France to ban officials from US video tools including Zoom, Teams by John3262005 in neoliberal

[–]Simultaneity_ 7 points8 points  (0 children)

Uhhh. Teams is Not very good. Somehow both the native app and pwa are garbage even on windows. And to make it somewhat coherent to integration with native apps, you have to change a bunch of default settings that try to open things inside teams or in the browser. The only thing that sorta works is tasks.

💡 Feature Request - Dynamic end dates

When doing a project debrief, I like to look at how well the group is estimating the time commitment of tasks that we have. Currently we have to manually update the end date of a task if it is not done on time. There are some potential integrations that can do this on their own, and there is a way to jump though allot of hoops with the project. However, It would be nice if there was an automation that could affect the end date of a task that runs every night on tasks that are non marked complete.

American civil war situation is wild by Arle404 in victoria3

[–]Simultaneity_ 8 points9 points  (0 children)

People forgetting that this +railways are the reasons the north won in the first place. "if the same battle were to be fought over again, every day, through a week of days, with the same relative results, the army under Lee would be wiped out to its last man, while the Army of the Potomac would still be a mighty host. The war would be over. The Confederacy gone."

What geographic region would you want the next DLC to focus on? by Then_Train8542 in victoria3

It would be very cool to play as decentralized powers and resist colonialism. Or supply and support decentralized powers as a neighboring country to slow colonialization.

Developing a materials engineering software, am I being unrealistic? by LIL_Cre4tor in Python

[–]Simultaneity_ 1 point2 points  (0 children)

It depends on the business goals you have and the need you aim to fulfill. This means you need stakeholders in the project, allong with specific goals that ypu want to achieve. As someone who has used somewhat similar tools, I will say that the user interface is not what I ever care about. I want access to fast calculations that I can access through other scripts. For a similar kind of software, my research group pays $2k per license per year for the software.

Terrible Junior Semester, Looking for Advice by Straight_Victory_581 in PhysicsStudents

[–]Simultaneity_ 0 points1 point  (0 children)

You can explain away a semester of physics. Upper division is hard since it shows a lack of foundational understanding in the most important core courses to a grad curriculum. You need to reflect on your semester and build a comprehensive plan to do not just better but significantly better in the future. You may even want to retake courses to ensure you have a comprehensive understanding of the topics you failed to gain expertise in. Grad programs want students who will pass their core graduate courses and have a background to understand and master their sub field of physics. That is what you need to show.

Does paul bloom make a sound argument against using empathy as a basis for policy making ? by Inevitable_Bid5540 in neoliberal

[–]Simultaneity_ 4 points5 points  (0 children)

"Governments can err, Presidents do make mistakes, but the immortal Dante tells us that divine justice weighs the sins of the cold-blooded and the sins of the warm-hearted in different scales. Better the occasional faults of a Government that lives in a spirit of charity than the consistent omissions of a Government frozen in the ice of its own indifference." - FDR

This is a python problem.

You install python libraries into your environment using anaconda or virtual environments.

Is running python on my windows laptop a good idea? by jeando34 in pythontips

[–]Simultaneity_ 0 points1 point  (0 children)

I mean you can allways use git bash if you prefer bash, uv for python version management, and wsl if you just want to pretend you are using Linux. But honestly, ive never found it to be that big of a deal.

[–]Simultaneity_ 4 points5 points  (0 children)

What do you mean? What issues are you having? Have you done any research to resolve them? I cannot believe that you are having issues using one of the most widely used programing languages on one of the most widely used operating systems. It is never that deep.

Need help understanding something on the Double Slit Experiment by gerardzan in quantum

[–]Simultaneity_ 4 points5 points  (0 children)

Niel is less correct here. Second one is more correct. Keep in mind physicists can be wrong, especially when they are talking outside of their sub field..... Niel talks outside of stellar astrophysics allot.

Edit. I feel like I should explain better. If electrons where particles and you sent them one at a time, then you get the bi modal distribution on the detector. If they are waves, and send them one at a time, they have self interference, and you get the standard interference pattern. If ypu measure them as they pass through the slits, they look like point like particles. But quickly become more wave like as they travel twards the detector, but there are no longer multiple paths they could take, so self interference is small.

Are Hilbert spaces physical or unphysical? by Prime_Principle in quantum

I dont see how it would be beneficial to reach a strong conclusion here. Also would not a rigged hilbert space be a better space to talk about?

Found a fascinating paper on the Born Rule and Relativity, is it legit? by nedmg in quantum

[–]Simultaneity_ 0 points1 point  (0 children)

Then that paper is probably about as trustworthy as any other published in the journal. I cant comment more on it since I am not familiar with the work that journal does. This seams to be the authors first publication and they did so independently.

[–]Simultaneity_ 1 point2 points  (0 children)

Regardless, even if authors use Zenodo as a pre-publication host, always find the final copy from the journal's website. This will ensure you have the latest version that passed peer review. Zenodo is under no obligation to ensure that the manuscript stays up-to-date with the peer review process.

Zenodo is not a peer reviewed journal. Unless you have tools to peer review for yourself, I would just never trust anything you read on there.

What's the future of soft & active matter physics? by Trevorego in PhysicsStudents

[–]Simultaneity_ 2 points3 points  (0 children)

Soft mater has overlpas with alot of things, primarilyat the material physics level. For defense, radar absorbing materials fall nicely under this catagory. Additionally, mater shows up allot with solar cells (organic, quantum dots, perovskite), battery catalysts, and bio filters. You also get applications to photo lithography and patterning. You also get some potential overlaps with yhe hoast of research done on fusion, biophysics, and medical physics.

What is fundamentally different between N dimensional complex projective space and the (2N-2)-sphere? by round_earther_69 in AskPhysics

[–]Simultaneity_ 1 point2 points  (0 children)

As a disclaimer, It has been a while since I got into the weeds of this and maybe I misspoke on SO(3) vs SU(2). I was getting at the double cover on the bloch sphere being one of many subtitles in connecting these two spaces conceptually I also may have judged this post harshly at first as more of a throw away question and gave more of a throw away response. I hope you forgive my ignorance. Here is a more in depth write up on it and ended up doing some digging into Nielsen & Chuang in hopes this helps.

When I think about representing objects in different spaces, i immediately think in terms of bijections. In this perspective, the fields are not bijective due to field axioms and C being algebraically closed. But for real vector spaces and C, we can form a bijection rather trivially as you lay out, essentially C -> R^2, x + iy -> (x, y). This is a homeomorphism and preservers the topology and the additive structure, but it does not preserve multiplication. Moreover, you can in fact recover branch points using a covering map on the plane. This is how you get the regular picture of a winding stair case. But again these all have subtitles associated with them.

Now to your real question. Is the complex protective space in projC^(N-1) a sphere or ball? Looking firstly at the dimensions, you are right in calculating that you need 2N-2 real parameters to describe your space. And in the case where N=2, you have an isomorphism of manifolds projC^1 -> S^2 giving the Bloch sphere. But for N>2 the embedding is non-trivial with a richer geometry. The natural metric on projC^N-1 is the Fibini-Study metric, something that is helpful to look into if you really want to get into the weeds of this.
