BAM
A lot of these were difficult decisions, especially when one thing is a component of another (what's more important - gunpowder or the gun itself?). I did my best to research the ones that I didn't really know much about. I have a rudimentary knowledge (read: 1 semester) of engineering, so hopefully I did all of the scientific inventions some justice. For the record, I tried to judge based on the initial impact of the item, how useful it is today (has it been upgraded? is it useless in today's society?), how many substitutes there are, etc. Some things I didn't even really think were inventions. They were given 1 point.
FLAME/DISCUSS AMONGST YOURSELVES. If someone convinces me otherwise, I MIGHT change my score.
