Sci-Tech Science and Judaism

(6) When the woman saw that the tree was good for eating and a delight to the eyes, and that the tree was desirable as a source of wisdom, she took of its fruit and ate. She also gave some to her husband, and he ate. (7) Then the eyes of both of them were opened and they perceived that they were naked; and they sewed together fig leaves and made themselves loincloths.

We must first form a conception of the Existence of the Creator according to our capabilities; that is, we must have a knowledge of Metaphysics. But this discipline can only be approached after the study of Physics: for the science of Physics borders on Metaphysics, and must even precede it in the course of our studies, as is clear to all who are familiar with these questions. Therefore the Almighty commenced Holy Writ with the description of the Creation, that is, with Physical Science; the subject being on the one hand most weighty and important, and on the other hand our means of fully comprehending those great problems being limited.

(1) At the time that the Holy One created the first man, He introduced him to every tree in the Garden of Eden, and said to him, ‘See how wonderful and pleasant these trees are. And all of this I have created for you; therefore take great care that you do not damage and destroy My world, for if you do there is no one else to put right what you have destroyed.’

Rabbi Shimon ben Pazi said that Rabbi Yehoshua ben Levi said in the name of bar Kappara: Anyone who knows how to calculate astronomical seasons and the movement of constellations and does not do so, the verse says about him: “They do not take notice of the work of God, and they do not see His handiwork” (Isaiah 5:12). And Rabbi Shmuel bar Naḥmani said that Rabbi Yoḥanan said: From where is it derived that there is a mitzva incumbent upon a person to calculate astronomical seasons and the movement of constellations? As it was stated: “And you shall guard and perform, for it is your wisdom and understanding in the eyes of the nations” (Deuteronomy 4:6). What wisdom and understanding is there in the Torah that is in the eyes of the nations, i.e., appreciated and recognized by all? You must say: This is the calculation of astronomical seasons and the movement of constellations, as the calculation of experts is witnessed by all.

ויורהו ה׳ עץ וישלך אל המים, “the Lord taught him about a certain kind of wood, and he tossed it into the water;” although G-d had other means of making the water sweet, without using that kind of wood, G-d wanted to teach Moses some common chemistry, i.e. how to use natural products to sweeten something that only needs sweetening in order to make it drinkable or edible.

One day, he was walking along the road when he saw a certain man planting a carob tree. Ḥoni said to him: This tree, after how many years will it bear fruit? The man said to him: It will not produce fruit until seventy years have passed. Ḥoni said to him: Is it obvious to you that you will live seventy years, that you expect to benefit from this tree? He said to him: That man himself found a world full of carob trees. Just as my ancestors planted for me, I too am planting for my descendants.
