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?

Thanks for helping me understand the Special Theory of Relativity, covered a lot of ground but repeated it so it really could sink in. Like your style and want to thank you for your assistance. Thanks

This course is engaging and interesting. The lecturer inspires you to learn and open your mind. The course itself can be hard in areas but if you stick with it, eventually you can work it out. There is a fair bit of algebra (which I never studied at school) but I still made it! I recommend this to anyone who wants to understand time and space and be drawn into the fantastic world of Einstein.

After reading almost a lifetime books about the works and accomplishments of Einstein (not being a graduated scientist but huge fan of the topic), it is amazing to follow this this course and explore this world in a whole new sight. Fantastic stuff brought by the best instructor by far. I think I will start all over again. A lot is much more obvious now, or is it? Triple A+ for Larry. Thank you.

I can't stress enough how good this course is. It's the best course i've ever taken in any subject. It's really impressive how much energy, thought, patience, care was put here. I'm deeply thankful for this. You guys made me so happy. Almost everything someone need to know about STR is here. And the teacher... maybe my favourite physics teacher ever. This guy is the golden standard of teaching.

This is an excellent course for everyone who is interested in Einstein's special theory of relativity. All concepts about the theory are presented in a simple and intuitive way, therefore anyone with basic math knowledge will understand it easily.

Also, professor Larry Lagerstrom is a very charismatics person, and his talent for teaching other people made this course an amazing experience.

This is a greate course. Many thanks to all involved in providing such a very well elaborated course, modeling such a complex subject in a "simplified" version that is reachable by many people that would be disencouraged by maths and formulas intrinsic to the subject. Thanks also to Professor LArry by making the course even more entusiastic and attractive by given many examples along it.

The course is very well designed for someone with little or no knowledge of the subject matter. The only quibble I had was with respect to the time spent on the very basics of the maths and what I felt was somewhat repetitive nature of some of the points made, if adjusted for that one could lop off several hours from the course length and might actually encourage more participation.

This is the first course I ever finished on coursera! Thanks to Prof. Lagerstrom for making the course so easy and engaging for people with any level of maths and physics knowledge to follow and pick up. I've really enjoyed the whole journey and gained knowledge about this universe. It's definitely worth recommending to anyone who's interested to know more about the world around us.

Great course. The instructor goes slow and repeats important points for maximum retention. Key equations are rigorously derived (requiring only high school algebra) but are rarely required in the weekly quizzes. After completing this course I have a better understanding of special relativity and (thanks to the final week) better understand its relationship to general relativity.

Fascinating course and a material presented in a super approachable way. Many paradoxes thoroughly explained - for the first time for me everything from start to finish was crystal clear. Amazing how almost all of these interesting phenomena, including Lorentz transformation, can be derived simply by using pythagorean theorem and common sense. Can I have a second helping please!

I have always wanted to understand the basics of the Special Theory of Relativity but when trying to read about it found that I did not have the appropriate post high school background in math and physics to understand the theory. Professor Lagerstrom presented the information in a cogent manner that enabled me to grasp both the theory's underlying principles and its beauty.

Very well done. I learned a lot and I'm very pleased with the results I achieved. I learned to study with purpose and to be patient in my learning. I learned to listen intently and apply what I learned. Even old dogs can learn new tricks. I really enjoyed listening to Mr Lagerstrom's lectures. He is knowledgeable and interesting to listen to. He made the course easy to follow.

This course is outstanding. I have tried other self-learning STofR courses and never got past the preliminary steps. The professor is outstanding, the amount of effort to make Special Relativity concepts understandable at the high school algebra level must have been immense. Thanks for expending the effort.

Es un gran curso, el profesor tiene una gran experiencia haciendo clases y he aprendido mucho tomando el curso, ayuda que esté el texto en ingles de sus diálogos para traducirlo si hay alguna duda. El curso cumplió todas mis expectativas, felicito al equipo que diagramó y preparó este lindo curso para los amantes de la física y la astronomía. Un abrazo a todo el equipo.

This is a wonderful path to embark on for those who wish to have a different perspective on the natural laws. It provides a robust platform for pursing more advanced journeys and enhance their ability to analyse and contemplate. The course material is really good and is definitely recommended for people who wish to step out of their boundaries and grasp more of life.

For foreigners, the subtitles are very useful. Sometimes they are not correct and students could have correct them if there would be some tool to propose corrections as it is sometimes the case for the correction of OCR for old newspaper.

I have learned a lot with this course and would like to thank you for providing this material to all the students in the world.

I must say that it is a great course. It moves along nicely (though at times a bit fast); the context has been laid out well and there is enough of summarizing and 'looking back' before moving forward. This course is an ideal beginning for anyone who wants to deep dive into relativity at a later stage! My thanks to Coursera and special thanks to Prof. Lagerstrom!

As a student hoping to study Physics in University, this course offered a fantastic and simple to follow explanation for concepts that are often portrayed as impossible to understand by mainstream media. Props to Professor Lagerstrom and the rest of the team in developing a course that even a person with a passing interest in physics can follow comprehensively!

Great class, thank you. Just a suggestion for the movie with matter-antimatter fuel comparison to the center of the galaxy , when speaking of 38 kg antimatter, just for comparison perhaps we can convert this to truckloads of coal ... this way people will realize better how much energy it goes to producing 1 gram of antimatter, not even to mention 38 kg ... :")

A well-paced introduction to theory of relativity. The instructor offers a historical angle to the developments, an especially useful perspective for students, beyond the intuition-bending clutter of mathematical derivations. I highly recommend this over other courses on this subject to students of all disciplines, especially those of engineering disciplines.

The professor is a joy to listen to and wish he had more courses on here. While I couldn't follow a couple of times, the benefits of taking a course that goes far beyond our daily experiences is astronomical. I would absolutely recommend this to anyone with even the slightest interest in engaging a more hands on approach to the Special Theory or Relativity.

A complex and challenging topic was presented with great clarity. Some of the early lectures seemed rather slow and laboured, especially if one has some scientific or mathematical training, but getting a clear understanding of the 'basic' topics allowed the more challenging aspects of the course to be cleary understood. Thank you for an excellent course.

An excellent introduction to a fascinating subject. Each individual lecture is short and focused so the amount of new material introduced can always be understood and absorbed by an engaged student. Once key concepts are introduced, they are regularly reinforced in subsequent lectures. Highly recommended for anyone interested in exploring this subject.

The introduction on how to follow the course is crucial in the successful understanding of Einstein's Theory. I thought how Einstein came out with theory of relativity was beyond my ability to comprehend. But the the step by step approach by by Dr Lagerstrom makes the whole theory simple to understand. Thank you very much. I really enjoy this course.

This is a must course those who want to really want to learn more about the theory of relativity which is considered the most confusing theory ,but its actually not true because of this course you can easily understand the course. After completing the course sincerely you would be able to solve basic problems on relativity and even quantum mechanics.
