Game 3 is over and JOSHUA KREITZER has made a late charge to win!
Hearty congratulations, sir.
> ** Game 3, Round 9 - Miscellaneous - Symbols
> Please see the handout at:
>
http://www.eskimo.com/~scs/msb/3-9/sym.png
> In each case we will name a symbol or describe what it means,
> and you must give us its number on the handout.
This was the easiest round in the original game.
> 1. The square root of -1.
#5. 4 for everyone -- Erland, Dan Blum, Bruce, Calvin, Dan Tilque,
Pete, and Joshua.
> 2. Octothorpe.
#1. Of course it has other names too. 4 for Erland, Dan Blum,
Bruce, Calvin, Dan Tilque, and Joshua.
> 3. Tilde.
#16. 4 for everyone.
> 4. Null set (in set theory).
#13. 4 for Erland, Dan Blum, Dan Tilque, Pete, and Joshua.
2 for Calvin.
> 5. Infinity.
#2. 4 for everyone.
> 6. Euro (currency).
#18. 4 for everyone.
> 7. Ellipsis.
#20. 4 for Erland, Dan Blum, Bruce, Dan Tilque, Pete, and Joshua.
> 8. Indicates that two triangles are congruent (in geometry).
#6. 4 for Erland, Bruce, and Joshua. 2 for Calvin.
When I learned about congruence, the symbol for it was one that's
not on the handout -- instead of the tilde-like upper element, it
has a third horizontal bar. And I wasn't the only one: this question
drew some complaints in the original game. According to Wikipedia,
that symbol is more common in the UK while the one on the handout
is more common in the US. (And since both are used, I decided to
leave the question alone when posting it here.)
In Unicode the symbol on the handout has hexadecimal value 2245 and
is named "approximately equal to", which is another of its meanings.
(Still another meaning, according to
mathworld.wolfram.com, is
"isomorphic to".) For the meaning "approximately equal to", the lower
bar is more commonly omitted, making Unicode 2243, which Unicode calls
"asymptotically equal to", or else two of the tilde-like elements are
used with no straight bar, making Unicde 2248, which Unicode calls
"almost equal to". The triple bar that I learned for congruence is
Unicode 2261, which Unicode calls "identical to". For the Unicode
symbols and names see:
http://unicode.org/charts/PDF/U2200.pdf
Wotta mess.
> 9. Factorial (in math).
#4. 4 for everyone.
> 10. Used in the German language to represent a double S or "sz"
> sound, for example replacing the "ss" in "Strasse" (street).
#8. 4 for everyone.
The form ß is only used in lower case, and only in Germany and Austria
(of the four predominantly German-speaking countries); Straße becomes
STRASSE when written in block capitals, and Strasse in Switzerland
and Liechtenstein, as you can verify by looking at street signs in
Google Street View.
> The organizers did not provide a list of the other symbols shown,
> but I will. If you want to identify them for fun, but for no points,
> decode the following rot13:
> 11. Square root.
#10. Erland, Bruce, and Joshua got this.
Historically at least, the horizontal bar is a vinculum serving like
parentheses to group the operand, and not part of the square-root
symbol, Unicode 221A. The bar might be omitted when the operand is
a simple expression such as a number or a variable.
> 12. Japanese yen.
#3. Erland, Bruce, and Joshua got this.
> 13. Ratio of a circle's circumference to its diameter (in geometry).
#11. Erland, Bruce, and Joshua got this.
> 14. Indicates summation of a series (in math).
#7. (Unicode 2211, named "n-ary summation".) Erland, Bruce,
and Joshua got this.
> 15. "Is a proper subset of" (in set theory).
#14. (Unicode 2282, named "subset of".) Erland and Joshua got this.
> 16. Indicates integration (in calculus).
#9. (Unicode 222B.) Erland, Bruce, and Joshua got this.
> 17. Therefore (in math).
#19. (Unicode 2234.) Erland, Bruce, and Joshua got this.
> 18. "Is proportional to" (in math).
#12. (Unicode 221D.) Erland and Joshua got this.
> 19. British pound (currency).
#17. (Also used for some other currencies with similar names.)
Erland, Bruce, and Joshua got this.
> 20. The set of integers.
#15. Erland and Joshua got this.
> ** Game 3, Round 10 - Challenge Round
> * A. Quiz Show Scandals
> A1. Charles Ingram was found guilty of cheating on a certain TV
> quiz show by having a member of the audience send him signals
> by coughing. Give the title *and* name the country where
> the show was produced.
"Who Wants to be a Millionaire", UK version. 4 for Calvin and Joshua.
> A2. In the 1950s a TV quiz-show contestant named Charles
> Van Doren was seen to obtain unusually high scores.
> He eventually admitted he had been given information by the
> producers to prepare before the show -- they wanted to keep
> him on the air because he was quite photogenic. What show?
"Twenty-One". (These events were fictionalized in the 1994 movie
"Quiz Show".) 4 for Joshua.
> * B. Cold War Invasion Attempts
> B1. In the early 1960s the US sent a number of combatants into
> Cuba in an attempt to overthrow the Castro regime. In fact
> they were rapidly captured by the Cuban authorities.
> How is this incident usually referred to?
The Bay of Pigs. (From the Bahía de Cochinos, where they landed.)
4 for Erland, Dan Blum, Calvin, Dan Tilque, Pete, and Joshua.
> B2. In the late 1940s the US and the UK sent a number of
> combatants into *this* country in an attempt to overthrow
> *its* Communist regime. In fact they were rapidly captured.
> It later emerged that their spy in Britain, Kim Philby,
> had tipped off the Soviets to the correct time and place.
> In which country was this failed attack?
Albania. 2 for Calvin.
> * C. Sports Competitions
> C1. The Ryder Cup golf tournament takes place every two years --
> always between which two teams?
United States vs. Europe. 4 for Erland, Bruce, Calvin, Dan Tilque,
and Pete.
Originally it was the US vs. Great Britain, but the US came to
dominate it to such an extent that the format was changed.
> C2. The Ashes is a test cricket series between two countries,
> which emerged out of a resounding victory in 1892 of one
> of them over the other. Which two countries play?
England (not UK) vs. Australia. 4 for Erland, Calvin, Pete,
and Joshua.
> * D. City Centers
> D1. What type of geographical feature is at the center of the
> Hanoi Capital Region?
A lake. 4 for Erland and Pete. 2 for Calvin.
This was the second Hanoi question in this game. The first one was
in the current-events round and only asked what country Trump was
going to meet Kim Jong Un in, but the specific city was Hanoi.
> D2. In the center of Milan are many shops and restaurants,
> the cathedral known as the Dome, and which famous opera
> house?
La Scala. 4 for Erland, Dan Blum, Calvin, Pete, and Joshua.
> * E. Nuclear-Weapon Physicists Called Disloyal
> E1. Name the US physicist who, with General Groves, headed up
> the development of the atom bomb during the Manhattan
> Project. After the war his security clearance was revoked
> due to his association with left-wing individuals.
Robert Oppenheimer. 4 for Dan Blum, Bruce, Calvin, Pete, and Joshua.
> E2. Name the Soviet physicist who helped his country develop
> the hydrogen bomb in the 1950s. A dissident and
> human-rights activist, he was exiled to the city of Gorky
> after criticizing the invasion of Afghanistan.
Andrei Sakharov. 4 for Erland, Dan Blum, and Joshua.
> * F. Relatives
> F1. Germany physicist Max Born contributed to quantum mechanics
> by studying the probabilistic aspects of the theory --
> but never mind that, these are not the physicist questions.
> Just name his famous *granddaughter*, who was born in Wales
> but moved at an early age to Australia.
Olivia Newton-John. 4 for Calvin and Joshua.
> F2. British actor Anthony Booth played the role of Warren
> Mitchell's son-in-law on the British TV series "Till Death
> Us Do Part" -- but these are not actor questions either.
> Booth had a very famous *son-in-law*: who?
Tony Blair. 4 for Calvin and Joshua.
