Scientific and cultural events are unfolding to celebrate their fiftieth anniversary. For the second consecutive day, Algerian researcher Ahmed Jabbar continues to deliver his scientific lectures at Tlemcen University as a guest of the Department of Mathematics in the Faculty of Sciences. The university's rector, Prof. Mourad Meghachou, along with its vice-rectors and the dean of the faculty, Prof. Zouhair Arar, are present, along with an eagerly awaited audience, to follow his lecture titled "The Arab Era of Algebra."

To further enrich the remarkable journey of Professor Ahmed Jabbar, it is worth noting that he has been a founding member of the Algerian Academy of Sciences and Technologies since 2015 and a corresponding member of the Tunisian Academy of Sciences, Arts, and Letters since 2019. He has been a member of the International Academy of the History of Science since 2005, and he is also a member of seven editorial boards of specialized journals in the history of mathematics. In addition, he has been honored with prestigious international awards, such as the Eugène Smith Prize awarded by Columbia University in New York in 2016, the Ibn Sina Prize presented in Paris in 2018, and the Kuwaiti Association Prize for the Development of Sciences in 2022. Despite these international accolades, he has remained dedicated to editing and publishing over 200 scientific articles, most of which focus on topics related to Arab mathematics and its history.

On the scientific stage, Professor Jabbar takes us through his works and writings into the realm of equations and numbers in an ancient civilization that is the Arab world, highlighting the great pioneers such as Al-Khwārizmī, Al-Kindī, and Ibn al-Haytham and revealing their significant contributions to the field of algebra. These contributions laid the groundwork for modern mathematical sciences, which continue to evolve. The Arab era of algebra was not just a bygone period; it was a flame that continued to burn through time and centuries, illuminating the path for researchers and students and inspiring them to pursue creativity and innovation.

In conclusion, the Arab era of algebra, as presented by Professor Ahmed Jabbar, is not merely a historical subject; it is a call to follow in the footsteps of our illustrious ancestors, an invitation to discover new horizons in the world of mathematics, and a call to believe that we are capable of achieving magnificent accomplishments that enrich human civilization as a whole. Our journey with Professor Jabbar does not end here; it is a journey that speaks to researchers and enthusiasts, nurturing minds thirsty for knowledge, inspiring and stimulating the love of learning and understanding.
