Sinossi

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In physics, the fine-structure constant is a fundamental physical constant, namely the coupling constant characterizing the strength of the electromagnetic interaction. The numerical value of α is the same in all systems of units, because α is a dimensionless quantity. As of 2008, the best determination of the value of the fine- structure constant is α = 7.297352569(5)×10−3 = 1/137.035999084(51). The standard error is enclosed in parentheses.
