You are the protégé of Wilkins and the only man still living who worked on that project; on his deathbed he passed his mantle on to you. It follows that you are the man best suited to assemble and organize the data that our machine shall require, and to place it in a form that may be read and understood by a machine. This is a matter of assigning prime numbers to the symbols and then encoding them in some medium, probably as binary digits. The medium needs to be something enduring, for it may be many generations before machines can be constructed that are capable of doing the work. Best would be thin sheets of gold.
