Understanding Superposition Physically and Mathematically What is superposition Superposition is a fundamental concept in physics and mathematics, particularly in the fields of wave theory and quantum mechanics It describes how multiple wave-like phenomena can combine or interact with each other In physics, superposition can be summarized as follows: Wave Superposition: When two or more waves overlap in space and time, the resulting wave is the
Schrödingers Cat and the Qbit - Physics Forums The concept of quantum superposition (or superposition for short) is very counterintuitive, as Schr o dinger noted in 1935 writing [1], “One can even set up quite ridiculous cases ” To make his point, he assumed a cat was closed out of sight in a box with a radioactive material that would decay with 50% probability within an hour If a radioactive decay occurred, a deadly gas would be
(A bit for fun) Putting a Human in Superposition - Physics Forums The discussion explores the theoretical concept of placing a human in a state of quantum superposition, acknowledging the absurdity of the idea while examining its implications for understanding quantum mechanics (QM) Participants consider scenarios where isolation from external interactions, such as being in a supervoid or a Faraday cage, might allow for a human to theoretically achieve
How is superposition demonstrated? • Physics Forums Again, how is that sort of superposition demonstrated? The SA article wasn't particularly clear on that point, but I think it might be detected via the same circuitry by which the superposition was set up in the first place
Does Superposition Theorm Apply to power? • Physics Forums The superposition theorem does not apply to power, as it is only valid for voltages and currents Total power dissipated in a circuit cannot be determined by simply summing the powers from individual sources Superposition can be utilized to calculate voltage or current, which can then be used to find overall power In the phasor domain, while individual powers can be calculated, they cannot
Superposition of eigenstates in QM - Physics Forums I am having trouble understanding the subtleties of this topic, which we've just covered in my QM course I guess, if I understand correctly, that the superposition of eigenstates is not necessary an eigenstate itself, unless the states are degenerate I'm not sure if I really understand why
How do I know when to use the Mesh Current Method or Node Voltage . . . These two methods seem like they can be applied to the same situations, and I don't really know when I should apply one over the other I've only just learned the methods so I'm not very familiar with either though I'd appreciate any help from general guidelines to specific examples
