    The word "physics" is only about 160 years old! Before then, the activity was called "natural philosophy." I believe that every philosopher nowadays should know some basic physics and astrophysics.



    When physicists write for each other, they use a lot of mathematical artillery. But when I have struggled with the details, and discovered that a lot of the math is the sort of algebraic manipulation and power notation we are all supposed to have learned in 9th grade! Another fair slice of the physics requires no more than freshman calculus / linear algebra / vector spaces. Or sine, cosine, and the beautiful number e. Sometimes, what a physicist is saying is that theory gives us an equation about how a quantity changes over time. That's called a "law of motion." Common sense tells us what the value of that quantity is at some point in time; that's a "boundary condition." Given a law of motion and a boundary condition, we can recover an equation giving the value of the quantity at every point in time; that's called "solving a differential equation to recover the equation of state." We don't need to understand the mathematical tricks needed to obtain this solution. Besides, the solution can often be obtained using computer software.



    Universities should offer a few physics and math courses for non-majors that flesh out what I say above.

    Some of these books are not easy reading for me either.



    In 1900, there was no conclusive evidence that matter is made of atoms. There was no understanding that atoms have parts, and that chemical properties derive from the internal structure of atoms.



    The 20th century is the time when we humans sussed what matter is made of (electrons, up and down quarks, neutrinos), and what forces govern matter (gravity, electromagnetism, strong weak nuclear forces). Gravity and electricity were known before 1900, but the 20th century made huge additions (i.e, relativity, QED) to our understanding of both. The road to the quantum nature of reality began with a paper published in 1900.



    This huge rise in our understanding of nature is probably the greatest achievement of the 20th century. Few people who are not professional physicists and chemists seem aware of this. My reading list proves that professional physicists have been quite willing to share the story of their adventures with the wider educated public.

    Wow what a long list. It is hard to find a book about physics that not over my head. I happen to have known many scientists and its easy for me to get lost in the complexities of their science. I love the philosophy of physics its fascinating ... the math ... forget it.



    Thanks for providing the possibility of physics reading for the lay person, like myself. Your story is now saved in my library for future reference.
