There is a good video here on Geometric Algebra, which is used in quantum physics. There is a really interesting bit in it that shows how complex numbers map directly to a geometry. All the rules that apply to manipulating complex numbers apply to manipulating this geometry, so its as if you already know how it works. www.youtube.com/watch?v=60z_hpEAtD8 |

Well, im not getting through, the reader needs you to decipher whatever, everyone does not have the time or inclination to watch a video in the hope of understanding.
The reader, who has no education in what you are saying, like me, relies on you to deliver an understanding, then give some sort of theory or improvement on whats already been said. Without that, this message is pointless.
Its like you hint at understanding it when you dont, and soak up the imagined kudos that posting this entails.
Who reading this, knows what Geometric algebra is, never mind understand it. Explain it, and what it produces in a practical way. . You say its as if you already know how it works. So how does it? You cant rely on a video because you dont get it, never mind having the ability to explain it to the likes of me.
What appetite is there for stuff like this?, but that wont stop you posting stuff no one has any hope of understanding.
But you, pretending.
Your grandstanding has no end. Now again. I dont get it. Explain it in a way i can understand. Im wasting my time arnt i? You will suggest im too stupid, in the old days it would be a volley of abuse. Over and over, ad infinitum, im as stupid as you for biting. Nothing i say will make a difference to you, im sure that thats a common thread in your life.

The video on it is the best way of understanding it, because if you bothered to look, you would see it would be very difficult to teach it on a board like this, as in we have animations and so on, so you can visualise it. I can't do the symbols here like curly d's and hats on vectors.
Did you do vectors in school? The video starts with a rundown of vectors, which you should know, and then gradually extends this into more advanced concepts. It's a very compact video with tons of things in a short episode. A tip when watching is to use the pause to read the equations properly. See how far you get. It's just glimpse of the beauty and orderedness of maths. It's just how god designed the universe.

I found some good short videos on Fock Space or what is called second quantisation. Standard quantisation is like energy levels in an atom but if you have many particles it is possible to create a way of working with them as a complete system. Each particle has a set of states, and in a system the system also has a set of states, as in all possible configurations of the system, call a canonical ensemble in physics. This is how you deal with combined quantum state like entanglement. The system as a whole has a set of rules, like for electrons the rule is they can't occupy the same quantum state, where bosons can. Also like with standard quantum mechanics you can have quantum operators that operate on the entire ensemble. You can deal with annihilation and creation of particles as well. www.youtube.com/watch?v=jAw9WMkcCj0www.youtube.com/watch?v=BhK6u0bMqG0&t=4s |

The people you are preaching too have trouble reading a gas meter. Where are the paragraphs?, i suspect the gas meter problem probably applies to you. Instead of trotting out endless stuff youve copied, why dont you show us your theories, which should be different from the stuff youve copied, in a step forward by the Baron way, instead of suggesting we read that and this, we can do that ourselves, if were arsed. Which we are not. For us to understand it, another big mistake, we need you to decipher the above then give your opinion. But you dont understand it either, do you, and it needs to be speaking to an eight year old way. You cant do that either. Your posts are one monumental waste of fucking time. I'm well inspired by this topic and learnt a lot of new maths in my attempts to understand it. It is making sense, but you have to understand these mathematical equations are from a long line of theories and derivations. It feels like the difference between understanding 100 lines of code and 100 000 lines of code. It has made me realise how little of maths is taught to you at university compared to how much there is. It is a vast subject.
By the way, I'm not you. You not understanding it does not mean others can't. The web is global so we have readers from better educated countries as well. This is for them. The q uestion becomes whether anyone on here has a use for that level of mathematics or whether they want to bother to learn almost as a hobby. |

I can't speak for others, but I like that Professor M guy in the last link. He's very clear and precise. I'm trying to wean people off pop science and into some serious mathematics.
