I had to summon a good deal of courage to take a student who had been studying
cube root and "banking and discount," and explain to him that the wisest thing for him to do first was thoroughly master the multiplication table.
He had seen too much of life, and his mind was too matured, to be wholly content with fractions,
cube root, parsing, and analysis; and there were times when their conversation turned on other themes - the last poetry he had read, the latest poet she had studied.
This is very close to 2, so can it be improved without resorting to a calculator or using the 19th century method of finding the
cube root of a number (Hutton, 1846, p.62).
Actual
cube root to nine decimal places is: [cube root of 285.33] [approximately equal to] 6.583383361
Mr Thomas said he was also studying how to calculate the
cube root of 18-digit numbers mentally.
Visually, the most fascinating is the TIX LED Clock [$49.95] from
Cube Root. Containing no hands or digital displays, this fascinating dock simply has four blocks of LEDs that flash in a series of semi-random patterns.
According to John Abruzzo, vice president of LZA Technology, a subsidiary of the Thornton Tomasetti Group whose specialty is analyzing and mitigating the effect an explosion will have on a structure, the force a blast applies on an object is diminished by the
cube root of the increase in distance between that object and the source of the explosion.
After log transformation, KS = 0.072 (P <[10.sup.-118]), after square root transformation, KS = 0.053 (P <[10.sup.-61]), and after
cube root transformation, KS = 0.030 (P <[10.sup.-18]).
Given Stevens' declaration of a "
cube root law" for visual response, and duPlessis' statement that recognition uses visual memory cues, one might wonder if recognition is in some way associated with a cube-root function.
