VirgilgianniTim O’Brein’s The Things They Carried - about a platoon of American soldiers fighting on the ground in the VietnamI also have some good short sci-fi short stories, The Last Question by Isaac Asimov, Author C. Clarke's Nine Billion Names of God, Karen Joy Fowler's Standing Room Only, Pamela Zoline's Heat Death of the Universe
great taste. some of my favorite SF shorts I read this year
learning to be me - greg egan (an implant in your brain observes your every thought and learns how "be you")
the gentle seduction - marc stiegler (one of the best pieces of "post singularity" fiction ive seen)
it looks like you're trying to take over the world - gwern (the classic ai risk parable)
I also read and really liked the Three Body Problem (first contact made by cultural revolution china) books by cixin liu, and blindsight (first contact with very strange aliens) by peter watts.
for non-fiction im currently reading the vital question (research into the first multicellular life on earth) by nick lane and its really good and accessible (i have nothing after highschool biology)
