I know that a black hole is just an object with an escape velocity > the speed of light, but does every black hole have to have a singularity at the centre?

Are we 4 dimensional beings only able to view existence in the 3rd dimension? If we were 2 dimensional, all we would be able to see would be line segments (1 dimension).
User avatar #3529 to #3474 - magnuskasparov ONLINE (12/11/2014) [-]
We actually see in 2d and our brain puts it together as 3d. Depth perception is an illusion, just like you can create a painting that looks like it has a lot of depth. The physical world, however, is 3d.
A 1-dimensional object is basically just a line, any line. You can describe any position on this line by only using one number. Think of it this way. Draw a line on a transparent sheet with a marker. Let's ignore the thickness of this line because that would be 2d and let's ignore the thickness of the paper. Now let's assume that every point you choose is the thickness of the line, so you don't have to deal with 2d. There are N possible points depending on the length of the line and the left end of the line is where the point called N is, now every increment is N+N until it reaches the last point. So in a line with only 3 possible places in order to describe the location of a point, the left endpoint would be 1, the second one would be 2 and the third one would be 3 so if you want to describe the middle you can describe it as point 2.
Now 2D is easier to explain, it's basically the same thing , but this time we take into account the thickness of the line and we can draw many other lines, but we still ignore the thickness of the paper and ink. 2D is basically how you graph stuff on early mathematics using X and Y axis. Now 3D has X(1D) Y(2D) and Z(3d) axis. Here we take into account the thickness of the ink and paper and now you can get the position of any point in the drawing you made in 3d. There are other dimensions, but I don't know much about them so I can't explain further, but I can guarantee that 4d includes all the previous dimensions. In the physical world, aka our world, we can't have 2D objects unless we ignore the thickness of atoms and ink etc.

Dimensions are stupid and heres why..

Everything is in 3d in one form or another. 2d like a paper, still 3d just lacks a big enough depth. In real life 1d and 2d are all a part 3d. Overall, its just a definition word we made to classify stuff, like give me that artwork on a 2d canvas.

There is no 4d regardless of what ppl told you. Thats retarded and your predictions of it based on 1d,2d,3d is inaccurate and false. And dont confuse time with distance, they will always be different to each other.

There is no more in our universe than height, width, and depth. However, Einsteins theory of realitivity shows how we often percieve time to be bending. Although thats just an illusion, time cannot really bend. At least not to my understanding.

Does anyone want to learn about fusion? Have any questions about fusion well come to this discussion board daw1217.freeforums.net/board/1/general-board and I or someone else will try to answer it.
This is for a school project soooooooo, yeah

how does one create cold fusion?
#3605 to #3473 - jimmyfofibby (12/17/2014) [-]
Oh crap I'm sorry for answering so late, but I'll answer your question now. Cold fusion is a very theoretical and hypothetical type of nuclear fusion although there have been ideas and experiments. The most basic setup of a cold fusion cell consists of two electrodes submerged in a solution containing palladium and heavy water. The electrodes are then connected to a power source to transmit electricity from one electrode to the other through the solution, this process takes weeks to even show change. Scientists also haven't agreed on a single explanation or experimental method that results can be repeated. Currently there is no accepted model of how to complete cold fusion. Hope I answered your question enough.

Do any of you guys/gals study trauma and traumatic events/stress? Kinda looking into it and it seems largely empty in terms of scientific journals and such. Anyone know where I can read some of them if they are even available to the open community?
User avatar #3490 to #3465 - iridium (12/10/2014) [-]
What are you looking for? Effects of stress on the brain? Effects on development? Effects on a person's personality? PTSD?
User avatar #3493 to #3490 - delio (12/10/2014) [-]
I was looking more towards traumatic events in children and young adults through either sexual abuse or child wartime effects. Things like personality shifts and tendencies that are developed after trauma and overly stressful events are also things I am interested in.
User avatar #3494 to #3493 - iridium (12/10/2014) [-]
Well, it's fairly common that children with these kinds of things end up either developing a mental disorder or it ends up being a catalyst or enhancer to one they may already have. I'd start there.
User avatar #3495 to #3494 - delio (12/10/2014) [-]
Do you happen to know if this area is linked more with Psychology or if it is linked more with something like sociology/human ecology?
User avatar #3496 to #3495 - iridium (12/10/2014) [-]
Mental disorders = Psychology of some kind (usually), so if you're looking at the effects of trauma in terms of the kind of mental disorders and damage to a persons behavior, then definitely look into psychology. Usually trauma relating to events, stress or brain injury have a relationship to psychology, or the mentality/behavior of an individual, which is psychology. So I would study psych journals. If you want a good shortcut to finding scholarly journal articles in google, just add at the end filetype:pdf, anything that you can actually read that is available to the public will usually be in PDF format.

Sociology concerns itself more with the behavior of social behavior but especially with societies and groups of people as a whole. There's overlap though so you can find stuff pertaining to sociology.

Thanks mate. Are you studying this stuff or just happen to know about this?
User avatar #3500 to #3498 - iridium (12/10/2014) [-]
My last three quarters of college have involved a Behavioral Neuroscience/Biopsychology course, a Social Psychology course and an Abnormal Psychology course all involving the use and study of peer reviewed journal articles, so I do study it I did officially become a psych major about a year and a half ago , but there's a loooot of shit I just happen to know as well, or at least know where to learn. Kind of why I hang around so many of the boards here.

Minimum number of 0D things (point with no dimensions) to make a 1D object (line segment) is 2
Minimum number of 1D things (line segment) to make a 2D object (triangle) is 3
Minimum number of 2D things (triangles) to make a 3D object (3 sided pyramid) is 4
So would the minimum number of 3D things (3 sided pyramid) needed to make a 4D object be 5?
#3647 to #3461 - smudgiemuffins (12/19/2014) [-]
You would be correct, I believe. It might be easier to think of it in terms of vertices. A line requires two vertices. By adding one more vertex perpendicular to the line those vertices lie upon, I can make a triangle. By adding a 4th point perpendicular to the plane that the triangle lies within, I have a pyramid. The logic should follow for all higher dimensions. All you have to do is keeping adding points that are perpendicular to the space that the previous object is within.

I figured this might be an appropriate board to state this. I've noticed that in both games, and in real life, girls tend to not lean as far forward when they run as guys do. Would if have to do with their breasts, butts, and some kind of balance type thing?
#3528 to #3458 - anonexplains (12/11/2014) [-]
could also be that girls tend to do things the "girly way"
what i mean by that is that males usually tend to use the most force when doing regular tasks,
exerting your body forward provides the most force possible

User avatar #3459 to #3458 - kebabs (12/06/2014) [-]
The centre of mass while running shifts forwards due the mass of breasts, this makes it more probable for the person to fall face forward if he/she is not careful.

i was watching a documentary some time ago, it was a two part doc where first a guy was exploring the dangers of diving sickness and seeing how long time deep divers avoided it. then the 2. part was about air sickness and loosing oxygen in high altitude,
anyone know whats its called? i'm only interested in the first part.
User avatar #3443 to #3434 - coronus (12/05/2014) [-]
The most common diving sickness is the bends, which is caused by nitrogen bubbles forming in the blood due to rapid pressure changes.

probably.

No prob. It is actually semi-historic; it's the first time since the 70's that a craft will have such a large perigee (5,790 km) and still return to Earth.

Hey I'm studying physics and it's quite probable that I'll do something related to medicine for my bachelors my university develops new medical equipment and that's what most of my physics lecturers are doing since these things need a shit ton of physics
