The MAA has "a list of books recommended by the Association for purchase by college and university libraries". Where are the lists for topics other than math? I know many universities have lists of their course books online, but those aren't that comprehensive. -- 83.84.137.22 ( talk) 00:43, 15 February 2013 (UTC)

I am not familiar with the usages that prevail in medical journals. When an article published in the New England Journal of Medicine reports conclusions of a statistical analysis of data, without explicitly giving the data itself, does the journal provide access, via the web or otherwise, to the actual data?

Hi,
I would like to know why in different heights only the ears feel the pressure, and not some other organs.

Hi,
I would like to know what is the difference between a Fjord and a Gulf?

Note that the tern "fjord" is a technical term used by geographers, but in general speech specifically refers to these features in Scandinavia. In Scotland, they are generally called " sea lochs", an example is Loch Goil, and in the rest of the English speaking world (someone will correct me if I'm wrong about this) " inlet" is used, an example is Burrard Inlet in Canada. However, because these are general terms, they are sometimes applied to features that are not technically fjords. Alansplodge ( talk) 11:42, 16 February 2013 (UTC)
I started the article Splitter plate (aircraft) thinking I knew I how they worked, otherwise I wouldn't have started the article, but looking for citations on the net has led me to doubt my understanding of the topic. I had thought that what the splitter plate did in supersonic flight was that in breaking up the boundary layer air, it tipped turbulent air into the stream of air entering the intakes creating an air dam that slowed the ingested air sufficiently that a simple pitot intake, without the need for intake ramps or inlet cones, was sufficient to insure air entering the engine was within its operational range. Am I very mistaken? One source I found stated that the purpose of the splitter plates was to prevent slow boundary layer air entering the intakes since the engine would work at their most efficient by maximising the intake of fast travellin free air. I know that these things are compromises and trade offs, are different effects at play at different speeds/altitudes -- KTo288 ( talk) 14:42, 15 February 2013 (UTC)
... the thickening of the boundary layer that develops at high angles-of-attack along the lower side of the fuselage forebody [in the F-16]. In order to prevent low-energy flow from entering the engine, the intake had to be offset from the fuselage to free it from the boundary layer, which uninterruptedly passes along the fuselage. The intake cowl [of the F-16] features a moderately blunt lower lip that transitions into a sharp leading-edge extension or splitter plate on the upper side (close to the fuselage).My bold-italic emphasis -- Senra ( talk) 20:32, 15 February 2013 (UTC)
Is the following the correct equation to use to find the entropy generation when iron is quenched?
S(water)= mclnT/T S(iron) = mclnT/T Total S generated = S(water) + S(Iron)

I know that dS=(Q/T)out - (Q/T)in + S(produced in the system). But how do you find dS so that you can find S(produced in system). For some reason my calculation works if I set dS to 0 but I don't know why. My system is a building wall and I calculated the entropy generated by it given the temps outside and inside, it's conductivity & convection heat transfer coefficients from wall to environment and wall to inside. Why is dS 0? Clover345 ( talk) 19:04, 15 February 2013 (UTC)
