A child asks: “Why is the sky blue?” What are you supposed to say? You don’t know the answer. The technical answer is Rayleigh scattering, but that seems like the sort of thing you learn about in a graduate class on electromagnetism. I hope to give you an answer that you could explain to a child.

Book Review of WEATHER, MACROWEATHER, AND THE CLIMATE by Shaun Lovejoy (2019)
Weather, Macroweather, and the Climate is an excellent book on climate science. Lovejoy engages both climate scientists and climate skeptics and attempts to persuade both. It tries to be accessible to a general audience, but I think it ends up being accessible to almost any scientist or engineer. This book is more about climate than about climate change. Lovejoy does not mention climate change until the 6th chapter, out of 7 chapters total. Instead, his main goal is for you to understand the patterns of motion in the atmosphere.
Entropy
Entropy is a weird thing. It is used in multiple seemingly unrelated contexts. None of them have intuitive definitions. I hope to simply explain what entropy is in these contexts and why they all deserve to have the same word.
Fractal Dimensions
You probably know fractals as cool-looking mathy shapes. Maybe you’ve also heard that fractals can have non-integer dimensions. This is extremely weird. I hope to give you an idea of what fractals are and help you to understand why we say that fractals’ dimensions can be non-integer.
