y = a(1 - r) to the power of x [part three]

I spent a life alone with mathematics. Feeding my diminishing whole with numbers; frantically searching for a different solution. And having failed to disprove the irrefutable, I now regret those years in the narrow halls of academia. The ghost that I am becoming will have nothing but time to remember, and very few memories. 
[To be concluded tomorrow.]

y = a(1 - r) to the power of x [part two]

He told me I was living half-lives and a time would come when there would be nothing left to halve. He then taught me the simple function that would define my life.

y = a(1-r)^x

[Where a is the initial amount before decay began (my whole self), r is the rate of my decay (1/2), and x is the number of intervals (my half-lives).] 
My decline continues rapidly, but the rate of change will decrease over time, as there is less and less to halve. A ghost of me may outlive you all. But that ghost's mass will be so insignificant it will not be able to interact with the physical world. In fact, it is likely that it will fall through the earth to further reduce within its core.

y = a(1 - r) to the power of x [part one]

This morning I awoke to look through myself in the mirror. This new symptom of my singular condition, although long theorized and manifesting on schedule, terrifies me. How could it not? As I type this now I find it difficult to impart the necessary force to depress the keys. I am with increasing frequency disintegrating. These are the last words of a man fading from existence. I will then attempt to be brief, so that I may convey a lifetime of experience in the few moments I have left. 
At the age of fifteen it first became evident that something was terribly wrong with me. While I appeared outwardly healthy and continued to grow in size, I was in fact decreasing in mass. A neighboring mathematician and close family friend, acting on a hunch he would later call insane, began measuring me daily. Over time a pattern emerged and his most outrageous fears were confirmed, I was decaying exponentially.
