From Jenna Orkin Trump 2.0: Who would be in the running for top jobs in Trump's second administration? The Americans Prepping for a Second Civil War Voting technology is more secure than it’s ever been. This is the result of a shift in American voting procedures more than two decades in the making: Most people now vote by machines that efficiently scan paper ballots. Or they use touch screens and other forms of direct-recording electronic machines (“DREs”), which also generate backup paper records. Those physical paper trails are an election safeguard—ballots are verifiable, auditable and recountable, as I wrote on Saturday. In October, amateur mathematician Luke Durant discovered a new prime number, and it’s 41 million digits long. Yup, the number has 41,024,230 digits (for comparison, the approximate number of total atoms in the observable universe is only about 80 digits long). A prime number is a number that can be divided only by itself and 1; so 3, 7, 13, 17, and 19 are all primes, whereas 15 is not. How he did it: Prime number hunters use a computing trick devised by 17th-century French mathematician Marin Mersenne, who discovered that multiplying 2 by itself some number of times (2^n) and then subtracting 1, you sometimes get a prime number. Durant assembled a global supercomputer across 17 countries by buying processing time from various cloud GPU providers to crunch through larger and larger iterations of the Mersenne calculation, churning through about 12 times as many numbers as every other computer involved in the Mersenne prime search combined.
