## kin Ruth

I want some one who can help me know that subject better

## Vale

I would also add the Introduction to Atropysics course on EdX by EPFLx, I´ve recently finished it and do recommend it to anyone looking to learn some of the basics in astrophysics, it also comes with a syllabus from the lectures which was really handy.

## HGerechter

Looked for this course:

Quantum Mechanics and Quantum Computation

via edX

The preview played OK, but the link to the class yields a Not Found page on Edx. Tried edX search without success.

Is this course still available?

## Manoel Cortes Mendez

Thanks. It doesn’t appear to be available anymore. I’ve removed it.
