Strangely enough, the performance of Medea is mentioned on page 529 of the Google Books file, which is omitted. You can find the quote mentioned in the tossup on page 530, however. Also, Dan Needham puts on a number of Euripides plays- was that confusing for anyone? Medea is the most emphasized/directly quoted but I was wondering how that would play.Mike Bentley wrote:Here were some of the notes I took during the tournament:
The tossup on Medea starts with a clue from Owen Meany. The only play I remember in that is a performance of A Christmas Carol. Maybe Medea happened in it but I didn't see any references in a Google book search.

Hm. Upon google search, the story clued here maybe isn't that well known? This will probably have to be adjusted, thanks for drawing our attention to it.Packet 7 wrote:14. This group included Maia, the mother of Hermes, and Electra, the mother of Dardanus. For 10 points each:
[10] Name these sisters of the Hyades and the Hesperides. One myth says they committed suicide after the death of their father Atlas, while another claims that they were turned into doves to escape Orion.
ANSWER: the Pleiades
[10] In the creation myth of these people, the Pleiades were the first constellation placed into the sky by Black God. Complaining that the process was taking too long, Coyote used a blanket to throw the rest of the stars into the sky.
ANSWER: Navajo [or Diné bizaad]
[10] In a myth of the Nez Perce, one of the Pleiades pulls the sky over her face after her sisters mock her for falling in love with a man with this trait. The Navajo believed that people gained this trait after Coyote threw a stone into a lake, which sank.

During a production of this play in A Prayer for Owen Meany, Dan Needham emphasizes the line “Many things the gods achieve beyond our judgment” as spoken by a “sorrowful girl.” After being asked “Are not these words of mine pleasing for you to hear?”, a character in this play exclaims “I am lost!” repeatedly.

The title character of this play kills her children and Glauce. For 10 points, name this Euripides play about the vengeful wife of Jason.
ANSWER: Medea
James is right. The lead-in is absolutely not uniquely identifying, and there are plenty of systems with the same normal frequencies. I like the reference to elliptic integrals, but the Legendre and Taylor clues are problematic: anyone who would buzz on Legendre polynomials would have already gotten the question by "elliptic integral", so it doesn't make sense for it to be the power cutoff. Mentioning them before the integral clue probably wouldn't work either, as Legendre polynomials are used all over the place (they're also more common in electrostatics than mechanics). Virtually every non-trivial mechanics problems involves a Taylor expansion, so that clue isn't very useful. It might be better to replace it with something about the small-angle approximation (as overclued as it may be).Packet 2 wrote:16.

I don't actually know anything about this, so I can't say anything, but it seems that it would be helpful to clarify this in the clue – suggestions on how to do that would be appreciated! Also, I should acknowledge here that a commont complaint was the "third sound" cliff in this tossup, which we will also address.Abstract from 'Quantum phase transition from a superfluid to a Mott insulator in a gas of ultracold atoms' wrote:Here we observe such a quantum phase transition in a Bose–Einstein condensate with repulsive interactions, held in a three-dimensional optical lattice potential. As the potential depth of the lattice is increased, a transition is observed from a superfluid to a Mott insulator phase.
Thank you! I'm glad it was enjoyable.Thanks again for writing the set! It was a lot of fun, and I had several delightful buzzes.
I think part of the transparency resulted from the fact that you hear about big business and skyscrapers (window cleaner), which already kinda leads you towards NYC. But do you think that any NYC tossup on musicals will be inherently transparent?

I don't think the tossup in this form is as doomed to be transparent, but depending on what you think of the idea, the tossup might always be somewhat transparent. Not sure if it will still be too much of a problem?Draft of Tossup Rewrite wrote:In a musical set in this city, the main character’s store sells a lottery ticket that has a 96,000 dollar payout and Nina, Vanessa, Daniela, and Carla gossip and tell each other to "tell me something I don't know".

I really like this rewrite and think it will play a lot better. The answer space is still pretty small, but Catherine makes a excellent point about other possible cities.

csheep wrote:The opera toss-up on "three" seemed ill-conceived. It was easily fraudable/very transparent, and doesn't seem to be particularly important as a concept to ask about with the clues selected.
Part of the reception we got was that the clue on Don Giovanni (that "this many characters are on stage" when he's dragged to hell) was pretty bad, since in many productions various demons are on stage during that scene, so I replaced it with a Nessun Dorma clue. When I wrote the tossup initially, almost every clue was from The Magic Flute, but that didn't allow for great pyramidality, so other clues were added in, making it less thematically consistent. I'm less convinced that the tossup is particularly fraudable, and not much of the direct reception we received at the mirror focused on that aspect of the tossup, but I can certainly see how that would be true, and if other people seem to agree that it's transparent we can certainly replace the tossup with some other opera answerline.Slight Edit of Tossup From Packet 4 wrote:In one opera, this many child-spirits prevent a character from committing suicide and tell another character to play magic bells to summon his lover. Lauretta’s father exclaims “Niente!” [“n’YEN-tay”] this many times before the aria “O mio babbino caro.” This many characters respond to a character’s aria “Zu Hilfe! Zu Hilfe!” [“tsoo HILL-fuh”] where he cries to the gods for help. Calaf says “vincerò” this many times at the end of “Nessun Dorma”. This number of characters place a (*) padlock over another character’s mouth to punish him for lying. Puccini’s Gianni Schicchi [“jah-nee SKEE-kee”] is the first in a series of this many operas. An opera in which Truffaldino tries to make the Prince of the King of Clubs laugh is titled for this many oranges and is by Prokofiev.

Packet 5 wrote:Eshelby names a form of this quantity that he described to be caused by “configurational forces” by equating bulk tension with bulk free energy. A pair of measures for this quantity named for Piola and Kirchoff differ in the fact that the first measure is a multiaxial generalization of the second. (*) Lamé’s ellipsoid is a method of visualization for this quantity using a principal axes model. The yield point represents the threshold for this quantity after which an object experiences inelastic deformation. The shear form of this quantity is the product of gamma and shear modulus. This quantity’s tensile form is found in the numerator of the definition of Young’s modulus.

I'm not a great player, but, yeah, the jump from the first two clues to third sound is quite the cliff for me. Looking over the Greiner et al. clue, it might be better to replace "system" with "Bose-Einstein condensate", but that also reduces the answer space. I think it's ok as is.Packet 4 wrote:20.

Surprised you didn't point out the larger amount of jazz questions than normal, too! Because opera was in the 1/1 music and opera subdistro, the Other Auditory Arts distro ended up being very jazz and ballet centric. I believe it ended up being something like 3/2 jazz, 2/3 ballet, 1/1 musical theater, and 2/1 misc. music (stuff like the gongs tossup). I personally liked how the other audio distro turned out, with removing opera leaving a lot more wiggle room for the other areas, but if that seemed like legitimately too much we might consider replacing some of the questions. Can't speak to the CS distro, other than it was intended to be 0.25/0.25, which seemed okay to me – the other science distro was definitely mostly padded with math and CS, with math being 0.45/0.45.kiwikoalabear wrote:Also, ballet (yay!) and computer science definitely came up a lot more than usual.

The mention of "chain rule" first before specifying that it's the "Euler chain rule" seems a bit ambiguous to me, since it could also refer to just the normal chain rule. Perhaps using a different name for the operation or mentioning Euler before chain rule could make it slightly less confusing?Packet 4 wrote:Lewy’s example is an equation involving this mathematical operation that has no solution.

This is a nitpick, but the "namesake 'shock proteins'" clue implies that the answer is "heat," while all the other clues point to temperature.Packet 5 wrote:Researchers in 2007 observed the effect of sudden changes in this variable in the upregulation of alpha crystallins, or sHSPs, in the eggs of zebrafish.

Besides the fact that the last 3 or 4 "this variable" tossups in bio have all been temperature, that is an excellent point. Not sure why I didn't buzz until hypothalamus.

I was curious about the first line because the Wettin dynasty comes from Germany and then ruled Poland, but the way it is worded means that isn't what they are asking about.Your Feline Genome wrote:ErikC wrote:Could I see the earth science tossup on water and the history tossup on Poland?This line through me off.

I wrote this tossup; I think the first line excludes Germany (it would be odd and untrue to say that any member of the House of Wettin was a "monarch" of "Germany"), but let me know if you thought the wording was confusing.ErikC wrote:I was curious about the first line because the Wettin dynasty comes from Germany and then ruled Poland, but the way it is worded means that isn't what they are asking about.Your Feline Genome wrote:ErikC wrote:Could I see the...history tossup on Poland?Packet 13 wrote:One of this modern nation’s monarchs from the House of Wettin battled a rebellion which ended after a “Silent” meeting adjudicated by foreign troops.

The main confusion would be monarch "from" this country; after Augustus the Strong was born in Germany and ruled there before becoming king of Poland. Perhaps saying "a ruler of the Wettin dynasty became king of this country" would be more clear.Charbroil wrote:I wrote this tossup; I think the first line excludes Germany (it would be odd and untrue to say that any member of the House of Wettin was a "monarch" of "Germany"), but let me know if you thought the wording was confusing.
The first line doesn't say "from this country;" it says "this modern nation's monarchs from the House of Wettin." Do you think that's still confusing?ErikC wrote:The main confusion would be monarch "from" this country; after Augustus the Strong was born in Germany and ruled there before becoming king of Poland.

Sorry, I didn't quite get that right. I would say it's ok but there's a chance someone might reflex buzz if they recognize the dynasty as a German house. There's also a chance someone interprets the Kingdom of Saxony as a "nation" I suppose - wasn't Bavaria referred to as a nation at some point in the tournament? But both of those things are pretty large jumps that I don't think people will make so fast, so the question seems fine.Charbroil wrote:The first line doesn't say "from this country;" it says "this modern nation's monarchs from the House of Wettin."

I don't think this is necessarily true.

Unfortunately, I think this might have been a consequence of the rounds you didn't play having those tossups (well, there was a tossup on "boundedness" in one of the finals packets, as well as an algebra tossup on "invertible" in one of the later packets). Also, I object to calling number theory "silly". :PProgcon wrote:I thought the math in this set did not seem very "curricular". I do not remember any analysis or pure algebra tossups.

I was a little hesitant just calling it the "Euler chain rule" because that's not a canonical name, but I'll look into changing the wording.dni wrote:The mention of "chain rule" first before specifying that it's the "Euler chain rule" seems a bit ambiguous to me, since it could also refer to just the normal chain rule.

Well, probabilities are numbers, not limits, and in this case the number is 1. As an analogous example, let's say we choose a random real number between 0 and 1 inclusive and are looking for the probability that we don't pick 0. This probability is 1, because even though it's possible to pick 0, there are infinitely more ways to get a non-0 number than 0 (see also this article).Aaron Manby (ironmaster) wrote:The bonus part asking for the probability that a random walk returns to the origin, is "approaching 1" acceptable? And if not, is there an ELI5 reason why it's exactly 1? I can't seem to find a good explanation that I understand.
