Week 16 Inventions

I learned about four inventions this week: chess, the arquebus, the printing press, and the mainspring.

The first invention is chess.  Chess is a game that is played by two people and helps teach strategy which I think is very fascinating because very few games like that were played back then.  It had an impact on history because people played chess instead of dueling; therefore, less people were killed.

The second invention is the arquebus.  The arquebus is a hand cannon which at its simplest is a barrel plus a handle.  It impacted history because it inspired the musket and rifle.

The next invention is the printing press.  The printing press is like a giant stamp with little letters on it.  It impacted history because copies of books could be made faster which resulted in thousands of books for one to read which also meant better education.

The last invention is the mainspring.  The mainspring is a thin, long piece of tempered steel wound tightly into a coil.  It impacted history because the mainspring made portable clocks posible.

To recap, chess, the arquebus, the printing press, and the mainspring all had an impact on history.
