Where is the Apple Park headquarters with one of the most precise gravity-calibration labs nearby?

Apple Park is in Cupertino, California, at the heart of Silicon Valley. While it is not a physics laboratory, the surrounding region is home to advanced semiconductor and metrology facilities where precision force measurements matter. Silicon Valley’s technology industry relies on understanding electrical and mechanical forces at tiny scales. The area is a major center for applied physics even when the work is not in a university laboratory.
