Know how we all meet different kinds of teachers and college professors during our time in school?

Well...

Weeks ago, my adviser suggested that I should become a student assistant under one of my previous professors. Seeing that someone had applied as student assistant on his billboard, I followed suit, in hopes that I would also become one. He has replied to the first application before I posted my offer.

A week has gone by, and more offers were pinned on his billboard, but there were no replies to any of them. Just the first one.
I don't know if that was a week or two ago, but now...

I received an SMS from an old classmate of mine that she knows another professor who was looking for a student assistant.

I talked to the suggested professor, but she explained that she was more concentrated on looking for those who were availabe 10-11PM every Wednesday. On those days, I have three classes, which means I am not available in the 8:30AM-12PM time frame.

So I went back to check the application that I posted on my previous professor's billboard. It so happens that some other professor was nearby and I told her, "This professor hasn't accepted any of these other applications in a few weeks."

"Haven't you heard? He passed away yesterday due to cardiac arrest."

...After that, I was pretty shocked.
I never had much connection to this person, except that he was my uncle's classmate back in the days(and my mom knows him as well).
Another thing...
I had this class, which was divided into two portions.
He was in charge of the large lecture class, and six other professors handled the recitation sections.
I passed the recitation, but his lectures were known for being...well, technical and difficult.

So...I really don't know what to say about his passing.
