Why isn't this taught in school or university?

"Abraham Zacuto, professor of Mathematics and Astronomy at the University of Salamanca, completed his astronomical tables and diagrams, the Almanach Perpetuum, in 1473. On the basis of these tables two other Jews, Jose Vesuho, who was Court astronomer and physician to John II of Portugal, and the Moses the Mathematician ( in collaboration with two Christian scholars ), discovered the nautical astrolabe, an instrument by which it became possible to measure from the altitude of the sun the distance of a ship from the Equator...
The scientific facts which prepared the way for the voyage of Columbus were thus supplied by Jews. The money which was equally necessary came from the same quarter, at any rate as regards his first two voyages. For the first voyage, Columbus obtained a loan from Louis de Santangel, who was of the King's Council; and it was to Santangel, the patron of the expeditions, and to Gabriel Saniheg, a Marrano, the Treasurer of Aragon, that the first two letters of Columbus were addressed".

Probably because no one cares about what religion someone was

For the same reason why it's not taught that one of the main reasons for Columbus' and others' travels was looking for a way to avoid passing through Muslim-controlled territories when trying to reach China and India. Too complicated for institutions that need to teach simplified narratives.

Jewish identity is not only about a religion.

I think it's more about avoiding anything related to the Jews ( except ancient Biblical times ).
Pointing Jewish role in the slave trade, maintaining of sugar plantations or finances and banking would be seen as 'anti-Semitic'.
Scientists and 'researchers' usually avoid such topics as the causes of anti-semitism, prejudice against Jews, blood libel etc.
