That's a cool coincidence, the universe wants you to learn about them :p

Thanks for that advice also, it's something I don't take into consideration much that people use night mode. I had a look and yeah the equation is not visible, that's something I'll remember to consider in the future. It was weird that it didn't have the white back ground though.....

I'm glad you enjoyed the post, I'l get around to part 2 in the next few days, i'm thinking of focusing a bit more on the physics, we'll see how it goes :p
