Across
- 2. It is the name of the scientist who proposed the Dirac equation.
- 6. It is a physical quantity named after a Hamilton physicist.
- 7. It is the concept of linear algebra and a generalization of the intuitive concept of vertical. It makes sense only in a definite inner product space. It is used to represent the case that the inner product of two vectors in the inner product space is 0.
