A City on Mars★★★★★
Kelly and Zach Weinersmith Accessible and intricately researched, with scattered humor to keep the reader’s interest. Getting to space is the easy part. Staying there is going to be a lot more complicated.
The End of Everything (Astrophysically Speaking)★★★★★
Katie Mack An engaging read for the general audience about what we currently know about the history and structure of the universe and what that knowledge – and the pieces we don’t know – might mean for its future and eventual end.
Four Lost Cities★★★★★
Annalee Newitz Fascinating look at how cities form, live and die, seen through archaeological discoveries at Pompeii, Angkor, Cahokia and Çatalhöyük.
iNaturalist★★★★★A citizen science project for reporting and identifying wildlife observations, plus a phone app for use ‘in the field.’ Think of it as Pokémon Go for real animals and plants.
Soonish★★★★★
Kelly and Zach Weinersmith Fascinating, accessible, funny, and still relevant overview of cutting-edge tech, even though it took me 7 years to get around to reading it.
Under Alien Skies★★★★★
Philip Plait A fun look at what it would be like to visit other planets or star systems, weaving together sci-fi scenarios, the science behind them, and the history of how those discoveries were made.
