Frequencies Not Expressed in Hertz
Even higher frequencies are believed to occur naturally, in the frequencies of the quantum-mechanical wave functions of high-energy (or, equivalently, massive) particles, although these are not directly observable, and must be inferred from their interactions with other phenomena. For practical reasons, these are typically not expressed in hertz, but in terms of the equivalent quantum energy, which is proportional to the frequency by the factor of Planck's constant.

Famous quotes containing the word expressed:
“[F]rankly ... it was perfectly true that I had, for over a year, expressed the opinion that Indo-China should not go back to France but that it should be administered by an international trusteeship. France has had the country ... for nearly one hundred years, and the people are worse off than they were at the beginning.... France has milked it for one hundred years. The people of Indo-China are entitled to something better than that.”
—Franklin D. Roosevelt (1882–1945)
