SMTH BBS

SMTH BBS is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand SMTH BBS rather than just read about it. In short: Shuimu Tsinghua (Chinese: 水木清华; pinyin: shuǐmù qīnghuá; abbreviated as SMTH) BBS is the first and one of the most popular bulletin board system sites among the universities in China. Hosted by Tsinghua University, it is recognized for its diversity and depth of topics.

Key takeaways

  • SMTH BBS belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect SMTH BBS to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of SMTH BBS from memory before moving on to harder problems.

Reference excerpt

Shuimu Tsinghua (Chinese: 水木清华; pinyin: shuǐmù qīnghuá; abbreviated as SMTH) BBS is the first and one of the most popular bulletin board system sites among the universities in China. Hosted by Tsinghua University, it is recognized for its diversity and depth of topics. Access to the SMTH BBS was restricted to on-campus IPs since March 16, 2005, effectively blocking away a substantial portion of its contributors, ranging from graduates living overseas to students from other universities in China. A small protest was held at elite university against tightening government censorship on the Internet. Early in 2006, the SMTH BBS reopened itself to the alien IPs from outside Tsinghua University, available to those who would confirm their identification using a valid email account. However, a large number of its discussion groups are still under tight control, refusing visits from the outside world.

1995 In early August 1995, ace set up a BBS site on a Linux/i386 machine in one of the laboratories of the Tsinghua University. Later, ming and lucky joined the endeavor and transferred the system onto a Sun SPARCstation 20 with 64M memory. On August 8, the BBS formally declared open, and was named "Shui Mu Tsing Hua", often abbreviated as SMTH, which in Chinese means "Water is clear, with trees in florescence", referring to a line in an ancient poem and an actual site in Tsinghua University. The IP address then was 166.111.1.11. In October, SMTH started to provide MUD service. Since November 27, SMTH was accessible through a service of World Wide Web (WWW). At the end of 1995, the number of the registered users at SMTH reached around several dozen.

1996 Between March and April, the SMTH community organized a kite-flying party and received a large publicity nationwide as CCTV (China Central Television) recorded and aired the event in its Our Generation program. SMTH was accessible to the entire campus community around the end of April and saw its traffic peaked. The number of online visitors often ran to the triple digits. September 18, 1996, radical opinions regarding Diaoyu Islands (as known in China, Senkaku Islands as known in Japan) issue appeared on many BBSes across China. The government reacted by closely monitoring these BBSes. Two sites in Peking University were temporarily shut down. SMTH was closed for one day. The following month, SMTH closed its Military, History, Salon and Time-Space Report discussion groups. At the end of October, a new system named FireBird BBS replaced the former one. Before that, the system administrators did a massive overhaul on the original Firebird system. In November, the second version of the WWW-BBS architecture was implemented. In December, SMTH experienced a severe hard drive breakdown, resulting in the loss of two months worth of information.

1997 In January, having recovered from its hard drive failure, SMTH reopened without WWW access. At the same time, Tsinghua University BBS Regulations came into effect. At the end of February, due to the death of Deng Xiaoping, SMTH was temporarily closed. It reopened again on the third of April, with its IP address changed to 202.112.58.200. Late June, the SMTH community launched a fund-raising campaign for a student who fell seriously ill. Late September, the SMTH BBS administration was established and began its first term. SMTH's management and maintenance became regularized.

1998 On March 4th, SMTH was again closed during the period when both the National People's Congress and the Chinese People's Political Consultative Conference were on session. It reopened on April 1. In June, the site experienced another scheduled shut-down. When it was online again on June 15, users organized an offline get-together, a party they called happy98. On December 9, in the atmosphere of the Asian Games, SMTH created a temporary discussion group devoted to the news and analysis of the event, setting a precedent example for all major sports events to follow.

1999 On May 8th, the US attacked Chinese embassy in Yugoslavia. Many users simultaneously expressed their disdain on SMTH, causing a surge in the site's traffic. On December 18th, SMTH acquired the domains smth.org and smth.edu.cn.

Worked examples

Example 1 — a first encounter with SMTH BBS

Start with the simplest possible case. Write down what SMTH BBS claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to SMTH BBS before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about SMTH BBS ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of SMTH BBS

In research
SMTH BBS appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses SMTH BBS in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
SMTH BBS is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bulletin board systems, Internet in China, Tsinghua University, so understanding it makes those chapters shorter.
In everyday life
Look for SMTH BBS outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Why does SMTH BBS matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study SMTH BBS?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
