Let's take a break!
The study of light has led to promising energy sources, lifesaving medical care, high-speed internet, and so many discoveries that we can't name them all at once.
Our friends over at @idlofficial.bsky.social have a lot to share from events happening all over the world.

“We should have a celebration on the International Day of Light.”
“We should involve the Optica Student Chapters.”
“We can ask them to post photos from their events.”
“And Optica can do a 24-hour, round-the-clock social media campaign sharing these photos from chapters.”
This is the result. 🧵
