Creating 3D-printed materials that shrink more precisely

From houses to hearing aids, three-dimensional (3D) printing is revolutionizing how we create complex structures at scale. Zooming down to the micro and nano levels, a process known as two-photon polymerization lithography ...

The origins of the black hole information paradox

While physics tells us that information can neither be created nor destroyed (if information could be created or destroyed, then the entire raison d'etre of physics, that is to predict future events or identify the causes ...

The science of photonics includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. The term photonics thereby emphasizes that photons are neither particles nor waves — they are different in that they have both particle and wave nature. It covers all technical applications of light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. Most applications, however, are in the range of the visible and near infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s.
