Brian Bernard is an Associate Professor of Engineering at Schreiner University in Kerrville, TX. This channel is meant to help engineering students pass their classes and graduate on time. I know you are busy so I hope you will find my videos to contain as much good information as I can cram into the shortest runtime possible. I try to be funny, but don't always succeed - luckily my cats make occasional appearances to save the day.
