    I really like World Science University class in Special Relativity. There are some drawbacks though. The major ones is that the videos are two small on the screen to watch. The equations that Brian Greene writes on the board is very hard to read, an…

    Dear Reader

    I did masters in physics and read lot about relativity but found some flaws and need to discuss through phone or by email.

    Please guide. I will be thankful to you in this context.

    Waiting for your valuable reply.

    Best regards
