Wikipedia:Articles for deletion/Unsolved problems in chemistry

Unsolved problems in chemistry

Such a page is inherently PoV. Who decides that a problem is "unsolved"? Who decides that a "problem" is a "problem"? If this page is kept, I would wish to add "Why doesn't Physchim62 earn enough?" as the greatest unsolved problem in chemistry... Physchim62 (talk) 09:35, 30 May 2007 (UTC)[reply]

Professional scientists can decide what a great unsolved problem is. Just look in the literature. Some common sense is also needed. Certain colleges even spend parts of their courses talking about what the unsolved problem are in disciplines such as physics and chemistry. It helps to establish what we know and we don't know and what type of new research is required in the future. Heliumballoon 17:41, 30 May 2007 (UTC)[reply]

The unsolved problems in chemistry page suffers from exactly the same problems as the unsolved problems in biology page, which is currently nominated for deletion (see Wikipedia:Articles for deletion/Unsolved problems in biology (2nd nomination).

The mere concept of "unsolved problems" does not really apply for chemistry. Famous single unsolved problems exist in the formal sciences like mathematics (see unsolved problems in mathematics) and in the applied sciences. For natural science, the "unsolved problems" are hidden in -and dictated by- the respective objects of study and nature.

The resulting lack of criteria for inclusion has resulted in an accumulation of randomly selected and often minor chemical topics, vague questions, non-chemistry topics, already or partly solved problems, pseudoscientific problems, and problems that could never be solved by scientific methods. The current version is a good example for that and the mentioned problems are obvious for any biologists or chemists. While readers who are not experienced in this field might find that collection interesting, it is not the purpose of an encyclopedia to keep purely entertaining articles (beside those eye-catchers on the main page).

An introduction into chemistry topics and an impression about research in this field is already given by our chemistry article the respective subdisciplines linked from there. A complete list of all possible chemical topics would not be useful and is beyond an encyclopedic article. A random selection of topics would be inherently biased and would thereby violate Wikipedia:Neutral point of view and, perhaps, Wikipedia:No original research. It is also immanently impossible to find reliable sources for a certain selection or inclusion, see Wikipedia:Reliable sources.

Also judging from the contents on this page during the past years, this article is not manageable and can never become an encyclopedic article and should be deleted (the only alternative to deletion would be a precise definition of what belongs into this article and what not, but after thinking about this for a long time now, I could not come up with one).

Comment - While this information is not cited, if it is valid, it could be potentially quite useful, and would be useful to someone. It seems a waste to simply delete. --R e m i 10:18, 30 May 2007 (UTC)[reply]
Strong Keep - there is consensus about this is scientific journals and textbooks. It also helps to define what new areas chemistry is exploring. Heliumballoon 10:49, 30 May 2007 (UTC)[reply]

Comment. I am still not sure if you can imagine (after being here for only 14 days and 36 edits mainly in edit wars and policy discussion), how difficult it is to keep articles manageable if there is not the slightest agreement on what belongs there and what not. The big problem is that there is not any agreement on what makes a notable "unsolved problem in chemistry". But feel free to provide reliable sources to back up your claim.

Comment Alas my username is so young and tender and so wet behind the ears..... Here are some specific peer reviewed articles that talk about an "unsolved problem" in chemistry. Defining the frontiers of science is something scientists do all the time and is very useful to know - surely worthy of inclusion in an encyclopedia.

1. Science magazine devoted a whole issue to 125 unsolved puzzles and questions. First 25 [1] Next 100 [2] Here are a few that are relevant to chemistry. What is the structure of water? Researchers continue to tussle over how many bonds each H2O molecule makes with its nearest neighbors. What is the nature of the glassy state? Molecules in a glass are arranged much like those in liquids but are more tightly packed. Where and why does liquid end and glass begin? Are there limits to rational chemical synthesis? The larger synthetic molecules get, the harder it is to control their shapes and make enough copies of them to be useful. Chemists will need new tools to keep their creations growing. Can we predict how proteins will fold? Out of a near infinitude of possible ways to fold, a protein picks one in just tens of microseconds. The same task takes 30 years of computer time.
2. [3] CHEMISTRY: Polymers Without Beginning or End Tom McLeish (20 September 2002) Science 297 (5589), 2005. [DOI: 10.1126/science.1076810] "Natural polymer molecules dominate biology, while artificial polymers are used as plastics or emulsifiers in countless modern products. Many characteristics of their crystalline, glassy, and fluid states can be traced back to the special properties generated by the ends of the molecules. But what would happen if there were no ends? What would be the properties of polymers composed entirely of closed loops?.......The new polymers may not immediately result in new, competitive products, but they stand every chance of clarifying some unsolved puzzles of polymer science.
3. [4] Chemistry: Enhanced: Putting Molecules Behind Bars Steven C. Zimmerman (25 April 1997) Science 276 (5312), 543. [DOI: 10.1126/science.276.5312.543] One of the most fundamental unsolved problems in chemistry is predicting, based solely on its molecular structure, how a molecule will pack in the solid state....
4. [5] presented here [6] Unsolved Problems in Nanotechnology: Chemical Processing by Self-Assembly - Matthew Tirrell - Departments of Chemical Engineering and Materials, Materials Research Laboratory, California NanoSystems Institute, University of California, Santa Barbara. The title of this paper says it all. It was presented at the department of Chemical Engineering at The Ohio State University - Centennial of the Department’s founding - April 24-25, 2003 Heliumballoon 17:12, 30 May 2007 (UTC)[reply]

Commment- If this is kept, there should be some other inclusion-criterion. Should any little problem be inclduded? What makes a problem "large enough" that it merits a mention on this list? At the cutting-edge of any dicipline there will be a near-infinite amount of unsolved problems. Some of these will be solved after being "unsolved" for only a short period of time, since the reason they are unsolved are more because they are NEW problems than DIFFICULT problems. Only including problems that have been unsolved for say, five years, will give the list greater stability, but the number of unsolved problems will still be too large, I think, to include them all. My vote therefore must be delete in its current form, or keep with more restricitive and less arbitrary inclusion criteria.Dr bab 11:39, 30 May 2007 (UTC)[reply]
Strong delete. This will never become an encyclopedic article, it is not manageable, not the slightest clue and agreement exists for inclusion (and exclusion) criteria, the list title is a misconception about the nature of chemistry, and it violates many Wikipedia policies (see nomination).

strong keep as per heliumballoon. clearly mentions why this is notable and verifiable. in addition, i don't see why this editor's particular edit history or time with wikipedia has anything to do with the validity of their vote or argument. i'm CERTAIN after reading numerious writings by Jimbo Whales about how this is a democratic community that is entirely out-of-line. In the U.S., your vote doesn't count any less just because you're 18. Kudos to heliumballoon on responding very well and good-naturedly to it, but I still think it was out-of-line.

- Comment. It is interesting how this discussions attracts voters that have been around for only a week and that have not made a single article edit. Cacycle 20:12, 30 May 2007 (UTC)[reply]
