Mathalicious: About Time

How has the pace of human innovation changed over time?

It took 260,000 years for humans to go from the spear to the bow-and-arrow, but only 42,000 years to go from the bow-and-arrow to the atomic bomb.

Students order and subtract integers to explore major milestones in human history and debate whether humans are innovating faster than we can keep up with the consequences.
