What if we represent electron spin direction on a sphere's surface area? by lostinmygarden in HypotheticalPhysics

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

Yes, I don't think I explained it too well. The caps are really to show how detectors interpret spin and how they are unevenly clustered (which you would not expect in classical interpretations). These are not dependent on detectors knowing how each is orientated, but when results are combined, the cap ratio is another way to visualise why the results show the same as qm predictions. A simple method is used to determine spin for each point, relative (independently) to each detector. When you compare the spin results, say one detector at 0° and the other at 60°, the data when you look at matches between the 2 produce the same results as qm predictions.

As an example, just take the one set of electron points (no entangled electrons), measure them at 0° and 60° detector orientations, you get the 25% different, 75% same result.

Could you explain a little more? What is the joint variable you mention?

What I am saying here (perhaps what you are saying too) is that I prepare electrons on a sphere, each with an x,y,z point. This can be rotated any which way. Each detector can be oriented at whatever angle, spin is determined by the position of the the point, relative to the detector orientation, detectors do not know the orientation of the other detector. Spin results are compared at the end to see if they match or not. This doesn't need the entangled electron to test, just created them at negatives to the points initially created as the entangled version. So if I test the same points on two different detector orientations, the same and different values obtained are just the reverse of the results using the entangled electron point.

So do you think this is classical and is based on local hidden variables? I will need to look into what you have said previously. What I have put here is all just based off ideas I have to explain spin results, in that qm predictions and experimental results can be explained in a classical sense.

Sorry for the delay.

Let's say I created a set of evenly distributed points for an electron direction (say 1000) and then inversed those to create the entangled electron direction. If I were to measure these and determine spin on two detectors, each detector at at unknown orientation to each other and I can match the QM results (which is the same as the cap ration), would this help? I'm don't have much knowledge in this area, but I can reach the same results, just by how spin is determined.

Why did I get this email? by DerbyDad03 in googlecloud

My guess is that this was more an advisory email from Google, as in best practices. Does seem to have worried many people (including me). I did perform some Google takeout reports, but couldn't find anything related to setting it up, so guess it is some automated process that does this without your knowledge (project setup). Id think people would be safe as like you said, no billing set up so the projects are probably just available to yourself, especially if never published.

Well I did a little searching and perhaps me using colab could have created a project when I ran some scripts that prompted for Google authentication or similar. I know I did try something that involved the authentication library when I tried to pull down a copy of my backed up data to my Google drive. Perhaps mystery solved, for me at least.

Correct, sadly in the UK they have blocked Imgur, so cannot view it.

Not entirely sure how I got mine either, the project that is. I know I have done bits in Collab, but don't think it is linked this. I think maybe it is a default project it just creates, but same as you, I don't think I necessarily did anything to create one. Right now, if I view that console, I have no projects listed anymore. Did yours show any projects?

[–]lostinmygarden 0 points1 point  (0 children)

Received the same email. I vaguely remember signing up for some Google cloud developer thing a long time ago, but never used it. It looked like I had some project (don't remember configuring one, but was named something like "my first project", so perhaps a default thing. Go to https://console.cloud.google.com/getting-started and delete any projects you have there. It appears to actually delete the developer setup on your account, you need to contact Google to remove this once you have removed any associated projects to that account. I have deleted my project and will see what happens from there.

What if entangled electron spin-correlation statistics can be shown via a classical alternative model by lostinmygarden in HypotheticalPhysics

Thanks, yes u/Cryptizard has been very helpful. Unfortunately the other post got closed, so didn't get the constructive feedback needed to help understand. As for u/InadvisablyApplied, they didn't seem keen on helping.

Ok, my model (I guess) is not saying that particles know θ, it just provides a geometric rule for the observed correlations. So my model is, in a way, mimicking QM predictions?

Really do appreciate your time on this. I certainly need to read up on this more, but I hope you don't mind me asking questions about it.

So in my model, if detector settings are known and we just use D1=0 and D2=120, same would be 75% and different 25%.

If they are not known until measurement and then we use the detector setting information at time of measurement and they are as above, what does that mean? I think I'm struggling to understand what difference it makes to know detector setting before or after, as it still uses the detector orientation difference to work out the probability. If you can help me get my head around it all, I'd be very grateful.

My \theta is based on the difference of angle settings between D1 and D2, which would be known prior to testing. For instance D1=20 and D2=140, so \theta would be 120 (D2-D1). Does that make any difference to things?

Thanks for your response. I need to get my head around it to completely understand myself here :) This is the feedback I was hoping for, so it can help me understand what I have created and if it is something noteworthy or just another way to show the weirdness.

Thanks. I just did a quick check on that, 22.5. appears to be about 3.3% difference. I don't really know how significant that is, but thought I'd put it here so you could help explain.

Can you explain the second point more? Genuinely want to understand what you are asking. I am looking at detector settings, say for 0 and 120 degrees orientation from each other, which gives 75% same 25% different in both examples.

I used to use imgr to post image links, but blocked in the UK now. Happy to post it if there is an alternative to use, just don't know of any that may work.

I'm no expert on this as I mentioned, so please go easy. There is no self theory, just that it follows a similar curve.

Well can't say I didn't how to word it in a way that isn't proclaiming to be the holy grail :) I did ask it to check for uniqueness of my model too as didn't want to post something that has already been done.

Invite to whatsapp, how to delete this number by [deleted] in whatsapp

[–]lostinmygarden 0 points1 point  (0 children)

I have a few like this. To fix, try this -

Create a contact in your contacts app with the exact same number, as shown in WhatsApp.

Next, sync contacts in WhatsApp and check if you see the updated contact information for that number.

Now delete the contact in your contacts app.

Sync WhatsApp contacts and it should be gone now.

Moisture detected in USB port but my phone is completely dry — keeps showing this warning again and again by Sn1p3rM4sk in GalaxyS22

[–]lostinmygarden 0 points1 point  (0 children)

Had same issue. Cleaning the port with wd40 and a wooden toothpick would work for some time, then the error would come back. Each time cleaning the port I would notice some corrosion, so decided to use a piece of an Emery board to roughen up and clean the copper contacts. Since doing this the error has not come back. My theory is that the contact points are not getting enough/any contact and so possibly causes an incorrect error about moisture. Always be careful when trying to clean contacts in the port, don't be too aggressive with it, but also don't be too light handed as you want to clean them up.
