“Thank the good God we have all got through and the only family that did not eat human flesh,” wrote fourteen-year-old Virginia Reed, a surviving Donner Party member, in an 1847 letter. “Don’t let this letter dishearten anybody and never take no cutoffs and hurry along as fast as you can.” Reed reported being “pleased with California, particularly with the climate.” 

The first known legal use of the phrase act of God was in a 1581 English case concerning property inheritance. It referred, in that instance, to death, declared by the judge to be among “those things which are inevitable by the act of God, which no industry can avoid, nor policy prevent.”

Bibliophilic bishop Richard de Bury lamented the burning of the Library of Alexandria. “Who would not shudder at such a hapless holocaust, where ink is offered up instead of blood,” he wrote in 1344, “where the devouring flames consumed so many thousands of innocents?”

“Pompeii like any other town,” Herman Melville wrote in his journal during an 1867 visit. “Same old humanity. All the same whether one be dead or alive. Pompeii comfortable sermon. Like Pompeii better than Paris.”

The opening of a particle accelerator at Brookhaven National Laboratory in 2000 inspired fears that high-speed collisions might launch a chain reaction that could turn the earth into a hyperdense sphere about one hundred meters across. A risk calculation determined this to be unlikely; if the collider were to run for ten years, the chance was no greater than 1 in 50 million. “The word unlikely, however many times it is repeated,” wrote concerned scientists, “just isn’t enough to assuage our fears of this total disaster.”
