Or you can just say, yeah, they're there.

I don't care.

They don't bother me.

They don't take up the resources we have in our world or anything.

No, that's the opposite.

The opposite.

So describe the opposite.

Copenhagen is the one that was invented by Bohr and Heisenberg back in the day.

And Bohr is the only one who's Danish in that pair.

He was slightly older than everybody else, and he founded the Institute for Theoretical Physics in Copenhagen, where all this work was done.

Well, there you go.

He had the money.

Heisenberg was a postdoc at this time and Bohr was a famous physicist.

The Copenhagen

puts in the laws of physics the notion of measurement.

It says that when you make a measurement of something, a dramatic effect occurs where the wave function that describes the system completely changes.

The real hardcore Copenhagen philosophy is that there is no such thing as what the system is doing before you measure it.

The whole of reality consists of nothing but measurement outcomes.

That's what Copenhagen actually says.

No, that's actually quite good.
