Adios, Fortran. Hola, Python!

As far as I am concerned, there are hundreds of disciplines related to scientific computing realizing their calculation via Fortran language. Fortran, originated at 1950s as a short name for formula translation, is considered to be the first computer language which design for pure science calculating. Once, Fortran is dominant with glory and pride, while it is fading away significantly.

Many of us have long hold a misconception that Fortran is the fastest computing language. Frankly speeking, Fortran routine executes fastly as well as cheaply, and that is why it is so popular for more tha fifty years. Apparently, however, it is definitely not the fastest. For example, assembly language is definitely faster than Fortran, though it is complicated in coding. Holistically, the true advantage of Fortran is a fabulous balance between performance and coding cost. In addition to that, “first” itself may be an advantage either. I often hear scientific reseachers who are reluctant to learn a new language such as C or Python said that there are lots of past programs written in Fortran, we should better keep this consitency for tranplatation and some other reasons. In my opinion, the reason is bullshit as well as blindness. Most of the historical “legacy” are illy written(not readable, not aligned, lack of annotations and etc) because the majority of those writers are amateurs, or even noobs, I often got the impulsion to rewrite a new one, a better one. In addition to that, the old-fashioned grammar and structures have brought in other flaws. Thus, the value of those heritages must be revalued, like Nietzsche’s, and there is really little worth of historcial codes.

Here are the Tiobe index(rankings) which denotes the popularity of programming languages, please note that these are average positions for a period of 12 months.

Programming Language 2015 2010 2005 2000 1995 1990 1985
Java 1 1 2 3 31
C 2 2 1 1 2 1 1
C++ 3 3 3 2 1 2 9
C# 4 5 6 10
Objective-C 5 8 42
Python 6 6 7 25 9
PHP 7 4 4 21
JavaScript 8 10 10 7
Visual Basic .NET 9 192
Perl 10 7 5 4 5 17
Pascal 17 14 17 18 3 7 6
Fortran 25 25 14 17 18 3 5
Lisp 28 15 13 8 10 6 2
Ada 29 22 16 19 4 9 3

As we can see, Fortran fell steeply since 1990, while Python keeps a steady position.

So, wake up, dress up, and python up.

In a tranquil night, emotions arise from the deep of my heart.

Today is Mid-Autumn Festival, a traditional as well as significant event of Chinese for family reunion and enjoying the full moon. Hope everyone all over the world joyful tonight.

As for moon, there is numerous moving fairy tales from Greece to Japan, and China is no exception. The story of a pulchritudinous lady, Chi’ang -Er, is probably the most intriguing one. She had stealed panacea and then flied to the moon like a rocket man, living with a cute rabbit problem-free but deeply lonely. It is hard to retrieve the origin of this story and the people who conceived it. 

Apart from China, we have Daphne, Luna and etc. Thanks for modern science and technology, we now know that there is no beauty lives in moon. And moon is just a satellite orbiting the earth with desert and silence. It is a kind of pity that science breaks up our good beliefs once again, replacing lovely imagination by dumb numbers.

Scientific evidence tells us the precise position of celestial bodies, but never informs us where we are and who we are. Thanks the beautiful minds who created those fragrant folklores, which  maybe specious but plausible.

Thanks to all good things.

Thank you.
