mad mathematician's latest activity
-
mad mathematician replied to the thread Graduate Couldn't the cosmological constant also have some sort of "dynamics"?.I wonder how difficult it would be to to write down a model where it changes with time. -
mad mathematician reacted to PeterDonis's post in the thread Graduate Couldn't the cosmological constant also have some sort of "dynamics"? with
Like.
Because a constant is the simplest model, and we have no evidence that it's not constant, so we use the simplest model that's consistent... -
mad mathematician replied to the thread Graduate New ideas on confinement and meson masses from Brazil.Complex Gauge theory, sounds someithing that resonates with the book by Yurin Manin.

mad mathematician posted the thread Graduate Couldn't the cosmological constant also have some sort of "dynamics"? in Cosmology.Why should we believe that the cosmological constant is indeed a constant, and not another parameter that changes with spacetime...

mad mathematician replied to the thread Particle Neutrino Particle Physics Book.Try Mark Thomson's book on particle theory.

mad mathematician replied to the thread Announcement RIP Vanadium 50.My sincere condolences, we had some fierce posts in beyond SM of particles. Though I can't tell if he posted when I started back in 2002.

mad mathematician reacted to Fra's post in the thread Graduate How to fix Relativistic QM so it's consistent? with Like.
I think the OP means RQM=RelativisticQM, not RQM=Rovellis RelationalQM, are you talking anout the same thing? IMO, from perspective of...

mad mathematician replied to the thread Undergrad Infinite number of spatial dimensions (maybe also time dimensions).Hi @anuttarasammyak I know what is a Hilbert space. x in you case is spatial coordinate, so if I want inifinite number of coordinates...

mad mathematician replied to the thread Undergrad Infinite number of spatial dimensions (maybe also time dimensions).but spacetime in QM isn't inifinite dimensional in spatial coordinates.

mad mathematician posted the thread Undergrad Infinite number of spatial dimensions (maybe also time dimensions) in Beyond the Standard Models.How would one build mathematically an infinite number of spatial dimensions theory? I can concieve mathematically an n-th vector or...

mad mathematician replied to the thread Undergrad The Universe is No Simulation.As for Sokal-like hoax I don't really know. I mean Bogdanov brothers got their doctor diplomas for a nonsense-type of publication. So...

mad mathematician replied to the thread Undergrad The Universe is No Simulation.The classical computer is binary. As for Boolean algebra, it seems there are several Boolean algebras; in Machover and Bell there's a...

mad mathematician replied to the thread Undergrad The Power of QM and QFT.Well you have two options Quantum vs Classical. Now infinities are all over physics (classical and quantum), the self energy of an...

mad mathematician reacted to renormalize's post in the thread Graduate How to fix Relativistic QM so it's consistent? with Like.
The following is taken from Bjorken and Drell, Relativistic Quantum Mechanics (1964), pp. 5-6: So the problem with the Klein-Gordon...

mad mathematician replied to the thread Graduate How to fix Relativistic QM so it's consistent?.What do you mean "apply it to Klein Gordon"? do you mean we assume that if psi satisfies KG then psi doesn't satisfy the conservation...
