  Nice question….Well it depends on the situation on the island…..To select food i would read the biology, to cook it i would read chemistry….and for making a boat and running away i would study physics…but i feel the best use of these books on an island will be to use them as a fuel to light up a bon-fire to make myself warm and roast some marshmallows…..
