Feet of Sea Water (FSW)
I was pretty rubbish at Maths in school despite giving 101% effort. When this made no difference to my results my mum paid for extra tuition for me. The problem was that I was 14 years old and the tutor was rather attractive. As she tried to explain long division to me all I thought about was multiplication.
I then tried copying my friend Ste’s homework – my results improved………….until the exams. Oh dear……………re-sits. I eventually got a B.
My attitude, shared by others who struggled in this class was one of “when will you ever need to use any of this in real life?!?!!” Well, the fact is, I now have to use it daily and with the help of a calculator, the internet and Microsoft Excel, I get by.
There is quite a lot of maths in diving – all of it critical, but not a lot of it is difficult with one exception – converting into or out of feet to metres. I deem myself average at maths and don’t feel too bad that I don’t know my 0.3048 times table.
