The other day I was looking up information about various ideas and discoveries over the last few hundred years. When I looked at information from 50-100 years a go it is difficult to find accurate information on how long it takes something to go from idea to invention. There are also many times something is listed as being invented by one person, but something better being invented by someone else. As i am thinking of submitting some of my ideas, I would really like an idea of the timeline of invention so I can gage when would be the best time to submit them.
