Q: Difference between sample size and replicates

PiomicronI am unsure of what is counted as separate samples, the size of a sample, and what is counted as a replicate, or if there is a distinction. The following is not a homework or assigned question, merely a question designed to make clear what the difference is: There are four blocks, A, B, C, and D...

I've edited my question, how do I ask for it to be reopened?

@RobbieGoodwin If there was a gun on a pole that moved exactly when you did, then despite seeing 5 seconds in the future there would be no way to dodge it. On the other hand, a man with a reaction time of >5 seconds could shoot at you and you'd be able to dodge it easily. A professional gunman of any kind with any gun will be somewhere inbetween.
Nov 9, 2020 02:58
@RobbieGoodwin I don't think I've changed anything at any point? I've elaborated some, asked for a general case, and here given a specific case.
Nov 9, 2020 02:58
@RobbieGoodwin Because I want to know a more general answer, not just in this specific circumstance. This scenario is specific so you cannot sneak or hide behind cover, or shoot first, or get behind the shooter because you're too far away. I want to know, in general, if a precog could dodge a bullet.
Nov 9, 2020 02:58
@Robbie Goodwin They can only see up to 5 seconds into the future. If they were out in an open field, and someone drove towards them to get in range of a shooter's gun, I'm not convinced there are a series of movements they could possibly do to avoid getting hit.
Nov 9, 2020 02:58
@RobbieGoodwin Five seconds before that, the precog was walking alone on flat plains and became aware of a soon-to-be visible vehicle carrying the sniper.
Nov 9, 2020 02:58
@RobbieGoodwin I have described and clarified a few times how the precognition works. It's not fixed or set in stone, involves seeing many probable futures, and although the precog can find favourable actions they can't lock the shooter's actions necessarily. They might be able to find the path where the shooter misses, but only if it's possible. The shooter reacts to every action taken, so where they shoot depends on what the precog does and where they are immediately before they shoot. Maybe I could handwave something once, but I want to know, based on the mechanics, in general.
Nov 9, 2020 02:58
@RobbieGoodwin To put it another way, say you were playing chess with a Grandmaster. You're a precog who can see 20 moves into the future, and for every move you do you can see what they'd do. Assuming there are about 3 moves each time you could do that aren't obviously stupid, that's 59049 ways the board could be arranged in the future, and you can choose any of them. Is it a surefire way to win? No, since the gm played close to optimally in all of them. Maybe if you're a Master yourself. That's with symmetrical starting positions. But you have no gun. So remove your queen and rooks. Win?
Nov 9, 2020 02:58
@RobbieGoodwin 5 seconds is simply a hard limit. Put it this way: the precog knows in 5 seconds the gunman will attempt to shoot at him, almost no matter what. But if there's no cover, and the gunman's far away then what can the precog do with most of that time? Where the gunman actually shoots depends only on where the precog actually is in 4.99... or so seconds. So what options does the precog have?
Nov 9, 2020 02:58
@RobbieGoodwin I'm not convinced there would have to be any potential future where the precog could survive. If the gunman was able to keep the gun pointed in your direction for less than a second then they could shoot a bullet at the centre of your chest and it would hit you. What movements could you do from so far away that would impair their ability to do that? You can see what they'd do based on what you could do, but what good is knowing that they will continue to tilt the gun in your direction?
Nov 9, 2020 02:58
@RobbieGoodwin As I have defined it, the future is not fixed. If there a series of movements you could do to not get hit by a bullet, a precog could find it, but a bullet is incredibly fast. If someone pointed a gun at the centre of your chest and fired, by then it would be too late to stop them killing you. So really, instead of dodging a bullet you're trying to stop them pointing the gun at you long enough to fire. But the further away they are from you, the less movement they have to do to correct their aim every time you move.
Nov 9, 2020 02:58
@RobbieGoodwin Can you prove it? Or at least, demonstrate that it would be plausible? If so, you're welcome to make an answer. Unfortunately, I don't agree that it's common sense that that would be true, necessarily.
Nov 9, 2020 02:58
@RobbieGoodwin What I want to know, though, is if a precognitive could, for example, begin movement before the gun is fired such that they could not be in the path of the bullet, successfully avoid ever being put in the crosshair, or be expected to trick the shooter into firing too far by feinting.
Nov 9, 2020 02:58
@RobbieGoodwin What I mean to say is, that the shooter's actions are by no means fixed, so if they see you moving they could potentially adjust their aim. The first quote refers to the fact that if a bullet is headed towards the centre of your chest or head, unless you are very far away it's physically impossible to move fast enough for it to miss by the time the bullet leaves the barrel. Any manoeuvres must be milliseconds from completion by the time it's shot, unless it's long-range.
Nov 9, 2020 02:58
@RobbieGoodwin Because the future isn't fixed, and if you move then the shooter can adjust their aim.
Nov 9, 2020 02:58
@JBentley technically not if you don't have enough time to write the thing, also in this case there are too many possibilities, and it takes into account everything that you could do, not everything you are likely to do, so you cannot predict your own choices like writing down the future, since you could potentially write down anything.
Nov 9, 2020 02:58
@John Anything within a 5-second interval.
Nov 9, 2020 02:58
@Dragongeek yes, but the more choices involved, the less they're aware of that future.

@BryanKrause Blood is 55% plasma, which is 90% water, and 40% red blood cells. Typical cells are about 70% water. If blood has a more or less typical water percentage then blood should be just under 80% water.
Oct 8, 2020 16:55
My lecturer said about 40%, but that seemed off to me.

@KorvinStarmast Innocent of that particular crime at least. The Bible names many as 'righteous' even in the Old Testament, and the presence of an idolater in a city doesn't mean nobody in that city knows and loves God.
Nov 28, 2018 18:35
@KorvinStarmast The question isn't why God would remove other false gods from the land, the question is why God would order them to kill everyone in a city (most of them innocent people) in order to punish the one who brought false gods into that city

@CortAmmon I feel there are a few issues in your answer. There are two roles in this game, and Death is allowed to choose whichever he likes. The rules I mentioned are unbreakable, so you'd have to use a method that is pseudo-random, and Death might predict that. Also, why not limit the scope of the game to a finite amount of numbered cards? You then find a way of picking one, and follow the method.

Q: What's the difference between a degree in Mathematics and in Mathematical Sciences?

PiomicronI'm considering degrees (in England) and I noticed that Mathematics and Mathematical Sciences are separate. What is the difference? Is it the case that one subject is a sub-subject of another? Would either have no advantages to studying over the other?
