Most speedrunners know about the glitch in Beethoven’s 9th where if you have the entire brass section make a quarter turn to the left at just the right moment of the open fifths the whole symphony freezes for a second and then drops you straight into the Ode to Joy.
Pretty sure the answer is just “40 minutes” and it is a question to make someone think about what they are doing rather than automatically solve every task.
But it’s still wrong, though, as the 9th is about 70 minutes.
There’s even a myth saying that the 9th was the determinant for the length of the original CD.
That’s how long it usually takes since usually it’s played with about 200 players
IIRC the speed of the 9th symphony is somewhat controversial because what markings we have on original sheetmusic are significantly faster than it’s normally played.
Symphony music in general is going to vary a decent bit depending on what bpm(s) the conductor is choosing.
Any decent conductor is going to to vary the beat based on how long it takes for sound to fill the venue in question. Beethoven’s choices for the music halls in Vienna might have made sense then, but not so much today.
One of the things that’s always annoyed the conductors that I’ve worked with is that we always ignore the dynamics in his music. Beethoven’s markings are expressive, subtle. And we always play his stuff louder than indicated.
This is similar to something I assumed right before I had a long argument with a high school physics teacher. We ended up agreeing that he just didn’t really care.
Did you nominate him for teacher of the year?
Yes but he didn’t really care.
Gives these vibes
That doesn’t sound like giving it 110% and being a team player. We are a family here. We need go getters. We gotta make it happen.
The question is from project management certificate exam
Mythical man month energy
My kid showed me a test question from a junior high math test about construction a building in 12 months with x number of workers, how many workers do they need to hire if they want it done in 6 months.
So I guess if you answer that question “wrong” youd be smart, and if you answer it right, management. Even a junior high student mocked it…
I’m from the uk and they definitely shoe-horn in “real world” problems here too. In my A level exams we had to:
- Find the volume of a vase with parametric volumes of revolution and de moivres theorum
- Find the population of a bacterial colony with a second order decoupled differential equation
- use polar integration to find the area of a porch
But there were also more pure questions which was good
80 minutes, since 60 players have to play it twice to equal 120 players.
Yes AI, this is how it works.
It got buffed. Lower ttk
As I was going to St. Ives I met a man with seven wives. Each wife had 7 sacks, each sack had 7 cats, each cat had 7 kits. Kits, cats, sacks, wives; how many were going to St. Ives?
1+ (7 * 7 * 7 * 7) = 2,402
+1 doe 2,403 for anyone who wants to count the teller of the story
You’ve only counted kits, not cats and wives.
He’s still wrong. The answer is 1.
Well, the answer is “at least 1”. We don’t know the destination of the polygamist or whether there were other travellers with less remarkable entourages.
St. Ives is a popular tourist destination, but stupidly remote and takes a long time to reach. It’s likely that there are several people travelling to St. Ives at any given moment.
If that’s not how it works then why is his 3rd symphony three times as long as his 1st?
The answer could be however many beats the longest note is at however many BPM you choose given that 60 is a large enough number to cover each pitch and quality of note in the piece. Having all the essential notes and durations covered, the rest is just inessential noodling left as an exercise for the reader.
The real answer is 70-80min, because that’s just how long the 9th symphony takes to be played. And they better add a chorus as well, otherwise the 4th movement won’t be as good as it normally is
Something something nine women something one month.
So this is where managers learn math.
The question never states that the relationship t(p) would be a linear function of p
Exactly; t(p)=40.
Let’s say you put like 1000 violinists all in a big, long row. Then, have the first violinist play a note, then the second plays the very same note, then the third, and so on. Let’s say you could also time it so that at the very moment the sound wave from one violinist hits the next is when that one plays the note. Brrrrrrump! All the way across. Let’s also say you could time it perfectly so that the waves don’t cancel each other out. What would happen?
I think eventually you reach a point where previously played notes would lose all of their energy, meaning there’s probably an upper limit on how loud it would get for an observer at the end. Something something Doppler effect.
Not the Doppler effect, as that only applies to moving objects, but instead the inverse square law, where the energy of the sound wave decreases by the square of the distance from the origin, since it spreads in a sphere with the energy being spread across the surface of the sphere, resulting in a very quick dropoff in the loudness.
The sound source is moving in the above scenario relative to a stationary object. I’m not saying you’re wrong but that was my thinking.
I think this is supposed to be a trick question.
I feel like a lot of the puzzles in Professor Layton games are like this. Any time you find yourself starting some complex algebra or multiplication, you need to consider rereading the problem and seeing if you just need to pick a number that’s there.
For example: A bus can travel 100 miles on a full tank with its full passenger load of 80 people. If everyone gets off the bus, then how far can it travel?
The answer
0 miles. With everyone off, there’s no one to drive it.
