Jewish Physics is a somewhat common running gag in Polandball that jokes about the racism of German scientists during the Nazi Era of Germany. It originated with a comic (seen below) created by an anonymous user of Krautchan. This comic is one of the earliest comics in Polandball, and it is the origin of Israelcube's distinct shape.
In the late 19th century, many mathematicians began exploring abstract geometry and created concepts such as hypercubes and other polytopes. Many of these advancements originated from Germany and, despite representing less than 10% of the German population before World War II, Jews constituted 1/3 of all mathematics professors in the country. A branch of German nationalism known as Deutsche Physik opposed the influence of Jewish mathematicians; notably, German physicist Philip Lenard began a campaign to label Einstein’s relativity theory as "Jewish physics".
This historic German hostility towards “Jewish physics” is the basis for the Polandball cartoon in which Germanyball destroys Israelcube after the latter mentions its discovery that countries are actually 4-dimensional hypercubes, not spheres. The same goes for Russiaball when thinking the Jewish Autonomous Oblastcube is a homo after he thanks him for making a place where Jews can live without being bothered.
When discussed online, it is common practice that the question "Why is Israel a cube?" is answered with "Jewish physics" (perferably) in caps and nothing else. This response is given both as a group habit and because those responding do not themselves know why Israel is a cube, if not simply for its comedic value.

This redditor comic is totally incentered on the Jewish physics, because the time machine is Jew-made
