engineering for beginners

We see your investigators have uncovered more details about how the early mortals used to live.

Looking at the stones used for tool making at one site around one hundred thousand years ago the investigators realised the stones had been heat treated to make it easier to split off the sharp flakes used as cutting tools.

But what the investigators can't see is that while those early engineers were working on the relationship between variables such as temperature and time and stone sizes, the early marketing people gathered round to talk up the tribe's new process for making the local stones fit for purpose to ensure a bright new tomorrow.

It amuses us to see that some things never change.
