Almost anyone can learn about the special theory of relativity from these lectures. I actually can't believe that I studied from a professor who teaches in the USA and in so simple way. I am grateful.

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.

this course gave me more curiosity about einsten, (even though I haven't completed it yet :)) if you are interested in einstein and his theory, I suggest you take a look

Can't believe this course is taught to Stanford students (or any college students). The lecturer is soooo repetitive. He tells you what he's going to tell you, then he tells you and then he recaps. And he summarizes it all at the start of the next lecture. And there's a separate summary lecture at the end of each week. That said, he explains the material well. Cut the lectures by 2/3 and you'll have a 5-star course.

The course was too simple and the derivations too slow. I expected more involved math and harder quizzes.

This fascinating course presented by a historian of science covers not just the basics of special relativity but the historical context as well. The lecturer starts off each week with some Einstein quotes and goes to great depths to explain the basic concepts at a level that is accessible to students with minimal experience of maths and physics. The concepts are firmly drilled in with plenty of optional quizzes after each mini-topic, and a summary video at the end of each week. The lectures are long but anyone short on time has the option to go straight to the weekly summary/quiz, and/or play videos at up to 2x speed (especially in weeks 2 and 3).
The main highlight for me was the explanation of the famous Twins Paradox and other related paradoxes which are resolved by understanding frames of reference and the relativity of simultaneity. Another bonus was an explanation of the bending of light by gravity through a simple thought experiment involving an accelerated elevator.
Some important topics not covered in the course, or only hinted at, are: treatment of accelerated reference frames (required to derive the relativistic rocket equations), relativistic momentum and kinetic energy (required to calculate the rocket fuel required) and relativistic energy (used to derive Einstein's mass-energy equivalence formula).
Overall I highly recommend the course to anyone with the time and inclination.

So you're wondering if you have the ability to learn about the Special Theory of Relativity. After all, this theory was developed by a genius and it involves math, something that many people shy away from. Doesn't it take a background in physics and confidence in your math ability to get something out of the class? No. The remarkable thing about this class is that is presented at multiple levels simultaneously. If you are confident in your knowledge of physics and math, the explanations and optional exercises will be a welcome challenge. At the same time, the general concepts are explained in such a manner that you'll learn enough about the Special Theory of Relativity to get the "big picture" even if you don't immerse yourself in the mathematics. From there you can learn about it in more detail, if you wish. The test for me in taking any class is whether I'm able to explain the concepts to someone else in casual conversation. This course certainly met the test.

This course was exactly what I was looking for to get a good understanding of the Special Theory of Relativity for a non-specialist. The course progression was very good, building new concepts on top of the previous ones. The video lectures were lively and well presented. The difficulty level and the required math skills were exactly what the course description indicated.
I recommend future students to take this course at a steady pace, and to allocate enough time to take notes, to review the concepts and to go back if necessary. Don’t rush through it. It is very useful to try to solve the optional problem sets. The main difficulty is not related with the math, but with the relationship between the equations and the physical phenomena they describe.
I am 100% satisfied with this course. As a matter of fact, I plan to go again through my notes to make my own personal recap of the main concepts and formulas.
Thanks a lot to Professor Lagerstrom!

Very professional approach by Professsor Larry Lagerstrom. His patience in teaching is highly commendable. The key feature of the course is "Make Haste Slowly" This ensures that no matter what background of academics you come from, at the end of the course you will have understood the principle aspects of Special Relativity. The syllabus is designed very well. Both qualitative and quantitative elements are covered nicely. A participant will understand all the key concepts of special relativity like time dilation, length contraction, relativity of simultaneity etc He will also understand the most famous paradox of special The Twin Paradox and get some insight into the most famous equation E=mc2. I salute Prof Lagerstrom for his extreme patience in teaching a complex topic. I recommend this course to anyone who wants to know a bit about how the Universe works even for those without any background knowledge of Physics or Mathematics.
