1. Cosmic ray muons have been used in an attempt to discover hidden burial chambers in Egyptian pyramids, in much the same way that x rays are used to discover internal imperfections in a metal casting caused by gas bubbles. Why were muons used?
2. Are there any particles other than neutrinos and antineutrinos which have definite heli-cities? Explain.
