 Okay, so let's see what we can do here. So I'm just in front of a regular background. Now, what happens if I show my computer screen? I can be in front of my computer screen and I can open the presentation or I can just point around on my computer screen or I can start my presentation. So let's say I was talking about Coulomb's law. I can point some things out that are important. And then I go on this slide and now I wanna start talking or writing. So let's say the force is equal to K. Coulomb's constant Q1 times Q2 over radius squared. So in this example, I have nine times 10 to the nine Newton square meter per Coulomb squared times my charge one Coulomb squared times my charge one is three times 10 to the minus six Coulomb times my second charge, which is two, but we only take the magnitude. So minus three becomes two times 10 to the minus six over a centimeter is one times 10 to the minus two squared square meter. Here we have Coulomb. The Coulomb cancel the Coulomb, the square meter cancel the square meter. And what we are left with is nine times three, times two is 54 times 10 to the plus nine minus six, minus six minus four plus four. So nine minus six is three minus six is minus three plus four is 10 to the one. So 540 Newtons. And that's it. Now, okay, let's see what happens if I would try to erase. It's actually fairly simple. Okay, I'm gonna need the better towel to erase, but otherwise I think that is kind of proof of concept that this could work for life teaching. Here I'm recording my Zoom.
