Very interesting course. It gave me a basic understanding of Special theory of relativity.

Excellent course. Excellent instructor. Well worth the time!

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 ... :")

Oddly, given subject matter, this is a very old school course - professor lecturing before a white board. Yet it works! I finally understand the Special Theory of Relativity and am convinced that time dilation and length contraction are real. Course is well paced. Outlines provided for taking notes for each session are very helpful. Quizzes and tests are appropriate. Highly recommend to anyone who has ever wondered if on might actually travel to another galaxy and return alive.

Outstanding course!

The teacher was very good and made it easier to understand some of the more difficult topics.The course was very interesting and gave me a very good insight into Einsteins special theory of relativity.

A very easy way to learn a very complicated theory

It's slow but very thorough

Great course!

Thanks to Professor Lagerstrom for his patient and clear way of teaching and explaining things. Looking forward for a course on General Theory of Relativity tought buy him.

This is a very good course! any thanks to professor Lagerstrom.

quite enlightening! Great job Mr. Randles

Ennobling experience as Einstein said in one of his quotes. Thank you Professor for making things so simple and interesting. I was struggling to understand these key concepts of relativity from a long time. Would definitely join other courses similar to this one.

An invigorating course that provides foundational understanding of the core concepts and theories in physics and Einstein's ingenuity. Highly recommended.

Fantastic course that is designed for anyone with at least basic knowledge of mathematics.

Larry is the best-I highly recommend! I loved this course and really enjoyed exploring these concepts. It is very well put together in a way that gives you time to ponder and try to truly understand the theory before getting to the "cool stuff." I will miss this weekly adventure!

Awesome course!! Professor explained the concepts in a very simple manner and yet explained them in great details....

The teacher is great. He explains all the concepts very well. It was a wonderful course.

Course was well organised and with mostly qualitative discussions. This course is apt for beginners.

A fantastic course by a fantastic teacher. Enthusiastic and interesting and most importantly clearly explaining the subject matter. I wouldn't hesitate to recommend this course to anyone and to take any other course run by Larry Randles Lagerstrom.

Professor Lagerstrom is a great teacher and the course is well organized. While still a little complex for someone with rudimentary or fairly stale science knowledge, Professor Lagerstrom's approach is easy to follow and understand. I especially like his summaries at the end of the course which put together the complex mathematics into simple

though i have read lots of popular physics before, nothing ever explained lorentz contraction and time dliation like dr lagerstrom! really helpful new understanding.

great course.just enough math .repition of key points really helped.will miss it.thanks

A very useful insight into Einstein and his Special Theory of Relativity

A brilliant course presented with knowledge and passion by Prof. Lagerstrom. It is very easy with minimal dependence on Mathematics. It certainly has inspired me to follow on to learn more about the Special and General theories. Thank you for providing the list of texts.

It is a very good course that is well organized and explained. The instructor was extremely great; he uses a lot of examples and thought experiments to help us imagine the situation. Although relativity is such a hard topic to learn for many people, the approach of instruction in this course makes it interesting and easy to be comprehended. After the course, you will find that you have learnt a great amount of knowledge about the topic and you can go into discussions about relativity related issues, even that you don't feel stressed during the course by the enormous amount of materials. Moreover, this course is suitable for anyone interested in the topic, even without much knowledge in physics before, because the course explains everything even the basic concepts.

I learnt A LOT from this course, and it encouraged me to love the topic, get excited about online learning and go even deeper in relativity study.

Excellent course, It lets You understand clearly the strange nature works.
