PLAYING A RECORD? I'LL TELL YOU SOMETHING INTERESTING; COMPARE A POINT ON THE LABEL WITH A POINT ON THE RECORD'S OUTER EDGE. THEY BOTH MAKE A COMPLETE CIRCLE IN THE SAME AMOUNT OF TIME, RIGHT? BUT THE POINT ON THE RECORD'S EDGE HAS TO MAKE A BIGGER CIRCLE IN THE SAME TIME, SO IT GOES FASTER. SEE, THE POINTS ON ONE DISK MOVE AT TWO SPEEDS EVEN THOUGH THEY BOTH MAKE THE SAME REVOLUTIONS PER MINUTE!
