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!

A great course for beginners. While it does not cover a large number of topics, the ones it does, it tries to do slowly, thoroughly and with clarity of thought.

very interesting course, it convers the basics of the theory of relativity, also putting it in an historical context, outstanding teacher

An experience of discovery into the perspective of 1905, and the path of reasoning.

Professor Lagerstrom does a superb job of presenting Einstein's special theory of relativity. There is a good balance of history, high school level mathematics and thought experimentation. I have been studying Einstein's special theory of relativity, mostly by reading books, for over 60 years and this course solidified the theory in my mind. I actually have two good friends named Alice and Bob, who are unrelated to the course heroine and hero. The real heroes in the course are Professors Einstein and Lagerstrom.

A very thoroughly planned and executed course. It is obvious that the professor/Stanford spent a significant amount of time in determining the content/videos and the supporting quizzes and tests. Ideally suited for those with basic math skills up through algebra but not calculus. The inclusion of the motivating historical aspects is something that is not always covered in similar courses.

This is truly one of the more interesting (and fun) courses at Coursera. The presenter takes the student step by step through the intricacies of understanding the special theory of relativity such that, even with a very limited background in math and physics, you will be able to appreciate the impact this theory had on scientific thinking back when it was published and how it, and its 'big brother, the general theory of relativity, shape scientific endeavors presently.

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.

second time in my life I had a course at this level of clarity.

Extremely gifted teacher

Very carefully crafted course by Prof. Lagerstrom, starts with basic concepts so that every curious mind could grasp it. Always wanted to learn about Einstein's special relativity theory & now I know it.

We made haste slowly. :)

And, it helped absorb some concepts which I've read multiple times over and over but could never accept.

Despite having completed the course once, I keep revisiting the videos every now and then. It helps me further get the concepts as a part of my intuition.

A bit tedious sometimes but quite rewarding once completed, especially topics covered during last week (Week 8)

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.
