At work, 11 year olds were issued with Gideon’s bibles today. They looked puzzled, though some said you can use them to help with problems in life. There is a sort of key in the front where problems are listed giving passages to read.
My problem was- can they go into the recycling bin, or should we drop them in the normal land-fill rubbish? It hangs on whether the cover is real leather.
Later: After work was filled with trying to use Excel to decrypt a text string. A nice problem to work on. I didn’t know enough about arithmetic progressions to write the formulae quickly. A good problem to try, I like the feeling when puzzling over things like that.
