Okay, I've pushed my book up to roughly the year 1996. Getting closer to the present. Considering I started in the 1800s, that's progress.
Also added two Star Trek quotes.
I guess I'll take a break for the evening.
Waiting on some email interview requests from some of the actual invisibility scientists, so tomorrow I'll write the chapter after that one, where I discuss all the weird crap that people have developed since the first cloaking ideas.

Okay, let's to an #OpticsLessonOfTheDay: why is the sky blue? The answer is an interesting mix of several different aspect of physics as well as the working of the human eye.
First off: we note that the sun radiates light somewhat uniformly over the entire visible spectrum of light, which ranges from 380 to 750 nanometers. (Image via Wikipedia.) It peaks a bit in the middle of the spectrum, so we picture the sun as a bit more yellow than white.
Now, during the day, we see blue light everywhere *except* in the direction of the sun. This is because the gases in the atmosphere preferentially scatter blue light. All the blue you see is from light scattering off of atmospheric molecules.

Reminds me of a guy I heard of who got the vaccine and the very next day was arrested for having sex with an alpaca these side effects are out of control I tell you
Also, a “true” story: in The Discoverie of Witchcraft, published by Reginald Scot in 1584, he recounts the story of a bishop caught having sex with a nun. The bishop later argued that it was an incubus disguised as him.
Scot was having none of that nonsense.

Now that I *have* taken an ambien, this may be the perfect time to finish my bumble account, especially considering my self-destructive nature
Yep, a perfect time to work on a profile. Image
So far the experience has convinced me that I am definitely spending the rest of my life alone and sad.

That’s it - the name “Greg” is too hard to hear through a mask at the coffee shop. Going to switch to my old standby “Beavis.”
In grad school, I used to put that in as my name when out to dinner with friends. My friends HATED me because as soon as they called out “Beavis,” the whole restaurant would turn and stare.
I mean, who says you have to use your *own* name for an order?

So I go to a movie and come out seeing that all sorts of people are explaining the phenomenon wrong. To me. An optical physicist.
So let's have a quick #OpticsLessonOfTheDay: there are a bunch of different ways that you can get rainbows, and they're all different!
The most familiar rainbow effect is the one that Isaac Newton studied using a prism, and also forms the cover of Pink Floyd's Dark Side of the Moon: Image
