At present, the Turing proposition is also the same as the speed of light, through the test of history and time, now even if the development of quantum computers, or not to get rid of the Turing machine constraints, quantum computers can calculate the problem is common Turing machines can calculate the problem, but the computational efficiency is different.The two examples of non-computational

Summary of the bookThe author of this book is the famous Stephen Hawking .... It seems to be the words, God is closing a door, always open another window. Hawking, although physically hindered, but the thinking is no less than ordinary people, but also more than ordinary people.He put forward many well-known theories of physics.This book describes the c

Title Description:
John von Neumann, B. Dec, 1903, D. Feb. 8, 1957, was a hungarian-american mathematician who made important contributio NS to the foundations of mathematics, logic, quantum physics, meteorology, science, computers, and game theory. He is noted for a phenomenal mem

After reading the author's final note 3, I suddenly understood that von noriman's imperative computer architecture and the functional computer architecture of Aaron left Qiu Qi, it actually reflects two different philosophical views on the causal relationship between things:
Feng nuoman's point of view is to regard the world as a whole, and there is a specific link between different things. A change in one thing will also lead to changes in other things,

So for SQL, don't use nagle:)The cool is that the strategy for each vSERVER and service use, depending on the type of service peopl
What is a matrix?In mathematics, a matrix is a set of complex or real numbers arranged by a rectangular array, the first of which comes from a matrix of coefficients and constants of a set of equations. This concept was first proposed by British mathematician Kelly 19th century.Matrix is a common tool in higher algebra, and it is also common in applied mathematics disciplines such as statistical analysis. In physics, matrices are used in circuits, mechanics, optics, and
should it be regarded as an array or an object?As we know, arrays should be regarded as linear data structures. Linear data structures generally have certain rules and are suitable for uniform batch iteration operations, which is a bit like a wave. Objects are discrete data structures, which are suitable for describing scattered and personalized things, a bit like particles. Therefore, we can also ask: is the object in JavaScript a wave or a particle?If there is an object
Development of a flying and shooting mobile game similar to thunder fighter-game target, thunder fighter shooterRequirement Analysis
Since we are playing airplane games, what game targets do we need? Observe the pictures in the game under the camera. First of all, the main character is of course an airplane, including a gamer plane, dual-wing planes, and enemy planes. The aircraft is equipped with a variety of weapons: normal bullets, missiles, laser, etc. It would be too boring if the bullets
, but they lacked the Limit Concept, so they could not explain the movements. The famous paradox of zhino (four paradox s, such as flying arrows and flying legs, Achilles, and turtles) let's get it done. This article is not about calculus, so I will not talk about it much. If you are interested, you can go to Professor Qi minyou's "review calculus". I just read the beginning of this book to understand the truth of the sentence "Advanced Mathematics is a mathematical study of motion.However, in m
have to know that there is a "scale function", which is the key to the construction of the "wavelet function", and it is together with the small wave function to form a multi-resolution analysis of wavelets, it is possible to use the wavelet to do some digital signal processing; you also understand discrete wavelet transform, orthogonal wavelet transform, wavelet transform, Wavelet packet ...

From "Schrodinger's Cat",
The philosopher Schrödinger (Erwin Schrödinger) has an ideal experiment on quantum theory, as follows (for those who know quantum physics, please skip):
The cat was so pathetic that she (supposing it was a female cat to cause more compassion) was sealed in a Chamber of secrets with food-poisoned drugs. The poison bottle has a hammer, the hammer is controlled by an electronic swit

As if the global variable ability is very strong, can command the function inside and outside. However, be aware that this thing should be used carefully, because it is often easy to bring variable changes in the chaos. Inside and outside different, must notice in the procedure.
