bottom quark[edit]

I think it could be the bottom quark.

  • "age 1000 F": on the page 1 E-12 s, the bottom quark is mentioned with a lifetime of about 1 picosecond = 1000 femtoseconds ('F's)
  • "height 0.009 F": its (size / diameter) could be about 9 x 1 E-18 m = 0.009 femtometers - actually, the size of such a particle is not easy to define: we find that a "quark's size" would be 1 E-18 m (this should be somehow justified there...), but the different quarks are very different in size (mass, at least); on the same page, the proton's size is given as 1 fm, while elsewhere its radius is said to be 2 fm.... but knowing this and that it is composed of 3 quarks (with lots of "vacuum" in-between) this size seems realistic, and I'm sure that in some place one can find this value of 0.009 fm.
  • "weight 2.6497 F": this is the weakest part of my argumentation; in fact its mass is not even "exactly" known, but about 4300 MeV/c² = 8 E-27 kg, which is very far from 2.6497 femtograms ; a much closer relation could be 2.6497 x (mass of an F nucleus) = 8 E-26 kg (wrong by just 1 power of ten...)...
  • Finally, quarks also have colours, but you should not ask for it's colour, since any quark can have any of the three colours...

P.S.: suggested/expected answer: "nice try, but it's not a bottom quark"... :-!

Nice try. ;) What I am looking for is larger than a quark, as the units are not femto-. -- Ravn 09:52, 25 January 2006 (UTC)

FFF[edit]

Searching unit of measurement for something indicated by an "F", I stepped through Imperial Unit, furlong, to the odd unit of furlongs per fortnight. The strange units entry had a table for FFF Base units of length (furlong), mass (firkin), and time (fortnight). Converting to SI:

  • 1000 Fortnights = 38.4 years
  • 2.6497 Firkin = 108.4 kg (239 lbs)
  • 0.009 Furlong = 1.892 m (6.2 ft)

which appear to be describe some 38-year-old people, but Ravn refers to its color in the question's title. I've got to be close, but I have no idea where to go from here. Hoof Hearted 21:25, 25 January 2006 (UTC)

The closest I can find is Chris Romero. Dmn 23:41, 25 January 2006 (UTC)

Doh![edit]

Pounds was the way to go, since it was exact. There are only 6 articles in WP with "239 lbs" - all pro-wrestlers.

However searching for "239 pounds" reveals User:ShutterBugTrekker talking about Homer Simpson. His age is somewhat uncertain, but 38 years lies in the middle of the range. Homer stands at 6 feet (1.83 meters) (I calculate 0.009 furlongs as 1.81m - close enough without going to more sig figures) .

And he is yellow. Dmn 00:09, 26 January 2006 (UTC)

User:ShutterBugTrekker might be interested in the link to 42 on the Wikifun page. Dmn 00:13, 26 January 2006 (UTC)
Congra-diddely-dations. That's the right answer. If I had had to give a hint at some time, I'd revealed that it's FFFF00. ;) -- Ravn 10:37, 26 January 2006 (UTC)
Aha, a practical function of Wikifun! We found an error in the conversion table to which I was referring: 1 furlong = 201.168m, not 210.168m. Hoof Hearted 17:58, 26 January 2006 (UTC)
