Scientists at Penn State have discovered an effective and precise way to make ultraminiature metal wires in very close proximity to each other. Their work—important because nanoscale construction ...

Just as a meter stick with hundreds of tick marks can be used to measure distances with great precision, a device known as a laser frequency comb, with its hundreds of evenly spaced, sharply defined ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

Hozo Design has a pair of digital measuring devices in the NeoRuler and M-Cube, with both having the goal of making both micro and macro measurements more precise and easier to accomplish.
