density

This produced a material capable of both high energy density and high power density, a combination that is rarely achieved in a single device.

If the chain eventually matches the store density it already has in the Washington, D.C., area, Zackfia estimates it could support something closer to 2,000 locations nationwide.

To visualize this density, imagine placing the solar system inside a cube one light-year on each side.

The centre of the City of Light has the highest density of silver screens in the world per capita and arguably one of the most cinephile local populations.

That density is emblematic of Hong Kong itself, one of the most crowded cities in the world.
