I’m currently reading a popular science book called
We Have No Idea, A Guide to the Unknown Universe”, by Jorge Cham and Daniel Whiteson.
The title is a mantra that’s repeated over and over in the text.
It’s basically a survey of contemporary understanding of physics, with an emphasis of things we don’t know. Some of them are “why” questions, like “Why is inertial mass exactly equivalent to gravitational mass? Ans: We have no idea.” Although “why” questions are often considered outside the realm of legitimate science, in this case the authors conclude that the answer to that question would be a definite positive step towards understanding how the universe is put together.
Other questions are “what” questions, like “What is ‘dark matter’?” and “What is ‘dark energy’?” Although they comprise 95% of the observable universe, and “ordinary” matter, with which we are familiar, only 5%, “we have no idea.”
The style of the book is a bit like a “Dummys” series book, with lots of cartoon drawings and awful puns, but I’ve gotten past that now and am enjoying it.
Jorge Cham has a PhD in robotics (Stanford). I’m guessing it’s he who contributes the cartoons.
Daniel Whiteson is a professor of experimental particle physics at UC Irvine, and works with the large hadron collider at CERN.
Here is a video (over an hour!) of them talking about their book:
