Getting your first telescope should feel exciting, not frustrating. If I avoid a few common beginner mistakes, I can turn that confusing bundle of glass and metal into a tool that reliably shows the ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

A quality laser printer delivers unparalleled speed, pristine text, and reliable paper handling. Find the right option for your home or office from our list of tested picks. Most of my current work ...

When the first laser and inkjet printers for PCs arrived in the mid-1980s, they could only print in monochrome, and their respective advantages were obvious. Today, the differences between laser and ...

Considering a laser hair removal service? I get it, and I've actually tried them. My review? They're painful, expensive, and take a lot of sessions to see results. Soon, I'm running right back to ...

William Truswell, MD, FACS, operates his own cosmetic and reconstructive facial surgery practice. Dr. Truswell was the first in his area in Western Massachusetts to have an accredited private office ...

Laser-produced plasmas are plasmas produced by firing high-intensity beams of light. Laser-produced plasmas have been used to create short bursts of x-rays and to accelerate particles — so-called ...

Abstract: The transverse impedance of the LHC collimators will likely dominate the overall transverse impedance in the LHC at high energies and potentially limit the maximum intensity. A prototype ...

Abstract: X-ray and gamma-ray imaging is essential in nuclear medicine. Recently, various therapeutic radionuclides have been proposed, increasing the need to visualize their pharmacokinetics. In ...
