In this course we will seek to “understand Einstein,” especially focusing on the special theory of relativity that Albert Einstein, as a twenty-six year old patent clerk, introduced in his “miracle year” of 1905. Our goal will be to go behind the myth-making and beyond the popularized presentations of relativity in order to gain a deeper understanding of both Einstein the person and the concepts, predictions, and strange paradoxes of his theory. Some of the questions we will address include: How did Einstein come up with his ideas? What was the nature of his genius? What is the meaning of relativity? What’s “special” about the special theory of relativity? Why did the theory initially seem to be dead on arrival? What does it mean to say that time is the “fourth dimension”? Can time actually run more slowly for one person than another, and the size of things change depending on their velocity? Is time travel possible, and if so, how? Why can’t things travel faster than the speed of light? Is it possible to travel to the center of the galaxy and return in one lifetime? Is there any evidence that definitively confirms the theory, or is it mainly speculation? Why didn’t Einstein win the Nobel Prize for the theory of relativity? About the instructor: Dr. Larry Lagerstrom is the Director of Academic Programs at Stanford University’s Center for Professional Development, which offers graduate certificates in subjects such as artificial intelligence, cyber security, data mining, nanotechnology, innovation, and management science. He holds degrees in physics, mathematics, and the history of science, has published a book and a TED Ed video on "Young Einstein: From the Doxerl Affair to the Miracle Year," and has had over 30,000 students worldwide enroll in his online course on the special theory of relativity (this course!)....

This course is very comprehensive and well prepared material for understanding the Special Theory of Relativity. Larry (the instructor) is very expert and has broad knowledge in explaining the course.

I enjoyed this course very much. Professor Larry Randles Lagerstrom made a difficult subject easy to understand. Especially for a fellow who at 85 has forgotten a lot of what he learned in college.

Professor Lagerstrom went out of his way to include a wide range of understandings in this ride to understanding relativity and its' non-symmetric duality. (I always thought relativity was the same for the one in motion as the one at rest... not true! Time dilation happens differently.) This and many other wonderful revelations were opened for me without the need to perform the math, altho... I made myself go back and do a sheet of Algebra "brush up" and then re-attacked the course by working all the math, so I really had two tangents of learning here. If I was ever trapped in a Spaceship and had to be on time for dinner on Earth, I'd trust Larry to tell me how fast to go, implicitly. My new understanding of "frames of reference", relative length, leading clocks, time dilation and temporal plotting has all but destroyed the science behind all of my favorite television shows... but I can calculate the Lorentz factor and truly can mentally conceptualize the effects of near light movement and it has made me believe that black holes exist as a continual part of the Big Bang, as time restarts when you reach the center (and nearly stops on the way). I also couldn't understand how a photon could last all the way to Earth, until I learned of the muon! I couldn't picture this in my mind, until I took this course. Thank You!

I enjoyed this course tremendously and recommend it to anyone who wants to delve into the Special Theory of Relativity. It's easy to see why Larry Randles Lagerstrom has received awards for excellence in teaching. He knows where students are likely to get confused and gives careful explanations along with helpful reminders, so students can move along with the material without having to go back and re-read earlier sections.

This was an extremely interesting course. Thank you for offering it. You really made it understandable while still maintaining the wonder of such "weird" phenomenon.

Exceptionally good course.

This is the first course I paid for verified certificate and finished in 3 weeks instead of 6. It was almost like detective novel. I could not wait to see what happens next.

Dr Lagerstrom took his time explaining everything slowly.

I wish he will do a course on general theory of relativity too.

Sometimes a little too thorough on the explanations, but overall an excellent course.

This is hands down the best introduction to the Special Theory of Relativity I have ever found. The instructor really explains everything so lucidly that even lay audiences without a strong math or physics background can grasp the theory. I would really love to see a course by this instructor on the General Theory of Relativity as well!
