| Project | Wolfram Alpha | GeoGebra | zzllrr Mather |
|---|---|---|---|
| Name Meaning | Founder Name+Alpha (Greek Letter α) | Mixed from the words, Geometry and Algebra | Nickname + Mather (people related to Math) |
| 名称来源 | Wolfram（创始人名字Stephen Wolfram，美籍英国人）+Alpha（希腊字母表第1个字母α） | Geometry(几何)与Algebra(代数)英文单词的合成，创始人Markus Hohenwarter | zzllrr(发起人网名)+Math（数学英文单词）+er(英文词缀表示与…有关的人) |
| Country from | USA | Linz, Austria | Nanjing, China |
| 项目起源所在地 | 美国，北美 | 林茨，奥地利，欧洲 | 南京，中国，亚洲 |
| Timeline | before 2009(Conceived and Mathematica had been released for 20 years then) | 2001(project started), 2011(Materials launched) | 2019(demo version open-sourced on GitHub) |
| 时间线 | 2009(发布)，且当时Mathematica(与之密切相关)已发布20年 | 2001(项目启动)，2011年课件库 | 2019(demo演示版开源发布) |
| Commercial/Free | Commercial(but free for some limited use) | Open-Source(but not free for commercial use) | Open-Source and Free |
| 商业性质 | 商用软件(但可免费使用部分受限功能) | 开源（非商用免费） | 免费开源 |
| Software Type | Website/70+ APPs，B/S, written in 15 million lines of Wolfram Language code and runs on more than 10,000 CPUs. | HTML5 Website/(5 APPs) | No Website/APP now, but webpage file package is available |
| 软件形式 | 有网站，移动APP（70+子APP），主要基于B/S架构，1500万行源代码，1万个CPU。 | 有HTML5网站，移动APP（5个子APP），核心代码置于浏览器或客户端，不过多依赖Server | 暂无网站和APP，去中心化，无需注册，免安装，包含源码的网页文件包形式 |
| Goals | Make all the world’s systematic knowledge computable | Power innovation in STEM edu services | Make mathematics easier to reach, learn and spread. |
| 软件目标 | 作为大型STEM工具，服务于商业工程、学术机构并从中适当盈利 | 帮助老师设计有趣的教学方法，让数学教学更充满活力 | 让数学更易被系统化、结构化地学习、探索和传播。 |
| Philosophy | A computational knowledge engine or answer engine | An interactive application, intended for learning and teaching mathematics and science from primary school to university level | Decentralize, but maintain a high degree of internal unity and simplicity. 5 Protocols: Organism, Offline Computation & Online Connection, Energy Consumption Minimization, Open Access, Consensus & Cooperation |
| 软件思想 | 解决所有可计算问题的在线服务（不仅限于数学专业问题） | 交互式小学到大学的数学教学工具 | 去中心化，但又保持内部高度统一和极简。遵从下列五个核心协议：有机体、离线计算与联网、能耗最小化、开放获取、共识与合作 |
| Early function point or initial target | turn Mathematica to be a web service | overcome shortcomings of The Geometer's Sketchpad,which is not free of charge or not compatible with LaTeX | overcome shortcomings of existing Math web services which are highly fragmented and inconsistent or unreachable offline |
| 早期功能点或初心 | 拥抱web，并将Wolfram Mathematica的计算功能web化 | 突破几何画板的收费及不支持LaTeX的缺陷 | 突破Web服务不稳定且无法离线使用和数学碎片化的倾向 |
