The calculation for magnitude is mag (/ (/ delta-t dist-squared) dist) In the Java code for n-body it is double mag = dt / (dSquared * distance); Which has the nice effect of removing an expensive divide from the inner loop. Doing that & manually inlining the functions in advance! gives me about ~5% faster numbers. Code is at http://clojure.pastebin.com/m46d57338
