Gravity is a force we experience every day, yet it challenges our basic understanding of how the universe works. Why does ...

The object’s weight is referred to as the measure (usually in pounds) of the force of gravity on the object. Basic physics teaches us that the larger the mass (weight) the greater the attractive ...

In the 1960s, physicists developed a mathematical formula that, in principle, describes the effects of Casimir forces on any number of tiny objects, with any shape. But in the vast majority of ...

Optical manipulation (OM), such as optical cooling 1, trapping 2, binding 3, 4, 5, sorting and transporting 6, 7 by utilizing optical forces, has experienced intensive development in the past 40 ...

Discovered in 1948, Casimir forces are complicated quantum forces that affect only objects that are very, very close together. They're so subtle that for most of the 60-odd years since their ...
