I have the following questions about the above circuit:

-Why are we even using a trica/diac combo above. Why would a circuit consisting of just the fuse, switch and primary not be sufficient for charging the battery?

-If we do go ahead with the above combo, what is the use of the resistor/capacitor combo attached in parallel above the triac?

Thanks

Question: Quantum entanglement as practical method of superluminal communication
Answer: This 'spooky action at a distance' will not and can not lead to communications technologies. The point is that the correlation between the two states cannot be used for information transmission. The two observers can influence each others' observations, but they can never communicate their own observations to the other superluminally, and thus will have no way of checking who influenced who (before waiting for subluminal information transmission devices), rendering the correlation between the states useless for all communications purposes.
