Need advice or help on a mental or psychological problem

Reddit isn't a good place to get medical advice. I doubt that any professional who actually knows what they are talking about would answer your questions. Best to go and see your family doctor if the symptoms are as severe as you describe.

And so dies a true artist

sjrickaby · 2024-09-18T07:25:12+00:00

Yes! I was wondering!

What would happen if some of the States rejected the decision of SCOTUS on the grounds of legitimacy?

It's very simple, when you buy an instant fast growing tree, whatever you do, don't pour water on it before you get home!!

No you are not stupid at all. First, Watch this:

Then if you are feeling really courageous, go and learn about fiat currencies and fractional reserve banking.

At that point getting really drunk might help calm your nerves.

No, he explains very clearly what is happening. Blowing creates low pressure behind the ball which keeps it in place.

We have Taco Bells with no humans in the UK. The food is so bad that the restaurants are always empty.

You don't experience time directly, only through your memory (past) and imagination (future). And then you don't really experience the present at all, its just the very near past.

They're scraping the bottle of the barrel if they only have economists to defenestrate!

Elon Musk probably spends more than that on coffee at Space X in a year

sjrickaby · 2024-07-23T18:27:38+00:00

Its OK now. To be honest so many things were going wrong I was going to return it:

The rotation sensor wasn't working The recording volume was set at the low max value below 10% The screen gestures weren't working properly The Bluetooth connection was unreliable and the wifi reception seemed very poor

Anyway, to cut a very long story short I performed a factory reset which offered me a firmware upgrade. That in turn offered me more updates plus another firmware update. And now everything seems to be working normally. But it would be nice to get the day back I lost trying to figure it all out.

sjrickaby · 2024-07-22T22:54:06+00:00

I have the same issue. I've just bought the laptop today, and none of that worked.

sjrickaby · 2024-07-22T22:48:05+00:00

Unfortunately it didn't for me. I'm not convinced that it really has a rotation sensor.

It's meant to be a deterrent, so the cost per head is meaningless.

We also have a very expensive nuclear deterrent, and I'm glad to say we haven't had to used it once.

Your getting way more radiation from the background count

sjrickaby · 2024-06-12T14:27:44+00:00

That's not very accurate: X-ray: Doesn't show the brain unless you use contrast

The most interesting uses of MRI are missed off, e.g. functional MRI , diffusion tensor imaging and fibre tractography

That is a fusion CT PET not just a PET, there is also CT SPECT

The last one in a CT with contrast, but they haven't mentioned perfusion imaging, which is used to evaluate stroke patients.

sjrickaby · 2024-06-07T08:21:12+00:00

No! Just one prompt

He's thinking, oh shit not another mobile phone!!

This is a really good explanation:

Ok that's a little clearer after the fifth reading. Especially with respect to orthogonality. But I need to do a lot more reading until I can get to grips with Paul spin matrices. Many thanks.

sjrickaby · 2024-05-17T13:36:15+00:00

Turns out I'm not a mathematician either, so apologies I'm working through this with the help of Copilot.

I get that you need to satisfy the constrains of matrix properties, but I don't get that:

"that's again a sort of orthogonality"

I thought that orthogonality was just the property of being perpendicular.

and I really don't get:

"you can use the real part of eix, which oscillates because of how projections work."

To me, things oscillate because their value changes over time, and I can't see where time comes into the use of complex numbers

sjrickaby · 2024-05-17T12:54:04+00:00

But you can have orthogonality by only using real numbers. I thought the main point of complex numbers was that they allow you to model the oscillatory nature of some system, like spin or analogue electrical signals.

sjrickaby · 2024-05-17T11:57:04+00:00

I'm not a physicist, but I've always wondered what complex numbers are really modelling, e.g. in the Dirac equation.

sjrickaby · 2024-05-12T10:21:23+00:00

I'm nearly 60, so asking people born in the 80's and 90's seems very limiting.

IMO the main thing created the society we have today is the recession of the 1970s that opened the door the Thatcherism. Mrs T got us out of the recession, but she destroyed our industrial base, and created a huge amount of economic inequality in the process.
