Gauss (the prince of mathematics) said: "Mathematics is the king of science" Russell said: "Mathematics is symbols plus logic" Pythagoras said: "Numbers govern the universe" Halmos said: "Mathematics is a unique art." Misra said: "Mathematics is the highest achievement in human thinking." Bacon (British philosopher) said: "Mathematics is the key to the door of science." Bourbaki School (French mathematical studies Group) believed: "Mathematics is the study of abstract structures." Hegel said: "Mathematics is God's symbol for describing nature." Wild (President of the American Mathematical Society) said: "Mathematics is a culture that will continue to evolve." Plato said: "Mathematics is the highest form of all knowledge." Cotter said: "Mathematics is the most brilliant pearl in the crown of human wisdom." Descartes said: "Mathematics is a tool of knowledge and the source of other knowledge tools. All research sequences and The science of measurement is all related to mathematics. "Engels (philosopher of dialectics of nature) said: "Mathematics is the study of quantitative relationships and spatial forms in real life." Klein (American mathematician) said: "Mathematics is a rational spirit. , so that human thinking can be used to the most perfect degree." Galileo said: "Give me space, time, and logarithms, and I can create a universe." "The books of nature are written in the language of mathematics." Newton said: "No Great discoveries cannot be made by making bold conjectures," Halmos said: "Mathematical creation can never be achieved by inference alone. It usually starts with some vague guesses, trying to figure out possible generalizations, and then makes various conclusions. A very confident conclusion. Then organize your thoughts until you see the clues to the facts. It often takes a lot of effort to put everything into logical proof. This process does not happen overnight. It requires many failures, setbacks, repeated guessing and speculation, and it is common for several months to be wasted in temptation. " Laplace said: "In mathematics, our main tools for discovering truth are induction and simulation." Wittgenstein said: "Mathematics is a variety of proof techniques." Hua Luogeng said: "New mathematical methods and concepts, Often more important than the solution of the mathematical problem itself." Napier said: "I have always devoted my energies and talents to escape from the heavy and monotonous calculations." Kepler said: "The best years of my life have been pursued in pursuit of that goal... …. . The book has been written. It doesn't matter whether modern people read it or future generations read it. It may take a hundred years before there is a reader." Napoleon said: "Only a country with the vigorous development of mathematics can show the strength of its national foundation. The development of mathematics is closely related to the highest good and the prosperity of the country." Einstein said: "One reason why mathematics is respected above all other sciences is because its propositions are absolutely reliable and indisputable, while other sciences often In danger of being overturned by newly discovered facts. …. Another reason why mathematics has a high reputation is that mathematics enables natural science to achieve theoremization and gives natural science a certain degree of reliability. "Qiu Chengtong said: "After modern high-energy physics reaches quantum physics, many experiments cannot be done at all. You can do calculations at home with paper and pen. This is not far from what mathematicians think, so mathematics has incredible power in physics." R?ntgen said: "The first is mathematics, the second is mathematics, and the third is mathematics." Hua Luogeng said: "The vastness of the universe, the tinyness of particles, the speed of rockets, the ingenuity of chemical engineering, the changes in the earth, the mysteries of biology, and the daily use of Complex, mathematics is used everywhere. " Von Neumann said: "Mathematical methods penetrate and dominate all theoretical branches of natural science. It has increasingly become the primary measure of scientific achievement. ”
