A mnemonic device is a scheme wh to recall facts by memorizing something completely unrelated to the facts. One way of learning the first few digits of the decimal for a is to memorize a sen- tence (or several sentences) and count the letters in each word of the sentence. For example, "See, I know a digit," will give the first 5 digits of 7: "See" has 3 letters, "I" has 1 letter, "know" has 4 letters, "a" has 1 letter, and "digit" has 5 letters. So the first five digits are 3.1415. Verify that the following mnemonic devices work. (a) "May I have a large container of coffee?" (b) "See, I have a rhyme assisting my feeble brain, its tasks ofttimes resisting." (c) "How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics."

Transcribed Image Text:54. A mnemonic device is a scheme whereby one is able
to recall facts by memorizing something completely
unrelated to the facts. One way of learning the first
few digits of the decimal for 7 is to memorize a sen-
tence (or several sentences) and count the letters in
each word of the sentence. For example, "See, I know
a digit," will give the first 5 digits of 7: "See" has 3
letters, "I" has 1 letter, "know" has 4 letters, "a" has 1
letter, and "digit" has 5 letters. So the first five digits
are 3.1415.
Verify that the following mnemonic devices
work.
(a) "May I have a large container of coffee?"
(b) "See, I have a rhyme assisting my feeble brain, its
tasks ofttimes resisting."
(c) "How I want a drink, alcoholic of course, after the
heavy lectures involving quantum mechanics."
