Exoplanet vs 探索分形世界

Exoplanets are planets orbiting stars beyond our own solar system. This app allows you to explore all discovered exoplanets, their measured physical properties, their location in the night sky, and their host stars. An interactive model shows you the entire observable universe, all the way from the surface of the Earth to the cosmic microwave background. This app has been developed by a professional astronomer. Main features: * Interactive visualizations and animations. * Physical properties of all detected exoplanets and their host stars, updated on a daily basis. * Stunning 3D model of our Milky Way showing the location of all known exoplanets. You can zoom into any planetary system, explore how the night sky and the constellations look from the surface of other planets, or zoom out and see other local galaxies and galaxy clusters as well as the cosmic microwave background. * Visualizations of exoplanet orbits and the habitable zone. * Choose between the Open Exoplanet Catalogue, the NASA Exoplanet Archive, and the Extrasolar Planet Encyclopedia (exoplanet.eu). * Push notifications are sent out whenever a new planet is discovered. * Augmented reality sky map: point the phone towards the sky to find an exoplanet! * Interactive multi-touch correlation plots. * Solar System planets, major moons, and asteroids are included. * Explore S-Stars orbiting the black hole at the Galactic Center of our Milky Way * Background information about exoplanets and detection methods. * Full support of planets in binary, triple, quadruple systems and orphan planets. * Real-time ray tracing on the GPU.

探索分形世界 分形几何不仅展示了数学之美，也揭示了世界的本质，还改变了人们理解自然奥秘的方式； 可以说分形几何是真正描述大自然的几何学,使人们重新审视这个世界：世界是非线性的，分形无处不在。 分形几何种类 逃逸时间系统：复迭代的收敛限界。例如：Mandelbrot集合、Julia集合、Burning Ship分形 迭代函数系统：这些形状一般可以用简单的几何“替换”来实现。例如：康托集合、Koch雪花、谢尔宾斯基三角形、Peano曲线等等。 吸引子：点在迭代的作用下得到的结构。一般可以用微分方程确立。例如：Lorenz吸引子。 高尔顿钉板实验，傅立叶级数可视化，单摆周期研究，复摆与混沌，沙堆图案， 碰撞模拟，纯滚动与摆线，旋转与闪频。 DLA 扩散限制凝聚，2D水波，Rose Curve 玫瑰曲线，Lissajous Figure 利萨如图形， Phyllotaxis 叶序，Conic Curve 圆锥曲线，Super Shape 超级曲线。 另外收集互联网上常用数学公式，如最美的十个公式，高等数学微积分公式，用LaTex描述，通过浏览器展示. 化学元素周期表，高中物理化学思维导图等。 资料信息来源于互联网，仅供参考。 探索分形世界: 1.选择要欣赏的分形或数学图形，可以修改配置，查看说明。 2.选择公式手册，选择要显示条目，耐心等待公式渲染。
