Do not miss P.S. section at the end. It is very inspiring! Quote:

"We’re not researchers at all. We’re just two people who became obsessed with a problem and put their meager knowledge to use, beating rocks against rocks in different configurations until something resembling a spearhead came out. ... You, too, can do something like this. Find a problem. Become obsessed with it. Learn everything you can about it. Fall down dead ends. Give up, and then keep thinking about the problem at night. Have Eureka moments that lead you down other dead ends. ... "

Sounds to me like they are superb researchers.

(Eureka moments leading you down more deadends is so wel put too.)

Yup, this IS research from my perspective.

Superb researchers indeed. Most would lose all enthusiasm after the riddle was "solved". Yet they still found it in them to document.

As a former researcher I can attest this is how research is done :-)
