Metro21 Lunch and Learn
We hope to see you on Friday, February 15 at 12:00 pm – 1:00 pm in 1002 Hamburg Hall at CMU for a Metro21 Lunch and Learn!
This Lunch & Learn will highlight Diane Turnshek, Special Lecturer in the Physics Department at CMU, and her seminar titled “Light Smart: Dark-Sky Friendly Artificial Lighting”.
Diane will discuss how billions of dollars a year are wasted on artificial lighting and the negative effects the light pollution has on plant, animal and human populations. But there’s good news: the City of Pittsburgh is refitting 40K streetlights over the next two years -- replacing high pressure sodium vapor bulbs with much more efficient, 2700K or less, shielded, dimmable LEDs. To aid in future research and decision making, we will be flying drones over Pittsburgh on moonless, clear nights to make the first, publicly available, high resolution light pollution map of a city.
