此课程适用人群: This course is open to anyone willing to put in some time and effort to understand Einstein and his special theory of relativity. Although it will help you to have a basic understanding of algebra, much of the analysis is qualitative or only semi-quantitative. In addition, a math review video lecture is provided at the beginning of the course.

I loved this course.

This fascinating course presented by a historian of science covers not just the basics of special relativity but the historical context as well. The lecturer starts off each week with some Einstein quotes and goes to great depths to explain the basic concepts at a level that is accessible to students with minimal experience of maths and physics. The concepts are firmly drilled in with plenty of optional quizzes after each mini-topic, and a summary video at the end of each week. The lectures are long but anyone short on time has the option to go straight to the weekly summary/quiz, and/or play videos at up to 2x speed (especially in weeks 2 and 3).

The main highlight for me was the explanation of the famous Twins Paradox and other related paradoxes which are resolved by understanding frames of reference and the relativity of simultaneity. Another bonus was an explanation of the bending of light by gravity through a simple thought experiment involving an accelerated elevator.

Some important topics not covered in the course, or only hinted at, are: treatment of accelerated reference frames (required to derive the relativistic rocket equations), relativistic momentum and kinetic energy (required to calculate the rocket fuel required) and relativistic energy (used to derive Einstein's mass-energy equivalence formula).

Overall I highly recommend the course to anyone with the time and inclination.

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

Very well paced, with very clear explanations and interesting insights.
