Physicist Jesús Rogel-Salazar has created a couple of videos on using LaTeX and posted them on his blog Quantum Tunnel.
The first video is Using LaTeX to write mathematics and is a very quick overview of LaTex, and the second is Structured documents in LaTeX a more in-depth treatment of creating documents.
Thanks a lot for including a link to the tutorials! Look forward to getting some feedback.
No worries. Figure people in my two departments will find these of interest and may well have some feedback.
