How a Windmill Grinds Flour

A windmill turns moving air into turning stone. The sails are set at a slight angle. Because of that angle, wind pushing on them cannot pass straight through, so it pushes them round instead. The sails turn a horizontal shaft. A large wooden gear on that shaft meshes with a smaller one on an upright shaft, which turns the millstones below. Because the smaller gear has fewer teeth, it spins faster than the sails do. Four turns of the sails can mean twenty turns of the stone. The grain falls between two stones. The top stone turns; the bottom one does not. The grain is crushed between them, and flour comes out at the edge.

  1. 1. What does "meshes" mean here?
  2. 2. How are the sails set?
  3. 3. Where does the flour come out?
  4. 4. What is a "shaft" in this text?

Morse Code

Morse code turns every letter into a pattern of short and long signals: dots and dashes. The commonest letters were given the shortest patterns. E is one dot. T is one dash. Q, which is rare, is dash-dash-dot-dash. Because of that choice, an average message is much shorter than it would be otherwise. A message can be sent as sound, as light, or as taps on a pipe. That is why it survived so long: it needs almost no equipment. Timing carries the meaning. A dash is three times as long as a dot. The gap between letters is three dots long, and between words, seven. SOS was chosen because it is easy to recognise: three dots, three dashes, three dots.

  1. 1. What is the Morse pattern for SOS?
  2. 2. What does "frequency" mean when talking about letters?
  3. 3. How long is a dash compared with a dot?
  4. 4. What does "survived" mean in this text?
