== The Biggest Ideas in the Universe == == Space, Time, and Motion == === 2022 Sean M. Carroll 540.11 CAR Beaverton Library === This purports to be introductory material for the layman, but dives into the algebra and the ''implied'' differential equations pretty quickly. If I had lots of spare time, I'm sure I would get something out of it (I know most of the math already), but it is in demand, so back to the library it goes. A lay reader will need '''''LOTS''''' of spare time.
