Bill Gates—he of the $79 billion net worth, per Forbes—released his annual summer reading list on Tuesday. In between running one of the world’s largest charities and serving as technological advisor to the company he co-founded, Microsoft (MSFT), Gates has made a habit in recent years of letting the world know what he’s reading.

Gates unveiled his new 7-book summer reading list in a post titled “Beach Reading (and more)” on his personal blog, Gates Notes. Included in this year’s list is The Magic of Reality, by Oxford University evolutionary biologist Richard Dawkins. There’s also On Immunity, by Eula Biss, which fits in well with one of the goals of the Bill & Melinda Gates Foundation by tackling the issue of childhood vaccinations.

The billionaire techie also noted that he’s trying to lighten the mood a little bit this year. “This year I tried to pick a few more things that are on the lighter side. Each of these books made me think or laugh or, in some cases, do both,” Gates wrote in the blog post.

In that vein, Gates includes a book adapted from Allie Brosh’s popular comic blog, Hyperbole and a Half, which Gates calls “funny and smart as hell.” Another item with a more graphic option is Randall Munroe’s XKCD, which draws from Munroe’s webcomic of the same name, which features a lot of mathematical and scientific humor. “It’s that kind of humor, which not everybody loves, but I do,” Gates writes.

The rest of the books Gates recommends reading this summer are: What If?, also by Munroe; How to Lie With Statistics, by Darrell Huff; and, Should We Eat Meat?, by Vaclav Smil.
