[RASMB] Frictional ratio of two touching spheres

[Arthur Rowe]

. . . . and José's computation for 2 touching spheres is f/f0 = 1.06.

{just in case there should be anyone out there who does not have a copy of
the Harding, Rowe & Horton eds (1992) book immediately to hand!}

Hi RASMBers,

There is also Jose Garcia de la Torre's chapter in the 1992 book
"Analytical Ultracentrifugation in Biochemistry and Polymer Science"
has some values for various shaped oligomers of spheres.
