# Facing Jerusalem while davening

In a 3 Dimensional geometric structure like a sphere, you can "stand" at any point 'A' and continuously be facing another point 'B' in question. You can stand on the beach of long island and be facing Japan. You can also turn around 180 degrees, facing away from Japan, with your back towards Japan and you will still be facing Japan ( via Pennsylvania > Oregon > The Pacific Ocean > Japan ).

In that case why can't we fulfil the requirement of facing Jerusalem, by turning towards ANY direction, since you can draw a line from your location to Jerusalem; under all possible geometric scenarios?

• Similarly, why was anyone offended when Donald Trump turned his back on Queen Elizabeth II since he was really still facing her the long way? Oct 16, 2022 at 16:27
• See: chabad.org/library/article_cdo/aid/3502321/jewish/… where the article cites the Levush on Orach Chayim 94. - There are two potential ways to calculate the distance between two points on the globe. The first way is to project the globe’s surface onto a flat plane (Mercator map) and basically follow the straight line drawn on the map (“rhumb line” or “compass route”). Oct 17, 2022 at 17:07
