Then what is a 'heavy academic background' then?
Phd, Professor or similar [peer acknowledged] high level of learning in hard science.
Attendant to the above mentioned, profound background in hard science, we would also expect our hypothetical subject to manifest substantial intellectual capability in other areas (languages etc) thus our subject can thusly be held up as a "polymath" ie: a background replete with a level of academic achievement, of which, can be labeled "heavy".
If you missed that we are talking of a Leonardo Da Vinci, a Von Neumann, Issac Newton or Getbig's Dan Duchaine!
If you are as slow as you appear to be, this "heavy" group does not include Getbig's Mal fucking Pigford or other similarly intellectually inept scumbags!
Clear enough for you?
