I am told of a guy who did his math PhD on set theory. He defined a set with some properties and then set out to explore more properties and prove related theorems. Shortly before he was to graduate, it was also proven that it had been the empty set he had been working on.

There were some deliberations as to whether this was a valid PhD. Eventually he was indeed awarded his PhD. He went on to a NY telecom firm to work on data compression.

@ShreyshDeshmukh That sounds tough. Especially given that so many people out there invent new words for old concepts and then sell entire books explaining the new words.

@JakeArkinstall The comments suggest that it is a common risk in the discipline. It likely takes advanced math to prove the set is nonempty and one should keep an eye on the possibility it's empty. Not trivial. Generally, it's good to remember that emptiness can disguise itself very well.

@MarkovMagnifico @keysmashbandit "This robot dog truly represents a model of [pet-dogness] that either is or can shortly be analogous to that of dogs in part or in full. all else is downstream of that.".Yes, some dog people might yell at you. Many more would find it plain ridiculous. Can you see why?

@pageman "The work likely involved non-trivial properties, where proving the set is empty required sophisticated mathematical machinery." .Other comments indeed suggest that it's a common risk in this discipline to end up with the empty set.

@MarkovMagnifico @keysmashbandit We are trying to figure out why people "yell at" her. Surely it's not because she says AI can appear to reason in sentences and create paintings "in the style of". The level of ridiculousness in AI hype is similar to the dog case. The ick overshadows it in the case of humans.

@MarkovMagnifico @keysmashbandit A dog person will never prefer this "better plastic toy" to a real dog no matter how more capable it is. A work horse, sure, you want the best, that's why we have cars and tractors; a shepherd's dog perhaps, so the shepherd even bevomes unnecessary. But not *your dog.*.

@hzjoe03 I was wondering: did you know the word "odyssey" before you heard about the book? It is an often used word in the English language. The word's origin is precisely this book. This alone indicates some influence on the English language. The influence predates America.

I was looking for sth in the index of Mattuck's book, when I happened upon the entry "poodle process," have you ever heard of it? The entry pointed to p.87, but the term "poodle process" is nowhere to be found on p.87. On the other hand, this Feynman diagram is pictured on p.87:

On think tanks and consulting firms.
If you're ever worried that your forecasts might be wrong, remember that in 1986, a UK consulting firm predicted that the Soviet Union would land men on Mars by 1994.

@skdh The preprint results have not been "peer reviewed," i.e., screened against nonsense. But at what point are scientific results "final" (this article's term) and public-ready? The answer may depend on the subject. But the question is important in the context of "open science.".

I've had colleagues who could have done this unknowingly. But we are more posh nowadays.
This man was a teacher for 40 years. At year 2 or 3, on Picture Day, he realized he'd worn the same outfit as the previous year, so he got the idea to continue to do so for his whole teaching career (1973-2012)
