スタンフォード大学(Stanford University) による Understanding Einstein: The Special Theory of Relativity の受講者のレビューおよびフィードバック



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!

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.

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.

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.

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!

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.

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.
