    A Where to find black hole datasets

    I do have a laptop with linux but it's a decade old, the poor thing. I'm not gonna make it crunch numbers, that's elderly abuse!

    A Where to find black hole datasets

    Oh I haven't started analyzing it yet. Other things came up. But their own program seems promising, at least to preprocess the data a little. The raw data seems very complex. But it's linux only. I'll have to see how to deal with that eventually. EDIT: You can find more about Chandra, data and...

    A Where to find black hole datasets

    I found a few, yeah. But most are not complete enough, or were preprocessed in inconvenient ways for what I wanted. I did eventually find Chandra's website, which provides all kinds of data and even a data analysis tool. And the downloads worked!

    A Where to find black hole datasets

    Hi everyone, I'm trying to download the 4XMM-DR9 EPIC Source Catalogue for some X-ray spectral analysis near black holes. The download links on the XMM-Newton site are broken, and the archive ones are working but the actual download keeps failing before reaching 10% completion (it's a large...

    Job Skills Switching careers to software development

    You are right. It did not occur to me this was important information. But if anyone's curious, I did get a job as a developer! :) Good benefits and decent starting salary. I still feel bad about leaving the academia, and hopefully I can still integrate physics research in my life. For anyone...

    I Could spacetime be non-orientable?

    (parachuting in this conversation) I believe chirality would be an issue in this universe.

    Job Skills Switching careers to software development

    Hi all In my country, and with the pandemic aggravating affairs, an academic career seems unlikely for me at the moment. It's what I have been preparing for, I finished my PhD and started looking into post doc positions nearby, but no luck so far. So people advised me to try becoming a software...

    I Average of prime factors growth

    Sigh. Sometimes I hate my ADD-riddled brain. I'm staring at your code, then at my code, then at my plot, then at your data, and I could not understand why we were getting different results. In my laziness I did the fit without using the actual numbers, but their indices instead! since I was...

    I Average of prime factors growth

    (I had a gif of Mike Myers saying "ONE MILLION DOLLARS" but it was causing problems to post it here.) Anyway, a million. I know, I know, in the realm of number theory this must be laughably small.

    I Average of prime factors growth

    That's unexpected. I got some really specific numbers in there and I can't find a good fit with just that integration constant. I wonder if that fit I got only works for that range I used.

    I Average of prime factors growth

    Nice! The expression is definitely recognizable. The differences come from counting all factors, not just the unique prime factors. Do you have any more theorems in that hat of yours that could include multiplicities as well?

    I Average of prime factors growth

    Hi there, bored physicist here. I wondered about factorization so I made some plots and a model fit to satiate my curiosity, but it only made me more curious. Now I just want the answers! I didn't know which prefix to use. "Hobbyist" seemed more appropriate but we don't have that so I went with...

    How to surround myself with other physicists/students outside of academia?

    Maybe you're right but I do see other equally competitive fields with a more exciting online presence. Computer science, for example. They can keep their work under wraps and still engage the community about recently published works, sharing opinions and stuff like that. Or, even more useful, to...

    How to surround myself with other physicists/students outside of academia?

    No, it's Brazil. I didn't mention because I was more interested in online solutions. Brazil is a large country with lots of physics departments scattered around, but none near me at the moment. That mirrors my experience as well. I guess one of the contributing factors is that physics is a...
