You are living in the year of my birth; I am one hundred years old now, writing to you from the year 2107. I am using the last remnants of the advanced physics that scientists developed during your era, in order to send this electronic message back in time to one of your computer networks. I hope that you receive it, and that it will give you reason to pause and reflect on your world and what actions to take with regard to it. Of myself I shall say only what it is necessary to say: I am a survivor. I have been extremely fortunate on many occasions and in many ways, and I regard it as something of a miracle that I am here to compose this message. I have spent much of my life attempting to pursue the career of historian, but circumstances have compelled me also to learn and practice the skills of farmer, forager, guerrilla fighter, engineer — and now physicist. My life has been long and eventful...but that is not what I have gone to so much trouble to convey to you. It is what I have witnessed during this past century that I feel compelled to tell you by these extraordinary means.
