... For the main part, that means turning vectors in 4_vectors. Which means at least to find the “time component” of the 4-vector. Starting, as usual, from the simplest case. And the simplest is: the “position vector” (x,y,z). In this case, the answer is obvious, since this is where it all started: The ...

How do you know if a quadratic equation will have one, two, or no
... How do you find a quadratic equation if you are only given the solution? If you only have the solutions to the quadratic equation, you can reconstruct the equation in the following manner. Suppose that “m” and “n” are the solutions. Write the equation: (x – m)(x – n) = 0 and substitute the given val ...

Extending SDL and LMC Complexity Measures to Quantum States
... Consequently, these two simple systems are on the extreme of the scales of order and information implying that a convenient definition of complexity should be proposed combining order and information [11]. Starting with the association of disorder and entropy representing thermodynamic equilibrium, ...

This phenomenon is called “Brownian motion” and reveals very clearly the statistical fluctuations which occur in a system in thermal equilibrium. There are a variety of important situations which are basically described by ...
