@HGourlayUCL @martinvermeer Yes. I get that and that is because there is little joining of the dots at exam board level. Physics, chemistry and maths all seem to do things slightly different. Maths focuses on decimal places all the time while SF are never properly grounded in the sense of confidence - how much money/chocolate would you bet on the last, the penultimate, the penpenultimate, and so on, figures being correct!
I worry that it's a zombie problem that will keep recurring…

@sellathechemist @martinvermeer I think there are two ideas coming up in this discussion. One is about having a feel for the approximate size of the value calculated. Does this seem about the right size? The second is about certainty/uncertainty. How sure can we be that this value is correct?
