ICBM address

ICBM address is a science 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 ICBM address rather than just read about it. In short: ICBM (intercontinental ballistic missile) address or missile address is hacker slang for one's longitude and latitude (preferably to seconds-of-arc accuracy) when placed in a signature or another publicly available file. Origin The form that used to register a site with the Usenet mapping project, before Internet connectivity became commonplace for Usenet sites, included a field for longitude and latitude, preferabl…

Key takeaways

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

Reference excerpt

ICBM (intercontinental ballistic missile) address or missile address is hacker slang for one's longitude and latitude (preferably to seconds-of-arc accuracy) when placed in a signature or another publicly available file.

Origin The form that used to register a site with the Usenet mapping project, before Internet connectivity became commonplace for Usenet sites, included a field for longitude and latitude, preferably to seconds-of-arc accuracy. This was actually used for generating geographically correct maps of Usenet links on a plotter; however, it became traditional to refer to this as one's ICBM address or missile address, and some people include it in their sig block with that name. A typical tag might read "ICBM Address: 36.8274040 N, 108.0204086 W".

Modern use Today, using the ICBM method of coordinates is one method of geotagging webpages or other online material. Some projects parse ICBM address included in webpages via meta tags, which can then be used to map out sites added to its database. Web page uses of <meta name="ICBM" content="12.345, 67.890"> specify the same location as a geo:12.345,67.890 URI.

Worked examples

Example 1 — a first encounter with ICBM address

Start with the simplest possible case. Write down what ICBM address claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 ICBM address 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 ICBM address 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 ICBM address

In research
ICBM address appears in science 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 ICBM address 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
ICBM address is common in secondary-school and first-year university syllabi. It links to neighbouring topics Intercontinental ballistic missiles, Internet slang, Metaphors referring to weaponry, so understanding it makes those chapters shorter.
In everyday life
Look for ICBM address 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 ICBM address matter?

Because it connects several science 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 ICBM address?

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.
