We need nanotechnology in order to create a new generation of computers that will work even faster and will have a million times more memory but will be about the size of a sugar cube.
Make a glass of black tea, put in two cubes of sugar, keep stirring the tea until the sugar dissolves, add a piece of lemon and some ice cubes, and you get a glass of pleasantly sweet ice tea!
There's this cube on the screen and it bounces around all day and sometimes it looks like it's heading right into the corner of the screen and at the last minute it hits a wall and bounces away.
