清荷素养 vs Three

通过法治安全、心理健康、家教科普、生涯规划等课程学习，提高家长对家庭教育重要性的认识，转变家教理念；帮助家长了解青春期孩子特点，习得科学家教方法，提升家长自身素质和家庭教育能力，和谐亲子关系，从而助力孩子健康成长。这个课程，以分层教育和分类指导形成多指向的学习模块，搭建家长自主选择、自主发展的、以微信小程序为学习平台的呈现形式，线上线下相结合，以满足家长随时随地利用碎片化时间学习的需求。

1. For a batter observation, all volumes are enlarged by many times (the range of gravity in the real universe is much larger, and the planet is much smaller, so don’t worry about breaking the Roche limit) 2. Users can add up to 7 Sun, and randomly distribute them to nearby spaces. 3. Users can add an asteroid matrix. Asteroids have no gravity (negligibly small in the reality) and are only affected by Suns. (Well, in fact, it is afraid that the cpu is limited, and it is impossible to calculate the mutual gravitational force of too many stars.) 4. The three-body system is very unstable, and it is prone to gravitational slingshot effect. If a star is too far away from other stars, it may never come back. 5. However, users can also turn on an additional r/10 parameter to increase the gravitational force of stars at a long distance and make it return to the system (after turning on the parameter, it can only be used for demonstration, and the data has no reference value).
