Hello. This is Tenmei Watanabe from Seito Medical School. I'm currently reading a book by Adam Becker called ``The Ultimate Questions in Quantum Mechanics.''
This is the story behind the creation of quantum mechanics, but I noticed something while reading this book. There is a scene at the beginning of the book where the story is about ``Schrödinger's cat.''
Schrödinger's cat refers to the state of particles in which we do not know what state they are in until they are observed, similar to the state in which we do not know whether a cat in a poison gas chamber is alive or dead until the lid is opened. .
The device in the poison gas chamber generates poisonous gas under certain conditions, but you cannot tell whether poisonous gas has been generated until you open the lid and see if the cat is alive or dead.
Opening the lid means checking the cat and the particles, and it is determined whether the cat is alive or not when the lid is opened. It is called Schrödinger's cat because it is likened to a cat in a poison gas chamber because we do not know what state the particles are in until we observe them.
When I read this fiction, it reminded me of the philosophy of predetermined harmony, or determinism.
Determinism is a machine that can calculate the position and speed of all matter (including humans and living things), in this case called Laplace's Devil. It turns out that there is only a typical scenario.
In other words, if you have a brain that can calculate everything, it will be easy to predict the future. Sure enough, when I googled it, I found a search result saying that Schrödinger's cat violates determinism.
This Schrödinger's cat is also related to the Copenhagen interpretation of quantum mechanics. The Copenhagen interpretation in quantum mechanics is that the position and state of a particle cannot be determined until it is observed, and can only be understood as a size relationship based on probability.
There was something that struck me here again, and I was able to connect this idea to artificial intelligence's neural networks and deep learning.
By the way, even when I googled it in Japanese, I couldn't find any search results linking the Copenhagen Interpretation and deep learning at this time.
Deep learning is also a method of finding answers probabilistically, but I believe that consciousness and brain functions are random based on determinism, and that in the grand physical phenomenon of the universe, the delicate existence of humans and other living things. I thought it would be romantic if it was random and changed the world.
Of course, according to determinism, the human brain is also a substance, and the consciousness of the brain's functioning is determined in advance as a series of events from the past.
What I've been trying to say so far is that many disciplines, such as physics, philosophy, and computer science, reuse similar ideas at their culmination.
Economics and physics use similar ideas, such as the idea of maximum and minimum values, and size relationships such as micro and macro.
If you understand this, even when you learn a new subject, you will be able to understand it smoothly, thinking, ``Oh, this is the way of thinking of that subject.''
I've only read the introduction to the book I mentioned earlier, but I think ideas will come to you as you read through it. Ideas only have value when they are put into words.
Even if quantum mechanics is a difficult subject, it will be easier to understand if it contains a lot of content that has been quoted from other disciplines.
I am still inexperienced as a researcher, but I have been rapidly growing in many ways recently. I would be happy if I thought that this realization was part of that process.
Well, that's all for this article, but when you come across a certain way of thinking, try thinking about other similar ways of thinking. Maybe you can think of another, more closely related idea. This will speed up your understanding.
that's all. See you soon.
