Ketarax
editKetarax is an original word and an alias used by a physicist. The word stems are ketara and x, where ketara is Finnish dialect for 'a limb', and x is supposed to concot a picture of the physicist's limbs being stretched out, like an X. This posture, also locally known as 'apinanraivo-äx' ('monkey-rage x'), when assumed during atmospheric freefall yields the maximum decelaration and also orients the falling physicist.
