Video: In order to harden the edge of steel, swords are often heated until they're impossibly hot and then quenched in liquid to rapidly cool down. This creates a much stronger grain structure in the steel which obviously leads to a much stronger sword. An interesting thing that happens during this quenching process is how the sword dramatically bends before it snaps back into shape (with a slight upward tilt).

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
