2. There’s also [this post](https://www.linkedin.com/posts/nobelprize_internationaldayoflight-activity-6931834878007091201-HMe2) in honour of The International Day of Light about the invention, how it works, and what the impact was.

   If you’re on LinkedIn, I highly recommended the Nobel Prize page, it has very interesting posts.
