1. God doesn't play dice with the universe. Einstein said that. When something happens, it is because of circumstances that already exist. Every action is the consequence of another action. (1)
2. We are all related. That's the theory of entanglement. If something affects the quantum state of one particle, it will inevitably affect the quantum state of the other, even from the other side of the world. The way I see it, no matter how far apart we are, we can still affect each other. They are weird when people come back. We are who they are. (2)
3. Triangle: All of them are connected, but only two of them can connect at one time. Those three lines never touch at a single point. (3)
4. Unintended consequences are outcomes that are not what you intend in a particular situation. The law is each cause has more than one effect, and these effects will invariably include at least one unforeseen side effect. What is weird is the side effect is potentially more significant than any of the intended ones. (5)
