Spatially, the patterns extend to infinity, although with quickly dropped magnitude for further distances. While dark regions within finite distances might be interpreted as products of destructive interference.Based on the radiation patterns that we can measure for various shapes of antenna where we can control the motion of the electrons, we can calculate backwards to infer how electrons should move around the nucleus to produce radiation patterns resembling known atomic orbitals. It will require adequately accurate and precise electrodynamic model.
Unlike in a dipole antenna where the movement of electrons is confined in one dimension, the electrons around atomic nucleus can move in three dimensions.
Wavelet transform is an invaluable tool in signal processing, which has applications in a variety of fields - from hydrodynamics to neuroscience. This revolutionary method allows us to uncover structures, which are present in the signal but are hidden behind the noise. The key feature of wavelet transform is that it performs function decomposition in both time and frequency domains.
In this video we will see how to build a wavelet toolkit step by step and discuss important implications and prerequisites along the way.

Depends on its purpose. If you want to replace yesterday's screw with one made today, yes, it is important that the thread standard hasn't changed, but if you want to privatise the water supply, you have to alter the standard so that every investor can make a profit and pass on the cost of achieving adequate sterility to the customer.Even making good standards is just an instrumental goal, serving to help achieving the common terminal goals among the users of the standards.
Even if it were finite, you can't simulate it completely because the simulation would then be part of the universe, leading to an infinite recursion.Complete simulation is not necessary. It's adequate when the simulation can help prevent major catastrophic incidents. In local application, it's enough when the simulation can help pursuing our goals more effectively and efficiently.
I searched and found this formula in quora.What if there is another twin travel to the opposite direction with the same speed? And another one in perpendicular direction?The formula for perpendicular velocity addition is:
https://en.wikipedia.org/wiki/Velocity-addition_formula
In our case, vx=vy=0.866c.
For convenience, I used spreadsheet to calculate.
putting the number to the left formula gives 0.247c
putting the number to the right formula gives 1.732c
Either result doesn't seem to be correct. It shouldn't be slower than the individual velocity. It shouldn't be higher than c either. Can someone show where the error is?
...Plugging in the value, where vx=vy=0.866c, v is 0.968c.
This messy matrix is not a Lorentz boost. It is, in fact, a combination of a Lorentz boost (corresponding to some velocity in the x−y plane) and a spatial rotation (again in the x−y plane.)
However, at least we can get the magnitude of the resulting velocity from this matrix, as the upper left component of the matrix is not affected by the spatial rotation. It is determined purely by the Lorentz boost. A little bit of trivial algebra tells you the magnitude:
v=√(vx^2 + vy^2 - vx^2.vy^2/c^2)
