Dear Mn,

You can delete “finished”.  “After the second world war” conveys the thought by itself. 

You don’t have enough space after any of your punctuation marks.  You need one space after a comma, two spaces after a full stop.  This is extremely important. 

You have a few spelling errors:  destroyed, people, appeared, until (or ‘til).

You need to work on the agreement of your verbs.  Sometimes, within the same sentence, you use have and had.  In some cases, you don’t need them at all.  You can just use a simple past or present tense.  It all depends on what you’re trying to say.

Your final statement, “now it’s one of the most demanded fields in the world” is unsupported.  This is known as “peacocking”.  Here’s an article on how to avoid peacock terms.
