I’m pretty happy with the one in my country. I once mixed up some medication times and they escalated to a doctor that then put me on hold to consult a pharmacist just to be sure. I would have spent 7 hours in ER just for a doctor to tell me that I was fine, and instead I just waited a bit on the phone.

USA, Land of the free to pay 🤷 in my country it’s all completely free. Once I had a bad cold they even called me back the next day to check in if I was doing better.

Since you’re in the US I imagine my method won’t apply to you, but just in case, or for other people reading: in my country there is a phone number you can call in situations like this. They have doctors, nurses and specialists on call, initially you talk with a nurse that asks triage questions once you’ve explained your problem they give you advice for home treatment, if relevant, or send you to the correct urgency level care, including already sending the information on the triage questions to wherever you are going.

Thanks for the reply, it hasn’t fully clicked yet, but I’ll get there once I think about it some more.

Happy to help! Now what I don’t get under this knowledge is double and triple rainbows. If anyone can explain that to me I would be very grateful.

You’re almost there. It has to do with the angle of the sun and the water drops relating to the view point. Rainbows only show when the sun is behind you, and if you imagine a cone going out from the viewpoint outwards you get the possible paths of the rainbow (different radius different wavelength and therefore color)

A similar concept happens in certain reflective surfaces (metal pots and pans, car hoods and much more). You always see the tiny scratches in circles, but if you alter the angle in any way you keep seeing different scratch circles. This is because the circle you see in any given angle is the exactly the scratches that are turned just perfectly to reflect the light in the perfect way. It does not mean that the scratches you see at any given moment are the only ones. It means there are plenty, and only a few more visible at a time.

To me, playing around with the second concept (much easier to manipulate yourself and see) made me understand rainbows much better.

The way I’ve explained it before is that it’s like the autocomplete on your phone. Your phone doesn’t know what you’re going to write, but it can predict that after word A, it is likelly word B will appear, so it suggests it. LLMs are just the same as that, but much more powerful and trained on the writing of thousands of people. The LLM predicts that after prompt X the most likelly set of characters to follow it is set Y. No comprehension required, just prediction based on previous data.
