“{One of the Charedi parties (Gimmel) has put out an ad banning Euclidian Geometru saying thats its terrible for Yeshiva boys to learn Euclidian Geometry instead of Mishnah”
Did you see the ad?
No you didn’t. You read this on a self-hating formerly Jewish blog.
This ad never existed.
The Chazon Ish was a world -famous mathematician.
It’s high-time you take your hate out of here, and stop feeding us the drek you read elsewhere, all unverified by yourself.
You have been proven wrong so many times in the CR, it’s almost pathetic.
