Does God roll the dice-the history of quantum physics

If a physical concept cannot be measured, it is meaningless. Everything should be measurable and perceptible to this world of my oneness. Only observable quantities are present! (incompleteness theorem, Heisenberg uncertainty principle the low-dimensional world can not perceive the high-dimensional world, that is to explain the high-dimensional world.) Or I believe that the atom is four-dimensional or multidimensional, in short, is higher than the three-dimensional world exists, so it shows the wave force of duality. The two-dimensional language cannot describe high-dimensional information, so the language or presentation method determines how far we can look.

Theory determines what we can observe (i.e. the same mental pattern. A person's cognition determines what he can observe. What you believe and what you have. Or do you believe in the spirit? )
There is no absolute so-called "natural", unless you first define the way of observation. That the objective truth does not exist is how we measure or describe such things.
(using the arcane razor principle to remove the imaginary world, the rest of the world we can observe.) If it is not necessary, do not increase the entity. Is it possible to infer the dimension of the world by using the incompleteness theorem? ）
In other words, there is no objective, absolute world. The only thing that exists is the world we can observe.

First of all, the principle of uncertainty limits our understanding of microscopic things, and this limit is everything that has physical meaning. Secondly, because of the unavoidable disturbance of the observer to the observed object, the subject and the object world must now be understood as an indivisible whole. There is no "thing" that exists in the objective world in isolation (being), in fact a purely objective world is not, and anything can only be combined with a specific measure to talk about the specific meaning. The shape of the object is largely determined by the way we observe it. For the same object, these forms of representation may be mutually exclusive, but must be used in the description of the object at the same time, which is the principle of complementarity.

Structure and interpretation of computer Programs

Mental activities, in addition to trying to produce a variety of simple understanding, mainly manifested in the following three aspects:

1) The combination of some simple knowledge into a composite understanding, resulting in a variety of complex understanding.

2) Compare two realizations together, no matter how simple or summer. In doing so, they do not merge into one. This leads to an understanding of their interrelationships.

3) to isolate the knowledge from all other understandings that are in practice with them, which is abstraction, all of which are universally recognized.

　　　　　　　　　　　　　　　　　　　　

　

Out of their minds:the Lives and discoveries of great computer scientists

　　Linguists Benjamin Wolf once said: "Language shapes the way we think and determines what we think." "He is speaking in human language, and computer language is a further testament to this proposition, especially those that are inspired by the results of Backus, Macquarie and Kay," he said.

The key to success is the choice of the problem. Instead of finding a way to solve it. As long as you can find the right direction, as long as you can ask the right questions, you have begun to succeed, the problem is in front of the solution. To find the problem from the actual application. It is easy to get into the horns of theory, to immerse in the minutiae, but to lose the connection with the real world. I'm always looking at questions that have some practical implications, and I feel I can find more practical algorithms for them.

On the other hand, things can't be predicted. The ideas that arise in these isolated areas may sometimes be linked to other things. This is the magic of math and theoretical computer science. You're looking for some kind of universal principle. Suddenly there was some kind of mysterious connection. No one knows why.

All good ideas have a basic asymmetry-it's easy to know them, but it's hard to find them out of nowhere.
