A renaissance in how to understand and use quantum mechanics is propagating through many areas of physics. Surprisingly elementary issues are getting new attention via code words such as "Entanglement" and "Quantum Tomography." There are new ways to think about quantum mechanics from the bottom up, which clear away mysteries traditionally thought to exist at the top. By going back to the basics, supposedly advanced experiments and calculations in quantum chromodynamics can be understood by anyone. This leads to highly efficient theoretical and experimental procedures that bypass model-dependent assumptions and unnecessary theoretical superstructure. We illustrate applications with practical quantum tomography of high-energy Z-boson data from the Large Hadron Collider. Analysis discovers a totally unexpected correlation of spin and momentum that is arguably more spectacular than the Stern-Gerlach experiment. At least, that's how we see it!
