In ancient times, scientific knowledge was obtained with limited means. Nevertheless, despite these challenges, people succeeded in acquiring knowledge that transcended the limits of their era through observation and rational reasoning. One such individual was the Greek mathematician and geographer Eratosthenes, who lived in 235 BCE. His method for calculating the Earth’s diameter is still regarded today as a prime example of scientific ingenuity.Eratosthenes’ MethodEratosthenes knew that on the

Liber Abaci is a foundational mathematical work written by Italian mathematician Leonardo Fibonacci in 1202 and revised in 1228. Written in Latin, this book is regarded as one of the turning points in modern European mathematics due to its critical role in introducing the Hindu-Arabic numeral system to Europe. Liber Abaci had a profound impact not only on theoretical mathematics but also on commercial calculations and everyday practical applications.Purpose and ContentThe primary aim of Liber Ab

Murphy’s Law is a concept rooted in engineering safety principles, originally expressed in its most basic form as “if anything can go wrong, it will go wrong.” Over time, it has become established in popular culture, scientific analyses, and management theories as a principle of pessimistic probability, representing a perspective that emphasizes systems’ vulnerability to failure and the inevitability of errors.Historical Origins and EmergenceThe naming and formulation of this concept stem from e

Science History Conversations is a work compiled in interview format by Sefer Turan, containing the life, memories, and views on the history of science of Turkish historian of science Prof. Dr. Fuat Sezgin. The first edition was published in 2010 by Timas Publishing under the title “Fuat Sezgin, Historian of the Sciences”; subsequent editions have been presented to readers under the title “Science History Conversations”. The work explores the life story, academic journey, and perspective on the

Maragheh Observatory was an astronomical center established in the city of Maragheh in Azerbaijan in the 13th century by the renowned scholar Nasir al-Din al-Tusi on the orders of the Ilkhanid ruler Hulagu Khan.Recognized as one of the most important scientific institutions of the medieval Islamic world the observatory functioned both as a research center for observational activities and as a higher education institution. Some historians have regarded it as the “first modern observatory” that se

The Tusi Couple is a mathematical mechanism developed by the 13th-century astronomer Nasir al-Din al-Tusi (1201–1274). Its primary function is to generate linear motion from the combination of two circular motions. Tusi developed this mechanism to address and correct a fundamental problem in Ptolemaic astronomy, particularly the use of the equant point.The term Tusi Couple is not limited to a single device; it is also used as a general term encompassing various mathematical tools Tusi developed

Archē (Ancient Greek: ἀρχή) was used in Ancient Greek philosophy to mean first principle, origin, fundamental substance, or primary element. For the Milesian natural philosophers Thales, Anaximander, and Anaximenes, archē denotes the underlying, more fundamental element behind the cycles of change and becoming, lying beneath appearances that are subject to transformation. The central question posed by these thinkers was: “What lies beneath all things, enduring beyond change?”The Milesian school

Prof. Dr. Atilla Bir is an academic who has made contributions in both engineering sciences and history of science. He completed his education in electrical and control engineering in Germany and spent many years as a faculty member at Istanbul Technical University, teaching both theoretical and applied courses in systems and control engineering. Professor Bir, who bridged his engineering expertise with historical inquiry, is particularly known for his technical and historical analyses of mechan

Electricity Already Existed in NatureElectricity existed in nature long before humans discovered it. Lightning struck across the sky, and massive electrical discharges occurred when clouds rubbed against each other. Even some animals — such as electric eels — could generate their own electricity. But for a long time, humans did not understand what this power was.Earliest Signs of Electricity in AntiquityIn the 600s BCE, the ancient Greek philosopher Thales noticed something curious when he rubbe

Throughout history, humans have examined the materials around them and attempted to classify them. Although in ancient times substances such as water, air, earth, and fire were considered “classical elements,” the discovery of true elements began only after the 1600s. An element is a pure substance that cannot be broken down into smaller components.Organizing the ElementsIn the 1700s and 1800s many new elements were discovered. However, arranging these elements in a meaningful way proved difficu
