In his 1924 thesis, de Broglie conjectured that the electron has an internal clock that constitutes part of the mechanism by which a [[pilot wave]] guides a particle.<ref>See for example the description of de Broglie's view in: David Bohm, Basil Hiley: ''The de Broglie pilot wave theory and the further development and new insights arising out of it'', Foundations of Physics, volume 12, number 10, 1982, Appendix: On the background of the papers on trajectories interpretation, by D. Bohm, ([http://leopard.physics.ucdavis.edu/rts/p298/pilotwavetheory.pdf PDF] {{webarchive|url=https://web.archive.org/web/20110819234038/http://leopard.physics.ucdavis.edu/rts/p298/pilotwavetheory.pdf |date=19 August 2011 }})</ref> Subsequently, [[David Hestenes]] has proposed a link to the [[zitterbewegung]] that was suggested by Schrödinger.<ref>D.

While attempts at verifying the internal clock hypothesis and measuring clock frequency are so far not conclusive,<ref>See for example G.R. Osche, ''Electron channeling resonance and de Broglie's internal clock'', Annales de la Fondation Louis de Broglie, vol.&nbsp;36, 2001, pp.&nbsp;61–71 ([http://aflb.ensmp.fr/AFLB-361/aflb361m718.pdf full text])</ref> recent experimental data is at least compatible with de Broglie's conjecture.<ref>Catillon, Foundations of Physics, July 2001, vol.&nbsp;38, no.&nbsp;7, pp.&nbsp;659–664</ref>
