A Fleet of Computers Helps Settle a 90-Year-Old Math Problem

Keller’s conjecture, posed 90 years ago by Ott-Heinrich Keller, is a problem about covering spaces with identical tiles.Over the years, mathematicians have chipped away at the conjecture, proving it true for some dimensions and false for others.It’s easy to see that Keller’s conjecture is true in two-dimensional space.

It was a celebration of how exponential upgrades from the chip industry have propelled progress in technology and society over the past 50 years—and an argument that the party’s not over.“It's going to keep going,” said Jim Keller, a semiconductor rock star who joined Intel last year as senior vice president of silicon engineering, and a cohost of the event.

“I think Juul is breathing a big sigh of relief,” says Marc Scheineson, a former FDA associate commissioner and partner at the law firm Alston & Bird.Gottlieb said the agency still must finalize its policies, which did not specify how convenience stores or other retail outlets could develop a section that makes products “not visible or accessible to persons under the age of 18.” Vape shops that limit entrance to buyers 18 and older won’t be affected, he added.The FDA’s approach is a creative way to address e-cigarettes while avoiding some legal pitfalls, according to Azim Chowdhury, a partner with Keller and Heckman who leads the firm’s tobacco and e-vapor practice.
