Calculus is a branch of mathematics that studies motion and change. Originally called "infinitesimal calculus" or "the calculus of infinitesimals", it has two main branches: "differential calculus" and "integral calculus". Differential calculus deals with instantaneous rates of change and the slopes of curves, while integral calculus focuses on areas under or between curves. British mathematician "Isaac Newton" and German mathematician "Gottfried Wilhelm Leibniz" independently developed the foundations of calculus in the late 17th century. Calculus is an essential part of many other fields, including physics, chemistry, biology, economics, finance, and actuarial science. Before the development of calculus, mathematics was largely "motionless", it could only describe static objects. But the universe is constantly changing. From the stars in space to the cells in our bodies, nothing is ever truly at rest. Calculus is the branch of mathematics that allows us to study how things move, grow, expand, shrink, and travel.

Did you know that "calculus" originally meant “stone”? The word comes from Latin, because in ancient times, people used stones to perform calculations. Calculus is a major branch of mathematics that studies rates of change and areas under curves. Although Isaac Newton and Gottfried Wilhelm Leibniz are credited with developing modern calculus in the 17th century, its roots go much further back. Early forms of calculus appeared across different civilizations: - "Egypt (c. 1820 BC):" Papyrus records show calculations of volumes and areas. - "Greece:" "Archimedes" used the method of exhaustion to find areas under curves. - "China:" "Liu Hui" and "Zu Chongzhi" explored areas and volumes of circles and spheres. - "Middle East:" "Alhazen (965–1040 CE)" studied volumes of curved surfaces. - "India:" The "Kerala school (14th century)" developed infinite series and early forms of the Taylor series. Later, European mathematicians like "Barrow, Fermat, Pascal, and Descartes" expanded Newton’s and Leibniz’s ideas, while "Bolzano, Cauchy, Riemann," and "Dedekind" brought greater precision to limits, integrals, and real numbers. If you want to explore calculus further, there are many excellent free books available online. Here’s a list of some great "free calculus books" to help you start learning!
