Mathematically, a square sensor...

1) Why are camera sensors not square? Surely a square sensor is the most efficient way to get the best out of a lens?

...puts the most sense-cells in a "good place" and would give you a file that you could have more freedom to compose an image. If we assume the center of the image circle is the best in terms of clarity then a square sensor makes sense (no pun...). If we assume that the image quality is equal across the whole of the image circle, then we make the most of that uniformity with a square sensor. Your "dumb question" has got me thinking: it is a very good question indeed.

Best regards,
