ehhgg, die german post (DHL) now demands a 6€ fee for handling parcels that have been taxed by customs

@ajroach42 you know, PTScientists stands for "Part-Time-Scientists" because originally they did it as a hobby. but along the way it turned into a full-time occupation so they concatenated the name and basically scrapped the meaning

@ajroach42 I've been to a semi-public presentation of PTScientists last summer where they talked about their plans and now I'm seeing this pop up all over the news. Makes me feel kinda special ^^

after exam-time is over I always feel somewhat empty, because suddenly there's so much free time and your main purpose of the last days just vanishes

@noelle damn, I could actually understand what it said.
but yeah, screw those kanjis

@sten probably not anytime in the near future

@sten yeah, but the mass distribution of a neutron star is fairly invariant under rotation, so you'd need at least a binary system of neutron stars revolving around their gravitational center

if you're trying to build a transmitter for gravitational waves, say a spinning metal rod, remember: emitted power scales only with the square of the mass but sixth power of frequency

the line is NOT a fit but the prediction of general relativity.
Looks pretty good if you ask me. https://octodon.social/media/dsNOth1zhSsjpIyaULc

ok, so apparently LIGOs observations are only the first time we were able to DIRECTLY detect gravitational waves.
Hulse&Taylor already uncovered indirect evidence in 1974+

@kaye try talking about electroweak symmetry breaking and the higgs mechanism, this will bring every conversation to a grinding halt

@Christ_OFF this is actually mind-boggling.

@lucasrizoli I should really get around to finally install LineageOS instead

@sten good luck, it's certainly not an easy topic. He even put in a quote from Feynman at the beginning:
"If you are not confused by quantum physics then you haven't really understood it." ^^

@sten oh yeah, not a big fan of all that stuff either. But I feel like Griffith is a bit more on the practical side and keeps the math-part to the necessary level required to understand the physics involved.

@nev for some reason the ? wildcard is somehow much less well known than *

@sten When it comes to QM textbooks my personal favorite is definitely "Introduction to Quantum Mechanics" by David J. Griffith. It's written in a very enjoyable way unlike most other books, although I guess it does require some linear algebra 'n stuff as well.
