1. 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.

2. Who, in 1882, proved the transcendence of pi?
Werner Heisenberg
Mark Dettinger
Richard Feynman
Abraham Lincoln
Ferdinand Lindemann

3. One way to calculate the value of pi is to find the perimeter of polygons inscribing and circumscribing a circle. The circumference of the circle lies in between those two values, and the values approach pi as the number of sides of the polygon approaches infinity. Who originated this method of pi approximation?
Archimedes of Syracuse
Plato
Pythagoras
Socrates
Murray Gell-Mann

4. Are pi's digits periodic?
Yes; the digits repeat themselves after every 6000 decimal places.
No; only women, not numbers, are unfortunate enough to be periodic.
Maybe; not enough digits of pi have yet been calculated to know if they start eventually repeating themselves.
Yes; every infinitely long number has to start repeating itself sometime.
No; every periodic number is rational, but pi is irrational.

5. A famous book contains the following paragraph, implying that pi=3:

And he made a molten sea, ten cubits from the one brim to the other: it was round all about, and his height was five cubits: and a line of thirty cubits did compass it about.

What book does this come from?

Homer's Odyssey
Ulysses by James Joyce
The Bible
A Brief History of Time by Stephen Hawking
Douglas Adams' Hitch Hiker's Guide to the Galaxy
