@ACuriousMind Yep, thanks.

Well...no.

heather

Hello, everyone

0celo7

@ACuriousMind @Danu I want f(J)=[a,b]

In general you'll overshoot that target

ACuriousMind

@0celo7 I know, the interval I gave you should do that, no?

0celo7

Let me reread.

@ACuriousMind proof that such a thing is possible?

Do you know you can pick these points?

ACuriousMind

What do you mean? if you couldn't, that would mean that somehow either $f^{-1}(a)$ or $f^{-1}(b)$ is dense in $I$. But that would mean $f$ is actually constant on $I$ with value $a$ (or $b$).

Well, not dense in $I$, but dense in each interval $[c,d]$ with $c\in f^{-1}(a)$ and $d\in f^{-1}(b)$.

0celo7

12:23 AM

@ACuriousMind Yeah I'll think about it when I get home.

@Shing you subject the atom to radiation at the frequency of whatever transition you want, and for a time equal to half the time it would take for a full transition.

@DanielSank, thank you!

Sir Cumference

3:16 AM

@0celo7 Say, I've been thinking about what you said regarding lower mass limits for black holes

Does that mean that for certain objects, they cannot form an event horizon no matter how much you compress them?

0celo7

@SirCumference Maybe.

That's for an eternal Kerr black hole, nothing dynamic.

Sir Cumference

@0celo7 Oh, okay, so what about time variant black holes?

0celo7

3:49 AM

Not sure

Thats CW's domain.

Sir Cumference

:(

John Rennie

4:09 AM

@SirCumference an object with a large enough angular momentum can't collapse to a black hole unless it can get rid of the excess momentum.

Sir Cumference

@JohnRennie Yes, I know

I'm talking about mass though

That couldn't create a naked singularity, could it?

John Rennie

But in a real object there are ways to redistribute the angular momentum. So the core might be able to transfer angular momentum to the outer parts so the core could collapse.

You need to be a bit cautious about naked singularities. While we can construct a mthematical object that has a naked singularity that doesn't mean such an object could ever physically form.

For example there are various arguments that an extremal Kerr black hole couldn't ever form.

Sir Cumference

4:32 AM

@JohnRennie I'm talking about a lower mass limit though, not an upper angular momentum limit

John Rennie

There is no lower mass limit on any black hole.

Sir Cumference

@JohnRennie @0celo7 described the lower mass limit for a Kerr black hole as

Oct 19 at 20:52, by 0celo7

you need $e^2+a^2\le M^2$

John Rennie

That isn't a lower mass limit, that is an upper angular momentum limit.

user228700

Hi everyone :-) @JohnRennie: Morning!

John Rennie

@Kaumudi Morning. Doing physics on a Sunday? !!!

user228700

4:41 AM

:-P Everyday sir...

user228700

Speaking of physics (:-P), I'd asked a question about gun recoil yesterday...

user228700

19 hours ago, by Kaumudi

OK. When a bullet is fired from the barrel of a gun, if the bullet+gun system is considered, the net momentum must remain the same, before and after the trigger is pulled, since no external forces acts on the system. So, as the bullet moves in one direction, the gun recoils in the opposite direction, hence conserving the momentum of the system. The explosion of the gunpowder causes the bullet to propel forward. Which force causes the gun to recoil?

Secret

Neutron holography. Good for imaging internal structures in 3D

John Rennie

@Kaumudi OK, what do you want to know about this?

user228700

"Which force causes the gun to recoil?"

John Rennie

4:49 AM

> The explosion of the gunpowder causes the bullet to propel forward

Is that all the explosion does?

user228700

Ah, this explosion causes the gun to recoil too?

John Rennie

Correct! The explosion creates a high pressure gas. The gas exerts a force on everything that it touches, which includes both the bullet and the gun.

user228700

@JohnRennie Ohh, I see...

user228700

Didn't know how it actually works inside. Now Ik at least part of the physics involved. Thanks :-)

user228700

Weird...usually, there are only about 8 people around at this time...today there are 14 :-o

user228700

4:59 AM

@JohnRennie: Another quick question? (Sorry? :-P)

John Rennie

Yes, of course.

user228700

My textbook says "Usually colliding forces are impulsive in nature. Since the application time is very small, hence, very little motion of the particle takes place".

user116211

@Kaumudi They are modelled by Dirac Delta, a generalised distribution.

user228700

What do they mean by the words highlighted in bold..?

John Rennie

Any coliision takes a non-zero time because the colliding objects touch, then squish each other, then bounce back into shape and finally separate again.

user228700

5:02 AM

@MAFIA36790 Yeah, I toootally get what u mean (:-P) Googling...

user116211

@Kaumudi It just means the change in momentum is non-zero no matter how infinitesimal it might be.

John Rennie

But this collision time is usually short unless the objects are very squishy.

user228700

@JohnRennie Yes...

John Rennie

So we usually take the approximation that the collision time is zero

user228700

OK..?

John Rennie

5:03 AM

And that means the particles don't move during the collision.

user228700

Right, even tho their velocities change, yeah?

John Rennie

We assume the particles involved instantly change velocity when the collision occurs

Obviously this isn't physically realistic because it means the forces during the collision would be infinite

user228700

Yeah...

John Rennie

But we often aren't interested in exactly what happens during the collisin.

All we need to know is the change of momentum that happens

user116211

@JohnRennie And that's why they are modelled by Dirac Delta function.

John Rennie

5:05 AM

And this change of momentum has the technical name impulse

user228700

@JohnRennie Hm, OK...

John Rennie

Impulse (physics)

In classical mechanics, impulse (symbolized by J or Imp) is the integral of a force, F, over the time interval, t, for which it acts. Since force is a vector quantity, impulse is also a vector in the same direction. Impulse applied to an object produces an equivalent vector change in its linear momentum, also in the same direction. The SI unit of impulse is the newton second (N·s), and the dimensionally equivalent unit of momentum is the kilogram meter per second (kg·m/s). The corresponding English engineering units are the pound-second (lbf·s) and the slug-foot per second (slug·ft/s). A resultant...

user228700

Yes, OK! :-) Thanku!

user116211

@JohnRennie, you can link your post on impulse; there is a pretty good explanation in it.

John Rennie

That's why the textbook is using the description impulsive

user228700

5:06 AM

(That was fast and omg, was it to the point :-D)

John Rennie

@MAFIA36790 I must have answered questions on impulse many times over the years :-)

John Rennie

@MAFIA36790 this one?

A: The elusive difference between force and impulse

It's hard to think of a physical system involving a force that acted for zero time. However I think it's useful to consider a collision, perhaps between two billiard balls. When the balls collide they change momentum. We know that the change of momentum is just the impulse, and we know that the ...

Ok I initially did not see the result coming because I implicitly and unawarely assumed that an electron with property 1 passing through detector 1 and unchanged by it means property 1 is an eigenstate of dectector 1

user228700

@JohnRennie: Sir, in that post, u've written:

user228700

"With the soft balls we get a low force for a long time, with the hard balls we get a high force for a short time, but in both cases (assuming the collision is elastic) the impulse (and change of momentum) is the same."

user228700

What do u mean "Impulse and change of momentum "? Aren't they the same?

Secret

> If you are like me, you will probably find that this explanation is still unsatisfying. We are saying that the electrons seem to communicate faster than light, but somehow relativity is saved because as a technical matter we can't tell that it happened until later. Nonetheless, satisfying or not, Bell's theorem has been experimentally tested and showed that locality must fail, and at the same time relativity has been repeatedly tested and always worked, so until someone comes up with an explanation which shows more naturally why these two results should both be true, we seem to be stuck w…

@DanielSank Because of the excellent faculty especially mathematics.

@Kaumudi Probably, but no guarantees. It's late here.

There will be another day Kaumudi! Don't worry.

user116211

7:01 AM

There are lots of places to watch in Calcutta @DanielSank.

user116211

Mostly are from Victorian period.

user116211

There are some famous cemeteries; old parks; library; old colleges; Memorials!!

user116211

You can't finish in a single tour ;)

DanielSank

When I travel, I prefer to simply "be" in the foreign city.

I do like some museums etc., but mostly I'd rather wander the street, eat local food, and try to get a feel for the normal life.

I really dislike running from one tourist location to the next.

user228700

My textbook says that the normal force, tension and friction may be impulsive, but that it's case dependent. However, I read somewhere on SE that these forces, esp tension absolutely cannot be impulsive. Thoughts..?

user116211

7:04 AM

@DanielSank yeh me too.

DanielSank

For example, if there is a park that the locals go to in the weekend, then I'll go there.

user116211

It's good and really thrilling to explore the city yourself without any assistance.

user228700

@DanielSank Oh, man, if u're still around in half an hour...

DanielSank

@Kaumudi What do they mean "impulsive"? Like... acting for a very short time?

user228700

@DanielSank Yes, exactly.

DanielSank

7:05 AM

@MAFIA36790 I don't mind going around with a local... India would be a little overwhelming for two obvious foreigners, I guess.

@Kaumudi Hmmm, yes I would not say tension is usually impulsive.

user228700

@DanielSank Oh, definitely.

DanielSank

Nor friction :\

user116211

@DanielSank, When I first came in Calcutta, I explored the whole city myself for two days. Went from church to local restaurants; visited old shops; it was amazing ;))

user228700

@DanielSank Hm...can u please elaborate?

DanielSank

@MAFIA36790 There are churches? That's odd.

user116211

7:06 AM

@DanielSank O.o

user116211

Why do you think otherwise?

DanielSank

@Kaumudi It just seems rather unlikely. If I swing a ball around on a string at constant velocity, the force of tension is constant.

@MAFIA36790 Are there many Christians?

user228700

Hm, yeah, I guess...

user116211

@DanielSank Not many; but in a substantial number.

DanielSank

@MAFIA36790 Built by the English?

user116211

7:07 AM

@DanielSank yes.

John Rennie

@Kaumudi suppose you have a stone on a string and you throw the stone. There is no force on the stone until the string is taut, then there is a force due to the tension in the string for a short time until the stone bounces back. That could be an impulsive force due to tension.

user228700

And what about friction..? That too seems like it cannot exceed a certain value, yes...

DanielSank

@JohnRennie Yes.

@Kaumudi Friction also seems unlikely to be impulsive.

@MAFIA36790 Still in use?

user228700

@JohnRennie Yes, yes...

user116211

@DanielSank Yes.

user228700

7:08 AM

Alright, so it is case dependent.

user116211

I have seen one which is not in use too.

DanielSank

i.e., are there many Indian Christians?

user116211

John Rennie

7:08 AM

@Kaumudi you might be able to find an example where the force due to friction is impulsive, but I suspect this would be a bit contrived.

DanielSank

@Kaumudi I know ;)

John Rennie

@Kaumudi I've been to Pune ...

user228700

@JohnRennie Huh...

user228700

OK, then I'll wait and see if I come across any scenario in which these forces are impulsive.

user228700

7:09 AM

@JohnRennie Oh! When..?

John Rennie

@Kaumudi Suppose I'm driving my car slowly and I stamp on the brakes. The car will effectively stop instantly i.e. the stopping time is so short as to be negligable. That could be an impulsive force due to friction.

DanielSank

@JohnRennie That's a very interesting point.

What an interesting case to think about.

user116211

@DanielSank Well, I think the both.

DanielSank

There are two points of impulsive friction there. How odd.

Friction is confusing, eh?

John Rennie

@Kaumudi I can't remember exactly, but it was in the 90s. Unilever Hindustan was sponsoring research at the university in Pune and I went for a week for a conference.

user116211

user228700

@DanielSank: I'll be available to talk about touring India in like 5 mins :-P Pls be around.

DanielSank

@Secret This is a very good question. To put it simply: "How is entanglement different from classical correlated probability?"

@Kaumudi ok

John Rennie

@Kaumudi I think the point is that the frictional forces only act during the collision, so if the collision is short the frinctional forces only act for a short time.

DanielSank

The short answer, @Secret, is that each time we draw a sample from the classical correlated probability distribution, the two variables have values before we look.

With entanglement, they do not.

user228700

@JohnRennie They only act during the collision?

DanielSank

7:25 AM

At least, that's one way to say it.

John Rennie

@Kaumudi yes. Is that not obvious?

user228700

@JohnRennie Erm, actually, no...

user228700

Which force are u talking about?

user228700

(Yes, friction, but where is it acting?)

John Rennie

Consider the ball on the ground. It is stationary and no frictional forces are acting.

user228700

7:26 AM

Uh huh...

John Rennie

When the other ball hits it this produces a sideways force and on a frictionless surface it would make the ball on the ground move sideways.

Secret

@DanielSank so we cannot say the wavefunction of the entangled state contained all the outcomes in theory (i.e. they are predicted to be there, except they have not been realised), and measurements just happened to pick one of these according to the probabilities given by the wavefunction, and then realised it into an outcome observed?

DanielSank

@Secret Uh, sure, we can say that.

John Rennie

But if the friction is high enough the ball on the ground won't skid sideways, though it may rotate sideways.

DanielSank

But if we have two marbles, the marbles have colors before we look.

John Rennie

7:28 AM

So in this case we get a frictional force between the ground and the ball that only acts during the collision.

DanielSank

Let me put it this way @Secret, in classical physics, probabilities come from our lack of knowledge, but in quantum mechanics, they do not.

user228700

@JohnRennie Hm...

user116211

^ Isn't this obvious @secret?

John Rennie

user228700

7:29 AM

But not before @DanielSank: There is so much more to India! First question: are u a foodie?

DanielSank

@Kaumudi let me put it this way: I invented my own vegetarian dish after many iterations. I think it is very good. I served it to an Indian friend of mine. She was so impressed that she requested the recipe and served it to her husband, who liked it so much that he requested she prepare it again. The fact that an Indian requested a repeat of this dish is, to me, the final badge of victory.

Does that explain my attitude about Indian food?

user228700

@DanielSank Yeah, it's called Holi <3

user116211

@DanielSank The chili recipe? It looks awesome!

user228700

@DanielSank :-D Totally. OK. So food is a priority, yes?

DanielSank

@Kaumudi You have to ask?

user228700

7:32 AM

Just making sure :-P

user228700

When u say "Visit India", what does that really mean..?

Secret

Well because of the no communication theorem, I am always puzzled about why people said the subsystems instantly communicate, and after some studying I am wondering about treating the wavefunction as something that is not just a mathematical device, but something that is present in the system in question (which in some sense it makes sense because states (and hence probabilities) do evolve determinstically in quantum) can actually explain why saying they communicate is not necessary
(To be continuned)

DanielSank

@Kaumudi this is it. I don't know if the ingredients exist in India.

@Kaumudi It means get on an airplane in California, and eventually get off the airplane in India, then stay there for some time, and then do the process in reverse.

@Secret I'm finding this hard to follow.

user228700

In some places, eg: West Bengal, there are Brahmins*(who are technically supposed to be *pure vegetarians, ie. not even egg in a pastry or something) who are allowed to eat fish.

user116211

@DanielSank Surely; they are not KFC secret dishes ;P

user228700

@DanielSank: When did this conversation completely take a turn from tourism to food?!

DanielSank

@MAFIA36790 The recipes call for roti. I don't have roti...

user228700

7:46 AM

DanielSank

@Kaumudi When I pointed out that food is a priority when travelling?

@Kaumudi I have flour.

user116211

@DanielSank Just an Indian-English word. You can make them easily.

user228700

DanielSank

Ha! gulab jamun! I made those with a friend many years ago.

Such a straightforward idea: let us fry dough and dunk it in sugar!

user116211

Just a few days ago, I went to Amina; a famous old restaurant specialising in Dum Biryani; you shouls taste that @DanielSank.

user116211

@DanielSank One of my favourites.

user228700

user228700

user228700

7:51 AM

😛

DanielSank

@Kaumudi Kerala?

user116211

@Kaumudi No, I was not telling to you ;)

DanielSank

@Kaumudi Oh.

Wikipedia says "Kerala" for "God's own country" in India.

user228700

@DanielSank No, that as supposed to be a joke directed at @MAFIA36790. Karela is a type of leaf in Hindi :-P

user228700

But Kerala, yes, it's a state.

user116211

7:52 AM

You should visit North-east; they are a piece of art; exquisite tranquillity and serene panoramas and of course Himalayas @DanielSank!!

user228700

And omg I know the perfect place to go if u want to fall in love with Nature all over again.

DanielSank

You guys are sending me on a total tour of the subcontinent...

user116211

I should have mentioned Kashmir but there are recent tensions, so....

user228700

No, seriously, omg, that place.

user228700

@MAFIA36790 Kashmir? No effing way! Do u want to maybe die?

DanielSank

7:54 AM

Next you'll say I should learn Hindi and four other languages, take a degree in Indian cooking, and buy a house in Calcutta.

user228700

U know what? @DanielSank

DanielSank

You love your country, I can tell.

user116211

;)

user228700

:-D We do. @DanielSank! U should do something before coming.

Secret

MAFIA, Danielsank
Basically what I have in mind about entanglement is like this:

1. There are two marbles of no color, which we knew it will randomly become R G B or combinations thereof if you touch one of them. What color each marble become is entirely determined by this underlying probability and not some underlying thing such as the marble has some predefined color. The color each marble take when it is touched is independent on what happened to the other marble.
--> This is in analogy to the product state scenario of the two electrons

user228700

7:56 AM

And no, don't learn Hindi and all 😛 This is something that u can hopefully totally do...

user228700

@DanielSank

user228700

OK, I need to go have lunch, but @DanielSank: Have u heard of Ruskin Bond?

DanielSank

nope.

user228700

OK, just as I thought. Before coming here, read two/three of his books. They're only about 200 pgs each, so I bet u could finish them on the flight but yes, u must absolutely read his books if u want a feel for India.
