Inside the Vera C. Rubin Observatory's Quest To Map The Universe

2 days ago | photonicsonline.com | John Oncea

By John Oncea, Editor The Vera C. Rubin Observatory in Chile will revolutionize astronomy with its massive digital camera, real-time data, and a decade-long sky survey, hunting Planet 9. In 1898, Moritz Behrend and his three sons, Ernst, Otto, and Bernard, formed the Hammermill Paper Company along the shores of Lake Erie, in Erie, PA.
6 Surprising Facts About Wire

2 days ago | rfglobalnet.com | John Oncea

By John Oncea, Editor RF wire tech is rapidly evolving, enabling 5G/6G, defense, and smart monitoring, with miniaturization, durability, and sustainability driving innovation. In my job, not every story can be about neutralizing drone swarms with radio waves, understanding satellite orbits, or NASA acquiring GPS signals from the moon. No, sometimes I have to cover amplifiers and oscillators, power electronics, and interconnects.
How RF Helped Find Richard III Of England – 527 Years After He Was Buried

Photonic Gap Band Materials: Engineering The Flow Of Light

1 week ago | photonicsonline.com | John Oncea

By John Oncea, Editor Photonic gap materials, or photonic crystals, are structures with a periodic dielectric profile that prevent light from propagating at certain wavelengths. This creates a "gap" where light cannot travel, offering potential for optical devices like filters and waveguides. Formed in Tulsa, OK in 1967, the Gap Band was based around the Wilson brothers – Charlie, Ronnie, and Robert.
