Who was the person to develop the laws of calcules?

The laws of calculus were developed independently by Sir Isaac newton and Gottfried Wilhelm Leibniz in the late 17th century. Newton focused on the concept of motion and change, formulating his ideas in the context of physics, while Leibniz introduced notation that is still used today, such as the integral sign (∫) and the derivative (d). Their contributions laid the foundation for modern calculus, despite the controversy over priority and credit between the two mathematicians.
