bhobba reacted to PeterDonis's post in the thread Undergrad Why is gravity a fictitious force? with
Like.
So how is your hypothetical in which we say that a particular tensor is not the metric tensor relevant to this at all? No, it isn't... -
I remember reading it and wondering why he was so proud that his math served no useful purpose other than to view its elegance and...
-
We become aware of how well certain mathematical situations correspond to things we find, work we do, and such very difficult to...

bhobba replied to the thread High School This One Moved Me.You might like to read Hardy's - A Mathematician's Apology. He was, in a sense, proud that what he did had no application, but even he...

We see your feel in usage of "lol", but Mathematics gives us great, great predictive power.

bhobba replied to the thread Graduate Exploring Implicit Assumptions and Foundations of Quantum Mechanics.To elaborate further on Peter's excellent answer (having posted for over 15 years now, they always are), in my recent posts, I have...

Love.
I think it's the other way around. Assuming a wave function amounts to assuming a particular Hilbert space (the space of square... -
bhobba reacted to Peter Morgan's post in the thread Graduate Exploring Implicit Assumptions and Foundations of Quantum Mechanics with Like.
In axiomatic approaches to Quantum Field Theory, which I think any attempt to understand quantum theory will eventually have to engage...

bhobba reacted to PeterDonis's post in the thread Undergrad About wavefunction collapse and explaining single outcomes in different interpretations with Like.
There is no such thing. In "standard quantum mechanics", time evolution is only predicted by the Schrodinger equation in between...

bhobba reacted to PeterDonis's post in the thread Undergrad About wavefunction collapse and explaining single outcomes in different interpretations with Like.
No, this is not correct. An interpretation that claims single outcomes (which at least some versions of "Copenhagen" do--that term is...

According to an interpretation like the MWI, yes. But there are other interpretations that would not agree. Same comment here.

M Math is cool but it dont " matter" lol

Such is Mathematics.

bhobba replied to the thread High School This One Moved Me.I think, at rock bottom, math is motivated by an abstraction of physical reality. Why that abstraction was chosen, and even why to...

I would say (imo) no. But, geometry is definitely an approximation or idealization of what we see in nature. Developing the logical...
