Re: Tuesday, March 17, 2015 Game Recap & Discussion [SPOILERS]
That is the first I ever heard that 1 is not prime. There are other problems with the wording of the FJ clue, but I think I at least figured out what they meant, even if I came up wrong.
Congrats Kristin!

34 right.
Vene (3), Travel (5), Com (4), Ele (3), Rock (3), Party (4)
Salem (0), Star (2), North (2) Great Bear or Great Slave tossup right one, Enter (4), Comedy (1), "Quad" (3)
Lach Trash: "Julie Bowen"
I went past the 10's into the 20's and 23 pretty quickly.

Not to mention the Blight/Fungus clue, which was a $4000 swing in Colin's favor.jjwaymee wrote: I can never keep straight whether Great Slave or Great Bear was the biggest lake in Canada. That was a neardisasterous miss and rebound against Kristin.

Was "mold" acceptable for the fungus clue?

Now that I saw the FJ: I loved the clue! Of course, there was no way that I wasn't going to blank on it; I guessed 33.
Re: Tuesday, March 17, 2015 Game Recap & Discussion [SPOILERS]
Instaget, but they've overturned responses before after finding an old reference book that agrees with a player. Mathematicians disagreed on the primeness of 1 until relatively recently, and you can find math reference books from the 70s that call 1 prime.
While 1 is generally accepted to be nonprime, it's not as if there was a congress of mathematicians who set the rule. I'm sure you can still find a couple greyhaired mathematicians who are contrarians on this issue.
The writers may have been asking for a little bit of trouble with this one.

Thanks for the example: much clearer. I guess most FJ clues try to balance obfuscation and TOM. Whatever works.elijahjt wrote:The clue today was essentially [slight rewording here] This is the smallest twodigit prime number whose digits are themselves prime numbers.doihavetoreally wrote:What?elijahjt wrote:
I wonder, does Jeopardy! have clues along the lines of "This is the X that also fits Y limitation", when the solution satisfies "This is the X" alone? I didn't think they went for such trick questions, but do they?
If 11 were the answer (i.e. if 1 were a prime number), the clue could have just been "This is the smallest twodigit prime number". I'm curious if Jeopardy! has a habit of asking questions where the clue has an unnecessary limitation (in this hypothetical, "whose digits are themselves prime numbers").
Good enough to lose on Jeopardy!

While the prime factorization argument is compelling and doesn't require specialized knowledge, the best reason not to consider 1 to be prime is that it has a multiplicative inverse in the set. In the integers, it's useful to categorize elements as (1) zero, which always is special; (2) invertible elements, 1 and 1 in the integers; (3) prime, such as 3 or 5, which means that it's not in category (1) or (2) and the only factorizations are into 1 times the number or 1 times the negative of the number; and (4) composite numbers, for which there are other factorizations, such as 6 = 2 times 3. There are more general algebraic structures in which the elements can be categorized analogously. The elements in category (3) are building blocks, while the elements in category (2) lack any building blocks.

Nicely done! It seemed like Alex gave him a long time to get it so I came up with it. It's always nice to see a comefrombehind win! Congrats to Kristin. One thing among many I learned in my two trips to Australia last year is that Melbourne is their sportcapitol & it's also their second largest city.

I assume some Wardrobe person chose Alex's tie and did so with the date in mind. Kristin has worn green for four of her five games.dhkendall wrote:I wonder if Alex's tie (and Kristin's top) colour was deliberate today ...

She was wearing brown the day she missed with "Who is Mean Joe Browne?" If only that clue had come on any other day.

Turns out the correct wrong response was Graz.
Re: Tuesday, March 17, 2015 Game Recap & Discussion [SPOILERS]
What I get from that is that a prime number is a number which has exactly one prime factor. 1 is not prime because it has zero prime factors. If it were prime, it would have exactly one prime factor.

Ran Elements, and 4/5 in Compound. I have NHO "buttonhole" in either of those contexts.
I can play piano, organ, mandolin, guitar, bass, and most forms of percussion.
What led to American Express on Brands for $600?
I said Con Ed on the DD since I didn't know what the Con stood for. I assume it would fly.
Brad Paisley and Lady Antebellum? Thanks for the easy $2,600.
Party was totally over my head. I somehow knew that $600 was Ventura but had no idea what party. Also, is there any reason I should know who Eric Cantor is? He seems really low on the political totem pole unless you're from Richmond, VA.
There's an Irish Sea?!? I was completely hopeless on that category. I guess you could say I was… at sea. YEEEEEAAAAAHHHH!!!
I predicted that "college quad is short for this" would come up in "Quad"ruple, and I knew I was hosed since I had no idea what that was short for. I could've taken 400 guesses and never gotten quadrangle.
"Numbers, huh? Well, I've been making a ton of references to The Number 23*, so why not? Wait, smallest two digit prime... I know 1 isn't prime, so it's gotta be in the 20s. 21 and 22 are out… are you freaking kidding me?" Weirdest precall/instaget ever.
Holy CRAP was that a nail biter. Colin really put the pressure on, and I was worried Kristin was sunk with that lowball wager, but a misfire from Colin worked in her favor.
*Seriously, The Number 23 was not THAT bad. I liked it and know at least three other people who do. And yet it gets an 8% on Rotten Tomatoes?!

It doesn't matter if 1 is a prime number or not; 11 can't be a right answer. The clue specified that "both themselves prime numbers" meaning it couldn't be the same digit. 13 would have been a much more problematic answer (which I almost fell for).
Congratulations once again, Kristin. Dodged a real bullet there, but I knew you could do it.

Great job, Kristin! Mrs Penguin and I cheered when we saw your wager. But I still figured we'd be saying goodbye to you. Couldn't believe Colin missed it. Poor guy. I kind of wish you'd missed it too, just so people could see how savvy your bet was. Only they would've called it luck or Voodoo as they shook their heads in disbelief.
Here's to tomorrow when you win $39,800! Right?
