         | If we lived to 200, no doubt many would be saying how sad it is
         | that we average out to around 200 years. To me, that we have
         | what we have against all odds is anything but sad.

       | Sad news. Weinberg was the kind of scientist I like the most:
       | very important results in his career, deep love for what he did
       | and an absolutely no non-sense attitude. It was pretty
       | inspirational to see him always so lucid well into his 80s. Rest
       | in peace professor.

       | Personal observation.
       | 
       | Steven Weinberg made his career as an accomplished disciple of
       | orthodox quantum theoretical physics, making it to the top of the
       | physics/social food chain via hard work developing quantum field
       | theory and getting acknowledged as one of the fathers of Standard
       | Model. But all this without really "rocking the boat" of quantum
       | theory. For a long time he believed quantum theory is fine and
       | was not interested in the deeper questions about it.
       | 
       | He eventually came around and realized and acknowledged that
       | quantum theory has serious systemic problems of
       | arbitrariness/internal consistency related to dichotomy unitary
       | evolution/measurement, to dismay of some self-assured fanboys of
       | QT orthodoxy. This gets him to the Feynman/Schwinger level, as in
       | "did lots of great work, inspired lots of people, and realized
       | the standard narratives have serious problems and wasn't afraid
       | to say it and go his own way".
       | 
       | His last textbook _Lectures on Quantum Mechanics_ is one of the
       | few extraordinarily notable textbooks on quantum theory that came
       | out in last decades. If you want to get deeper into QT after you
       | get through the standard superficial and hand-wavy college
       | course, this is a very good and concise book.

       | I'll share what to me was one of the most impressive aspects of
       | Weinberg's work. I've seen him described as a battle tank -- not
       | the fastest to get moving, but basically unstoppable once he
       | does.
       | 
       | As I was digging into the literature during my research, I
       | noticed an interesting pattern to his work over the decades.
       | There would erupt a "hot" area in applying quantum field theory,
       | and have lots of back and forth and papers making claims,
       | correcting each other, and being corrected. And then a few
       | months/years later would come a Weinberg paper, handling the
       | matter so systematically & thoroughly that there likely won't be
       | any more low-hanging fruit in the area!
       | 
       | The whole thing was really impressive given that he worked
       | largely by himself (most of his papers are single-author), and
       | had among the highest average citation count I've seen for a
       | theoretical physicist. There is a reason his quantum field theory
       | textbook series is highly respected -- he wrought the field piece
       | by piece with his own hands.
       | 
       | Finally, he was an extremely articulate writer, and I have a huge
       | soft spot for his "Dreams of a final theory" -- especially his
       | comments on the relationship between theory & experiment, and the
       | scientific method more generally. I really wish more people read
       | that and got influenced by its depth and nuance.
