You will have to tell them. 47 years ago when I started attending college one could be proficient in most of the science and math that was known. A scant 30 years prior to that time all the chemistry known was composed and taught from a single text book. What was superior knowledge then is but general and basic knowledge today. There has been a avalanche of new thought, methods, and specialties. I hardly know what qualifies as science today other than what is required by method and it would appear to be abused. My apology but I would defer.
I can understand that.
