量子物理：基态原子不辐射吗？
教科书上告诉我们的是：基态原子不辐射；这与经典电动力学相悖。经典电动力学说：加速电荷总要辐射电磁波。……in English
Quantum Physics: Doesn't the atom in ground state radiate?
Textbooks told us that the atom in ground state does not radiate and this is contradicted with
the classical electrodynamics. The classical electrodynamics says that the accelerating charges always emit
electromagnetic waves......

自己制作一定的ttf字体可行吗？……分形之曼德勃罗集图象的精确计算与生成-C++/GMP实现和验证
分形图像通常需要进行大规模的浮点计算，会对计算能力提出很高的要求。一般的浮点计算不可避免地会 遇到误差问题，未作误差分析的话，结果的正确性将很难判定。在生成Mandelbrot集图像时，笔者将运算范围限制在有限小数的运算上， 从而试图进行完全精确地计算……in English
Fractal: The Mandelbrot Set's Image Generation through Accurate Computation - C++/GMP Implementation and Verification
Massive floating point computation is normally needed to generate fractal images. This requires very high
capacity of computation. Common floating point calculation will inevitably meet the problem of error. Without
error analysis, the correctness of the result is hard to justify.
In computing the Mandelbrot set, I restrict the computation range to those of finite decimals, so to run absolutely accurate calculations......

Web建站：服务器程序“进程备份”
笔者在尝试建站。做软件者，自然最担心服务器程序崩溃；即便能重启，也要损失一些资源。这就产生了一种需要： 能否象数据可以备份从而损失时可以用于恢复一样，让服务器程序在崩溃情况下可以有个备份来用于恢复？读到过 Richard Stevens在《UNIX环境高级编程》中论述过的“传递文件描述符”，这种强大的功能象进程之间的dup/dup2有象 生成备份的意思，让我产生了想法：使用它来实现“进程备份”；当然了，这个不是备份一个进程“映像”，而是“备份” 一个进程中的文件描述符，包括我希望处理的网络连接的套接字。写了个小程序试了一下，成功。还有待于在大规模 服务程序中试用验证……in English
Web site: "Process Backup" of Server Programs
I am trying to construct a web site. As a software developer, he worries about server crash most. Even
the server can be restarted, some resources get lost. This incurs one need: can there be a backup copy for recovery
of the crashed server program as same as the recovery from suffering a data loss through data backup ? I ever read
about "passing file descriptor" in Richard Stevens' Advanced Programming in the UNIX Environment. This powerful
ability, which is like 'dup/dup2', but between processes, has some meaning of generating a 'backup copy'. And this
leads me to an idea to use it to realize "process backup". Of course, it is not a process image backup, but to back
up file descriptors in a process, including the networking sockets I wish to handle.
I wrote a small program to try this idea and succeeded. Need to test it in server program for large-scale service......
