You may know that I continue to make several kinds of "simulator" on a day-to-day basis.

Basically, I like to make simulation programs. Moreover I am a

"Native speaker of C/C++ (program) language.

even if the language has a bad reputation,

If there is a nation whose name is "C/C++ kingdom", I believe firmly that I don't have to worry about communication in the nation.

I don't need any illustrative sentence book and sightseeing brochure.

Above all, I feel proud that I am one of wise old mans who can use "ancient spell language" that enables me to touch a computer operating system directly, with some system calls.

However, I am afraid that the words of "I like simulations" means, on the contrary, "I dislike mathematical model".

The other days, I wrote a story that my simulations duration became zero, by a mathematical model that a reader presented to me.

My enforced simulations (which use a lot of random numbers and objects) are

more "ugly and awful"

than mathematical models( based on statistic and differential equation)

Of course, it was true that the performance of computers of old was too poor to do the "enforced simulations"

So, we have always needed more computer performance, especially in the field of physical science, for example, magnetic, electric and weather analysis, there is no reason that we don't need any more performance.
