Fenced area
A farmer invited engineers, physicists and mathematicians to enclose the largest area with the least fences.
The engineer fenced a circle and declared that it was the best design.
The physicist said:? Remove the fence and form a long enough straight line. When it surrounds half the world, it has the largest area. ?
The mathematician gave them a big laugh. He surrounded himself with several fences and said, I am outside the fence now. ?
Feeling:
The engineer's design is both practical and beautiful, isn't it? Optimal design? . Physicists have a strange imagination in their thinking, and fences can be decomposed and opened indefinitely. It seems that the closed area is already? The biggest? . Mathematicians surround themselves with few fences and say, I am outside the fence now. ? Engineers and physicists try to circle the largest area, while mathematicians circle the smallest area first. People say to take a step back and broaden their horizons, but mathematicians don't just take a step back, but do the opposite. ? The opposite? This is a quality of reverse thinking.
Reverse thinking is an integral part of creative thinking. Before we face it? Heavy mountains and heavy waters? At this time, reverse thinking often leads us to find? A bright future? This road. Mathematics teaching should make reverse thinking become students' conscious consciousness and practical behavior.
Prize-winning works of primary school students' mathematical manuscripts (II) Famous mathematical sayings
Pure mathematics enables us to discover concepts and laws related to these concepts, which give us the key to understand natural phenomena.
A. Einstein
History makes people wise, poetry witty, mathematics subtle, philosophy deep, morality grave, logic rhetoric able to contend.
F. bacon
In the field of mathematics, the art of asking questions is more important than the art of answering questions.
G. singing poets and leading singers
God created integers, and all other books are artificial.
Leopold Kronecker
For us, the value of mathematical knowledge is not only because it is a powerful tool, but also because mathematics itself is perfect. In the internal or external development of mathematics, we have seen the purest logical thinking activities and the most advanced aesthetic embodiment of wisdom and vitality.
A. Pringsheim
One reason why mathematics is more respected than all other sciences is that his proposition is absolutely reliable and indisputable, while other sciences are often in danger of being overthrown by newly discovered facts. ? Another reason why mathematics has a high reputation is that mathematics makes natural science theorem and gives it certain reliability.
[Name] Albert Einstein (Jewish theoretical physicist)
Mathematics is a spirit, a rational spirit. It is this spirit that inspires, promotes, inspires and drives human thinking to the most perfect degree, and it is this spirit that tries to decisively influence human material, moral and social life; Trying to answer questions about human existence; Strive to understand and control nature; Try your best to explore and establish the deepest and most perfect connotation of the knowledge you have learned.
Klein
Besides language and music, mathematics is one of the main ways to express the free creativity of human mind, and mathematics has become a medium to understand everything in the universe through theoretical construction. Therefore, mathematics must remain the main component of knowledge, skills and culture, while knowledge and skills must be passed on to the next generation and culture must be passed on to the next generation.
Hermanville
Mathematics is the king of science.
Gauss
Mathematics is symbol plus logic.
Russell
Numbers dominate the universe.
I recommend it carefully.
