The topic of stochastic processes is very valuable in real physics research, yet it is barely mentioned much less taught in the typical physics curriculum (at least in the USA). How did you, personally, acquire your knowledge of stochastic integrals etc? What was your trajectory through books/papers/courses in coming to a useful understanding of stochastic ...

I think we should cancel it. I've been pretty active in chat for the last several months, and I haven't once seen the chat session used as a special event. If anything, it usually falls on a time when things are pretty quiet. I haven't seen it brought up in meta for several years. Any important discussion seems to flow pretty well in comments on meta ...

I enjoyed the chat session and I will certainly attend future AMAs. I've long felt the chat room is an underused resource and it was nice to see the chat room so lively. But ... (there's always a but on these occasions) ... I don't think we attracted many people bar the regulars. I went through the log and I counted 31 questions (after eliminating the ...

thanks very much for accepting the invited speaker invitation as the 1st guest! here are some miscellaneous mostly not-so-formal questions that may be of interest to others, partly based on your own (extensive!) prior dialog in the physics chat room H Bar (which btw for anyone interested and isnt aware, is in a searchable transcript). note some of these can ...

Free-for-all We could just open the chat room for any and all questions from users and answers from the guest. How would the guest keep track of the questions? How would participants keep track of the answers if they’re interrupted by messages from other people?

Since you mentioned closed timelike curves aka "time machines": Are they likely to exist in our universe? And how could they be observationally confirmed in a universe where they exist? If you could maybe give a layman's explanation as well as mathematical detail?

How come you don't like python? Do you think that C++ has advantages for scientific computing in particular?

What role has religion/theology played in your studies?

Even if sadly I could not attend, I had the impression from the post-session comments that it was not so easy to follow the Q-As because of the "background noise" made by side comments, or independent hbar chatting. And @DanielSank (if I recall correctly) suggested a solution: posting AMA questions in boldface, and answering using the reply feature ...

Maybe a discussion on geometries explaining the expansion of the universe, it's acceleration and some connections with quantum mechanics or QFT. On this basis, some thoughts on the arbitrariness of theoretical models for the expansion, how can we limit them down and what's the potential role of QM or QFT on this subject and on observations that may be based ...

Since your interests are GR and Quantum Field Theory, with maybe some insight into Quantum Gravity (QG), could you summarize with some technical reasonings, what is known and what key findings are still needed for Hawking et al's conjecture that the BMS super translation symmetries and conserved charges are the basis for doing away with the information ...

Interview style In this style, users submit questions ahead of time, e.g. here in the meta. A moderator (not necessarily a site moderator) filters the questions, e.g. by meta votes, and then conducts a real-time interview with the guest, in the chat room, based on those questions. Some allowance for on-the-spot questions during the interview would be good. ...

You say you're extremely curious about weak measurements. Can you explain to a quantum physicist who knows nothing about them why? What applications do you have in mind for simulating PT-symmetric Hamiltonians, that is, why are you interested in simulating these Hamiltonians out of all possible Hamiltonians? Or is this more about a challenge for the chip ...

No! A thousand times no! I can't often make them, because, well, school. But I love it when I make chat sessions, and I think that while there've been some quiet ones (the one today, I see, was only a few messages, which probably inspired this post) they overall have been a great thing. Just because something fails once or twice doesn't mean you chuck the ...

Is the IBM's quantum experience worthwhile? Do they really run your code on a real quantum computer and how long does it take to get the results? Is IBM's quantum experience more for fun or can you write code that gives you interesting results that you wouldn't have access to otherwise?

I have figured out your real name, and many other details you did not publish. The "The works of the Lord..." quote helped narrow down the university where you did your undergrad degree, I know you are doing a PhD in Bristol, and then things fell into place surprisingly quickly. So you can confirm it while giving others a sporting chance at figuring it out ...

What is the necessary mathematical/physical background for general relativity and quantum field theory? If you had to pick one book as an introduction to GR and one as an introduction to QFT, what would they be? What are the standard "advanced" references for GR and QFT (books, seminal papers)? What is the standard introduction to time travel research? How ...

In order to also have it here: We will likely discuss Chat and the moderation thereof unless no one present is interested.

This is similar to DanielSank's idea. First a meta question is made, asking what questions should be asked to the subject of the AMA. People post their questions as answers to this meta post. Then, there is a period of time where people upvote the questions they want to see answered. Maybe these get community wiki'd to not mess up rep too much. After this ...
