I kinda have the same problem, and why I'm going to bite the bullet next year and do a diploma in general sciences, and two courses in maths, then hope to study cosmology or physics...I'm still undecided.

I think it is possible to have a theory explained in such a way you can layer the model to the environment around you and it starts to fit. Remember 60 or 70 years ago only a handful of people properly understood relativity, now thousands understand many if not all aspects of relativity without having any mathematics to back it up. I'm not saying you'll make a huge impact by expressing your own theories through words, (you'll always need equations to back up models) but it is possible to get that 'revelation' through logic, and then go about using maths to prove your theory.

It's purely how you explain your ideas and make your level of knowledge clear. My problem is that I'm constantly going back on myself and checking how factors fit with what I know and keep on coming across gaps in my understanding...so I come across as a bit of a bumbling fool, however it's easier to learn from your mistakes and those gaps will start to close. I think people have a hard time in replying to posts on 'big' subjects because they're unsure how much to cover, so it's a case of asking the right questions, and taking it step-by-step.

This is purely from my perspective, a lot of the questions I ask aren't generally what I believe to be true, but I need to clarify that they're not before I can move on...which is roughly 0.09 m/s

With the quote above we can safely assume that thermal dynamics (with regards to the 2nd law) holds inside a black hole' date=' and it's eventual inflation. Space-time breaks down, but as the 'arrow of time' continues (despite getting skewed relative to it's source) then (this may be way off the mark) the universe generated is out of sync with our 'arrow of time'[/b']. I'm figuring the dimension of time is fundamental to these sister universes not 'bumping' ours. (again correct me if I'm going wrong here.)

Ok, the last bit of the paragraph (italic) is almost predisposing that there needs to be a factor so that a universe can exist relative to ours, and as these universes don't exist in a 'larger arena', this isn't necessary...and not really what I was getting at, but can see this statement being misinterpreted. The first part of the paragraph (bold) I'm going to stick with unless someone can find fault with it.

Maybe I'm just clutching at straws with the last post. However if anyone can explain how a collapse of space-time can happen before inflation, without the need for a large enough mass to be present (to obviously form a black hole) then this will explain the paradox I'm struggling with...any help please.

If my questions are too confusing or just plain daft, then I'm more than happy to take it on the chin.

hmm I get this too.. I dont always have the urge to cover up that area' date=' but it is certainly from fear of it hitting you there...

 

I do have a mild signs of OCD, so it goes along with that...[/quote']

 

But why this specific area...I take it you press between your eyes. If it was fear of getting hit, then surely you'd cover something more vulnerable like your eyes or cover your face. It seems strange that you're now the third person that applies pressure on this specific point ?

 

I guess we need a few people who have OCD that don't experience this odd habit, or vice versa...I'm still unclear how the two are connected. It's a sensation that occurs like an itch (when I'm tired it happens), rather than an obssesive compulsion.

40hz...aptly named subsonic. You'll find most graphic eq's on sound systems don't have 40hz as an option. You'll need to get some mastering software to enjoy it's delights.

Oh, as YT2095 stated the wave shape is important to get sufficient resonance. Sine waves have no harmonics so it's easier to achieve a precise frequency.

Oh' date=' hm, maybe there is a physical aspect to it then. Apparently it takes about a month (if I remember correctly) for habits to be ingrained/removed, though, so maybe you just need to not do it for longer?

 

Of course, if it's not an inconvenience (and it doesn't sound like it is at all) it's probably not worth the effort of removing the habit.[/quote']

 

I'll give it a go (this, whatever it is, has been present for several years), and it's hard to describe exactly the sensation I'm feeling to make me press between my eyes.

 

It becomes an inconvenience if I'm in public...actually I remember getting it a few times when I've been really tired on the way to work on the bus...no pointy objects in sight. Though pointy objects can really set it off, sometimes I have to press my palm really hard on the area until it stops ??? I'm more puzzled by this the more I think about it.

A new tract can continue outwards from the pit of a black hole WITHOUT BUMPING US.

 

this is the really hard thing to understand' date=' there is no denying that it IS difficult to picture----the new tract made by continuing onwards from the pit of a black hole DOES NOT BUMP OUR UNIVERSE[/b'] because it is a continuation with its own time direction. And we don't share any larger encompassing arena with it---there is no "absolute space container" containing both our universes in which they can bump.

I have a few more questions (apologies if this all seems obvious to most)...and paradoxes that are bugging me.

With the quote above we can safely assume that thermal dynamics (with regards to the 2nd law) holds inside a black hole, and it's eventual inflation. Space-time breaks down, but as the 'arrow of time' continues (despite getting skewed relative to it's source) then (this may be way off the mark) the universe generated is out of sync with our 'arrow of time'. I'm figuring the dimension of time is fundamental to these sister universes not 'bumping' ours. (again correct me if I'm going wrong here.)

With regards to the first law does there have to be a 'mother' universe, where matter is essentially being borrowed to form the other universes. The one thing I can't get my head round is if black holes are formed by a star that's big enough for there to be gravitational collapse then there would have to be a uniformed 'mother' universe for black holes to be generated in the first place. So how does an initial collapse happen to form the start of this 'mother' universe ?

The only way I can see round this...(so it's probably wrong) is if the amount of matter needed to create a black hole is relative to other objects in space-time. So supposing (in our universe) the calculations that constitute when a star collapses is relative to the uniformed objects that are already present, then in the beginnings of this 'mother' universe is it possible to have collapse on a much smaller scale. I've already started a thread with this idea, and was predominantly ignored (so I guess it's incorrect) but how can you have this initial collapse to start the universe when there's nothing big enough around to constitute a collapse ? Am I delving into something that really requires a hell of a lot of maths behind it, or can this be explained so I can start to build a mental picture.

Just for the record I've heavily considered that space-time is 'where', and I think I was slipping up by removing myself from the model of the universe in order to build a mental picture, so creating 'boundaries'. I think it's a case of getting over old habits when visualizing models, and why I keep on having to go back on myself when applying relativity to these models.

have you ever been hit in the eye with a pointy object? do you wear glasses?

I'm not sure what's happend to 6431hoho, but I'll be happy to answer this...no and no.

Perhaps visualize a chainsaw as opposed to a guitar ?? A little excessive I know, but desperate times....

Thankyou very much Martin, this is precisely the kind of answer I was looking for.

I reiterated 'boundaries' as I understand the basic principles of relativity but sometimes have to go back on myself when trying to visualize it's effects...exceptionally hard when you have other universes to contend with...this is now a lot clearer, and has opened many other questions...especially with regard to thermal dynamics.

Needless to say I will be picking your brains (or anyone else adept in the subject ) as this theories implications has been using a lot of my thinking time (if you don't mind.) In fact the last few questions in the OP have been plaguing me for quite some time.

I am, relative to the experts, very new to the subject and it's only recently that I've developed a passion for understanding physics, but you've made my day, thankyou

I also know Attention Deficit Disorder exists because my brother has it... He cant concentrate for more than a minute' date=' two at most.

[/quote']

 

There's a lot of aspects of ADD / ADHD covered in this thread...

 

http://www.scienceforums.net/forums/showthread.php?t=736&highlight=adhd+add

 

The fact your brother has been diagnosed proves nothing, the symptons for ADD are so broad and tenuous it can be attributed to any child behaviour.

 

Some of the symptons include fidgeting, looking out the window et.c which countless children do. Trying to combat these symptons with stimulant drugs is just insane IMO. I'm not saying your brothers condition is not a problem, but it could be a simple thing as something that's lacking in his diet, or something that can be solved with a psychologist, there are plenty of other methods to improve concentration.

 

A friend of mine was diagnosed with ADHD, and after his diagnosis and course of Ritalin he just became worse, as he had an excuse for bad behaviour all of a sudden, and he was constantly going up and down due to the effect and withdrawal of the drug. The condition should really be taken with a pinch of salt, and Ritalin is just bad news.

 

Sorry if this is slightly off topic to the OP.

ever had a piece of music stuck in your head' date=' and seems to play over and over again and you can`t shift it?

there`s a peice here: http://www.bosshousemusic.com/intro.html

and for the last 2+ weeks that`s been playing over and over, I`ve even been whistling it and not even known where it came from for the 1`st week.

I don`t know WHY it`s bugging me, it`s never happened like this before with a piece of music.

 

what are the reasons for this?

why does it happen to people, does it serve a purpose?

HOW DO YOU STOP IT!!!!

There are three reasons this happens I've found...sometimes it would be the last piece of music you heard say playing in a shopping centre, and that song tends to linger in your mind until you quash it with something else. It doesn't seem to matter what song is playing, if it's the last piece of music you hear for say, a few hours it will stay embedded in your mind.

Also, especially with a tune you don't particularly like, it's the 'must stop thinking about it' scenario which in turn makes you think about it, and it's just an endless cycle until you preoccupy your mind with something that overrides it...something important say.

The third is the all important 'hook' which is one of the skills in music that doesn't require any technical know-how, but just arranging a few chords that have familiarity, or are easy to play back in your head...you usually find it's just one bit of the tune that repeats itself, over and over and over again.

I can't give any technical psychological or neurological reasons why music has this effect, but I guess picture the artist being smacked round the head with a guitar and the music slowing and going out of tune, that seems to work for me.

In the latter case' date=' just resist doing it for a while and the habit will go away.[/quote']

 

I've tried this many times, but the sensation always comes back ?!

Wow, I get exactly the same thing...even to the point (no pun intended) that if I watch, say a sword fight on TV, I need to press between my forehead and nose (on the indent.) This urge isn't always present, but I've noticed it more when I'm tired.

I kind of attributed it to having the fear that the pointy object will hit me 'right between the eyes' but surely I'd cover my whole face or head if this was an irrational fear of getting hit in the face...so I rejected that idea. I'm finding it hard to relate this with a compulsive disorder...the indent almost tingles.

However I would say I'm a perfectionist when it comes to any creative pursuits. I also have a habit of arranging paper on my desk so it's perfectly in line with the edges of the desk...the same too when arranging my workspace in windows. However I can consciously ignore these urges, and in these cases I am being compulsive, but I see this as a gift when it comes to drawing or writing music.

What I don't understand is if there are multiple universes then black holes can only eventually inflate outside the boundaries of our universe

I'm using the term 'boundaries' very loosely indeed, it's purely to illustrate that there maybe multiple universes clustered as opposed to entwined with each other.

If these quetions are impossible to answer without getting exceptionally technical then please say, or if they're just impossible to answer, full stop. (period)

With regards to the recent findings by Ashtekar and Bojowald I have a couple of questions which maybe someone could answer.

If a black hole represents the beginings of a universe, and the inflation theory holds, in relation to our universe where do these 'other' universes reside ?

Given that we can observe black holes in our universe, does this mean they have not yet reached the stage of inflation (obviously we can't observe this) or are they actually 'gateways' (for want of a better word) into these other universes.

What I don't understand is if there are multiple universes then black holes can only eventually inflate outside the boundaries of our universe (which doesn't seem right to me) or they reside in another dimension that we don't experience.

Given that for every black hole there is another universe, and black holes in those universes and so on and so on, then the amount of dimensions needed for these universes to exist must be phenomenal. For each universe to exist in relation to the other, and the fact they all follow the same laws of inflation then each one would have to have extra dimensions so they can all exist alongside each other...hope this makes sense, I am struggling to get my thought process into words here.

Any help explaining where these universes exist in relation to ours would be greatly appreciated. I understand that there's nothing proven with LQG (as yet) but I remember thinking of literally infinite universes when I was very young so I have soft spot (if you like) for this theory...despite my very limited understanding of the subject.

This seems to become more of a lingual debate than neurological but anyway.

If I had a silver platter and I said under the lid is a freshly cooked chicken, and the scent of a freshly cooked chicken was permeating the air. If I then remove the lid to reveal a (da daaar) strawberry (which has been sprayed with a synthesized fragrance of cooked chicken.) Then the 'illusion' is created by the aroma.

You wouldn't be convinced I had a cooked chicken under the platter if I simply told you so, you would need the scent of the chicken to be convinced. In this case can we assume that illusions can be created through scent ? You wouldn't even need me to tell you there's a chicken under the platter...you'd just assume that was the case.

You do all realise this is from a Japanese sketch show 'The Laughing Dogs Passion' and is actually satirical. The band 'Happatai' which translates into Green Club are now a phenomenom in Japan, and rightly so, it's supposed to be, well...all of the above. I saw this first on a Chris Tarrant show (UK, trashy TV clips.)

I'm not really sure why this is under mit.edu ?? What are they teaching at M.I.T these days...these nappies have no scientific significance !!!!!

This reminds of the film 'single white female' where this is the very theme of the film. I've been googling and Jeeves'ing the subject for the last half an hour but there doesn't seem to be anything I can find without knowing the actual name of this condition. In the film I think it's the passing of the killers sister at childhood that stems an obsession with a new friend where she gets the same haircut clothes et.c then tries to dominate the victim and eventually tries to murder her and her boyfriend. I watched the flick many years ago, so not too accurate a description.

The only thing that vaguely relates I can think of is the freudean take on identification where you dress, act similar in a particular social group to 'fit in', and I guess this could go to extremes. Sorry if this is no help at all, perhaps if you search realted topics with the film you may find something.

'Copycat' seems to get sites on copycat killings, and early child behaviour but nothing about this condition ??

what is marmite actually supposed to taste of?? even the thoght of smelling it makes me cringe

Marmite was stumbled across, and it's taste is unique. So I guess marmite tastes of marmite. Twiglets taste of marmite...but you can't really say marmite tastes of twiglets as marmite came first.

Twiglest are intentionally supposed to taste of marmite.

I love it, and Twiglets, I also love them.

I can't believe I forgot about Twiglets, I have no trouble getting through a large bag of them.

I wish I'd get more of a post count for having things like the in the psychiatry forum..

You should read my jealousy thread...which also seemed quite popular

But seriously some of the most popular threads are due to someone getting it really wrong, so they tend to have more debate if that person still defends that position.

I wish I could remember my very first toy (with regards to the last post) I'll have to consult the parents. btw I had 'starscream', I really wanted the decepticon that changed into a stereo (or 'ghetto blaster' as they were referred to in the 80's) the name escapes me at the moment.

OR she was being fed and just didn`t like Brocolli

 

 

 

 

I have that same mem too (well not Exactly the same) I was woken up and taken out of bed' date=' sat on the floor in front of the TV (black and white) and watched that also, I specificly remember being told how important it was, but being more happy that I was allowed to stay up late to watch it [/quote']

 

Brocolli next to sprouts and mature cheddar is a taste that develops. They're strong flavours which is why so many kids love those hideous cheese strings, which taste like rubber to adults.

 

Yeah, your second point, having the same privelages as an adult means a lot when your a child. Probably why kids toys are so geared towards adult influences. Especially girls...they like to play with fake cooking appliances. Boy's, cars and hero figures...as a general rule.

my first memory was when i was around 2 ,my mom used to sing for me so that i could have a nap. I still remember those sunny days, crows which used to disturb my nap and mom's old song.

I still have analogue tapes of me singing to my mum, it's really cute how high my voice was, and my mum mimicking the sounds I produced.

My first memory was someone (I don't know who) was trying to give me something from a spoon. I was being held and I couldn't move. I remember hitting it somehow' date=' but it came at me again. I was crying but whatever it was got into my mouth.

 

I have never forgotten that.

 

Bettina[/quote']

 

Sounds like you were at the doctors if you were being held, and the fact that whatever was on that spoon had to be given to you. I might be wrong but I think the polio vaccine is taken orally, and I'm sure it's given to babies.

 

So your memory was probably in the first couple of years of your life...just guessing, sorry if that seems intrusive.

Anyway' date=' it's true that most people don't bother with WEP or WAP, because they don't know what it is, don't know hot to setup it up or just don't see the need to... whenever my cousin comes here (she has a wireless NIC (can I call that a WNIC?)) so she can pick up the neigbour's signal just by selecting 'connect' when her laptop automatically tells her she is within range of a wireless network.[/quote']

 

You can do the same as most of you probably know with PSP's. Also in the UK they've set up transmitters in train tunnels so you can log on using a lap top whilst on the move. If you're lucky enough to live in range you have perfectly legal free internet. Obviously there are no protocols otherwise they'd be pointless.

 

I think the majority of people in my local area are more clued up to security, the majority of signals I've seen on a friends lap top were WEP / WPA.
