Those are the good things, but those aren't the tastiest parts of the wheat.

Voiceover New Diamond Shreddies cereal.

little clump of little sand grains together.

But it didn't sit well with my logical side either.

And let's face it, everyone's trying to move towards whole grains.

(Laughter)

It's ideology, it's not science.

Particles

Afterwards we have to normalize to make sure all the weights add up to 1.

It can easily happen that the uniform value is so small that the same particle is picked twice, and it's easy to see that each particle is now picked in proportion to the total circumference it spans in this wheel of particles.

The analogy is that these people in a room are the Higgs particles.

If we place a single grain of rice on the first square of a chessboard, double this and place 2 grains on the second, double again and place 4 on the third, double again and place 8 on the fourth, and continue this way, putting on each square twice the number of grains than were on the previous one, by the time we reach the final square, we need an astronomical number of grains

And we came up with this analogy, and it seemed to work.

Well, particle physicists are nothing if not ambitious.

Number of particles

In the world of physics, they call appearance of the matter out of nothing,

What's that?

So these quanta of light aren't at all like the tiny, hard spheres Newton imagined.

The basic law, let's say here's an assumption.

This geo engineering idea, in it's simplest form, is basically the following.

Size of particles

Particle density

What's an elementary particle?

So, what you've gotten here is a set of particles that are all co located .

In fact, it is completely uncertain as to where it is.

Remember the third step in the delta debugging algorithm.

Well, that's what quantum mechanics teaches us.

This is the essence of particle filters.

I see.

Particle size

The first one was miniaturization.

One or both, who knows? Or it could be something completely different.

What I'll do next is to give you another program assignment.

And less sunlight reaching the surface would tend to cool the planet.

Four Particle beam. Check. Three.

She's waiting for the market to open a little impatiently.

So every grain of sand is unique. Every beach is different.

Well, light isn't really like anything we're used to dealing with in our everyday lives.

So one thing I want to stress here is that you've just programmed a full particle filter.

It ignores measurements, because the measurement sets the weighting factor in this resampling process, but with only 1 particle the same particle will be resampled no matter what.

Einstein's days vacuum was vacuum, but the quantum physics told us that vacuum is very much alive.
