| 11. | Similarly, a number known as the fine structure constant characterizes the strength of electromagnetic forces.
|
| 12. | The quantity is the structure constant of the particular gauge group, defined by the commutator
|
| 13. | One such dimensionless physical constant is the fine-structure constant.
|
| 14. | A somewhat damaging statement in his defence of these concepts involved the fine structure constant, ?.
|
| 15. | It is possible to define a unitless fine structure constant for electromagnetism, weak, and strong interactions.
|
| 16. | We can deduce that the structure constants are antisymmetric in the first two indices and real.
|
| 17. | The Universal Gravitational Constant and the Fine Structure Constant are the two that are most often questioned.
|
| 18. | Where \ alpha is the fine-structure constant.
|
| 19. | This brings the structure constants into line with those of the rotation group SO ( 3 ).
|
| 20. | The structure constants C ^ { abc } quantify the lack of commutativity, and do not vanish.
