No Understanding period
You could have stopped after 'concerns of his understanding'. Whether Science, Or Anything Else, he has NO Understanding. His academic level of whatever degree of science he has will only carry so far, again, as with anything else. Without True Knowledge that includes the branch of Common Sense, nothing can be done let alone built, furthermore, become solid & permanent. We all need to hope for Good Luck and good riddance of all things and People not aligned with Mother Nature, SCIENCE! Wisdom Is that Foundation.
