It's all written by Yosef Sebag who learns full-time in kollel in Yerushalayim and also holds degrees in physics and electrical engineering.
I learned a lot of fascinating aspects of light that I never knew. Yosef Sebag also includes helpful graphs and images to make things clearer for the non-science reader.
This article can really boost your kavanah and awareness when making the Yotzer Ohr bracha preceding Kriyat Shema in Shacharit.
It also adds proof to the fact that only God could have created our Earth and all the life therein (rather than an unrealistically chancey big bang in a multiverse). Just as one example, Yosef Sebag emphasizes that only band of light useful for life is the one emitted by our Sun.
What are the chances of that, big bangers?
Anyway, the whole article is full of such tasty tidbits that make you want to cheer, "Mah rabu ma'asecha, Hashem - How great are your deeds, God!"

Personally, I'm indebted to his translations of both Chovot Halevavot (Duties of the Heart) and its accompanying commentaries for greater insight into this fundamental mussar classic.
