TBR: Math Wording?
Are these statements equivalent:
1) X must be increased by a factor of 2/3
2) X must be decreased by a factor of 2/3
Let X = 100.
I interpret statement 1 to be: 100 * 2/3 = 66.7 (for example, increasing something by a factor of TWO means you double it)
I interpret statement 2 to be 100 / (2/3) = 150 (for example, decreasing something by a factor of TWO means you halve it)
TBR claims these statements are the same (TBR Physics Book II page 152 #4).
