The twentieth century has witnessed a burst of discovery in physics unparalleled in human history. Despite the fact that general relativity and quantum mechanics are well over half a century old, introductory physics classes in high schools, colleges, and universities essentially ignore them. These two seminal ideas, the phenomena of superconductivity (teens), holography and nuclear fission (1940s) nuclear fusion and semiconductor physics (1950s), maser and laser physics (1950s and 1960s), explication of phase changes (1960s and 1970s), gauge theories and QCD (1970s), and unification of cosmology and particle physics (1980s) are all but ignored. Mere mention of these, as well as nuclear magnetic resonance (NMR) and radiotherapy used in medicine, would help to give students a feeling for the diversity and vitality of physics and its attendant technology. A few examples integrating vital fields of physics into a normal curriculum are given. (Author/JN)
