The Original Double Slit Experiment
Why Hacker News recommends it
HN cites it in double slit debates for its grounded demonstration of interference as classical wave behavior.
What it is
Veritasium revisits Thomas Young's original double slit experiment with light, showing how interference supports the wave nature of light. It uses a pond-wave demonstration to explain the pattern.

Here's the important part of the video, in my opinion: [this video] Basically, two floating balls are used to create waves on the surface of a pond... From the waves created; from their interference patterns on the surface of the pond, we can see exactly how light behaves in the double-slit experiment.

I just stumbled upon Veritasium a week ago while learning about the double slit experiment in quantum theory and trying to see some actual evidence [1] of the experiment. [1]: [this video]

> We speak of "noise" (interference) Note that interference here has a very technical meaning that is NOT noise. (Sorry for the all-caps, but it's very important in these experiments.) I think you don't understand the important point in the double slit experiment. Let's try to explain it, but it's a long explanation. --- First you must understand the single slit experiment. If the slit is thin enough you get a nice diffraction patter. If this spread was caused by dust or something like that, a good guess is that the image gets a gaussian blur like exp(-x^2). In a diffraction experiment, the image you get is something like sin²(x)/x². (You should draw them in Wolfram Alpha or something.) The
