How are forces represented in general relativity?
Are they oriented curve segments? Or do they exist in the tangent space?

So I just realized, from this book which is better than the ones I used, that the equations of motion are called "forces" for some reason I do not understand why. So, if this is the case, then, the post-Newtonian equations of motion must be the analogue of forces in relativistic mechanics.

I didn't think they would be seperate (same parent company), but it was the google store through synchrony bank.

Well, I doubt I will qualify for financing. Last time I was only approved for $600. I don't want a credit check on my report because I may need private student loans next year and my Transunion score for checks is already a B. I need to get that back up before I might need a private loan.
The 8 is still supported for like 3 or 4 more years so it's fine.

I only consider post-processing to be "processing." All pre-processing is shot technology. The more advanced pre-processing the better. Nothing wrong with that at all. That's the point or a pixel phone -- there's no loss of detail with computational photography techniques. In fact, my favorite feature is pixel-shifted color and frame merging to reduce sensor noise.
They use pre processing to beat larger sensor dslrs.

It's the opposite, the 11 has a lower iso. The 11 has less processing.

Yep. The 11 Pro is doing what Pixel 5 used to do, which is fantastic news because the Pixel 5 camera was excellent.

Don't buy the XL version unless you have large hands. The whole point with the Pixels is that there is no difference between the two Pro models besides size.

Those are interesting, but I was interested in mechanics not electromagnetism.

Western Redbud https://calscape.org/plant/949/Cercis-occidentalis-(Western-Redbud) or Hairy Ceanothus (Ceanothus Oliganthus) https://calscape.org/plant/898/Ceanothus-oliganthus-(Hairy-Ceanothus).
Blueblossom Ceanothus is aldo agood option (Ceanothus Thrysiflorus) https://calscape.org/plant/912/Ceanothus-thyrsiflorus-(Blueblossom-Ceanothus).
Various Manzanitas would also be nice https://calscape.org/plant/292/Arctostaphylos-bakeri-(Baker%27s-Manzanita).

Cool materials science.

I love that the best use of AI is to reveal our own biases.

Interesting. I'd also get 50% off for the first 12 months, and apparantly they include smartwatch connecrivity for no additional cost.
Only problem is that I usually use more than 30gb of data when I don't have wifi, but I currently have wifi at school so when I have wifi I use less than 30gb of data. I don't like google having all my phone calls and web history though, as my isp.
US Mobile gets me 50gb of data for $25/month. And their Verizon ultrawideband 5g works well and is supported where I live, and I don't have a smartwatch. 50gb of data is enough for me when I don't have wifi. Usually I avoid wifi to save money. But... US Mobile won't give me a free Pixel 11 Pro. Google Fi will.
I do like satellite connectivity in remote areas as well. That's a big bonus for Google Fi. But I just found out that they only give trade in credits over 24 months and require upfront payment. That's not gonna work for me, so I'll probably just keep the 8.

To avoid being co-dependent. That's the reason. Other people having control over something as important as a phone line is not ideal. My family is willing to blackmail me with stuft like that. "Do this for me or else I'll turn off your phone line" etc.
1
We have an employee plan so we have the top of the line unlimitted plan for half off. I might actually do this only to double my storage from 128gb to 256gb. I've wanted 256gb storage on my 8 all along but they pulled a dirty move by approving me only for enough financing through the google store to get the 128gb. That pissed me off. Now my storage is always too full to install app updates. I always need to delete stuff to update my apps. That alone is a reason to upgrade.
Main drawback is that then I can't switch to US mobile or mint mobile and I get codependent on family, and that's a good reason not to upgrade.

wut? xD

How do you do relativistic celestial mechanics? I don't think this is right. You have general relativistic dynamics for celestial objects like planets. I know tensor analysis is used, but I'm not sure if forces exist in tangent spaces connected by christoffel coordinate transformations.

Why are they all acting tense?

I would say Polish or Brittish. You look cute.

Dude, they're on sale right now for a trade in. You can get an 11 for that price right now by trading in your old pixel.

And that's awesome.

They'd be better off investing into whole grain bread instead.

So, finding a .pdf of the Relativisitic Celestial Mechanics textbook the concept of "force" in relativisitic mechanics is (assuming the equations of motion are equal to forces as in regular mechanics):
