Planck Scale is a forum on theoretical physics and popular science I run on my site. The original idea was due to chats with my friends, Hongbao Zhang, Hua Zhang, and Song He, who are the co-founders of the forum.
I wrote a long essay that introduces to you the forum and the whole story of openning this forum; you may read it here. Unfortunately, the essay is in Chinese. As a summary, the forum is dedicated to discussions on Theoretical Physics and related Popular Science, History of Theoretical Physics, Biographies and Stories of Theoretical Physicists.
The forum is made available to both Chinese and those who can read English, in the sense that a post can be in either Chinese or English. However, due to the potential fact that most of the early users of the forum would be Chinese, the default interface language is set to Chinese. If you do not speak Chinese but would still like to register as a user please feel free to contact me, the administrator via adminPSforum@gmail.com. I'll register for you whatever a username you like and set your default language to English.
I should mention that the forum is temporarily closed because of a hack to my website occurred in August. I'll try to reopen it asap. It seems that all the current moderators of the forum are quite busy with their career and lives, the forum does need more moderators. If you would like to be a moderator, please feel free to let me know, and I'll set it up for you.
