$Image by Melikamp, from Wikipedia, depicting a Dedekind Cut. Image shows a line with the first half red and the second half blue, denoting the numbers smaller and bigger than square root of 2, respectively. Annotating the image are several fractions, such as 7/5, 99/70, 239/169 and 3363/2378 which approximate square root of 2. Sitting at the middle, is square root of 2 itself, dividing the two sets of rational numbers.$
