Fresnel – A life full of achievements

The year of 2015, chosen to stage the UNESCO International Year of Light 2015, coincided with many anniversaries regarding history of the science of light and one of these was Fresnel’s Wave Theory of Light. Quite frankly there could be an anniversary for Fresnel each year for the next six years to celebrate one of his many achievements, each one equal to the magnitude of and stems from his wave theory.

Laser Fun Day

The Student Optics Chapter, or SOCk, at the College of Optical Sciences at the University of Arizona put on its fifth annual Laser Fun Day this year in conjunction with the International Year of Light and Light-based Technologies (IYL 2015). This is our largest outreach event every year, and we had a record attendance this time, between 1200 and 1400 people. We invited the entire Tucson community by sending out hundreds of flyers to the schools and other educational organizations.

Night is Canvas

At the Light Painting World Alliance website, you’ll find the phrase “Night is Canvas”. Night is no ordinary word for me, I suffer from night blindness. It’s a powerful,  often frightening word, separating me from the able bodied, putting me in the folder labelled “Unable”- legally blind, asking for help to cross the street. Night, and its draining, light-less hardships, needn’t be only that. After all, the other part, “canvas” is what  matters more in the end.

Skyglow: measuring light pollution in the UK

Skyglow is the halo-like artificial illumination of the night sky above towns and cities. It’s also the name of a major new study into light pollution in the UK by Hillarys. Using satellite images taken between 1992 and 2014, Skyglow shows how the UK’s night-time skies have changed. The research charts a 28% decrease in light pollution*, with falls in every region – and projects this data into the future. You can see the interactive satellite imagery and full study on the Skyglow project page. Or keep reading to find out the story behind the story.
