For a long time, Newton believed that there must be a mysterious force, and it was this invisible force that pulled other planets around the sun. But what kind of power is this? Until one day, Newton was thinking under the apple tree in the garden, and an apple fell at his feet. Newton finally had an epiphany and his problem was gradually solved.

Legend has it that in the autumn of 1665, Newton sat under the apple tree in his yard and thought about this problem. At this moment, an apple happened to fall. It landed at Newton's feet. This caught Newton's attention. Newton found the reason of apple falling from the natural phenomenon of apple falling-the role of gravity. This invisible force from the earth pulls the apple down, just like the earth pulls the moon around the earth.

This apple tree in Newton's hometown was later transplanted to Cambridge University. After Newton's death, he was widely praised as a hero who discovered the laws of the universe, and the story of Newton and Apple was widely circulated.

Newton's apple tree was inspired by Newton, a great British scientist, because the apple fell from the tree. This apple tree is very famous and is considered as a symbol of the spirit of scientific exploration. In fact, this is a legendary story in the history of science.

"Newton Apple Tree" not only beautifies the campus, but also conveys Newton's scientific spirit to the teachers and students of the whole school: carefully observe the changes of things and explore the mysteries of science. Newton's scientific spirit of seeking truth from facts also coincides with the motto of Tianjin University, which is also the necessary spirit and attitude of scientific workers.

Extended Information Mr. isaac newton, Chairman of the Royal Society, a famous British physicist, an encyclopedic "all-rounder" and author of Mathematical Principles of Natural Philosophy and Optics.

He described gravity and three laws of motion in the paper "Laws of Nature" published by 1687. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering.

By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.

In mechanics, Newton expounded the conservation principle of momentum and angular momentum and put forward Newton's law of motion. In optics, he invented reflecting telescope, and based on the observation that a prism diverges white light into the visible spectrum, he developed the color theory. He also systematically expressed the cooling law and studied the speed of sound.

In mathematics, Newton and Gottfried Wilhelm Leibniz shared the honor of developing calculus. He also proved the generalized binomial theorem and put forward Newton's method to approximate the zero point of function, which contributed to the study of power series.

In economics, Newton put forward the gold standard.

From 65438 to 0679, Newton returned to the study of mechanics: gravity and its influence on planetary orbits, Kepler's laws of planetary motion, and discussions with Hooke and Flamsteed on mechanics. He attributed his achievement to the book Motion of Objects in Orbit (1684), which contains a preliminary law of motion formed in principle later.
