/sci/ - Science & Math

[Anonymous No.2760327]

These logical questions are the most frequently asked.
So /sci/entists, lend me your academic mind for a sec.

1.Why do Kamikaze pilots wear helmets?
2.What is the speed of darkness?
3.What level of importance must a person have, before they are considered assassinated instead of just murdered
4.Why do they use sterilised needles for death by lethal injection?
5.If it’s true that we are here to help others, what are the others doing here?
6.Why doesn't Tarzan have a beard?
7.Why do we press harder on a remote control when we know the batteries are flat?
8.If the "black box" survives every plane crash, why not make the entire plane out of that stuff?
9.If the universe is everything, and scientists say that the universe is expanding, what is it expanding into?
10.Isn't it a little scary that a doctor's work is called practice..why do they call it that way?
11.Should crematoriums give discounts for burn victims?
12.What is a free gift? Aren't all gifts free?
13.Why are there flotation devices under plane seats instead of parachutes?
14.Why do they call them "apartments" when they are all stuck together?
15.Why do people without a watch look at their wrist when you ask them what time it is?
16.Why is a person who plays the piano called a pianist, but a person who drives a race car not called a racist?
17.Why is it called "after dark", when it is really after light?
18.Does anybody ever vanish with a trace?
19.If you try to fail, and succeed, which have you done?
20.How is it possible to have a civil war?
21.Why do they lock gas station bathrooms? Are they afraid someone will clean them?
22.What do you do when you see an endangered animal eating an endangered plant?
23.Is there another word for synonym?
24.What if there were no hypothetical questions?
25.If the temperature is zero outside today and it's going to be twice as cold tomorrow, how cold will it be

The last one it seems to be the hardest to answer.

25. -131.575 degrees Celsius

[Anonymous No.2760355]

>>2760351
how did you calculate it?

[Anonymous No.2760356]

/b/tard here visiting /sci/:

For the last one, it depends what the actual measurement is. If it's 0 degrees Fahrenheit, that's 17.8 degrees Celsius. 0 degrees Celcius is 32 degrees Fahrenheit. Just multiply the converted number and then convert back to the original form of measurement.

[Anonymous No.2760365]

>>2760355
Convert to kelvin, divide by 2, convert back to celsius

[Anonymous No.2760372]

>>2760356
samefag actually trying to make the maths:

0 degrees Fahrenheit = 17.8 degrees Celsius
2(0 degrees Fahrenheit) = 35.6 degrees Celcius
35.6 degrees Celsius = 96.08

So if you're measuring in Fahrenheit, then 'twice as cold' as 0 degrees will be -96.08 degrees Fahrenheit outside the next day.

-----

0 degrees Celsius = 32 degrees Fahrenheit
2(0 degrees Celsius) = 64 degrees Fahrenheit
64 degrees Fahrenheit = 17.8 degrees Celcius

So if it was 0 degrees Celsius and it was going to be twice as cold tomorrow, tomorrow it would be -17.8 degrees.

1. To protect them from AA fire while they're still making their approach.
8. The resilience of the black box is due not so much to the material it is made of as to its structure. Airplanes need to be aerodynamic and have airfoils.
3. Assassination/murder is determined by the motives behind the crime. If a person is killed for a personal or economic reason, it's murder. If they're killed for a political reason, it's assassination.
13. If a lot of parachutes are deployed close to each other, they'll end up eclipsing each other, causing those higher up to fail due to the low-pressure zones created above a deployed parachute. It takes extensive training to avoid this in a mass air drop.
15. Force of habit.

1. because the helmets hold mouth pieces and earphones for communication. and breathing tubes i think.
2. N/A
3. if the killer is payed or politically motivated
4. because there is no point deliberately dirtying a needle when it makes no difference. (the needles start out sterile)
5.it isnt true
6. fictional character, IDC
7. i dont. i change the batteries.
8. because the plane would not fly
9. the matter in the universe is expanding. it is expanding onto empty space...which is what most of the universe is anyway.
10. in that context it just means 'to do'
11. no, they offer the same service, and it is just as costly to them as normal
12. yes. its redundant (like calling someone a stupid idiot)
13. because parachuting only to land in water will kill all the passengers. better chance of survival to use flotation devices. also " If you jump out of a jetliner, you would die. The plane is going about 600 mph, it's minus 50 degrees, and you would have a great chance at hitting the tail fin when you jump"
14. heheh, dunno lol.
15. they usually dont...if they do, it may be because they didnt know they were not wearing a watch
16. haha! lol.

1.: So they don´t hurt themselves _before_ their mission is accomplished.
2.: Darkness is not an entity, therefore it does not have a speed.
3.: It´s not the level of importance, it´s the plan and the intent of the murder.
4.: So if someone accidently wounds himself, nothing too bad happens.
5.: Helping others.
6.: because he´s fictional and more appealing to women.
7.: because sometimes it´s not the batteries, but the worn out capacitor, which will work with slightly more pressure.
8.: can´t be done on large scales.
9.: Into itself (seriously).
10.: because a doctor is not a magician that will instantly be able to do anything. He is human and does the best he can, errors cannot be avoided by mere experience.
11.: No, as burnn victims most of the time have not completely been burned and the time it takes to cremate them is not much different to that of usual corpses.
12.: That´s actually interesting, though i only heard this from dubious web pages trying to get your attention by using the word free. Soemtimes, in order to receive a gift, you have to do something and a lot of people associate "non-free" with money, nothing else.
13.: Because planes often land in water if there´s an emergency.
14.: Because of the walls between the apartments. A lot of people on one place, but separated by walls.
15.: habit.

1) Maybe they didn't want to hurt themselves before they reached their final destination?
2) "Sensitivity to light is modulated by changes in intracellular calcium ions and cyclic guanosine monophosphate"

However long it takes your eyes to send a new signal to the brain.

Otherwise, darkness is the absence of light, so I guess it could travel as fast as light (assuming light has disappeared to create darkness)
3) I think this definition more accurately reflects the nature of an assassination:
"killing or murder for political reasons"

Anyone can get assassinated.

19: failed at the task you wanted to fail at, succeeded at the task of failing. Everything is relative.
20.: War done by civilians instead of military personnel.
21.: I only know gas station bathrooms that can be accessed from outside the store. They lock it so nobody can destroy them too easily, steal something etc.. Also, they mmostly take money for opening them, so they get paid for cleaning them after the mess you created there.

8. Matter's totally indestructible. Why not just make everything out of matter?
9. It's not expanding into anything. They say the distance between things is getting bigger - that's the "expansion". Space itself isn't expanding - there's just more space now than there was before.
10. There's a difference between practice and practise.

3. Iunno.
4. In case of a botched injection they don't want the convict to fall victim to a painful infection and then be able to cry "CRUEL AND UNUSUAL!!" in court.
5. .
6. He's a fictional character
7. Frustration? And attempt to coerce the battery? Or even, more logically, an attempt to complete a circuit in the hopes that the button is somehow damaged.
8. ..... It doesn't necessarily survive undamaged. Also it's extraordinarily heavy and wouldn't be a practical material to use in aircraft construction.
9. See: Theoretical Physics and String Theory.
I'd explain (Cause that's my field of study but it's for another time. Check out Brian Greene's books.)
10. Practice also means "to carry out"
11. Nope. Maybe they should give discounts for small people though.
12. You're right.
13. Good luck getting to the exit to parachute out. Not even pilots have parachutes in most circumstances. I'm a commercially rated pilot and I've almost never flown with one.
14. Latin most likely.
15. Habit? I dunno.
16. The English language is not a very logical one. Though you can say a "Racer..."
17. Most likely from "After night fall" but I don't know.
18. Nope. Not even if you vanished into a black hole. See: Hawking Radiation.

The point in time at which the person is considered "vanished" may be different then the point in time in which a "trace" is found.

1. For radio contact, and to protect them on their way to the target.
2. Darkness is an absence of light, not a thing in itself, and hence does not travel.
3. Not based on importance. Political motive = assassination.
4. As part of a charade to pretend the procedure is civilized.
5. It's not true.
6. Because he's more handsome shaven. (Bear in mind he's fictional.)
7. Frustration.
8. Because it would be too heavy to fly, and wouldn't survive anyway, since it needs the plane around it to protect it. Also, the humans inside wouldn't survive a crash, even if the plane was totally intact.
9. False assumption. It is not expanding into anything. The amount of space is simply increasing.
10. "Practice" means carrying out an action. The additional definition that includes "in order to get more proficient at it" is secondary.
11. No.
12. Yes.
13. Because your chances of survival are better with a crash landing than in a mass parachuting, and planes often fly over water.
14. Because the building is divided up.
15. Habit.
16. The racer races, but the pianist does not piano. They are not analogous.
17. It means after it has become dark.
18. Yes.
19. You have failed at the original task, and succeeded in the task of failing at the original task.
20. "Civil" in this case means pertaining to citizens.
21. For various reasons, for example to keep homeless people from sleeping in them.
22. Nothing.
23. Not exactly, but several words are close, depending on context.
24. Then civilization would not exist.
25. "Twice as cold" is meaningless, since you cannot have a quantity of cold.

2) Darkness has no upper bound on speed. Imagine you rotate something around a light bulb at just below c. The shadow it casts will cover greater distance yet will complete a revolution in the same time. Greater distance per unit time = greater speed. It all depends on how far the wall is from the lightbulb.

25) "twice as cold" requires the temperature of the day before 0 degree day to answer, otherwise it is nonsense. "It's 100 degrees today, tomorrow it will be 0 degrees and the next day it will be twice as cold. Twice as cold = -100 degrees'.

Ok, let's play dumb and answer seriously to jokes.

0°C or 0°F aren't meaningful centers for homotheties.

In a thermodynamic context, you should consider the absolute zero, -273°C, in which case the answer is -273/2 = -136°C (but this is absurd).

When talking about the human sensation of cold, you should consider the temperature of the human body, 37°C, in which case the answer is (0-37)*2+37 = -37°C.
