what is the use of black box?; it is used by aeroplanes to record information incase of crash people have something to find to see all the data and the outside of the box is made from a hard plastic incase on air-plane crash into water (beacause the black box is made with-stand high pressure water depths) also the box is made to float so it pops to the top of the water when a plane does have a crash into the middle of the sea. thats all i know. hope it was helpful.
The 'Common Uses' section includes many examples that are irrelevant to "black box systems" These should be transferred to the disambiguation page at Black box (disambiguation)
I think that this page should focus more on Black Boxes as they are originally stated that is a device or system where the impute and output are known but the inner workings are unknown. This can be anything from a Search Engine or Taco Bell fast food. In response to my changes sounding like a conspiracy I do believe that our reliance on search engines should be looked at but that it is not really a conspiracy.

- I agree that this article should concentrate on the usage as stated in the definition in the lede, the article needs to be about something identifiable, not a dicdef of every conceivable meaning of the phrase. I also think it should concentrate on the technical usage (again as stated in the lede) as applied in science and engineering (no Taco Bells please, whatever they might be). I don't think that it will be possible to remove the aviation "black box" to the dab page because dab pages cannot have chunks of description on them nor can the entry have multiple links (I see someone has reverted it already). Besides, even though the flight recorder article says they are called black boxes for a different reason, ironically, they are a pretty ideal example of a black box in our meaning; in that it is of no concern how the recording is actually made.

- At the very least, I'm moving the flight recorder reference to the end of the list of common uses; then maybe it won't reappear as the leading instance, contrary to the lede. Also going to use some of SpinningSpark's explanation here on the talk page in that bullet. Benmiller314 (talk) 16:07, 10 February 2010 (UTC)
Word has it that a magic healing machine by Abrams called the oscilloclast was named a black box. This tool was used to heal patients on a distance with some sort of waves (compare bioresonance), the waves were obtained by some other weird tool. When opened the machines' internals consisted of nothing more than wires connected to lights and buzzers. A typical black box if you ask me! See: http://en.wikipedia.org/wiki/Albert_Abrams#Debunking and a source for this claim would be  Williams, William F. (2000). Encyclopedia of Pseudoscience (Facts-on-File) but I do not have access to this book myself. Arakrys (talk) 15:55, 13 November 2009 (UTC)
Use in cybernetics
The reference given is to the preface of Norbert Wiener's second edition of 1961. The first edition of 1948 does not have a preface, and doesn't have an index either, but I think does not mention the term 'black box'. On the other hand, Ross Ashby's An introduction to cybernetics of 1956 has a whole chapter on the black box (chapter 6). The whole treatment is extremely interesting, and for our purposes I think it is the prime reference for 'black box' in cybernetics. Macdonald-ross (talk) 11:57, 25 August 2014 (UTC)
Importance of this article
See this article traffic statistics (normal-average 650 pageviews) and compare with System's article normal-average 1200 pageviews, and Flight recorder's normal-average 300 pageviews. It is more important than the flight recorder, and have only a half of system pageviews.
PS: can anybody "transcribes" this draft-JPEG into a good SVG?
- What are the key features of that diagram that the existing diagram in the article does not have? I can create an svg, but I am not inclined to do the work just for aesthetic reasons. There's always Wikipedia:Graphics Lab. SpinningSpark 21:57, 12 October 2014 (UTC)
- The "clean style" of File:Blackbox.svg is good (!), I think it is more a didactic question, illustrating a "cuboid box" have some appeal.. There are a lot of misconceptions and mistakes about black boxes (see Flight_recorder#Terminology), and I imagine that a an alternative 3D illustration can be used in some other articles to show introduce the backbox. Example: a blackbox (thumb) illustration can also be used in open system and flight recorder. --Krauss (talk) 11:05, 19 October 2014 (UTC)
