Ah, the uncertainties section! Absolute is the ± value from your instrument, like your ruler’s smallest marking. Fractional is that error divided by your measurement, and percentage is just that fraction made into a percent. It feels very precise, no?
Just last night, I was helping my Appa calculate his medicine dosage—the syringe has an absolute uncertainty, but when you convert it to a percentage for his tiny dose, it looks tumba scary. That’s when these numbers stop being just textbook.
