Before we talk about Promi

one of the things to do is we reach out to a bunch ofmetaphysics

Let's start by talking about succulent types

I've read the post on a magnetized resonator

Pacific's movies about getting thisness

with a very high quality resonator doこれで

and then I started showing you an experiment

that just showed that one hand couple,

and I had a magnet that I would have on the oscillator,

two signals thinned,

and now we're sort of in the middle of that experiment.

Just to remind you, this was the geometry

of the re-router, and that's how my magnet had

a tentacle we were over.

This is our interaction with the Hamiltonian,

and now we discussed the fact that one can scan,

a magnetic tip, and measure the DC magnetic field

emanating from this tip,

and then the question is if now one wants to couple it

to the motion of the resonator,

one wants to be sent to the AC field,

and how is one sent to the AC field?

Trying from the NMR and ESR developments,

one can use the simplest type of dynamic

coupling sequences on echo, just to try to represent it here.

And so here the idea is that as the cantilever oscillates,

the magnetic field at the end of the center oscillates

in time, and in order not to sort of average out

the AC magnetic field to zero,

one can sort of keep flipping your frame of reference

almost every time the magnetic field flips.

So it's almost like you're, say, watching the ball

bounce up and down, it goes up and down,

but if every time it starts turning over,

you can turn it over and go ahead,

it always looks like it's sort of moving up, right?

And so there's a flaw to that analogy

which I thought was important last night.

The flaw is that the balls are making that motion

in that analogy that I made.

In this case, what's happening is that the end center

is acquiring phase every time the magnetic field,

say, oscillates up, the magnetic field acquires positive phase,

and the magnetic field also goes down,

the magnetic field would acquire negative phase

because it keeps flipping, it continues to acquire
