This blog is called "Mah rabu", Hebrew for "how many" (as an exclamation, not so much as a question). Ultimately the significance of this phrase is up to the reader, but the source is Psalm 104:24 - Mah rabu ma'asecha Adonai, kulam b'chochmah asita, mal'ah ha'aretz kinyanecha. JPS translates it "How many are the things you have made, [God]; You have made them all with wisdom; the earth is full of Your creations."
Psalm 104 (Bar'chi nafshi) is in the liturgy for Rosh Chodesh, each time the moon completes an orbit around the earth, and 104:24 is in the liturgy every morning, each time the earth completes a rotation on its axis.
Psalm 104 is the physicist's psalm. It describes a universe ordered by natural physical laws, with elementary constituents combining into complex systems. Where Psalm 29 expresses amazement at thunder and cataclysm, Psalm 104 expresses even greater amazement at the usual state of equilibrium and stability.
Once I saw a license plate that said "PSLM 104", and my initial reaction was that the Progressive Student Labor Movement had raised its demands to $10.4/hour from $10.25.
