 Hi. Gwyn i'n cael y ddweud y ddweud y Fflawn Arlun? Dwi'n rwy'n credu i ddweud y ddweud y ddweud o'r cwestion a ddweud sydd yn gwneud yn ddweud. Rwy'n credu'n gwneud, yna ymlaen… Yn gyffredinol? …a'r byd y ddweud yn y ddweud? Rwy'n credu, rwy'n credu'n gwneud. Rwy'n credu'n gwneud y ddweud. Cymraff o'r dda i'r eich cyfle, I alluded to to it called the Schrodinger equation. There is a way in which we can, shall I say recast that so that we get what's known as an operator form of it. Basically what we did here today, that form is that within how we explain that equation, ond we can literally destroy a particle and we can create it again into another state. And so it becomes part of the mechanics, the quantum mechanics of what we can actually do with our system and all of that information is then put in at the equation level and out of that, like what we've got, we've got all these different possibilities that can happen and then we have to look at the quantum statistics which sit on top of that. We can take a snapshot of an average of what's going on. That's basically what we do. But to be a bit more specific about your question, we need to put in the kinetic degree of freedom into our particles. And so our electrons, what they actually see in this model is they see the atomic-like states that they can be in and the way in which the mechanics works in the model is that they get to move from atom to atom and they're able to move. And because we have to keep the same number of particles, we can't put more in or take them out in our system, is that we have to literally destroy them and create them elsewhere in our structure. Is nanotechnology, how is it powered? Where does it get the energy to do what it does? OK, so that's also a very good question. With a lot of these technologies, let's go back. For example, this one here. Let's have a look at this quantum dot. Amazingly, this little quantum dot is connected to the outside world by very, very tiny nanowires. So this is part of the technology design that we also need to be considering. You're right, they can't live in isolation. They need to be connected somehow. With the nanoparticles, they don't so much need to be connected because if you've got an external magnetic field which is acting at a distance, they can do their job very nicely. You just have to get them in the body. But some of the nanotechnologies do need to be connected to the outside world and that's how we drive them. We can put a little gate voltage across it and drive the electrons in that way.
