Physiology & Medicine / Wellbutrin or Cipralex?

« on: 25/07/2010 19:49:08 »

Hi all

I sometimes suffer from depression.

About 5 years ago I had a terrible bout of depression, my doctor put me on cipralex and I was ok after 3 months and doctor told me I could stop.

Recently in the last month or so, my depression has returned and now my doctor has put me on Wellbutrin XL 150mg. I feel like a zombie but that is ok because I have only been taking it for a week and it takes a while to work.

My question is : should I continue the Wellbutrin and hope it works, or should I go back to Cipralex because I know that did work for me....

Physiology & Medicine / Are oats healthy to eat for lunch/dinner?

« on: 06/07/2010 19:30:02 »

Hello Nutrition boffins!

Is it healthy to eat oats for lunch/dinner, can it help me to lose weight and will it be safe for my body?

I just want to add that I don't currently do this but I am thinking of it and I will throw in a few pieces of fruit during the day and some protein(tuna/chicken) as well.

I am currently going to gym 4 times a week, but I'm not happy with the results, that is why I want to try change my diet so I can lose weight.

Physiology & Medicine / I think my friend is anorexic, what can I do?

« on: 23/06/2010 12:37:29 »

I have a friend who is very thin, but she keeps telling me she is fat and she goes to gym every day and feels guilty when she doesnt go. She tells me she is FAT with a capital F and really she is no more than skin and bone. I dont want to tell her that she is anorexic because that might end our friendship so I need to help her in another way, please tell me what to do I am so worried about her cos she hardly eats and hardly sleeps and is always complaining that she is chubby and fat and it breaks my heart into a million pieces.

General Science / Teeth brushing technique?

« on: 19/06/2010 01:39:05 »

This is a question about rinsing the mouth after brushing your teeth...

In order to get the freshest breath, should you ....

a) rinse the mouth out several times to get all the toothpaste out ?
b) rinse the mouth out only once or twice so that some toothpaste residue is left inside the mouth ?

Thanks

Hey there

Is there any notation available for singing? Like the guitar tab documents or piano documents.

EG: If someone writes a song, and they want to tell the singer how to sing it then he/she will need to use a specific notation won't they??

What is this notation called and how do I google it??

EG : Which words to sing loud, which notes to hold, fade ins/out etc...

ur help will be appreciated

Geek Speak / Is it just me, or does gmail suck?

« on: 13/05/2010 11:56:35 »

I used google mail for the first time last week, and honestly I have no idea what the hype is. It lost some of my mails after i clicked on them and is so hard to use and so confusing that I just left it and went back to hotmail.

Now I am no computer newbie, I have been programming software for 10 years, so its not a 'user' issue in my eyes.

General Science / Do you agree with Hawking (about Aliens)?

« on: 26/04/2010 13:07:25 »

I tend to agree with Hawking, I think intelligent life out there would not be peaceful, just look at us!

He is right when he says we should just stay quite and hope nobody notices, cos if u think about it logically the more basic an organism is, then the more peaceful it is,and the more intelligent organisms get the more dangerous they become.


I hope if there is intelligent life out there, that they dont know we here.

General Science / Does science recognise psychic abilities?

« on: 08/04/2010 19:30:30 »

I think the question says it all, but in other words I am asking if any forms of psychic phenomena are acknowledged by science as plausible...

I do hear the odd story of psychic'c cracking cases in police work, and I still don't know how John edwards does his thing, so personally I would not rule it out, but I would be pretty doubtful since I dont think anyone could do something really psychic like predicting lotto numbers or the world cup winner...

General Science / How does this work? (maths)

« on: 02/04/2010 15:38:13 »

Supposed you have a right angled triangle with each of the smaller sides being 1 and the hypotonuse therefore being √2 (square root of 2).

the √2 is an irrational and forever repeating number, bound to go on for billions of centuries. There is not enough computers or paper on earth to actually store just this one number, yet a humble line of pythagorus is able to effortlessly depict it.

So how is it that a finite line can depict an irrational number? does that seem rational?

General Science / Why are scientists so sure that the light barrier is impenetrable?

« on: 25/03/2010 13:53:27 »

If history has taught me anything, it's this : Whenever human kind is faced with a barrier we eventually break through.

There are so many examples, including the sound barrier which no-one thought could be broken either.

As the kinetic energy and speed of an object increase, then so does its mass (E=mc2).
This suggests that to go the speed of light would require infinite energy...

This does not make sense when you think about the fact that the universe expanded faster than the speed of light at the beginning of the big bang, so its been done before.

Also , if you could have an accelerating spaceship orbiting the solar system with frequent fuel topups, then why would it not go faster than light? and why would its thrusters stop producing enough energy to propell it a little faster each minute?


To me, personally, this just looks like another barrier that human kind is going to eventually break one day. And I don't mean bypass with wormholes, I mean we will take an object past the speed of light one day...

BTW cool theory here :: http://www.space.com/businesstechnology/080813-tw-warp-speed.html

General Science / Is it possible to make an optical microscope that can see atoms?

« on: 24/03/2010 22:49:16 »

Would it be possible to create an optical microscope powerful enough to see atoms?

I do know that the answer is probably no, but then what would we see if we wouldn't see atoms with a very powerful optical microscope??? Would we just see blackness?

General Science / Does sound travel the same speed on all planets?

« on: 24/03/2010 18:21:56 »

Would sound travel at the same speed on a planet with a different atmosphere to earth, like Venus or Jupiter?

New Theories / Using Gravitational Lensing to see further into the past....

« on: 20/03/2010 13:00:49 »

This is my theory of how scientists will be able to see even further into the past by using gravitational lensing in a new way.

OK, so we know that when you see a galaxy that is 2 billion LY away, you can deduce that you are seeing the galaxy as it was 2 billion years ago.

Now suppose you look the opposite way, IE 180 degrees from this galaxy and you find a massive black hole or something with ferocious gravity that is able to create a 360 degree gravitional lense.

Do you see where this is going? Now suppose that black hole is 1 billion LY away, and it is able to comfortably suck in the light rays from our observed galaxy and spit them out again straight back to us. But now these images are not how the galaxy was 2 billion years ago, these images are in fact how the galaxy was 3 billion years ago, hence we can see further into the past by using 360 degree gravitational lensing.

Here is a little bit of simple math to explain the concept....

-Light takes 2 Billion LY to reach earth from faraway galaxy
-travels a further 1 billion LY to reach black hole and get bounced back
-travels a further 1 billion LY to reach earth from the black hole - hence I think this makes it 3 billion LY since the last billion years of travel (towards earth) was the static picture of the galaxy 3 billion years ago...

Please correct me on the math if it is actually 4 billion, im not sure...

Now I'm not saying the way to do this is to find a galaxy and then look for a massive black hole directly opposite, in fact the best way would be a reversal of that process. Also the light would need to strike the black hole on its perimeter so that it doesnt get sucked in but rather spun around and shot out the other side, straight towards earth.
