My uncle recently passed away* and it fell to me to sort through all his papers. Most things I came across were just old documents, bills, manuals, private correspondence, maps... that kind of thing. But one thing stood out.
Among all the paperwork I found what looks like a set of instructions written in my uncle's hand, lavishly spotted with coloured dots, arrows and other symbols (see picture below). I have no idea what they mean.
I remember my mother once telling me that my uncle was a vaccinologist, and that set my mind to wondering - is this actually some kind of secret formula for a new vaccine or medicine, something to combat a rare disease? Or is it just coded instructions for how to operate the washing machine?!
Please help me work out the significance of this mysterious instruction manual! (Especially what he meant by the last instruction...)
* NB He didn't - the whole set-up here is fictitious. Please send your condolences to people who need them! :)
