Earthbag Building

By Kaki Hunter and Donald Kiffmeyer.

Every now and then I run into a book that I dream will teach me a new survival skill should everything go to shit, and I need to start over. This time it's earthbag building... If I lost my job and home, I could always build a new home with bags of earth.

Reading this book gave me anxiety. It would take so much work to build a new home from earthbags. I don't have that patience.

Reality is not what it seems

by Carlo Rovelli

I love Rovelli's writing. He is very good at describing, at taking you step by step though the thought process needed to understand Quantum Gravity. Or maybe he seduces you into believing that you understand. 

Back in November, I decided to get up to date with what's current in theoretical physics. At this point I've taught myself a few things, but mostly I've decided that understanding theoretical physics would be a difficult full time job. I'm going to pause this effort for a while.

Roger Penrose...

The Road to Reality-- A Complete Guide To The  Laws Of The Universe, and...

Fashion, Faith and Fantasy in the New Physics of The Universe.

Every now and then I like to attempt to can catchup on the state of physics. With Penrose winning a Nobel in Physics, I thought I'd go through some of his books.

These books are very dense. Not light reading.

The Road To Reality is a great reference. If I wanted to know the math behind something, say String Theory or Quantum Gravity, I could look it up in in this book. Then, when I didn't understand part of that explanation, the book would offer me pointers to the math and science that I needed. And so on, all the way back to the roots of science and mathematics.

Fashion, Faith and Fantasy is different in that it tells more of the narrative of various problems in physics, who is investigating them, why they are important, and the directions the solutions are headed in.
