That makes more sense, since ammonium perchlorate can be shock-sensitive and reacts with various chemicals.

So it's possible this happened while/after synthesizing the sodium perchlorate into ammonium perchlorate.

Edit: I am maybe jumping the gun here, I'm not sure at all whether this was being synthesized at time of explosion.

You've misread the passive language here. 'no prints were recovered' can mean that they tried to find prints and couldn't, or that they never even bothered to try getting prints off the gun.

Article on it.

  • Article says 'mishandling'.
  • Shipment was in two shiploads from China.
  • article also says the fuel type was 'sodium perchlorate'-based.

Thoughts overall on what factors contributed? Is sodium perchlorate super volatile?

Edit: Wikipedia says that sodium perchlorate mixtures used in rockets and fireworks are not shock-sensitive and do not spontaneously detonate.

Ah, wasn't aware. Will have to look into it more.

I like the color choice and flow of yours.

Here's my attempt at making it a monogram.

Same arrangement with fluid lines.

In the case of steam and web browser, the containerization means I can control their access permissions via flatseal. This adds another layer of security, since they're both web-accessing applications, and it's easier than setting up a VM to run those applications.

It was probably a squirrel, my whole life's been one big lie.

When using certain apps I prefer them being containerized on my system. It's case-by-case for me. I keep steam containerized, my web browser containerized, etc.

[–] JayDee@lemmy.sdf.org 6 points 16 hours ago

Yeah, flatseal should come stock with flatpak IMO. You will have to configure many apps to get them to play nice with your system.

[–] JayDee@lemmy.sdf.org 5 points 16 hours ago (11 children)

I use apt and flatpak. They both are good for what they do.

Yeah, that's the nature of mass adoption, is that people you don't like start coming into the community.

This always happens. A community stays intact so long as it stays niche, but once it reaches mass adoption, that community splinters into smaller communities.

The 'Linux community' will eventually cease to exist and will be replaced with communities who use Linux in specific fashions.

I think this is more referring to the play.

This is a question regarding atomic and quantum physics, and any academic input would be appreciated. I am wanting some input on what level of trust I should put into this "Quicycle" group. It's a think tank comprised of supposed Doctors from CERN and research groups, and states their names. alot of their stuff raises red flags for me, though.

To preface, I was working on understanding how exactly, in 3d space, electron orbitals affect the magnetic field of their atoms. I'm wanting to better understand why atoms like Iron are more magnetic than others. I am not heavily plugged into the physics community, though - I'm mostly just learning out of personal curiosity.

I stumbled upon this group's periodic table of atomic orbitals, and it seems accurate on its face to a layman like myself. However, I start trying to research some of the terms and they're proposing things I've never heard of like pd-hybridization (where the p and d electron orbitals merge(?) to produce a hybrid orbital(?)).

I decided to look over their site with more rigor and I'm seeing things like Vivian Robinson: The Common Sense Universe (talking about 'common sense' when talking about quantum and "sub-quantum" mechanics seems really screwy) and M.A.R.T. (yet another theory of everything attempt) and I get a sinking feeling that nothing in this website is trustworthy for learning more in-depth physics.

Does any of this stuff look right to any Lemmy physicists?
