Talk:Plateau's laws

Soap films are made of entire smooth surfaces.
What exactly does that mean? A soap film is made of an 'entire' smooth surfaces? Is that part of a soap film, or an entire soap film? What is the difference between entire smooth surfaces and smooth surfaces which are not 'entire'?

Exact or about the tetrahedral angle
Text says 4 borders meet at the tetrahedral angle, Image caption adds "about". Which is it ? - Rod57 (talk) 11:41, 9 October 2022 (UTC)


 * Perhaps the "about" is meant to point out the distinction between theory and reality; how does gravity, for example, affect the angles? But I agree that "about" is not helpful here. —Tamfang (talk) 18:39, 9 October 2022 (UTC)
