Editing Archimedes' principle (section)

==Refinements==

Archimedes' principle does not consider the [[surface tension]] (capillarity) acting on the body.<ref>{{cite web |url= http://www.weizmann.ac.il/home/fnfal/papers/Natfloat.pdf |title=Floater clustering in a standing wave: Capillarity effects drive hydrophilic or hydrophobic particles to congregate at specific points on a wave | date=2005-06-23 }}</ref> Moreover, Archimedes' principle has been found to break down in [[complex fluid]]s.<ref>"Archimedes's principle gets updated".

There is an exception to Archimedes' principle known as the bottom (or side) case. This occurs when a side of the object is touching the bottom (or side) of the vessel it is submerged in, and no liquid seeps in along that side. In this case, the net force has been found to be different from Archimedes' principle, as, since no fluid seeps in on that side, the symmetry of pressure is broken.<ref>{{Cite journal |title=Using surface integrals for checking the Archimedes' law of buoyancy |journal = European Journal of Physics|volume = 33|issue = 1|pages = 101–113| year=2012 |arxiv = 1110.5264|doi = 10.1088/0143-0807/33/1/009|last1 = Lima|first1 = F M S.|bibcode = 2012EJPh...33..101L|s2cid = 54556860}}</ref>
