its a great dress

holy shit heyy haha

how was your birthday??

🫡 more napping

Yeah, but I don't think I have symptoms of long covid. I have always been fatigued.

There are a few conversations from last week I am going to circle back to after tomorrow

(I have a deadline to make 😇)

trying to discern the games you're playing, in a normal way

photo elides slides

i keep drawing copies of the 'Stupid Idiot Loser' somehow??

tarot reading with mugs would be..
a challenge, i would think.

it definitely does portend evil, though, when you pick up your mug upside down

im sure your knowledge of calculus is paying dividends

kick the ball as hard as you can

this pic is shrouded in mystery

It's Sunday afternoon, and you know what that means. Form a single file line and please submit your #MathCoffeeSelfie for inspection.

surely i can fix this by simply powering through

I'm not sure

well, yeah, sometimes i do go catatonic thinking about particles

i find thinking very tiring. i get exhausted trying to understand something and then i take a nap.

idk i just feel so scattered, and forgetful, and unfocused. things that were clear become confused again. i read something and forget what i read. i don't know how else to account for how much energy has been expended making such little progress.

i think i have a learning disability

suppose two regions of space were identical. it still matters whether one or both were between you and I; it controls how long it takes for me to reach you. so these otherwise identical patches are seemingly distinct at least in number. again, idk how to do away with space (in favor of objects, etc)

extremely on-point of him to have removed some of the content from the story

I am sort of given to the idea that spacetime points have identity, maybe only because this makes things easier on me. I do not understand how to understand spacetime as being just relational. You unroll the carpet first; then you put your toys on it.

I wonder what Leibniz would say about the dollars in my bank account

Yet for motions in space, the symmetry group also acts on these and it seems (to me) like they should be identified; the universe could not have been 5m to the left.

i do feel you. i wonder if spacetime points are non-identical indiscernables. Minkowski spacetime has a transitive symmetry group, so if you quotiented by symmetry you would get one point; thats definitely inappropriate.

There is a discussion in Schwartz that indicates the positronium states are single-particle states. On the other hand, then it is obscure in what sense it is made out of a positron and an electron.

are the positronium states in the single-particle or two-particle sector?

right, but I kind of expect the positronium state to be a single-particle state (parameterized by one momentum). Is that correct? Do they have their own raising, lowering, & number operator, and Fock sector?

Does S-Matrix theory really only work when there's a correspondence fields <-> particles?

Do you know how I can write these creation-annihilation operators?

(I'm also confused about the connection imaginary mass <--> unstable particle)

Even in QED, though, we don't only have electrons, positrons, and photons; we also have positronium. Does positronium get its own Fock space factor within H_out?
