at Caltech.
This isn't really about the 90-hour workweek. Occasionally, it transpires that you have 90 hours of work to do and only one week to do it in.
What's repellant is that the words "at Caltech" add no meaning to that sentence. They are included purely to argue from authority:
"You will find that this is the norm here."
"You will find that this is the norm here at Caltech."
"You will find that this is the norm here at Caltech, and who are you to violate the norms of such a prestigious institution?"
Scientists are supposed to know better than this.
