These questions were written to be asked in Toronto on 2012-02-27,
and should be interpreted accordingly. All questions were written
by members of Footloose and Firkin Free, but have been reformatted
and may have been retyped and/or edited by me. I will reveal the
correct answers in about 3 days.

For further information, including an explanation of the """ notation
that may appear in these rounds, see my 2021-07-20 companion posting
on "Reposted Questions from the Canadian Inquisition (RQFTCI*)".


* Game 5, Round 4 - Geography - Countries of the World

Please see: http://www.eskimo.com/~scs/msb/05-04/world.pdf

We give you the name of a country and you give the number of the
country's outline. Naturally, the outlines are not all to the
same scale, but all of them show north at the top.

1. Japan.
2. Nepal.
3. Finland.
4. Vietnam.
5. Portugal.
6. Ireland.
7. Hungary.
8. Sri Lanka.
9. Switzerland.
10. Libya.

There were 8 decoys. Decode the rot13 if you'd like to try the
remaining countries for fun, but for no points.

11. Phon.
12. Rtlcg.
13. Senapr.
14. Vfenry.
15. Xraln.
16. Cnxvfgna.
17. Cuvyvccvarf.
18. Fcnva.


* Game 5, Round 6 - Science - The Ancients

1. Around 1200 BC, astronomers from this ancient nation,
considered the birthplace of western astronomy, produced
a series of star catalogues, written in cuneiform script
that contained lists of constellations, individual stars,
and planets. What nation?

2. This branch of mathematics evolved in the third century BC
as a branch of geometry used extensively for astronomical
studies. It is also the foundation of the practical art
of surveying. Name it.

3. Eratosthenes learned that each year on the day of the summer
solstice sunlight reached the bottom of a well in Syene,
Egypt, indicating that the sun was directly overhead.
However, on the same day in Alexandria, he observed that
the sun was at an angle from the vertical -- thus proving
what fact?

4. Eratosthenes, using these same observations, the specific
angle of the sun in Alexandria, and an estimate of the
distance between the two cities, calculated what?

5. Pythagoras of Samos married music and mathematics by proving
that the pitch of a note played on a stringed instrument is
proportional to what?

6. Apply your Pythagorean theorem. In a right-angled triangle,
if one side is 5 inches long and the hypotenuse is 13 inches
long, how long is the other side?

7. Pythagorean mathematicians also discovered a class of
numbers which could not be precisely expressed in the way
that numbers previously had been. The Pythagoreans called
these "unspeakable numbers". What do we call them?

8. Consider the following sums of successive odd numbers: 1+3,
1+3+5, 1+3+5+7, 1+3+5+7+9, and so forth. Pythagoras observed
that the answers form the sequence of what kind of number?

9. Archimedes is reputed to have said "Give me a place to stand
on and I will move the Earth!" His work on what fundamental
principle of mechanics prompted the remark?

10. This philosopher made no astronomical observations
whatsoever, yet his statement that all celestial bodies
must be perfectly spherical and move in perfect circles
at uniform speed became the guiding principle of astronomy
until the 17th century. Name him.

None of these maps have changed.

also here.

Babylonia. 4 for Stephen, Joshua, and Dan Blum. 3 for Dan Tilque.

Trigonometry. 4 for Stephen, Joshua, Dan Blum, and Dan Tilque.

That the Earth is round (or, more precisely, not flat). 4 for
everyone.

> 4. Eratosthenes, using these same observations, the specific

> distance between the two cities, calculated what?

The size of the Earth. 4 for everyone.

The length of the string, or its reciprocal, depending on what
exactly is meant by "pitch" being proportional. (Accepting either.)
4 for Stephen, Joshua, Dan Blum, Pete, and Dan Tilque.

12 inches. 4 for Stephen, Joshua, Dan Blum, and Dan Tilque.
3 for Erland and Pete.

I generously scored the meaningless "12" as almost correct.

Irrational numbers. 4 for Erland, Stephen, Joshua, Dan Blum,
and Dan Tilque.

> 8. Consider the following sums of successive odd numbers: 1+3,
> 1+3+5, 1+3+5+7, 1+3+5+7+9, and so forth. Pythagoras observed

Square numbers. 4 for everyone.

Leverage. 4 for Stephen, Joshua, and Dan Tilque.

"Fulcrum" is a part of a lever setup, not a principle.

Plato. His student Aristotle was also accepted on a protest.
4 for Stephen, Joshua, and Dan Tilque.

Ptolemy, though, *was* an observational astronomer.
