I uploaded this video, a excerpt from Jim Burke's "Connections" series (Episode 10, "Yesterday, Tomorrow and You"), to explain one reason why people in general (because we've been taught in our schools this way) tend to think in "straight lines" and thus fail to see connections between inventions, isolated innovations brought about by not one, but dozens and even hundreds of individuals.
Watch the video here:

This post is somewhat a direct reply
against posts/threads like "Great Filipino Inventors" in this subforum, and I hope this video will enlighten the unaware and enrich our ability to be critical thinkers.
