## newton

The unit of force required to accelerate a mass of 1 kg by 1 m per second per second. 1 N is equal to 100 000 dynes. (Sir Isaac Newton, 1642–1727, English mathematician, alchemist and physicist).

Newton disk - a disk on which there are seven colored sectors, which, when rapidly rotated, appear white.
Newton law - the attractive force between any two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Synonym(s): law of gravitation

The scanning probe microscopes invented in the 1980s are electromechanical devices, which require precision actuation with Angstrom resolution, microfabrication of cantilever probes, force sensing with resolution measured in piconewtons, and a fundamental understanding of dynamics and control to increase imaging speed and spatial resolution.
The PicoForce Control System provides accurate manipulation and measurement of forces at the picoNewton level, including inter- and intramolecular forces for applications from drug discovery to basic molecular-scale research.
But when shone through a microscope, the tiny, piconewton forces that an intense laser beam can exert prove ideal for manipulating objects in cellular space.
Zhu and colleagues have used the new technique to show that gene mutations responsible for mental-health diseases change molecular interactions by a few piconewtons. These small changes then have a tremendous ripple effect.
