Nonsense. Some of the most beautiful elegant proofs in all of math (and science) are wordless drawings.
First, there are no proofs in science. Second, if you can find a published paper that has a proof that consists of nothing but a "wordless drawing", I'd love to see it.
There are some "proofs" of the pythagorean theorem which are little more than pictures, but you have to know what you are looking at.
What this article describes is nothing of the sort.
There is no such thing as proof by picture.
