... Formulas are very similar to equations. Consider for now only equations with one unknown variable , denoted by some letter, which can be x but can also be different. An equation is an equality between two mathematical expressions containing the unknown number (maybe in several places), as well as other numbers which are known. ... For instance--if you multiply two sides of a formula by the same number, the result is still a valid formula, even if what you multiply contains unknown numbers. ...

Storm) Sudden Commencements ( ssc ) are defined by an abrupt increase or decrease in the northward component of the geomagnetic field, which marks the beginning of a geomagnetic storm or an increase in activity lasting at least one hour. ... Before January 1966 these reports were published periodically in Journal of Geophysical Research. ... Beginning with December 1970, these data are published monthly and, thus, are based on fewer reports and differ slightly from similar data published previously. ...
