It is made of three valence quarks (and a jumble of virtual quarks and gluons also) and so has a definite non-zero size.The Astronomisthttps://www.blogger.com/profile/17959972471002184287noreply@blogger.comtag:blogger.com,1999:blog-9633767.post-53759652966554596602010-07-26T17:23:14.122-07:002010-07-26T17:23:14.122-07:00I think QM regards all particles as point particle...I think QM regards all particles as point particles. Otherwise you run into paradoxes such as a point on the circumference of a finite-sized electron moving at several times the speed of light.Wavefunctionhttps://www.blogger.com/profile/14993805391653267639noreply@blogger.comtag:blogger.com,1999:blog-9633767.post-90268326619197366602010-07-21T19:03:44.819-07:002010-07-21T19:03:44.819-07:00I realize that one can't simultaneously measur...I realize that one can't simultaneously measure position and velocity to desired degrees of accuracy. But, quantum mechanics is silent about size apparently. The proton is pretty small. Isn't there some sort of uncertainty principle about size measurement? <br /><br />LuysiiAnonymousnoreply@blogger.com
