Planck's constant is one of the fundamental constants that sets up all the "rules" for how things work in our universe. (It’s named after the theoretical physicist Max Planck, who is best known for ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

The introduction of several new dielectric materials for high-speed ultra-large-scale integration (ULSI) microelectronics has increased the necessity for metrology tools to measure the ...
