Weirdly it's not like the author is some crackpot nobody, he has actual papers under his belt[1] and is a Senior Lecturer[2] (although not at a particularly prestigious university, admittedly).
His other papers are all in solid-state physics. He's a real scientist playing around outside his domain, discovering a well-known result, and writing a fun letter about it to a low-impact journal.
All of which is fine. It just requires a bit more context than the headline yields. If this had linked to his blog, it would make a lot more sense.
