I just want one person to prove to me how knowing Math and being literate in English (The Lingua-Franca of the world, the lanugage of commerce ) damages the Torah
I think your question is the difference between tahor and kadosh. Math in a vacuum is probably not the issue. Similarly, Math (or biology, astronomy, musical theory, etc.) that is specifically needed for the individual to understand parts of Torah learning might even be a hechser mitzvah for him.
But what about someone whose chelek in Torah is not through understanding the calculations of kiddush levanah? Here is a Yeshivah boy who would otherwise be having class in Talmud but he is now forced to learn geometry. Why is it not bittul Torah for him to learn this subject?
On another level. Why don’t you think that a person whose mind is 95% pure Torah is better than someone whose mind is only 85% Torah and 10% Math. Would you also prefer a diamond that is only 85% pure?
The question is: My purpose is to learn Torah- what will help me do that? Basic addition (for me personally), yes. American History, no. Chemistry, no. Zoology, biology, maybe. English Grammar, no.
I think that is why there are some gedolim of previous generation who did learn specific subjects- to enhance the areas of Torah study they were studying. But not lishem mitzvos yidiyas hamadah.
