|Albert Einstein’s theories of
special and general relativity are the most profound revolution in
science in over 200 years. Einstein’s theories forever changed our
concepts of space, time, atoms, light, gravity, mass, motion, and the
universe itself. For physicists, that’s about all there is.
Sir Isaac Newton
published Philosophiae Naturalis Principia Mathematica in 1687,
establishing physics as a rigorous, rational, achievement of human
intellect. Newton’s laws of motion and gravity are comprehensive and
mathematically perfect. They explained every physical phenomenon that
anyone had ever observed, and provided numerical predictions that were
more precise than anyone could measure. Newton’s theories were the
greatest advance in science in at least 2000 years, if not the greatest
more complex than Newton imagined. By the beginning of the 20th
Century, several puzzles eluded solution.
published his theory of special relativity, supplanting Newton’s law of
motion, and refuting his concepts of space, time, and simultaneity.
This forever changed our concepts of reality.
|In 1915, Einstein published
his theory of general relativity, supplanting Newton’s law of gravity.
Einstein opened our eyes to our wondrous universe as it truly is.
General relativity again shattered our concepts of reality, and
revealed the secrets of black holes, gravitational waves, and the
expansion of the cosmos.
goal is to reach as many eager readers as possible, and bring
Einstein’s genius to a wider audience. For those who were reluctant to
face that challenge, this book is for you. I make Einstein’s theories
easier to understand, without watering down his brilliant insights.
As an aid to
students, I provide every step in every derivation of
every prediction of Einstein’s theories of both special and general
Physics is one of
the greatest adventures of the human mind, but with
adventure comes challenge. While I strive to make this adventure as
easy as possible, special and general relativity will be two of the
greatest intellectually challenges of your entire life. Give it your
very best, and you will be rewarded.
