pope confirmed that he is one of the greatest minds of all time.**

**NASA named one of the craters on the moon after him in 1951.**

**The tenth/eleventh century AD was called the "Era of Al-Biruni".**

**He is the Muslim scientist: "Abu Rayhan Muhammad ibn Ahmad Al-Biruni."**

The greatest scientific mind in human history is the mind of Abu Rayhan Muhammad ibn Ahmad Al-Biruni, a Muslim scientist who lived in the 10th/11th centuries AD. He was a polymath, making contributions to many fields of science, including medicine, philosophy, chemistry, physics, translation, history, astronomy, astrophysics, pharmacology, geography, geology, mathematics, geodesy, and comparative religion.

Al-Biruni is considered one of the most important scientists in history. His work was groundbreaking and had a significant impact on the development of science. He was the first to say that the Earth rotates around its axis, and he was able to calculate the circumference of the Earth with remarkable accuracy. He also made significant contributions to the fields of astronomy, geography, and mathematics.

Al-Biruni's work was not limited to science. He was also a scholar of religion and philosophy. He wrote extensively on the religions of the world, and he was a proponent of religious tolerance. He also believed in the importance of scientific inquiry, and he encouraged people to question the status quo.

Al-Biruni's work is still relevant today. His contributions to science have had a lasting impact, and his ideas about religion and philosophy continue to be debated. He is a true giant of science and thought, and his work continues to inspire people around the world.
