Science popularization interaction device of Yami triangle

Abstract

The invention discloses a popular science interaction device of a Yami triangle, which belongs to the technical field of popular science interaction equipment, and is characterized by comprising an interactive display and an entity matrix lamp synchronously displayed with the interactive display, the entity matrix lamp is formed by arranging a preset number of led lamps capable of being independently turned on and turned off according to a Young's triangle arrangement mode, the interactive display is connected with the entity matrix lamp through RS232 serial port communication, and the system has the beneficial effects that the system is communicated with the entity matrix lamp and synchronously displays, so that the interestingness and the interaction are increased, the achievement sense of an operator can be highlighted, and the user experience is improved. Therefore, the rule can be understood more deeply; an operator can intuitively and personally experience the principle and change trend of an obscure formula in the interaction process, so that a learner can intuitively understand the learned probability, and more skillfully master theoretical knowledge and further understand a boring formula by combining the learner with the Yanghuang triangle.

Description

Technical field: [0001] The invention belongs to the technical field of popular science interactive equipment, and more specifically relates to a popular science interactive device of Yang Hui Triangle. Background technique: [0002] Pascal's triangle is Yang Hui's triangle, a geometric arrangement of binomial coefficients in a triangle. Except for the leftmost and rightmost numbers in each row, each number of Pascal's triangle is equal to the sum of its upper left and upper right numbers. It looks like a triangle. It first appeared in China in Yang Hui's "Detailed Nine Chapters Algorithm" in the Southern Song Dynasty It got its name, and Yang Hui explained in the book that it was quoted from Jia Xian's "Book of Releasing Locks", so it is also called Jia Xian's triangle. [0003] The most familiar of Yang Hui's triangle is the basic feature of Yang Hui's triangle, that is, each number is equal to the sum of the two numbers above it, and the law of binomial coefficient: (a+b...

Problems solved by technology

[0005] In order to solve the above problems and overcome the deficiencies in the prior art, the present invention provides a popular science interactive device for Yang Hui's triangle, which can effectively solve the problem of knowing that the functions involved in Yang Hui's triangle cannot make learners feel the functional relationship more intuitively, and cannot Functional relationship and Yang Hui's triangular sequence are organically combined for cognition and learning, so that learners can only form vague and independent questions about the corresponding functions
