Sir Isaac Newton's Mastery of Mechanics and the Discovery of Universal Gravitation
Sir Isaac Newton‘s monumental effort in the field of mechanics ___1___ （ revolution）our understanding of the natural world.
His groundbreaking work, _2_（ particular） the formulation of the law of universal gravitation, demonstrated how every mass in the universe exerts an __3___（ attract） force on every other mass. This profound insight did not come easily—Newton spent years in rigorous study, _4_（fortify） by his
intellectual fortitude, to unravel the mysteries of motion and gravity.
Before Newton, the heavens seemed an impenetrable（不可理解的） fortress, beyond human __5__（comprehend）. Yet, his discoveries provided a sense of comfort to scientists, as they could now explain celestial and terrestrial motion with precise mathematical __6__（law）.
His three laws of motion and the concept of gravitational force made the cosmos feel less like an unconquerable fort and more like a comprehensible, orderly system. Newtonian mechanics fortified the foundations of classical physics, _7_（enable）later scientists to explore and predict phenomena with confidence.
The comfortable certainty of his equations allowed engineers to build bridges, launch satellites, and understand planetary orbits. Without Newton’s fortitude in __8_（challenge） existing beliefs, modern science might still be confined within the fortress of medieval thought.
In essence, Newton’s work dismantled the intellectual forts that once separated physics _9_ astronomy, unifying them under a single theoretical framework. His legacy stands as an unshakable fortress of scientific achievement, inspiring generations to push beyond the _10_（boundary） of knowledge.
