Dihydrogen monoxide parody story has since been used in science education to encourage critical thinking and discussion of the scientific method. A 1983 April Fools' Day edition of the "Durand Express", a weekly newspaper in Durand, Michigan, reported that "dihydrogen oxide" had been found in the city's water pipes, and warned that it was fatal if inhaled, and could produce blistering vapors. The first appearance of the parody on the Internet was attributed by the "Pittsburgh Post-Gazette" to the so-called "Coalition to Ban Dihydrogen Monoxide", a parody organization at UC Santa Cruz following on-campus postings and newsgroup discussions in 1990.

Equivalent oxide thickness Equivalent oxide thickness An Equivalent oxide thickness is a distance, usually given in nanometers (nm), which indicates how thick a silicon oxide film would need to be to produce the same effect as the high-κ material being used. The term is often used when describing field effect transistors which rely on an electrically insulating pad of material between a gate and a doped semiconducting region. Device performance has typically been improved by reducing the thickness of a silicon oxide insulating pad. As the thickness approached 5–10 nm, leakage became a problem and alternate materials were necessary to increase the thickness
