Belief in God is rational. Everything has a cause. So unless there is a first cause, then you would have an infinite regress. And then nothing could exist. Therefore there must be a first cause. Therefore God, the first cause, exists. QED.

Mathematics and Physics
I think that learning Mathematics and Physics is important even for us dumb people because I consider this learning to be a second degree mitzva. There I such a thing as second degree as you can see in the Rambam that learning Gemara is delving into the depths of the Mishna. In psalms 77 (which is one of the ten that Rav Nachman said were a tikun/correction for damage to the holiness of the brit) it says, “I will recount all Your amazing works.” How to go about learning? The best idea is to say the words in order and go on, until the end of the book and then review the same book four times. Don't worry if you do not understand at first for eventually you will understand by doing much review. And even if you do not, so what? At least you get the mitzvah of learning the works of creation as mentioned in the Mishna Torah
