Sir Isaac Newton's early years influenced his revolutionary ideas in physics. As a bright student, he demonstrated a keen interest in mathematics and natural philosophy. His time at the University of Cambridge, especially during the Great Plague, allowed him to engage in solitary experimentation, leading to insights that shaped his theories on gravity and optics. Newton’s exploration of the cosmos and rigorous scientific inquiry laid the foundations for classical mechanics, fundamentally altering the understanding of physical laws and establishing his position as a pioneering figure in science.
