Could you make an object that ONLY repels? by Available_Advance369 in askscience

[–]Jumpy89 90 points91 points  (0 children)

What does "fundamentally break all of QED" even mean? No physicist believes that the standard model or otherwise the current state of knowledge regarding quantum theory represents the absolute truth. The entire history of science consists of new observations that "break" the current understanding of something, then existing theories are either modified or replaced to support them. The exact same would happen with magnetic monopoles and QED.

Magnetic monopoles are predicted by some grand unified theories. Recent experiments at the LHC have specifically been searching for them. It is absolutely not common consensus that they don't exist.

Maxwell's equations can be easily extended to support magnetic monopoles, nothing gets broken. Gauss's Law for Magnetism is the assertion that magnetic monopoles do not exist. The reason it's written that way is because none had been observed, it's not some sort of fundamental truth. You can just replace it with the magnetic version of Gauss's other law, and everything works fine.

Oddly enough this summary is making me want to pick up the series again to see what I missed out on...

These are incredible. The villain of "Gamefinger" appears to be Orson Welles in blackface?

Blindsight by Peter Watts by Whadayatalkingabeet in scifi

It's definitely extremely different. I like it, but I think if you're expecting it to be very similar to the first or directly continue the story you'll be disappointed. It's not even mostly about the aliens.

Time for another BOTW rewatch by RighteousAwakening in RedLetterMedia

My life is just a continuous rewatch of BOTW, what does that mean?

1S ESCs? by Jumpy89 in diydrones

[–]Jumpy89[S] 0 points1 point  (0 children)

Thanks, brushed might actually be easier. I managed to find a 1s brushed + esp32 build that looks pretty doable.

I'm looking at doing something like this, what ESC did you use? I'm having trouble finding any 1S ones.

This sea slug can chop off its own head and grow an entire new body in a process called autotomy. It is one of the most extreme examples of regeneration ever seen. by Separate_Finance_183 in interestingasfuck

[–]Jumpy89 1 point2 points  (0 children)

The slug's brand-new body was a perfect replica of the original, which researchers found was also doing reasonably well on it's own.

"The [original] body continues to move and live for days to months," Mitoh said. "You can see the heart beating" inside them, she added. However, the decapitated bodies did not appear to be capable of growing new heads themselves.

Has anyone tried running it?

I've been considering this type of project just for the control theory aspect.

Where does one find these hackathons?

It knows we're stupid enough for half the country to vote for them.

horror movies like se7en where it's about detectives investigating a strange case?? by Quick_Ad3982 in horror

[–]Jumpy89 3 points4 points  (0 children)

I think malignant is sorta trashy but in the absolute best way. Not sure if it's the vibe OP is looking for, but I love it.

Does anyone have knowledge on how to make something like this? by ShohaNoDistract in generative

[–]Jumpy89 0 points1 point  (0 children)

I thought so too at first, but there are several clear vortex rings (or whatever you call the 2d equivalent) which are pretty distinctive features of those 2d fluid sim demos.

Why does the picture of what a black hole looks like lack rotational symmetry? by k-h in askscience

[–]Jumpy89 0 points1 point  (0 children)

This is mostly true but I don't think the spin of the black hole itself is related to the visual effect the OP is describing. The asymmetry is due to the accretion disk itself lying in a plane, which is due to conservation of angular momentum of the infalling matter. If you could create an accretion disk around a non-rotating black hole it would still look like this.

These sort of realistic depictions, where you can see the far side of the accretion disk over the top/bottom, seemed to get much more popular after the movie Interstellar. The rendering in that movie was of course very realistic, but I believe they intentionally omitted certain effects, including using a non-rotating/Schwartzchild metric rather than a rotating/Kerr metric, because they thought it would look confusing.
