mood when I come up a new research idea

I’ll be at the APS satellite meeting in Hong Kong a week later but I genuinely don’t see how this meeting is related to the actual legit APS march meeting in the US, aside from having APS in its name

Its indeed a legit meeting tho

an electron on earth and an electron ten billion lightyears away are exactly the same. same mass, same charge.
I find it kind of wild.

fundamental physics concepts, like observables, state vectors, vector potentials, etc., you can’t measure any of them. You only measure some correlations. Yet our entire understanding of the universe is based on these practically nonexistent concepts.
let that sink in.

imo if I come up with research ideas independently, the chance of it exactly coincides with someone else's work is quite low. We may be covering the same problem but mostly likely the attack angle will be different

i feel that a lot of academic collabs are diplomatic

it's not a positive thing for the field that quantum computing has captured Elon Musk's attention.

how to identify bs posts on quantum computing
- posts not from researchers with strong publication records are bs
- posts hyping a quantum era within this decade are bs
- posts involving geopolitical topics are bs (100%)
- posts that are non-academic are mostly likely bs

Over half of the quantum people on X are hypsters and should not be followed by anyone. Things look better here on Bluesky.

I find some people hyping quantum race as the new nuclear arms race. I don’t think these people have any understanding of what a quantum computer is capable of. Plus, it’s very disrespectful to the 200000 lives lost in Hiroshima and Nagasaki.

Wow, that’s a really large group. How do you manage to keep track of everyone’s research?

i keep thinking that academic may not be a good career path for adhd folks, mostly due to our poor short-term memory. we can have fantastic research ideas but putting them out to papers can be extremely challenging.

done.
Yes, it’s doable, from virtually nothing (some very vague idea), to a paper, in one month, all by oneself, working alone.

The fact that high-speed rail is not a thing in the US is mind-boggling. When I was a student flying was too expensive (and not very accessible if you live in remote places) and driving for longer than 3 hours was painful

it's weird that whenver I feel that I can prove something, that whatever thing instantly becomes trivial and apparently not worth proving
