Cryonics Calculator

cryonicscalculator.com is an online calculator in which the user inputs her opinion of the odds of critical events happening, and the calculated odds of cryonics success are output. The output is both an overall % chance of success and a graph showing how events unfold over time.

User inputs are:
 * user age.
 * user age when deanimate (are declared dead).
 * odds that life extension therapies will eliminate death due to aging, before deanimation.
 * odds that an immediate disaster happens, like autopsy, deanimation in a remote location, etc.

And for each of the marching 20-year periods, input the odds that the following will happen:
 * a natural disaster (fire, flood, etc) at the cryonics facility.
 * storage failure (dewar leak, sabotage, etc).
 * financial failure of cryonics company.
 * regulatory interference (coroner exhumes, cryonics outlawed, etc).
 * other miscellaneous disasters of the user's choice.

And then the last input:
 * years from now that the user thinks there is 50/50 chance that affordable reanimation technology will become available.

The probability equations derivations were originally completed by Brook Norton on 11/27/93. An introduction to the method was published in the Alcor magazine shortly thereafter. The calculator was hosted on a web site in 2010 and has maintained an online presence since then. On 4/24/20 an independent review of the derivations was completed by an independent mathematics graduate student. Details of the derivations are available at the calculator web site.
