The first travellers rocket-blasted from the earth will experience the mule-kicks of acceleration. Then they will experience the mosquito - bite irritations of a gravity-free existence in a cramped spaceship. Let us review the seriocomic aspects of trying to live without gravity. Picture yourself in a gravity-free spaceship. You're seated at a dinner table with a meat, platter and glass of water before you. You're thirsty. You raise the glass to your lips, accelerating it in the process. As the glass reaches your lips you decelerate it to a stop. The water, however, is not fastened to the glass. October 30, 1955.
