One of the best aspects of 2001 was the silence allowed for scenes in the vacuum of space. The time given to those scenes also enhanced the intended spatial effect. Today, such "empty space and sound" would fall, cut to the editing room's floor.<BR><BR>Kubrick and Clarke created a masterpiece, however, from

Since the pod is not fixed to Discovery, the forced blowing of the pod's hatch should have pushed it away.<BR> * In the airlock scene, Bowman is seen holding his breath before being ejected from the pod craft. Before exposure to a vacuum, NASA states, the person must exhale, because holding in the breath would rupture the lungs.[29] (See also vacuum.)<BR> * When Dr. Floyd is flying to the moon, weightless, he sips food through a straw, yet when he lets go of it, the fluid falls back to the container, showing that the fluid in the straw is not weightless.<BR><BR>The Centrifuge in Discovery One — Exercising astronaut Frank Poole jogs its circumference.<BR><BR> * Though the crew quarters in the spaceship Discovery are arranged in a rotating wheel to simulate gravity, the wheel's short radius would require many RPM (5-10 RPM, depending on the actual radius) to produce Earth-like gravity. In the film, the centrifuge rotates at about 3 RPM (once every 20 seconds).<BR> * In the Pan Am Clipper, the stewardess grabs the sleeping Dr. Floyd's pen as it floats in zero gravity. The pen is rotating, but not on its own center of mass; it is rotating on an external center.<BR> * In many scenes, the stars move past the spaceships while the camera keeps pace with the ship; impossible unless the ships were traveling extremely fast or they were turning.<BR> </div></BLOCKQUOTE> <BR><BR>Not even considering when the movie was made, it still ranks as my favorite sci-fi ever.
