− | Interferometry is the practice of overlapping two different waves to get a different signal, which can be used to determine the distance between two reflecting surfaces. An {{w|astronomical interferometer}} uses this principle to build an array of separate telescopes that are able to work together as a single telescope, effectively providing higher resolution using a process known as {{w|Aperture Synthesis|aperture synthesis}}. | + | Interferometry is the practice of overlapping two different waves to get a different signal, which can be used to determine the distance between two reflecting surfaces.

In the comic, [[Beret Guy]] and [[Cueball]] are walking Beret Guy's dogs when Beret Guy makes a comment on how interferometry is really cool. Beret Guy states that two dogs placed at a consistent interval will function as a larger dog — a play on the astronomical interferometer. While this idea works on waves, it probably won't work on dogs{{Citation needed}} (though since h/p=λ it might), which is why Cueball is confused and starts to correct him. Before he can respond, however, Beret Guy jumps on his "large" dog and appears to be floating in midair. The existence of a large dog is further proven when it gives out a large bark. Cueball looks on speechless while Beret Guy appears to exhibit another of his [[:Category:Strange powers of Beret Guy|strange powers]]. | In the comic, [[Beret Guy]] and [[Cueball]] are walking Beret Guy's dogs when Beret Guy makes a comment on how interferometry is really cool.

In [[1614: Kites]], Beret Guy is "walking" a dog. It is possible that one of the dogs in this comic is the dog from that comic. | In [[1614: Kites]], Beret Guy is "walking" a dog. It is possible that one of the dogs in this comic is the dog from that comic. | ||
− | The title text states that the effective giant dog is not any more 'good' than the two original dogs. This is analogous to sensitivity for astronomical interferometers. | + | The title text states that the effective giant dog is not any more 'good' than the two original dogs. This is analogous to sensitivity for astronomical interferometers. Interferometery does not increase the light-gathering area, so it cannot view dim objects as well as a single large telescope could. This is also a reference generally to dog-owners calling their dogs "good dog" or "good boy/girl" and possibly to the [http://knowyourmeme.com/memes/theyre-good-dogs-brent They're Good Dogs, Brent] meme. |
