He delved into the literature, coming across a 1974 paper by Carl Pomerance, a mathematician now at Dartmouth College, which proved that any OPN must have at least seven distinct prime factors.“Seeing that progress could be made on this problem gave me hope, in my naiveté, that maybe I could do something,” Nielsen said.

He proved that any set of axioms you could posit as a possible foundation for math will inevitably be incomplete; there will always be true facts about numbers that cannot be proved by those axioms.

Now five seasons old , Formula E is meant to utilize racing —long a rolling laboratory for automotive development, yielding advancements like antilock brakes, traction control, and dual-clutch transmissions—to help EV manufacturers and suppliers like BMW, Nissan, Audi, Panasonic, Mahindra, and Jaguar move their battery-powered products forward .
