.. _logo-design: Logo and Name of GEHONG ======================= The name **GEHONG** is inspired by the historical Chinese Taoist scholar and alchemist **Ge Hong** (葛洪, 283–343), also known by his literary pseudonym *Baopuzi* (抱朴子). See: `Wikipedia (葛洪) `_ Origin of the Name ------------------ In traditional Chinese alchemy, Ge Hong was renowned for refining elixirs from diverse ingredients through mysterious techniques. This resonates with the philosophy of the GEHONG software: **assembling complex physical models and observational inputs (the “ingredients”) to generate IFS datacubes (the “elixir”)**. Originally, the name was chosen to metaphorically capture this idea of "spectral alchemy" for astronomical data. CSST Coincidence and Reinforcement ---------------------------------- By chance, the author came across a Ming dynasty painting of Ge Hong, shown below: .. image:: /_static/image/baopuzi.jpg :alt: Ming Dynasty portrait of Ge Hong :align: center :width: 60% In this painting, a mysterious symbol appears in the **top-left corner**, which strikingly resembles the structure of the **Chinese Space Station Telescope (CSST)**: .. image:: /_static/image/csst.png :alt: CSST diagram :align: center :width: 40% Given that this package was specifically developed for simulating CSST-IFS observations, this serendipitous visual echo strengthened the naming choice—**GEHONG** became a perfect fit. Logo Design ----------- Inspired by the portrait, the author worked with ChatGPT to design a custom logo for this package. The official logo includes the following elements: - A **cartoon-styled Ge Hong figure** in the center, based on the Ming dynasty portrait. - A **cartoon CSST telescope** in the top-left corner, referencing CSST's role in the project. - A **3D datacube galaxy diagram** in the top-right, symbolizing the simulated output of the GEHONG package. .. image:: /_static/gehong_logo.png :alt: GEHONG logo :align: center :height: 250px This logo reflects the unique fusion of traditional Chinese culture and cutting-edge astronomical simulation, and serves as a playful "easter egg" within the documentation.
