    Quantum entanglement , ftl

    I have wondered about this experiment and I come to the following problem. How can bob tell the difference between his electrons before and after Alice measures one of her set? I wonder if a Elitzur–Vaidman bomb tester could be set up to serve such a purpose? I read a paper where they showed it...

    How magnets attract objects mechanically?

    Light is the physical phenomenon responsible for magnetic and electrostatic attraction and repulsion. Light carries momentum from one charged body to another, the direction depends on the sign of the charge. Magnetism is the consequence of relativistic motion (in familiar cases rotational or...

    Bell, EPR, paradox or not

    This is where I have a problem. The average value of the polarization of the "photon" after it encounters the first polarizer can't tell you anything about what happened upstream of it. But thats the average.. not the instantaneous. Angular momentum and everything is conserved, so if a "photon"...

    Bell, EPR, paradox or not

    Thanks for this, but what does 10 or 20 triplets mean in this context? I can't concentrate anymore so I'll have to look at that paper later... Individual values independent of the act of observation meaning that my electron really has a value for its x and y spin simultaneously regardless...

    Bell, EPR, paradox or not

    Finally, it should also not be mystifying that QM doesn't allow us to predict certain things with absolute certainty. It can be proven that any particular theory will always be unable to predict certain things. Bell did this. At the end of the day I'm not really arguing with Bell, although based...

    Bell, EPR, paradox or not

    I have another one. This one is harder to explain so cut me some slack. Imagine two people, Alice and Bob who are color blind. Or rather, that they can only detect brightness of a certain hue, no matter what detector they use. Write the hue that they can detect with a vector (R,B) with R...

    Bell, EPR, paradox or not

    I meant 120° from eachother, not both at +120°. Sorry for that confusion.

    Bell, EPR, paradox or not

    I keep looking at these experiments that demonstrate violation of Bell's inequality and I really can't figure out why anyone cares. The scenario always seems wrong in some way. For example the EPR paradox. The argument goes like this, if you start out with a source of entangled "photons"...

    Quantum mechanics comment

    Even the sum of all histories interpretation agrees that there is only one history. Its just that its the sum of all possible ones...

    Joy Christian, Disproof of Bell's Theorem

    I finally like where this thread is going. I've literally been losing sleep over this for some time.

    Double slit experiement?

    The wavefunction that describes the electron is calculated based on the geometry of the experiment and provides a statistical prediction of which screen locations are more probable than others. The wavefunction is a vector field, and so when two of them are superimposed, the vectors at each...

    Squashing Shot Noise - help please

    How did you connect them in this case? To average the analog voltage I would buffer and Low Pass Filter each sensor and then average them with resistors or an Analog Summer. For the modulation method, obtain a clock signal at an appropriate frequency, perhaps 150k-500kHz and use it to control...

    Wireless Electricity

    Agreed. In the situation I was describing the L and C would be in parallel, just like in a Tesla Coil.

    Infinitely small.

    Its true that direct evidence for this has not been observed, but the current (unconfirmed) theory to which I subscribe states that you can't compress any object that has a non-zero number of microstates (entropy) into a volume bounded by a surface with less area than 4 square...

    Entanglement and Bell's theorem. Is the non-locality real?

    I dont understand what bells inequality is refuting. Why does local realism predict a different outcome? The probability for a photon to pass through a polarizer is the Cos of the angle between it and the polarizer. So if you put a source of linearly polarized photons through a polarizer...
