Although many people believe that Planck's constant, h, was the first-discovered universal constant, in reality, it follows four others, as explained in Chapter 2. Also, it was invented, not discovered. If you are already acquainted with Planck's constant, no doubt you learned that it is a fundamental, universal physical constant of nature (FUPCON). This description seems to mean that it has existed in nature from time immemorial, and Planck just happened to discover it at the opportune time--during the birth of quantum theory. In reality, he invented it so that he could convert a particular proportion into an equation. Therefore, the term, fundamental, universal physical constant of nature, or FUPCON, is a misnomer for constant of proportionality, which, itself, is a misnomer for collection of quantum-attribute factors.
