Two ways to see it:
- a ring where inverses exist
- a field where multiplication is not necessarily commutative
Quora is crap in many, many senses, but in part due to some bad Stack Overflow policies, it is the best crap we've got for certain (mostly useless) subjects. Until OurBigBook.com dominates the world.
The worst thing about quora is that you cannot subscribe only to certain subjects on your feed. Quora just keeps pumping shit you never subscribed to, no matter what. Ciro, for sport, unfollowed every single idiotic subject it was proposing, but it didn't work, sooner or later Quora just keeps pumping more shit back. Mind you, some of that shit is fun. But it's still shit. Though on second thought, YouTube also randomly decides to reset Ciro's humongous "don't recomend this shitty channel" choices from time to time, which is not much different...
Other terrible things, they just seem to have an incredible ability of making the website worse and more annoying over time! Truly amazing:
- around 2022, quora started showing "related" answers to other questions, possibly before actualy answers to the question itself. This, together with an insane number of inline ads that look very similar to answers, makes it very hard to decide what is an actual answer or not!!! E.g.: people complaining:
- around 2021, quora started expanding any link as a huge preview box that completely takes over the answer, and it is very hard to stop it from doing so
- Quora used to show question details beyond the title by default, but stopped: www.reddit.com/r/OutOfTheLoop/comments/uqyvfp/comment/jd6go1b/?utm_source=share&utm_medium=web2x&context=3
Quora is getting so bad that it is basically being killed by Reddit, especially after they lifted the 6-month hard thread lock...

By Zuckerberg. The selection seems decent. And natural sciences only, which is good. A bit more application oriented than the Nobel Prize it seems, e.g. 2022 separates physics and fundamental physics.
Appears to explain award reasoning even worse than the Nobel Foundation.
This due is a beast, he knows both the physics and the history of physics, and has the patience to teach it. What a blessing: Section "How to teach and learn physics".
Ciro Santilli's admiration for Dyson goes beyond his "unify all the things approach", which Ciro loves, but also extends to the way he talks and the things he says. Dyson is one of Ciro's favorite physicist.
Besides this, he was also very idealistic compassionate, and supported a peaceful resolution until World War II with United Kingdom was basically inevitable. Note that this was a strategic mistake.
Dyson is "hawk nosed" as mentioned in Genius: Richard Feynman and Modern Physics by James Gleick (1994) chapter "Dyson". But he wasn't when he was young, see e.g. i2.wp.com/www.brainpickings.org/wp-content/uploads/2016/03/freemandyson_child-1.jpg?resize=768%2C1064&ssl=1 It sems that his nose just never stopped growing after puberty.
He also has some fun stories, like him practicing night climbing while at Cambridge University, and having walked from Cambridge to London (~86km!) in a day with his wheelchair bound friend.
Ciro Santilli feels that the label child prodigy applies even more so to him than to Feynman and Julian Schwinger.
