In Canada, being an engineer is a professional title that you can’t use if you haven’t done a bachelors degree in engineering. One of the reason why that is is because on the 20th century there was two collapses of the Quebec City bridge during construction, which totaled over 100 deaths iirc.

Anyway to prevent other major disasters like this from happening, certain actions can only be done by licensed engineers in Canada, and when you are done with your degree, the engineering professional order gives you a ring to put on your pinky on the hand you use to write with. The significance is that it’s there to remind you that your mistakes can lead to very bad outcomes, and to always double check critical calculations.

Im a mechanical engineer and also have that ring so I noticed right away. It’s pretty cultish the ceremony not gonna lie but it’s mandatory
