Make a truth teller for light. Turn an old CD into a spectroscope to analyze light—you may be surprised by what you see. Try pointing your CD spectroscope at the fluorescent light in your room, sunlit ...

A cost competitive circuit of a fluorescent lamp electronic starter that can provide a single-pulse ignition, adaptive preheating time, fast reset and lower voltage working ability is proposed in this ...

A new blue fluorescent molecule set new top emission efficiencies in both solid and liquid states, according to a University ...

To meet rising quality inspection demands in industrial automation, this study presents an enhanced YOLOv5 model for detecting minor surface defects in industrial parts through fluorescent magnetic ...

UV light is reflected off water, sand, snow and concrete. Wear sunscreen even in winter and during cloudy weather. Damaging UV light from the sun still occurs; it is just not as strong as on a sunny ...

Nearly 400 years ago, Galileo looked at the Pleiades star cluster through his telescope and noticed that the seven or so ...
