About the name
“hbar” refers to ℏ — the reduced Planck constant, a fundamental quantity in physics (h / 2π), introduced by Paul Dirac around 1926. It is pronounced “h-bar” and written ℏ (Unicode U+210F). The hbar.* constellation of projects uses this symbol and name because the underlying research is about coherent systems, state evolution, and the mathematics of observation — domains where ℏ is a natural semantic anchor. The name is descriptive of the research, not a commercial brand.
