Jon shock received Lee Smolin's "The trouble with physics" from the publisher and showed it to me after reading it.
At the beginning, I saw five major problems listed by Lee in theoretical physics. The problem is as follows:
1. combine quantum theory and general relativity into a complete theory of nature.
2. solve the basic problem of quantum mechanics, or make the th
Thread Scheduling
====================
Windows has implemented a priority-driven preemptible scheduling system-the highest-priority running thread will continue to run, and the thread can only run on certain processors that allow it to run, this phenomenon is called processor affinity. by default, threads can run on any available processor. However, you can use the Windows scheduling function to set affinity mask in the image header to modify processor affinity.
When a thread is selected for ru
RSA encryption VS. Runway algorithmAs the Terminator of RSA cryptography-"Too many operations, unable to read"-The Shor's algorithm is not found by brute force, but by the parallelism of quantum computing, which can quickly decompose the number of conventions, This breaks the foundation of the RSA algorithm (assuming that we cannot effectively decompose a known integer). At the same time, the display algorithm shows that the problem of factoring can b

Two basic functions: void * kmalloc (siez_t size, int flags );
Void kfree (void * PTR );
In memory, a policy rather than a mechanism is used to select appropriate values for quantum and quantum sets, and the most important values depend on how devices are used. Therefore, device drivers do not need to force specific values to be used for the size of
Quantum Computation and Quantum informationDue to the relationship with the rapidly developing IT industry, quantum computing and the development of quantum information have attracted a lot of capital attention in recent years, with Microsoft at the University of California, Santa Barbara, which has a sation Q lab, foc

Of course, these ideas have developed dramatically in different fields. the Application of matrix and non-exchange multiplication in physics produces quantum

Genetic and evolutionary algorithmsLegacy algorithms (genetic algorithm) and evolutionary algorithms (evolutionary algorithm) are the result of interdisciplinary intersection. Genetic and evolutionary algorithms based on the characteristics of biological heritage, evolution and mutation, by simulating the natural evolution of the method t

These are variables, but they are also variables that can be determined during compilation. It is the application of C ++ templates and generic programming.

"electronics and photon" (we still remember that "photon-photon" is a new term, which was just proposed by us LIU Jun in 1926). The agenda of the meeting is as follows: first, Lawrence? Prague made an Experimental Report on X-ray, and then Compton reported the Compton experiment and its inconsistency with the classical electromagnetic theory. Next, debroitalian will give a speech on quantum new mechanics, mainly about the particle D. Afterwards, Bonn

The holographic principle is that a system, in principle, can be fully described by some degrees of freedom on its boundaries, is a new basic principle based on the quantum nature of black holes.

Peng Rose is not the only top mathematician who has created a quantum gravity method for himself. Perhaps the greatest one is, of course, the most interesting one. The Mathematician at the place is Alan o'konnis. I like to talk to Alan. Sometimes I don't understand what he says, but his profound thoughts and wonderful jokes make me happy. (Joke
1. hardware or software?
Most vrouters and vswitches support IPv6, but these network devices have different forwarding rules. A high-capacity core router processes data packets on its dedicated hardware (such as a dedicated integrated circuit or network processor) to accelerate IPv4 forwarding. However, the hardware architecture usually does not support IPv6. this means that the router processes IPv6 data packets on a general-purpose processor, which leads to slow forwarding and low capacity.

state of all the objects that make the natural life, in an instant: For this God, nothing will be uncertain; the future will be the same as in the past." Most physicists agreed to the above view before 1927. This Laplace deterministic asserted that, given the situation and situation of the universe at a certain moment, the situation of the universe at any moment in the future or in the past is completely determined. In western philosophical circles, this viewpoint is called "scientific certaint
