During this International Year of Quantum Science and Technology, AstroNotes articles will address the importance of quantum to many exciting aspects of astronomy and physics. The principles of quantum physics were laid out a century ago, yet most people still deem quantum beyond understanding. However, instead of avoiding quantum as a topic too impenetrable for introductory courses, we urge teachers to embrace how quantum effects are so amazing and important for understanding the very topics most interesting to students. Besides enjoying the pretty pictures of celestial objects, students care about how quantum
makes it possible for our Sun to shine,
permits us to know what stars are made of,
stops dead stars collapsing,
allows black holes to evaporate,
can be the source of vacuum energy, and
sidesteps our intuition (instantaneous communication, teleportation, etc.).
As teachers, we should take advantage of curiosity regarding quantum effects, assuming that everyone is capable of...
