If this hypothesis is correct, that would mean that when you’re sieving up to 1 trillion, you can cross off multiples of 2, then 3, then 5, and keep going until the inclusion/exclusion sum starts to involve divisors over about 1 million — beyond that point, you can’t calculate the terms in your sum. In… Continue reading A New Generation of Mathematicians Pushes Prime Number Barriers

Bats Use the Same Brain Cells to Map Physical and Social Worlds
A fruit bat hanging in the corner of a cave stirs; it is ready to move. It scans the space to look for a free perch and then takes flight, adjusting its membranous wings to angle an approach to a spot next to one of its fuzzy fellows. As it does so, neurological data lifted… Continue reading Bats Use the Same Brain Cells to Map Physical and Social Worlds
The Hidden Connection That Changed Number Theory
There are three kinds of prime numbers. The first is a solitary outlier: 2, the only even prime. After that, half the primes leave a remainder of 1 when divided by 4. The other half leave a remainder of 3. (5 and 13 fall in the first camp, 7 and 11 in the second.) There… Continue reading The Hidden Connection That Changed Number Theory

The AI Boom Could Use a Shocking Amount of Electricity
Every online interaction relies on a scaffolding of information stored in remote servers—and those machines, stacked together in data centers worldwide, require a lot of energy. Around the globe, data centers currently account for about 1 to 1.5 percent of global electricity use, according to the International Energy Agency. And the world’s still-exploding boom in… Continue reading The AI Boom Could Use a Shocking Amount of Electricity
