Pi Flower
1. The following are all mnemonics for remembering the first few digits of pi (the number of letters in each word corresponds to a digit of pi). Which of these was written in 1995 by Michael Keith?
Sir, I send a rhyme excelling
in sacred truth and rigid spelling.
Numerical sprites elucidate
For me the lexicon's dull weight.
Now I, even I, would celebrate
In rhymes inapt, the great
Immortal Syracusan, rivaled nevermore,
Who in his wondrous lore,Passed on before,Left men his guidance
How to circles mensurate.
But a time I spent wandering in bloomy night; Yon tower, tinkling chimewise, loftily opportune.
Out, up, and together came sudden to Sunday rite,
The one solemnly off to correct plenilune.
How I want a drink, alcoholic of course, after the heavy lectures involving quantum mechanics. All of thy geometry, Herr Planck, is fairly hard.
Poe, E. -
Near A Raven

Midnights so dreary, tired and weary,
Silently pondering volumes extolling all by-now obsolete lore.
During my rather long nap - the weirdest tap!
An ominous vibrating sound disturbing my chamber's antedoor.
"This", I whispered quietly, "I ignore".

2. Which of the following is NOT equal to pi?
4 * the integral from 0 to 1 of sqrt(1 - x^2)dx
4 * arctan 1
the ratio of any circle's circumference to its diameter
(3/4) * the number of radians in a 270 degree angle
2 * the number of radians in a right angle

3. Which of the following binary numbers is closest in value to pi:
11.0010010000111111
101.110101000111100
10.0001101010110100
1.10111011010010011
111.010111101011111

4. In 1897 a state House of Representatives unanimously passed a bill setting pi equal to 16/(sqrt 3), which approximately equals 9.2376. In which state of the United States did this occur?
California
Indiana
Massachusetts
Florida
Canada

5. How does one convert pi in base 10 to base 2?
Keep only the '0' and the '1' in the decimal expansion.
It is impossible because pi > 2.
Replace each digit of pi in base 10 with a 0 if it is divisible by 2 and with and 1 if it is not.
Successively multiply pi by 2 and put a '1' when it is greater than 1 and a '0' when it is smaller than 1. Repeat this step after having kept only the fractional part of the result.
Divide pi in base 10 by 5.
