Jewish physics

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 a mere 1% 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 a probable basis for the Polandball cartoon in thich Germanyball destroys Israelcube after the latter mentions its discovery that countries are actually 4-dimensional hypercubes, not spheres.
