What defines a great invention? Most inventions these days tend to be modifications or improvements on previous ideas.
Watching the New Inventors on ABC yields some amusing and often useful new ways of doing something, but I am challenged to actually label the presented results as true inventions.
Was the wheel an invention? Cut a tree up in small cross sections and you have wheels.
Doing a search in Google throws up notable inventions like the Light Globe, the Television, the Wheel Barrow, Glass and lenses, the transistor, paper, the automobile and other things from our past.
What truely life changing and innovative inventions (not modifications) are you able to list that have appeared in the last 20 years?
