Tug of war, for example, is a dramatized struggle between natural forces; knucklebones were once par...

 Fun Computer Science Tasks

C is a big language with a lot of features, and it’s easy to get lost in how fun it is. But you can’t really appreciate a feature without knowing what it’s like to do without. So do things with limited resources. Make a binary adder using falling dominoes. Make a functional digital clock with neon bulbs, resistors, capacitors, diodes, wires, and a wall plug. Make a Turing machine with LEGO blocks. (Use a crank to run it.) If you’re really ambitious, make some logic using fluidics with a rou...
