Point particle of point charges cannot be maintained in an equilibrium configuration solely by the electrostatic interaction of the charges. In quantum mechanics, there is a distinction between an elementary particle (also called "point particle") and a composite particle. An elementary particle, such as an electron, quark, or photon, is a particle with no internal structure. Whereas a composite particle, such as a proton or neutron, has an internal structure (see figure). However, neither elementary nor composite particles are spatially localized, because of the Heisenberg uncertainty principle. The particle wavepacket always occupies a nonzero volume. For example, see atomic orbital: The electron
My Name Is 'A' by Anonymous to releasing the film Ryan chose to release the work anonymously due to negative initial critic reviews. At this point the film's title had changed to "My Name Is 'A'" and Ryan added the words "By Anonymous" to the title to reflect on what was supposed to be the anonymity of the director. He later decided against releasing the film anonymously, but chose to leave "By Anonymous" in the title to reflect on the anonymity of several of the characters in the film. Theatrical and VOD film rights to "My Name Is 'A' By Anonymous" were purchased shortly after its
