This is wrapped up in the phenomenon of CP violation, by which charge and parity are both violated by certain weak interaction processes - this enables antimatter to be unambiguously distinguished from matter, and left handed chirality from right handed.REFERENCESThe Ozma Search for Extraterrestrial Intelligence (SETI) Projecthttps://www.seti.org/seti-institute/project/details/early-seti-project-ozma-arecibo-messageSean Carroll on CP Symmetry (& why we shouldnt trot out baryogenesis all the time)https://www.preposterousuniverse.com/blog/2010/06/04/marketing-cp-violation/Electroweak CP Violation on Scholarpediahttp://www.scholarpedia.org/article/CPviolationinelectroweakinteractionsThe Wu Experimenthttps://en.wikipedia.org/wiki/WuexperimentMartin Gardner, The New Ambidextrous Universehttps://books.google.com/books?id=kdLGa8cPPUC&lpg=PP1&pg=PR2#v=onepage&q&f=falseLecture notes on CP Violation and the CKM Matrix, Cambridge (Mark Thomson)https://www.hep.phy.cam.ac.uk/thomson/lectures/partIIIparticles/Handout122009.pdfHomochiralityhttps://en.wikipedia.org/wiki/HomochiralityL-glucose (vs D-glucose)https://en.wikipedia.org/wiki/L-GlucoseRadioactive Nucleus Decayhttp://www.radioactivity.eu.com/site/pages/RadioactiveSeries.htmCP Violation in Semi-Leptonic Decays (SEE PAGE 426 for reference to definition of MATTER)https://www.hep.phy.cam.ac.uk/thomson/lectures/partIIIparticles/Handout122009.pdfKaon Decay Modeshttp://pdg.lbl.gov/2012/listings/rpp2012-list-K-zero-L.pdfFlipped bowling Jesus scene in Big Lebowskihttps://www.youtube.com/watch?v=lWz8NGIisMoIsotopes of Uraniumhttps://en.wikipedia.org/wiki/IsotopesofuraniumBeta Decayhttps://en.wikipedia.org/wiki/BetadecayThe Wu Experimenthttps://en.wikipedia.org/wiki/WuexperimentKaonshttps://en.wikipedia.org/wiki/KaonCP Violation in Symmetry Magazinehttps://www.symmetrymagazine.org/article/charge-parity-violationPhysics Stack Exchange on CP Violationhttps://physics.stackexchange.com/questions/160511/what-cp-violating-processes-do-we-know-ofMinutePhysics is on twitter - @minutephysicsAnd facebook - http://facebook.com/minutephysicsAnd Google+ (does anyone use this any more?) - http://bit.ly/qzEwc6Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute!Created by Henry Reich
