Sobre o curso

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.

Hats off to the professor for being able to explain such mind-boggling concepts about the very nature of existence in an entertaining and intuitive way. One of my favorite courses on Coursera by far!

Es un curso largo y lento pero permite aprender los fundamentos de la teoria y retenerlos para siempre. Buen curso.

Since such online courses became available some years ago, I have followed a number of them on different subjects and on different platforms. This course is simply outstanding. It is hard to imagine how Dr Lagerstrom's construction of the course might be improved upon.

Starting from some very basic principles and with the help of a little simple school algebra, step by step he progressively lays out for us some of the counter-intuitive yet fundamental rules by which the universe functions. Each step is in itself simple, logical, and well within the scope of the most average of learners. But upon course completion, since the student has followed the entire process step by step from basic principles, they emerge with a depth of understanding of apparently complex matters that prove not to be impenetrable at all.

Dr Lagerstrom has managed to show that nobody needs to be afraid of this subject, or be concerned that it is somehow beyond their understanding. Not only is special relativity comprehensible, it may be deeply understood, starting from a few basic tenets, and that is a form of understanding that goes far beyond merely a grasp of the principles of a theory.

It has been very interesting and exciting to follow this course.

It was also challenging to complete it with a quite good comprehension of the subject. However there are some concepts I'll have to review trying a better understanding.

I have really enjoyed the way how professor Lagerstrom explains the concepts in a so plain manner.

Thank you for doing it so well.

Kind Regards.

A good balance of qualitative and quantitative elements. Perfect for someone who is interested in the Special Theory of Relativity but did not get enough from introductory books.

Excellent Prof , Excellent Resources. My only drawback is that prof is a bit excessive repetitive, rest everything is fine.

a very thorough introduction to special relativity, as a layman, I have gained immense insight & basic understanding. Thanks prof Lagerstrom!!!!

Really interesting topic but can get a little boring

At first, it really seems to be very slow paced, but latter you realize that those initial concepts were so key to the analysis and concepts in during latter lectures. The professor seemed to be very dedicated, and taught everything from the ground-up; which was really a help and thus, there does not arises a moment when you seriously struggle about the topic being discussed. HATS OFF to the professor for teaching in such a simplistic and conceivable fashion.

This course is superb, covers easyly all the aspects of the special theory of relativity

This was a great course which is taught by a passionate and patient lecturer. The whole 8 weeks covers the first half of Einstein's famous paper in detail. The pace can be slow, but of course you can always speed up the videos. The mathematics is very approachable - school level algebra is all you need. The only other prerequisite is a basic understanding of light and electromagnetic waves.

The course was really good. But the discussion forum was not pleasant. Due to the unruly behaviour of this person named Thomas Lahn

Very in Depth for if it is your first time learning. If you have already read about General and Special Relativity it doesn't tell you very much more than what you already know. Either way it is a great course.

Than You so much this course has really influenced my life at such great heights

It has also made me give more recognition to our Bible Family for all their great accomplishments.

Not much of mathematical inclination. But the Prof. is really of high standard and he makes sure that you understand everything by the end of any topic as he will run by each topic more than once. Its an introductory course but induces a great amount of interest to learn more!

I disliked really slow speed of formulas derivation, simple operations like cancelling out terms are done in multiple steps. Like for children that only starting study mathematics. Otherwise great course!

A comprehensive introduction to the subject, somewhat spoiled by the unrelenting reiteration of the most basics concepts in the earlier parts of the course. A bit of a pity, since the lecturer is a fairly engaging speaker when he is not busy interrupting the flow of his argument with mind–numbing repetition.

Well taught and structured course, gives a more quantitative understanding of some of the outcomes.

I think a chapter on momentum and energy conservation would be interesting, I liked the examples and the treatment of the paradoxes, very good course.

It's a good course to start understanding Relativistic Physics. Nothing rigorous though.

The lectures are amazingly easy to understand. Overall liked it.

The content is really good. The quality of the content is excellent. The instructor's pedagogical skills are excellent as well.

The only criticism I have is with the length of the videos. I feel they could be shortened. Other than that, one of the best introductory courses for Special Relativity.

Very good introductory course, clear and well designed, with a nice emphasis on the key concepts of the special theory of relativity. The mathematical background required is very light, hence the quantitative analysis of various examples and situations is limited.
