  1. The whole relativity depends upon the speed of light which is totally electromagnetic. And, photons only do move with the speed of light at a certain space-time position. Is this strange somewhat? Or, photons do move with the upper limit of relativity, speed of light and why?

  2. Determine features available and different, and determine your needs and those fit to you; bounded with the highest cashing......

     

    Don't get confused, you will build a project.... and if you are perfect you will make a difference.

     

    Look to future needs, and don't bother to hards, unless they are blocks.

     

     

    Looking smart, aren't you? :rolleyes:

  3. Memory is proportional to the "square" of the SURFACE DENSITY OF TRANSISTORS. The relation between the rise with time, is because the rise is linked to the capacity itself, i.e. proportional to it.

     

    There are many Computer Theories. I think that what you are talking about is that related in general to the advances in Computer Systems.

    By the way, memory capacities and speeds are now saturating in the already known technologies. New ones need get discovered if present; which is a good question.

     

    Do any one have any idea?

  4. dr.nishanth,

     

    Project design. It is the begin.

     

    The problem is not in the remote control. It is available in market. Just get the output signal in the receiver and control with it motors of the chopper.

     

    Plane's design is madness.

     

    Don't forget..... it will fall....... :(

     

    Solve this problem first. You can do it.

  5. We choose to think when there is a need to think and it is suitable for this. But, some people sometimes think with no problem in hand while being in very hard situation.

     

    If the second sentence is correct, can we believe that "those people are not choosers"?

     

    Will you think? :mellow:

  6. In QED, it is well known that the electromagnetic field is also quantized (related to quantized electromagnetic sources) and that the quantum field is that of the wave function of photons.

     

    But, I am just wondering if photons are deterministic, as confirmed by absorption and collision (Compton's effect). And, if not.... is the wave function of photons can be determined? Is there something mysterious in QED? Can any specialized expert comment?

  7. the mass' date=' when accelerated to relativistic values, changes to energy.

    preferably high-energy. (am i even close on this stuff?)

    [/quote']

     

    We are not talking about high speed. In addition, when a mass accelerates, it doesn't transfer to energy; it is its kinetic energy which increases.

     

     

    high energy energy in the form of electromagnetic radiation, generically speaking, lightwaves have their wavelength shortened.

     

    Then the difference in energy has been emitted, not stored.

     

    correct me on this if it is wrong. the sine-wave described by a photon and its electro and magnetic fields exhibits force fields emanating around it?

     

    Electromagnetic Field exhibits force upon electric charges only, not masses.

     

     

    as theoretical as this sounds, i want a singularity in this universe, obeying the laws of physics.[/

     

    For sure, approximate singularities do follow the laws of physics. See how delta dirac function work in General Relativity.

  8. I think that changing the definition of "Classical Phyics", which is now: "Vector forces, gravity, acceleration, and other facets of mechanics.", to include EM. The name is "Classical Physics" not "Classical Mechanics".

     

    May be these definitions are to be written in the first page.

     

    "Physics" Section also contains general threads. So, the classification is good and involves all types of physics.

  9. It is included in "if(x>y)". This compares the MIN Term for each of the 2 new elements, that are under consideration. In other words, it puts element A in S1 and element B in S2 and calculates the MIN Term (int x=MIN(2L)), then make the opposite and recalculate the MIN Term again (y=MIN(2L+1)). The correct classification is the one that gives the least MIN Term.

     

    Note: xs is S1 and ys is S2.

     

    Is it clear?

  10. An increase of energy of what? You are saying that mass has transformed to energy.... what type of energy?

    I suppose you are talking about Gravitational Potential Energy between the particles of the star. If the particles become closer to eachothers, then the total Gravitational Potential Energy between particles will decrease more, resulting in emitted energy. But, how this energy becomes stored in a singularity?

     

    A theoretical singularity may form due to the contraction of some mass in a point, or even a sheet. Is this what you are talking about?

  11. For MIN(n), we can have the following algorithm. I think it may also work for MIN(0).

     

    //(given: set M with n integers)

    sort(M); //M(0)<M(1)..<M(n-1)

    ys(0)=M(0); xs(0)=M(1)

    for (int L=1; L<(n/2); L+)

    {

    int x=MIN(2L), y=MIN(2L+1);

    if(x>y) ys(L)=M(2L);xs(L)=M(2L+1)

    else xs(L)=M(i); ys(L)=M(2L+1)

    }

     

    This is based upon the procedure I introduced. Feel free to ask any question.

  12. I was saying that although we don't see any light coming from a black hole, there is radiation of light from the star within the event horizon, i.e. inside the event horizon there will be light seen coming from the star. The light only "gets delayed" at the event horizon........ that's what I meant by "prisoned".

     

    Although there is nothing that can escape from the event horizon from the inside, still a particle, or light, MAY enter from outside to the inside.... but the path must have some properties for that to happen.

  13. If the Time Intervals are tending to zero, as time increases, then the summation MAY be finite.

    You have for example the geometric sequence; the sum of infinite number of terms is equal to a/(1-r), where a is the first term and r=Term(n)/Term(n-1), but r must be smaller than 1 for the summation to converge.

  14. Yes, toastywombel, D-branes are features of M-Theory. And, as you said, strings are connected to these D-branes. Doesn't this imply that they can exchange energy through the branes?

     

    And, I am wondering if closed strings can loose or gain energy sue to some factors. Do have an idea?
