As a Stonemason, this shit always bothers me. Recent example was an article on stone henge. "Scientists still mystified as to how the stones were stood so that to caps were level!"

Mfr! Give me a straight piece of wood, a length of string and a rock, I will make you a basic level. Don't want to lift the stone in and out multiple times to adjust the level? Get logs and cut them to the same length as the upright stones. It's not fucking rocket surgery!
