University education is highly valued in industrialized countries; it is both prestigious and expensive. Under current economic conditions people are finding more difficulty in paying for post-secondary education. Even if you manage to pay for tuition, college textbook prices are often unmanageably high. For those of us who want to acquire college level knowledge but cannot afford it, there are free textbooks available whose authors think education should be more affordable and less exclusive.
Today I present “Simple Nature”, a physics textbook by Benjamin Crowell. Dr. Crowell teaches physics at Fullerton College in California. This textbook can be downloaded as a PDF file so it is very accessible. It is intended as “an introduction to physics for engineering and physical science students.” The topics covered include: conservation laws, thermodynamics, waves, relativity, electromagnetism, circuits, optics, and quantum mechanics. Readers should already be familiar with calculus before reading this book. Enjoy.
