To Professor Rittel hello,
This semester I attended the Materials Failure course and wanted to say thank you.
The course was interesting and very useful and the knowledge I took from it gave me many tools as well as different angles for looking at a problem.
Although I was not a regular attendant at the lectures (system constraints) I saw them all on video and I wanted to say that I had the privilege of hearing from you on this fascinating topic and therefore I would like to thank you.
Hopefully our paths will intersect in more courses.
