In mathematics, two lines are orthogonal if they intersect at right angles. More generally, two concepts or situations are orthogonal if they do not substantially overlap. In Israel today, many worlds seem to be orthogonal, either existing separately from each other or having cross purposes. This is true of the relationship between much of the media and the government, the attempt of Israelis to maintain normality in daily life, and the view of Israelis and most of the World about the hostages and Hamas.
