# Survival Formula

The **Survival Formula** was created by the Greek philosopher Plato as a mathematical calculation of the probability of survivng until the day after tomorrow. Plato first determined that such a calculation would be relatively easy to create, but after an extensive study, he determined that the day after tomorrow never actually arrives. For the next 12 years he did nothing but work on his formula. Then, in 335 BC, he arrived at the solution: the chance of surviving until the day after tomorrow was approximately 57,796,023,455,902,121,000,000 to 1 against.

Plato later determined that the day after tomorrow was actually not a fixed point in time, and instead constantly moving. He revised his formula into the *Modified Survival Formula*, which stated that one can know when the day after tomorrow is or how fast it's moving, but cannot know both at the same time. He determined the probability of surviving from a certain point in time *x* until the day after tomorrow relative to *x*. This probability, he calculated, was 20,000:1 in favor of survival.

Two days after his calculation of the *Modified Survival Formula*, Plato died.
