technological history

In the past we had focused all our knowledge into moving forward in the world  always trying to be more advance then the competing country's. when the 1900's rolled around people where all about inventing things, things that have never even been thought of before. in 1910 the toaster was made as well as the oven and the washing machine. Shortly after world war 1 started in the year 1914. Even though war is shunned upon it has great potential for inventing stuff.  Because all our money and resource are going into winning it  having more advance technology then the enemy can really help turn the tides in our favor. For instance during the war hydrophones where invented which was pretty much sonar just the poor mans version until later perfected. With breakthroughs like this it has allowed us to get to where we are today. Lately though it seems we have lost focus on what is important and and are spending to much time finding a way to make Facebook better.
