PeterDonis replied to the thread Undergrad Relativistic Space Travel: Optimizing Proper Time [Project Hail Mary].Ok, thanks! -
PeterDonis replied to the thread Is A.I. more than the sum of its parts?.The operator controls the computing resources the AI is using. If the operator is forced to shut them down, that shuts down the AI... -
PeterDonis replied to the thread Is A.I. more than the sum of its parts?.You don't think it's reasonable that the operator of an AI should be responsible for what it does? -
PeterDonis replied to the thread Graduate Quaternionic Rays instead of Complex.Moderator's note: Moving thread to the Beyond the Standard Models forum. -
PeterDonis replied to the thread Is A.I. more than the sum of its parts?.In terms of capability, it might be, yes--AIs have lots of capabilities that dogs don't have. But in terms of responsibility--the owner... -
PeterDonis replied to the thread Graduate Why is 0 K unattainable?.A minor point which doesn't affect your main argument: I don't think the energy has to be zero at zero temperature, it just has to be... -
PeterDonis replied to the thread Graduate Topological constrains for the solutions of EFE.No, if ##\Sigma## is maximally symmetric, which is how it was defined in this thread, it is not, as I've already said several times in... -
PeterDonis replied to the thread Undergrad Relativistic Space Travel: Optimizing Proper Time [Project Hail Mary].Btw, an equation for the mass ratio (including the need to turn around and slow down) in terms of just the acceleration and the distance... -
PeterDonis replied to the thread Undergrad Relativistic Space Travel: Optimizing Proper Time [Project Hail Mary].No, you're right, it doesn't. But I suspect that that might be the underlying error in the calculations behind the scenario in the book... -
PeterDonis replied to the thread Is A.I. more than the sum of its parts?.I don't think it's all that similar. In the case you reference, an editor used ChatGPT and it gave him fabricated information about a... -
PeterDonis replied to the thread Graduate Why is 0 K unattainable?.Per my previous comment on this, I don't think it makes sense to describe this in terms of temperature. I think a fair description in... -
PeterDonis replied to the thread Graduate Why is 0 K unattainable?.It looks reasonable to me, but I'm not sure if this argument appears in the form you give it in the literature. For example, it doesn't... -
PeterDonis replied to the thread Graduate Why is 0 K unattainable?.I've seen that heuristic argument (though not in actual peer-reviewed literature), but I don' think it's correct. The uncertainty...
