/sci/ - Science & Math

suggested question categories

I've got a set of astronomy questions floating around from 6 months ago...

Q1

I bet you'd like me to ask for Engineering for 10 points, wouldn't you OP?

>>1828934
I don't have any questions yet. I was just going to make them up on the fly.

>>1828938
What is Inflation?

>>1828938

what is de bang big

>>1828938
What is your mothers 'freshman fifteen', OP?

>>1828911
Big Bang?
Also can the math questions feature one of my assignments.

>>1828955
Oh i meant what is the big bang.

>>1828955
Maths is what's missing. Thanks, I couldn't think of another category.

>>1828955
Thats not a very coolface answer, c'mon

>>1828971
That was on real jeopardy.

>>1828976
moot was an answer on real jeopardy I believe

>>1828943
Obvious winrar.

Q2

OP here, can we at least decide on 5 categories for questions?

>>1828998
What is a QUASAR

>>1828998
i dont really know this one. il guess anyway,

What are Type II Supernovae?

>>1829008
Nope. Hint: Supernova come in type Ia, Ib, IIa, IIb ... etc

Engineering for 10 points

>>1828998
What is a Type Ia Supernova?

>>1829031
What is a Mohr Circle?

>>1828998
Time's up, Type Ia. These are white dwarves that siphon gas off a neighbouring binary red giant. Once the mass of the white dwarf (and hydrogen envelope from red giant) reaches the Chandresakar limit (1.44 Solar Masses), it explodes. Always with this mass, this is why they all have the 'same' energy (same, astronomically).

Q3/8

>>1829044
Correct.

jeopardy had a pretty good idea - they give you the answer and you give the question. But it got really lame whenever their "answers" seemed more like long winded questions and the questions the contestants were supposed to supply became no more than "what is ___"

>>1829049
the outer part because it spins as fast as the inner part even though it shouldnt (hence the need for dark matter)

>>1829049

Not sure if this is what you're asking, but "What is the outer part of the galactic disk?"

I just know that it's only the parts of the galaxy farther from the center that show the unexpected velocity-vs-mass-inside-their-radial-position relationship.

Random for 10 points

>>1829065
No, what you're referring to is one of the leading inclinations toward dark matter, however your answer is incorrect, or at least be more specific when referring to the geometry of the galaxy...

>>1829074
I agree, it's not a very good question, however, still no,

Dark must be distributed spherically symmetric with approximate constant density (this is the geometry that gives rise to flat rotation curves), putting most of it in the halo of the galaxy. The halo is the part of the galaxy above and below its disk.

Q4/8

>>1829077
What is the Fourier Transform?

>fast way of analysing [sic] signal data
>fast

No, wait--what is the FAST Fourier Transform?

>>1829103
What is the Hubble relation?

>>1829103
>the This Relation, named after its discoverer
>the This Relation
>named after its discoverer

Dr. This?

>>1829108
Ye son.

Q5/8

>>1829105
Correct.

>>1829119
What is the cosmic microwave background radiation?

>>1829105
>ausfag = analysing
>matlab fft = fast
Just saying.

>>1829127
yadda yadda yadda..

That Fremen

>>1829136
There's literally billions of possible answers for this one... shot in the dark just cause of it's proximity,

What is Andromeda?

Physics for 10 points.

>>1829136
What is ESO 325-G004?

>>1829169
What is a jerk?

>>1829169

What is acceleration

>>1829183
That's the second derivative.

>>1829181
I guess we can accept that. Though we would have preferred "what is jerk?"

>>1829195

Yeah, I realized that right after I posted it too.

>>1829169

Why is the third derivative of displacement useful?

>>1829210
Trauma to the human body is related to jerk experienced during impact. Acceleration sensors measure the acc of a test dummy, then this is derived to estimate the risk of trauma being sustained.

>>1829226

you misunderstand. You gave an answer so I supplied the appropriate question. Isn't that how this game is supposed to work?

>>1829169

>physics
>change in acceleration

Has that ever been useful? As the question states, "trauma", this is more medicine directed.

>>1829262
I didn't really think that was a physics question, and I knew somebody would question how valid it was. I'm mech eng, so I know nothing of physics, chem, biology etc. I just thought it would be fun to have some jeopardy on /sci/.

>>1829297

Keep it coming with the questions, you are forgiven aready

I'll take "Chemistry" for 10.

Physics for 10, since the first physics wasn't really physics.

>>1829376
what is the rankine cycle, alex?

>>1829389
Unfortunately that's not the answer we were looking for.

>>1829389
am i right or what?

>>1829376

hair dryer

>>1829428
lol fuck i meant

what is the carnot cycle?

>>1829431
We were looking for 'What is the Carnot cycle?"

Chemistry for 10

>>1829442
what is NMR?

>>1829467
Correct.

I have to get ready and go to work soon, so someone else will have to take over shortly.

Biology for 10

>>1829485
what is influenza?

>>1829485
Typhoid?

>>1829501
Correct.

Alright guys, I'm retiring from this. It worked out better than expected. Next time we do this we should use the question category screenshot to track what questions we've asked and tripfag to track scores etc

bump, im home. bit disappointed that nobody continued.
