  1. - boy: i love you

    -girl: i love you too!

    -boy: ok my manager is like looking at me so

    yeah.... i gotta go.

    -girl: ok bye

    -boy:bye

     

    2 hours later... the boy drives to his girlfriends

    house

     

    boy walks up to the door and rings bell

     

    -girl: hey! (gives a kiss to her boyfriend)

    -boy:wassup... you ready?

    -girl:um... wait... let me get my bag and we could go ok?

    -boy :-( k

     

    they both watched a movie and ate dinner....

    once they were done eating they headed back to

    the car but before she got into the car...

     

    -boy:wait! can i blind fold you?

    -girl: why??!

    -boy:its a suprise

    -girl: what kind of suprise?

    -boy: a big one

    -girl: okay but only if you promise me that you

    will hold my hand while you're driving.

    -boy: i promise.

    -girl: ok blind fold me...

     

    so they drove off........... and then they stoped.

     

    -boy :-( k we're here!

    -girl: where?

    -boy:wait let me walk you to the place!

    -girl: what place?

    -boy: somewhere! (and gives a kiss to her on

    the lips)

    -girl: babe!...

     

    the boy walks her to the place

     

    -boy: ok.... let me take the blind fold off you

    -girl: where are we?

     

    he takes it off her and she opens her eyes and

    sees the view of the city and at that same

    spot...

    thats where he first asked her to be his

    girlfriend...

     

    -girl: omg.... (tears come down)

    -boy: why are you crying?

    -girl: this is where you first asked me out...

    -boy: what are you doing the rest of your life?

    -girl: (tears come down faster)

    -boy: i wasnt at work when you called me... i

    was planning this whole thing!

    -girl: what thing?

    -girl: (kisses him)

    -boy: look down the cliff..

    -girl: ok..omg..theres alot of pointy rocks

    -boy:yea, there is..(pushes her off)

  2. Yep' date=' it's a joke.:D

     

    In relativity as you go faster;

     

    Time slows down,

    Length shortens,

    Mass increases.

     

    In other words, wierd things happen.

     

    As an object moves away from you at near lightspeed, the light emitted by it moves to the dull, "red" end of the spectrum. If the object was moving towards you, the light would shift to the bright, "violet" end. This is known as Doppler Shift. (This also works with sound. A car engine sounds higher pitched as it comes towards you and lower pitched as it is going away.)

     

    So a stupid idea coming at you very quickly will;

    A) Have a lot of wierd things happen to it. and

    B) Move from the dull, red (stupid) and of the spectrum to the bright, violet end.

     

    Does that help?[/quote']

    Let see if i get it right. Basically, weird things happen when object moves faster than the speed of light, right? those weird things specified by SR are only Time, Length, Mass. And religious people are either misunderstood or are dishonestly applying the theory to some stupid idea that they can come up with, like moral/stupid idea...etc, right? i can't laugh now as i am not sure..hehe.

     

    I am thinking about the idea that you can travel faster than the speed of light, 186,000 miles (300,000,000 meters) per sec. Due to the time difference, when you travel from Boston to CA in the matter of seconds, you're younger than yourself in Boston 3hours. What about from CA to Cambodia? umm...likewise, in the twin paradox, the rocket twin would be younger than earth twin, but how young? age (time) or his appearance? i guess he would look younger. but i've never seen that. :rolleyes:

  3. Well he convinced me! I have seen the light!! I understand now!!!

     

    Morals are only relative if they are moving very fast.

     

    this seems a case of "special" relativity' date=' stupid ideas seem smarter when they come at you really fast.

     

    hmmm. thats going into my sig.[/quote']

     

    That is a joke right? i never studied SR before, can anyone explain this joke to me please..? :confused:

  4. I am attempting to build a working Battery-free flashlight flash light. It would be powered by coils around a pen tube with a rod magnet inside. When you shake the tube the magnet goes up and down reversing polarity inducing a charge in the coils. The only problem is I can’t seem to get more than 0.9 volts out of the thing. I need at LEAST 3 volts. Not to mention that the current output is pitiful. The coils I wound are PERFECT. The layers are on top of each other with no overlaps. There are somewhere between 500 and 1500 turns. I can’t even begin to guess how many.

     

    So does anybody have any ideas? I have attached a schematic.

    I am sorry. i think i response too late here. But why there is a need of full-wave brigde rectifier? why not just use a large capacity to charge more V drop from magnet? anyone pls enlighten me!

  5. No.. how is it your numbers ? Give reasons.. there might just be multiple answers.

    Like i said, something i look at everyday is a mirror, which is what i've seen out of ur hint. So

     

    12,1,1,1,2,1,1,2,1,1

     

    Boldfaced number is the answer based on the reflection of the mirror. ummm...that may be wrong...:)

  6. sure

     

    No-legs lay on one-leg' date=' two legs sat near on three legs, four legs got some.[/quote']

    I don't know much about english vocab, but i can feel the right answer as you gave me the hint that it's similar to this thread. Thus, it's gonna be "fishes lay on dish (or 1 leg plate), a man/woman sat near on 3-legs chair, and a dog got some"...i think it's terrible answer.

  7. It's a person that comes into a room holding a chicken leg' date=' who puts it on a three legged stool and walks out of the room. Then a dog comes in, and picks up the chicken leg with it's mouth. The person comes back into the room, picks up the stool and throws it at the dog.

     

    Is that anything close?[/quote']

     

    Smart!! :D

  8. Okay here is one...

    12' date='1,1,1,2,1,...,...,...,...

    What will be the next 4 numbers?

    Here is a hint. Its related to something you look at everyday.[/quote']:D Something i look at everyday is a mirror, so..

     

    the following four numbers would be 1,2,1,1....

     

    hope it is correct :D

  9. Hmmm... i've read about encryptions and they sound like fun... can someone please explain to me how to do them and perhaps give me an easy one to decrypt???

    I can give u a basic concept of encryption scheme using XOR operator which returns a true value if one, but not both, of its operands is true. For instance in stream cipher, the plaintext bits are xor-ed with the common secret key.

     

    Encryption ( Transmitter Tx):

     

    Plaintext: 00010111

    Secret key: 11001100

    Ciphertext: 11011011

     

    Decreyption (Receiver Rx):

     

    Ciphertext: 11011011

    Secret key: 11001100

    Plaintext: 00010111 (here you go, you got an unencrypted message back.)

     

    However this sort of system is no good as the key is exposed in the process and disclosed some useful information for the adversary

     

    Do more search with the key words like (a)symmetric cryptography..etc (preferrable in wiki).

  10. I found some free useful webcasts and resources (technical white papers) on this website and would like to share:

     

    TechOnline is an educational resources for electronics engineers mostly and alot more in the field of engineering and computer science.

  11. What form is the presentation in? Like is it a powerpoint thing or what.

     

    It may just be easier if you can give a link to the site so that we can look at it. If it's a webpage the directory of the audio file may just be in the source code.

    From a wonderful website Techonline.com you will find it VERY useful, if you're cs and engineering folks.

     

    It is the regular webcasts of popping dialog that you cannot see the code. I was thinking of turning the speaker on loudly and record it back to microphone and use some program to reduce noise :D ...but Dave gave me this Streamripper...i haven't heard of it before..i'll try it and will be back to inform the result.

     

    Thank you the responses. :)

  12. Actually, i'd like to ask the thread starter about possessing psp. I am thinking to buy but not sure what more can i do with it? playing game, watch movie, listen to music, see photo, access to internet (how? is there IE version in it?), pretty much it?

  13. sfn was down for two days and it was driving me crazy...:confused: I enjoy reading some old and new posts here...i've checked it to see if it's up everytime i'm on the net...dang..i think i'mma go crazy if it's down forever... :-(

  14. I am new here, and this probably is the (dumb?) question i would ask, :confused: as to why is the battle of Evolution and ID such a Sensitive and Hot topic, especially in the U.S? What is it so vital out of teaching ID that these religious people/scientists would love so much to see it being taught in science class in public school? Why would they want to invade their teaching in science class? there are plenty of churches or even their houses for teaching it.

     

    Also, in the evolution side, why do scientists not want ID theory to be taught alongside with evolutionary theory? simply it's not scientific? or perhaps they defend the sciene as a whole that shouldn't be lowered or redefined? the latter sounds like this topic is hot because it is the battle of science vs religion.?.

  15. seems like the site just spends a lot of time saying BS... I only glanced through it, but they seem to be concentrating a lot on how the Earth could be hollow, not why the earth can't be solid. It doesn't make for an entirely convincing argument.

    Perhaps they dedicate themselves on studying and proving their theory that planets are naturally hollow. Wait a minute why would they argue for this theory for? i don't understand. well, sounds like i just ran into another BS. :confused:
