The computer simulations are astounding and so useful to me. Max Tegmark is one of the best in helping ‘armchair physicist/cosmologist”, such as myself, understand. Thank you. I am really enjoying this course.

I am finding the math challenging and I am repeating this Module. I love c=foot/nanosecond. I find that exciting. Yet, I haven’t done any geometry in over 40 years. I am refreshing myself with you tube geometry.

I also want to thank you for providing these classes to the public, for free no less! I have enjoyed three courses already and I have learned so much. They have really stretched my mind, so to speak.

I am determined to make it through Special Relativity Math Course if it takes me the next next year to do so.

I think collaboration is more important,. Competition often brings out the very worst in people.

Density increases

“Real estate in space is abundant and cheap.”

I am captivated by this course.

Oh my! I have the desire to understand this, but I don’t yet. I will keep plugging at it.

I love your demonstration of time dilation. Physics for dummies – thank you!
