What’s really behind baseball’s home run surge?

Some pitchers are convinced the balls are being messed with behind the scenes.| Short Read

At the 2019 Major League Baseball All-Star Game, Houston Astros pitcher Justin Verlander griped that too many home runs had been hit so far this season. He accused the league of altering, or “juicing,” the balls, making it easier to hit home runs.

Among players and fans, Verlander’s “juicing” claim has gained momentum.

There’s no question that there’s been a home run surge. Home runs per plate appearance is currently sitting at 3.5%, an all-time high. At this rate, players will hit more than 6,600 homers by season’s end, shattering the prior record, set in 2017, by more than 500 home runs.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
