[Phys-L] Re: Buoyancy question

[clement at HAL-PC.ORG (John M Clement)]

One needs to generalize this a bit to take into account the "floating
needle" on surface tension.  The generalization would take into
account the volume of the surface that has been depressed by the
needle.  This generalization is needed for small objects such as water
skating bugs, but not for battle ships.  Would this be virtual volume,
or pseudovolume, or what?
