swords/knives
Development of the Technology
Invented in 14th century by Chinese Chinese guns had no simple machines Europeans created guns with simple
machines Europeans’ guns did more damage European guns change direction/size of
force Revolvers later developed for easy carry
How well science solves the problem
The technology creates lots of damage MA of it is greater than sword’s Simple machines allowed this to be
possible guns are smaller than swords Easier to carry than swords Simple machines allowed this to be
possible
How well science solves the problem
Sometimes the mechanics can be broken Sometimes it is not water proof It is hard to fix yourself Swords have no mechanics to be broken It is waterproof You can fix a sword yourself
InteractionsLife: Guns effect life a lot People are murdered/assasinated with
