  1. Can global warming be attributed to the large increases in processes in today's world that produce heat. Every day things such as transporation, A/C, creation of electricity, all produce heat. Can this be linked to global warming?

     

    I think that's okay for the most part, though there are other factors that contribute to global warming besides our world's processes (e.g. cow burps).

  2. ... I turned my spare into a linux box... I like the linux environment better for programming

     

    I've got an old comp sittting here too.

     

    When you guys say linux box, what exactly to you mean?

     

    Just a comp. that runs Linux-based OS or something else?

     

    My old comp's got:

     

    AMD K62 350 MHz

    3.2 GB HD

    32 MB ram

    4 MB video card

    36X reader

    floppy

     

    HOwever, it's still got Win98, and there's only ~200 mb of space left on the HD. I've heard of people doing dual boots with Win & Linux by partitioning their drive from the get-go, but can I still partition it to do a dual boot? More importantly, will Linux run on < 200 mb?

  3. I know bloodhound' date=' but, as I have come across physics for several years, I have never face a problem to manipulate those algebraic symbols in this way... the subject v[sup']2[/sup] does not make sense to physics, why would I find something like the square of final velocity?

     

    so, there must be something more in its background, since it is not just algebraic manipulation that you just come accross naturally, but it's an equation that many textbooks taught!

     

    Any body?

     

    Albert

     

    Why can't the square of the final velocity exist?

     

    As a corrolary, what happens when you isolate for final velocity?

     

    If you like these sorts of things, then look up kinematics. There's much more where that came from. More specifically, dynamics and such.

     

    It gets even more interesting when you use seperation, integration and such.

     

    Enjoy!

  4. I'm a bit lost from step 3 --> 4. How is the result of the measurement sent to ion C? Or is that the nature of entanglement?

    The measurement result can be sent any way you want - digital signal along an optical fiber; carrier pigeon. It's because this communication is necessary that means that no information exceeds c. The entanglement is the "tie" between the two original particles.

     

    :confused:

     

    I still don't understand this part.

     

    So ... does ion B call ion C on it's new cell phone and say: "hey, I've been detected as +1/2 now, you've got change to -1/2 now" ?

  5. ... once the measurement (presumably of the spin of the ion) is sent to ion C' date=' how does ion C recieve that? like if you just shoot data waves (e.g. radio waves) at an atom it wont interact, but yet in this case it does, so why does ion C recieve and 'appl'y this information to itself?

    or is it easier just to say this is what entaglement is!?[/quote']

     

    That's my predicament as well.

     

    What is it in the measurement from one that changes the other?

    Or is that the weirdness about entanglement?

  6. Well, I don't have the answers to you questions 5614, but I've got some of my own.

     

    ...and then change it, nothing happens to the other particle, because they are no longer entangled.

     

    Step 3: One ion from the pair - in this case B - is entangled with A and both are measured

    Step 4: The result of the measurement is sent to ion C and the tranformation implemented

     

    I'm a bit lost from step 3 --> 4. How is the result of the measurement sent to ion C? Or is that the nature of entanglement?

  7. I hate it when people use the term Engineering where it should not be.

     

    What is it that you are engineering with Social Engineering?

     

    Engineering deals with tangible items.

     

    As for those social topics you talk of, I won't bother, as that is not my field.

  8. this MAY need some explaining for those not into digital logic or Boolean.

     

    2 b

    +

    ---

    2 b

     

    the line above the second "2 b" is inversion" (NOT)' date=' the + is the logic symbol for OR.

     

    "to be or not to be".[/quote']

     

    hehe

     

    My friend showed me a variation of that:

  9. How about when solving movement questions.

    What's the acceleration of the car?

    -3m/s' date='-5/s[/b']

    It's -2m/s^2 or 2m/s^2 towards the negative direction.

    So related to negative and positive questions?

     

    I don't understand.

     

    Negative/positive questions?

  10. Last year I had planned on reading the Oddessy but I was forced to read a book called The Giver. It was actually very good. The plot is based around a utopia in which the people are lacking something but they don't realize it.

    I suggest it for those who find philosophy interesting. :)

     

    heh

     

    I cheaped out & read it @ sparknotes

     

    :P

  11. In practice, you're never going to be asked to do this. At most, you'll be asked for a 3D equilibrium point. For larger dimensions, it's better to use something like Mathematica to solve the equations for you.

     

    Speaking of Mathematica, I remember you praising it alot over SFN.

     

    What's a better program overall: Mathematica or Matlab?

  12. Any of Serway's Physics for Scientists & Engineers textbook is great for novices and aspring Scientists/Engineers alike.

     

    **I thought the point of this thread is to suggest books to each other :P

    **So I'll do it anyways: Michael Moore's Stupid White Men is quite a good read atm.

  13. Don't forget to get the essential extensions listed in one of these ff threads! AdBlocker is essential.

     

    AdBlocker?

     

    Is it a seperate ad-blocking program or the default one with ff?

     

    In any note, the default one is sufficient for me.

     

    One more thing: is the upgrade to Version 1.0 of ff good?

  14. buts thats only for [math]x \in \mathbb{R}[/math] . there might still be a solution where [math']x \in \mathbb{C}[/math]

     

    What does the C mean?

     

    [edit]

    n/m

     

    Does it mean complex?

    :P
