It's quite simple really. It's a set of instructions to Prof Hawking's gardener. He's having a Euclidian path built (presumably some sort of fancy brickwork) and the rest is instructions that it's okay to tread on the trivial metrics (a sort of daisy) but to be careful with the non-trivial metrics. I think the rest of it is just a case of not being able to read his writing.
I work as a Supervisor in a production facility, and I sent one of the above articles to my fellow Supervisors and I told them that while we have many challenges to face during the day, we don't have anything on this guy.
I've always wondered if it is because of Stephen Hawkins' affliction that he is brilliant or whether he would have been able to do even more had he not been. Either or, there's now hope to find my missing socks in the washer.
He did not always have his condition (ALS). In a Brief History of Time, he referenced a choice of not pursuing his career (I'm blanking on the exact title he was going for) since the doctor's told him he would be dead before he completed.
But you may have something. In the same book, he states that he thinks about his theories a lot when trying to go to sleep, since with his condition it takes a long time.
I'm afraid I have to disagree with that. He was going along the right path with his first theory. He's clearly not thinking clearly in his old age. Being on the Simpsons and Conan has gone to his head.
I thought the ideas themself were pretty cool, one the journalists boiled them down enough to understand them. I never liked the idea that a black hole simply swallowed stuff and it never came out. I like to hear that stuff can get back out, although in "mangled bits"
