Basic particle diagram

The exhibit consists of a ball circulation transmission mechanism, a projector, a rope net cover, and a camera. The exhibit consists of two parts: desktop projection interaction and ball circulation transmission mechanism. When unmanned, the desktop projection displays a dynamic scene of red and blue virtual balls scattering outward from the central pillar of the desktop, floating and colliding in the projected desktop image. When two colored balls collide, a transparent ball is generated, which is a composite particle composed of two or more basic particles. visitors stands in the exhibit experience area and completes four game tasks: synthesizing protons, synthesizing neutrons, synthesizing atomic nuclei, and synthesizing atoms according to the on-screen prompts. Small ball circulation transmission mechanism: This device is an automatic mechanical device, where the small ball rises from the bottom to the top and descends in a circular motion. It understands the characteristics of four types of particles - protons, neutrons, electrons, quarks - as well as four basic forces - strong, weak, electromagnetic, and gravitational. The exhibit are presented to visitors through interactive projection on the desktop.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

Basic particles are the most fundamental units that make up matter, and are currently the smallest and indivisible microscopic particles known. In the Standard Model theory, elementary particles are mainly divided into two categories: first, fermions, including quarks and leptons. 2、 Bosons, such as photons, gluons, W and Z bosons, etc.
