I don't think that language is a major obstacle in understanding scientific explanations. Especially when online translators are freely available.This lecture explicitly show double slit experiment as an example of interference, and single slit experiment for diffraction.What would you expect from a guy who can't spell diffraction?
"Sufficiently" is what it's all about. See Heisenberg!The universe could be infinite, both in space and time. Simulating it with infinite precision and accuracy would need infinite computational resources, which is not practical.
In this video, I describe the process of Fraunhofer diffraction (also known as far-field diffraction) in terms of the Fourier Transform and Fourier Optics. I go over the assumptions that underlie Fraunhoffer diffraction (both the paraxial approximation and the small-aperture approximation), and give the mathematical form that it takes.
This is part of my graduate series on optoelectronics / photonics, and is based primarily on Coldren's book on Lasers as well as graduate-level coursework I have taken in the EECS department at UC Berkeley.
In this video, I go over one-dimensional single-slit Fraunhofer diffraction. I walk through the mathematics using the Fourier Transform to calculate the intensity at a screen a distance d away, as a function of the screen coordinates.You can have a perfectly valid mathematical model. But to be useful, it should reproduce observed experimental results without excessive ad hoc assumptions.
In Ireland when changing down in a manual the recommended method is to lightly touch the brakesAs far as I know that's not written in the "highway code" booklet (for the mainland UK) or generally expected - but I have once had such advice from my driving instructor.
